NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.  BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

The unaudited condensed consolidated financial statements of Community Health Systems, Inc. and its subsidiaries (the “Company”) as of June 30, 2013 and December 31, 2012 and for the three-month and six-month periods ended June 30, 2013 and June 30, 2012, have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the opinion of management, such information contains all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for such periods. All intercompany transactions and balances have been eliminated. The results of operations for the three and six months ended June 30, 2013, are not necessarily indicative of the results to be expected for the full fiscal year ending December 31, 2013. Certain information and disclosures normally included in the notes to consolidated financial statements have been condensed or omitted as permitted by the rules and regulations of the Securities and Exchange Commission (the “SEC”). The Company believes the disclosures are adequate to make the information presented not misleading. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2012, contained in the Company’s Annual Report on Form 10-K.

Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the parent are presented as a component of total equity on the condensed consolidated balance sheets to distinguish between the interests of the parent company and the interests of the noncontrolling owners. Noncontrolling interests that are redeemable or may become redeemable at a fixed or determinable price at the option of the holder or upon the occurrence of an event outside of the control of the Company are presented in mezzanine equity on the condensed consolidated balance sheets.

Throughout these notes to the condensed consolidated financial statements, Community Health Systems, Inc. (the “Parent”), and its consolidated subsidiaries are referred to on a collective basis as the “Company.” This drafting style is not meant to indicate that the publicly-traded Parent or any subsidiary of the Parent owns or operates any asset, business, or property. The hospitals, operations and businesses described in this filing are owned and operated, and management services provided, by distinct and indirect subsidiaries of Community Health Systems, Inc.

Allowance for Doubtful Accounts . Accounts receivable are reduced by an allowance for amounts that could become uncollectible in the future. Substantially all of the Company’s receivables are related to providing healthcare services to its hospitals’ patients.

The Company estimates the allowance for doubtful accounts by reserving a percentage of all self-pay accounts receivable without regard to aging category, based on collection history, adjusted for expected recoveries and, if present, anticipated changes in trends. For all other non-self-pay payor categories, the Company reserves 100% of all accounts aging over 365 days from the date of discharge. The percentage used to reserve for all self-pay accounts is based on the Company’s collection history. The Company collects substantially all of its third-party insured receivables, which include receivables from governmental agencies.

Collections are impacted by the economic ability of patients to pay and the effectiveness of the Company’s collection efforts. Significant changes in payor mix, business office operations, economic conditions or trends in federal and state governmental healthcare coverage could affect the Company’s collection of accounts receivable and the estimates of the collectability of future accounts receivable. The process of estimating the allowance for doubtful accounts requires the Company to estimate the collectability of self-pay accounts receivable, which is primarily based on its collection history, adjusted for expected recoveries and, if present, anticipated changes in collection trends. The Company also continually reviews its overall reserve adequacy by monitoring historical cash collections as a percentage of trailing net revenue less provision for bad debts, as well as by analyzing current period net revenue and admissions by payor classification, aged accounts receivable by payor, days revenue outstanding, and the impact of recent acquisitions and dispositions.

Operating revenues, net of contractual allowances and discounts (but before the provision for bad debts), recognized during the three and six months ended June 30, 2013 and 2012, were as follows (in thousands):

Electronic Health Records Incentive Reimbursement.  The American Recovery and Reinvestment Act of 2009 included provisions for implementing health information technology under the Health Information Technology for Economic and Clinical Health Act (“HITECH”). These provisions were designed to increase the use of electronic health records (“EHR”) technology and establish the requirements for a Medicare and Medicaid incentive payments program beginning in 2011 for eligible hospitals and providers that adopt and meaningfully use certified EHR technology. The Company utilizes a gain contingency model to recognize EHR incentive payments. Recognition occurs when our eligible hospitals adopt or demonstrate meaningful use of certified EHR technology for the applicable payment period and have available the Medicare cost report information for the relevant full cost report year used to determine the final incentive payment.

Medicaid EHR incentive payments are calculated based on prior period Medicare cost report information available at the time when eligible hospitals adopt, implement or demonstrate meaningful use of certified EHR technology. Since the information for the relevant full Medicare cost report year is available, the incentive income from resolving the gain contingency is recognized when eligible hospitals adopt, implement or demonstrate meaningful use of certified EHR technology.

Medicare EHR incentive payments are calculated based on the Medicare cost report information for the full cost report year that began during the federal fiscal year in which meaningful use is demonstrated. Since the necessary information is only available at the end of the relevant full Medicare cost report year, the incentive income from resolving the gain contingency is recognized when eligible hospitals demonstrate meaningful use of certified EHR technology and the information for the applicable full Medicare cost report year to determine the final incentive payment is available.

In some instances, the Company may receive estimated Medicare EHR incentive payments prior to when the Medicare cost report information used to determine the final incentive payment is available. In these instances, recognition of the gain for EHR incentive payments is deferred until all recognition criteria described above are met.

Eligibility for annual Medicare incentive payments is dependent on providers demonstrating meaningful use of EHR technology. Initial Medicaid incentive payments were available to providers that adopt, implement or upgrade certified EHR technology; however, providers must demonstrate meaningful use of such technology in subsequent years to qualify for additional incentive payments. Medicaid EHR incentive payments are fully funded by the federal government and administered by the states; however, the states are not required to offer EHR incentive payments to providers.

The Company recognized approximately $24.4 million and $16.8 million for the three months ended June 30, 2013 and 2012, respectively, and $45.3 million and $43.0 million during the six months ended June 30, 2013 and 2012, respectively, of incentive reimbursement for HITECH incentives from Medicare and Medicaid related to certain of the Company’s hospitals and for certain of the Company’s employed physicians that have demonstrated meaningful use of certified EHR technology or have completed attestations to their adoption or implementation of certified EHR technology. These incentive reimbursements are presented as a reduction of operating costs and expenses on the condensed consolidated statements of income. The Company received cash related to the incentive reimbursement for HITECH incentives of approximately $37.6 million and $22.6 million for the three months ended June 30, 2013 and 2012, respectively, and $82.7 million and $28.8 million for the six months ended June 30, 2013 and 2012, respectively. As of June 30, 2013 and 2012, $50.2 million and $1.0 million, respectively, were recorded as deferred revenue as all criteria for gain recognition had not been met.

Reimbursement Settlement . Included in net operating revenues for the six months ended June 30, 2012 on a non-same store basis is approximately $101.8 million of net operating revenues from an industry-wide settlement with the United States Department of Health and Human Services and Centers for Medicare and Medicaid Services, based on a claim that acute-care hospitals in the U.S. were underpaid from the Medicare inpatient prospective payment system in federal fiscal years 1999 through 2011. The underpayments resulted from calculations related to the rural floor budget neutrality adjustments implemented in connection with the Balanced Budget Act of 1997. During the three months ended June 30, 2012, the Company received $100.6 million of cash from this settlement. Also included in net operating revenues for the six months ended June 30, 2012 is an unfavorable adjustment of approximately $21.0 million related to the revised Supplemental Security Income ratios issued for federal fiscal years 2006 through 2009 utilized for calculating Medicare Disproportionate Share Hospital reimbursements.

2.  ACCOUNTING FOR STOCK-BASED COMPENSATION

Stock-based compensation awards have been granted under the Community Health Systems, Inc. Amended and Restated 2000 Stock Option and Award Plan, amended and restated as of March 20, 2013 (the “2000 Plan”), and the Community Health Systems, Inc. 2009 Stock Option and Award Plan, amended and restated as of March 20, 2013 (the “2009 Plan”).

The 2000 Plan allowed for the grant of incentive stock options intended to qualify under Section 422 of the Internal Revenue Code (the “IRC”), as well as stock options which do not so qualify, stock appreciation rights, restricted stock, restricted stock units, performance-based shares or units and other share awards. Prior to being amended in 2009, the 2000 Plan also allowed for the grant of phantom stock. Persons eligible to receive grants under the 2000 Plan include the Company’s directors, officers, employees and consultants. All options granted under the 2000 Plan have been “nonqualified” stock options for tax purposes. Generally, vesting of these granted options occurs in one-third increments on each of the first three anniversaries of the award date. Options granted prior to 2005 have a 10-year contractual term, options granted in 2005 through 2007 have an eight-year contractual term and options granted in 2008 through 2011 have a 10-year contractual term. Since the Company’s stockholders approved the March 20, 2013 amendment and restatement of the 2009 Plan, no further shares will be awarded under the 2000 plan.

The 2009 Plan provides for the grant of incentive stock options intended to qualify under Section 422 of the IRC and for the grant of stock options which do not so qualify, stock appreciation rights, restricted stock, restricted stock units, performance-based shares or units and other share awards. Persons eligible to receive grants under the 2009 Plan include the Company’s directors, officers, employees and consultants. To date, all options granted under the 2009 Plan have been “nonqualified” stock options for tax purposes. Generally, vesting of these granted options occurs in one-third increments on each of the first three anniversaries of the award date. Options granted in 2011 or later have a 10-year contractual term. As of June 30, 2013, 4,170,996 shares of unissued common stock were reserved for future grants under the 2009 Plan.

The exercise price of all options granted is equal to the fair value of the Company’s common stock on the option grant date.

At June 30, 2013, $47.7 million of unrecognized stock-based compensation expense was expected to be recognized over a weighted-average period of 24 months. Of that amount, $4.1 million related to outstanding unvested stock options was expected to be recognized over a weighted-average period of 12 months and $43.6 million related to outstanding unvested restricted stock and restricted stock units was expected to be recognized over a weighted-average period of 25 months. There were no modifications to awards during the three and six months ended June 30, 2013.

No stock options were granted during the three and six months ended June 30, 2013. The fair value of stock options granted during the three and six months ended June 30, 2012 was estimated using the Black Scholes option pricing model with the following assumptions:

In determining the expected term, the Company examined concentrations of option holdings and historical patterns of option exercises and forfeitures, as well as forward-looking factors, in an effort to determine if there were any discernible employee populations. From this analysis, the Company identified two primary employee populations, one consisting of certain senior executives and the other one consisting of substantially all other recipients.

The expected volatility rate was estimated based on historical volatility. In determining expected volatility, the Company also reviewed the market-based implied volatility of actively traded options of its common stock and determined that historical volatility utilized to estimate the expected volatility rate did not differ significantly from the implied volatility.

The expected term computation is based on historical exercise and cancellation patterns and forward-looking factors, where present, for each population identified. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of the grant. The pre-vesting forfeiture rate is based on historical rates and forward-looking factors for each population identified. The Company adjusts the estimated forfeiture rate to its actual experience.

Options outstanding and exercisable under the 2000 Plan and the 2009 Plan as of June 30, 2013, and changes during each of the three-month periods following December 31, 2012, were as follows (in thousands, except share and per share data):

The weighted-average grant date fair value of stock options granted during the three and six months ended June 30, 2012 was $10.01 and $9.16, respectively. No stock options were granted during the three and six months ended June 30, 2013. The aggregate intrinsic value (the number of in-the-money stock options multiplied by the difference between the Company’s closing stock price on the last trading day of the reporting period ($46.88) and the exercise price of the respective stock options) in the table above represents the amount that would have been received by the option holders had all option holders exercised their options on June 30, 2013. This amount changes based on the market value of the Company’s common stock. The aggregate intrinsic value of options exercised during the three months ended June 30, 2013 and 2012 was $9.6 million and $0.3 million, respectively. The aggregate intrinsic value of options exercised during the six months ended June 30, 2013 and 2012 was $28.9 million and $0.4 million, respectively. The aggregate intrinsic value of options vested and expected to vest approximates that of the outstanding options.

The Company has also awarded restricted stock under the 2000 Plan and the 2009 Plan to its directors and employees of certain subsidiaries. The restrictions on these shares generally lapse in one-third increments on each of the first three anniversaries of the award date. Certain of the restricted stock awards granted to the Company’s senior executives contain a performance objective that must be met in addition to any vesting requirements. If the performance objective is not attained, the awards will be forfeited in their entirety. Once the performance objective has been attained, restrictions will lapse in one-third increments on each of the first three anniversaries of the award date. Notwithstanding the above-mentioned performance objectives and vesting requirements, the restrictions will lapse earlier in the event of death, disability or termination of employment by the Company for any reason other than for cause of the holder of the restricted stock, or change in control of the Company. Restricted stock awards subject to performance standards are not considered outstanding for purposes of determining earnings per share until the performance objectives have been satisfied.

Under the Directors’ Fees Deferral Plan, the Company’s outside directors may elect to receive share equivalent units in lieu of cash for their directors’ fees. These share equivalent units are held in the plan until the director electing to receive the share equivalent units retires or otherwise terminates his/her directorship with the Company. Share equivalent units are converted to shares of common stock of the Company at the time of distribution based on the closing market price of the Company’s common stock on that date. The following table represents the amount of directors’ fees which were deferred during each of the respective periods, and the number of share equivalent units into which such directors’ fees would have converted had each of the directors who had deferred such fees retired or terminated his/her directorship with the Company as of the end of the respective periods (in thousands, except share equivalent units):

At June 30, 2013, a total of 29,448 share equivalent units were deferred in the plan with an aggregate fair value of $1.4 million, based on the closing market price of the Company’s common stock at June 30, 2013 of $46.88.

3.  COST OF REVENUE

Substantially all of the Company’s operating costs and expenses are “cost of revenue” items. Operating costs that could be classified as general and administrative by the Company would include the Company’s corporate office costs at its Franklin, Tennessee office, which were $47.6 million and $56.6 million for the three months ended June 30, 2013 and 2012, respectively, and $93.0 million and $104.2 million for the six months ended June 30, 2013 and 2012, respectively. Included in these amounts is stock-based compensation expense of $9.5 million and $10.1 million for the three months ended June 30, 2013 and 2012, respectively, and $19.4 million and $20.6 million for the six months ended June 30, 2013 and 2012, respectively.

4.  USE OF ESTIMATES

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements. Actual results could differ from these estimates under different assumptions or conditions.

5.  ACQUISITIONS AND DIVESTITURES

Acquisitions

The Company accounts for all transactions that represent business combinations using the acquisition method of accounting, where the identifiable assets acquired, the liabilities assumed and any noncontrolling interest in the acquired entity are recognized and measured at their fair values on the date the Company obtains control in the acquiree. Such fair values that are not finalized for reporting periods following the acquisition date are estimated and recorded as provisional amounts. Adjustments to these provisional amounts during the measurement period (defined as the date through which all information required to identify and measure the consideration transferred, the assets acquired, the liabilities assumed and any noncontrolling interests has been obtained, limited to one year from the acquisition date) are recorded as of the date of acquisition. Any material impact to comparative information for periods after acquisition, but before the period in which adjustments are identified, is reflected in those prior periods as if the adjustments were considered as of the acquisition date. Goodwill is determined as the excess of the fair value of the consideration conveyed in the acquisition over the fair value of the net assets acquired.

6.  INCOME TAXES

The total amount of unrecognized benefit that would affect the effective tax rate, if recognized, was approximately $0.9 million as of June 30, 2013. A total of approximately $0.5 million of interest and penalties is included in the amount of the liability for uncertain tax positions at June 30, 2013. It is the Company’s policy to recognize interest and penalties related to unrecognized benefits in its condensed consolidated statements of income as income tax expense.

The Company, or one of its subsidiaries, files income tax returns in the United States federal jurisdiction and various state jurisdictions. The Company has extended the federal statute of limitations through December 31, 2013 for Triad Hospitals, Inc. (“Triad”) for the tax periods ended December 31, 1999, December 31, 2000, April 30, 2001, June 30, 2001, December 31, 2001, December 31, 2002, December 31, 2003, December 31, 2004, December 31, 2005, December 31, 2006 and July 25, 2007. With few exceptions, the Company is no longer subject to state income tax examinations for years prior to 2009. The Company’s federal income tax returns for the 2009 and 2010 tax years are currently under examination by the Internal Revenue Service (“IRS”). The Company believes the results of these examinations will not be material to its consolidated results of operations or consolidated financial position. During the three months ended June 30, 2013, the IRS concluded its examination of the federal tax return of Community Health Systems, Inc. for the tax periods ended December 31, 2007 and 2008. The results of these examinations did not have a material effect to the Company’s consolidated results of operations or consolidated financial position. The Company has extended the federal statute of limitations for Community Health Systems, Inc. for the tax periods ended December 31, 2007 and 2008 through April 30, 2014 and for the tax period ended December 31, 2009 through July 18, 2014.

Cash paid for income taxes, net of refunds received, resulted in net cash paid of $70.8 million and $22.1 million for the three months ended June 30, 2013 and 2012, respectively, and $70.4 million and $22.0 million during the six months ended June 30, 2013 and 2012, respectively.

Goodwill is allocated to each identified reporting unit, which is defined as an operating segment or one level below the operating segment (referred to as a component of the entity). Management has determined that the Company’s operating segments and hospital management services operations meet the criteria to be classified as reporting units. At June 30, 2013, the hospital operations reporting unit, the home care agency operations reporting unit, and the hospital management services reporting unit had approximately $4.3 billion, $43.6 million and $33.3 million, respectively, of goodwill.

Goodwill is evaluated for impairment at the same time every year and when an event occurs or circumstances change that, more likely than not, reduce the fair value of the reporting unit below its carrying value. There is a two-step method for determining goodwill impairment. Step one is to compare the fair value of the reporting unit with the unit’s carrying amount, including goodwill. If this test indicates the fair value is less than the carrying value, then step two is required to compare the implied fair value of the reporting unit’s goodwill with the carrying value of the reporting unit’s goodwill. The Company performed its last annual goodwill evaluation during the fourth quarter of 2012. No impairment was indicated by this evaluation. The next annual goodwill evaluation will be performed during the fourth quarter of 2013.

The Company estimates the fair value of the related reporting units using both a discounted cash flow model as well as an EBITDA multiple model. The cash flow forecasts are adjusted by an appropriate discount rate based on the Company’s estimate of a market participant’s weighted-average cost of capital. These models are both based on the Company’s best estimate of future revenues and operating costs and are reconciled to the Company’s consolidated market capitalization, with consideration of the amount a potential acquirer would be required to pay, in the form of a control premium, in order to gain sufficient ownership to set policies, direct operations and control management decisions.

Approximately $0.6 million of intangible assets other than goodwill were acquired during the six months ended June 30, 2013. The gross carrying amount of the Company’s other intangible assets subject to amortization was $57.2 million at June 30, 2013 and $61.9 million at December 31, 2012, and the net carrying amount was $23.8 million at June 30, 2013 and $26.3 million at December 31, 2012. The carrying amount of the Company’s other intangible assets not subject to amortization was $48.3 million at June 30, 2013 and $48.1 million at December 31, 2012. Other intangible assets are included in other assets, net on the Company’s consolidated balance sheets. Substantially all of the Company’s intangible assets are contract-based intangible assets related to operating licenses, management contracts, or non-compete agreements entered into in connection with prior acquisitions.

The weighted-average amortization period for the intangible assets subject to amortization is approximately eight years. There are no expected residual values related to these intangible assets. Amortization expense on these intangible assets was $1.4 million and $1.9 million for the three months ended June 30, 2013 and 2012, respectively, and $2.9 million and $3.7 million during the six months ended June 30, 2013 and 2012, respectively. Amortization expense on intangible assets is estimated to be $2.9 million for the remainder of 2013, $4.2 million in 2014, $3.4 million in 2015, $2.4 million in 2016, $2.2 million in 2017, $2.0 million in 2018 and $6.7 million thereafter.

The gross carrying amount of capitalized software for internal use was approximately $826.0 million and $654.4 million at June 30, 2013 and December 31, 2012, respectively, and the net carrying amount considering accumulated amortization was approximately $467.3 million and $354.4 million at June 30, 2013 and December 31, 2012, respectively. The estimated amortization period for capitalized internal-use software is generally three years, except for capitalized costs related to significant system conversions, which is generally eight to ten years. There is no expected residual value for capitalized internal-use software. At June 30, 2013, there was approximately $139.4 million of capitalized costs for internal-use software that is currently in the development stage and will begin amortization once the software project is complete and ready for its intended use. Amortization expense on capitalized internal-use software was $34.6 million and $21.7 million for the three months ended June 30, 2013 and 2012, respectively, and $65.1 million and $41.4 million during the six months ended June 30, 2013 and 2012, respectively. Amortization expense on capitalized internal-use software is estimated to be $62.8 million for the remainder of 2013, $125.7 million in 2014, $131.2 million in 2015, $41.9 million in 2016, $30.9 million in 2017, $24.7 million in 2018 and $50.1 million thereafter.
