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 managers and hourly 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 90-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. We began the Dietary operations in 1997. As of December 31, 2012, we operate two wholly-owned subsidiaries, Huntingdon Holdings, Inc. (“Huntingdon”) and Healthcare Staff Leasing Solutions, LLC (“Staff Leasing”). Huntingdon invests our cash and cash equivalents as well as manages our portfolio of marketable securities. Staff Leasing is an entity formed in 2011 to offer professional employer organization (“PEO”) services to potential clients in the health care industry. As of December 31, 2012, we have PEO service contracts in two states. 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 consists 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 $1,639,000 and $1,855,000 at December 31, 2012 and 2011, respectively, have been discounted to their present value and are reported at such values of $1,620,000 and $1,828,000 at December 31, 2012 and 2011, 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, 2012, we had marketable securities of $21,322,000 which were comprised primarily of tax exempt municipal bonds. These investments are reported at fair value on our balance sheet. Unrealized losses of $82,000 at December 31, 2012 were recorded in our consolidated statement of comprehensive income for the year then ended for investments recorded under the fair value option. For the year ended December 31, 2012, the accumulated other comprehensive income on our consolidated balance sheet and stockholders’ equity includes unrealized gains from marketable securities of $127,000 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). Effective January 1, 2008, we elected the fair value option for certain of our marketable securities purchased since such adoption. Management initially elected the fair value option for certain of our marketable securities because we viewed such investment securities as highly liquid and available to be drawn upon for working capital purposes making them similar to cash and cash equivalents. Accordingly, we record net unrealized gain or loss in the other income, investment and interest caption in our consolidated statements of income for such investments. We have not elected the fair value option for marketable securities acquired after December 31, 2009. Although these assets continue to be highly liquid and available, we believe these assets are more representative of our investing activities. 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 maturities and 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, 2012, 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 in the years ended December 31, 2012, 2011 and 2010 was $2,947,000, $2,416,000 and $1,864,000, respectively. Revenue Recognition Revenues from our service agreements with clients are recognized as services are performed. 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 2012, 2011 and 2010 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 Notes to the Consolidated Financial Statements. 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, 2012, 2011 and 2010. 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 for the years ended December 31, 2012, 2011 or 2010. 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. Three-for-Two Stock Split On October 12, 2010, our Board of Directors declared a three-for-two stock split in the form of a 50% common stock dividend which was paid on November 12, 2010 to shareholders of record at the close of business on November 8, 2010. All share and per common share information for all periods presented have been adjusted to reflect the three-for-two stock split. 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 revenues and 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. 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, 2012 and 2011, substantially all of our cash and cash equivalents, and marketable securities were held in one large financial institution located in the United States, in excess of regulatory insured amounts. 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. As a result of the current economic crisis, many states have significant budget deficits. 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. 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 Centers for Medicare and Medicaid Services (“CMS”) and other agencies issue applicable regulations or guidance. 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 the year 2021, also known as “sequestration.” The sequestration is set to go into effect starting March 2013, absent further action by Congress and the Administration. Significant Clients We have several clients who each who have made a contribution to our total consolidated revenues ranging from 3% to 7% for the year ended December 31, 2012. 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 May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. This ASU clarifies the FASB's intent regarding application of existing fair value measurements and disclosures, revises certain measurement and disclosure requirements that change or modify a principle to achieve convergence with International Financial Reporting Standards and expands the information required to be disclosed with respect to fair value measurements categorized in Level 3 fair value measurements. The ASU is effective for fiscal years and interim periods beginning on or after December 15, 2011, with early adoption prohibited. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position. In June 2011, the Financial Accounting Standards Board (“FASB”) issued ASU 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. This ASU allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. This ASU eliminates the option to report other comprehensive income and its components in the statement of changes in stockholders' equity. While this ASU changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. This ASU is effective for fiscal years and interim periods beginning after December 15, 2011. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position. In September 2011, the FASB issued ASU 2011-08, Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment. This ASU allows an entity to assess qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether it is necessary to perform the two-step goodwill impairment test required under current accounting standards. This ASU is effective for fiscal years beginning after December 15, 2011, with early adoption permitted. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position. In December 2011, the FASB issued ASU 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. This ASU is a deferral of the effective date pertaining to reclassification adjustments out of accumulated other comprehensive income in ASU 2011-05. The FASB is going to reassess the costs and benefits of those provisions in ASU 2011-05 related to reclassifications out of accumulated other comprehensive income. Due to the time required to properly make such a reassessment and to evaluate alternative presentation formats, the FASB decided that it is necessary to reinstate the requirements for the presentation of reclassifications out of accumulated other comprehensive income that were in place before the issuance of ASU 2011-05. This ASU is effective for fiscal years and interim periods beginning after December 15, 2011. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position. In July 2012, the FASB issued ASU 2012-02, Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. This ASU allows an entity to make a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired. If an entity concludes, based on an evaluation of all relevant qualitative factors, that it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it will not be required to perform the quantitative impairment test for that asset. The objective of this ASU is to reduce the cost and complexity of performing an impairment test for indefinite-lived intangible assets by simplifying how an entity tests those assets for impairment and to improve consistency in impairment testing guidance among long-lived asset categories. This ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position.

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 managers and hourly 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 90-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. We began the Dietary operations in 1997.

As of December 31, 2012, we operate two wholly-owned subsidiaries, Huntingdon Holdings, Inc. (“Huntingdon”) and Healthcare Staff Leasing Solutions, LLC (“Staff Leasing”). Huntingdon invests our cash and cash equivalents as well as manages our portfolio of marketable securities. Staff Leasing is an entity formed in 2011 to offer professional employer organization (“PEO”) services to potential clients in the health care industry. As of December 31, 2012, we have PEO service contracts in two states.

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 consists 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 $1,639,000 and $1,855,000 at December 31, 2012 and 2011, respectively, have been discounted to their present value and are reported at such values of $1,620,000 and $1,828,000 at December 31, 2012 and 2011, 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, 2012, we had marketable securities of $21,322,000 which were comprised primarily of tax exempt municipal bonds. These investments are reported at fair value on our balance sheet. Unrealized losses of $82,000 at December 31, 2012 were recorded in our consolidated statement of comprehensive income for the year then ended for investments recorded under the fair value option. For the year ended December 31, 2012, the accumulated other comprehensive income on our consolidated balance sheet and stockholders’ equity includes unrealized gains from marketable securities of $127,000 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). Effective January 1, 2008, we elected the fair value option for certain of our marketable securities purchased since such adoption. Management initially elected the fair value option for certain of our marketable securities because we viewed such investment securities as highly liquid and available to be drawn upon for working capital purposes making them similar to cash and cash equivalents. Accordingly, we record net unrealized gain or loss in the other income, investment and interest caption in our consolidated statements of income for such investments. We have not elected the fair value option for marketable securities acquired after December 31, 2009. Although these assets continue to be highly liquid and available, we believe these assets are more representative of our investing activities. 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 maturities and 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, 2012, 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 in the years ended December 31, 2012, 2011 and 2010 was $2,947,000, $2,416,000 and $1,864,000, respectively.

Revenue Recognition

Revenues from our service agreements with clients are recognized as services are performed.

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 2012, 2011 and 2010 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 Notes to the Consolidated Financial Statements.

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, 2012, 2011 and 2010.

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 for the years ended December 31, 2012, 2011 or 2010.

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.

Three-for-Two Stock Split

On October 12, 2010, our Board of Directors declared a three-for-two stock split in the form of a 50% common stock dividend which was paid on November 12, 2010 to shareholders of record at the close of business on November 8, 2010. All share and per common share information for all periods presented have been adjusted to reflect the three-for-two stock split.

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 revenues and 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.

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, 2012 and 2011, substantially all of our cash and cash equivalents, and marketable securities were held in one large financial institution located in the United States, in excess of regulatory insured amounts.

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.

As a result of the current economic crisis, many states have significant budget deficits. 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. 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 Centers for Medicare and Medicaid Services (“CMS”) and other agencies issue applicable regulations or guidance.

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 the year 2021, also known as “sequestration.” The sequestration is set to go into effect starting March 2013, absent further action by Congress and the Administration.

Significant Clients

We have several clients who each who have made a contribution to our total consolidated revenues ranging from 3% to 7% for the year ended December 31, 2012. 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 May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. This ASU clarifies the FASB's intent regarding application of existing fair value measurements and disclosures, revises certain measurement and disclosure requirements that change or modify a principle to achieve convergence with International Financial Reporting Standards and expands the information required to be disclosed with respect to fair value measurements categorized in Level 3 fair value measurements. The ASU is effective for fiscal years and interim periods beginning on or after December 15, 2011, with early adoption prohibited. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position.

In June 2011, the Financial Accounting Standards Board (“FASB”) issued ASU 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. This ASU allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. This ASU eliminates the option to report other comprehensive income and its components in the statement of changes in stockholders' equity. While this ASU changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. This ASU is effective for fiscal years and interim periods beginning after December 15, 2011. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position.

In September 2011, the FASB issued ASU 2011-08, Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment. This ASU allows an entity to assess qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether it is necessary to perform the two-step goodwill impairment test required under current accounting standards. This ASU is effective for fiscal years beginning after December 15, 2011, with early adoption permitted. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position.

In December 2011, the FASB issued ASU 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. This ASU is a deferral of the effective date pertaining to reclassification adjustments out of accumulated other comprehensive income in ASU 2011-05. The FASB is going to reassess the costs and benefits of those provisions in ASU 2011-05 related to reclassifications out of accumulated other comprehensive income. Due to the time required to properly make such a reassessment and to evaluate alternative presentation formats, the FASB decided that it is necessary to reinstate the requirements for the presentation of reclassifications out of accumulated other comprehensive income that were in place before the issuance of ASU 2011-05. This ASU is effective for fiscal years and interim periods beginning after December 15, 2011. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position.

In July 2012, the FASB issued ASU 2012-02, Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. This ASU allows an entity to make a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired. If an entity concludes, based on an evaluation of all relevant qualitative factors, that it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it will not be required to perform the quantitative impairment test for that asset. The objective of this ASU is to reduce the cost and complexity of performing an impairment test for indefinite-lived intangible assets by simplifying how an entity tests those assets for impairment and to improve consistency in impairment testing guidance among long-lived asset categories. This ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this standard in 2012 did not have a material impact on the Company's consolidated results of operations, cash flows, or financial position.
