NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (unaudited)

Note 1 – Organization and Nature of Operations

Nephros, Inc. (“Nephros” or the “Company”) was incorporated under the laws of the State of Delaware on April 3, 1997. The Company was founded by health professionals, scientists and engineers affiliated with Columbia University to develop advanced end stage renal disease (“ESRD”) therapy technology and products.

Beginning in 2009, Nephros introduced high performance liquid purification filters to meet the demand for water purification in certain medical markets. The Company’s filters, generally classified as ultrafilters, are primarily used in hospitals for the prevention of infection from waterborne pathogens, such as legionella and pseudomonas, and in dialysis centers for the removal of biological contaminants from water and bicarbonate concentrate. The Company also develops and sells water filtration products for commercial applications, focusing on the hospitality and food service markets. The water filtration business is a reportable segment, referred to as the Water Filtration segment.

The Company’s pathogen detection systems are portable, near real-time systems designed to provide actionable data for infection control teams and other organizations. The pathogen detection system business is a reportable segment, referred to as the Pathogen Detection segment.

In July 2018, the Company formed a new subsidiary, Specialty Renal Products, Inc. (“SRP”), to drive the development of its second-generation hemodiafiltration system and other products focused on improving therapies for patients with renal disease. The Company transferred three patents to SRP, which were carried at zero book value. SRP is a reportable segment, referred to as the Renal Products segment.

The Company’s primary U.S. facilities are located at 380 Lackawanna Place, South Orange, New Jersey 07079, 3221 Polaris Avenue, Las Vegas, Nevada 89102 and 1015 Telegraph Street, Unit B, Reno, Nevada 89502.

In addition, the Company maintains small administrative offices in various locations in the United States and Ireland.

Note 2 – Basis of Presentation and Liquidity

Interim Financial Information

The accompanying unaudited condensed consolidated interim financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 and Article 10 of Regulation S-X. The condensed consolidated balance sheet as of December 31, 2019 was derived from the Company’s audited financial statements. Accordingly, these interim financial statements do not include all of the information and footnotes required by GAAP for annual financial statements. Results as of and for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020.

The condensed consolidated interim financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Reverse Stock Split

On May 22, 2019, the Company’s Board of Directors authorized a 1-for-9 reverse stock split and approved an amendment to the Company’s Certificate of Incorporation to affect the 1-for-9 reverse split of the Company’s common stock, which was effected at 5:30 p.m. ET on July 9, 2019. Fractional shares were not issued and stockholders who otherwise would have been entitled to receive a fractional share as a result of the reverse stock split received an amount in cash equal to $5.58 per share for such fractional interests. All of the share and per share amounts discussed in the accompanying condensed consolidated financial statements have been adjusted to reflect the effect of this reverse split.

Consolidation

The accompanying condensed consolidated financial statements include the accounts of Nephros, Inc. and its subsidiaries, including SRP, in which a controlling interest is maintained by the Company. Outside shareholders’ interest in SRP of 37.5% is shown on the condensed consolidated balance sheet as noncontrolling interest. All intercompany accounts and transactions were eliminated in the preparation of the accompanying condensed consolidated financial statements.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amount of revenues and expenses, during the reporting period. Actual results could differ materially from those estimates. Included in these estimates are assumptions about the collection of accounts receivable, value of inventories, useful life of fixed assets and intangible assets, the assessment of expected cash flows used in evaluating goodwill and other long-lived assets, value of contingent consideration, the assessment of the ability to continue as a going concern and assumptions used in determining stock compensation such as expected volatility and risk-free interest rate.

Liquidity

The Company has sustained operating losses and expects such losses to continue over the next several quarters. In addition, net cash from operations has been negative since inception, generating an accumulated deficit of $130.1 million as of June 30, 2020.

On February 4, 2020, the Company completed a confidentially marketed underwritten public offering whereby the Company sold 937,500 shares of its common stock for aggregate net proceeds of $6.8 million. Additionally, the Company received $0.5 million from the U.S. Small Business Administration’s Paycheck Protection Program (“PPP”) on April 24, 2020. The PPP was established by the Coronavirus Aid, Relief and Economic Security Act (CARES Act), enacted on March 27, 2020, in response to the Coronavirus Disease 2019 (COVID-19) pandemic. Under the terms of the PPP, certain amounts of the loan may be forgiven if they are used for qualifying expenses during the first 24 weeks of the loan. The Company intends to use the entire amount for such qualifying expenses.

On May 26, 2020, the Company terminated its loan agreement with a lender, which had provided a secured asset-based revolving credit facility of up to $2.5 million. As of June 30, 2020, there was no outstanding amount due under the secured asset-based revolving facility.

On September 5, 2018, SRP completed a private placement transaction whereby SRP sold preferred shares equivalent to 37.5% of its outstanding equity interests for aggregate proceeds of $3.0 million. As of the date of issuance of the accompanying condensed consolidated financial statements, SRP had utilized the proceeds from this private placement. Nephros intends to loan operating funds to SRP at least through the planned FDA 510(k) clearance process of SRP’s second-generation hemodiafiltration system, which is expected to be complete before the end of 2020.

Based on cash that is available for the Company’s operations and projections of future Company operations, the Company believes that its cash balances will be sufficient to fund its current operating plan – including the potential negative impact of the COVID-19 pandemic – through at least the next 12 months from the date of issuance of the accompanying condensed consolidated financial statements. Additionally, the Company’s operating plans are designed to help control operating costs and to increase revenue until such time as the Company generates sufficient cash flows from operations. However, there is uncertainty with respect to the Company’s projections regarding the availability of sufficient cash resources as a result of the COVID-19 crisis and the economic conditions it has caused. In recent months, the Company has seen decreased demand for its products both with respect to new hospital customers and its existing hospital, restaurant and hospitality customers, which have been significantly impacted by the COVID-19 crisis. If this decrease in demand continues beyond the third quarter of 2020 and the Company is unable to achieve its revenue plan, the Company may be forced to cut costs as appropriate to preserve its available capital resources. If the Company is unable to sufficiently decrease its spending to match any future decreased demands for its products, the Company may exhaust its capital resources sooner than it currently anticipates. Further, as a result of the recent volatility of the capital markets and economic conditions generally, it may be difficult for the Company to raise additional capital at times when it may need it, and even if the Company were able to raise additional capital, it may be on terms than are detrimental to the Company. Accordingly, the current economic conditions caused by the COVID-19 crisis place uncertainty on the Company’s ability to maintain adequate levels of liquidity.

As of June 30, 2020 and December 31, 2019, the following customers, all of which are in the Water Filtration segment, accounted for the following percentages of the Company’s accounts receivable, respectively:

Cash and Cash Equivalents

The Company considers all highly liquid money market instruments with an original maturity of three months or less when purchased to be cash equivalents. At June 30, 2020 and December 31, 2019, cash and cash equivalents were deposited in financial institutions and consisted entirely of immediately available fund balances. The Company maintains its cash deposits and cash equivalents with financial institutions it believes to be well-known and stable.

Accounts Receivable

The Company provides credit terms to customers in connection with purchases of the Company’s products. Management periodically reviews customer account activity in order to assess the adequacy of the allowances provided for potential collection issues and returns. Factors considered include economic conditions, each customer’s payment and return history and credit worthiness. Adjustments, if any, are made to reserve balances following the completion of these reviews to reflect management’s best estimate of potential losses. There was no allowance for doubtful accounts as of June 30, 2020. The allowance for doubtful accounts was approximately $25,000 as of December 31, 2019. For the three and six months ended June 30, 2020 and 2019, there was no provision for bad debt expense. Write-offs of accounts receivable were approximately $25,000 for the three and six months ended June 30, 2020 which were reserved for in a prior period. Write-offs of accounts receivable were approximately $1,000 and $5,000, respectively, for the three and six months ended June 30, 2019 which were reserved for in a prior period. There was no allowance for sales returns at June 30, 2020 or December 31, 2019.

Note 3 – Revenue Recognition

The Company recognizes revenue related to product sales when product is shipped via external logistics provider and the other criteria of ASC 606, “Revenue from Contracts with Customers” (“ASC 606”) are met. Product revenue is recorded net of returns and allowances. In addition to product revenue, the Company recognizes revenue related to royalty and other agreements in accordance with the five-step model in ASC 606. Royalty and other revenue recognized for the three and six months ended June 30, 2020 and 2019 is comprised of:

Bellco License Agreement

With regard to the OLpūr MD190 and MD220, on June 27, 2011, the Company entered into a License Agreement (the “License Agreement”), effective July 1, 2011, with Bellco S.r.l. (“Bellco”), an Italy-based supplier of hemodialysis and intensive care products, for the manufacturing, marketing and sale of the Company’s patented mid-dilution dialysis filters (the “Products”). Under the License Agreement, as amended, the Company granted Bellco a license to manufacture, market and sell the Products under its own name, label, and CE mark in certain countries on an exclusive basis, and to do the same on a non-exclusive basis in certain other countries. Under the License Agreement with Bellco, the Company received upfront payments which were previously deferred and subsequently recognized as license revenue over the term of the License Agreement.

The License Agreement, as amended, also provides minimum sales targets which, if not satisfied, will, at the discretion of the Company, result in conversion of the license to non-exclusive status. Beginning on January 1, 2015 through and including December 31, 2021, Bellco will pay the Company a royalty based on the number of units of Products sold per year in the covered territory as follows: for the first 125,000 units sold in total, €1.75 (approximately $1.90) per unit; thereafter, €1.25 (approximately $1.40) per unit. The License Agreement also provides for a fixed royalty payment payable to the Company for the period beginning on January 1, 2015 through and including December 31, 2021 if the minimum sales targets are not met.

The Company recognized royalty income from Bellco pursuant to the License Agreement of approximately $13,000 and $14,000 for the three months ended June 30, 2020 and 2019, respectively. The Company recognized royalty income from Bellco pursuant to the License Agreement of approximately $29,000 and $40,000 for the six months ended June 30, 2020 and 2019, respectively.

Note 4 – Fair Value Measurements

The Company measures certain financial instruments and other items at fair value.

To determine the fair value, the Company uses the fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs based on assumptions about the factors market participants would use to value an asset or liability.

To measure fair value, the Company uses the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable:

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

Level 2 – Inputs other than Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Value is determined using pricing models, discounted cash flow methodologies, or similar techniques and also includes instruments for which the determination of fair value requires significant judgment or estimation.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level of classification for each reporting period.

The following table sets forth the Company’s financial assets and liabilities that were measured at fair value on a recurring basis as of June 30, 2020:

The following table sets forth the Company’s financial assets and liabilities that were measured at fair value on a recurring basis as of December 31, 2019:

The following table summarizes the change in fair value, as determined by Level 3 inputs, for the contingent consideration liability using unobservable Level 3 inputs for the six months ended June 30, 2020:

During the three months ended June 30, 2020, contingent consideration payments were extended through March 31, 2021, with the provision that no payment would be made for the three-month period ended June 30, 2020. As a result, no change in fair value of contingent consideration was recorded during the three months ended June 30, 2020.

During the six months ended June 30, 2020 and 2019, a change in fair value of contingent consideration of approximately $42,000 and $19,000, respectively, was recorded due to lower than planned performance. During the three months ended June 30, 2019, a change in fair value of contingent consideration of approximately $9,000 was recorded due to lower than planned performance.

Consideration paid in a business combination may include potential future payments that are contingent upon the acquired business achieving certain levels of earnings in the future (“contingent consideration”). Contingent consideration liabilities are measured at their estimated fair value as of the date of acquisition, with subsequent changes in fair value recorded in the consolidated statements of operations. Fair value as of the date of acquisition is estimated based on projections of expected future cash flows of the acquired business. The Company estimated the contingent consideration liability using the income approach (discounted cash flow method), which requires the Company to make estimates and assumptions regarding the future cash flows and profits. Changes in these estimates and assumptions could have a significant impact on the amounts recognized.

There were no transfers between levels in the fair value hierarchy during the three and six months ended June 30, 2020.

Assets and Liabilities Not Measured at Fair Value on a Recurring Basis

The carrying amounts of cash and cash equivalents, accounts receivable, secured revolving credit facility, accounts payable and accrued expenses approximate fair value due to the short-term maturity of these instruments.

The carrying amounts of the secured long-term note payable, lease liabilities and equipment financing approximate fair value as of June 30, 2020 and December 31, 2019 because those financial instruments bear interest at rates that approximate current market rates for similar agreements with similar maturities and credit.

The carrying amount of the PPP loan does not include interest imputed at a market rate as the PPP loan is a transaction whereby the interest rate is prescribed by a government agency.

Note 5 – Inventory, net

Inventory is stated at the lower of cost or net realizable value using the first-in, first-out method and consists of raw materials and finished goods. The Company’s inventory components as of June 30, 2020 and December 31, 2019 were as follows:

The Company recognized amortization expense of approximately $11,000 for each of the three months ended June 30, 2020 and 2019 and such amounts are included in selling, general and administrative expenses on the accompanying condensed consolidated statement of operations and comprehensive loss. The Company recognized amortization expense of approximately $21,000 for each of the six months ended June 30, 2020 and 2019 and such amounts are included in selling, general and administrative expenses on the accompanying condensed consolidated statement of operations and comprehensive loss.

As of June 30, 2020, future amortization expense for each of the next five years is (in thousands):

The Company did not recognize any intangible asset impairment charges during the three and six months ended June 30, 2020 or 2019.

Goodwill

Goodwill had a carrying value on the Company’s condensed consolidated balance sheets of $0.8 million at June 30, 2020 and December 31, 2019. Goodwill has been allocated to the Water Filtration segment.

Note 7 – License and Supply Agreement, net

On April 23, 2012, the Company entered into a License and Supply Agreement (the “License and Supply Agreement”) with Medica S.p.A. (“Medica”), an Italy-based medical product manufacturing company, for the marketing and sale of certain filtration products based upon Medica’s proprietary Medisulfone ultrafiltration technology in conjunction with the Company’s filtration products, and for an exclusive supply arrangement for the filtration products. Under the License and Supply Agreement, as amended, Medica granted to the Company an exclusive license, with right of sublicense, to market, promote, distribute, offer for sale and sell the filtration products worldwide, with certain limitations on territory, during the term of the License and Supply Agreement. In addition, the Company granted to Medica an exclusive license under the Company’s intellectual property to make the filtration products during the term of the License and Supply Agreement. The filtration products covered under the License and Supply Agreement includes both certain products based on Medica’s proprietary Versatile microfiber technology and certain filtration products based on Medica’s proprietary Medisulfone ultrafiltration technology. The term of the License Agreement with Medica expires on December 31, 2025, unless earlier terminated by either party in accordance with the terms of the License and Supply Agreement.

In exchange for the license, the gross value of the intangible asset capitalized was $2.3 million. License and supply agreement, net on the condensed consolidated balance sheet is $0.7 million and $0.8 million as of June 30, 2020 and December 31, 2019, respectively. Accumulated amortization is $1.6 million and $1.5 million as of June 30, 2020 and December 31, 2019, respectively. The intangible asset is being amortized as an expense over the life of the License and Supply Agreement. Amortization expense of approximately $33,000 was recognized in each of the three months ended June 30, 2020 and 2019 on the condensed consolidated statement of operations and comprehensive loss. Amortization expense of approximately $67,000 was recognized in each of the six months ended June 30, 2020 and 2019 on the condensed consolidated statement of operations and comprehensive loss.

As of September 2013, the Company has an understanding with Medica whereby the Company has agreed to pay interest to Medica at a 12% annual rate calculated on the principal amount of any outstanding invoices that are not paid pursuant to the original payment terms. There was no interest recognized for the three or six months ended June 30, 2020 or 2019.

In addition, for the period beginning April 23, 2014 through December 31, 2025, the Company will pay Medica a royalty rate of 3% of net sales of the filtration products sold, subject to reduction as a result of a supply interruption pursuant to the terms of the License and Supply Agreement. Approximately $44,000 and $61,000 for the three months ended June 30, 2020 and 2019, respectively, was recognized as royalty expense and is included in cost of goods sold on the condensed consolidated statement of operations and comprehensive loss. Approximately $113,000 and $108,000 for the six months ended June 30, 2020 and 2019, respectively, was recognized as royalty expense and is included in cost of goods sold on the condensed consolidated statement of operations and comprehensive loss. Approximately $44,000 in royalties are included in accrued expenses as of June 30, 2020. Approximately $83,000 in royalties are included in accounts payable as of December 31, 2019.

Note 8 – Secured Revolving Credit Facility

On August 17, 2017, the Company entered into the Loan Agreement and Security Agreement (the “Loan Agreement”) with Tech Capital, LLC (“Tech Capital”). The Loan Agreement initially provided for a secured asset-based revolving credit facility (the “Revolver”) of up to $1.0 million, which the Company drew upon and repaid from time to time during the term of the Loan Agreement. On December 20, 2019, the Company and Tech Capital entered into a First Modification to the Loan Agreement (“the Amendment”). The Amendment increased the Revolver from $1.0 million to $2.5 million. The outstanding principal balance of the Loan Agreement was $0.6 million as of December 31, 2019. The Company used these proceeds for working capital and general corporate purposes.

On May 26, 2020, the Company terminated the Revolver and, as a result, recognized fees of approximately $7,000, which are included interest expense on the condensed consolidated statement of operations and comprehensive loss for the three and six months ended June 30, 2020. Although the Revolver was terminated, the Loan Agreement remains in place for purposes of specifying obligations related to the Secured Note Payable (Note 9 – Secured Note Payable).

For the three and six months ended June 30, 2020, excluding approximately $7,000 related to the termination of the Revolver, approximately $6,000 and $25,000, respectively, was recognized as interest expense on the condensed consolidated statement of operations and comprehensive loss.

The Secured Note has a maturity date of April 1, 2023. The unpaid principal balance accrues interest at a rate of 8% per annum. Principal and interest payments are due on the first day of each month commencing on May 1, 2018.

The Secured Note is subject to the terms and conditions of and is secured by security interests granted by the Company in favor of Tech Capital under the Loan Agreement and all of the riders and amendments thereto (see Note 8 – Secured Revolving Credit Facility). The Secured Note was amended and restated on May 26, 2020. There were no changes to the terms and conditions of the Secured Note. An event of default under such Loan Agreement is an event of default under the Secured Note and vice versa. In the event the principal balance under the Loan Agreement is due, all amounts due under the Secured Note also become due.

The Loan Agreement, as amended on May 26, 2020, also granted to Tech Capital a first priority security interest in its assets, including its accounts receivable and inventory, to secure all of its obligations under the Secured Note. In addition, Nephros International Limited, a wholly-owned subsidiary of the Company, unconditionally guaranteed the Company’s obligations under the Loan Agreement.

Note 13 – Stockholders’ Equity

February 2020 Common Stock Issuance

On February 4, 2020, the Company issued 937,500 shares of common stock through a confidentially marketed underwritten public offering resulting in gross proceeds to the Company of $7.5 million. The purchase price for each share was $8.00. Proceeds, net of equity issuance costs of $0.7 million, recorded as a result of the offering were $6.8 million.

Noncontrolling Interest

On September 5, 2018, SRP entered into a Series A Preferred Stock Purchase Agreement with certain purchasers pursuant to which SRP sold 600,000 shares of its Series A Preferred Stock (“Series A Preferred”) for $5.00 per share. The aggregate purchase price was $3.0 million. SRP incurred transaction-related expenses of approximately $30,000, which were included in selling, general and administrative expenses on the accompanying consolidated statement of operations and comprehensive loss for the three and nine months ended September 30, 2018. The net proceeds from the issuance of the Series A Preferred are restricted to SRP expenses, and may not be used for the benefit of the Company or other affiliated entities, except to reimburse for expenses directly attributable to SRP. Following the Series A Preferred transaction, the Company retained a 62.5% ownership interest in SRP, holding 100% of the outstanding common shares, and holders of Series A Preferred retained a 37.5% interest in SRP on a fully diluted basis, holding 100% of the outstanding preferred shares. Of the 600,000 shares of Series A Preferred issued, the shares purchased by related parties comprised of persons controlled by members of management and by the Company’s largest shareholder amounted to 18,000 and 400,000 shares, respectively.

Each share of Series A Preferred is initially convertible into one share of SRP common stock, subject to adjustment for stock splits and recapitalization events. Subject to customary exempt issuances, in the event SRP issues additional shares of its common stock or securities convertible into common stock at a per share price that is less than the original Series A Preferred price, the conversion price of the Series A Preferred will automatically be reduced to such lower price.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of SRP, the holders of the Series A Preferred are entitled to be paid out of the assets of SRP available for distribution to its stockholders or, in the case of a deemed liquidation event, out of the consideration payable to stockholders in such deemed liquidation event or the available proceeds, before any payment shall be made to the holders of SRP common stock by reason of their ownership thereof, an amount per share equal to one times (1x) the Series A Preferred original issue price, plus any accruing dividends accrued but unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon (the “Series A Liquidation Preference”). If upon any such liquidation, dissolution or winding up of SRP or deemed liquidation event, the assets of SRP available for distribution to its stockholders shall be insufficient to pay the Series A Liquidation Preference in full, the holders of Series A Preferred shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. After the full payment of the Series A Liquidation Preference, the holders of the Series A Preferred and the holders of common stock will share ratably in any remaining proceeds available for distribution on an as-converted to common stock basis.

Each share of Series A Preferred accrues dividends at the rate per annum of $0.40 per share. The accruing dividends shall accrue from day to day, whether or not declared, and shall be cumulative and shall be payable only when, as, and if declared by the Board.

Holders of Series A Preferred shall be entitled to cast the number of votes equal to the number of whole shares of common stock into which the shares of Series A Preferred held by such holder are convertible as of the record date for determining stockholders entitled to vote. Except as provided by law or by the other provisions, the holders of Series A Preferred vote together with the holders of common stock as a single class. Notwithstanding the foregoing, for as long as at least 150,000 shares of Series A Preferred are outstanding, SRP is required to obtain the affirmative vote or written consent of a majority of the Series A Preferred in order to effect certain corporate transactions, including without limitation, the issuance of any securities senior to or on parity with the Series A Preferred, a liquidation or deemed liquidation of SRP, amendments to SRP’s charter documents, the issuance of indebtedness in excess of $250,000, any annual budget for the Company’s operations, and the hiring or firing of any executive officers of SRP. In addition, the holders of the Series A Preferred are entitled to elect two members of SRP’s board of directors.

The noncontrolling interest in SRP held by holders of the Series A Preferred has been classified as equity on the accompanying consolidated interim balance sheet, as the noncontrolling interest is redeemable only upon the occurrence of events that are within the control of the Company.

There were no warrants issued during the three or six months ended June 30, 2020 or 2019.

Note 14 – Net Loss per Common Share

Basic loss per common share is calculated by dividing net loss available to common shareholders by the number of weighted average common shares issued and outstanding. Diluted loss per common share is calculated by dividing net loss available to common shareholders by the weighted average number of common shares issued and outstanding for the period, plus amounts representing the dilutive effect from the exercise of stock options and warrants, as applicable. The Company calculates dilutive potential common shares using the treasury stock method, which assumes the Company will use the proceeds from the exercise of stock options and warrants to repurchase shares of common stock to hold in its treasury stock reserves.

The following potentially dilutive securities have been excluded from the computations of diluted weighted average shares outstanding as they would be antidilutive:

Note 15 – Commitments and Contingencies

Note 16 – Segment Reporting

On January 1, 2020, the Company began reporting the results of its Pathogen Detection Systems business as a new segment, known as the Pathogen Detection segment. Prior to the additional reporting of Pathogen Detection as a reporting segment, the Company had two operating segments, Water Filtration and Renal Products. The Company reflected the new segment measures beginning in the three months ended March 31, 2020, and prior periods have been restated for comparability.

The Company has defined three reportable segments: Water Filtration, Pathogen Detection and Renal Products. The Water Filtration segment primarily develops and sells high performance water purification filters. The Pathogen Detection segment develops and sells portable, real-time water testing systems designed to provide actionable data on waterborne pathogens in approximately one hour. The Renal Products segment is focused on the development of medical device products for patients with renal disease, including a 2^nd generation hemodiafiltration system for the treatment of patients with ESRD.

The Company’s chief operating decision maker evaluates the financial performance of the Company’s segments based upon segment revenues, gross margin and operating expenses which include research and development and selling, general and administrative expenses. Items below loss from operations are not reported by segment, since they are excluded from the measure of segment profitability reviewed by the Company’s chief operating decision maker. The Company does not report balance sheet information by segment since it is not reviewed by the Company’s chief operating decision maker.

The accounting policies for the Company’s segments are the same as those described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

The tables below present segment information reconciled to total Company loss from operations, with segment operating loss including gross profit less direct research and development expenses and direct selling, general and administrative expenses to the extent specifically identified by segment:
