These cautionary statements should be considered in connection with any written or oral forward-looking statements that we may issue in the future. We do not undertake any obligation to release publicly any revisions to these forward-looking statements after completion of the filing of this Annual Report on Form 10-K to reflect later events or circumstances or to reflect the occurrence of unanticipated events.

Item 1.

Business

Overview

XOMA Corporation (“XOMA”), a Delaware corporation, discovers and develops innovative antibody-based therapeutics, including those that have unique allosteric modulating properties. Our lead product candidate, gevokizumab, is a proprietary potent, fully humanized allosteric-modulating monoclonal antibody that binds to the inflammatory cytokine interleukin-1 beta (“IL-1 beta”). We believe that by targeting IL-1 beta, gevokizumab has the potential to address the underlying inflammatory causes of a wide range of diseases that have been identified as having unmet medical needs.

Together with our development partner, Servier (“Servier”), a leading independent French pharmaceutical company, we initiated three Phase 3 clinical trials evaluating gevokizumab for the treatment of non-infectious intermediate, posterior or pan-uveitis (“NIU”) and Behçet’s uveitis, a severe subset of NIU. XOMA is responsible for all of the clinical study sites in the United States, and Servier is responsible for all of the clinical study sites outside of the United States. These studies are known as the EYEGUARD™ program, which includes EYEGUARD-A (patients with active NIU), EYEGUARD-B (patients with Behçet’s uveitis), and EYEGUARD-C (patients currently controlled with systemic treatment).

In addition to the NIU clinical trials, we also are conducting a trial of gevokizumab in pyoderma gangrenosum (“PG”), a rare ulcerative skin disease. Based upon what we believe are compelling data from our pilot study in patients with PG, we requested an End of Phase 2 meeting with the U.S. Food and Drug Administration (“FDA”) to solicit feedback on our proposed Phase 3 clinical development program.  We have been granted a Type B meeting, which we expect to occur in March 2014 and to receive feedback from the FDA early in the second quarter of 2014.

We also have an active gevokizumab Proof-of-Concept (“POC”) development program to identify indications for pivotal development. We conducted POC trials in moderate-to-severe inflammatory acne and in erosive osteoarthritis of the hand (“EOA”), and we have several other ongoing POC studies. In early 2013, we reported top-line results from our moderate-to-severe inflammatory acne study.  Based upon market analysis, we have decided not to pursue a pivotal program in moderate-to-severe inflammatory acne; however, we will consider conducting pilot studies in rare acne indications classified under the umbrella diagnosis of neutrophilic dermatoses.  In October 2013, we reported promising results from the Day 84 pain, stiffness and function endpoints in our gevokizumab POC study in patients with EOA and elevated C-reactive protein (“CRP”), known as Study 160.  At the same time, we announced we completed patient enrollment in a supplemental study for patients with EOA and non-elevated CRP, known as Study 162. On March 4, 2014, we reported that despite early positive results in Study 160, the top-line data at Day 168 in that study, as well as data at Day 84 in Study 162, were not positive.  These results led to our decision not to pursue Phase 3 testing in the broad EOA population.  We will continue to review the data to determine if there is a subgroup of the EOA population that could benefit from gevokizumab therapy.

Gevokizumab has been generally well tolerated across all of our clinical studies.  In both the acne and EOA studies, there were no drug-related serious adverse events reported. The most common adverse events were headache, pain, arthralgia, urinary tract infections, upper respiratory tract infections and pneumonia, and they were comparable between gevokizumab and placebo.

We also have ongoing clinical studies assessing gevokizumab’s potential to treat several other rare diseases. Two studies are being conducted in collaboration with the U.S. National Institutes of Health (“NIH”). In March 2013, we announced that a gevokizumab study in patients with non-infectious anterior scleritis had opened for enrollment at the National Eye Institute (“NEI”). In August 2013, we announced a gevokizumab clinical study in patients with inflammatory autoimmune inner ear disease (“AIED”) run by the North Shore-Long Island Jewish Health System in collaboration with the National Institute on Deafness and Other Communication Disorders (“NIDCD”).

Separately, Servier instituted its own active development program for gevokizumab beyond the NIU and Behçet’s uveitis Phase 3 program. In 2012, Servier initiated a gevokizumab Phase 2 study in patients with acute coronary syndrome, a cardiovascular disease.  In 2013, Servier also began testing gevokizumab in a variety of POC studies, including polymyositis/dermatomyositis, Schnitzler syndrome, and giant cell arteritis. Servier has indicated these are the first studies in an extensive multi-indication exploratory program it expects to conduct.

Our proprietary preclinical pipeline includes classes of allosteric modulating antibodies that activate, sensitize or deactivate the insulin receptor in vivo , which we have named XMet.  This portfolio of antibodies represents potential new therapeutic approaches to the treatment of diabetes and several rare diseases that have insulin involvement.

We have developed these and other antibodies using some or all of our ADAPT™ antibody discovery and development platform, our ModulX™ technologies for generating allosterically modulating antibodies, and our OptimX™ technologies for optimizing biophysical properties of antibodies, including affinity, immunogenicity, stability and manufacturability.

Our biodefense initiatives include XOMA 3AB, a biodefense anti-botulism product candidate comprised of a combination of three antibodies.  XOMA 3AB is directed against botulinum toxin serotype A and has been developed through funding from the National Institute of Allergy and Infectious Diseases (“NIAID”), a part of the NIH. A Phase 1 trial was completed on XOMA 3AB, with no product-related serious adverse events. In January 2012, we announced that we will complete our NIAID biodefense contracts currently in place but will not actively pursue future contracts.  Should the government choose to acquire XOMA 3AB or other biodefense products in the future, we expect to be able to produce these antibodies through an outside manufacturer.

We also have developed antibody product candidates with premier pharmaceutical companies including Novartis AG (“Novartis”) and Takeda Pharmaceutical Company Limited (“Takeda”).  Two antibodies developed with Novartis, LFA102 and HCD122 (lucatumumab), are in clinical development by Novartis.

Corporate Strategy

To ensure we capture the value from our product discovery and development programs, we are committed to establishing XOMA as a commercial organization in the United States. Our commercialization strategy is to market XOMA’s products to the U.S.-based specialist prescriber through our own focused sales teams. For example, when selecting indications for gevokizumab clinical development, we investigate published data that supports IL-1 beta’s role in the disease state and supplement the clinical evidence with data that indicates the affected patients are treated by a specialized physician base. When our compounds target indications that will require clinical studies that are prohibitively large or the targeted patient populations are not treated by specialist providers, we will seek a development and commercialization partner. For example, we will seek a partner for two of the compounds in the XMet platform, as they target Type 1 and Type 2 diabetes, and we will retain the third, which targets several rare indications for individuals with dysregulated insulin production.

Additionally, we may seek to expand our pipeline by developing additional proprietary products and technologies and by entering into additional licensing and collaborative arrangements with pharmaceutical and biotechnology companies.

The principal elements of our corporate strategy are to:

·

Complete Phase 3 clinical development for gevokizumab, our lead product candidate, in non-infectious uveitis. With Servier, we launched the global gevokizumab Phase 3 clinical development program, named EYEGUARD™, in 2012. The global program includes two Phase 3 trials in active and controlled NIU (EYEGUARD-A and EYEGUARD-C, respectively) and a Phase 3 trial outside the United States in a subset of NIU patients who suffer from Behçet’s disease (EYEGUARD-B). The EYEGUARD-A study defines active NIU as a vitreous haze score of equal to or greater than two on the SUN/NEI scale. The vitreous is a normally transparent gel that fills the eyeball behind the lens, and vitreous haze is the clouding of that gel. The EYEGUARD-C study is designed to determine if physicians can reduce or eliminate corticosteroid use from NIU patients without causing their disease to flare, or exacerbate. The EYEGUARD-B study also is designed to determine if physicians can reduce or eliminate corticosteroid use from Behçet’s disease patients without causing an acute exacerbation of their uveitis. In addition to establishing efficacy, we believe these trials have been designed to provide data necessary to meet the FDA minimum safety requirements for ophthalmic indications: at least 300 patients must be treated for at least six months and 100 patients for one year at the to-be-marketed dose.

EYEGUARD-A and -C require 300 patients to be enrolled in each study.  The pace of enrollment in both studies has been slower than both Servier and we had anticipated. We increased the number of study sites in the U.S. to 70, 69 of which are now open, and we have implemented and continue to implement a variety of activities to accelerate patient enrollment.  We are seeing slow but steady progress in enrolling patients in the United States, particularly in EYEGUARD-C.  As of March 1, 2014, Servier has obtained regulatory approval for EYEGUARD-A and EYEGUARD-C in 19 of its targeted 23 territories.  These countries represent 61 of the planned 70 clinical sites in the Servier territory, and opening the study sites in Servier’s territories is crucial to getting the EYEGUARD-A and -C studies completed.   For the EYEGUARD-A and -C studies to reach their primary end points in 2014, we must increase the pace of enrollment at the U.S. sites, and both studies need a sizable bolus of patients from the recently approved countries of Argentina, Mexico, Turkey, Armenia, and Brazil. We believe we need positive results from any two of these three studies in order to file a Biologics License Application (“BLA”) in NIU with the FDA.

·

Pursue a Phase 3 program in PG, a rare skin disease classified under the broader indication of neutrophilic dermatoses . In late 2013, we launched a pilot study to determine gevokizumab’s ability to treat acute inflammatory PG, one of several rare skin diseases classified under the broader cluster of neutrophilic dermatoses. We designed the study to enroll as many as eight patients to receive gevokizumab, dosed once monthly for three months. Of the six patients dosed with 60mg of gevokizumab, five patients had a reduction in the size of the target ulcer and four achieved complete closure of the target ulcer with no sign of active PG by day 84.  We will present the data from all six patients to the FDA as a part of the Type B meeting, which will be held in March 2014, during which time we will request FDA guidance on the requirements for a Phase 3 program in PG.  We anticipate having the FDA’s feedback on our proposed PG Phase 3 program early in the second quarter of 2014.

·

Advance secondary Phase 3 clinical development strategy for gevokizumab in Behçet’s uveitis. As a parallel strategy to accelerate our path to commercialization, we plan to seek guidance from the FDA to determine the requirements necessary to support a BLA in Behçet’s uveitis. In 2012, Servier launched an open-label Phase 2 study in patients with Behçet’s disease and a history of severe uveitis who were treated with corticosteroids and at least one pre-specified immunosuppressant. Fifteen evaluable patients presented with elevated vitreous haze resulting from their Behçet’s uveitis. All of the evaluable patients responded to gevokizumab treatment, most within one week, and all of the patients had vitreous haze reduction of at least one unit. Eleven of the fifteen patients met a prerequisite for enrollment in our Phase 3 EYEGUARD-A study, a vitreous haze score of greater than or equal to two on the NEI/SUN scale. Eight of these eleven patients showed a two-unit reduction in vitreous haze at about day 70.

We believe positive results from both Servier’s and our Phase 2 Behçet’s uveitis studies, combined with positive data from EYEGUARD-B, could support a Behçet’s uveitis BLA submission. The FDA expects clinical evidence of activity in U.S. patients with Behçet’s uveitis to support a BLA filing in this indication. We are developing the protocol for this additional study, which would be used to supplement potential positive data from  EYEGUARD-B study and form the basis of a BLA filing for Behçet’s uveitis in the United States.

·

Continue to assess gevokizumab’s ability to treat a variety of diseases that have IL-1β involvement. We believe that by targeting IL-1 beta, gevokizumab has the potential to address the underlying inflammatory causes of a wide range of diseases.   We designed our POC program to study gevokizumab’s potential in diseases that have IL-1β involvement and that are recognized as those with unmet medical needs.  This program is structured in such a way that the success or failure of a single study does not have an impact on the other indications we are studying.

We are continuing our open-label safety and efficacy study gevokizumab in patients with EOA, as our analysis may determine that patients benefit from longer-term therapy or identify a subset of the patient population that could benefit from gevokizumab treatment.  This study, Study 161, has over 240 patients enrolled who are receiving gevokizumab 60 mg once monthly.

In April 2013, the NEI, one of the institutes of the NIH, opened its non-infectious, active, anterior scleritis trial for patient enrollment. The open-label single-arm Phase 1/2 study is designed to assess the safety and potential efficacy of gevokizumab in 10 patients experiencing non-infectious, active, anterior scleritis, which is the inflammation of the sclera (the fibrous white membrane surrounding the eyeball excluding the cornea).

In August 2013, we announced a single-center clinical trial in ten patients with AIED, which falls under the umbrella of sensorineural hearing loss. Patients with AIED usually experience multiple episodes of rapid hearing loss either concurrently or sequentially in both ears. This study is being run by the Feinstein Institute for Medical Research, Hearing & Speech Center at North Shore-Long Island Jewish Health System in collaboration with, and with funding from, the NIDCD and the NIH.

·

Establish commercial-scale manufacturing for gevokizumab . In August 2012, Servier and we announced an agreement with Boehringer Ingelheim to transfer XOMA's technology and processes for the validation of our technology and processes in preparation for the commercial manufacture of gevokizumab. Boehringer Ingelheim has completed GMP runs with successful biological comparability including all process validation batches of the XOMA processes. Boehringer Ingelheim is making preparations for the production of gevokizumab commercial batches at its facility in Biberach, Germany.

 

·

Advance our proprietary preclinical pipeline candidates and generate revenues from our proprietary technologies. We will continue to develop our proprietary preclinical pipeline, primarily focusing on the development of allosteric modulating monoclonal antibodies. Our most advanced program, which targets the insulin receptor, has generated three new classes of fully human monoclonal antibodies known as Selective Insulin Receptor Modulators (“SIRMs”). These allosteric modulating antibodies activate (“XMet A”), sensitize (“XMet S”) or deactivate/antagonize (“XOMA 247”) the insulin receptor in vivo . XMet A and XMet S represent the potential for distinct, new therapeutic approaches for the treatment of patients with diabetes. Separate studies of XMet A and XMet S have demonstrated reduced fasting blood glucose levels and improved glucose tolerance in mouse models of diabetes. We expect to out license XMet A and XMet S development and commercialization at a future date.

In the case of XOMA 247, a fully human, allosteric modulating monoclonal antibody engineered to deactivate the insulin receptor, we plan to develop this compound internally, as it has the potential to treat a variety of rare, severely debilitating diseases including congenital hyperinsulinism (“CHI”), hyperinsulinemic hypoglycemia in post-gastric bypass surgery patients and insulinomas.. In preclinical models, XOMA 247 has emulated the glucose lowering seen in patients with insulinomas, a beta cell tumor that over secretes insulin, and with CHI, a hereditary disease resulting in lack of insulin regulation and profound hypoglycemia that can result in seizures and brain damage. These models demonstrated XOMA 247 was capable of restoring fasting blood glucose to normal levels. We anticipate filing an IND for endogenous hypoglycemia in 2014.

Complete current biodefense contracts. To date, we have been awarded four contracts totaling approximately $120 million from NIAID to support development of XOMA 3AB and several additional product candidates for the treatment of botulism poisoning with botulinum toxin serotypes A, B and E, as well as C and D. In addition, our biodefense programs included two subcontracts from SRI International totaling $4.3 million, funded through NIAID, for the development of antibodies to neutralize H1N1 and H5N1 influenza viruses and the virus that causes severe acute respiratory syndrome (“SARS”).

NIAID has completed a Phase 1 trial of XOMA 3AB, a novel formulation of three antibodies designed to prevent and treat botulism poisoning from serotype A. This double-blind, dose-escalation study in 24 healthy volunteers was designed to assess the safety and tolerability and determine the pharmacokinetic profile of XOMA 3AB. This trial has been completed, and no drug product-related Serious Adverse Events have been observed. The results of this trial strongly support our platform approach for the remaining serotype-directed anti-toxins.

In 2012, we announced we will complete NIAID biodefense contracts currently in place but will not actively pursue future contracts. If the government chooses to acquire XOMA 3AB or other biodefense products in the future, we expect to be able to provide these antibodies through an outside manufacturer.

Proprietary Products

As part of our strategy, we are focusing our technology and resources on advancing our emerging proprietary pipeline. Below is a summary of our proprietary products:

·

Gevokizumab is a proprietary potent humanized monoclonal antibody with unique allosteric modulating properties and has the potential to treat patients with a wide variety of inflammatory diseases..   Gevokizumab binds strongly to IL-1 beta, a pro-inflammatory cytokine involved in NIU and Behçet’s uveitis, PG, active non-infectious anterior scleritis, cardiovascular disease, diseases under the neutrophilic dermatoses designation, Schnitzler syndrome and other diseases.. By binding to IL-1 beta, gevokizumab modulates the activation of the IL-1 receptor, thereby preventing the cellular signaling events that produce inflammation Based on its binding properties, specificity for IL-1 beta and its half-life (the time it takes for the amount administered to be reduced by one-half) in the body, gevokizumab may provide convenient dosing of once per month or less frequently.

In December 2010, we entered into an agreement with Servier to jointly develop and commercialize gevokizumab in multiple indications. Under the terms of that agreement, Servier has worldwide rights to gevokizumab for cardiovascular disease and diabetes indications and rights outside the United States and Japan to all other indications. We retain development and commercialization rights in the United States and Japan to all indications except cardiovascular disease and diabetes and have an option to reacquire rights to these indications from Servier in these territories. In 2012, Servier initiated a gevokizumab Phase 2 study in patients with acute coronary syndrome, a cardiovascular disease. In 2013, Servier also began testing gevokizumab in a variety of proof-of-concept studies, including polymyositis/dermatomyositis, Schnitzler syndrome, and giant cell arteritis.

·

XMet:  XOMA Metabolic Activating, Sensitizing and Antagonizing/Deactivating Antibodies.   “SIRMs, such as XMet A, are designed to provide long-acting insulin-like activity to diabetic patients who cannot make sufficient insulin, potentially reducing the number of insulin injections needed to control their blood glucose levels.  Insulin receptor-sensitizing antibodies, such as XMet S, are designed to reduce insulin resistance and could enable diabetic patients to use their own insulin more effectively to control blood glucose levels. Insulin receptor deactivating/antagonizing antibodies, such as XOMA 247, are designed to treat several diseases that result from the continuous over-production of or inappropriate reaction to insulin. There are three rare disease indications that may benefit from XOMA 247 that are of greatest interest to us: congenital hyperinsulinism (“CHI”), hyperinsulinemic hypoglycemia in post-gastric bypass surgery patients and insulinomas.

Studies presented on XMet A have demonstrated it reduced fasting blood glucose levels and improved glucose tolerance in a mouse model of diabetes. After six weeks of treatment, mice treated with XMet A had a statistically significant reduction in HbA1c levels, a standard measure of average blood glucose levels over time, compared to the control mice. In addition, there was a statistically significant reduction in elevated non-high-density lipoprotein cholesterol levels.

Studies presented on XMet S have indicated that it is an allosteric antibody that binds to the insulin receptor (“INSR”) and enhances the binding of insulin to the INSR. In diabetic mouse models, we saw enhanced insulin sensitivity and statistically significant improvements in fasting blood glucose levels and glucose tolerance as compared to the control mice.

XOMA 3AB is a multi-antibody product designed to neutralize the most potent of the botulinum toxins, Type A, which causes paralysis and is a bioterrorism threat.  Our anti-botulism program also includes additional product candidates and is the first of its kind to combine multiple human antibodies in each product candidate to target a broad spectrum of the most toxic botulinum toxins, including the three most toxic serotypes, Types A, B and E.  The antibodies are designed to bind to each toxin and enhance the clearance of the toxin from the body.  The use of multiple antibodies increases the likelihood of clearing the harmful toxins by providing specific protection against each toxin type.  In contrast to existing agents that treat botulism, XOMA uses advanced human monoclonal antibody technologies in an effort to achieve superior safety, potency and efficacy and avoid life-threatening immune reactions associated with animal-derived products. NIAID has completed a Phase 1 trial of XOMA 3AB.

·

XOMA 629 is a topical anti-bacterial formulation of a peptide derived from bactericidal/permeability-increasing protein (“BPI”), an integral part of the protective human immune system. In 2012, XOMA entered into a license agreement with Margaux Biologics, Inc. (“Margaux”), under which XOMA transferred its rights, title, and interest in BPI. As consideration for the transferred assets and licenses, Margaux issued shares of its common stock to XOMA, representing an amount of capital stock equal to 7% of the outstanding capital stock of Margaux. Under the terms of this agreement, we may receive milestone payments aggregating up to $5.6 million and low- to mid-single-digit royalties on future sales of products subject to this license.

 

·

Preclinical Product Pipeline:   We are pursuing additional opportunities to further broaden our preclinical product pipeline, including internal discovery programs.

Partnership Products

Historically, we have provided research and development collaboration services for world-class organizations, such as Novartis and Takeda, in pursuit of new antibody products.  In more recent years, we have evolved our business focus from a service provider model to a proprietary product development model. However, we will continue to capitalize on partnered product arrangements as opportunities arise. Below is a list of such partnerships:

·

Therapeutic Antibodies with Takeda: Since 2006, Takeda has been a collaboration partner for therapeutic monoclonal antibody discovery and development against multiple targets selected by them.  In February 2009, we expanded our existing collaboration to provide Takeda with access to multiple antibody technologies, including a suite of research and development technologies and integrated information and data management systems.  We may receive potential milestones and royalties on sales of antibody products in the future.

·

Therapeutic Antibodies with Novartis: In November 2008, we restructured our product development collaboration with Novartis, which was entered into in 2004 with Novartis (then Chiron Corporation).  Under the restructured agreement, Novartis received control over the two ongoing programs. We may, in the future, receive milestones and/or double-digit royalty rates for the programs and options to develop or receive royalties from four additional programs.

Technologies

We have a unique set of antibody discovery, optimization and development technologies, including:

·

ADAPT™ (Antibody Discovery Advanced Platform Technologies): proprietary phage display libraries integrated with yeast and mammalian display to enable antibody discovery;

·

ModulX™: technology that enables positive and negative modulation of biological pathways using allosterically modulating antibodies; and

·

OptimX™: technologies used for optimizing biophysical properties of antibodies, including affinity, immunogenicity, stability and manufacturability.

Technology Licenses

Below is a summary of certain proprietary technologies owned by us and available for licensing to other companies:

·

Antibody Discovery Technologies: We use human antibody phage display libraries, integrated with yeast and mammalian display, which we call ADAPT™ Integrated Display, in our discovery of therapeutic candidates. We offer access to this platform, including novel phage libraries developed internally, as part of our collaboration business.  We believe access to ADAPT™ Integrated Display offers a number of benefits to us and our collaboration partners because it enables us to combine the diversity of phage libraries with accelerated discovery due to rapid IgG reformatting and FACS-based screening using yeast and mammalian display. This increases the probability of technical and business success in finding rare and unique functional antibodies directed to targets of interest.

·

ModulX™ technology: ModulX™ technology allows modulation of biological pathways using monoclonal antibodies and offers insights into regulation of signaling pathways, homeostatic control, and disease biology. Using ModulX™, XOMA is generating product candidates with novel mechanisms of action that specifically alter the kinetics of interaction between molecular constituents (e.g. receptor-ligand). ModulX™ technology enables expanded target and therapeutic options and offers a unique approach in the treatment of disease.

·

OptimX™ technologies:

Human Engineering™ (“HE™”): HE™ is a proprietary humanization technology that allows modification of non-human monoclonal antibodies to reduce or eliminate detectable immunogenicity and make them suitable for medical purposes in humans.  The technology uses a unique method developed by us, based on analysis of the conserved structure-function relationships among antibodies.  The method defines which residues in a non-human variable region are candidates to be modified.  The result is an HE™ antibody with preserved antigen binding, structure and function that has eliminated or greatly reduced immunogenicity.  HE™ technology was used in development of gevokizumab and is used in the development of certain other antibody products.

Targeted Affinity Enhancement™ (“TAE™”): TAE™ is a proprietary technology involving the assessment and guided substitution of amino acids in antibody variable regions, enabling efficient optimization of antibody binding affinity and selectivity modulation.  TAE™ generates a comprehensive map of the effects of amino acid mutations in the CDR region likely to impact binding.  The technology is utilized by XOMA scientists and has been licensed to a number of our collaborators.

Financial and Legal Arrangements of Product Collaborations, Licensing and Other Arrangements

Collaboration and Licensing Agreements

Servier -- Gevokizumab

We have entered into a license and collaboration agreement with Servier to jointly develop and commercialize gevokizumab in multiple indications that provided a non-refundable upfront payment of $15 million, which we received in January 2011.  Under the terms of the agreement, Servier has worldwide rights to cardiovascular disease and diabetes indications and rights outside the United States and Japan to all other indications, including NIU, Behçet’s uveitis and other inflammatory and oncology indications. XOMA retains development and commercialization rights in the United States and Japan for all indications other than cardiovascular disease and diabetes.  XOMA has an option to reacquire rights to cardiovascular disease and diabetes indications from Servier in the United States and Japan (the “Cardiometabolic Indications Option”).  If we exercise the Cardiometabolic Indications Option, we will be required to pay Servier an option fee and partially reimburse their incurred development expenses.  Each party has the right in certain circumstances to pursue development in indications not specified in the agreement, and in such event, the other party will have the option to participate in such development in certain circumstances, including reimbursement of a portion of the developing party’s expenses.

Under this agreement, Servier will fund all activities to advance the global clinical development and future commercialization of gevokizumab in cardiovascular-related diseases and diabetes.  Also, Servier funded the first $50 million of gevokizumab global clinical development and CMC expenses and continues to fund 50% of further expenses related to the NIU and Behçet’s uveitis indications.

In addition, under the agreement, we are eligible to receive a combination of Euro- and U.S. Dollar (“USD”)-denominated, development and sales milestones for multiple indications aggregating to a potential maximum of approximately $488 million when converted using the December 31, 2013, Euro to USD exchange rate (the “12/31/13 Exchange Rate of 1.3766”), if XOMA reacquires cardiovascular and/or diabetes rights for use in the United States and Japan. If XOMA does not reacquire these rights, then the milestone payments aggregate to a potential maximum of approximately $827 million converted using the 12/31/13 Exchange Rate of 1.3766. Servier’s obligation to pay development and commercialization milestones will continue for so long as Servier is developing or selling products under the agreement.

We are eligible to receive royalties on gevokizumab sales from sales outside of the United States and Japan, and from global sales in cardio-metabolic indications, that are tiered based on sales levels and range from a mid-single digit to up to a mid-teens percentage rate.  Our right to royalties with respect to a particular product and country will continue for so long as such product is sold in such country.

The collaboration is carried out and managed by committees mutually established by XOMA and Servier.  In general, in the event of any disputes, each party has decision-making authority over matters relating to its areas of responsibility and territory, but neither party has unilateral decision-making rights if the decision would have a material adverse impact on the other party’s rights in its territory.  The agreement contains customary termination rights relating to matters such as material breach by either party, safety issues and patents.  Servier also has a unilateral right to terminate the agreement on a country-by-country basis or in its entirety on six months’ notice.

We also entered into a loan agreement with Servier (the “Servier Loan Agreement”) that provided for an advance of up to €15.0 million. The loan was fully funded in January 2011, with the proceeds converting to approximately $19.5 million at the date of funding. The loan is secured by an interest in XOMA’s intellectual property rights to all gevokizumab indications worldwide, excluding certain rights in the United States and Japan. Interest is calculated at a floating rate based on a Euro Inter-Bank Offered Rate (“EURIBOR”) and is subject to a cap. The interest rate is reset semi-annually in January and July of each year. The interest rate for the initial interest period was 3.22% and was reset semi-annually ranging from 2.33% to 3.83%. Interest for the six-month period from January 2014 through July 2014 was reset to 2.39%. Interest is payable semi-annually; however, the Servier Loan Agreement provides for a deferral of interest payments over a period specified in the agreement. During the deferral period, accrued interest will be added to the outstanding principal amount for the purpose of interest calculation for the next six-month interest period. On the repayment commencement date, all unpaid and accrued interest shall be paid to Servier, and thereafter, all accrued and unpaid interest shall be due and payable at the end of each six-month period. In January 2014, the Company paid $1.9 million in accrued interest to Servier.

The loan matures in 2016; however, after a specified period prior to final maturity, the loan is to be repaid (i) at Servier's option, by applying up to a significant percentage of any milestone or royalty payments owed by Servier under our collaboration agreement and (ii) using a significant percentage of any upfront, milestone or royalty payments we receive from any third-party collaboration or development partner for rights to gevokizumab in the United States and/or Japan. In addition, the loan becomes immediately due and payable upon certain customary events of default. At December 31, 2013, the outstanding principal balance under this loan was $20.6 million using the 12/31/13 Exchange Rate of 1.3766.  Refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations for further information regarding the Servier Loan Agreement.

NIAID

In September 2008, we were awarded a third NIAID contract for $64.8 million under Contract No. HHSN272200800028C (“NIAID 3”) to continue development of our anti-botulinum antibody product candidates, including XOMA 3AB and additional product candidates directed against the B and E toxin serotypes.  As part of the contract, we have developed, evaluated and produced the clinical supplies to support an IND filing with the FDA for XOMA 3AB. Independently, XOMA has funded preclinical studies required to support human clinical trials. A Phase 1 trial was completed on XOMA 3AB, with no product-related serious adverse events.  Subsequently, XOMA manufactured XOMA 3B and XOMA 3E, which are currently on stability.

In October 2011, we announced we had been awarded a fourth NIAID contract for up to $28.0 million over five years under Contract No. HHSN 272201100031C (“NIAID 4”) to develop broad-spectrum antitoxins for the treatment of human botulism poisoning.

In January 2012, we announced we will complete NIAID biodefense contracts currently in place but will not actively pursue future contracts. Should the government choose to acquire XOMA 3AB or other biodefense products in the future, we expect to be able to provide these antibodies through an outside manufacturer.

Takeda

In November 2006, we entered into a fully funded collaboration agreement with Takeda for therapeutic monoclonal antibody discovery and development activities under which we agreed to discover and optimize therapeutic antibodies against multiple targets selected by Takeda.  Takeda agreed to make up-front, annual maintenance and milestone payments to us, fund our research and development and manufacturing activities for preclinical and early clinical studies and pay royalties on sales of products resulting from the collaboration.  Takeda is responsible for clinical trials and commercialization of drugs after an IND submission and is granted the right to manufacture once a product enters into Phase 2 clinical trials.  We have completed a technology transfer and do not expect to perform any further research and development services under this program. From 2011 through 2013, we received milestone payments relating to one currently active program.

Under the terms of this agreement, we may receive milestone payments aggregating up to $19.0 million relating to one undisclosed product candidate and low single-digit royalties on future sales of all products subject to this license.  In addition, in the event Takeda were to develop additional future qualifying product candidates under the terms of our agreement, we would be eligible for milestone payments aggregating up to $20.75 million for each such qualifying product candidate.  Our right to milestone payments expires on the later of the receipt of payment from Takeda of the last amount to be paid under the agreement or the cessation by Takeda of all research and development activities with respect to all program antibodies, collaboration targets and/or collaboration products.  Our right to royalties expires on the later of 13.5 years from the first commercial sale of each royalty-bearing discovery product or the expiration of the last-to-expire licensed patent.

In February 2009, we expanded our existing collaboration to provide Takeda with access to multiple antibody technologies, including a suite of research and development technologies and integrated information and data management systems.  We may receive milestones of up to $3.25 million per discovery product candidate and low single-digit royalties on future sales of all antibody products subject to this license.  Our right to milestone payments expires on the later of the receipt of payment from Takeda of the last amount to be paid under the agreement or the cessation by Takeda of all research and development activities with respect to all program antibodies, collaboration targets and/or collaboration products.  Our right to royalties expires on the later of 10 years from the first commercial sale of such royalty-bearing discovery product or the expiration of the last-to-expire licensed patent.

Novartis

In November 2008, we restructured our product development collaboration with Novartis. Under the restructured agreement, Novartis made a payment to us of $6.2 million in cash and reduced our existing debt by $7.5 million; will fund all future research and development expenses; may pay potential milestones of up to $14.0 million and royalty rates ranging from low-double digit to high-teen percentage rates for two ongoing product programs, HCD122 and LFA102; and has provided us with options to develop or receive royalties on four additional programs. In exchange, Novartis has control over the HCD122 and LFA102 programs, as well as the right to expand the development of these programs into additional indications outside of oncology. In 2013, we received a $7.0 million milestone relating to one currently active program. Our right to milestone payments expires at such time as no collaboration product or former collaboration product is being developed or commercialized anywhere in the world and no royalty payments on these products are due.  Our right to royalty payments expires on the later of the expiration of any licensed patent covering each product or 20 years from the launch of each product.

In connection with the collaboration between XOMA and Novartis (then Chiron Corporation), a secured note agreement was executed in May 2005.  The note agreement is secured by our interest in the collaboration and is due and payable in full in June 2015.  At December 31, 2013, the outstanding principal balance under this note agreement totaled $14.8 million, and pursuant to the terms of the arrangement as restructured in November 2008, we will not make any additional borrowings on the Novartis note. Pursuant to our obligations under the Agreement, in January 2014, we made a payment, equal to 25 percent of a $7.0 million milestone received, or $1.75 million, toward our outstanding debt obligation to Novartis.

Pfizer

In August 2007, we entered into a license agreement with Pfizer Inc. (“Pfizer”) for non-exclusive, worldwide rights for XOMA’s patented bacterial cell expression technology for research, development and manufacturing of antibody products. Under the terms of the agreement, we received a license fee payment of $30 million in 2007.

Table of Contents

From 2011 through 2013, we received milestone payments relating to ten undisclosed product candidates. We may also be eligible for additional milestone payments aggregating up to $15.2 million relating to twelve product candidates and low single-digit royalties on future sales of all products subject to this license. In addition, we may receive potential milestone payments aggregating up to $1.7 million for each additional qualifying product candidate. Our right to milestone payments expires on the later of the expiration of the last-to-expire licensed patent or the tenth anniversary of the effective date. Our right to royalties expires upon the expiration of the last-to-expire licensed patent.  We expect recognize ant revenue on milestones when and if they are achieved and on royalties when and if the underlying sales occur.

Financing Agreements

Outstanding Warrants

In June of 2009, we issued warrants to certain institutional investors as part of a registered direct offering, which represent the right to acquire an aggregate of up to 347,826 shares of common stock over a five-year period beginning December 11, 2009, at an exercise price of $19.50 per share. As of December 31, 2013, all of these warrants were outstanding.

In February 2010, we issued warrants to purchase 1,260,000 shares of XOMA’s common stock in connection with an underwritten offering, which were exercisable beginning six months and one day after issuance and have a five-year term and an exercise price of $10.50 per share. As of December 31, 2013, all of these warrants were outstanding.

In December 2011, we issued warrants in connection with a debt financing, which entitle the holder to purchase up to an aggregate of 263,158 unregistered shares of XOMA common stock at an exercise price equal to $1.14 per share. The warrants are exercisable immediately and will expire on December 30, 2016. As of December 31, 2013, all of these warrants were outstanding.

In March 2012, we issued warrants in connection with an underwritten public offering, which entitle the holders to purchase up to an aggregate of 14,834,577 shares of XOMA common stock at an exercise price equal to $1.76 per share. The warrants are exercisable immediately and will expire on March 6, 2017. As of December 31, 2013, 12,562,682 of these warrants were outstanding.

In September 2012, we issued warrants in connection with an amendment to an existing debt financing, which entitle the holder to purchase up to an aggregate of 39,346 unregistered shares of XOMA common stock at an exercise price equal to $3.54 per share. The warrants are exercisable immediately and will expire on September 27, 2017. As of December 31, 2013, all of these warrants were outstanding.

ATM Agreement

On February 4, 2011, we entered into an At Market Issuance Sales Agreement (the “2011 ATM Agreement”), with McNicoll, Lewis & Vlak LLC (now known as MLV & Co. LLC, “MLV”), under which we may sell shares of our common stock from time to time through MLV, as our agent for the offer and sale of the shares, in an aggregate amount not to exceed the amount that can be sold under our registration statement on Form S-3 (File No. 333-172197) filed with the SEC on February 11, 2011, and amended on March 10, 2011, June 3, 2011 and January 3, 2012, which was most recently declared effective by the SEC on January 17, 2012.  MLV may sell the shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act, including without limitation sales made directly on The NASDAQ Global Market, on any other existing trading market for our common stock or to or through a market maker.  MLV also may sell the shares in privately negotiated transactions, subject to our prior approval.  We will pay MLV a commission equal to 3% of the gross proceeds of the sales price of all shares sold through it as sales agent under the 2011 ATM Agreement.  From the inception of the 2011 ATM Agreement through December 31, 2012, we sold a total of 7,572,327 shares of common stock under this agreement for aggregate gross proceeds of $14.6 million.  No shares of common stock have been sold under this agreement since February 3, 2012. Total offering expenses incurred related to sales under the 2011 ATM Agreement from inception to December 31, 2013, were $0.5 million. The registration statement under which the 2011 ATM was entered expires in June of 2014.

General Electric Capital Corporation Term Loan

In December 2011, we entered into a loan agreement (the “GECC Loan Agreement”) with General Electric Capital Corporation (“GECC”), under which GECC agreed to make a term loan in an aggregate principal amount of $10 million (the “Term Loan”) to us, and upon execution of the GECC Loan Agreement, GECC funded the Term Loan. As security for our obligations under the GECC Loan Agreement, we granted a security interest in substantially all of our existing and after-acquired assets, excluding its intellectual property assets (such as those relating to our gevokizumab and anti-botulism products). The Term Loan accrued interest at a fixed rate of 11.71% per annum and was to be repaid over a period of 42 consecutive equal monthly installments of principal and accrued interest and was due and payable in full on June 15, 2015. We incurred debt issuance costs of approximately $1.3 million in connection with the Term Loan and were required to pay a final payment fee equal to $500,000 on the maturity date, or such earlier date as the Term Loan is paid in full. The debt issuance costs and final payment fee were being amortized and accreted, respectively, to interest expense over the term of the Term Loan using the effective interest method.

Table of Contents

In connection with the GECC Loan Agreement, we issued to GECC unregistered warrants that entitle GECC to purchase up to an aggregate of 263,158 unregistered shares of XOMA common stock at an exercise price equal to $1.14 per share. These warrants are exercisable immediately and have a five-year term. We allocated the aggregate proceeds of the GECC Term Loan between the warrants and the debt obligation based on their relative fair values.  The fair value of the warrants issued to GECC was determined using the Black-Scholes Model. The warrants’ fair value of $0.2 million was recorded as a discount to the debt obligation and was being amortized over the term of the loan using the effective interest method.

In September 2012, we entered into an amendment to the GECC Loan Agreement providing for an additional term loan in the amount of $4.6 million, increasing the term loan obligation to $12.5 million (the “Amended Term Loan”) and providing for an interest-only monthly repayment period following the effective date of the amendment through March 1, 2013, at a stated interest rate of 10.9% per annum. Thereafter, we are obligated to make monthly principal payments of $347,222, plus accrued interest, over a 27-month period commencing on April 1, 2013, and through June 15, 2015, at which time the remaining outstanding principal amount of $3.1 million, plus accrued interest, is due.  We incurred debt issuance costs of approximately $0.2 million and are required to make a final payment fee in the amount of $875,000 on the date upon which the outstanding principal amount is required to be repaid in full.  This final payment fee replaced the original final payment fee of $500,000. The debt issuance costs and final payment fee are being amortized and accreted, respectively, to interest expense over the term of the Amended Term Loan using the effective interest method.

In connection with the amendment, on September 27, 2012, we issued to GECC unregistered stock purchase warrants, which entitle GECC to purchase up to an aggregate of 39,346 shares of XOMA common stock at an exercise price equal to $3.54 per share. These warrants are exercisable immediately and have a five-year term. The warrants’ fair value of $0.1 million was recorded as a discount to the debt obligation and is being amortized over the term of the loan using the effective interest method. The warrants are classified in permanent equity on the consolidated balance sheets.

The Amended Term Loan does not change the remaining terms of the GECC Loan Agreement. The GECC Loan Agreement contains customary representations and warranties and customary affirmative and negative covenants, including restrictions on the ability to incur indebtedness, grant liens, make investments, dispose of assets, enter into transactions with affiliates and amend existing material agreements, in each case subject to various exceptions. In addition, the GECC Loan Agreement contains customary events of default that entitle GECC to cause any or all of the indebtedness under the GECC Loan Agreement to become immediately due and payable. The events of default include any event of default under a material agreement or certain other indebtedness.

We may prepay the Amended Term Loan voluntarily in full, but not in part, and any voluntary and certain mandatory prepayments are subject to a prepayment premium of 3% in the first year after the effective date of the amendment to the GECC Loan Agreement, 2% in the second year and 1% thereafter, with certain exceptions.  We will also be required to pay the $875,000 final payment fee in connection with any voluntary or mandatory prepayment. On the effective date of the amendment to the GECC Loan Agreement, we paid an accrued final payment fee in the amount of $0.2 million relating to the original final payment fee of $500,000.

At December 31, 2013, the outstanding principal balance under the Amended Term Loan was $9.4 million.

Underwritten Offerings

On March 9, 2012, we completed an underwritten public offering of 29,669,154 shares of our common stock, and accompanying warrants to purchase one half of a share of common stock for each share purchased, at a public offering price of $1.32 per share. Total gross proceeds from the offering were approximately $39.2 million, before deducting underwriting discounts and commissions and estimated offering expenses totaling approximately $3.0 million. The warrants, which represent the right to acquire an aggregate of up to 14,834,577 shares of common stock, are exercisable immediately and have a five-year term and an exercise price of $1.76 per share. As of December 31, 2013, 12,562,682 of these warrants were outstanding.

Total gross proceeds from the offering were approximately $57.4 million, before deducting underwriting discounts and commissions and estimated offering expenses totaling approximately $3.8 million.

Research and Development

Our research and development expenses currently include costs of personnel, supplies, facilities and equipment, consultants, third-party costs and other expenses related to preclinical and clinical testing.  In 2013, our research and development expenses were $74.9 million, compared with $68.5 million in 2012 and $68.1 million in 2011.

Our research and development activities can be divided into those related to our internal projects and those related to collaborative and contract arrangements, which are reimbursed by our customers.  In 2013, research and development expenses relating to internal projects were $47.5 million, compared with $30.5 million in 2012 and $24.4 million in 2011.  In 2013, research and development expenses related to collaborative and contract arrangements were $27.4 million, compared with $37.9 million in 2012 and $43.7 million in 2011.  Refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations- Research and Development Expenses for further information regarding our research and development expenses.

Competition

The biotechnology and pharmaceutical industries are subject to continuous and substantial technological change.  Competition in antibody-based technologies is intense and is expected to increase as new technologies emerge and established biotechnology firms and large chemical and pharmaceutical companies continue to advance in the field.  A number of these large pharmaceutical and chemical companies have enhanced their capabilities by entering into arrangements with or acquiring biotechnology companies or entering into business combinations with other large pharmaceutical companies.  Many of these companies have significantly greater financial resources, larger research and development and marketing staffs and larger production facilities than ours.  Moreover, certain of these companies have extensive experience in undertaking preclinical testing and human clinical trials.  These factors may enable other companies to develop products and processes competitive with or superior to ours.  In addition, a significant amount of research in biotechnology is being carried out in universities and other non-profit research organizations.  These entities are becoming increasingly interested in the commercial value of their work and may become more aggressive in seeking patent protection and licensing arrangements.  Furthermore, many companies and universities tend not to announce or disclose important discoveries or development programs until their patent position is secure or, for other reasons, later.  As a result, we may not be able to track development of competitive products, particularly at the early stages.  There can be no assurance that developments by others will not render our products or technologies obsolete or uncompetitive.

Without limiting the foregoing, we are aware of the following competitors for the products and candidates shown in the table below.  This table is not intended to be representative of all existing competitors in the market:

Government Regulation

The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the clinical development, pre-market approval, manufacture, marketing, import, export and distribution of biopharmaceutical products. These agencies and other regulatory agencies regulate research and development activities and the testing, approval, manufacture, quality control, safety, effectiveness, labeling, storage, recordkeeping, advertising and promotion of products and product candidates. Failure to comply with applicable FDA or other regulatory requirements may result in Warning Letters, civil or criminal penalties, suspension or delays in clinical development, recall or seizure of products, partial or total suspension of production or withdrawal of a product from the market. The development and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our product candidates will be granted on a timely basis, if at all. We must obtain approval of our product candidates from the FDA before we can begin marketing them in the United States. Similar approvals are also required in other countries.

 

Product development and approval within this regulatory framework is uncertain, can take many years and requires the expenditure of substantial resources. The nature and extent of the governmental review process for our product candidates will vary, depending on the regulatory categorization of particular product candidates and various other factors.

 

The necessary steps before a new biopharmaceutical product may be sold in the United States ordinarily include:

 

●

preclinical in vitro and in vivo tests, which must comply with Good Laboratory Practices, or GLP;

 

●

submission to the FDA of an IND which must become effective before clinical trials may commence, and which must be updated annually with a report on development;

 

●

completion of adequate and well controlled human clinical trials to establish the safety and efficacy of the product candidate for its intended use;

 

●

submission to the FDA of a Biologics License Application, or BLA, which must often be accompanied by payment of a substantial user fee;

 

●

FDA pre-approval inspection of manufacturing facilities for current Good Manufacturing Practices, or GMP, compliance and FDA inspection of select clinical trial sites for Good Clinical Practice, or GCP, compliance; and

 

●

FDA review and approval of the BLA and product prescribing information prior to any commercial sale.

 

The results of preclinical tests (which include laboratory evaluation as well as preclinical GLP studies to evaluate toxicity) for a particular product candidate, together with related manufacturing information and analytical data, are submitted as part of an IND to the FDA. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions about the conduct of the clinical trial, including concerns that human research subjects will be exposed to unreasonable health risks. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. IND submissions may not result in FDA authorization to commence a clinical trial. A separate submission to an existing IND must also be made for each successive clinical trial conducted during product development. Further, an independent institutional review board, or IRB, for each medical center proposing to conduct the clinical trial must review and approve the plan for any clinical trial before it commences at that center and it must monitor the study until completed. The FDA, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Clinical testing also must satisfy extensive GCP regulations and regulations for informed consent and privacy of individually identifiable information.

Table of Contents

Clinical trials generally are conducted in three sequential phases that may overlap or in some instances, be skipped. In Phase 1, the initial introduction of the product into humans, the product is tested to assess safety, metabolism, pharmacokinetics and pharmacological actions associated with increasing doses. Phase 2 usually involves trials in a limited patient population to evaluate the efficacy of the potential product for specific, targeted indications, determine dosage tolerance and optimum dosage and further identify possible adverse reactions and safety risks. Phase 3 and pivotal trials are undertaken to evaluate further clinical efficacy and safety often in comparison to standard therapies within a broader patient population, generally at geographically dispersed clinical sites. Phase 4, or post-marketing, trials may be required as a condition of commercial approval by the FDA and may also be voluntarily initiated by us or our collaborators. Phase 1, Phase 2 or Phase 3 testing may not be completed within any specific period of time, if at all, with respect to any of our product candidates. Similarly, suggestions of safety, tolerability or efficacy in earlier-stage trials do not necessarily predict findings of safety and effectiveness in subsequent trials. Furthermore, the FDA, an IRB or we may suspend a clinical trial at any time for various reasons, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Clinical trials are subject to central registration and results reporting requirements, such as on www.clinicaltrials.gov.

 

The results of preclinical studies, pharmaceutical development and clinical trials, together with information on a product’s chemistry, manufacturing, and controls, are submitted to the FDA in the form of a BLA, for approval of the manufacture, marketing and commercial shipment of the biopharmaceutical product. Data from clinical trials are not always conclusive and the FDA may interpret data differently than we or our collaborators interpret data. For all compounds seeking their first marketing approval, the FDA convenes an Advisory Committee of external advisors to answer questions regarding the compound’s approvability and what labeling the compound should receive based upon its NDA or BLA. Approved compounds seeking to expand their label may also be the subject of an Advisory Committee depending upon the indication. The FDA may also convene an Advisory Committee of external advisors to answer questions regarding the approvability and labeling of an application. The FDA is not obligated to follow the Advisory Committee’s recommendation. The submission of a BLA is required to be accompanied by a substantial user fee, with few exceptions or waivers. The user fee is administered under the Prescription Drug User Fee Act, or PDUFA, which sets goals for the timeliness of the FDA’s review. A standard review period is twelve months from submission of the application, while priority review is eight months from submission of the application. The testing and approval process is likely to require substantial time, effort and resources, and there can be no assurance that any approval will be granted on a timely basis, if at all. The FDA may deny review of an application by refusing to file the application or not approve an application by issuance of a complete response letter if applicable regulatory criteria are not satisfied, require additional testing or information, or require risk management programs and post-market testing and surveillance to monitor the safety or efficacy of the product. Approval may occur with significant Risk Evaluation and Mitigation Strategies, or REMS, which limit the clinical use in the prescribing information, distribution or promotion of a product. Once issued, the FDA may withdraw product approval if ongoing regulatory requirements are not met or if safety problems occur after the product reaches the market.

Orphan drugs are those intended for use in rare diseases or conditions.  As a result of the high cost of development and the low return on investment for rare diseases, governments provide regulatory and commercial incentives for the development of drugs for small disease populations.  In the United States, the term ‘‘rare disease or condition’’ means any disease or condition that affects fewer than 200,000 persons in the United States.  Applications for U.S. orphan drug status are evaluated and granted by the Office of Orphan Products Development (“OOPD”) of the FDA and must be requested before submitting a BLA.  In the United States, orphan drugs are subject to the standard regulatory process for marketing approval but are exempt from the payment of user fees for licensure, may receive market exclusivity for a period of seven years and some tax benefits, and are eligible for OOPD grants.  If a product with orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan product exclusivity, which means the FDA may not approve any other applications to market the same drug or biological product for the same indication, except in very limited circumstances, for seven years. Competitors, however, may receive approval of different products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan product exclusivity also could block the approval of one of our products for seven years if a competitor obtains approval of the same drug or biological product as defined by the FDA or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease. If a drug or biological product designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan product exclusivity.

Products manufactured or distributed pursuant to FDA approvals are subject to continuing regulation by the FDA, including manufacture, labeling, advertising, distribution, advertising, promotion, recordkeeping, annual product quality review and reporting requirements. Adverse event experience with the product must be reported to the FDA in a timely fashion and pharmacovigilance programs to proactively look for these adverse events are mandated by the FDA. Manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with ongoing regulatory requirements, including cGMPs, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Following such inspections, the FDA may issue notices on Form 483 and Warning Letters that could cause us to modify certain activities. A Form 483 notice, if issued at the conclusion of an FDA inspection, can list conditions the FDA investigators believe may have violated cGMP or other FDA regulations or guidance. Failure to adequately and promptly correct the observations(s) can result in further regulatory enforcement action. In addition to Form 483 notices and Warning Letters, failure to comply with the statutory and regulatory requirements can subject a manufacturer to possible legal or regulatory action, such as suspension of manufacturing, seizure of product, injunctive action or possible civil penalties. We cannot be certain that we or our present or future third-party manufacturers or suppliers will be able to comply with the cGMP regulations and other ongoing FDA regulatory requirements. If we or our present or future third-party manufacturers or suppliers are not able to comply with these requirements, the FDA may halt our clinical trials, not approve our products, require us to recall a product from distribution or withdraw approval of the BLA for that product. Failure to comply with ongoing regulatory obligations can result in delay of approval or Warning Letters, product seizures, criminal penalties, and withdrawal of approved products, among other enforcement remedies.

 

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. These regulations include standards and restrictions for direct-to-consumer advertising, industry-sponsored scientific and educational activities, promotional activities involving the internet, and off-label promotion. While physicians may prescribe for off-label uses, manufacturers may only promote for the approved indications and in accordance with the provisions of the approved label. The FDA has very broad enforcement authority under the FDCA, and failure to abide by these regulations can result in penalties, including the issuance of a warning letter directing entities to correct deviations from FDA standards, and state and federal civil and criminal investigations and prosecutions.

 

Federal and state healthcare laws, including fraud and abuse and health information privacy and security laws, are also applicable to our business.  We could face substantial penalties and our business, results of operations, financial condition and prospects could be adversely affected.  The laws that may affect our ability to operate include: the federal Anti-Kickback Statute, which prohibits soliciting, receiving, offering or paying remuneration, directly or indirectly, to induce, or in return for, the purchase or recommendation of an item or service reimbursable under a federal healthcare program, such as the Medicare and Medicaid programs; federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payers that are false or fraudulent; and the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created new federal criminal statutes that prohibit executing a scheme to defraud any healthcare benefit program and making false statements relating to healthcare matters and was amended by the Health Information Technology and Clinical Health Act, or HITECH, and its implementing regulations, which imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information.  State law equivalents of each of the above federal laws exist, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

 

International Regulation

 

In addition to regulations in the United States, we are subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of any future products. Whether or not we obtain FDA approval for a product, we must obtain approval by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.

Patents and Trade Secrets

Patent and trade secret protection are important to our business and our future will depend in part on our ability to obtain patents, maintain trade secret protection and operate without infringing on the proprietary rights of others.  As a result of our ongoing activities, we hold and have filed applications for a number of patents in the United States and internationally to protect our products and important processes.  We also have obtained or have the right to obtain exclusive licenses to certain patents and applications filed by others.  However, the patent position of biotechnology companies generally is highly uncertain and consistent policy regarding the breadth of allowed claims has not emerged from the actions of the U.S. Patent and Trademark Office (“Patent Office”) with respect to biotechnology patents.  Accordingly, no assurance can be given that our patents will afford protection against competitors with similar technologies or others will not obtain patents claiming aspects similar to those covered by our patent applications.

In November 2013, we were awarded U.S. Patent No. 8,584,349, entitled "Flexible Manufacturing System." This patent is directed to a flexible system of movable manufacturing bays, adapted to easily and quickly connect to a central supply of utilities such as air, water, and electricity. This unique arrangement facilitates flexible design and eliminates change-over downtime, which translates into significantly reduced capital expenditures, production costs, and maintenance costs. The flexible manufacturing system can be applied to fields as diverse as pharmaceuticals, biologics, and electronics.

If certain patents issued to others are upheld or if certain patent applications filed by others issue and are upheld, we may require certain licenses from others in order to develop and commercialize certain potential products incorporating our technology.  There can be no assurance that such licenses, if required, will be available on acceptable terms.

Where appropriate, we also rely on trade secrets to protect aspects of our technology.  However, trade secrets are difficult to protect.  We protect our proprietary technology and processes, in part, by confidentiality agreements with our employees, consultants and collaborators.  These parties may breach these agreements, and we may not have adequate remedies for any breach.  Our trade secrets may otherwise become known or be independently discovered by competitors.  To the extent that we or our consultants or collaborators use intellectual property owned by others, we may have disputes with our collaborators or consultants or other third parties as to the rights in related or resulting know-how and inventions.

International Operations; Financial Information About Geographic Areas

We believe, because the pharmaceutical industry is global in nature, international activities will be a significant part of our future business activities and, when and if we are able to generate income, a substantial portion of that income may be derived from product sales and other activities outside the United States.  As one of our immediate strategic goals is to establish XOMA as a commercial organization in the United States, we will rely upon other companies to market our product outside of the United States for the foreseeable future.  Our decision to retain the U.S. commercial rights to our product candidates while licensing the rights to our product candidates outside the United States, or to license our product candidates globally to one or more partners, depends upon a number of factors, including the primary indication and size of the potential patient population, the size of the clinical trials required to obtain marketing approval in the United States and globally, and the size of the sales force required to sell the product.

A number of risks are inherent in international operations.  Foreign regulatory agencies often establish standards different from those in the United States. An inability to obtain foreign regulatory approvals on a timely basis could have an adverse effect on our international business, financial condition and results of operations.  International operations may be limited or disrupted by the imposition of government controls, export license requirements, political or economic instability, trade restrictions, changes in tariffs, restrictions on repatriating profits, taxation or difficulties in staffing and managing international operations.  In addition, our business, financial condition and results of operations may be adversely affected by fluctuations in currency exchange rates.  There can be no assurance that we will be able to successfully operate in any foreign market.

Financial information regarding the geographic areas in which we operate and segment information is included in Note 12 to the December 31, 2013, Financial Statements: Concentration of Risk, Segment and Geographic Information .

Concentration of Risk

In 2013, Servier, NIAID and Novartis accounted for 43 percent, 26 percent and 20 percent, respectively, of our total revenue. Servier and NIAID accounted for 47 percent and 33 percent, respectively, of our total revenue in 2012 and 61 percent and 32 percent, respectively, in 2011. At December 31, 2013, Servier and NIAID accounted for 13 percent and 73 percent of the accounts receivable balance, compared to 58 percent and 35 percent, respectively, at the same period in 2012, and 57 percent and 43 percent, respectively, at the same period of 2011.  None of these parties represent a related party to XOMA and the loss of one or more of these customers could have a material effect on our business and financial condition.

Organization

We were incorporated in Delaware in 1981 and became a Bermuda-exempted company in December 1998.  Effective December 31, 2011, we changed our jurisdiction of incorporation from Bermuda to Delaware and changed our name from XOMA Ltd. to XOMA Corporation.  When referring to a time or period before December 31, 1998, or when the context so requires, the terms “Company” and “XOMA” refer to XOMA Corporation, a Delaware corporation, and when referring to a time or period after December 31, 1998, and before December 31, 2011, such terms refer to XOMA Ltd., a Bermuda company.

Item 1A.

Risk Factors

The following risk factors and other information included in this annual report should be carefully considered. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us also may impair our business operations. If any of the following risks occur, our business, financial condition, operating results and cash flows could be materially adversely affected.

Because our product candidates are still being developed, we will require substantial funds to continue; we cannot be certain that funds will be available, and if they are not available, we may have to take actions that could adversely affect your investment and may not be able to continue operations.

We will need to commit substantial funds to continue development of our product candidates, and we may not be able to obtain sufficient funds on acceptable terms, or at all. If we raise additional funds by issuing equity securities, our stockholders will experience dilution. Any debt financing or additional equity that we raise may contain terms that are not favorable to our stockholders or us. If we raise additional funds through collaboration and licensing arrangements with third parties, we may be required to relinquish some rights to our technologies or our product candidates, grant licenses on terms that are not favorable to us or enter into a collaboration arrangement for a product candidate at an earlier stage of development or for a lesser amount than we might otherwise choose.

Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available on a timely basis, we may:

Table of Contents

 

·

terminate or delay clinical trials for one or more of our product candidates;

·

further reduce our headcount and capital or operating expenditures; or

·

curtail our spending on protecting our intellectual property.

We finance our operations primarily through our multiple revenue streams resulting from discovery and development collaborations, biodefense contracts, the licensing of our antibody technologies, and through sales of our common stock.

Based on our cash, cash equivalents and short-term investments of $121.6 million at December 31, 2013, anticipated spending levels, anticipated cash inflows from collaborations, biodefense contracts and licensing transactions, funding availability included under our loan agreements, the proceeds from our equity offerings and other sources of funding that we believe to be available, we believe we have sufficient cash resources to meet our anticipated net cash needs into 2015. Any significant revenue shortfalls, increases in planned spending on development programs, more rapid progress of development programs than anticipated, or the initiation of new clinical trials, as well as the unavailability of anticipated sources of funding, could shorten this period or otherwise have a material adverse impact on our ability to finance our continued operations. Progress or setbacks by potentially competing products also may affect our ability to raise new funding on acceptable terms. We do not know when or whether:

 

·

operations will generate meaningful funds;

·

additional agreements for product development funding can be reached;

·

strategic alliances can be negotiated; or

·

adequate additional financing will be available for us to finance our own development on acceptable terms, or at all.

 

If adequate funds are not available, we will be required to delay, reduce the scope of, or eliminate one or more of our product development programs and further reduce personnel-related costs.

We have sustained losses in the past, and we expect to sustain losses in the future.

 

We have been and are developing numerous product candidates, and as a result have experienced significant losses. As of December 31, 2013, we had an accumulated deficit of $1,081.2 million.

For the year ended December 31, 2013, we had a net loss of approximately $124.1 million, or $1.43 per share of common stock (basic and diluted). For the year ended December 31, 2012, we had a net loss of approximately $71.1 million, or $1.10 per share of common stock (basic and diluted).

Our ability to achieve profitability is dependent in large part on the success of our development programs, obtaining regulatory approval for our product candidates and licensing certain of our preclinical compounds, all of which are uncertain. Our product candidates are still being developed, and we do not know whether we will ever achieve sustained profitability or whether cash flow from future operations will be sufficient to meet our needs.

 

We are substantially dependent on Servier for the development and commercialization of gevokizumab and for other aspects of our business, and if we are unable to maintain our relationship with Servier, or Servier does not perform under its agreements with us, our business would be harmed significantly.

We have a number of agreements with Servier that are material to the conduct of our business, including:

·

In December 2010, we entered into a license and collaboration agreement with Servier, to jointly develop and commercialize gevokizumab in multiple indications. Under the terms of the agreement, Servier has worldwide rights to cardiovascular disease and diabetes indications and rights outside the United States and Japan to all other indications, including Behçet’s uveitis and other inflammatory and oncology indications. In late 2011, we announced Servier agreed to include the NIU Phase 3 trials under the terms of the collaboration agreement for Behçet’s uveitis. We retain development and commercialization rights for NIU and other inflammatory disease and oncology indications in the United States and Japan and have an option to reacquire rights to cardiovascular disease and diabetes indications from Servier in these territories. Should we exercise this option, we will be required to pay an option fee to Servier and partially reimburse a specified portion of Servier’s incurred development expenses. The agreement contains mutual customary termination rights relating to matters such as material breach by either party. Servier may terminate for safety issues, and we may terminate the agreement, with respect to a particular country or the European Patent Organization (“EPO”) member states, for any challenge to our patent rights in that country or any EPO member state, respectively, by Servier. Servier also has a unilateral right to terminate the agreement for the European Union (“EU”) or for non-EU countries, on a country-by-country basis, or in its entirety, in each case with six months’ notice.

In December 2010, we entered into a loan agreement with Servier (the “Servier Loan Agreement”), which provides for an advance of up to €15.0 million and was funded fully in January 2011 with the proceeds converting to approximately $19.5 million at the January 13, 2011, Euro-to-U.S.-dollar exchange rate of 1.3020. This loan is secured by an interest in our intellectual property rights to all gevokizumab indications worldwide, excluding the United States and Japan. The loan has a final maturity date in 2016; however, after a specified period prior to final maturity, the loan is required to be repaid (1) at Servier’s option, by applying up to a significant percentage of any milestone or royalty payments owed by Servier under our collaboration agreement and (2) using a significant percentage of any upfront, milestone or royalty payments we receive from any third-party collaboration or development partner for rights to gevokizumab in the United States and/or Japan. In addition, the loan becomes immediately due and payable upon certain customary events of default. At December 31, 2013, the €15.0 million outstanding principal balance under this Servier Loan Agreement would have equaled approximately $20.6 million using the December 31, 2013 Euro-to-U.S.-dollar exchange rate of 1.3766.

Because Servier is an independent third party, it may be subject to different risks than we are and has significant discretion in, and different criteria for, determining the efforts and resources it will apply related to its agreements with us. Even though we have a collaborative relationship with Servier, our relationship could deteriorate or other circumstances may prevent our relationship with Servier from resulting in successful development of marketable products. If we are not able to maintain our working relationship with Servier, or if Servier does not perform under its agreements with us, our ability to develop and commercialize gevokizumab would be materially and adversely affected.

If our therapeutic product candidates do not receive regulatory approval, neither our third-party collaborators nor we will be able to market them.

Our product candidates (including gevokizumab, XMetA, XMetD, XMetS, and XOMA 3AB) cannot be manufactured and marketed in the United States or any other countries without required regulatory approvals. The U.S. government and governments of other countries extensively regulate many aspects of our product candidates, including:

 

·

clinical development and testing;

·

manufacturing;

·

labeling;

·

storage;

·

record keeping;

·

promotion and marketing; and

·

importing and exporting.

In the United States, the FDA regulates pharmaceutical products under the Federal Food, Drug, and Cosmetic Act and other laws, including, in the case of biologics, the Public Health Service Act. At the present time, we believe many of our product candidates (including gevokizumab, XMetA, XMetD, XMetS and XOMA 3AB) will be regulated by the FDA as biologics and some of our product candidates will be regulated by the FDA as drugs. Initiation of clinical trials requires approval by health authorities. Clinical trials involve the administration of the investigational new drug to healthy volunteers or to patients under the supervision of a qualified principal investigator. Clinical trials must be conducted in accordance with FDA and International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use Good Clinical Practices and the European Clinical Trials Directive under protocols that detail the objectives of the study, the parameters to be used to monitor safety and the efficacy criteria to be evaluated. Other national, foreign and local regulations also may apply. The developer of the drug must provide information relating to the characterization and controls of the product before administration to the patients participating in the clinical trials. This requires developing approved assays of the product to test before administration to the patient and during the conduct of the trial. In addition, developers of pharmaceutical products must provide periodic data regarding clinical trials to the FDA and other health authorities, and these health authorities may issue a clinical hold upon a trial if they do not believe, or cannot confirm, that the trial can be conducted without unreasonable risk to the trial participants. We cannot assure you that U.S. and foreign health authorities will not issue a clinical hold with respect to any of our clinical trials in the future.

Table of Contents

The results of the preclinical studies and clinical testing, together with chemistry, manufacturing and controls information, are submitted to the FDA and other health authorities in the form of an NDA for a drug, and in the form of a Biologic License Application (“BLA”) for a biological product, requesting approval to commence commercial sales. In responding to an NDA or BLA, the FDA or foreign health authorities may grant marketing approvals, request additional information or further research, or deny the application if it determines the application does not satisfy its regulatory approval criteria. Regulatory approval of an NDA, BLA, or supplement never is guaranteed, the approval process can take several years, is extremely expensive and can vary substantially based upon the type, complexity, and novelty of the products involved, as well as the target indications. FDA regulations and policies permit applicants to request accelerated or priority review pathways for products intended to treat certain serious or life-threatening illnesses in certain circumstances. If granted by the FDA, these review pathways can provide a shortened timeline to commercialize the product, although the shortened review timeline is often accompanied with additional post-market requirements. Although we may pursue the FDA’s accelerated or priority review programs, we cannot guarantee the FDA will permit us to utilize these pathways or the FDA’s review of our application will not be delayed. Moreover, even if the FDA agrees to an accelerated or priority review of any of our applications, we may not ultimately be able to obtain approval of our application in a timely fashion or at all. The FDA and foreign health authorities have substantial discretion in the drug and biologics approval processes. Despite the time and expense incurred, failure can occur at any stage, and we could encounter problems that cause us to abandon clinical trials or to repeat or perform additional preclinical, clinical or manufacturing-related studies.

 

Changes in the regulatory approval policy during the development period, changes in, or the enactment of additional regulations or statutes, or changes in regulatory review for each submitted product application may cause delays in the approval or rejection of an application. State regulations may also affect our proposed products.

The FDA and other regulatory agencies have substantial discretion in both the product approval process and manufacturing facility approval process, and as a result of this discretion and uncertainties about outcomes of testing, we cannot predict at what point, or whether, the FDA or other regulatory agencies will be satisfied with our or our collaborators’ submissions or whether the FDA or other regulatory agencies will raise questions that may be material and delay or preclude product approval or manufacturing facility approval. In light of this discretion and the complexities of the scientific, medical and regulatory environment, our interpretation or understanding of the FDA’s or other regulatory agencies’ requirements, guidelines or expectations may prove incorrect, which also could delay further or increase the cost of the approval process. As we accumulate additional clinical data, we will submit it to the FDA and other regulatory agencies, as appropriate, and such data may have a material impact on the approval process.

Given that regulatory review is an interactive and continuous process, we maintain a policy of limiting announcements and comments upon the specific details of regulatory review of our product candidates, subject to our obligations under the securities laws, until definitive action is taken.

We have received negative results from certain of our clinical trials, and we face uncertain results of other clinical trials of our product candidates.

 

Drug development has inherent risk, and we are required to demonstrate through adequate and well-controlled clinical trials that our product candidates are effective, with a favorable benefit-risk profile for use in their target profiles before we can seek regulatory approvals for their commercial use. It is possible we may never receive regulatory approval for any of our product candidates. Even if a product candidate receives regulatory approval, the resulting product may not gain market acceptance among physicians, patients, healthcare payors and the medical community. In March 2011, we announced our 421-patient Phase 2b trial of gevokizumab in Type 2 diabetes did not achieve the primary endpoint of reduction in hemoglobin A1c (“HbA1c”) after six monthly treatments with gevokizumab compared to placebo. In June 2011, we announced top-line trial results from our six-month 74-patient Phase 2a trial of gevokizumab in Type 2 diabetes, and there were no differences in glycemic control between the drug and placebo groups as measured by HbA1c levels.

Many of our product candidates, including gevokizumab, XMet and XOMA 3AB, require significant additional research and development, extensive preclinical studies and clinical trials and regulatory approval prior to any commercial sales. This process is lengthy and expensive, often taking a number of years. As clinical results frequently are susceptible to varying interpretations that may delay, limit or prevent regulatory approvals, the length of time necessary to complete clinical trials and to submit an application for marketing approval for a final decision by a regulatory authority varies significantly. As a result, it is uncertain whether:

 

·

our future filings will be delayed;

·

our preclinical and clinical studies will be successful;

·

we will be successful in generating viable product candidates to targets;

·

we will be able to provide necessary additional data;

·

results of future clinical trials will justify further development; or

·

we ultimately will achieve regulatory approval for any of these product candidates.

The timing of the commencement, continuation and completion of clinical trials may be subject to significant delays relating to various causes, including completion of preclinical testing and earlier-stage clinical trials in a timely manner, engaging contract research organizations and other service providers, scheduling conflicts with participating clinicians and clinical institutions, difficulties in identifying and enrolling patients who meet trial eligibility criteria and shortages of available drug supply. Patient enrollment is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the existence of competing clinical trials and the availability of alternative or new treatments. Regardless of the initial size or relative complexity of a clinical trial, the costs of such trial may be higher than expected due to increases in duration or size of the trial, changes in the protocol pursuant to which the trial is being conducted, additional or special requirements of one or more of the healthcare centers where the trial is being conducted, or changes in the regulatory requirements applicable to the trial or in the standards or guidelines for approval of the product candidate being tested or for other unforeseen reasons. In addition, we conduct clinical trials in foreign countries, which may subject us to further delays and expenses as a result of increased drug shipment costs, additional regulatory requirements and the engagement of foreign clinical research organizations, as well as expose us to risks associated with foreign currency transactions insofar as we might desire to use U.S. Dollars to make contract payments denominated in the foreign currency where the trial is being conducted.

All of our product candidates are prone to the risks of failure inherent in drug development. Preclinical studies may not yield results that satisfactorily support the filing of an Investigational New Drug application (“IND”) (or a foreign equivalent) with respect to our product candidates. Even if these applications would be or have been filed with respect to our product candidates, the results of preclinical studies do not necessarily predict the results of clinical trials. Similarly, early stage clinical trials in healthy volunteers do not predict the results of later-stage clinical trials, including the safety and efficacy profiles of any particular product candidates. In addition, there can be no assurance the design of our clinical trials is focused on appropriate indications, patient populations, dosing regimens or other variables that will result in obtaining the desired efficacy data to support regulatory approval to commercialize the drug. Moreover, FDA officials or foreign regulatory agency officials may question the integrity of our data or otherwise subject our clinical trials to additional scrutiny when the clinical trials are conducted by principal investigators who serve, or previously served, as scientific advisors or consultants to us and receive cash compensation in connection with such services. Preclinical and clinical data can also be interpreted in different ways. Accordingly, FDA officials or officials from foreign regulatory authorities could interpret the data differently than we or our collaboration or development partners do, which could delay, limit or prevent regulatory approval.

Administering any of our products or potential products may produce undesirable side effects, also known as adverse effects. Toxicities and adverse effects that we have observed in preclinical studies for some compounds in a particular research and development program may occur in preclinical studies or clinical trials of other compounds from the same program. Such toxicities or adverse effects could delay or prevent the filing of an IND (or a foreign equivalent) with respect to such products or potential products or cause us to cease clinical trials with respect to any drug candidate. In clinical trials, administering any of our products or product candidates to humans may produce adverse effects. These adverse effects could interrupt, delay or halt clinical trials of our products and product candidates and could result in the FDA or other regulatory authorities denying approval of our products or product candidates for any or all targeted indications. The FDA, other regulatory authorities, our collaboration or development partners or we may suspend or terminate clinical trials at any time. Even if one or more of our product candidates were approved for sale, the occurrence of even a limited number of toxicities or adverse effects when used in large populations may cause the FDA to impose restrictions on, or stop, the further marketing of such drugs. Indications of potential adverse effects or toxicities that may occur in clinical trials and that we believe are not significant during the course of such clinical trials may actually turn out later to constitute serious adverse effects or toxicities when a drug has been used in large populations or for extended periods of time. Any failure or significant delay in completing preclinical studies or clinical trials for our product candidates, or in receiving and maintaining regulatory approval for the sale of any drugs resulting from our product candidates, may severely harm our reputation and business.

We rely on third parties to provide services in connection with our product candidate development and manufacturing programs. The inadequate performance by or loss of any of these service providers could affect our product candidate development.

Several third parties provide services in connection with our preclinical and clinical development programs, including in vitro and in vivo studies, assay and reagent development, immunohistochemistry, toxicology, pharmacokinetics, clinical trial support, manufacturing and other outsourced activities. If these service providers do not adequately perform the services for which we have contracted or cease to continue operations and we are not able to find a replacement provider quickly or we lose information or items associated with our product candidates, our development programs may be delayed.

We may not obtain orphan drug exclusivity, or we may not receive the full benefit of orphan drug exclusivity even if we obtain such exclusivity.

The FDA has awarded orphan drug status to gevokizumab for the treatment of non-infectious, intermediate, posterior or pan uveitis, and chronic non-infectious anterior uveitis and Behçet’s uveitis. Under the Orphan Drug Act, the first company to receive FDA approval for gevokizumab for the designated orphan drug indication will obtain seven years of marketing exclusivity, during which time the FDA may not approve another company’s application for gevokizumab for the same orphan indication. Even though we have obtained orphan drug designation for certain indications for gevokizumab and even if we obtain orphan drug designation for our future product candidates or other indications, due to the uncertainties associated with developing pharmaceutical products, we may not be the first to obtain marketing approval for any particular orphan indication, or we may not obtain approval for an indication for which we have obtained orphan drug designation. Further, even if we obtain orphan drug exclusivity for a product, that exclusivity may not protect the product effectively from competition because different drugs can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition if the FDA concludes that the later drug is safer, more effective or makes a major contribution to patient care. Orphan drug designation neither shortens the development time or regulatory review time of a drug, nor gives the drug any advantage in the regulatory review or approval process.

Even after FDA approval, a product may be subject to additional testing or significant marketing restrictions, its approval may be withdrawn or it may be removed voluntarily from the market.

 

Even if we receive regulatory approval for our product candidates, we will be subject to ongoing regulatory oversight and review by the FDA and other regulatory entities. The FDA, the European Commission or another regulatory agency may impose, as a condition of the approval, ongoing requirements for post-approval studies or post-approval obligations, including additional research and development and clinical trials, and the FDA, European Commission or other regulatory agency subsequently may withdraw approval based on these additional trials. For example, we initiated commercial operations in January 2012 through the licensing of U.S. commercial rights to Servier’s ACEON® (perindopril erbumine) and certain U.S. rights to a patent-protected portfolio of fixed dose combination (“FDC”) product candidates where perindopril is combined with other active ingredients to treat cardiovascular disease. Although we transferred the U.S. development and commercialization rights to the perindopril franchise to Symplmed Pharmaceuticals, LLC (“Symplmed”), we continue to hold the ACEON® NDA until transferred. As the holder of the ACEON NDA, we are subject to post-approval obligations for ACEON, including that we are required to submit annual reports to the FDA and are responsible for pharmacovigilance activities related to the product.

Even for approved products, the FDA, European Commission or other regulatory agency may impose significant restrictions on the indicated uses, conditions for use, labeling, advertising, promotion, marketing and/or production of such product. In addition, the labeling, packaging, adverse event reporting, storage, advertising, promotion and record-keeping for our products are subject to extensive regulatory requirements.

 

Furthermore, a marketing approval of a product may be withdrawn by the FDA, the European Commission or another regulatory agency or such a product may be withdrawn voluntarily by the company marketing it based, for example, on subsequently arising safety concerns. In February 2009, the European Medicines Agency (“EMA”) announced it had recommended suspension of the marketing authorization of RAPTIVA ® in the EU and its Committee for Medicinal Products for Human Use (“CHMP”) had concluded the benefits of RAPTIVA no longer outweigh its risks because of safety concerns, including the occurrence of progressive multifocal leukoencephalopathy (“PML”) in patients taking the medicine. In the second quarter of 2009, Genentech announced and carried out a phased voluntary withdrawal of RAPTIVA from the U.S. market, based on the association of RAPTIVA with an increased risk of PML. We had participated in the development of RAPTIVA.

 

The FDA, European Commission and other agencies also may impose various civil or criminal sanctions for failure to comply with regulatory requirements, including withdrawal of product approval.

We may issue additional equity securities and thereby materially and adversely affect the price of our common stock.

 

We are authorized to issue, without stockholder approval, 1,000,000 shares of preferred stock, of which none were issued and outstanding as of March 10, 2014, which may give other stockholders dividend, conversion, voting, and liquidation rights, among other rights, which may be superior to the rights of holders of our common stock. In addition, we are authorized to issue, generally without stockholder approval, up to 138,666,666 shares of common stock, of which 106,571,513 were issued and outstanding as of March 10, 2014. If we issue additional equity securities, the price of our common stock may be materially and adversely affected.

On February 4, 2011, we entered into an At Market Issuance Sales Agreement (the “2011 ATM Agreement”) with McNicoll, Lewis & Vlak LLC (now known as MLV & Co. LLC, “MLV”), under which we may sell shares of our common stock from time to time through the MLV, as our agent for the offer and sale of the shares, in an aggregate amount not to exceed the amount that can be sold under our Registration Statement on Form S-3 (File No. 333-172197) filed with the SEC on February 11, 2011, and amended on March 10, 2011, June 3, 2011, and January 3, 2012, which was most recently declared effective by the SEC on January 17, 2012. MLV may sell the shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act, including without limitation sales made directly on The NASDAQ Global Market, on any other existing trading market for our common stock or to or through a market maker. MLV also may sell the shares in privately negotiated transactions, subject to our prior approval. From the inception of the 2011 ATM Agreement through March 10, 2014, we sold a total of 7,572,327 shares of common stock under this agreement for aggregate gross proceeds of $14.6 million. The registration statement under which the 2011 ATM was entered expires in June of 2014.

As part of our fundraising efforts, from time to time we offer securities through underwritten public offerings.  In 2013, we completed two such offerings, one in August 2013 where we sold 8,736,187 shares of our common stock at a public offering price of $3.62 per share and the other in December 1 2013, where we sold  10,925,000 shares of our common stock   at a public offering price of $5.25 per share.

In addition, funding from collaboration partners and others has in the past and may in the future involve issuance by us of our shares of common stock. We cannot be certain how the purchase price of such shares, the relevant market price or premium, if any, will be determined or when such determinations will be made.

Any issuance by us of equity securities, whether through an underwritten public offering, an at the market offering, a private placement, in connection with a collaboration or otherwise could result in dilution in the value of our issued and outstanding shares, and a decrease in the trading price of our common stock.

 

Our share price may be volatile and there may not be an active trading market for our common stock.

 

There can be no assurance the market price of our common stock will not decline below its present market price or there will be an active trading market for our common stock. The market prices of biotechnology companies have been and are likely to continue to be highly volatile. Fluctuations in our operating results and general market conditions for biotechnology stocks could have a significant impact on the volatility of our common stock price. We have experienced significant volatility in the price of our common stock. From January 1, 2013, through March 10, 2014, the share price of our common stock has ranged from a high of $9.57 to a low of $2.43. Factors contributing to such volatility include, but are not limited to:

 

·

results of preclinical studies and clinical trials;

·

information relating to the safety or efficacy of products or product candidates;

·

developments regarding regulatory filings;

·

announcements of new collaborations;

·

failure to enter into collaborations;

·

developments in existing collaborations;

·

our funding requirements and the terms of our financing arrangements;

·

technological innovations or new indications for our therapeutic products and product candidates;

·

introduction of new products or technologies by us or our competitors;

·

sales and estimated or forecasted sales of products for which we receive royalties, if any;

·

government regulations;

·

developments in patent or other proprietary rights;

·

the number of shares issued and outstanding;

·

the number of shares trading on an average trading day;

·

announcements regarding other participants in the biotechnology and pharmaceutical industries; and

·

market speculation regarding any of the foregoing.

We may not be successful in commercializing our products, which could affect our development efforts.

We began commercializing our first product, ACEON, in January 2012, and we have limited experience in the sales, marketing and distribution of pharmaceutical products. We transferred U.S. development and commercialization rights to ACEON and the perindopril franchise to Symplmed in July 2013. Although Symplmed, under a sublicense agreement, assumes U.S. marketing responsibilities for ACEON (perindopril erbumine), XOMA continues to manage and be reimbursed for sales and distribution within its established commercial infrastructure until the ACEON NDA is transferred to Symplmed. There can be no assurance we will be able to successfully manage the transfer or commercialization activities to Symplmed or maintain the arrangements we have with third-party suppliers, distributors and other service providers that are necessary for us to perform these activities or our efforts will be successful. Transferring, maintaining or expanding these arrangements, or developing our own capabilities, may divert attention and resources from or otherwise negatively affect our development programs.

We are subject to various state and federal healthcare related laws and regulations that may impact the commercialization of our product candidates or could subject us to significant fines and penalties.

Our operations may be directly or indirectly subject to various state and federal healthcare laws, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act and state and federal privacy and security laws. These laws may impact, among other things, the commercial operations for ACEON and any of our product candidates that may be approved for commercial sale.

The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing or arranging for a good or service, for which payment may be made under a federal healthcare program, such as the Medicare and Medicaid programs. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. The Anti-Kickback Statute is broad and prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. Penalties for violations of the federal Anti-Kickback Statute include criminal penalties and civil sanctions such as fines, penalties, imprisonment and possible exclusion from Medicare, Medicaid and other federal healthcare programs.

The federal False Claims Act prohibits persons from knowingly filing, or causing to be filed, a false claim to, or the knowing use of false statements to obtain payment from the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of the government and such individuals, commonly known as “whistleblowers”, may share in any amounts paid by the entity to the government in fines or settlement. The filing of qui tam actions has caused a number of pharmaceutical, medical device and other healthcare companies to have to defend a False Claims Act action. When an entity is determined to have violated the False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim. Various states also have enacted laws modeled after the federal False Claims Act.

The Federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), created new federal criminal statutes that prohibit executing a scheme to defraud any healthcare benefit program and making false statements relating to healthcare matters. The health care fraud statute prohibits knowingly and willfully executing a scheme to defraud any health care benefit program, including private payors. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for health care benefits, items or services. HIPAA, as amended by the Health Information Technology and Clinical Health Act (“HITECH”), and its implementing regulations, also impose certain requirements relating to the privacy, security and transmission of individually identifiable health information. We take our obligation to maintain our compliance with these various laws and regulations seriously.

In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians. The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively, PPACA, among other things, imposed new requirements on manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to the Centers for Medicare & Medicaid Services, or CMS, information related to payments or other “transfers of value” made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, and applicable manufacturers and group purchasing organizations to report annually to CMS ownership and investment interests held by physicians (as defined above) and their immediate family members and payments or other “transfers of value” to such physician owners and their immediate family members. Manufacturers were required to begin data collection on August 1, 2013 and will be required to report such data to the government by March 31, 2014 and by the 90 th calendar day of each year thereafter. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 per year (or up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests not reported in an annual submission.

Many states also have adopted laws similar to each of the federal laws described above, some of which apply to healthcare items or services reimbursed by any source, not only the Medicare and Medicaid programs. In addition, some states have laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government, or otherwise restrict payments that may be made to healthcare providers and other potential referral sources, and to report information related to payments and other transfers of value to physicians and other healthcare providers; and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

Because of the breadth of these laws, it is possible that some of our business activities could be subject to challenge under one or more of such laws. The PPACA also make several important changes to the federal Anti-Kickback Statute, false claims laws, and health care fraud statute by weakening the intent requirement under the anti-kickback and health care fraud statutes that may make it easier for the government, or whistleblowers to charge such fraud and abuse violations. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the PPACA provides that the government may assert that a claim including items or services resulting from a violation of the federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the false claims statutes.

If we are found to be in violation of any of the laws and regulations described above or other applicable state and federal healthcare laws, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from government healthcare reimbursement programs and the curtailment or restructuring of our operations, any of which could have a material adverse effect on our business and results of operations.

Certain of our technologies are in-licensed from third parties, so our capabilities using them are restricted and subject to additional risks.

 

We license technologies from third parties. These technologies include but are not limited to phage display technologies licensed to us in connection with our bacterial cell expression technology licensing program and antibody products. However, our use of these technologies is limited by certain contractual provisions in the licenses relating to them, and although we have obtained numerous licenses, intellectual property rights in the area of phage display are particularly complex. If the owners of the patent rights underlying the technologies that we license do not properly maintain or enforce those patents, our competitive position and business prospects could be harmed. Our success will depend in part on the ability of our licensors to obtain, maintain and enforce our in-licensed intellectual property. Our licensors may not be successful in prosecuting the patent applications to which we have licenses, or our licensors may fail to maintain existing patents. They may determine not to pursue litigation against other companies that are infringing these patents, or they may pursue such litigation less aggressively than we would. Our licensors also may seek to terminate our license, which could cause us to lose the right to use the licensed intellectual property and adversely affect our ability to commercialize our technologies, products or services.

We do not know whether there will be, or will continue to be, a viable market for the products in which we have an ownership or royalty interest.

 

Even if products in which we have an interest receive approval in the future, they may not be accepted in the marketplace. In addition, we or our collaborators or licensees may experience difficulties in launching new products, many of which are novel and based on technologies that are unfamiliar to the healthcare community. We have no assurance healthcare providers and patients will accept such products, if developed. For example, physicians and/or patients may not accept a product for a particular indication because it has been biologically derived (and not discovered and developed by more traditional means) or if no biologically derived products are currently in widespread use in that indication. Similarly, physicians may not accept a product if they believe other products to be more effective or more cost effective or are more comfortable prescribing other products.

Safety concerns also may arise in the course of on-going clinical trials or patient treatment as a result of adverse events or reactions. For example, in February 2009, the EMA announced it had recommended suspension of the marketing authorization of RAPTIVA in the EU and EMD Serono Inc., the company that marketed RAPTIVA in Canada (“EMD Serono”) announced that in consultation with Health Canada, the Canadian health authority (“Health Canada”), it would suspend marketing of RAPTIVA in Canada. In March 2009, Merck Serono Australia Pty Ltd, the company that marketed RAPTIVA in Australia (“Merck Serono Australia”), following a recommendation from the Therapeutic Goods Administration, the Australian health authority (“TGA”), announced it was withdrawing RAPTIVA from the Australian market. In the second quarter of 2009, Genentech announced and carried out a phased voluntary withdrawal of RAPTIVA from the U.S. market, based on the association of RAPTIVA with an increased risk of PML, and sales of the product ceased.

Furthermore, government agencies, as well as private organizations involved in healthcare, from time to time publish guidelines or recommendations to healthcare providers and patients. Such guidelines or recommendations can be very influential and may adversely affect product usage directly (for example, by recommending a decreased dosage of a product in conjunction with a concomitant therapy or a government entity withdrawing its recommendation to screen blood donations for certain viruses) or indirectly (for example, by recommending a competitive product over our product). Consequently, we do not know if physicians or patients will adopt or use our products for their approved indications.

Even approved and marketed products are subject to risks relating to changes in the market for such products. Introduction or increased availability of generic versions of products can alter the market acceptance of branded products, such as ACEON. In addition, unforeseen safety issues may arise at any time, regardless of the length of time a product has been on the market.

In addition to our agreements with Servier, our agreements with other third parties, many of which are significant to our business, expose us to numerous risks.

 

Our financial resources and our marketing experience and expertise are limited. Consequently, our ability to develop products successfully depends, to a large extent, upon securing the financial resources and/or marketing capabilities of third parties other than Servier. For example:

 

·

In March 2004, we announced we had agreed to collaborate with Chiron Corporation (now Novartis) for the development and commercialization of antibody products for the treatment of cancer. In April 2005, we announced the initiation of clinical testing of the first product candidate out of the collaboration, HCD122, an anti-CD40 antibody, in patients with advanced chronic lymphocytic leukemia. In October 2005, we announced the initiation of the second clinical trial of HCD122 in patients with multiple myeloma. In November 2008, we announced the restructuring of this product development collaboration, which involved six development programs including the ongoing HCD122 and LFA102 programs. In exchange for cash and debt reduction on our existing loan facility with Novartis, Novartis has control over the HCD122 and LFA102 programs, as well as the right to expand the development of these programs into additional indications outside of oncology.

 

·

In March 2005, we entered into a contract with the National Institute of Allergy and Infectious Diseases (“NIAID”) to produce three monoclonal antibodies designed to protect U.S. citizens against the harmful effects of botulinum neurotoxin used in bioterrorism. In July 2006, we entered into an additional contract with NIAID for the development of an appropriate formulation for human administration of these three antibodies in a single injection. In September 2008, we announced we had been awarded an additional contract with NIAID to support our on-going development of drug candidates toward clinical trials in the treatment of botulism poisoning. In October 2011, we announced we had been awarded an additional contract with NIAID to develop broad-spectrum antitoxins for the treatment of human botulism poisoning.

 

·

We have licensed our bacterial cell expression technology, an enabling technology used to discover and screen, as well as develop and manufacture, recombinant antibodies and other proteins for commercial purposes, to over 60 companies. As of March 10, 2014, we were aware of two antibody products manufactured using this technology that have received FDA approval, Genentech’s LUCENTIS ® (ranibizumab injection) for treatment of neovascular wet age-related macular degeneration and UCB’s CIMZIA ® (certolizumab pegol) for treatment of Crohn’s disease and rheumatoid arthritis. In the third quarter of 2009, we sold our LUCENTIS royalty interest to Genentech. In the third quarter of 2010, we sold our CIMZIA royalty interest.

 

·

On July 24, 2012, Servier and we entered into an agreement with Boehringer Ingelheim to transfer XOMA's technology and processes for the manufacture of gevokizumab to Boehringer lngelheim for Boehringer Ingelheim's implementation and validation in preparation for the commercial manufacture of gevokizumab. Upon the successful completion of the transfer and the establishment of biological comparability, including validation of the XOMA processes as implemented by Boehringer Ingelheim, we intend Boehringer Ingelheim will produce gevokizumab for XOMA's commercial use at its facility in Biberach, Germany. Servier and we retain all rights to the development and commercialization of gevokizumab. Transferring of our technology to Boehringer Ingelheim exposes us to numerous risks, including the possibility that Boehringer Ingelheim may not perform under the agreement as anticipated, and that we will need to successfully conduct a comparability trial demonstrating to the FDA’s satisfaction the similarity between XOMA-manufactured and Boehringer Ingelheim-manufactured product.

Because our collaborators, licensees, suppliers and contractors are independent third parties, they may be subject to different risks than we are and have significant discretion in, and different criteria for, determining the efforts and resources they will apply related to their agreements with us. If these collaborators, licensees, suppliers and contractors do not successfully perform the functions for which they are responsible, we may not have the capabilities, resources or rights to do so on our own.

We do not know whether we, our collaborators or licensees will successfully develop and market any of the products that are or may become the subject of any of our collaboration or licensing arrangements. In some cases these arrangements provide for funding solely by our collaborators or licensees, and in other cases, all of the funding for certain projects and a significant portion of the funding for other projects is to be provided by our collaborator or licensee, and we provide the balance of the funding. Even when we have a collaborative relationship, other circumstances may prevent it from resulting in successful development of marketable products. In addition, third-party arrangements such as ours also increase uncertainties in the related decision-making processes and resulting progress under the arrangements, as we and our collaborators or licensees may reach different conclusions, or support different paths forward, based on the same information, particularly when large amounts of technical data are involved. Furthermore, our contracts with NIAID contain numerous standard terms and conditions provided for in the applicable Federal acquisition regulations and customary in many government contracts, some of which could allow the U.S. government to exercise certain rights under the technology developed under these contracts. Uncertainty exists as to whether we will be able to comply with these terms and conditions in a timely manner, if at all. In addition, we are uncertain as to the extent of NIAID’s demands and the flexibility that will be granted to us in meeting those demands.

Although we continue to evaluate additional strategic alliances and potential partnerships, we do not know whether or when any such alliances or partnerships will be entered into.

Products and technologies of other companies may render some or all of our products and product candidates noncompetitive or obsolete.

 

Developments by others may render our products, product candidates, or technologies obsolete or uncompetitive. Technologies developed and utilized by the biotechnology and pharmaceutical industries are changing continuously and substantially. Competition in antibody-based technologies is intense and is expected to increase in the future as a number of established biotechnology firms and large chemical and pharmaceutical companies advance in these fields. Many of these competitors may be able to develop products and processes competitive with or superior to our own for many reasons, including that they may have:

·

significantly greater financial resources;

·

larger research and development and marketing staffs;

·

larger production facilities;

·

entered into arrangements with, or acquired, biotechnology companies to enhance their capabilities; or

·

extensive experience in preclinical testing and human clinical trials.

These factors may enable others to develop products and processes competitive with or superior to our own or those of our collaborators. In addition, a significant amount of research in biotechnology is being carried out in universities and other non-profit research organizations. These entities are becoming increasingly interested in the commercial value of their work and may become more aggressive in seeking patent protection and licensing arrangements. Furthermore, many companies and universities tend not to announce or disclose important discoveries or development programs until their patent position is secure or, for other reasons, later; as a result, we may not be able to track development of competitive products, particularly at the early stages. Positive or negative developments in connection with a potentially competing product may have an adverse impact on our ability to raise additional funding on acceptable terms. For example, if another product is perceived to have a competitive advantage, or another product’s failure is perceived to increase the likelihood that our product will fail, then investors may choose not to invest in us on terms we would accept or at all.

The examples below pertain to competitive events in the market that we review quarterly yet are not intended to be representative of all existing competitive events.

Gevokizumab

 

We, in collaboration with Servier, are developing gevokizumab, a potent monoclonal antibody with unique allosteric modulating properties that binds strongly to interleukin-1 beta (IL-1 beta), a pro-inflammatory cytokine.  In binding to IL-1 beta, gevokizumab inhibits the activation of the IL-1 receptor, thereby modulating the cellular signaling events that produce inflammation . Other companies are developing other products based on the same or similar therapeutic targets as gevokizumab, and these products may prove more effective than gevokizumab. We are aware that:

·

Novartis markets and is developing ILARIS® (canakinumab, ACZ885), a fully human monoclonal antibody that selectively binds to and neutralizes IL-1 beta. Since 2009, canakinumab has been approved in over 50 countries for the treatment of children and adults suffering from Cryopyrin-Associated Periodic Syndrome (“CAPS”). Novartis has filed for regulatory approval of canakinumab in the United States and Europe for the treatment of acute attacks in gouty arthritis. On March 1, 2013, Novartis announced that they received EU approval for Ilaris in patients suffering acute gouty arthritis attacks which cannot gain relief from current treatments. It is administered as a single 150 mg subcutaneous injection. In May 2013, Novartis received FDA approval, and in September 2013 Novartis received EU approval, to treat active systemic juvenile idiopathic arthritis. Novartis also is pursuing other diseases in which IL-1 beta may play a prominent role, such as systemic secondary prevention of cardiovascular events.

·

Eli Lilly and Company (“Lilly”) was developing a monoclonal antibody to IL-1 beta in Phase 1 studies for the treatment of cardiovascular disease. In June 2011, Lilly reported results from a Phase 2 study of LY2189102 in 106 patients with Type 2 diabetes, showing a significant (p<0.05), early reduction in C reactive protein (“CRP”), moderate reduction in HbA1c and anti-inflammatory effects. We do not know whether LY2189102 remains in development.

 

·

In 2008, Swedish Orphan Biovitrum obtained from Amgen the global exclusive rights to Kineret ® (anakinra) for rheumatoid arthritis as currently indicated in its label. In November 2009, the agreement regarding Swedish Orphan Biovitrum’s Kineret license was expanded to include certain orphan indications.  Kineret is an IL-1 receptor antagonist (IL-1ra) that has been evaluated in multiple IL-1-mediated diseases, including indications we are considering for gevokizumab. In addition to other on-going studies, a proof-of-concept clinical trial in the United Kingdom investigating Kineret in patients with a certain type of myocardial infarction, or heart attack, has been completed. In August 2010, Biovitrum announced the FDA had granted orphan drug designation to Kineret for the treatment of CAPS, and in January 2013 they obtained FDA approval for NOMID, a severe form of CAPS. Shanghai CP Guojian Pharmaceutical is developing an injectable formulation of recombinant human IL-1Ra, presumed to be a follow-on biologic version of anakinra , for the potential treatment of rheumatoid arthritis. In February 2010, an NDA was filed with the SFDA; in January 2012, supplemental materials were required by the SFDA to conclude the review.

·	AbbVie is developing ABT-981, a dual variable domain immunoglobulin (DVD-Ig) that incorporates anti-IL-1 alpha and anti-IL-1 beta antibodies, for the potential treatment of osteoarthritis. By January 2012, the drug had entered phase I development.

·

Amgen was developing AMG 108, a fully human monoclonal antibody that targets inhibition of the action of IL-1.  In April 2008, Amgen reported results from a Phase 2 study in rheumatoid arthritis. AMG 108 showed statistically significant improvement in the signs and symptoms of rheumatoid arthritis and was well tolerated. In January 2011, MedImmune, the worldwide biologics unit for AstraZeneca PLC, announced Amgen granted it rights to develop AMG 108 worldwide except in Japan.

 

·

In June 2009, Cytos Biotechnology AG announced the initiation of an ascending dose Phase 1/2a study of CYT013-IL1bQb, a therapeutic vaccine targeting IL-1 beta, in Type 2 diabetes. In 2010, this study was extended to include two additional groups of patients. However, in August 2011, the company put development on hold in order to reduce costs.

 

·

The following companies have completed or are conducting or planning Phase 3 clinical trials of the following products for the treatment of noninfectious intermediate, posterior or pan-uveitis: AbbVie - HUMIRA ® (adalimumab); Lux Biosciences, Inc. – LUVENIQ ® (voclosporin); Novartis - Myfortic ® (mycophenalate sodium) and secukinumab, Santen Pharmaceutical Co., Ltd. – Sirolimus ® (rapamycin), and pSivida Corp. – Fluacinolone Acetonide Intravitreal.

XOMA 3AB

 

We also are developing XOMA 3AB, a combination, or cocktail, of antibodies designed to neutralize the most potent of botulinum toxins. Other companies are developing other products targeting botulism poisoning, and these products may prove more effective than XOMA 3AB. We are aware:

 

·	Emergent Biosolutions Inc. has a contract with the U.S. Department of Health & Human Services, expected to be worth $423.0 million, to manufacture and supply an equine heptavalent botulism anti-toxin. In March 2013, the product was approved by the FDA.

Manufacturing risks and inefficiencies may adversely affect our ability to manufacture products for ourselves or others.

 

To the extent we continue to provide manufacturing services for our own benefit or to third parties, we are subject to manufacturing risks. Additionally, unanticipated fluctuations in customer requirements have led and may continue to lead to manufacturing inefficiencies, which if significant could lead to an impairment on our long-lived assets or restructuring activities. We must utilize our manufacturing operations in compliance with regulatory requirements, in sufficient quantities and on a timely basis, while maintaining acceptable product quality and manufacturing costs. Additional resources and changes in our manufacturing processes may be required for each new product, product modification or customer or to meet changing regulatory or third-party requirements, and this work may not be completed successfully or efficiently.

Manufacturing and quality problems may arise in the future to the extent we continue to perform these manufacturing activities for our own benefit or for third parties. Consequently, our development goals or milestones may not be achieved in a timely manner or at a commercially reasonable cost, or at all. In addition, to the extent we continue to make investments to improve our manufacturing operations, our efforts may not yield the improvements that we expect.

Failure of our products to meet current Good Manufacturing Practices standards may subject us to delays in regulatory approval and penalties for noncompliance.

Our contract manufacturers are required to produce ACEON and our clinical product candidates under current Good Manufacturing Practices (“cGMP”) to meet acceptable standards for use in our clinical trials and for commercial sale, as applicable. If such standards change, the ability of contract manufacturers to produce our product candidates and ACEON on the schedule we require for our clinical trials or to meet commercial requirements may be affected. In addition, contract manufacturers may not perform their obligations under their agreements with us or may discontinue their business before the time required by us to successfully produce clinical and commercial supplies of our product candidates and ACEON.

We and our contract manufacturers are subject to pre-approval inspections and periodic unannounced inspections by the FDA and corresponding state and foreign authorities to ensure strict compliance with cGMP and other applicable government regulations and corresponding foreign standards. We do not have control over a third-party manufacturer’s compliance with these regulations and standards. Any difficulties or delays in our contractors’ manufacturing and supply of our product candidates and ACEON or any failure of our contractors to maintain compliance with the applicable regulations and standards could increase our costs, cause us to lose revenue, make us postpone or cancel clinical trials, prevent or delay regulatory approval by the FDA and corresponding state and foreign authorities, prevent the import and/or export of our product candidates and ACEON, or cause any of our product candidates that may be approved for commercial sale and ACEON to be recalled or withdrawn.

Because many of the companies with which we do business also are in the biotechnology sector, the volatility of that sector can affect us indirectly as well as directly.

 

As a biotechnology company that collaborates with other biotechnology companies, the same factors that affect us directly also can adversely impact us indirectly by affecting the ability of our collaborators, partners and others with which we do business to meet their obligations to us and reduce our ability to realize the value of the consideration provided to us by these other companies.

For example, in connection with our licensing transactions relating to our bacterial cell expression technology, we have in the past and may in the future agree to accept equity securities of the licensee in payment of license fees. The future value of these or any other shares we receive is subject both to market risks affecting our ability to realize the value of these shares and more generally to the business and other risks to which the issuer of these shares may be subject.

As we do more business internationally, we will be subject to additional political, economic and regulatory uncertainties.

 

We may not be able to operate successfully in any foreign market. We believe that because the pharmaceutical industry is global in nature, international activities will be a significant part of our future business activities and when and if we are able to generate income, a substantial portion of that income will be derived from product sales and other activities outside the United States. Foreign regulatory agencies often establish standards different from those in the United States, and an inability to obtain foreign regulatory approvals on a timely basis could put us at a competitive disadvantage or make it uneconomical to proceed with a product or product candidate’s development. International operations and sales may be limited or disrupted by:

 

·

imposition of government controls;

·

export license requirements;

·

political or economic instability;

·

trade restrictions;

·

changes in tariffs;

·

restrictions on repatriating profits;

·

exchange rate fluctuations;

·

withholding and other taxation; and

·

difficulties in staffing and managing international operations.

We are subject to foreign currency exchange rate risks.

 

We are subject to foreign currency exchange rate risks because substantially all of our revenues and operating expenses are paid in U.S. Dollars, but we incur certain expenses, as well as interest and principal obligations with respect to our loan from Servier in Euros. To the extent the U.S. Dollar declines in value against the Euro, the effective cost of servicing our Euro-denominated debt will be higher. Changes in the exchange rate result in foreign currency gains or losses. Although we have managed some of our exposure to changes in foreign currency exchange rates by entering into foreign exchange option contracts, there can be no assurance foreign currency fluctuations will not have a material adverse effect on our business, financial condition, liquidity or results of operations. In addition, our foreign exchange option contracts are re-valued at each financial reporting period, which also may result in gains or losses from time to time.

If we and our partners are unable to protect our intellectual property, in particular our patent protection for our principal products, product candidates and processes, and prevent its use by third parties, our ability to compete in the market will be harmed, and we may not realize our profit potential.

 

We rely on patent protection, as well as a combination of copyright, trade secret, and trademark laws to protect our proprietary technology and prevent others from duplicating our products or product candidates. However, these means may afford only limited protection and may not:

 

·

prevent our competitors from duplicating our products;

·

prevent our competitors from gaining access to our proprietary information and technology; or

·

permit us to gain or maintain a competitive advantage.

Because of the length of time and the expense associated with bringing new products to the marketplace, we and our collaboration and development partners hold and are in the process of applying for a number of patents in the United States and abroad to protect our product candidates and important processes and also have obtained or have the right to obtain exclusive licenses to certain patents and applications filed by others. However, the mere issuance of a patent is not conclusive as to its validity or its enforceability. The U.S. Federal Courts or equivalent national courts or patent offices elsewhere may invalidate our patents or find them unenforceable. In addition, the laws of foreign countries may not protect our intellectual property rights effectively or to the same extent as the laws of the United States. If our intellectual property rights are not protected adequately, we may not be able to commercialize our technologies, products, or services, and our competitors could commercialize our technologies, which could result in a decrease in our sales and market share that would harm our business and operating results. Specifically, the patent position of biotechnology companies generally is highly uncertain and involves complex legal and factual questions. The legal standards governing the validity of biotechnology patents are in transition, and current defenses as to issued biotechnology patents may not be adequate in the future. Accordingly, there is uncertainty as to:

 

 

31

Table of Contents

 

·

whether any pending or future patent applications held by us will result in an issued patent, or that if patents are issued to us, that such patents will provide meaningful protection against competitors or competitive technologies;

·

whether competitors will be able to design around our patents or develop and obtain patent protection for technologies, designs or methods that are more effective than those covered by our patents and patent applications; or

·

the extent to which our product candidates could infringe on the intellectual property rights of others, which may lead to costly litigation, result in the payment of substantial damages or royalties, and/or prevent us from using technology that is essential to our business.

We have established a portfolio of patents, both United States and foreign, related to our bacterial cell expression technology, including claims to novel promoter sequences, secretion signal sequences, compositions and methods for expression and secretion of recombinant proteins from bacteria, including immunoglobulin gene products. Most of the more important European patents in our bacterial cell expression patent portfolio expired in July 2008 or earlier.

 

If certain patents issued to others are upheld or if certain patent applications filed by others issue and are upheld, we may require licenses from others to develop and commercialize certain potential products incorporating our technology or we may become involved in litigation to determine the proprietary rights of others. These licenses, if required, may not be available on acceptable terms, and any such litigation may be costly and may have other adverse effects on our business, such as inhibiting our ability to compete in the marketplace and absorbing significant management time.

 

Due to the uncertainties regarding biotechnology patents, we also have relied and will continue to rely upon trade secrets, know-how and continuing technological advancement to develop and maintain our competitive position. All of our employees have signed confidentiality agreements under which they have agreed not to use or disclose any of our proprietary information. Research and development contracts and relationships between us and our scientific consultants and potential customers provide access to aspects of our know-how that are protected generally under confidentiality agreements. These confidentiality agreements may be breached or may not be enforced by a court. To the extent proprietary information is divulged to competitors or to the public generally, such disclosure may affect our ability to develop or commercialize our products adversely by giving others a competitive advantage or by undermining our patent position.

Litigation regarding intellectual property can be costly and expose us to risks of counterclaims against us.

 

We may be required to engage in litigation or other proceedings to protect our intellectual property. The cost to us of this litigation, even if resolved in our favor, could be substantial. Such litigation also could divert management’s attention and resources. In addition, if this litigation is resolved against us, our patents may be declared invalid, and we could be held liable for significant damages. In addition, we may be subject to a claim that we are infringing another party’s patent. If such claim is resolved against us, we or our collaborators may be enjoined from developing, manufacturing, selling or importing products, processes or services unless we obtain a license from the other party.

Such license may not be available on reasonable terms, thus preventing us from using these products, processes or services and adversely affecting our revenue.

 

We may be unable to price our products effectively or obtain adequate reimbursement for sales of our products, which would prevent our products from becoming profitable.

 

If we or our third-party collaborators or licensees succeed in bringing our product candidates to the market, they may not be considered cost effective, and reimbursement to the patient may not be available or may not be sufficient to allow us to sell our products on a competitive basis. In both the United States and elsewhere, sales of medical products and treatments are dependent, in part, on the availability of reimbursement to the patient from third-party payors, such as government and private insurance plans. Third-party payors are increasingly challenging the prices charged for pharmaceutical products and services. Our business is affected by the efforts of government and third-party payors to contain or reduce the cost of healthcare through various means. In the United States, there have been and will continue to be a number of federal and state proposals to implement government controls on pricing.

In addition, the emphasis on managed care in the United States has increased and will continue to increase the pressure on the pricing of pharmaceutical products. We cannot predict whether any legislative or regulatory proposals will be adopted or the effect these proposals or managed care efforts may have on our business.

Healthcare reform measures and other statutory or regulatory changes could adversely affect our business.

 

In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory proposals to change the healthcare system in ways that could impact our business . In March 2010, the U.S. Congress enacted and President Obama signed into law the PPACA, which includes a number of healthcare reform provisions that are expected to significantly impact the pharmaceutical industry. The PPACA, among other things, imposes a non-deductible annual fee on pharmaceutical manufacturers or importers who sell “branded prescription drugs”; increases the minimum level of Medicaid rebates payable by manufacturers of brand-name drugs from 15.1% to 23.1%; requires collection of rebates for drugs paid by Medicaid managed care organizations; addresses new methodologies by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, and for drugs that are line extension products; and requires manufacturers to participate in a coverage gap discount program, under which they must agree to offer 50% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D. While the law may increase the number of patients who have insurance coverage for our products or product candidates, its cost containment measures also could adversely affect coverage and reimbursement for our existing or potential products; however, the full effects of this law cannot be known until these provisions are implemented and the relevant Federal and state agencies issue applicable regulations or guidance.

Other legislative changes have been proposed and adopted since the PPACA was enacted. On August 2, 2011, the President signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend proposals in spending reductions to Congress. The Joint Select Committee did not achieve its targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic reductions to several government programs. These reductions include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, which went into effect on April 1, 2013. On January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, or the ATRA, which, among other things, further reduced Medicare payments to several providers, including hospitals, imaging centers and cancer treatment centers. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our products once approved or additional pricing pressures, a decrease in the share price of our common stock, limit our ability to raise capital or to obtain strategic collaborations or licenses or successfully commercialize our products.

The pharmaceutical and biotechnology industries are subject to extensive regulation, and from time to time, legislative bodies and governmental agencies consider changes to such regulations that could have significant impact on industry participants. For example, in light of certain highly publicized safety issues regarding certain drugs that had received marketing approval, the U.S. Congress has considered various proposals regarding drug safety, including some that would require additional safety studies and monitoring and could make drug development more costly. We are unable to predict what additional legislation or regulation, if any, relating to safety or other aspects of drug development may be enacted in the future or what effect such legislation or regulation would have on our business.

 

We are exposed to an increased risk of product liability claims.

 

The testing, marketing and sales of medical products entails an inherent risk of allegations of product liability. In the past, we were party to product liability claims filed against Genentech Inc. and, even though Genentech agreed to indemnify us in connection with these matters and these matters have been settled, there can be no assurance other products liability lawsuits will not result in liability to us or that our insurance or contractual arrangements will provide us with adequate protection against such liabilities. In the event of one or more large, unforeseen awards of damages against us, our product liability insurance may not provide adequate coverage. A significant product liability claim for which we were not covered by insurance or indemnified by a third party would have to be paid from cash or other assets, which could have an adverse effect on our business and the value of our common stock. To the extent we have sufficient insurance coverage, such a claim would result in higher subsequent insurance rates. In addition, product liability claims can have various other ramifications, including loss of future sales opportunities, increased costs associated with replacing products, a negative impact on our goodwill and reputation, and divert our management’s attention from our business, each of which could also adversely affect our business and operating results.

The loss of key personnel, including our Chief Executive Officer, could delay or prevent achieving our objectives.

 

Our research, product development and business efforts could be affected adversely by the loss of one or more key members of our scientific or management staff, particularly our executive officers: John Varian, our Chief Executive Officer; Patrick J. Scannon, M.D., Ph.D., our Executive Vice President and Chief Scientific Officer; Fred Kurland, our Vice President, Finance, Chief Financial Officer and Secretary; Paul D. Rubin, M.D., our Senior Vice President, Research and Development and Chief Medical Officer; and Tom Klein, our Vice President and Chief Commercial Officer. We currently do not have key person insurance on any of our employees.

Our ability to use our net operating loss carry-forwards and other tax attributes will be substantially limited by Section 382 of the U.S. Internal Revenue Code.

 

Section 382 of the U.S. Internal Revenue Code of 1986, as amended, generally limits the ability of a corporation that undergoes an “ownership change” to utilize its net operating loss carry-forwards (“NOLs”) and certain other tax attributes against any taxable income in taxable periods after the ownership change. The amount of taxable income in each taxable year after the ownership change that may be offset by pre-change NOLs and certain other pre-change tax attributes is generally equal to the product of (a) the fair market value of the corporation’s outstanding shares (or, in the case of a foreign corporation, the fair market value of items treated as connected with the conduct of a trade or business in the United States) immediately prior to the ownership change and (b) the long-term tax exempt rate (i.e., a rate of interest established by the U.S. Internal Revenue Service (“IRS”) that fluctuates from month to month). In general, an “ownership change” occurs whenever the percentage of the shares of a corporation owned, directly or indirectly, by “5-percent shareholders” (within the meaning of Section 382 of the Internal Revenue Code) increases by more than 50 percentage points over the lowest percentage of the shares of such corporation owned, directly or indirectly, by such “5-percent shareholders” at any time over the preceding three years.

Based on an analysis under Section 382 of the Internal Revenue Code (which subjects the amount of pre-change NOLs and certain other pre-change tax attributes that can be utilized to an annual limitation), the Company experienced ownership changes in 2009 and 2012 which substantially limit the future use of our pre-change NOLs and certain other pre-change tax attributes per year. As of December 31, 2013, the Company has excluded the NOLs and R&D credits that will expire as a result of the annual limitations. To the extent that the Company does not utilize its carry-forwards within the applicable statutory carry-forward periods, either because of Section 382 limitations or the lack of sufficient taxable income, the carry-forwards will also expire unused.

Because we are a relatively small biopharmaceutical company with limited resources, we may not be able to attract and retain qualified personnel.

 

Our success in developing marketable products and achieving a competitive position will depend, in part, on our ability to attract and retain qualified scientific and management personnel, particularly in areas requiring specific technical, scientific or medical expertise. We had approximately 168 employees as of March 10, 2014. We may require additional experienced executive, accounting, research and development, legal, administrative and other personnel from time to time in the future. There is intense competition for the services of these personnel, especially in California. Moreover, we expect that the high cost of living in the San Francisco Bay Area, where our headquarters and manufacturing facilities are located, may impair our ability to attract and retain employees in the future. If we do not succeed in attracting new personnel and retaining and motivating existing personnel, our operations may suffer and we may be unable to implement our current initiatives or grow effectively.

Our business and operations would suffer in the event of system failures.

Despite the implementation of security measures, our internal computer systems and those of our current and any future collaborators, licensees, suppliers, contractors and consultants are vulnerable to damage from cyber−attacks, computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. We could experience failures in our information systems and computer servers, which could be the result of a cyber−attack and could result in an interruption of our normal business operations and require substantial expenditure of financial and administrative resources to remedy. System failures, accidents or security breaches can cause interruptions in our operations and can result in a material disruption of our development programs, commercialization activities and other business operations. The loss of clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Similarly, we rely on third parties to supply components for and manufacture our product and product candidates, conduct clinical trials of our product candidates and warehouse and distribute ACEON, and similar events relating to their computer systems could also have a material adverse effect on our business. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the development of gevokizumab or any of our other product candidates and the commercialization of ACEON could be delayed or otherwise adversely affected.

Calamities, power shortages or power interruptions at our Berkeley headquarters and manufacturing facility could disrupt our business and adversely affect our operations.

 

Our principal operations are located in Northern California, including our corporate headquarters and manufacturing facility in Berkeley, California. This location is in an area of seismic activity near active earthquake faults. Any earthquake, terrorist attack, fire, power shortage or other calamity affecting our facilities may disrupt our business and could have material adverse effect on our business and results of operations.

We have a significant stockholder, which may limit other stockholders’ ability to influence corporate matters and may give rise to conflicts of interest.

Entities controlled by Felix J. Baker and Julian C. Baker beneficially own approximately 26.8% of our outstanding common stock as of March 10, 2014, which includes warrants to purchase approximately 7.6 million shares of XOMA’s common stock at an exercise price of $1.76 per share. On July 19, 2012, our Board of Directors elected Kelvin Neu, M.D., to serve on our Board of Directors. Dr. Neu is a Managing Director at Baker Bros. Advisors, LLC, an entity controlled by Felix J. Baker and Julian C. Baker. Accordingly, these entities may exert significant influence over us and any action requiring the approval of the holders of our stock, including the election of directors and approval of significant corporate transactions. Furthermore, conflicts of interest could arise in the future between us, on the one hand, and these entities, on the other hand, concerning potential competitive business activities, business opportunities, the issuance of additional securities and other matters.

Our organizational documents contain provisions that may prevent transactions that could be beneficial to our stockholders and may insulate our management from removal.

 

Our charter and by-laws:

 

·

require certain procedures to be followed and time periods to be met for any stockholder to propose matters to be considered at annual meetings of stockholders, including nominating directors for election at those meetings; and

·

authorize our Board of Directors to issue up to 1,000,000 shares of preferred stock without stockholder approval and to set the rights, preferences and other designations, including voting rights, of those shares as the Board of Directors may determine.

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”), that may prohibit large stockholders, in particular those owning 15% or more of our outstanding common stock, from merging or combining with us.

These provisions of our organizational documents and the DGCL, alone or in combination with each other, may discourage transactions involving actual or potential changes of control, including transactions that otherwise could involve payment of a premium over prevailing market prices to holders of common stock, could limit the ability of stockholders to approve transactions that they may deem to be in their best interests, and could make it considerably more difficult for a potential acquirer to replace management.

Item 7.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

XOMA discovers and develops innovative antibody-based therapeutics that have unique allosteric modulating properties. Our lead drug candidate, gevokizumab, is a proprietary potent, fully humanized allosteric-modulating monoclonal antibody that binds to the inflammatory cytokine interleukin-1 beta (“IL-1 beta”). We believe that by targeting IL-1 beta, gevokizumab has the potential to address the underlying inflammatory causes of a wide range of diseases that have been identified as having unmet medical needs.

Together with our development partner, Servier (“Servier”), a leading independent French pharmaceutical company, we initiated three Phase 3 clinical trials evaluating gevokizumab for the treatment of non-infectious intermediate, posterior or pan-uveitis (“NIU”) and Behçet’s uveitis, a severe subset of NIU. XOMA is responsible for all of the clinical study sites in the United States, and Servier is responsible for all of the clinical study sites outside of the United States. These studies are known as the EYEGUARD™ program, which includes EYEGUARD-A (patients with active NIU), EYEGUARD-B (patients with Behçet’s uveitis), and EYEGUARD-C (patients currently controlled with systemic treatment).

In addition to the NIU clinical trials, we also are conducting a trial of gevokizumab in pyoderma gangrenosum (“PG”), a rare ulcerative skin disease. Based upon what we believe are compelling data from our pilot study in patients with PG, we requested an End of Phase 2 meeting with the U.S. Food and Drug Administration (“FDA”) to solicit feedback on our proposed Phase 3 clinical development program.  We have been granted a Type B meeting, which we expect to occur in March 2014 and to receive feedback from the FDA early in the second quarter of 2014.

We also have an active gevokizumab Proof-of-Concept (“POC”) development program to identify indications for pivotal development. We conducted POC trials in moderate-to-severe inflammatory acne and in erosive osteoarthritis of the hand (“EOA”), and we have several other ongoing POC studies. In early 2013, we reported top-line results from our moderate-to-severe inflammatory acne study.  Based upon market analysis, we have decided not to pursue a pivotal program in moderate-to-severe inflammatory acne; however, we will consider conducting pilot studies in rare acne indications classified under the umbrella diagnosis of neutrophilic dermatoses.  In October 2013, we reported promising results from the Day 84 pain, stiffness and function endpoints in our gevokizumab POC study in patients with EOA and elevated C-reactive protein (“CRP”), known as Study 160.  At the same time, we announced we completed patient enrollment in a supplemental study for patients with EOA and non-elevated CRP, known as Study 162. On March 4, 2014, we reported that despite early positive results in Study 160, the top-line data at Day 168 in that study, as well as data at Day 84 in Study 162, were not positive.  These results led to our decision not to pursue Phase 3 testing in the broad EOA population.  We will continue to review the data to determine if there is a subgroup of the EOA population that could benefit from gevokizumab therapy.

Gevokizumab has been generally well tolerated across all of our clinical studies.  In both the acne and EOA studies, there were no drug-related serious adverse events reported. The most common adverse events were headache, pain, arthralgia, urinary tract infections, upper respiratory tract infections and pneumonia, and they were comparable between gevokizumab and placebo.

We also have ongoing clinical studies assessing gevokizumab’s potential to treat several other rare diseases. Two studies are being conducted in collaboration with the U.S. National Institutes of Health (“NIH”). In March 2013, we announced that a gevokizumab study in patients with non-infectious anterior scleritis had opened for enrollment at the National Eye Institute (“NEI”). In August 2013, we announced a gevokizumab clinical study in patients with inflammatory autoimmune inner ear disease (“AIED”) run by the North Shore-Long Island Jewish Health System in collaboration with the National Institute on Deafness and Other Communication Disorders (“NIDCD”).

Separately, Servier instituted its own active development program for gevokizumab beyond the NIU and Behçet’s uveitis Phase 3 program. In 2012, Servier initiated a gevokizumab Phase 2 study in patients with acute coronary syndrome, a cardiovascular disease.  In 2013, Servier also began testing gevokizumab in a variety of POC studies, including polymyositis/dermatomyositis, Schnitzler syndrome, and giant cell arteritis. Servier has indicated these are the first studies in an extensive multi-indication exploratory program it expects to conduct.

Our proprietary preclinical pipeline includes classes of allosteric modulating antibodies that activate, sensitize or deactivate the insulin receptor in vivo , which we have named XMet.  This portfolio of antibodies represents potential new therapeutic approaches to the treatment of diabetes and several rare diseases that have insulin involvement.

We have developed these and other antibodies using some or all of our ADAPT™ antibody discovery and development platform, our ModulX™ technologies for generating allosterically modulating antibodies, and our OptimX™ technologies for optimizing biophysical properties of antibodies, including affinity, immunogenicity, stability and manufacturability.

Our biodefense initiatives include XOMA 3AB, a biodefense anti-botulism product candidate comprised of a combination of three antibodies.  XOMA 3AB is directed against botulinum toxin serotype A and has been developed through funding from the National Institute of Allergy and Infectious Diseases (“NIAID”), a part of the NIH. A Phase 1 trial was completed on XOMA 3AB, with no product-related serious adverse events. In January 2012, we announced that we will complete our NIAID biodefense contracts currently in place but will not actively pursue future contracts.  Should the government choose to acquire XOMA 3AB or other biodefense products in the future, we expect to be able to produce these antibodies through an outside manufacturer.

We also have developed antibody product candidates with premier pharmaceutical companies including Novartis AG (“Novartis”) and Takeda Pharmaceutical Company Limited (“Takeda”).  Two antibodies developed with Novartis, LFA102 and HCD122 (lucatumumab), are in clinical development by Novartis.

Significant Developments in 2013

Gevokizumab

·

In January 2013, we announced preliminary top-line data from an interim analysis of our Phase 2 proof-of-concept study to evaluate the safety and efficacy of gevokizumab for the treatment of moderate-to-severe inflammatory acne. Preliminary data from the 125-patient trial demonstrated clear activity according to the Investigator’s Global Assessment (“IGA”) parameter. Gevokizumab was well-tolerated in this trial, with no significant differences in adverse events between gevokizumab and placebo and no serious drug-related adverse events were reported. Based upon market analysis, we have decided not to pursue a pivotal program in moderate-to-severe inflammatory acne; however, we will consider conducting pilot studies in rare acne indications classified under the umbrella diagnosis of neutrophilic dermatoses.

·

In April 2013, the NEI opened a non-infectious, active, anterior scleritis trial for patient enrollment. The open-label single-arm Phase 1/2 study is designed to assess the safety and potential efficacy of gevokizumab in patients experiencing non-infectious, active, anterior scleritis, which is the inflammation of the sclera.

·

In May 2013, we announced we had initiated a second clinical study in inflammatory osteoarthritis of the hand based upon our findings that patients who met all of the eligibility criteria for our original study were not able to participate due to the requirement C-reactive protein (CRP) levels must be greater than or equal to 2.5 mg/L.  This second study has the same design and eligibility requirements with the exception that participants with a CRP level of less than 2.5 mg/L may enroll. The study is capturing the same pain and functional endpoints as the primary study, yet the design does not include radiographic/MRI images of the affected joints.

·

In June 2013, we opened enrollment in an open-label pilot study to determine gevokizumab's potential to treat acute inflammatory PG. In October 2013, we announced compelling data from our pilot study in patients with PG, and we have requested a meeting with the FDA to solicit feedback regarding PG as a potential indication for gevokizumab in Phase 3 trials.

·

In June 2013, Servier launched its own independent proof-of-concept clinical program to evaluate the safety and efficacy of gevokizumab in indications different from ours.  The first such studies are in polymyositis/dermatomyositis, Schnitzler syndrome, and giant cell arteritis.

·

In July 2013, we announced the completion of patient enrollment in our Phase 2 proof-of-concept study in EOA.

·

In August 2013, we announced that a gevokizumab clinical study in patients with AIED will be conducted by the North Shore-Long Island Jewish Health System in collaboration with the National Institute on Deafness and Other Communication Disorders.

·

In October 2013, we announced three-month results from our gevokizumab Phase 2 clinical study in patients with EOA who also have CRP levels greater than or equal to 2.5 mg/L. The three-month results demonstrated that gevokizumab has a clinical effect on the target patient population. On March 4, 2014, we reported that despite early positive results in the first Study, the top-line data at Day 168 in that study, as well as data at Day 84 in the second study, were not positive.  These results led to our decision not to pursue Phase 3 testing in the broad EOA population. We will continue to review the data to determine if there is a subgroup of the EOA population that could benefit from gevokizumab therapy.

Perindopril Franchise

·

In July 2013, we transferred U.S. development and commercialization rights to the perindopril franchise to Symplmed Pharmaceuticals, LLC (“Symplmed”). Under the terms of the arrangement, we received a minority equity position in Symplmed and up to double-digit royalties on sales of the first fixed-dose combination containing perindopril arginine and amlodipine besylate, if it is approved by the FDA. We recorded the minority equity position in the other assets line of our consolidated balance sheets. Symplmed, under a sublicense agreement, assumes U.S. marketing responsibilities for ACEON (perindopril erbumine), and we continue to manage and be reimbursed for sales and distribution within our established commercial infrastructure until the ACEON New Drug Application (“NDA”) is transferred to Symplmed. The ACEON NDA was to be transferred on March 1, 2014, but Symplmed has requested an extension. Terms of an extension agreement, if any, are being negotiated. We will continue to record gross ACEON sales in the contracts and other revenue line of our consolidated statements of comprehensive loss until the ACEON NDA is transferred. Following the ACEON NDA transfer, Symplmed will pay us single-digit royalties on sales of ACEON.

Management Addition

·

On March 18, 2013, the Company announced Tom Klein has joined the Company as Vice President, Chief Commercial Officer, a newly created position reporting to John Varian, Chief Executive Officer.

Financing

·

In August 2013, we completed an underwritten public offering of 8,736,187 shares of our common stock for gross proceeds of $31.6 million, before deducting underwriting discounts and commissions and estimated offering expenses totaling approximately $2.2 million.

·

In December 2013, we completed an underwritten public offering of 10,925,000 shares of our common stock for gross proceeds of $57.4 million, before deducting underwriting discounts and commissions and estimated offering expenses totaling approximately $3.8 million.

Other

·

In December 2013, we received a milestone payment of $7.0 million from Novartis under the 2008 Amended and Restated Research, Development and Commercialization Agreement between Novartis and XOMA (US) LLC, in connection with the clinical advancement of an undisclosed product in an undisclosed indication. Pursuant to our obligations under the Agreement, in January 2014, we made a payment, equal to 25 percent of the milestone received, or $1.75 million, toward our outstanding debt obligation to Novartis.

Critical Accounting Estimates

The accompanying discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements and the related disclosures, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts in our consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

The consolidated financial statements include the accounts of XOMA and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

We believe the following policies to be the most critical to an understanding of our financial condition and results of operations because they require us to make estimates, assumptions and judgments about matters that are inherently uncertain.

Revenue Recognition

License and Collaborative Fees

Revenue from non-refundable license, technology access or other payments under license and collaborative agreements where we have a continuing obligation to perform is recognized as revenue over the expected period of the continuing performance obligation. We estimate the performance period at the inception of the arrangement and re-evaluate it each reporting period. This re-evaluation may shorten or lengthen the period over which the remaining revenue is recognized. Changes to these estimates are recorded on a prospective basis.

Milestone payments under collaborative and other arrangements are recognized as revenue upon completion of the milestone event, once confirmation is received from the third party and collectability is reasonably assured. This represents the culmination of the earnings process because we have no future performance obligations related to the payment. Milestone payments that require a continuing performance obligation on our part are recognized over the expected period of the continuing performance obligation. Amounts received in advance are recorded as deferred revenue until the related milestone is completed.

Contract Revenue

Contract revenue for research and development involves our providing research and development and manufacturing services to collaborative partners, biodefense contractors or others. Revenue for certain contracts is accounted for by a proportional performance, or output-based, method where performance is based on estimated progress toward elements defined in the contract. The amount of contract revenue and related costs recognized in each accounting period are based on estimates of the proportional performance during the period. Adjustments to estimates based on actual performance are recognized on a prospective basis and do not result in reversal of revenue should the estimate to complete be extended.

In addition, revenue related to certain research and development contracts is billed based on actual hours incurred by XOMA related to the contract, multiplied by full-time equivalent (“FTE”) rates plus a mark-up. The FTE rates are developed based on our best estimates of labor, materials and overhead costs. For certain contracts, such as our government contracts, the FTE rates are agreed upon at the beginning of the contract and are subject to review or audit by the contracting party at any time. Under our contracts with NIAID, a part of the NIH, we bill using NIH provisional rates and thus are subject to future audits at the discretion of NIAID’s contracting office. These audits can result in adjustments to previously reported revenue.

In 2011, the NIH conducted an audit of our actual data under two contracts for the period from January 1, 2007, through December 31, 2009, and developed final billing rates for this period. As a result, we retroactively applied these NIH rates to the invoices from this period which resulted in an increase in revenue of $3.1 million from the NIH, excluding $0.9 million billed to the NIH in 2010 resulting from our performance of a comparison of 2009 calculated costs incurred and costs billed to the government under provisional rates. Final rates were settled for one contract resulting in the recognition of revenue of $2.0 million in 2012. The remaining contract will be settled through negotiations with the NIH. This revenue has been deferred and will be recognized upon completion of negotiations with and approval by the NIH.

Upfront fees are recognized ratably over the expected benefit period under the arrangement. Given the uncertainties of research and development collaborations, significant judgment is required to determine the duration of the arrangement.

Stock-based Compensation

The valuation of stock-based compensation awards is determined at the date of grant using the Black-Scholes option pricing model (the “Black-Scholes Model”). This model requires inputs such as the expected term of the option, expected volatility, and risk-free interest rate. Further, the forfeiture rate also impacts the amount of aggregate compensation. These inputs are subjective and generally require significant analysis and judgment to develop. To establish an estimate of expected term, we consider the vesting period and contractual period of the award and our historical experience of stock option exercises, post-vesting cancellations and volatility. To establish an estimate of forfeiture rate, we consider our historical experience of option forfeitures and terminations. The risk-free rate is based on the yield available on United States Treasury zero-coupon issues. We review our valuation assumptions quarterly and, as a result, it is likely we will change our valuation assumptions used to value stock-based awards granted in future periods. Stock-based compensation expense is recognized ratably over the requisite service period.

Income Taxes

We account for uncertain tax positions in accordance with Accounting Standards Codification Topic 740, Income Taxes ("ASC 740").  The application of income tax law and regulations is inherently complex.  Interpretations and guidance surrounding income tax laws and regulations change over time.  As such, changes in our subjective assumptions and judgments can materially affect amounts recognized in our financial statements.

ASC 740 provides for the recognition of deferred tax assets if realization of such assets is more likely than not.  Based upon the weight of available evidence, which includes our historical operating performance and carry-back potential, we have determined that total deferred tax assets should be fully offset by a valuation allowance.

Warrants

We have issued warrants to purchase shares of our common stock in connection with financing activities. We account for some of these warrants as a liability at fair value and others as equity at fair value. The fair value of the outstanding warrants is estimated using the Black-Scholes Model. The Black-Scholes Model requires inputs such as the expected term of the warrants, expected volatility and risk-free interest rate. These inputs are subjective and require significant analysis and judgment to develop. For the estimate of the expected term, we use the full remaining contractual term of the warrant. We base our estimate of expected volatility on our historical stock price volatility. The assumptions associated with contingent warrant liabilities are reviewed each reporting period and changes in the estimated fair value of these contingent warrant liabilities are recognized in other income (expense).

Results of Operations

Revenue

Total revenues for the years ended December 31, 2013, 2012, and 2011, were as follows (in thousands):

		Year ended December 31,												2012-2013				2011-2012
		2013				2012				2011				Increase (Decrease)				Increase (Decrease)
License and collaborative fees		$	11,028			$	5,727			$	17,991			$	5,301			$	(12,264	)
Contract and other revenue			24,423				28,055				40,205				(3,632	)			(12,150	)
Total revenues		$	35,451			$	33,782			$	58,196			$	1,669			$	(24,414	)

License and Collaborative Fees

License and collaborative fee revenue includes fees and milestone payments related to the out-licensing of our products and technologies. The primary components of license and collaboration fee revenue in 2013 were $8.6 million in milestone payments relating to various out-licensing arrangements, including a $7.0 million milestone payment from Novartis, $0.8 million in upfront fees and annual maintenance fees relating to various out-licensing arrangements, and $1.6 million in revenue recognized related to the loan agreement with Servier.

The primary components of license and collaboration fee revenue in 2012 were $3.3 million in upfront fees and annual maintenance fees relating to various out-licensing arrangements, $1.4 million in revenue recognized related to the loan agreement with Servier, and $1.0 million recognized for six milestone payments.

The primary components of license and collaboration fee revenue in 2011 were $16.2 million in revenue recognized related to the collaboration and loan agreements with Servier to jointly develop and commercialize gevokizumab in multiple indications. In addition, we recognized two milestone payments for an aggregate amount of $1.0 million and $0.8 million in up-front fees and annual maintenance fees relating to various out-licensing arrangements.

The generation of future revenue related to license fees and collaborative arrangements is dependent on our ability to attract new licensees to our antibody and proprietary technologies and new collaboration partners. We expect an increase in license and collaboration fee revenue in 2014 compared to 2013 levels.

Contract and Other Revenue

Contract and other revenues include agreements where we provide contracted research and development services to our contract and collaboration partners, including Servier and NIAID. Contract and other revenues also include net product sales and royalties. The following table shows the activity in contract and other revenue for the years ended December 31, 2013, 2012, and 2011 (in thousands):

Total revenues		$	24,423			$	28,055			$	40,205			$	(3,632	)		$	(12,150	)

The 2013 decrease in contract and other revenue, as compared to 2012, was primarily due to the 2012 recognition of $2.0 million in revenue related to an adjustment to previously reported revenue from NIAID resulting from an audit by NIAID’s contracting office. Also contributing to the decrease were decreases of $1.4 million in CMC activity and $0.6 million in gevokizumab clinical development activity under our collaboration with Servier, partially offset by a $0.9 million increase in partial funding received from Servier for the FDC1 Phase 3 trial.

The 2012 decrease in contract and other revenue, as compared to 2011, was primarily due to decreased activity under NIAID Contract No. HHSN272200800028C (“NIAID 3”). This decrease of $12.0 million in NIAID 3 revenue was partially offset by the recognition of $2.0 million in revenue related to an adjustment to previously reported revenue from NIAID resulting from an audit by NIAID’s contracting office. This revenue, which was previously deferred, was recognized upon the completion of negotiations with and approval by the NIH in March 2012. Also partially offsetting the decreases in NIAID revenue was a $2.4 million increase in activity under Contract No. HHSN272201100031C (“NIAID 4”). The NIAID 4 contract was executed in October 2011. In addition, a reduction in CMC activity under the collaboration with Servier contributed to the decrease in contract and other revenue in 2012, as compared to 2011, partially offset by an increase in gevokizumab clinical development activity under the collaboration with Servier and the recognition of partial funding received from Servier for the FDC1 Phase 3 trial.

We expect contract and other revenue to decrease in 2014 compared to 2013 levels. Revenue generating activity related to our Servier contract is expected to be reduced due to the collaboration reaching the $50 million fully reimbursable cap for NIU expenses.

The following table shows the activity in deferred revenue for the years ended December 31, 2013, 2012, and 2011 (in thousands):

		Year ended December 31,
		2013				2012				2011
Beginning deferred revenue		$	9,724			$	13,234			$	18,130
Revenue deferred			1,478				5,881				12,673
Revenue recognized			(4,879	)			(9,391	)			(17,569	)
Ending deferred revenue		$	6,323			$	9,724			$	13,234

We defer revenue until all requirements under our revenue recognition policy are met. In 2013, we deferred revenue from contracts including Servier and NIAID. In 2012 and 2011, we deferred revenue from contracts including Servier, NIH and Takeda.

We expect a significant portion of the $6.3 million in deferred revenue to be recognized in 2014 with the remainder to be earned during 2015. Future amounts may be affected by additional consideration received, if any, under existing or any future licensing or other collaborative arrangements as well as changes in the estimated period of obligation or services to be provided under the arrangements.

Research and Development Expenses

Biopharmaceutical development includes a series of steps, including in vitro and in vivo preclinical testing, and Phase 1, 2 and 3 clinical studies in humans. Each of these steps is typically more expensive than the previous step, but actual timing and the cost to us depends on the product being tested, the nature of the potential disease indication and the terms of any collaborative or development arrangements with other companies or entities. After successful conclusion of all of these steps, regulatory filings for approval to market the products must be completed, including approval of manufacturing processes and facilities for the product. Our research and development expenses currently include costs of personnel, supplies, facilities and equipment, consultants, other third-party costs and expenses related to preclinical and clinical testing.

Research and development expenses were $74.9 million in 2013, compared with $68.5 million in 2012 and $68.1 million in 2011. The increase of $6.4 million in 2013, compared to 2012, was primarily due to higher external manufacturing activity, internal proprietary project costs, and salaries and related personnel costs, partially offset by decreases in FDC clinical trial costs, and internal facility costs as a result of the 2012 streamlining of operations. Clinical trial costs increased in 2012, as compared to 2011, however, this increase was offset by decreases in salaries and related personnel costs.

Salaries and related personnel costs are a significant component of research and development expenses. We recorded $27.0 million in research and development salaries and employee-related expenses in 2013, compared with $25.9 million in 2012 and $34.3 million in 2011. Included in these expenses for 2013 were $21.7 million for salaries and benefits, $2.9 million for bonus expense and $2.4 million for stock-based compensation, which is a non-cash expense. The increase in 2013, as compared to 2012, was primarily due to an increase in salaries and benefits of $0.9 million resulting from increased headcount.

Included in these expenses for 2012 were $20.8 million for salaries and benefits, $2.7 million for bonus expense and $2.4 million for stock-based compensation, which is a non-cash expense. The decrease in 2012, as compared to 2011, was primarily due to a decrease in salaries and benefits of $6.9 million resulting from decreased headcount in manufacturing as result of the 2012 streamlining of operations, and a $1.3 million decrease in stock-based compensation.

Our research and development activities can be divided into earlier-stage programs and later-stage programs. Earlier-stage programs include molecular biology, process development, pilot-scale production and preclinical testing. Also included in earlier-stage programs are costs related to excess manufacturing capacity. We expect excess manufacturing capacity to continue to decrease in 2014 compared to 2013 due to our streamlining objective implemented in 2012 to utilize a contract manufacturing organization. Later-stage programs include clinical testing, regulatory affairs and manufacturing clinical supplies. The costs associated with these programs approximate the following (in thousands):

 

		Year ended December 31,
		2013				2012				2011
Earlier stage programs (1)		$	40,840			$	33,170			$	38,302
Later stage programs (1)			34,011				35,297				29,835
Total		$	74,851			$	68,467			$	68,137

Certain research and development segment reclassifications have been made to previously reported amounts to conform to the current year's presentation.

Our research and development activities also can be divided into those related to our internal projects and those projects related to collaborative and contract arrangements. The costs related to internal projects versus collaborative and contract arrangements approximate the following (in thousands):

		Year ended December 31,
		2013				2012				2011
Internal projects (1)		$	47,489			$	30,531			$	24,440
Collaborative and contract arrangements (1)			27,362				37,936				43,697
Total		$	74,851			$	68,467			$	68,137

Certain research and development segment reclassifications have been made to previously reported amounts to conform to the current year's presentation.

In 2013, the gevokizumab program, for which we incurred the largest amount of expense, accounted for more than 40% but less than 50% of our total research and development expenses. A second development program, XMet, accounted for more than 20% but less than 30% of our total research and development expenses and a third development program, NIAID, accounted for more than 10% but less than 20% of our total research and development expenses. In 2012, the gevokizumab program, for which we incurred the largest amount of expense, accounted for more than 40% but less than 50% of our total research and development expenses. NIAID, accounted for more than 20% but less than 30% of our total research and development expenses and XMet, accounted for more than 10% but less than 20% of our total research and development expenses. In 2011, each of the two programs upon which we incurred the largest amount of expense, gevokizumab and NIAID, accounted for more than 30% but less than 40% of our total research and development expenses. All remaining development programs accounted for less than 10% of our total research and development expense in 2013, 2012, and 2011.

Table of Contents

We expect our research and development spending in 2014 will increase primarily due to our ongoing global Phase 3 clinical program for gevokizumab for the NIU indications, under our license and collaboration agreement with Servier, our ongoing gevokizumab Phase 2 proof-of-concept program, and the continued development of our XMet program.

Future research and development spending also may be impacted by potential new licensing or collaboration arrangements, as well as the termination of existing agreements. Beyond this, the scope and magnitude of future research and development expenses are difficult to predict at this time.

Selling, General and Administrative Expenses

Selling, general and administrative expenses include salaries and related personnel costs, facilities costs and professional fees. In 2013, selling, general and administrative expenses were $18.5 million compared with $16.9 million in 2012 and $24.0 million in 2011. The increase in selling, general and administrative expenses in 2013 as compared with 2012 primarily was due to increases in consulting services of $1.3 million, primarily reflecting investments in market research activities made during 2013, and salaries and related personnel costs of $0.5 million, partially offset by a decrease in profession service costs of $0.6 million.

The decrease in selling, general and administrative expenses in 2012 as compared with 2011 primarily was due to decreases in salaries and related personnel costs of $3.8 million in large part due to the one-time $1.3 million severance expense and a $0.7 million stock-based compensation charge incurred during the third quarter of 2011 in connection with the resignation of our former Chairman, Chief Executive Officer and President, and a decrease in other stock-based compensation of $1.5 million. Also contributing to these changes were decreases in legal costs and consulting fees of $1.8 million and $1.4 million, respectively.

We expect selling, general and administrative expenses in 2014 to be comparable to 2013 levels.

Streamlining and Restructuring Charges

In January 2012, we implemented a streamlining of operations, which resulted in a restructuring plan designed to sharpen our focus on value-creating opportunities led by gevokizumab and its unique antibody discovery and development capabilities. The restructuring plan included a reduction of XOMA’s personnel by 84 positions, or 34%. These staff reductions resulted primarily from our decisions to utilize a contract manufacturing organization for Phase 3 and commercial antibody production, and to eliminate internal research functions that are non-differentiating or that can be obtained cost effectively by contract service providers.

In connection with the streamlining of operations, we incurred restructuring charges in 2012 of $2.0 million related to severance, other termination benefits and outplacement services, $2.2 million related to the impairment and accelerated depreciation of various assets and leasehold improvements, and $0.7 million related to moving and other facility costs. In 2013, we incurred $0.3 million in restructuring charges related to facility costs and we do not expect to incur additional significant restructuring charges during 2014 related to these streamlining activities.

Table of Contents

The increased interest expense in 2013 as compared to 2012 was due primarily to an increase in the principal of the GECC term loan, which was amended in September 2012.

The increased interest expense in 2012 as compared to 2011 was due primarily to interest expense related to the loan with GECC, which was funded in December 2011 and amended in September 2012.

The increased interest expense in 2011 as compared to 2010 was due primarily to interest expense related to the loan with Servier, which was funded in January 2011.

Other Expense

Other expense primarily consisted of unrealized (losses) gains. The following table shows the activity in other expense for the years ended December 31, 2013, 2012, and 2011 (in thousands):

(1)	Unrealized foreign exchange loss for the years ended December 31, 2013, 2012, and 2011 primarily relates to the re-measurement of the €15 million Servier loan.

(2)	Realized foreign exchange gain for the year ended December 31, 2011 primarily relates to the conversion into U.S. dollars of the €15 million cash proceeds received from Servier in January of 2011.

Revaluation of Contingent Warrant Liabilities

In March 2012, in connection with an underwritten offering, we issued five-year warrants to purchase 14,834,577 shares of XOMA’s common stock at an exercise price of $1.76 per share. These warrants contain provisions that are contingent on the occurrence of a change in control, which would conditionally obligate us to repurchase the warrants for cash in an amount equal to their fair value using the Black-Scholes Option Pricing Model (the “Black-Scholes Model”) on the date of such change in control. Due to these provisions, we are required to account for the warrants issued in March 2012 as a liability at fair value. In addition, the estimated liability related to the warrants is required to be revalued at each reporting period until the earlier of the exercise of the warrants, at which time the liability will be reclassified to stockholders' equity, or expiration of the warrants. At December 31, 2012, the fair value of the warrant liability was estimated to be $15.0 million using the Black-Scholes Model. We revalued the warrant liability at December 31, 2013 using the Black-Scholes Model and recorded the $59.9 million increase in the fair value as a loss in the revaluation of contingent warrant liabilities line of our consolidated statements of comprehensive loss. We also reclassified $6.2 million from contingent warrant liabilities to equity on our consolidated balance sheets due to the exercise of warrants. As of December 31, 2013, 12,562,682 of these warrants were outstanding and had a fair value of $68.7 million. This increase in liability is due primarily to the increase in the market price of XOMA’s common stock at December 31, 2013 compared to December 31, 2012.

In February 2010, in connection with an underwritten offering, we issued five-year warrants to purchase 1,260,000 shares of XOMA’s common stock at an exercise price of $10.50 per share. In June 2009, we issued warrants to certain institutional investors as part of a registered direct offering. These warrants represent the right to acquire an aggregate of up to 347,826 shares of XOMA’s common stock over a five year period beginning December 11, 2009 at an exercise price of $19.50 per share. These warrants contain provisions that are contingent on the occurrence of a change in control, which would conditionally obligate us to repurchase the warrants for cash in an amount equal to their fair value using the Black-Scholes Model on the date of such change in control. Due to these provisions, we are required to account for the warrants issued in February 2010 and June 2009 as liabilities at fair value. At December 31, 2012, the fair value of the warrant liability was estimated to be $0.1 million using the Black-Scholes Model. We revalued the warrant liability at December 31, 2013 using the Black-Scholes Model and recorded the $1.1 million increase in the fair value as a loss in the revaluation of contingent warrant liabilities line of our consolidated statements of comprehensive loss. As of December 31, 2013, all of these warrants were outstanding and had an aggregate fair value of approximately $1.2 million.

Income Taxes

There was no material income tax expense for the years ended December 31, 2013, 2012, and 2011.  The income tax benefit in 2013 and 2012 primarily relates to federal refundable credit true-ups from prior years.

Accounting Standards Codification Topic 740, Income Taxes ("ASC 740") provides for the recognition of deferred tax assets if realization of such assets is more likely than not.  Based upon the weight of available evidence, which includes our historical operating performance and carry-back potential, we have determined that total deferred tax assets should be fully offset by a valuation allowance.

We have recorded cumulative gross deferred tax assets of $160.1 million and $234.1 million at December 31, 2013 and 2012, respectively, principally attributable to the timing of the deduction of certain expenses associated with certain research and development expenses, net operating loss and other carry-forwards. We also recorded corresponding valuation allowances of $160.1 million and $234.1 million at December 31, 2013 and 2012, respectively, to offset these deferred tax assets, as management cannot predict with reasonable certainty that the deferred tax assets to which the valuation allowances relate will be realized.

As of December 31, 2013, we had federal net operating loss carry-forwards (“NOLs”) of approximately $205.0 million and state net operating loss carry-forwards of approximately $164.0 million to offset future taxable income. We also had federal research and development tax credit carry-forwards of approximately $0.4 million and state research and development tax credit carry-forwards of approximately $16.5 million.

Based on an analysis under Section 382 of the Internal Revenue Code (which subjects the amount of pre-change NOLs and certain other pre-change tax attributes that can be utilized to an annual limitation), we experienced ownership changes in 2009 and 2012 which substantially limit the future use of our pre-change NOLs and certain other pre-change tax attributes per year. We have excluded the NOLs and R&D credits that will expire as a result of the annual limitations in the deferred tax assets as of December 31, 2013. To the extent that we do not utilize our carry-forwards within the applicable statutory carry-forward periods, either because of Section 382 limitations or the lack of sufficient taxable income, the carry-forwards will expire unused.

We do not expect the unrecognized tax benefits to change significantly over the next twelve months. We will recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.  As of December 31, 2013, we have not accrued interest or penalties related to uncertain tax positions.

Working Capital

 

The increase in working capital in 2013 as compared to 2012 was primarily due to the completion of two equity offerings in 2013 contributing to a $36.3 million increase in cash, cash equivalents, and short-term investments, partially offset by a decrease in fourth quarter billable revenue under our collaboration with Servier and an increase in external manufacturing costs and spending on internal proprietary projects.

Cash Used in Operating Activities

The increase in net cash used in operating activities in 2013 as compared to 2012 was primarily due to an increase in research and development spending relating to external manufacturing costs and internal proprietary projects.

The increase in net cash used in operating activities in 2012 as compared to 2011 was primarily due to a $15.0 million license fee received in the first quarter of 2011 as consideration for the collaboration with Servier. This cash receipt in 2011 was partially offset by a $2.0 million increase in cash receipts in 2012 as a result of the timing under our collaboration agreement with Servier.

We expect net cash used in operating activities in 2014 to increase compared to 2013 levels due to increased spending on clinical trials.

Cash Used in Investing Activities

Cash provided by investing activities for the year ended December 31, 2013, consisted of $40.0 million in proceeds from maturities of short-term investments, partially offset by purchases of short-term investments of $20.0 million and fixed asset purchases of $1.2 million. Cash used in investing activities for the year ended December 31, 2012, consisted of purchases of short-term investments of $57.0 million and fixed asset purchases of $2.5 million, partially offset by $17.0 million in proceeds from maturities of short-term investments and $0.5 million in proceeds from the sale of fixed assets. Cash used in investing activities for the years ended December 31, 2011, primarily consisted of fixed asset purchases.

Cash Provided by Financing Activities

Net cash provided by financing activities for the year ended December 31, 2013, was primarily related to net proceeds received from the issuance of common stock of $29.4 million from the August 2013 public offering, $53.6 million from the December 2013 public offering, $2.2 million of net proceeds from the exercise of warrants, and $1.4 million of net proceeds received from employee stock purchases. These net proceeds were partially offset by $3.1 million of principal payments on our loan with GECC.

Net cash provided by financing activities for the year ended December 31, 2012, was primarily related to net proceeds received from the issuance of common stock of $77.5 million, including net proceeds of $36.2 million from the March 2012 underwritten public offering, net proceeds of $37.0 million from the October 2012 underwritten public offering, net proceeds of $3.2 million received from the issuance of common stock under the 2011 ATM Agreement, net proceeds of $1.0 million from the exercise of warrants issued as part of the March 2012 underwritten public offering, and net proceeds of $0.2 million from the exercise of outstanding options. Also contributing to net cash provided by financing activities was net loan proceeds of $4.4 million received from GECC, partially offset by $2.1 million principal payments on our loan with GECC.

Table of Contents

Net cash provided by financing activities for the year ended December 31, 2011, was primarily related to loan proceeds of $20.1 million received from Servier, issuance of shares of our common stock for $15.1 million under the 2010 and 2011 ATM agreements, and loan proceeds of $10.0 million received from GECC. The loan proceeds from GECC were partially offset by debt issuance costs of $1.3 million.

Registered Direct Offerings

In June of 2009, we entered into a definitive agreement with certain institutional investors to sell 695,652 units, with each unit consisting of one share of our common stock and a warrant to purchase 0.50 of a share of our common stock, for gross proceeds of approximately $12.0 million, before deducting placement agent fees and estimated offering expenses of $0.8 million, in a second registered direct offering. The investor purchased the units at a price of $17.25 per unit. The warrants, which represent the right to acquire an aggregate of up to 347,826 shares of common stock, are exercisable at any time on or prior to December 10, 2014 at an exercise price of $19.50 per share. As of December 31, 2013 all of these warrants were outstanding.

ATM Agreements

In the third quarter of 2010, we entered into the 2010 ATM Agreement, with Wm Smith and MLV (the “Agents”), under which we could sell shares of our common stock from time to time through the Agents, as our agents for the offer and sale of the shares, in an aggregate amount not to exceed the amount that can be sold under our registration statement on Form S-3 (File No. 333-148342) filed with the Securities and Exchange Commission (the “SEC”) on December 26, 2007, and declared effective by the SEC on May 29, 2008. The Agents could sell the shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), including without limitation sales made directly on The NASDAQ Global Market, on any other existing trading market for our common stock or to or through a market maker. The Agents could also sell the shares in privately negotiated transactions, subject to our prior approval. From the inception of the 2010 ATM Agreement through May of 2011, we sold a total of 7,560,862 shares of our common stock under this agreement for aggregate gross proceeds of $34.0 million, including 821,386 shares sold in 2011 for aggregate gross proceeds of $4.4 million. Total offering expenses incurred related to sales under the 2010 ATM Agreement from inception to May of 2011 were $1.0 million, including $0.1 million incurred in 2011. In May of 2011, 2010 ATM Agreement expired by its terms, and there will be no further issuances under this facility.

On February 4, 2011, we entered into an At Market Issuance Sales Agreement (the “2011 ATM Agreement”), with McNicoll, Lewis & Vlak LLC (now known as MLV & Co. LLC, “MLV”), under which we may sell shares of our common stock from time to time through MLV, as our agent for the offer and sale of the shares, in an aggregate amount not to exceed the amount that can be sold under our registration statement on Form S-3 (File No. 333-172197) filed with the SEC on February 11, 2011, and amended on March 10, 2011, June 3, 2011, and January 3, 2012, which was most recently declared effective by the SEC on January 17, 2012.  MLV may sell the shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act, including without limitation sales made directly on The NASDAQ Global Market, on any other existing trading market for our common stock or to or through a market maker.  MLV also may sell the shares in privately negotiated transactions, subject to our prior approval.  We will pay MLV a commission equal to 3% of the gross proceeds of the sales price of all shares sold through it as sales agent under the 2011 ATM Agreement. From the inception of the 2011 ATM Agreement through December 31, 2013, we sold a total of 7,572,327 shares of common stock under this agreement for aggregate gross proceeds of $14.6 million. No shares of common stock have been sold under this agreement since February 3, 2012. Total offering expenses incurred related to sales under the 2011 ATM Agreement from inception to December 31, 2013, were $0.5 million. The registration statement under which the 2011 ATM was entered expires in June of 2014.

Underwritten Offerings

In February 2010, we completed an underwritten offering of 2.8 million units, with each unit consisting of one shares of our common stock and a warrant to purchase 0.45 of a share of our common stock, for gross proceeds of approximately $21.0 million, before deducting underwriting discounts and commissions and estimated offering expenses of $1.7 million.  The warrants, which represent the right to acquire an aggregate of up to 1.26 million shares of our common stock, are exercisable beginning six months and one day after issuance and have a five-year term and an exercise price of $10.50 per share. As of December 31, 2013, all of these warrants were outstanding.

On March 9, 2012, we completed an underwritten public offering of 29,669,154 shares of our common stock, and accompanying warrants to purchase one half of a share of common stock for each share purchased, at a public offering price of $1.32 per share. Total gross proceeds from the offering were approximately $39.2 million, before deducting underwriting discounts and commissions and offering expenses totaling approximately $3.0 million. The warrants, which represent the right to acquire an aggregate of up to 14,834,577 shares of common stock, are exercisable immediately and have a five-year term and an exercise price of $1.76 per share. As of December 31, 2013, 12,562,682 of these warrants were outstanding.

Total gross proceeds from the offering were approximately $40.0 million, before deducting underwriting discounts and commissions and offering expenses totaling approximately $3.0 million.

On August 23, 2013, we completed an underwritten public offering of 8,736,187 shares of our common stock, including 1,139,502 shares of our common stock that were issued upon the exercise of the underwriters’ 30-day over-allotment option, at a public offering price of $3.62 per share. Total gross proceeds from the offering were approximately $31.6 million, before deducting underwriting discounts and commissions and estimated offering expenses totaling approximately $2.2 million.

On December 18, 2013, we completed an underwritten public offering of 10,925,000 shares of our common stock, including 1,425,000 shares of our common stock that were issued upon the exercise of the underwriters’ 30-day over-allotment option, at a public offering price of $5.25 per share. Total gross proceeds from the offering were approximately $57.4 million, before deducting underwriting discounts and commissions and estimated offering expenses totaling approximately $3.8 million.

Servier Loan

In December 2010, we entered into a loan agreement with Servier (the “Servier Loan Agreement”), which provided for an advance of up to €15.0 million. The loan was fully funded in January 2011, with the proceeds converting to approximately $19.5 million at the date of funding. The loan is secured by an interest in XOMA’s intellectual property rights to all gevokizumab indications worldwide, excluding certain rights in the U.S. and Japan. Interest is calculated at a floating rate based on a Euro Inter-Bank Offered Rate (“EURIBOR”) and is subject to a cap. The interest rate is reset semi-annually in January and July of each year. The interest rate for the initial interest period was 3.22% and was reset semi-annually ranging from 2.33% to 3.83%. Interest for the six-month period from January 2014 through July 2014 was reset to 2.39%. Interest is payable semi-annually; however, the Servier Loan Agreement provides for a deferral of interest payments over a period specified in the agreement. During the deferral period, accrued interest will be added to the outstanding principal amount for the purpose of interest calculation for the next six-month interest period. On the repayment commencement date, all unpaid and accrued interest shall be paid to Servier, and thereafter, all accrued and unpaid interest shall be due and payable at the end of each six-month period. In January 2014, the Company paid $1.9 million in accrued interest to Servier. The loan matures in 2016; however, after a specified period prior to final maturity, the loan is to be repaid (i) at Servier's option, by applying up to a significant percentage of any milestone or royalty payments owed by Servier under our collaboration agreement and (ii) using a significant percentage of any upfront, milestone or royalty payments we receive from any third-party collaboration or development partner for rights to gevokizumab in the U.S. and/or Japan. In addition, the loan becomes immediately due and payable upon certain customary events of default. At December 31, 2013, the outstanding principal balance under this loan was $20.6 million using the December 31, 2013 Euro to US Dollar exchange rate of 1.3766.

GECC Term Loan

In December 2011, we entered into a loan agreement (the “GECC Loan Agreement”) with GECC, under which GECC agreed to make a term loan in an aggregate principal amount of $10 million (the “Term Loan”) to us, and upon execution of the GECC Loan Agreement, GECC funded the Term Loan. As security for our obligations under the GECC Loan Agreement, we granted a security interest in substantially all of our existing and after-acquired assets, excluding our intellectual property assets (such as those relating to our gevokizumab and anti-botulism products). The Term Loan accrued interest at a fixed rate of 11.71% per annum and was to be repaid over a period of 42 consecutive equal monthly installments of principal and accrued interest and was due and payable in full on June 15, 2015. We incurred debt issuance costs of approximately $1.3 million in connection with the Term Loan and were required to pay a final payment fee equal to $500,000 on the maturity date, or such earlier date as the Term Loan is paid in full.

In connection with the GECC Loan Agreement, we issued to GECC unregistered warrants that entitle GECC to purchase up to an aggregate of 263,158 unregistered shares of XOMA common stock at an exercise price equal to $1.14 per share. These warrants are exercisable immediately and have a five-year term.

In September 2012, we entered into an amendment to the GECC Loan Agreement providing for an additional term loan in the amount of $4.6 million, increasing the term loan obligation to $12.5 million (the “Amended Term Loan”) and providing for an interest-only monthly repayment period following the effective date of the amendment through March 1, 2013, at a stated interest rate of 10.9% per annum. Thereafter, we are obligated to make monthly principal payments of $347,222, plus accrued interest, over a 27-month period commencing on April 1, 2013, and through June 15, 2015, at which time the remaining outstanding principal amount of $3.1 million, plus accrued interest, is due.  We incurred debt issuance costs of approximately $0.2 million and are required to make a final payment fee in the amount of $875,000 on the date upon which the outstanding principal amount is required to be repaid in full.  This final payment fee replaced the original final payment fee of $500,000.

In connection with the amendment, on September 27, 2012, we issued to GECC unregistered stock purchase warrants, which entitle GECC to purchase up to an aggregate of 39,346 shares of XOMA common stock at an exercise price equal to $3.54 per share. These warrants are exercisable immediately and have a five-year term.

At December 31, 2013, the outstanding principal balance under the Amended Term Loan was $9.4 million.

Proceeds received during the years 2013, 2012, and 2011 are being used to continue development of our gevokizumab product candidate and for other working capital and general corporate purposes.

*           *           *

We have incurred significant operating losses and negative cash flows from operations since our inception. At December 31, 2013, we had cash, cash equivalents, and short-term investments of $121.6 million. During 2014, we expect to continue using our cash, cash equivalents and short-term investments to fund ongoing operations. Additional licensing, antibody discovery and development collaboration agreements, government funding and financing arrangements may positively impact our cash balances. Based on our cash reserves and anticipated spending levels, anticipated cash inflows from collaborations, biodefense contracts and licensing transactions, funding availability included under our loan agreements, the proceeds from our equity offerings and other sources of funding that we believe to be available, we estimate that we have sufficient cash resources to meet our anticipated net cash needs into 2015. Any significant revenue shortfalls, increases in planned spending on development programs or more rapid progress of development programs than anticipated, as well as the unavailability of anticipated sources of funding, could shorten this period.  If adequate funds are not available, we will be required to delay, reduce the scope of, or eliminate one or more of our product development programs and further reduce personnel-related costs. Progress or setbacks by potentially competing products may also affect our ability to raise new funding on acceptable terms.

Commitments and Contingencies

Schedule of Contractual Obligations

Payments by period due under contractual obligations at December 31, 2013, are as follows (in thousands):

Contractual Obligations		Total				Less than 1 year				1 to 3 years				3 to 5 years				More than 5 years
Operating leases (1)		$	34,613			$	3,661			$	7,389			$	7,840			$	15,723
Debt Obligations (2)
Principal			44,818				5,917				38,901				-				-
Interest			5,380				3,037				2,343				-				-
Total		$	84,811			$	12,615			$	48,633			$	7,840			$	15,723

(1) Operating leases are net of sublease income of $0.1 million. See Note 11: Commitments and Contingencies to the accompanying consolidated financial statements for further discussion.

(2) See Item 7A: Quantitative and Qualitative Disclosures about Market Risk and Note 7: Long-Term Debt and Other Arrangements to the accompanying consolidated financial statements for further discussion of our debt obligation.

In addition to the above, we have committed to make potential future “milestone” payments to third parties as part of licensing and development programs. Payments under these agreements become due and payable only upon the achievement of certain developmental, regulatory and/or commercial milestones. Because it is uncertain if and when these milestones will be achieved, such contingencies, aggregating up to $76.6 million (assuming one product per contract meets all milestones) have not been recorded on our consolidated balance sheet. We are also obligated to pay royalties, ranging generally from 1% to 5% of the selling price of the licensed component and up to 40% of any sublicense fees to various universities and other research institutions based on future sales or licensing of products that incorporate certain products and technologies developed by those institutions. We are unable to determine precisely when and if our payment obligations under the agreements will become due as these obligations are based on future events, the achievement of which is subject to a significant number of risks and uncertainties.

Although operations are influenced by general economic conditions, we do not believe that inflation had a material impact on financial results for the periods presented. We believe that we are not dependent on materials or other resources that would be significantly impacted by inflation or changing economic conditions in the foreseeable future.

Recent Accounting Pronouncements

In February 2013, Accounting Standards Codification Topic 220, Comprehensive Income was amended to require companies to report, in one place, information about reclassifications out of accumulated other comprehensive income. Accordingly, a company can present this information on the face of the financial statements, if certain requirements are met, or the information must be presented in the notes to the financial statements. We adopted this guidance as of January 1, 2013, on a retrospective basis and the items reclassified out of accumulated other comprehensive income are not material for all periods presented.

Off Balance Sheet Arrangements

We do not have any off balance sheet arrangements, as defined in Item 303(a)(4)(ii) of Regulation S-K promulgated by the SEC.

Item 7A.

Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

Our exposure to market rate risk for changes in interest rates relates primarily to our investment portfolio and our loan facilities. By policy, we make our investments in high quality debt securities, limit the amount of credit exposure to any one non-U.S. Treasury issuer, and limit duration by restricting the term of the instrument. We generally hold investments to maturity, with a weighted average portfolio period of less than twelve months. However, if the need arose to liquidate such securities before maturity, we may experience losses on liquidation.

We hold interest-bearing instruments that are classified as cash, cash equivalents and short-term investments. Fluctuations in interest rates can affect the principal values and yields of fixed income investments. If interest rates in the general economy were to rise rapidly in a short period of time, our fixed income investments could lose value.

The following table presents the amounts and related weighted average interest rates of our cash, cash equivalents, and short-term investments at December 31, 2013 and 2012 (in thousands, except interest rate):

	Maturity		Carrying Amount (in thousands)				Fair Value (in thousands)				Weighted Average Interest Rate
December 31, 2013
Cash, cash equivalents, and short-term investments	Daily to 90 days		$	121,649			$	121,649				0.08	%
December 31, 2012
Cash, cash equivalents, and short-term investments	Daily to 90 days		$	85,332			$	85,332				0.06	%

As of December 31, 2013, we have an outstanding principal balance on our note with Novartis of $14.8 million, which is due in 2015. The interest rate on this note is charged at a rate of USD six-month LIBOR plus 2%, which was 2.35% at December 31, 2013. No further borrowing is available under this note.

As of December 31, 2013, we have an outstanding principal balance on our loan with Servier of €15.0 million, which converts to approximately $20.6 million at December 31, 2013. The interest rate on this loan is charged at a floating rate based on a Euro Inter-Bank Offered Rate (“EURIBOR”) and subject to a cap. The interest rate for the initial interest period was 3.22% and was reset semi-annually ranging from 2.33% to 3.83%. Interest for the six-month period from January 2014 through July 2014 was reset to 2.39%. No further borrowing is available under this loan.

As of December 31, 2013, we have an outstanding principal balance on our loan with GECC of $9.4 million, which is to be repaid with monthly principal payments of $347,222, plus accrued interest, over a 27-month period commencing on April 1, 2013, and through June 15, 2015, at which time the remaining outstanding principal amount of $3.1 million, plus accrued interest, is due. The loan accrues interest at a fixed rate of 10.90% per annum. No further borrowing is available under this loan.

The variable interest rate related to our long-term debt instruments is based on LIBOR for our Novartis note and EURIBOR for our Servier loan. We estimate that a hypothetical 100 basis point change in interest rates could increase or decrease our interest expense by approximately $0.4 million on an annualized basis. Our loan with GECC is not subject to interest rate risk as it accrues interest at a fixed rate.

Foreign Currency Risk

We hold debt, incur expenses, and may be owed milestones denominated in foreign currencies. The amount of debt owed, expenses incurred, or milestones owed to us will be impacted by fluctuations in these foreign currencies. When the U.S. Dollar weakens against foreign currencies, the U.S. Dollar value of the foreign-currency denominated debt, expense, and milestones increases, and when the U.S. Dollar strengthens against these currencies, the U.S. dollar value of the foreign-currency denominated debt, expense, and milestones decreases. Consequently, changes in exchange rates will affect the amount we are required to repay on our €15.0 million loan from Servier and may affect our results of operations. We estimate that a hypothetical 0.01 change the Euro to USD exchange rate could increase or decrease our unrealized gains or losses by approximately $0.2 million.

Our loan from Servier was fully funded in January 2011, with the proceeds converting to approximately $19.5 million using the January 13, 2011 Euro to U.S. dollar exchange rate of 1.3020.  At December 31, 2013, the €15.0 million outstanding principal balance under the Servier Loan Agreement would have equaled approximately $20.6 million using the December 31, 2013 Euro to USD exchange rate of 1.3766. In May 2011, in order to manage our foreign currency exposure relating to our principal and interest payments on our loan from Servier, we entered into two foreign exchange option contracts to buy €1.5 million and €15.0 million in January 2014 and January 2016, respectively. Upfront premiums paid on these foreign exchange option contracts totaled $1.5 million and they had an aggregate fair value of $0.4 million at December 31, 2013. Our use of derivative financial instruments represents risk management; we do not enter into derivative financial contracts for trading purposes.

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Vice President, Finance, Chief Financial Officer and Secretary, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this report. Our disclosure controls and procedures are intended to ensure that the information we are required to disclose in the reports that we file or submit under the Securities Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and (ii) accumulated and communicated to our management, including the Chief Executive Officer and Vice President, Finance, Chief Financial Officer and Secretary, as the principal executive and financial officers, respectively, to allow timely decisions regarding required disclosures. Based on this evaluation, our Chief Executive Officer and our Vice President, Finance, Chief Financial Officer and Secretary concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

There were no changes in our internal controls over financial reporting during 2013 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial accounting.

Management’s Report on Internal Control over Financial Reporting

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of XOMA Corporation:

We have audited XOMA Corporation’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 Framework) (the COSO criteria). XOMA Corporation’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, XOMA Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on   the COSO criteria .

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of XOMA Corporation as of December 31, 2013 and 2012 and the related consolidated statements of comprehensive loss, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2013, and our report dated March 12, 2014 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of XOMA Corporation:

We have audited the accompanying consolidated balance sheets of XOMA Corporation as of December 31, 2013 and 2012, and the related consolidated statements of comprehensive loss, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2013. These consolidated financial statements are the responsibility of XOMA Corporation’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of XOMA Corporation at December 31, 2013 and 2012, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), XOMA Corporation’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 Framework) and our report dated March 12, 2014 expressed an unqualified opinion thereon.

XOMA Corporation

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.	Description of Business

XOMA Corporation (“XOMA” or the “Company”), a Delaware corporation combines a portfolio of late-stage clinical programs and research activities to develop innovative therapeutic antibodies for which it intends to commercialize. XOMA focuses its scientific research on allosteric modulation, which offers opportunities for new classes of therapeutic antibodies to treat a wide range of human diseases. XOMA is developing its lead product candidate gevokizumab (IL-1 beta modulating antibody) with Les Laboratoires Servier (“Servier”) through a global Phase 3 clinical development program and ongoing proof-of-concept studies in other IL-1-mediated diseases. XOMA’s scientific research also has produced the XMet platform, which consists of three classes of preclinical antibodies, including selective insulin receptor modulators that could offer new approaches in the treatment of diabetes. The Company’s products are presently in various stages of development and most are subject to regulatory approval before they can be commercially launched.

2.	Basis of Presentation and Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures. On an on-going basis, management evaluates its estimates including, but not limited to, those related to contingent warrant liabilities, revenue recognition, research and development expense, long-lived assets, derivative instruments and stock-based compensation. The Company bases its estimates on historical experience and on various other market-specific and other relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ significantly from these estimates, such as the Company’s billing under government contracts. Under the Company’s contracts with the National Institute of Allergy and Infectious Diseases (“NIAID”), a part of the National Institutes of Health (“NIH”), the Company bills using NIH provisional rates and thus are subject to future audits at the discretion of NIAID’s contracting office. These audits can result in an adjustment to revenue previously reported.

Reclassifications

Certain reclassifications of prior period amounts have been made to the financial statements and accompanying notes to conform to the current period presentation. Prior period presentations of net product sales and royalty revenue have been reclassified into contract and other revenue because the net product sales and royalty revenue were not material for all periods presented. These reclassifications had no impact on the Company’s previously reported net loss or cash flows.

Newly Adopted Accounting Pronouncements

In February 2013, Accounting Standards Codification Topic 220, Comprehensive Income was amended to require companies to report, in one place, information about reclassifications out of accumulated other comprehensive income. Accordingly, a company can present this information on the face of the financial statements, if certain requirements are met, or the information must be presented in the notes to the financial statements. The Company adopted this guidance as of January 1, 2013, on a retrospective basis and the items reclassified out of accumulated other comprehensive income are not material for all periods presented.

Revenue Recognition

Revenue is recognized when the four basic criteria of revenue recognition are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably assured. The determination of criteria (2) is based on management’s judgments regarding whether a continuing performance obligation exists. The determination of criteria (3) and (4) are based on management’s judgments regarding the nature of the fee charged for products or services delivered and the collectability of those fees. Allowances are established for estimated uncollectible amounts, if any.

XOMA Corporation

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company recognizes revenue from its license and collaboration arrangements, contract services, product sales and royalties. Revenue arrangements with multiple elements are divided into separate units of accounting if certain criteria are met, including whether the delivered element has stand-alone value to the customer and whether there is objective and reliable evidence of the fair value of the undelivered items. The consideration received is allocated among the separate units based on their respective fair values and the applicable revenue recognition criteria are applied to each of the separate units. Advance payments received in excess of amounts earned are classified as deferred revenue until earned.

License and Collaborative Fees

Revenue from non-refundable license, technology access or other payments under license and collaborative agreements where the Company has a continuing obligation to perform is recognized as revenue over the expected period of the continuing performance obligation. The Company estimates the performance period at the inception of the arrangement and reevaluates it each reporting period. This reevaluation may shorten or lengthen the period over which the remaining revenue is recognized. Changes to these estimates are recorded on a prospective basis.

Milestone payments under collaborative and other arrangements are recognized as revenue upon completion of the milestone event, once confirmation is received from the third party and collectability is reasonably assured. This represents the culmination of the earnings process when the Company has no future performance obligations related to the payment. Milestone payments that are not substantive or that require a continuing performance obligation on the part of the Company are recognized over the expected period of the continuing performance obligation. Amounts received in advance are recorded as deferred revenue until the related milestone is completed.

Contract Revenue

Contract revenue for research and development involves the Company providing research and development and manufacturing services to collaborative partners, biodefense contractors or others. Revenue for certain contracts is accounted for by a proportional performance, or output-based, method where performance is based on estimated progress toward elements defined in the contract. The amount of contract revenue and related costs recognized in each accounting period are based on management’s estimates of the proportional performance during the period. Adjustments to estimates based on actual performance are recognized on a prospective basis and do not result in reversal of revenue should the estimate to complete be extended.

Up-front fees are recognized in the same manner as the final deliverable, which is generally ratably over the period of the continuing performance obligation. Given the uncertainties of research and development collaborations, significant judgment is required to determine the duration of the arrangement.

Net Product Sales

Revenue from net product sales are recorded in the periods these product sales are earned, in advance of collection. The product sale revenue and receivables in these instances is based upon communication with the distribution customers. Product sales are recorded net of allowances and accruals for prompt pay discounts, volume rebates, and product returns.

Royalty Revenue

Royalty revenue and royalty receivables are recorded in the periods these royalties are earned, in advance of collection. The royalty revenue and receivables in these instances is based upon communication with collaborative partners or licensees, historical information and forecasted sales trends.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Research and Development Expenses

The Company expenses research and development costs as incurred. Research and development expenses consist of direct costs such as salaries and related personnel costs, and material and supply costs, and research-related allocated overhead costs, such as facilities costs. In addition, research and development expenses include costs related to clinical trials. Expenses resulting from clinical trials are recorded when incurred based, in part on estimates as to the status of the various trials. From time to time, research and development expenses may include up-front fees and milestones paid to collaborative partners for the purchase of rights to in-process research and development. Such amounts are expensed as incurred.

Cash and Cash Equivalents and Short-term Investments

The Company considers all highly liquid debt instruments with maturities of three months or less at the time the Company acquires them to be cash equivalents.

Short-term investments include debt securities classified as available-for-sale. Available-for-sale securities are stated at fair value, with unrealized gains and losses, net of tax, if any, reported in other comprehensive income (loss). The estimate of fair value is based on publicly available market information. Realized gains and losses and declines in value judged to be other-than-temporary on available-for-sale securities are also included in investment and other income. The Company reviews its instruments for other-than-temporary impairment whenever the value of the instrument is less than the amortized cost. The cost of investments sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in investment and other income.

Property and Equipment and Long-Lived Assets

Property and equipment is stated at cost less depreciation. Equipment depreciation is calculated using the straight-line method over the estimated useful lives of the assets (three to seven years). Leasehold improvements, buildings and building improvements are depreciated using the straight-line method over the shorter of the lease terms or the useful lives (one to fifteen years).

The Company reviews the carrying values and depreciation lives of its long-lived assets whenever events or changes in circumstances indicate that the asset may not be recoverable. An impairment loss is recognized when the estimated future net cash flows expected to result from the use of an asset is less than its carrying amount. Long-lived assets include property and equipment and building and leasehold improvements. During 2012, the Company recorded accelerated depreciation of $1.3 million and an impairment loss of $0.8 million on long-lived assets in connection with the Company’s 2012 streamlining plan. See Note 5: Streamlining and Restructuring Charges for additional disclosure on the 2012 streamlining plan.

Warrants

The Company has issued warrants to purchase shares of its common stock in connection with financing activities. The Company accounts for some of these warrants as a liability at fair value and others as equity at fair value. The fair value of the outstanding warrants is estimated using the Black-Scholes Model. The Black-Scholes Model requires inputs such as the expected term of the warrants, expected volatility and risk-free interest rate. These inputs are subjective and require significant analysis and judgment to develop. For the estimate of the expected term, the Company uses the full remaining contractual term of the warrant. In 2013, the Company changed its expected volatility assumption in the Black-Scholes Model from a volatility implied from warrants issued by XOMA in recent private placement transactions to a volatility based on historical stock price volatility observed on XOMA’s underlying stock. A historical stock price volatility rate was determined to be a more precise indicator for the fair value calculation of the Company’s warrants due to time elapsed since these warrants were granted. The assumptions associated with contingent warrant liabilities are reviewed each reporting period and changes in the estimated fair value of these contingent warrant liabilities are recognized in other income (expense).

Income Taxes

The Company accounts for uncertain tax positions in accordance with Accounting Standards Codification Topic 740, Income Taxes ("ASC 740"). The application of income tax law and regulations are inherently complex.

ASC 740 provides for the recognition of deferred tax assets if realization of such assets is more likely than not.  Based upon the weight of available evidence, which includes the Company’s historical operating performance and carry-back potential, the Company has determined that total deferred tax assets should be fully offset by a valuation allowance.

Net Loss per Share of Common Stock

Basic net loss per share of common stock is based on the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share of common stock is based on the weighted average number of shares outstanding during the period, adjusted to include the assumed conversion of certain stock options, restricted stock units (“RSUs”), and warrants for common stock.

Potentially dilutive securities are excluded from the calculation of loss per share if their inclusion is anti-dilutive. The following table shows the total outstanding securities considered anti-dilutive and therefore excluded from the computation of diluted net loss per share (in thousands):

		December 31,
		2013				2012				2011
Options for common stock			7,087				5,603				3,890
Convertible preferred stock			-				-				67
Warrants for common stock			15,839				13,840				1,609
Total			22,926				19,443				5,566

For the years ended December 31, 2013, 2012, and 2011, all outstanding common stock equivalents were considered anti-dilutive and therefore the calculations of basic and diluted net loss per share are the same.

3.	Consolidated Financial Statement Detail

Cash and Cash Equivalents

At December 31, 2013, cash equivalents consisted of demand deposits of $18.9 million and money market funds of $82.8 million with maturities of less than 90 days at the date of purchase. At December 31, 2012, cash equivalents consisted of demand deposits of $7.8 million and money market funds of $37.5 million with maturities of less than 90 days at the date of purchase.

Short-term Investments

At December 31, 2013 and 2012, short-term investments consisted of U.S. treasury securities of $20.0 million and $40.0 million, respectively, with maturities of greater than 90 days and less than one year from the date of purchase.

Foreign Exchange Options

The Company holds debt and may incur revenue and expenses denominated in foreign currencies, which exposes it to market risk associated with foreign currency exchange rate fluctuations between the U.S. dollar and the Euro. The Company is required in the future to make principal and accrued interest payments in Euros on its €15.0 million loan from Servier (See Note 7: Long-Term Debt and Other Arrangements). In order to manage its foreign currency exposure related to these payments, in May 2011, the Company entered into two foreign exchange option contracts to buy €1.5 million and €15.0 million in January 2014 and January 2016, respectively. By having these option contracts in place, the Company’s foreign exchange rate risk is reduced if the U.S. dollar weakens against the Euro. However, if the U.S. dollar strengthens against the Euro, the Company is not required to exercise these options, but will not receive any refund on premiums paid.

Upfront premiums paid on these foreign exchange option contracts totaled $1.5 million. The fair values of these option contracts are revalued at each reporting period and are estimated based on pricing models using readily observable inputs from actively quoted markets. The fair values of these option contracts are included in other assets on the consolidated balance sheet and changes in fair value on these contracts are included in other income (expense) on the consolidated statements of comprehensive loss.

Contingent Warrant Liabilities

In March 2012, in connection with an underwritten offering, the Company issued five-year warrants to purchase 14,834,577 shares of XOMA’s common stock at an exercise price of $1.76 per share. These warrants contain provisions that are contingent on the occurrence of a change in control, which would conditionally obligate the Company to repurchase the warrants for cash in an amount equal to their fair value using the Black-Scholes Option Pricing Model (the “Black-Scholes Model”) on the date of such change in control. Due to these provisions, the Company is required to account for the warrants issued in March 2012 as a liability at fair value. In addition, the estimated liability related to the warrants is required to be revalued at each reporting period until the earlier of the exercise of the warrants, at which time the liability will be reclassified to stockholders' equity, or expiration of the warrants. At December 31, 2012, the fair value of the warrant liability was estimated to be $15.0 million using the Black-Scholes Model. The Company revalued the warrant liability at December 31, 2013 using the Black-Scholes Model and recorded the $59.9 million increase in the fair value as a loss in the revaluation of contingent warrant liabilities line of its consolidated statements of comprehensive loss. The Company also reclassified $6.2 million from contingent warrant liabilities to equity on its consolidated balance sheets due to the exercise of warrants. As of December 31, 2013, 12,562,682 of these warrants were outstanding and had a fair value of $68.7 million. This increase in liability is due primarily to the increase in the market price of the Company’s common stock at December 31, 2013 compared to December 31, 2012.

XOMA Corporation

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In February 2010, in connection with an underwritten offering, the Company issued five-year warrants to purchase 1,260,000 shares of XOMA’s common stock at an exercise price of $10.50 per share. In June 2009, the Company issued warrants to certain institutional investors as part of a registered direct offering. These warrants represent the right to acquire an aggregate of up to 347,826 shares of XOMA’s common stock over a five year period beginning December 11, 2009 at an exercise price of $19.50 per share. These warrants contain provisions that are contingent on the occurrence of a change in control, which would conditionally obligate the Company to repurchase the warrants for cash in an amount equal to their fair value using the Black-Scholes Model on the date of such change in control. Due to these provisions, the Company is required to account for the warrants issued in February 2010 and June 2009 as liabilities at fair value. At December 31, 2012, the fair value of the warrant liability was estimated to be $0.1 million using the Black-Scholes Model. The Company revalued the warrant liability at December 31, 2013 using the Black-Scholes Model and recorded the $1.1 million increase in the fair value as a loss in the revaluation of contingent warrant liabilities line of its consolidated statements of comprehensive loss. As of December 31, 2013, all of these warrants were outstanding and had an aggregate fair value of approximately $1.2 million.

In 2013, the Company deferred $1.5 million of revenue from contracts including Servier and NIH and recognized $4.9 million in revenue. In 2012, the Company deferred $5.9 million of revenue from contracts including Servier and NIH and recognized $9.4 million in revenue.

4.	Collaborative, Licensing and Other Arrangements

Collaborative and Other Agreements

Servier

In December 2010, the Company entered into a license and collaboration agreement with Servier, to jointly develop and commercialize gevokizumab in multiple indications, which provided for a non-refundable upfront payment of $15.0 million that was received by the Company in January 2011. The upfront payment was recognized over the eight month period that the initial group of deliverables were provided to Servier. In addition, the Company received a loan of €15.0 million, which was fully funded in January 2011, with the proceeds converting to $19.5 million at the date of funding. See Note 7: Long-Term Debt and Other Arrangements. Under the terms of the agreement, Servier has worldwide rights to cardiovascular disease and diabetes indications and rights outside the United States and Japan to all other indications, including NIU, Behçet’s uveitis and other inflammatory and oncology indications. XOMA retains development and commercialization rights in the United States and Japan for all indications other than cardiovascular disease and diabetes.  XOMA has an option to reacquire rights to cardiovascular disease and diabetes indications from Servier in the United States and Japan (the “Cardiometabolic Indications Option”).  If the Company exercises the Cardiometabolic Indications Option, we will be required to pay Servier an option fee and partially reimburse their incurred development expenses.  Each party has the right in certain circumstances to pursue development in indications not specified in the agreement, and in such event, the other party will have the option to participate in such development in certain circumstances, including reimbursement of a portion of the developing party’s expenses.

Under this agreement, Servier will fund all activities to advance the global clinical development and future commercialization of gevokizumab in cardiovascular-related diseases and diabetes.  Also, Servier funded the first $50 million of gevokizumab global clinical development and CMC expenses and continues to fund 50% of further expenses related to the NIU and Behçet’s uveitis indications. For the years ended December 31, 2013, 2012, and 2011, the Company recorded revenue of $13.6 million, $14.5 million, and $34.2 million, respectively, under this agreement, which included the revenue recognized in 2011 relating to the upfront payment.

The Company’s right to royalties with respect to a particular product and country will continue for so long as such product is sold in such country.

NIAID

In July 2006, the Company was awarded a $16.3 million contract to produce monoclonal antibodies for the treatment of botulism to protect United States citizens against the harmful effects of botulinum neurotoxins used in bioterrorism. The contract work was performed on a cost plus fixed fee basis. The original contract was for a three-year period, however the contract was extended into 2010. The Company recognizing revenue as the services are performed on a proportional performance basis. This work was complete in the third quarter of 2010. In 2011, the NIH conducted an audit of the Company’s actual data for period from January 1, 2007 through December 31, 2009 and developed final billing rates for this period. As a result, the Company retroactively applied these NIH rates to the invoices from this period resulting in an increase in revenue of $2.0 million from the NIH. Final rates were settled in the first quarter of 2012 through negotiations with the NIH. Upon settlement, the Company recognized the $2.0 million in revenue in 2012.

In September 2008, the Company announced that it had been awarded a $64.8 million multiple-year contract funded with federal funds from NIAID, a part of the NIH (Contract No. HHSN272200800028C), to continue development of anti-botulinum antibody product candidates. The contract work is being performed on a cost plus fixed fee basis over a three-year period. The Company is recognizing revenue under the arrangement as the services are performed on a proportional performance basis. In 2011, the NIH conducted an audit of the Company’s actual data for period from January 1, 2007 through December 31, 2009 and developed final billing rates for this period. As a result, the Company retroactively applied these NIH rates to the invoices from this period resulting in an increase in revenue of $1.1 million from the NIH, excluding $0.9 million billed to the NIH in 2010 resulting from the Company’s performance of a comparison of 2009 calculated costs incurred and costs billed to the government under provisional rates. Final rates will be settled through negotiations with the NIH. This revenue has been deferred and will be recognized upon completion of negotiations with and approval by the NIH. In 2013, the Company recognized revenue of $4.4 million under this contract, compared with $6.6 million in 2012 and $18.6 million in 2011.

In October 2011, the Company announced that NIAID had awarded the Company a new contract under Contract No. HHSN272201100031C for up to $28.0 million over 5 years to develop broad-spectrum antitoxins for the treatment of human botulism poisoning. The contract work is being performed on a cost plus fixed fee basis over the life of the contract and the Company is recognizing revenue under the arrangement as the services are performed on a proportional performance basis. In 2013, the Company recognized revenue of $4.7 million under this contract, compared with $2.5 million in 2012 and $0.1 million in 2011.

Servier – U.S. Perindopril Franchise

On January 17, 2012, the Company announced it had acquired certain U.S. rights to a portfolio of antihypertensive products from Servier. The portfolio includes ACEON® (perindopril erbumine), a currently marketed angiotensin converting enzyme (“ACE”) inhibitor, and three FDC product candidates where a form of proprietary perindopril (perindopril arginine) is combined with another active ingredient(s). The Company assumed commercialization activities for ACEON in January 2012.  In November 2012, the Company announced that the 837-patient Phase 3 trial for the FDC of perindopril arginine and amlodipine besylate (“FDC1”) met its primary endpoint.  Partial funding for the trial was provided by Servier. The Company expects to pay the balance of study expenses, consisting primarily of costs generated by its contract research organization, from the profits generated by its ACEON sales.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In connection with the original agreement, the Company paid a $1.5 million license fee to Servier in the third quarter of 2010. In July 2013, the Company transferred U.S. development and commercialization rights to the perindopril franchise to Symplmed Pharmaceuticals, LLC ("Symplmed"). Under the terms of the arrangement, XOMA received a minority equity position in Symplmed and up to double-digit royalties on sales of the first fixed-dose combination containing perindopril arginine and amlodipine besylate, if it is approved by the FDA. The Company recorded the minority equity position in the other assets line of its consolidated balance sheets. Symplmed, under a sublicense agreement, assumes U.S. marketing responsibilities for ACEON (perindopril erbumine), and XOMA continues to manage and be reimbursed for sales and distribution within its established commercial infrastructure until the ACEON New Drug Application (“NDA”) is transferred to Symplmed. The ACEON NDA was to be transferred on March 1, 2014, but Symplmed has requested an extension. Terms of an extension agreement, if any, are being negotiated. XOMA will continue to record gross ACEON sales in the contracts and other revenue line of its consolidated statements of comprehensive loss until the ACEON NDA is transferred. Following the ACEON NDA transfer, Symplmed will pay XOMA single-digit royalties on sales of ACEON.

Takeda

In November 2006, the Company entered into a fully funded collaboration agreement with Takeda for therapeutic monoclonal antibody discovery and development. Under the agreement, Takeda will make up-front, annual maintenance and milestone payments to the Company, fund its research and development and manufacturing activities for preclinical and early clinical studies and pay royalties on sales of products resulting from the collaboration. Takeda will be responsible for clinical trials and commercialization of drugs after an Investigational New Drug Application (“IND”) submission and is granted the right to manufacture once the product enters into Phase 2 clinical trials. During the collaboration, the Company will discover therapeutic antibodies against targets selected by Takeda. The Company will recognize revenue on the up-front and annual payments on a straight-line basis over the expected term of each target antibody discovery, on the research and development and manufacturing services as they are performed on a time and materials basis, on the milestones when they are achieved and on the royalties when the underlying sales occur. In 2013, the Company recognized revenue of $0.1 million under this agreement, compared with $1.2 million in 2012 and $2.0 million in 2011.

Under the terms of this agreement, the Company may receive milestone payments aggregating up to $19.0 million relating to one undisclosed product candidate and low single-digit royalties on future sales of all products subject to this license.  In addition, in the event Takeda were to develop additional future qualifying product candidates under the terms of the agreement, the Company would be eligible for milestone payments aggregating up to $20.75 million for each such qualifying product candidate.  The Company’s right to milestone payments expires on the later of the receipt of payment from Takeda of the last amount to be paid under the agreement or the cessation of all research and development activities with respect to all program antibodies, collaboration targets and/or collaboration products.  The Company’s right to royalties expires on the later of 13.5 years from the first commercial sale of each royalty-bearing discovery product or the expiration of the last-to-expire licensed patent.

In February 2009, the Company expanded its existing collaboration agreement with Takeda to provide Takeda with access to multiple antibody technologies, including a suite of research and development technologies and integrated information and data management systems. The Company may receive milestones of up to $3.25 million per discovery product candidate and low single-digit royalties on future sales of all antibody products subject to this license. The Company’s right to milestone payments expires on the later of the receipt of payment from Takeda of the last amount to be paid under the agreement or the cessation of all research and development activities with respect to all program antibodies, collaboration targets and/or collaboration products. The Company’s right to royalties expires on the later of 10 years from the first commercial sale of such royalty-bearing discovery product, or the expiration of the last-to-expire licensed patent.

Novartis

In November 2008, the Company restructured its product development collaboration with Novartis entered into in 2004 for the development and commercialization of antibody products for the treatment of cancer. Under the restructured agreement, the Company received $6.2 million in cash and $7.5 million in the form of debt reduction on its existing loan facility with Novartis. In addition, the Company may, in the future, receive potential milestones of up to $14.0 million and royalty rates ranging from low-double digit to high-teen percentage rates for two ongoing product programs, HCD122 and LFA 102 and options to develop or receive royalties on additional programs. In exchange, Novartis received control over the HCD122 and LFA 102 programs, as well as the right to expand the development of these programs into additional indications outside of oncology . The Company’s right to royalty-style payments expires on the later of the expiration of any licensed patent covering each product or 20 years from the launch of each product that is produced from a cell line provided to Novartis by XOMA. In 2013, the Company received a $7.0 million milestone relating to one currently active program. Pursuant to the obligations under the Agreement, in January 2014, the Company made a payment, equal to 25 percent of the milestone received, or $1.75 million, toward its outstanding debt obligation to Novartis.

XOMA Corporation

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A loan facility of up to $50 million was available to the Company to fund up to 75% of its share of development expenses incurred beginning in 2005. See Note 7: Long-Term Debt and Other Arrangements for additional disclosure of the financing arrangement between the Company and Novartis.

Licensing Agreements

XOMA has granted more than 60 licenses to biotechnology and pharmaceutical companies to use the Company’s patented and proprietary technologies relating to bacterial expression of recombinant pharmaceutical products. In exchange, the Company receives license and other fees as well as access to certain of these companies’ antibody display libraries, intellectual property and/or services that complement the Company’s existing development capabilities and support the Company’s own antibody product development pipeline.

Certain of these agreements also provide releases of the licensee companies and their collaborators from claims under the XOMA patents arising from past activities using the companies’ respective technologies to the extent they also used XOMA’s antibody expression technology. Licensees are often also allowed to use XOMA’s technology in combination with their own technology in future collaborations.

Pfizer

In August 2007, the Company entered into a license agreement with Pfizer Inc. (“Pfizer”) for non-exclusive, worldwide rights for XOMA’s patented bacterial cell expression technology for research, development and manufacturing of antibody products. Under the terms of the agreement, the Company received a license fee payment of $30 million in 2007.

From 2011 through 2013, the Company received milestone payments relating to ten undisclosed product candidates. The Company may also be eligible for additional milestone payments aggregating up to $15.2 million relating to twelve product candidates and low single-digit royalties on future sales of all products subject to this license. In addition, the Company may receive potential milestone payments aggregating up to $1.7 million for each additional qualifying product candidate. The Company’s right to milestone payments expires on the later of the expiration of the last-to-expire licensed patent or the tenth anniversary of the effective date. The Company’s right to royalties expires upon the expiration of the last-to-expire licensed patent.  The Company will recognize revenue on milestones when they are achieved and on royalties when the underlying sales occur.

5.	Streamlining and Restructuring Charges

In January 2012, the Company implemented a streamlining of operations, which resulted in a restructuring plan designed to sharpen its focus on value-creating opportunities led by gevokizumab and its unique antibody discovery and development capabilities. The restructuring plan included a reduction of XOMA’s personnel by 84 positions, or 34%. These staff reductions resulted primarily from the Company’s decisions to utilize a contract manufacturing organization for Phase 3 and commercial antibody production, and to eliminate internal research functions that are non-differentiating or that can be obtained cost effectively by contract service providers.

In connection with the streamlining of operations, the Company incurred restructuring charges in 2012 of $2.0 million related to severance, other termination benefits and outplacement services, $2.2 million related to the impairment and accelerated depreciation of various assets and leasehold improvements, and $0.7 million related to moving and other facility costs. In 2013, the Company incurred $0.3 million in restructuring charges related to facility costs and it does not expect to incur additional significant restructuring charges during 2014 related to these streamlining activities.

The current and long-term portions of the outstanding restructuring liabilities are included in accrued and other liabilities and other liabilities – long-term on the consolidated balance sheets and are based upon restructuring charges recognized as of December 31, 2013 and 2012 in connection with the Company’s restructuring plans. As of December 31, 2013 and 2012, the components of these liabilities are shown below (in thousands):

6.	Fair Value Measurements

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies ASC 820, which establishes a framework for measuring fair value and a fair value hierarchy that prioritizes the inputs used in valuation techniques. ASC 820 describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices in active markets for similar assets or liabilities.

Level 3 – Unobservable inputs.

The following tables set forth the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2013 and 2012 are classified as follows (in thousands):

Included in cash and cash equivalents

The fair value of the foreign exchange options at December 31, 2013 and 2012 was determined using readily observable market inputs from actively quoted markets obtained from various third-party data providers. These inputs, such as spot rate, forward rate and volatility have been derived from readily observable market data, meeting the criteria for Level 2 in the fair value hierarchy.

The fair value of the contingent warrant liabilities at December 31, 2013 and 2012 was determined using the Black-Scholes Model, which requires inputs such as the expected term of the warrants, volatility and risk-free interest rate. These inputs are subjective and generally require significant analysis and judgment to develop. In 2013, the Company changed its expected volatility assumption in the Black-Scholes Model from a volatility implied from warrants issued by XOMA in recent private placement transactions to a volatility based on historical stock price volatility observed on XOMA’s underlying stock. A historical stock price volatility rate was determined to be a more precise indicator for the fair value calculation of the Company’s warrants due to time elapsed since these warrants were granted.

The fair value of the contingent warrant liabilities was estimated using the following range of assumptions at December 31, 2013 and 2012:

		December 31, 2013				December 31, 2012
Expected volatility			66.1% - 86.6	%			40	%
Risk-free interest rate			0.1% - 0.8	%			0.3% - 0.7	%
Expected term		0.9 - 3.2 years				1.9 - 4.2 years

The following table provides a summary of changes in the fair value of the Company’s Level 3 financial liabilities for the years ended December 31, 2013, 2012 and 2011 (in thousands):

7.	Long-Term Debt and Other Arrangements

Novartis Note

In May 2005, the Company executed a secured note agreement with Novartis (then Chiron Corporation), which is due and payable in full in June 2015. Under the note agreement, the Company borrowed semi-annually to fund up to 75% of the Company’s research and development and commercialization costs under its collaboration arrangement with Novartis, not to exceed $50 million in aggregate principal amount. Interest on the principal amount of the loan accrues at six-month LIBOR plus 2%, which was equal to 2.35% at December 31, 2013, and is payable semi-annually in June and December of each year. Additionally, the interest rate resets in June and December of each year. At the Company’s election, the semi-annual interest payments can be added to the outstanding principal amount, in lieu of a cash payment, as long as the aggregate principal amount does not exceed $50 million. The Company has made this election for all interest payments thus far. Loans under the note agreement are secured by the Company’s interest in its collaboration with Novartis, including any payments owed to it thereunder.

At December 31, 2013 and 2012, the outstanding principal balance under this note agreement was $14.8 million and $14.4 million. Pursuant to the terms of the arrangement as restructured in November 2008, the Company will not make any additional borrowings under the Novartis note. Accrued interest of $0.4 million, $0.4 million and $0.3 million was added to the principal balance of the loan for the years ended December 31, 2013, 2012 and 2011, respectively.

Pursuant to the its obligations under the collaboration with Novartis, in January 2014, the Company made a payment, equal to 25 percent of a $7.0 million milestone received, or $1.75 million, toward its outstanding debt obligation to Novartis.

Servier Loan

In December 2010, in connection with the license and collaboration agreement entered into with Servier, the Company executed a loan agreement with Servier (the “Servier Loan Agreement”), which provided for an advance of up to €15.0 million. The loan was fully funded in January 2011, with the proceeds converting to approximately $19.5 million. The loan is secured by an interest in XOMA’s intellectual property rights to all gevokizumab indications worldwide, excluding certain rights in the U.S. and Japan. Interest is calculated at a floating rate based on a Euro Inter-Bank Offered Rate (“EURIBOR”) and subject to a cap. The interest rate is reset semi-annually in January and July of each year. The interest rate for the initial interest period was 3.22% and was reset semi-annually ranging from 2.33% to 3.83%. Interest for the six-month period from January 2014 through July 2014 was reset to 2.39%. Interest is payable semi-annually; however, the Servier Loan Agreement provides for a deferral of interest payments over a period specified in the agreement. During the deferral period, accrued interest will be added to the outstanding principal amount for the purpose of interest calculation for the next six-month interest period. On the repayment commencement date, all unpaid and accrued interest shall be paid to Servier and thereafter, all accrued and unpaid interest shall be due and payable at the end of each six-month period. In January 2014, the Company paid $1.9 million in accrued interest to Servier.

XOMA Corporation

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The loan matures in 2016; however, after a specified period prior to final maturity, the loan is to be repaid (i) at Servier's option, by applying up to a significant percentage of any milestone or royalty payments owed by Servier under the Company’s collaboration agreement and (ii) using a significant percentage of any upfront, milestone or royalty payments the Company receives from any third party collaboration or development partner for rights to gevokizumab in the U.S. and/or Japan.  In addition, the loan becomes immediately due and payable upon certain customary events of default. At December 31, 2013, the outstanding principal balance under this loan was $20.6 million using the 12/31/13 Exchange Rate of 1.3766. For the years ended December 31, 2013 and 2012, the Company recorded unrealized foreign exchange losses of $0.8 million and $0.4 million, respectively, and for the year ended December 31, 2011, the Company recorded an unrealized foreign exchange gain of $0.1 million, related to the re-measurement of the loan.

The loan has a stated interest rate lower than the market rate based on comparable loans held by similar companies, which represents additional value to the Company. The Company recorded this additional value as a discount to the face value of the loan amount, at its fair value of $8.9 million. The fair value of this discount, which was determined using a discounted cash flow model, represents the differential between the stated terms and rates of the loan, and market rates. Based on the association of the loan with the collaboration arrangement, the Company recorded the offset to this discount as deferred revenue.

 

The loan discount is amortized under the effective interest method over the expected five-year life of the loan. For the years ended December 31, 2013, 2012, and 2011, the Company recorded non-cash interest expense of $1.6 million, $1.4 million, and $1.4 million, respectively, resulting from the amortization of the loan discount. At December 31, 2013 and 2012, the net carrying value of the loan was $16.5 million and $14.2 million, respectively. For the years ended December 31, 2013 and 2012, the Company recorded unrealized foreign exchange gains of $0.2 million and $0.1 million, respectively, and for the year ended December 31, 2011, the Company recorded an unrealized foreign exchange loss of $0.6 million, related to the re-measurement of the loan discount.

The Company believes that realization of the benefit and the associated deferred revenue is contingent on the loan remaining outstanding over the five-year contractual term of the loan. If the Company were to stop providing service under the collaboration arrangement and the arrangement is terminated, the maturity date of the loan would be accelerated and a portion of measured benefit would not be realized. As the realization of the benefit is contingent, in part, on the provision of future services, the Company is recognizing the deferred revenue over the expected five-year life of the loan. The deferred revenue is amortized under the effective interest method, and for the years ended December 31, 2013, 2012, and 2011, the Company recorded $1.6 million, $1.4 million, and $1.4 million, respectively, of related non-cash revenue.

General Electric Capital Corporation Term Loan

In December 2011, the Company entered into a loan agreement (the “GECC Loan Agreement”) with General Electric Capital Corporation (“GECC”), under which GECC agreed to make a term loan in an aggregate principal amount of $10 million (the “Term Loan”) to the Company, and upon execution of the GECC Loan Agreement, GECC funded the Term Loan. As security for its obligations under the GECC Loan Agreement, the Company granted a security interest in substantially all of its existing and after-acquired assets, excluding its intellectual property assets (such as those relating to its gevokizumab and anti-botulism products). The Term Loan accrued interest at a fixed rate of 11.71% per annum and was to be repaid over a period of 42 consecutive equal monthly installments of principal and accrued interest and was due and payable in full on June 15, 2015. The Company incurred debt issuance costs of approximately $1.3 million in connection with the Term Loan and was required to pay a final payment fee equal to $500,000 on the maturity date, or such earlier date as the Term Loan is paid in full. The debt issuance costs and final payment fee were being amortized and accreted, respectively, to interest expense over the term of the Term Loan using the effective interest method.

In connection with the GECC Loan Agreement, the Company issued to GECC unregistered warrants that entitle GECC to purchase up to an aggregate of 263,158 unregistered shares of XOMA common stock at an exercise price equal to $1.14 per share. These warrants are exercisable immediately and have a five-year term. The Company allocated the aggregate proceeds of the GECC Term Loan between the warrants and the debt obligation based on their relative fair values.  The fair value of the warrants issued to GECC was determined using the Black-Scholes Model. The warrants’ fair value of $0.2 million was recorded as a discount to the debt obligation and was being amortized over the term of the loan using the effective interest method.

In September 2012, The Company entered into an amendment to the GECC Loan Agreement providing for an additional term loan in the amount of $4.6 million, increasing the term loan obligation to $12.5 million (the “Amended Term Loan”) and providing for an interest-only monthly repayment period following the effective date of the amendment through March 1, 2013, at a stated interest rate of 10.9% per annum. Thereafter, the Company is obligated to make monthly principal payments of $347,222, plus accrued interest, over a 27-month period commencing on April 1, 2013, and through June 15, 2015, at which time the remaining outstanding principal amount of $3.1 million, plus accrued interest, is due.  The Company incurred debt issuance costs of approximately $0.2 million and are required to make a final payment fee in the amount of $875,000 on the date upon which the outstanding principal amount is required to be repaid in full.  This final payment fee replaced the original final payment fee of $500,000. The debt issuance costs and final payment fee are being amortized and accreted, respectively, to interest expense over the term of the Amended Term Loan using the effective interest method.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In connection with the amendment, on September 27, 2012 the Company issued to GECC unregistered stock purchase warrants, which entitle GECC to purchase up to an aggregate of 39,346 shares of XOMA common stock at an exercise price equal to $3.54 per share. These warrants are exercisable immediately and have a five-year term. The warrants’ fair value of $0.1 million was recorded as a discount to the debt obligation and is being amortized over the term of the loan using the effective interest method. The warrants are classified in permanent equity on the consolidated balance sheets.

The Amended Term Loan does not change the remaining terms of the GECC Loan Agreement. The GECC Loan Agreement contains customary representations and warranties and customary affirmative and negative covenants, including restrictions on the ability to incur indebtedness, grant liens, make investments, dispose of assets, enter into transactions with affiliates and amend existing material agreements, in each case subject to various exceptions. In addition, the GECC Loan Agreement contains customary events of default that entitle GECC to cause any or all of the indebtedness under the GECC Loan Agreement to become immediately due and payable. The events of default include any event of default under a material agreement or certain other indebtedness.

The Company may prepay the Amended Term Loan voluntarily in full, but not in part, and any voluntary and certain mandatory prepayments are subject to a prepayment premium of 3% in the first year after the effective date of the loan amendment, 2% in the second year and 1% thereafter, with certain exceptions.  The Company will also be required to pay the $875,000 final payment fee in connection with any voluntary or mandatory prepayment. On the effective date of the loan amendment, the Company paid an accrued final payment fee in the amount of $0.2 million relating to the original final payment fee of $500,000.

At December 31, 2013 and 2012, the outstanding principal balance under the Amended Term Loan was $9.4 million and $12.5 million, respectively.

Aggregate future principal and final fee payments of the Company’s total interest bearing obligations - long-term as of December 31, 2013 are as follows (in thousands):

Federal income tax (benefit) provision		$	(14	)		$	(74	)		$	15
Total		$	(14	)		$	(74	)		$	15

The Company has significant losses in 2013, 2012 and 2011 and as such there was no material income tax expense for the years ended December 31, 2013, 2012 and 2011. The income tax benefits in 2013 primarily relates to federal refundable credit true-up from prior year.

The significant components of net deferred tax assets as of December 31, 2013 and 2012 were as follows (in millions):

		December 31,
		2013				2012
Capitalized research and development expenses		$	49.4			$	51.5
Net operating loss carryforwards			78.4				150.8
Research and development and other credit carryforwards			8.8				8.5
Other			23.5				23.3
Total deferred tax assets			160.1				234.1
Valuation allowance			(160.1	)			(234.1	)
Net deferred tax assets		$	-			$	-

The net (decrease) increase in the valuation allowance was $(74.0) million, $(6.0) million and $25.8 million for the years ended December 31, 2013, 2012 and 2011, respectively.

As of December 31, 2013, the Company had federal net operating loss carry-forwards of approximately $205.0 million and state net operating loss carry-forwards of approximately $164.0 million to offset future taxable income. The net operating loss carry-forwards include $2.1 million which relates to stock option deductions that will be recognized through additional paid in capital when utilized.  As such, these deductions are not reflected in the Company’s deferred tax assets.  No federal net operating loss carry-forward expired in 2013, 2012 and 2011. California net operating losses of $16.8 million, $10.4 million and $9.5 million expired in the years 2013, 2012 and 2011, respectively.

ASC 740 provides for the recognition of deferred tax assets if realization of such assets is more likely than not.  Based upon the weight of available evidence, which includes the Company’s historical operating performance and carry-back potential, the Company has determined that total deferred tax assets should be fully offset by a valuation allowance.

Based on an analysis under Section 382 of the Internal Revenue Code (which subjects the amount of pre-change NOLs and certain other pre-change tax attributes that can be utilized to an annual limitation), the Company experienced ownership changes in 2009 and 2012 which substantially limit the future use of its pre-change NOLs and certain other pre-change tax attributes per year.  The Company has excluded the NOLs and R&D credits that will expire as a result of the annual limitations in the deferred tax assets as of December 31, 2013. To the extent that the Company does not utilize its carry-forwards within the applicable statutory carry-forward periods, either because of Section 382 limitations or the lack of sufficient taxable income, the carry-forwards will expire unused.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company files income tax returns in the U.S. federal jurisdiction, State of California, and Ireland. The Internal Revenue Service has completed an audit of the Company's 2009 and 2010 federal income tax returns which resulted in no change. The Company’s federal income tax returns for tax years 2011 and beyond remain subject to examination by the Internal Revenue Service.  The Company’s California and Irish income tax returns for tax years 2009 and beyond remain subject to examination by the Franchise Tax Board and Irish Revenue Commissioner. In addition, all of the net operating losses and research and development credit carry-forwards that may be used in future years are still subject to adjustment.

The following table summarizes the Company's activity related to its unrecognized tax benefits (in thousands):

		December 31, 2013
Balance at January 1, 2013		$	4,104
Increase related to current year tax position			164
Increase related to prior year tax position			6
Balance at December 31, 2013		$	4,274

A total of $3.0 million of the unrecognized tax benefits would affect the Company's effective tax rate.  The Company currently has a full valuation allowance against its U.S. net deferred tax assets which would impact the timing of the effective tax rate benefit should any of these uncertain tax positions be favorably settled in the future.

The Company does not expect the unrecognized tax benefits to change significantly over the next twelve months. The Company will recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. As of December 31, 2013, the Company has not accrued interest or penalties related to uncertain tax positions.

9.	Compensation and Other Benefit Plans

The Company grants qualified and non-qualified stock options, restricted stock units (“RSUs”), common stock and other stock-based awards under various plans to directors, officers, employees and other individuals. Stock options are granted at exercise prices of not less than the fair market value of the Company’s common stock on the date of grant. Generally, stock options granted to employees fully vest four years from the grant date and expire ten years from the date of the grant or three months from the date of termination of employment (longer in case of death or certain retirements). However, certain options granted to employees vest monthly or immediately, certain options granted to directors vest monthly over one year or three years and certain options may fully vest upon a change of control of the Company or may accelerate based on performance-driven measures. Additionally, the Company has an Amended and Restated Employee Stock Purchase Plan (“ESPP”) that allows employees to purchase Company shares at a purchase price equal to 95% of the closing price on the exercise date.

Employee Stock Purchase Plan

Under the ESPP plan approved by the Company’s stockholders, the Company is authorized to issue up to 233,333 shares of common stock to employees through payroll deductions at a purchase price per share equal to 95% of the closing price of XOMA shares on the exercise date. An employee may elect to have payroll deductions made under the ESPP for the purchase of shares in an amount not to exceed 15% of the employee’s compensation.

In 2013, 2012, and 2011, employees purchased 15,262, 17,054, and 30,044 shares of common stock, respectively, under the ESPP. Net payroll deductions under the ESPP totaled $60,000, $46,000 and $54,000 for 2013, 2012, and 2011, respectively.

Deferred Savings Plan

Under section 401(k) of the Internal Revenue Code of 1986, the Board of Directors adopted, effective June 1, 1987, a tax-qualified deferred compensation plan for employees of the Company. Participants may make contributions which defer up to 50% of their eligible compensation per payroll period, up to a maximum for 2013 of $17,500 (or $23,000 for employees over 50 years of age). The Company may, at its sole discretion, make contributions each plan year, in cash or in shares of the Company’s common stock, in amounts which match up to 50% of the salary deferred by the participants. The expense related to these contributions was $0.9 million, $0.8 million and $1.1 million for the years ended December 31, 2013, 2012, and 2011, respectively, and 100% was paid in common stock in each year.

Stock Option Plans

Historically, option grants intended as long-term incentive compensation have been made pursuant to the Company’s 1981 Share Option Plan (the “Option Plan”) and Restricted Share Plan (the “Restricted Plan”). In May of 2010, the Compensation Committee and the full Board adopted, and in July of 2010 the Company’s stockholders approved, a new equity-based compensation plan, the 2010 Long Term Incentive and Share Award Plan, which has since been amended and restated as the Amended and Restated 2010 Long Term Incentive and Stock Award Plan (the “Long Term Incentive Plan”). The Long Term Incentive Plan is intended to consolidate the Company’s long-term incentive compensation under a single plan, by replacing the Option Plan, the Restricted Plan and the 1992 Directors Share Option Plan (the “Directors Plan”) going forward, and to provide a more current set of terms pursuant to which to provide this type of compensation.

The Long Term Incentive Plan grants stock options, RSUs, and other stock-based awards to eligible employees, consultants and directors. No further grants or awards will be made under the Option Plan, the Restricted Share Plan or the Directors Plan. Shares underlying options previously issued under the Option Plan, the Restricted Share Plan or the Directors Plan that are currently outstanding will, upon forfeiture, cancellation, surrender or other termination, become available under the Long Term Incentive Plan. Stock-based awards granted under the Long Term Incentive Plan may be exercised when vested and generally expire ten years from the date of the grant or three to six months from the date of termination of employment (longer in case of death or certain retirements). Vesting periods vary based on awards granted, however, certain stock-based awards may vest immediately or may accelerate based on performance-driven measures.

Up to 15,753,331 shares are authorized for issuance under the stock option plans. As of December 31, 2013, options and RSUs covering 9,184,913 shares of common stock were outstanding under the stock option plans.

Stock Options

In 2013, the Board of Directors of the Company approved grants under the Company’s Amended and Restated 2010 Long Term Incentive Plan for an aggregate of 1,168,203 stock options to certain employees and the directors of the Company. The stock options vest monthly over four years for employees and one year for directors.

In 2012, the Board of Directors of the Company approved grants under the Company’s Amended and Restated 2010 Long Term Incentive Plan for an aggregate of 2,351,445 stock options to certain employees and the directors of the Company. The stock options vest monthly over four years for employees and one year for directors.

In October 2011, the Board of Directors of the Company approved a grant under the Amended and Restated 2010 Long Term Incentive Plan for an aggregate of 1,097,926 stock options to certain employees of the Company. These stock options include immediate vesting in an amount equal to each employee's percentage of outstanding options that are exercisable immediately prior to this grant. The remaining portion will vest monthly over two years.

On August 31, 2011, the Company announced that Steven B. Engle resigned as Chairman of the Board, Chief Executive Officer and President of the Company. In the third quarter of 2011, the Company incurred a stock-based compensation charge of approximately $0.7 million, due to a modification to Mr. Engle’s stock options as a result of his resignation.

Stock-based Compensation Expense

The Company recognizes compensation expense for all stock-based payment awards made to the Company’s employees, consultants and directors based on estimated fair values. The valuation of stock option awards is determined at the date of grant using the Black-Scholes option pricing model. This model requires inputs such as the expected term of the option, expected volatility and risk-free interest rate. To establish an estimate of expected term, the Company considers the vesting period and contractual period of the award and its historical experience of stock option exercises, post-vesting cancellations and volatility. The estimate of expected volatility is based on the Company’s historical volatility. The risk-free rate is based on the yield available on United States Treasury zero-coupon issues. To establish an estimate of forfeiture rate, the Company considers its historical experience of option forfeitures and terminations.

The fair value of stock option awards was estimated using the Black-Scholes model with the following weighted average assumptions for the years ended December 31, 2013, 2012, and 2011:

		Year Ended December 31,
		2013				2012				2011
Dividend yield			0	%			0	%			0	%
Expected volatility			92	%			92	%			88	%
Risk-free interest rate			0.89	%			0.82	%			1.48	%
Expected term		5.6 years				5.6 years				5.4 years

The valuation of RSUs is determined at the date of grant using the closing stock price. The forfeiture rate impacts the amount of aggregate compensation for both stock options and RSUs. To establish an estimate of forfeiture rate, the Company used an independent third party to consider the Company’s historical experience of option forfeitures and terminations.

The following table shows total stock-based compensation expense included in the consolidated statements of comprehensive loss for the years ended December 31, 2013, 2012, and 2011 (in thousands):

		Year Ended December 31,
		2013				2012				2011
Research and development		$	2,358			$	2,391			$	3,672
Selling, general and administrative			2,741				1,893				4,087
Total stock-based compensation expense		$	5,099			$	4,284			$	7,759

There was no capitalized stock-based compensation cost as of December 31, 2013 or 2012, and there were no recognized tax benefits related to the Company’s stock-based compensation expense during the years ended December 31, 2013 or 2012.

10.	Capital Stock

Series B Preference Shares

In December 2003, the Company issued 2,959 Series B preference shares to Genentech, Inc. in repayment of $29.6 million of the outstanding balance under a convertible subordinated debt agreement. Pursuant to the rights of the Series B preference shares, the holder of Series B preference shares was not entitled to receive any dividends on the Series B preference shares. The Series B preference shares ranked senior with respect to rights on liquidation, winding-up and dissolution of the Company to all classes of common stock. Upon any voluntary or involuntary liquidation, dissolution or winding-up of the Company, the holder of Series B preference shares would have been entitled to receive $10,000 per Series B preference share (or $29.6 million in the aggregate) before any distribution was made on the common stock. The holder of the Series B preference shares had no voting rights, except as required under Bermuda law.

The holder of Series B preference shares had the right to convert Series B preference shares into shares of common stock at a conversion price equal to $116.25 per share, subject to adjustment in certain circumstances.

In April of 2011, the 2,959 Series B convertible preference shares were converted by Genentech into 254,560 shares of common stock. The $29.6 million liquidation preference associated with the Series B preference shares was eliminated as a result of this conversion.

In addition, the Company has committed to make potential future “milestone” payments to third parties as part of licensing and development programs. Payments under these agreements become due and payable only upon the achievement of certain developmental, regulatory and/or commercial milestones. Because it is uncertain if and when these milestones will be achieved, such contingencies, aggregating up to $76.6 million (assuming one product per contract meets all milestones events) have not been recorded on the consolidated balance sheet. The Company is unable to determine precisely when and if payment obligations under the agreements will become due as these obligations are based on milestone events, the achievement of which is subject to a significant number of risks and uncertainties.

Leases

As of December 31, 2013, the Company leased administrative, research facilities, and office equipment under operating leases expiring on various dates through April 2023. These leases require the Company to pay taxes, insurance, maintenance and minimum lease payments.

The Company estimates future minimum lease payments as of December 31, 2013 to be (in thousands):

		Operating Leases (a)
2014		$	3,661
2015			3,640
2016			3,749
2017			3,862
2018			3,978
Thereafter			15,723
Minimum lease payments		$	34,613

 

(a) Operating leases are net of future sublease income of $0.1 million.

Total rental expense, including other costs required under the Company’s leases, was approximately $3.5 million, $4.5 million and $5.1 million for the years ended December 31, 2013, 2012, and 2011, respectively. Rental expense based on leases allowing for escalated rent payments are recognized on a straight-line basis. The Company is required to restore certain of its leased property to certain conditions in place at the time of lease. The Company believes these costs will not be material to its operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In 2012, the Company vacated and subleased two of its leased facilities, which housed its large scale manufacturing operations and associated quality functions. The Company incurred $0.3 million in restructuring charges during 2013 in connection with a portion of lease payments not offset by sublease income for these buildings. The Company does not expect to incur any significant restructuring charges during 2014 in connection with these lease payments.

As a result of the restructuring in the second quarter of 2009, the Company vacated one of its leased buildings. Effective December 2010, the Company entered into a sublease agreement for this building through May of 2014. For the year ended December 31, 2013, the Company recognized $0.1 million in sublease income under this agreement. The Company will receive future sublease income of $0.1 million under this agreement.
