Description of Business and Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Description of Business and Significant Accounting Policies	Description of Business and Significant Accounting Policies Nature of Operations We provide management, administrative and operating expertise and services to the housekeeping, laundry, linen, facility maintenance and dietary service departments of the health care industry, including nursing homes, retirement complexes, rehabilitation centers and hospitals located throughout the United States. Although we do not directly participate in any government reimbursement programs, our clients’ reimbursements are subject to government regulation. Therefore, they are directly affected by any legislation relating to Medicare and Medicaid reimbursement programs. We provide our services primarily pursuant to full service agreements with our clients. In such agreements, we are responsible for the day to day management of the employees located at our clients’ facilities. We also provide services on the basis of a management-only agreement for a very limited number of clients. Our agreements with clients typically provide for a one year service term, cancelable by either party upon 30 to 90 days’ notice, after the initial 60 to 120 day period. We are organized into two reportable segments; housekeeping, laundry, linen and other services (“Housekeeping”), and dietary department services (“Dietary”). Housekeeping consists of the managing of the client’s housekeeping department which is principally responsible for the cleaning, disinfecting and sanitizing of patient rooms and common areas of a client’s facility, as well as the laundering and processing of the personal clothing belonging to the facility’s patients. Also within the scope of this segment’s service is the responsibility for laundering and processing of the bed linens, uniforms and other assorted linen items utilized by a client facility. Dietary consists of managing the client’s dietary department which is principally responsible for food purchasing, meal preparation and providing dietitian consulting professional services, which includes the development of a menu that meets the patient’s dietary needs. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Healthcare Services Group, Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. Fair Value of Financial Instruments Our financial instruments consist principally of cash and cash equivalents, marketable securities, accounts and notes receivable, deferred compensation funding and accounts payable. Our marketable securities consist of tax-exempt municipal bond investments that are reported at fair value with the unrealized gains and losses included in our consolidated statements of comprehensive income. In accordance with generally accepted accounting principles in the United States ("U.S. GAAP"), we define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value of our cash equivalents and marketable securities is determined based on “Level 2” inputs, which consist of quoted prices for similar assets or market corroborated inputs. We believe recorded values of all of our financial instruments approximate their current fair values because of their nature, stated interest rates and respective maturity dates or durations. We have certain notes receivable that either do not bear interest or bear interest at a below market rate. Therefore, such notes receivable of $6,472,000 and $10,208,000 at December 31, 2015 and 2014, respectively, have been discounted to their present value and are reported at values of $6,460,000 and $10,196,000 at December 31, 2015 and 2014, respectively. Cash and Cash Equivalents Cash and cash equivalents are held in U.S. financial institutions or in custodial accounts with U.S. financial institutions. Cash and cash equivalents are defined as short-term, highly liquid investments with a maturity of three months or less at time of purchase that are readily convertible into cash and have insignificant interest rate risk. Investments in Marketable Securities We define our marketable securities as fixed income investments which are highly liquid investments that can be readily purchased or sold using established markets. At December 31, 2015, we had marketable securities of $69,496,000 which were comprised primarily of tax exempt municipal bonds. These investments are reported at fair value on our balance sheet. For the year ended December 31, 2015, the accumulated other comprehensive income on our consolidated balance sheet, statements of comprehensive income and stockholders’ equity includes unrealized gains from marketable securities of $543,000 related to marketable securities which are not recognized under the fair value option in accordance with U.S. GAAP. The unrealized gains and losses are recorded net of income taxes. We, in accordance with U.S. GAAP, define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We have not elected the fair value option for our available for sale marketable securities as we believe these assets are more representative of our investing activities and are viewed as non-operating in nature. These assets are available for future needs of the Company to support our current and projected growth, if required. In accordance with U.S. GAAP, our investments in marketable securities are classified within Level 2 of the fair value hierarchy. These investment securities are valued based upon quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Our investment policy is to seek to manage these assets to achieve our goal of preserving principal, maintaining adequate liquidity at all times, and maximizing returns subject to our investment guidelines. Our investment policy limits investment to certain types of instruments issued by institutions primarily with investment grade credit ratings and places restrictions on concentration by type and issuer. We periodically review our investments in marketable securities for other than temporary declines in fair value below the cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. As of December 31, 2015, we believe that recorded value of our investments in marketable securities was recoverable in all material respects. Inventories and Supplies Inventories and supplies include housekeeping, linen and laundry supplies, as well as food provisions and supplies. Inventories and supplies are stated at cost to approximate a first-in, first-out (FIFO) basis. Linen supplies are amortized on a straight-line basis over their estimated useful life of 24 months. Property and Equipment Property and equipment are stated at cost. Additions, renewals and improvements are capitalized, while maintenance and repair costs are expensed when incurred. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the respective accounts and any resulting gain or loss is included in income. Depreciation is provided by the straight-line method over the following estimated useful lives: laundry and linen equipment installations — 3 to 7 years; housekeeping, and office furniture and equipment — 3 to 7 years; autos and trucks — 3 years. Depreciation expense on property and equipment for the years ended December 31, 2015, 2014 and 2013 was $4,419,000, $3,946,000 and $3,373,000, respectively. Revenue Recognition Revenues from our service agreements with clients are recognized as services are performed. Revenues are reported net of sales taxes that are collected from customers and remitted to taxing authorities. As a distributor of laundry equipment, we occasionally sell laundry installations to certain clients. The sales in most cases represent the construction and installation of a turn-key operation and are for payment terms ranging from 24 to 60 months. Our accounting policy for these sales is to recognize the gross profit over the life of the payments associated with our financing of the transactions. During 2015, 2014 and 2013, laundry installation sales were not material. Income Taxes We use the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. We accrue for probable tax obligations as required by facts and circumstances in the various regulatory environments. In addition, deferred tax assets and liabilities are recognized for expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. If appropriate, we would record a valuation allowance to reduce deferred tax assets to an amount for which realization is more likely than not. Deferred tax assets and liabilities are more fully described in subsequent Note 13. In accordance with U.S. GAAP, we account for uncertain income tax positions reflected within our financial statements based on a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Earnings per Common Share Basic earnings per common share are computed by dividing income available to common shareholders by the weighted-average common shares outstanding for the period. Diluted earnings per common share reflect the weighted-average common shares outstanding and dilutive common shares, such as those issuable upon exercise of stock options. Share-Based Compensation U.S. GAAP addresses the accounting for share-based compensation, specifically, the measurement and recognition of compensation expense, based on estimated fair values, for all share-based awards made to employees and directors, including stock options and participation in the Company’s employee stock purchase plan. We estimate the fair value of share-based awards on the date of grant using the Black-Scholes option valuation model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense in the Company’s consolidated statements of income over the requisite service periods. We use the straight-line single option method of expensing share-based awards in our consolidated financial statements of income. Because share-based compensation expense is based on awards that are ultimately expected to vest, share-based compensation expense will be reduced to account for estimated forfeitures. Forfeitures are to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Advertising Costs Advertising costs are expensed when incurred. Advertising costs were not material for the years ended December 31, 2015, 2014 and 2013. Impairment of Long-Lived Assets We account for long-lived assets in accordance with the criteria established in U.S. GAAP, which states that the carrying amounts of long-lived assets be periodically reviewed to determine whether current events or circumstances warrant adjustment to such carrying amounts. Any impairment is measured by the amount that the carrying value of such assets exceeds their fair value, primarily based on estimated discounted cash flows. Considerable management judgment is necessary to estimate the fair value of assets. Assets to be disposed of are carried at the lower of their financial statement carrying amount or fair value, less cost to sell. Acquisitions We acquire businesses and/or assets that augment and complement our operations from time to time. These acquisitions are accounted for under the purchase method of accounting. The consolidated financial statements include the results of operations from such business combinations as of the date of acquisition. Identifiable Intangible Assets and Goodwill Identifiable intangible assets with finite lives are amortized on a straight-line basis over their respective lives. Goodwill represents the excess of costs over the fair value of net assets of the acquired business. We review the carrying values of goodwill at least annually during the fourth quarter of each year to assess impairment because these assets are not amortized. Additionally, we review the carrying value of any intangible asset or goodwill whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. We assess impairment by comparing the fair value of an identifiable intangible asset or reporting unit with its carrying value. Impairments are recorded when incurred. No impairment loss was recognized on our intangible assets and goodwill for the years ended December 31, 2015, 2014 or 2013. Treasury Stock Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Gains or losses on the subsequent reissuance of shares are credited or charged to additional paid in capital. Reclassification Certain prior period amounts have been reclassified to conform to current year presentation. Use of Estimates in Financial Statements In preparing financial statements in conformity with U.S. GAAP, we make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates are used for, but not limited to, our allowance for doubtful accounts, accrued insurance claims, asset valuations and review for potential impairment, and deferred taxes. The estimates are based upon various factors including current and historical trends, as well as other pertinent industry and regulatory authority information. We regularly evaluate this information to determine if it is necessary to update the basis for our estimates and to compensate for known changes. Change in Accounting Estimate In fiscal year 2015, the Company transitioned its workers compensation and certain employee health & welfare insurance programs to HCSG Insurance Corp. ("HCSG Insurance" or the "Captive"), its wholly owned captive insurance subsidiary which was previously providing general liability coverage to the Company. HCSG Insurance was formed in January 2014 to provide the Company with greater flexibility and cost efficiency in meeting its property & casualty and health & welfare needs. In conjunction with the aforementioned insurance programs being administered and provided by the Captive, during the third quarter 2014, management conducted a review of its self-insurance reserves to enhance its self-insurance estimation process. After analysis and consultation with insurance regulators and advisors, the Company recorded a non-cash adjustment of $37,416,000 to reflect estimated current and future insurance claims projected to be closed out over the next 15 to 17 years. This tax-effected adjustment was recorded in the third quarter 2014 and is accounted for as a change in estimate, along with charges related to the corporate reorganization, self-funded health insurance program transition and other related expenses in our consolidated statements of comprehensive income. Concentrations of Credit Risk The accounting guidance requires the disclosure of significant concentrations of credit risk, regardless of the degree of such risk. Financial instruments, as defined by U.S. GAAP, which potentially subject us to concentrations of credit risk, consist principally of cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. We define our marketable securities as fixed income investments which are highly liquid investments that can be readily purchased or sold using established markets. At December 31, 2015 and 2014, substantially all of our cash and cash equivalents, and marketable securities were held in one large financial institution located in the United States. Our clients are concentrated in the health care industry, primarily providers of long-term care. Many of our clients’ revenues are highly contingent on Medicare, Medicaid and third party payors’ reimbursement funding rates. Congress has enacted a number of major laws during the past decade that have significantly altered, or threatened to alter, overall government reimbursement for nursing home services. These changes and lack of substantive reimbursement funding rate reform legislation, as well as other trends in the long-term care industry have affected and could adversely affect the liquidity of our clients, resulting in their inability to make payments to us on agreed upon payment terms. These factors, in addition to delays in payments from clients, have resulted in, and could continue to result in, significant additional bad debts in the future. State Medicaid programs are experiencing increased demand, and with lower revenues than projected, they have fewer resources to support their Medicaid programs. In addition, comprehensive health care legislation under the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (together, the “Act”) was signed into law in March 2010. The Act will significantly impact the governmental healthcare programs in which our clients participate, and reimbursements received thereunder from governmental or third-party payors. Furthermore, in the coming year and beyond, new proposals or additional changes in existing regulations could be made to the Act which could directly impact the governmental reimbursement programs in which our clients participate. As a result, some state Medicaid programs are reconsidering previously approved increases in nursing home reimbursement or are considering delaying or foregoing those increases. A few states have indicated that it is possible they will run out of cash to pay Medicaid providers, including nursing homes. Any negative changes in our clients’ reimbursements may negatively impact our results of operations. In 2009 and 2010, Federal economic stimulus legislation was enacted to counter the impact of the economic crisis on state budgets. The legislation included the temporary provision of additional federal matching funds to help states maintain their Medicaid programs. This legislation to provide states with an extension of this fiscal relief was extended through June 2011, but at a reduced reimbursement rate. In July 2011, CMS issued a final rule that reduced Medicare payments to nursing centers by 11.1% and changed the reimbursement for the provision of group rehabilitation therapy services to Medicare beneficiaries. This new rule was effective as of October 1, 2011. Even if federal or state legislation is enacted that provides additional funding to Medicaid providers, given the volatility of the economic environment, it is difficult to predict the impact of this legislation on our clients’ liquidity and their ability to make payments to us as agreed. In January 2013, the U.S. Congress enacted the American Taxpayer Relief Act of 2012, which delayed automatic spending cuts, including reduced Medicare payments to plans and providers up to 2%. These discretionary spending caps were originally enacted under provisions in the Budget Control Act of 2011, an initiative to reduce the federal deficit through 2021, also known as “sequestration.” The sequestration went into effect starting March 2013. In December 2013, the U.S. Congress enacted the Bipartisan Budget Act of 2013, which reduces the impact of the sequestration over the next two years. This began in fiscal year 2014 and extended the reduction in Medicare payments to plans and providers for two years from 2021 through 2023. Significant Clients We have several clients who each have made a contribution to our total consolidated revenues ranging from 3% to 9% for the year ended December 31, 2015. Although we expect to continue relationships with these clients, there can be no assurance thereof. The loss of such clients, or a significant reduction in the revenues we receive from these clients, would have a material adverse effect on the results of operations of our two operating segments. In addition, if such clients change their respective payment terms it could increase our accounts receivable balance and have a material adverse effect on our cash flows and cash and cash equivalents. Recent Accounting Pronouncements In November 2015, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2015-17, Balance Sheet Classification of Deferred Taxes. The amendment in this ASU requires that deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent in a classified statement of financial position. The guidance becomes effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company does not expect the guidance in this ASU to have a material impact on our consolidated financial statements and related disclosures. In September 2015, the Financial Accounting Standards Board issued ASU 2015-16, Business Combinations (Topic 805). The amendments in this ASU require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Additionally, this ASU requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. To simplify the accounting for adjustments made to provisional amounts recognized in a business combination, the amendments in this ASU eliminate the requirement to retrospectively account for those adjustments. This ASU is effective prospectively for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years.The Company does not expect the guidance in this ASU to have a material impact on our consolidated financial statements and related disclosures. In August 2015, the Financial Accounting Standards Board issued ASU 2015-14, Revenue from Contracts with Customer (Topic 606): Deferral of the Effective Date. This ASU defers the effective date of ASU 2014-09, Revenue from Contracts with Customer (Topic 606) for all entities by one year. As a result, all entities will be required to apply the provisions of ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently assessing the adoption date and impact the guidance in this ASU will have, if any, on our consolidated results of operations, cash flows, or financial position. In June 2015, the Financial Accounting Standards Board issued ASU 2015-10, Technical Corrections and Improvements. The amendments in this ASU represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. Additionally, some of the amendments will make the Codification easier to understand and easier to apply by eliminating inconsistencies, providing needed clarifications, and improving the presentation of guidance in the Codification. This ASU is effective for fiscal years and interim periods beginning on or after December 15, 2015, with early adoption permitted. The Company does not expect the guidance in this ASU to have a material impact on our consolidated financial statements and related disclosures.

Acquisition

Business Combinations [Abstract]

Acquisition

On July 12, 2013, the Company acquired substantially all of the operating assets of Platinum Health Services, LLC, a Delaware limited liability company and Platinum Health Services PEO, LLC, a Delaware limited liability company (collectively “Platinum”). Platinum was a privately-held provider of professional housekeeping, laundry and maintenance services to long-term and post-acute care facilities and operated within the United States. The acquisition has been included within the consolidated results of operations and financial condition from the date of the acquisition.

The total purchase consideration was $50,766,000, which consisted of a cash payment of $5,000,000, the issuance of 1,215,000 shares of the Company's common stock with a fair value of $30,062,000 and contingent consideration with a fair value of $15,704,000 as of December 31, 2014.

Upon the achievement of certain financial and retention targets, the Platinum stockholders were eligible for contingent consideration paid by the future issuance of 1,005,000 shares of the Company's common stock. As of December 31, 2015, all shares of contingent consideration were earned and distributed to the Platinum stockholders. The Company's obligation to pay contingent consideration has been appropriately classified as equity within the financial statements.

The purchase consideration of the acquisition has been allocated to the assets acquired and liabilities assumed based on estimated fair values. The purchase price allocation was completed in the second quarter of 2014. The purchase price allocation is as follows:



	Purchase Price Allocation
	Preliminary		Adjustments			Final
Fair value of assets acquired, net of liabilities assumed	$	2,604,000	$	(621,000	)	$	1,983,000
Goodwill	23,228,000		4,255,000			27,483,000
Intangible assets	21,000,000		300,000			21,300,000
Net assets acquired	$	46,832,000	$	3,934,000		$	50,766,000

Goodwill, which is expected to be amortized for tax purposes, represents the excess of the purchase price over the fair value of the net assets acquired, and is primarily attributable to the assembled workforce of the acquired business. Goodwill was allocated to our Housekeeping reportable operating segment. Intangible assets consist of customer relationships of $21,300,000 and has been assigned an estimated useful life of 10 years.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Property, Plant and Equipment [Abstract]

Property and Equipment

Property and equipment is recorded at cost. Depreciation is recorded over the estimated useful life of each class of depreciable assets, and is computed using the straight-line method. Leasehold improvements are amortized over the shorter of the estimated asset life or term of the lease. Repairs and maintenance costs are charged to expense as incurred.

The following table sets forth the amounts of property and equipment by each class of depreciable assets as of December 31, 2015 and December 31, 2014:



	December 31, 2015		December 31, 2014
Laundry and linen equipment installations	$	1,117,000	$	2,578,000
Housekeeping and office equipment and furniture	29,852,000		33,546,000

Less accumulated depreciation	18,021,000		23,584,000
Total property and equipment, net	13,086,000		12,772,000

Depreciation expense for the years ended December 31, 2015, 2014 and 2013 was $4,419,000, $3,946,000 and $3,373,000 respectively.

Goodwill and Other Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of net assets acquired of businesses and is not amortized. Goodwill is evaluated for impairment on an annual basis, or more frequently if impairment indicators arise, using a fair-value-based test that compares the fair value of the reporting unit to its carrying value. The carrying value of goodwill as of December 31, 2015 and 2014 was $44,438,000 in both periods.

The cost of intangible assets is based on fair values at the date of acquisition. Intangible assets with determinable lives are amortized on a straight-line basis over their estimated useful life (between 7 and 10 years).

The following table sets forth the amounts of our identifiable intangible assets subject to amortization, which were acquired in acquisitions.



	December 31,
	2015		2014
Customer relationships	$	35,781,000	$	35,781,000
Non-compete agreements	800,000		800,000
Total other intangibles, gross	36,581,000		36,581,000
Less accumulated amortization	19,473,000		16,232,000
Other intangibles, net	$	17,108,000	$	20,349,000

The customer relationships and non-compete agreements have a weighted-average amortization period of eight years. As of December 31, 2014, the Company's non-compete agreements have been fully amortized.

The following table sets forth the estimated amortization expense for intangibles subject to amortization for the following five fiscal years:



Period/Year	Customer Relationships
2016	$	2,699,000
2017	2,427,000
2018	2,328,000
2019	2,130,000
2020	2,130,000
Thereafter	5,394,000

Amortization expense for the years ended December 31, 2015, 2014 and 2013 was $3,241,000, $3,323,000 and $2,831,000, respectively.

- Definition

Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

We, in accordance with U.S. GAAP, define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We have not elected the fair value option for our available for sale marketable securities as we believe these assets are more representative of our investing activities and are viewed as non-operating in nature. These assets are available for future needs of the Company to support our current and projected growth, if required. In accordance with U.S. GAAP, our investments in marketable securities are classified within Level 2 of the fair value hierarchy. These investment securities are valued based upon quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

The Company’s financial instruments consist mainly of cash and cash equivalents, available for sale marketable securities, accounts and notes receivable, prepaid expenses and other, and accounts payable (including income taxes payable and accrued expenses). The carrying value of these financial instruments approximate their fair value because of their short-term nature. The fair value of financial instruments is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties.

The following tables provide fair value measurement information for our marketable securities and deferred compensation fund investment assets as of December 31, 2015 and 2014:

The fair value of the municipal bonds is measured using third party pricing service data. The fair value of equity investments in the funded deferred compensation plan are valued (Level 1) based on quoted market prices. The money market fund in the funded deferred compensation plan is valued (Level 2) at the net asset value (“NAV”) of the shares held by the plan at the end of the period. As a practical expedient, the fair value of our money market fund is valued at the NAV as determined by the custodian of the fund. The money market fund includes short-term United States dollar denominated money-market instruments. The money market fund can be redeemed at its NAV at its measurement date as there are no significant restrictions on the ability of participants to sell this investment. These assets will be redeemed by the plan participants on an as needed basis.

Unrealized gains and losses from marketable securities are recorded in the other comprehensive income caption in our consolidated statements of comprehensive income.

Congress has enacted a number of laws during the past decade that have significantly altered, or may alter, overall government reimbursement for nursing home services. Because our clients’ revenues are generally dependent on Medicare and Medicaid reimbursement funding rates and mechanisms, the overall effect of these laws and trends in the long term care industry have affected and could adversely affect the liquidity of our clients, resulting in their inability to make payments to us on agreed upon payment terms. These factors, in addition to delays in payments from clients, have resulted in and could continue to result in significant additional bad debts in the near future. Whenever possible, when a client falls behind in making agreed-upon payments, we convert the unpaid accounts receivable to interest bearing promissory notes. The promissory notes receivable provide a means by which to further evidence the amounts owed and provide a definitive repayment plan and therefore may ultimately enhance our ability to collect the amounts due. Accounts and notes receivable are stated net of an allowance for doubtful accounts. At December 31, 2015 and 2014, we had $16,830,000 and $16,945,000, net of reserves, respectively, of such promissory notes outstanding. Additionally, we consider restructuring service agreements from full service to management-only service in the case of certain clients experiencing financial difficulties. We believe that such restructurings may provide us with a means to maintain a relationship with the client while at the same time minimizing collection exposure.

Allowance For Doubtful Accounts

Receivables [Abstract]

Allowance for Doubtful Accounts

The allowance for doubtful accounts is established as losses are estimated to have occurred through a provision for bad debts charged to earnings and is included in the costs of services provided caption in our consolidated statements of comprehensive income. The allowance for doubtful accounts is evaluated based on our periodic review of accounts and notes receivable and is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

State Medicaid programs are experiencing increased demand, and with lower revenues than projected, they have fewer resources to support their Medicaid programs. In addition, comprehensive health care legislation under the Act was signed into law in March 2010. The Act will significantly impact the governmental healthcare programs in which our clients participate, and reimbursements received thereunder from governmental or third-party payors. Furthermore, in the coming year and beyond, new proposals or additional changes in existing regulations could be made to the Act which could directly impact the governmental reimbursement programs in which our clients participate. As a result, some state Medicaid programs are reconsidering previously approved increases in nursing home reimbursement or are considering delaying or foregoing those increases. A few states have indicated it is possible they will run out of cash to pay Medicaid providers, including nursing homes. Any negative changes in our clients’ reimbursements may negatively impact our results of operations.

In 2009 and 2010, Federal economic stimulus legislation was enacted to counter the impact of the economic crisis on state budgets. The legislation included the temporary provision of additional federal matching funds to help states maintain their Medicaid programs. This legislation to provide states with an extension of this fiscal relief was extended through June 2011, but at a reduced reimbursement rate. In July 2011, CMS issued a final rule that reduced Medicare payments to nursing centers by 11.1% and changed the reimbursement for the provision of group rehabilitation therapy services to Medicare beneficiaries. This new rule was effective as of October 1, 2011. Even if federal or state legislation is enacted that provides additional funding to Medicaid providers, given the volatility of the economic environment, it is difficult to predict the impact of this legislation on our clients’ liquidity and their ability to make payments to us as agreed.

In January 2013, the U.S. Congress enacted the American Taxpayer Relief Act of 2012, which delayed automatic spending cuts, including reduced Medicare payments to plans and providers up to 2%. These discretionary spending caps were originally enacted under provisions in the Budget Control Act of 2011, an initiative to reduce the federal deficit through 2021, also known as “sequestration.” The sequestration went into effect starting March 2013. In December 2013, the U.S. Congress enacted the Bipartisan Budget Act of 2013, which reduces the impact of the sequestration over the next two years. This began in fiscal year 2014 and extended the reduction in Medicare payments to plans and providers for two years from 2021 through 2023.

We have had varying collection experience with respect to our accounts and notes receivable. When contractual terms are not met, we generally encounter difficulty in collecting amounts due from certain of our clients. Therefore, we have sometimes been required to extend the period of payment for certain clients beyond contractual terms. These clients include those who have terminated service agreements and slow payers experiencing financial difficulties. In order to provide for these collection problems and the general risk associated with the granting of credit terms, we have recorded the following bad debt provisions (in an Allowance for Doubtful Accounts):



	Year Ended December 31,
	2015		2014		2013
Bad debt provision	$	4,335,000	$	4,470,000	$	1,990,000

In making our credit evaluations, in addition to analyzing and anticipating, where possible, the specific cases described above, we consider the general collection risk associated with trends in the long-term care industry. We also establish credit limits, perform ongoing credit evaluation and monitor accounts to minimize the risk of loss. Notwithstanding our efforts to minimize credit risk exposure, our clients could be adversely affected if future industry trends change in such a manner as to negatively impact their cash flows. If our clients experience a negative impact in their cash flows, it would have a material adverse effect on our results of operations and financial condition.

Impaired Notes Receivable

We evaluate our notes receivable for impairment quarterly and on an individual client basis. Notes receivable considered impaired are generally attributable to clients that are either in bankruptcy, are subject to collection activity or those slow payers that are experiencing financial difficulties. In the event that our evaluation results in a determination that a note receivable is impaired, it is valued at the present value of expected cash flows or market value of related collateral. Summary schedules of impaired notes receivable, and the related reserve, for the years ended December 31, 2015, 2014 and 2013 are as follows:



	Impaired Notes Receivable
Year ended December 31,	Balance Beginning of Year		Additions		Deductions		Balance End of Year		Average Outstanding Balance
2015	$	10,208,000	$	395,000	$	4,132,000	$	6,471,000	$	8,340,000
2014	$	2,892,000	$	9,124,000	$	1,808,000	$	10,208,000	$	6,550,000
2013	$	1,639,000	$	1,267,000	$	14,000	$	2,892,000	$	2,266,000



	Reserve for Impaired Notes Receivable

2015	$	3,031,000	$	99,000	$	991,000	$	2,139,000
2014	$	2,019,000	$	2,489,000	$	1,477,000	$	3,031,000
2013	$	958,000	$	1,072,000	$	11,000	$	2,019,000

For impaired notes receivable, interest income is recognized on a cost recovery basis only. As a result, no interest income was recognized on impaired notes receivable. We follow an income recognition policy on all other notes receivable that does not recognize interest income until cash payments are received. This policy was established, recognizing the environment of the long-term care industry, and not because such notes receivable are necessarily impaired. The difference between income recognition on a full accrual basis and cash basis, for notes receivable that are not considered impaired, is not material.

Share-Based Compensation

2012 Equity Incentive Plan

On May 29, 2012, the Company's shareholders adopted and approved the 2012 Equity Incentive Plan (the "2012 Plan"), under which current or prospective officers, employees, non-employee directors and advisors can receive share-based awards such as stock options, restricted stock and other stock awards. The 2012 Plan seeks to promote the highest level of performance by providing an economic interest in the long-term success of the Company. As of the date of shareholder adoption of the 2012 Plan, no further grants were permitted under any previously existing stock plans (the "Pre-existing Plans"). Additionally, all remaining shares available for future grants under the Pre-existing Plans became available for issuance under the 2012 Plan.

In addition to the 2012 Plan, the Company also had two compensation plans at December 31, 2015 which are described below: the Employee Stock Purchase Plan (the “ESPP”) and the Supplemental Executive Retirement Plan (the “SERP”).

The Nominating, Compensation and Stock Option Committee of the Board of Directors is responsible for determining the individuals who will be granted stock awards, the number of stock awards each individual will receive, the price per share (in accordance with the terms of our 2012 Plan), and the exercise period of each stock award.

A summary of stock-based compensation expense for the years ended December 31, 2015, 2014 and 2013 is as follows:



	December 31,
	2015		2014		2013

Total pre-tax stock-based compensation expense charged against income (1)	$	3,542,000	$	3,080,000	$	2,607,000


(1)	Stock-based compensation expense is recorded in the selling, general and administrative caption in our consolidated statements of comprehensive income.

With respect to our SERP, we recorded expense of $538,000, $497,000 and $538,000 (representing the Company’s 25% match of participants’ deferrals) for the years ended December 31, 2015, 2014 and 2013, respectively. Both the SERP match and deferrals are included in the selling, general and administrative caption in our consolidated statements of comprehensive income.

We have outstanding stock awards that were granted under the Pre-existing Plans to non-employee directors, officers and employees of the Company and other specified groups, depending on the Pre-existing Plan. As of December 31, 2015, 4,258,000 shares of common stock were reserved for issuance under our 2012 Plan, including 1,797,000 shares which are available for future grant. The stock price will not be less than the fair market value of the common stock on the date the award is granted. No stock award will have a term in excess of ten years. Since 2008, all awards granted under the Pre-existing Plans or the 2012 Plan become vested and exercisable ratably over a five year period on each yearly anniversary date of the stock grant.

A summary of our stock option activity under the 2012 Plan is as follows:

Employee Stock Purchase Plan

We have an ESPP for all eligible employees. All full-time and certain part-time employees who have completed two years of continuous service with us are eligible to participate. On April 12, 2011, the Board of Directors extended the ESPP for an additional five offerings through 2016. Annual offerings commence and terminate on the respective year’s first and last calendar day.

Under the ESPP, we are authorized to issue up to 4,050,000 shares of our common stock to our employees. Pursuant to such authorization, we have 2,362,000 shares available for future grant at December 31, 2015. Furthermore, under the terms of the ESPP, eligible employees may contribute through payroll deductions up to $21,250 (85% of IRS limitation) of their compensation toward the purchase of the Company's common stock. No employee may purchase common stock which exceeds $25,000 in fair market value (determined on the date of grant) for each calendar year. The price per share is equal to the lower of 85% of the fair market price on the first day of the offering period, or 85% of the fair market price on the day of purchase.

The following table summarizes information about our ESPP annual offerings for the years ended December 31, 2015, 2014 and 2013:

Common shares date of issue	Jan 6, 2016		Jan 7, 2015		Jan 3, 2014

Deferred Compensation Plan

We have a SERP for certain key executives and employees. The SERP is not qualified under Section 401 of the Internal Revenue Code. Effective in Plan year 2010, the Plan was amended to allow participants to defer up to 25% of their earned income on a pre-tax basis. As of the last day of each plan year, each participant will receive a 25% match of up to 15% of their deferral in the form of our Common Stock based on the then current market value. SERP participants fully vest in our matching contribution three years from the first day of the initial year of participation. The income deferred and our matching contributions are unsecured and subject to the claims of our general creditors.

Under the SERP, we are authorized to issue up to 1,013,000 shares of our common stock to our employees. Pursuant to such authorization, we have 421,000 shares available for future grant at December 31, 2015 (after deducting the 2015 funding of 15,000 shares delivered in 2016). In the aggregate, since initiation of the SERP, the Company’s 25% match has resulted in 591,000 shares (including the 2015 funding of shares delivered in 2016) being issued to the trustee. At the time of issuance, such shares were accounted for at cost, as treasury stock. At December 31, 2015, approximately 359,000 of such shares are vested and remain in the respective active participants’ accounts.

The following table summarizes information about our SERP for the plan years ended December 31, 2015, 2014 and 2013:



	SERP Plan Year
	2015				2014			2013

Our Board of Directors reviews our dividend policy on a quarterly basis. Although there can be no assurance that we will continue to pay dividends or the amount of the dividend, we expect to continue to pay a regular quarterly cash dividend. In connection with the establishment of our dividend policy, we adopted a Dividend Reinvestment Plan in 2003.

Tax Provision	$	31,740,000	$	9,858,000		$	19,360,000

Deferred income taxes are recorded using the asset and liability method. Deferred tax assets and liabilities are determined based on differences between the financial reporting and income tax basis of assets and liabilities.

Significant components of our federal and state deferred tax assets and liabilities are as follows:



	Years Ended December 31,
	2015			2014
Net current deferred assets (liabilities):
Allowance for doubtful accounts	$	1,819,000		$	2,427,000

Other	636,000			496,000
	$	11,963,000		$	27,233,000

Realization of the Company’s deferred tax assets is dependent upon future earnings in specific tax jurisdictions, the timing and amount of which are uncertain. Management assesses the Company’s income tax positions and records tax benefits for all years subject to examination based upon an evaluation of the facts, circumstances, and information available at the reporting dates, which include historical operating results and expectations of future earnings. As such, management believes it is more likely than not that the current and noncurrent deferred tax assets recorded will be realized to reduce future income taxes and therefore no valuation allowances are necessary.

A reconciliation of the provision for income taxes and the amount computed by applying the statutory federal income tax rate to income before income taxes is as follows:



	Year Ended December 31,
	2015			2014			2013
Tax expense computed at statutory rate	$	31,418,000		$	11,098,000		$	23,271,000

Management performs an evaluation each period of its tax positions taken and expected to be taken in tax returns. The evaluation is performed on positions relating to tax years that remain subject to examination by major tax jurisdictions, the earliest of which is the tax year ended December 31, 2011. Based on our evaluation, management has concluded that there are no significant uncertain tax positions requiring recognition in our financial statements. Therefore, the table reporting on the change in the liability for unrecognized tax benefits during the year ended December 31, 2015 is omitted as there is no activity to report in such account for the year ended December 31, 2015, and there was no balance of unrecognized tax benefits at the beginning of the year.

We may from time to time be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to our financial results. In the event we have received an assessment for interest and/or penalties, it has been classified in the financial statements as selling, general and administrative expense.

Segment Reporting [Abstract]

Segment Information

Reportable Operating Segments

U.S. GAAP establishes standards for reporting information regarding operating segments in annual financial statements. Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision-maker, or decision-making group in making decisions on how to allocate resources and assess performance.

We manage and evaluate our operations in two reportable segments: Housekeeping (housekeeping, laundry, linen and other services), and Dietary (dietary department services). Although both segments serve the same client base and share many operational similarities, they are managed separately due to distinct differences in the type of service provided, as well as the specialized expertise required of the professional management personnel responsible for delivering the respective segment’s services. We consider the various services provided within each reportable segment to comprise an identifiable reportable operating segment since such services are rendered pursuant to a single service agreement, specific to that reportable segment, as well as the fact that the delivery of the respective reportable segment’s services are managed by the same management personnel of the particular reportable segment.

The Company’s accounting policies for the segments are generally the same as the Company’s significant accounting policies. Differences between the reportable segments’ operating results and other disclosed data and our consolidated financial statements relate primarily to corporate level transactions and recording of transactions at the reportable segment level which use methods other than generally accepted accounting principles. There are certain inventories and supplies that are primarily expensed when incurred within the operating segments, while they are capitalized for the consolidated financial statements. As discussed, most corporate expense is not allocated to the operating segments, and such expenses include corporate salary and benefit costs, certain legal costs, information technology costs, depreciation, amortization of finite lived intangibles, share based compensation costs and other corporate specific costs. Additionally, there are allocations for workers compensation and general liability expense within the operating segments that differ from our actual expense recorded for U.S. GAAP. Segment amounts disclosed are prior to any elimination entries made in consolidation.

Housekeeping provides services in Canada, although essentially all of its revenues and net income, 99% in both categories, are earned in one geographic area, the United States. Dietary provides services solely in the United States.

Earnings Per Common Share

Earnings Per Share [Abstract]

Earnings Per Common Share

Basic net earnings per share are computed using the weighted-average number of common shares outstanding. The dilutive effect of potential common shares outstanding is included in diluted net earnings per share. The computations of basic net earnings per share and diluted net earnings per share for 2015, 2014 and 2013 are as follows:



	Year ended December 31, 2015
	Income (Numerator)		Shares (Denominator)	Per-share Amount

Stock options and unvested restricted stock			725,000	—
Diluted earnings per common share	$	21,850,000	71,341,000	$	0.31

	Year ended December 31, 2013
	Income (Numerator)		Shares (Denominator)	Per-share Amount
	Income (Numerator)		Shares (Denominator)	Per-share Amount
Net income	$	47,129,000
Basic earnings per common share	$	47,129,000	69,206,000	$	0.68
Effect of dilutive securities:

Diluted earnings per common share	$	47,129,000	70,045,000	$	0.67

For the years ended December 31, 2015, 2014 and 2013, options to purchase 918,000, 516,000 and 546,000 shares, respectively, were excluded from the computation of diluted earnings per common share as the exercise price of such options were in excess of the average market value of our common stock at the respective year end.

Other Contingencies	12 Months Ended
Other Contingencies	Dec. 31, 2015
Commitments and Contingencies Disclosure [Abstract]
Other Contingencies	Other Contingencies We have a $200,000,000 bank line of credit on which we may draw to meet short-term liquidity requirements in excess of internally generated cash flow. Amounts drawn under the line of credit are payable upon demand. At December 31, 2015, there were no borrowings under the line of credit. However, at such date, we had outstanding a $78,259,000 (decreased to $68,778,000 on January 1, 2016) irrevocable standby letter of credit which relates to payment obligations under our insurance programs. As a result of the letter of credit issued, the amount available under the line of credit was reduced by $78,259,000 at December 31, 2015. The line of credit requires us to satisfy one financial covenant. We are in compliance with our financial covenant at December 31, 2015 and expect to continue to remain in compliance with such financial covenant. This line of credit expires on December 18, 2018. We believe the line of credit will be renewed at that time. On December 29, 2014, we entered into a Security Interest, Pledge and Assignment of Deposit Account (the "Pledge") with a different bank (the “Bank”) as collateral for the Promissory Note (the “Note”) dated December 29, 2014 between the Company’s third party payroll administrator and the Bank. The Company entered into the Pledge at year end due to the timing of payroll funding and the holidays. On January 2, 2015, the Company's third party payroll administrator satisfied its payment obligation under the Note, and accordingly, the Company's Pledge was terminated. As of December 31, 2014, the cash associated with the Pledge was held in the Company's operating cash account, and used to fund the Company's operations and general operating expenses. The Company concluded that the pledge was immaterial to our statement financial position as it represented less than 6% and 5%, respectively, of current assets and total assets as of December 31, 2014. Additionally, the commitment had no material impact on the Company's consolidated results of operations for the year ended December 31, 2014. We provide our services in 48 states and are subject to numerous local taxing jurisdictions within those states. Consequently, in the ordinary course of business, a jurisdiction may contest our reporting positions with respect to the application of its tax code to our services. A jurisdiction’s conflicting position on the taxability of our services could result in additional tax liabilities. We have tax matters with various taxing authorities. Because of the uncertainties related to both the probable outcome and amount of probable assessment due, we are unable to make a reasonable estimate of a liability. We do not expect the resolution of any of these matters, taken individually or in the aggregate, to have a material adverse effect on our consolidated financial position or results of operations based on our best estimate of the outcomes of such matters. We are also subject to various claims and legal actions in the ordinary course of business. Some of these matters include payroll and employee-related matters and examinations by governmental agencies. As we become aware of such claims and legal actions, we provide accruals if the exposures are probable and estimable. If an adverse outcome of such claims and legal actions is reasonably possible, we assess materiality and provide such financial disclosure, as appropriate. The Company believes it is not a party to, nor are any of its properties the subject of, any pending legal proceeding or governmental examination that would have a material adverse effect on the Company's consolidated financial condition or liquidity. State Medicaid programs are experiencing increased demand, and with lower revenues than projected, they have fewer resources to support their Medicaid programs. In addition, comprehensive health care legislation under the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (together, the “Act”) was signed into law in March 2010. The Act will significantly impact the governmental healthcare programs which our clients participate, and reimbursements received thereunder from governmental or third-party payors. In July 2011, Centers for Medicare and Medicaid Services (“CMS”) issued a final rule that reduced Medicare payments to nursing centers by 11.1% and changed the reimbursement for the provision of group rehabilitation therapy services to Medicare beneficiaries. This rule was effective as of October 1, 2011. Furthermore, in the coming year, new proposals or additional changes in existing regulations could be made to the Act and/or CMS could propose additional reimbursement reductions which could directly impact the governmental reimbursement programs in which our clients participate. As a result, some state Medicaid programs are reconsidering previously approved increases in nursing home reimbursement or are considering delaying or foregoing those increases. A few states have indicated it is possible they will run out of cash to pay Medicaid providers, including nursing homes. In addition, certain state governors have recently stated that they will reject Federal Medicaid assistance under the Act. Any negative changes in our clients’ reimbursements may negatively impact our results of operations. Although we are currently evaluating the Act’s effect on our client base, we may not know the full effect until such time as these laws are fully implemented and CMS and other agencies issue applicable regulations or guidance. In January 2013, the U.S. Congress enacted the American Taxpayer Relief Act of 2012, which delayed automatic spending cuts, including reduced Medicare payments to plans and providers up to 2%. These discretionary spending caps were originally enacted under provisions in the Budget Control Act of 2011, an initiative to reduce the federal deficit through the year 2021, also known as “sequestration.” The sequestration went into effect starting March 2013. In December 2013, the U.S. Congress enacted the Bipartisan Budget Act of 2013, which reduces the impact of the sequestration over the next two years. This began in fiscal year 2014 and extended the reduction in Medicare payments to plans and providers for two years from 2021 through 2023.

Accrued Insurance Claims	12 Months Ended
Accrued Insurance Claims	Dec. 31, 2015
Payables and Accruals [Abstract]
Accrued Insurance Claims	Accrued Insurance Claims We currently have a Paid Loss Retrospective Insurance Plan for general liability and workers’ compensation insurance, which comprise approximately 45% of our liabilities at December 31, 2015. Under our insurance plans for general liability and workers' compensation, predetermined loss limits are arranged with our insurance company to limit both our per occurrence cash outlay and annual insurance plan cost. Our accounting for this plan is affected by various uncertainties, such as historical claims, pay-out experience, demographic factors, industry trends, severity factors, and other actuarial assumption calculated by a third party actuary. Evaluations of our accrued insurance claims estimate as of the balance sheet date are based primarily on current information derived from our actuarial valuation which assist in quantifying and valuing these trends. In the event that our claims experience and/or industry trends result in an unfavorable change resulting from, among other factors, the severity levels of reported claims and medical cost inflation, as compared to historical claim trends, it would have an adverse effect on our results of operations and financial condition. Under these plans, predetermined loss limits are arranged with an insurance company to limit both our per-occurrence cash outlay and annual insurance plan cost. For workers' compensation and general liability, we record a reserve for the estimated future cost of claims and related expenses that have been reported but not settled, including an estimate of claims incurred but not reported that are developed as a result of a review of our historical data and open claims, which is based on estimated provided by a third party actuary.

Description of Business and Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Nature of Operations	We provide management, administrative and operating expertise and services to the housekeeping, laundry, linen, facility maintenance and dietary service departments of the health care industry, including nursing homes, retirement complexes, rehabilitation centers and hospitals located throughout the United States. Although we do not directly participate in any government reimbursement programs, our clients’ reimbursements are subject to government regulation. Therefore, they are directly affected by any legislation relating to Medicare and Medicaid reimbursement programs. We provide our services primarily pursuant to full service agreements with our clients. In such agreements, we are responsible for the day to day management of the employees located at our clients’ facilities. We also provide services on the basis of a management-only agreement for a very limited number of clients. Our agreements with clients typically provide for a one year service term, cancelable by either party upon 30 to 90 days’ notice, after the initial 60 to 120 day period. We are organized into two reportable segments; housekeeping, laundry, linen and other services (“Housekeeping”), and dietary department services (“Dietary”). Housekeeping consists of the managing of the client’s housekeeping department which is principally responsible for the cleaning, disinfecting and sanitizing of patient rooms and common areas of a client’s facility, as well as the laundering and processing of the personal clothing belonging to the facility’s patients. Also within the scope of this segment’s service is the responsibility for laundering and processing of the bed linens, uniforms and other assorted linen items utilized by a client facility. Dietary consists of managing the client’s dietary department which is principally responsible for food purchasing, meal preparation and providing dietitian consulting professional services, which includes the development of a menu that meets the patient’s dietary needs.
Principles of Consolidation	The accompanying consolidated financial statements include the accounts of Healthcare Services Group, Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.
Fair Value of Financial Instruments	Our financial instruments consist principally of cash and cash equivalents, marketable securities, accounts and notes receivable, deferred compensation funding and accounts payable. Our marketable securities consist of tax-exempt municipal bond investments that are reported at fair value with the unrealized gains and losses included in our consolidated statements of comprehensive income. In accordance with generally accepted accounting principles in the United States ("U.S. GAAP"), we define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value of our cash equivalents and marketable securities is determined based on “Level 2” inputs, which consist of quoted prices for similar assets or market corroborated inputs. We believe recorded values of all of our financial instruments approximate their current fair values because of their nature, stated interest rates and respective maturity dates or durations.
Cash and Cash Equivalents	Cash and cash equivalents are held in U.S. financial institutions or in custodial accounts with U.S. financial institutions. Cash and cash equivalents are defined as short-term, highly liquid investments with a maturity of three months or less at time of purchase that are readily convertible into cash and have insignificant interest rate risk.
Investments in Marketable Securities	We define our marketable securities as fixed income investments which are highly liquid investments that can be readily purchased or sold using established markets. At December 31, 2015, we had marketable securities of $69,496,000 which were comprised primarily of tax exempt municipal bonds. These investments are reported at fair value on our balance sheet. For the year ended December 31, 2015, the accumulated other comprehensive income on our consolidated balance sheet, statements of comprehensive income and stockholders’ equity includes unrealized gains from marketable securities of $543,000 related to marketable securities which are not recognized under the fair value option in accordance with U.S. GAAP. The unrealized gains and losses are recorded net of income taxes. We, in accordance with U.S. GAAP, define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We have not elected the fair value option for our available for sale marketable securities as we believe these assets are more representative of our investing activities and are viewed as non-operating in nature. These assets are available for future needs of the Company to support our current and projected growth, if required. In accordance with U.S. GAAP, our investments in marketable securities are classified within Level 2 of the fair value hierarchy. These investment securities are valued based upon quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Our investment policy is to seek to manage these assets to achieve our goal of preserving principal, maintaining adequate liquidity at all times, and maximizing returns subject to our investment guidelines. Our investment policy limits investment to certain types of instruments issued by institutions primarily with investment grade credit ratings and places restrictions on concentration by type and issuer. We periodically review our investments in marketable securities for other than temporary declines in fair value below the cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Inventories and Supplies	Inventories and supplies include housekeeping, linen and laundry supplies, as well as food provisions and supplies. Inventories and supplies are stated at cost to approximate a first-in, first-out (FIFO) basis. Linen supplies are amortized on a straight-line basis over their estimated useful life of 24 months.
Property and Equipment	Property and equipment are stated at cost. Additions, renewals and improvements are capitalized, while maintenance and repair costs are expensed when incurred. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the respective accounts and any resulting gain or loss is included in income. Depreciation is provided by the straight-line method over the following estimated useful lives: laundry and linen equipment installations — 3 to 7 years; housekeeping, and office furniture and equipment — 3 to 7 years; autos and trucks — 3 years.
Revenue Recognition	Revenues from our service agreements with clients are recognized as services are performed. Revenues are reported net of sales taxes that are collected from customers and remitted to taxing authorities. As a distributor of laundry equipment, we occasionally sell laundry installations to certain clients. The sales in most cases represent the construction and installation of a turn-key operation and are for payment terms ranging from 24 to 60 months. Our accounting policy for these sales is to recognize the gross profit over the life of the payments associated with our financing of the transactions.
Income Taxes	We use the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. We accrue for probable tax obligations as required by facts and circumstances in the various regulatory environments. In addition, deferred tax assets and liabilities are recognized for expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. If appropriate, we would record a valuation allowance to reduce deferred tax assets to an amount for which realization is more likely than not. Deferred tax assets and liabilities are more fully described in subsequent Note 13. In accordance with U.S. GAAP, we account for uncertain income tax positions reflected within our financial statements based on a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.
Earnings per Common Share	Basic earnings per common share are computed by dividing income available to common shareholders by the weighted-average common shares outstanding for the period. Diluted earnings per common share reflect the weighted-average common shares outstanding and dilutive common shares, such as those issuable upon exercise of stock options.
Share-Based Compensation	U.S. GAAP addresses the accounting for share-based compensation, specifically, the measurement and recognition of compensation expense, based on estimated fair values, for all share-based awards made to employees and directors, including stock options and participation in the Company’s employee stock purchase plan. We estimate the fair value of share-based awards on the date of grant using the Black-Scholes option valuation model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense in the Company’s consolidated statements of income over the requisite service periods. We use the straight-line single option method of expensing share-based awards in our consolidated financial statements of income. Because share-based compensation expense is based on awards that are ultimately expected to vest, share-based compensation expense will be reduced to account for estimated forfeitures. Forfeitures are to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
Advertising Costs	Advertising costs are expensed when incurred.
Impairment of Long-Lived Assets	We account for long-lived assets in accordance with the criteria established in U.S. GAAP, which states that the carrying amounts of long-lived assets be periodically reviewed to determine whether current events or circumstances warrant adjustment to such carrying amounts. Any impairment is measured by the amount that the carrying value of such assets exceeds their fair value, primarily based on estimated discounted cash flows. Considerable management judgment is necessary to estimate the fair value of assets. Assets to be disposed of are carried at the lower of their financial statement carrying amount or fair value, less cost to sell.
Acquisitions	We acquire businesses and/or assets that augment and complement our operations from time to time. These acquisitions are accounted for under the purchase method of accounting. The consolidated financial statements include the results of operations from such business combinations as of the date of acquisition.
Identifiable Intangible Assets and Goodwill	Identifiable intangible assets with finite lives are amortized on a straight-line basis over their respective lives. Goodwill represents the excess of costs over the fair value of net assets of the acquired business. We review the carrying values of goodwill at least annually during the fourth quarter of each year to assess impairment because these assets are not amortized. Additionally, we review the carrying value of any intangible asset or goodwill whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. We assess impairment by comparing the fair value of an identifiable intangible asset or reporting unit with its carrying value. Impairments are recorded when incurred.
Treasury Stock	Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Gains or losses on the subsequent reissuance of shares are credited or charged to additional paid in capital.
Reclassification	Certain prior period amounts have been reclassified to conform to current year presentation.
Use of Estimates in Financial Statements	In preparing financial statements in conformity with U.S. GAAP, we make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates are used for, but not limited to, our allowance for doubtful accounts, accrued insurance claims, asset valuations and review for potential impairment, and deferred taxes. The estimates are based upon various factors including current and historical trends, as well as other pertinent industry and regulatory authority information. We regularly evaluate this information to determine if it is necessary to update the basis for our estimates and to compensate for known changes.
Change in Accounting Estimate	In fiscal year 2015, the Company transitioned its workers compensation and certain employee health & welfare insurance programs to HCSG Insurance Corp. ("HCSG Insurance" or the "Captive"), its wholly owned captive insurance subsidiary which was previously providing general liability coverage to the Company. HCSG Insurance was formed in January 2014 to provide the Company with greater flexibility and cost efficiency in meeting its property & casualty and health & welfare needs. In conjunction with the aforementioned insurance programs being administered and provided by the Captive, during the third quarter 2014, management conducted a review of its self-insurance reserves to enhance its self-insurance estimation process.
Concentrations of Credit Risk	The accounting guidance requires the disclosure of significant concentrations of credit risk, regardless of the degree of such risk. Financial instruments, as defined by U.S. GAAP, which potentially subject us to concentrations of credit risk, consist principally of cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. We define our marketable securities as fixed income investments which are highly liquid investments that can be readily purchased or sold using established markets. At December 31, 2015 and 2014, substantially all of our cash and cash equivalents, and marketable securities were held in one large financial institution located in the United States. Our clients are concentrated in the health care industry, primarily providers of long-term care. Many of our clients’ revenues are highly contingent on Medicare, Medicaid and third party payors’ reimbursement funding rates. Congress has enacted a number of major laws during the past decade that have significantly altered, or threatened to alter, overall government reimbursement for nursing home services. These changes and lack of substantive reimbursement funding rate reform legislation, as well as other trends in the long-term care industry have affected and could adversely affect the liquidity of our clients, resulting in their inability to make payments to us on agreed upon payment terms. These factors, in addition to delays in payments from clients, have resulted in, and could continue to result in, significant additional bad debts in the future. State Medicaid programs are experiencing increased demand, and with lower revenues than projected, they have fewer resources to support their Medicaid programs. In addition, comprehensive health care legislation under the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (together, the “Act”) was signed into law in March 2010. The Act will significantly impact the governmental healthcare programs in which our clients participate, and reimbursements received thereunder from governmental or third-party payors. Furthermore, in the coming year and beyond, new proposals or additional changes in existing regulations could be made to the Act which could directly impact the governmental reimbursement programs in which our clients participate. As a result, some state Medicaid programs are reconsidering previously approved increases in nursing home reimbursement or are considering delaying or foregoing those increases. A few states have indicated that it is possible they will run out of cash to pay Medicaid providers, including nursing homes. Any negative changes in our clients’ reimbursements may negatively impact our results of operations. In 2009 and 2010, Federal economic stimulus legislation was enacted to counter the impact of the economic crisis on state budgets. The legislation included the temporary provision of additional federal matching funds to help states maintain their Medicaid programs. This legislation to provide states with an extension of this fiscal relief was extended through June 2011, but at a reduced reimbursement rate. In July 2011, CMS issued a final rule that reduced Medicare payments to nursing centers by 11.1% and changed the reimbursement for the provision of group rehabilitation therapy services to Medicare beneficiaries. This new rule was effective as of October 1, 2011. Even if federal or state legislation is enacted that provides additional funding to Medicaid providers, given the volatility of the economic environment, it is difficult to predict the impact of this legislation on our clients’ liquidity and their ability to make payments to us as agreed. In January 2013, the U.S. Congress enacted the American Taxpayer Relief Act of 2012, which delayed automatic spending cuts, including reduced Medicare payments to plans and providers up to 2%. These discretionary spending caps were originally enacted under provisions in the Budget Control Act of 2011, an initiative to reduce the federal deficit through 2021, also known as “sequestration.” The sequestration went into effect starting March 2013. In December 2013, the U.S. Congress enacted the Bipartisan Budget Act of 2013, which reduces the impact of the sequestration over the next two years. This began in fiscal year 2014 and extended the reduction in Medicare payments to plans and providers for two years from 2021 through 2023.
Significant Clients	We have several clients who each have made a contribution to our total consolidated revenues ranging from 3% to 9% for the year ended December 31, 2015. Although we expect to continue relationships with these clients, there can be no assurance thereof. The loss of such clients, or a significant reduction in the revenues we receive from these clients, would have a material adverse effect on the results of operations of our two operating segments. In addition, if such clients change their respective payment terms it could increase our accounts receivable balance and have a material adverse effect on our cash flows and cash and cash equivalents.
Recent Accounting Pronouncements	In November 2015, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2015-17, Balance Sheet Classification of Deferred Taxes. The amendment in this ASU requires that deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent in a classified statement of financial position. The guidance becomes effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company does not expect the guidance in this ASU to have a material impact on our consolidated financial statements and related disclosures. In September 2015, the Financial Accounting Standards Board issued ASU 2015-16, Business Combinations (Topic 805). The amendments in this ASU require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Additionally, this ASU requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. To simplify the accounting for adjustments made to provisional amounts recognized in a business combination, the amendments in this ASU eliminate the requirement to retrospectively account for those adjustments. This ASU is effective prospectively for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years.The Company does not expect the guidance in this ASU to have a material impact on our consolidated financial statements and related disclosures. In August 2015, the Financial Accounting Standards Board issued ASU 2015-14, Revenue from Contracts with Customer (Topic 606): Deferral of the Effective Date. This ASU defers the effective date of ASU 2014-09, Revenue from Contracts with Customer (Topic 606) for all entities by one year. As a result, all entities will be required to apply the provisions of ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently assessing the adoption date and impact the guidance in this ASU will have, if any, on our consolidated results of operations, cash flows, or financial position. In June 2015, the Financial Accounting Standards Board issued ASU 2015-10, Technical Corrections and Improvements. The amendments in this ASU represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. Additionally, some of the amendments will make the Codification easier to understand and easier to apply by eliminating inconsistencies, providing needed clarifications, and improving the presentation of guidance in the Codification. This ASU is effective for fiscal years and interim periods beginning on or after December 15, 2015, with early adoption permitted. The Company does not expect the guidance in this ASU to have a material impact on our consolidated financial statements and related disclosures.

- Definition

Tabular disclosure of an equity-based arrangement (such as stock or unit options and stock or unit awards) with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain equity-based awards at future dates, sometimes including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares or units issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.
