Accounting Policies [Abstract]
Description of Business and Significant Accounting Policies	Note 1—Description of Business and Significant Accounting Policies Nature of Operations Healthcare Services Group, Inc. (the “Company”) provides management, administrative and operating expertise and services to the housekeeping, laundry, linen, facility maintenance and dietary service departments of the healthcare industry, including nursing homes, retirement complexes, rehabilitation centers and hospitals located throughout the United States. Although the Company does not directly participate in any government reimbursement programs, the Company’s customers receive government reimbursements related to Medicare and Medicaid. Therefore, they are directly affected by any legislation relating to Medicare and Medicaid reimbursement programs. The Company provides services primarily pursuant to full service agreements with its customers. In such agreements, the Company is responsible for the day-to-day management of employees located at the customers’ facilities. The Company also provides services on the basis of management-only agreements for a limited number of customers. The agreements with customers typically provide for a renewable one year service term, cancellable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days. The Company is organized into two reportable segments: housekeeping, laundry, linen and other services (“Housekeeping”), and dietary department services (“Dietary”). Housekeeping consists of managing the customers’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of a customer’s facility, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at a customer facility. Dietary consists of managing the customers’ dietary departments, which are principally responsible for food purchasing, meal preparation and dietitian professional services, which includes the development of menus that meet residents’ dietary needs. Unaudited Interim Financial Data The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, these consolidated financial statements do not include all of the information and footnotes necessary for a complete presentation of financial position, results of operations and cash flows. However, in the Company’s opinion, all adjustments which are of a normal recurring nature and are necessary for a fair presentation have been reflected in these consolidated financial statements. The balance sheet shown in this report as of December 31, 2019 has been derived from the audited financial statements for the year ended December 31, 2019. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations for the six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for any future period. Use of Estimates in Financial Statements In preparing financial statements in conformity with U.S. GAAP, estimates and assumptions are made that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates. Significant estimates are used in determining, but are not limited to, the Company’s allowance for doubtful accounts, accrued insurance claims, valuations, deferred taxes and reviews for potential impairment. The estimates are based upon various factors including current and historical trends, as well as other pertinent industry and regulatory authority information, including the potential future effects of COVID-19. Management regularly evaluates this information to determine if it is necessary to update the basis for its estimates and to adjust for known changes. 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. 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 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. Accounts and Notes Receivable Accounts and notes receivable consist of Housekeeping and Dietary segment trade receivables from contracts with customers. The Company’s payment terms with customers for services provided are defined within each customer’s service agreement. All accounts receivables are considered short term assets as the Company does not grant payment terms greater than one year. Accounts receivable initially are recorded at the transaction amount, and are recorded after the Company has an unconditional right to payment where only the passage of time is required before payment is received. Each reporting period, the Company evaluates the collectability of outstanding receivable balances and records an allowance for doubtful accounts representing an estimate of future expected credit loss. Additions to the allowance for doubtful accounts are made by recording a charge to bad debt expense reported in costs of services provided. Notes receivable are initially recorded when accounts receivable are transferred into a promissory note and are recorded as an alternative to accounts receivable to memorialize an unqualified promise to pay a specific sum, typically with interest, in accordance with a defined payment schedule. The Company’s payment terms with customers on promissory notes can vary based on several factors and the circumstances of each promissory note, however typically promissory notes mature over a 1 to 3 year period. Similar to accounts receivable, each reporting period the Company evaluates the collectability of outstanding notes receivable balances and records an allowance for doubtful accounts representing an estimate of future expected credit loss. Refer to Note 3—Accounts and Notes Receivable herein for further information. Allowance for Doubtful Accounts The guidance under the Financial Accounting Standards Board ("FASB") Accounting Standards Codification subtopic 326 Credit Losses - Measurement of Credit Losses on Financial Instruments ("ASC 326") became effective and was adopted by the Company prospectively as of January 1, 2020. In adopting ASC 326, the Company replaced its previous incurred loss impairment model for estimating credit losses on accounts and notes receivables for its reporting of quarterly and annual financial results with an expected loss model prepared in accordance with ASC 326. While the incurred loss impairment model had the Company recognize credit losses when it was probable that a loss had been incurred, ASC 326 requires the Company to estimate the lifetime expected credit losses on such instruments and to record an allowance to offset the receivables. ASC 326 requires the recognition of credit losses that are expected based on existing accounts and notes receivable as compared to the incurred loss approach. Accordingly, credit losses under ASC 326 generally are recognized earlier in the life cycle of a receivable than under the Company’s previous incurred loss model. Modeling must be prepared after considering historical experience, current conditions, and reasonable and supportable economic forecasts to estimate lifetime expected credit losses. Under the previous incurred loss impairment model, credit losses were recognized when Management determined that it was more likely than not that a loss had been incurred and such loss was estimable. Refer to Note 4—Allowance for Doubtful Accounts herein for further information. The cumulative effect of initially applying the new ASC 326 guidance to the consolidated financial statements on January 1, 2020 was as follows: Consolidated Statement of Financial Position December 31, 2019 Cumulative Impact from Adopting ASC 326 Guidance January 1, 2020 (in thousands) Assets Short-term accounts and notes receivable, less allowance for doubtful accounts $ 340,930 $ (41,100) $ 299,830 Notes receivable – long–term portion, less allowance for doubtful accounts $ 46,992 $ (1,136) $ 45,856 Allowance for doubtful accounts on short-term accounts and notes receivables $ (45,726) $ (41,100) $ (86,826) Allowance for doubtful accounts on long-term notes receivables $ (6,667) $ (1,136) $ (7,803) Deferred income taxes $ 20,364 $ 10,137 $ 30,501 Stockholders’ equity Retained earnings $ 195,455 $ (32,099) $ 163,356 Inventories and Supplies Inventories and supplies include housekeeping, linen and laundry supplies, as well as food provisions and supplies. Non-linen inventories and supplies are stated on a first-in, first-out (FIFO) basis, and reduced as deemed necessary to approximate the lower of cost or net realizable value. Linen supplies are amortized on a straight-line basis over their estimated useful life of 24 months. Revenue Recognition The Company recognizes revenue from contracts with customers when or as the promised goods and services are provided to customers. Revenues are reported net of sales taxes that are collected from customers and remitted to taxing authorities. The guidance under the FASB Accounting Standards Codification subtopic 606 Revenue from Contracts with Customers ("ASC 606") requires the Company to recognize revenue as the promised goods and services within the terms of the Company’s contracts are performed and satisfied. The amount of revenue recognized by the Company is based on the consideration to which the Company is entitled in exchange for providing the contracted goods and services. Refer to Note 2—Revenue herein for further information. Leases The guidance under FASB Accounting Standards Codification subtopic ASC 842 Leases (“ASC 842”) became effective and was adopted by the Company as of January 1, 2019, by applying a modified retrospective transition approach which resulted in the capitalization of the Company’s existing operating leases as of January 1, 2019. As such, the Company records assets and liabilities on the balance sheet to recognize the rights and obligations arising from leasing arrangements with contractual terms greater than 12 months, as permitted by U.S. GAAP. A leasing arrangement includes any contract which entitles the Company to the right of use of an identified tangible asset where there are no restrictions as to the direct of use of the asset, and the Company obtains substantially all of the economic benefits from the right of use. As of June 30, 2020 and December 31, 2019, the Company was only the lessee of operating lease arrangements. Refer to Note 7—Leases herein for further information. Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, income tax expense or benefits are recognized for the amount of taxes payable or refundable for the current period. The Company accrues for probable tax obligations as required, based on facts and circumstances in various regulatory environments. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. When appropriate, valuation allowances are recorded to reduce deferred tax assets to amounts for which realization is more likely than not. Uncertain income tax positions taken or expected to be taken in tax returns are reflected within the Company’s financial statements based on a recognition and measurement process. Earnings per Common Share Basic earnings per common share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is computed using the weighted-average number of common shares outstanding and dilutive common shares, such as those issuable upon exercise of stock options and upon the vesting of restricted stock and restricted stock units. Share-Based Compensation The Company estimates the fair value of share-based awards on the date of grant using the Black-Scholes valuation model for stock options and using the share price on the date of grant for restricted stock and restricted stock units. The value of the award is recognized ratably as an expense in the Company’s Consolidated Statements of Comprehensive Income over the requisite service periods, with adjustments made for forfeitures as they occur. Identifiable Intangible Assets and Goodwill Identifiable intangible assets are amortized on a straight-line basis over their respective lives. Goodwill represents the excess of cost over the fair value of net assets of acquired businesses. Management reviews the carrying value of goodwill annually during the fourth quarter to assess for impairment, or more often if events or circumstances indicate that the carrying value may exceed its estimated fair value. No impairment loss was recognized on the Company's intangible assets or goodwill during the six months ended June 30, 2020 or 2019. Concentrations of Credit Risk The Company’s financial instruments that are subject to credit risk are cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. At June 30, 2020 and December 31, 2019, substantially all of the Company’s cash and cash equivalents and marketable securities were held in one large financial institution located in the United States. The Company’s marketable securities are fixed income investments which are highly liquid and can be readily purchased or sold through established markets. The Company’s customers are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s customers are highly reliant on Medicare, Medicaid and third party payors’ reimbursement funding rates. New legislation or changes in existing regulations could directly impact the governmental reimbursement programs in which the customers participate. As a result, the Company may not realize the full effects of such programs until these laws are fully implemented and governmental agencies issue applicable regulations or guidance.

Revenue from Contract with Customer [Abstract]
Revenue	Note 2—Revenue The Company presents its consolidated revenues disaggregated by reportable segment, as Management evaluates the nature, amount, timing and uncertainty of the Company’s revenues by segment. Refer to Note 13—Segment Information herein as well as the information below regarding the Company’s reportable segments. Housekeeping Housekeeping accounted for $451.9 million and $462.0 million of the Company’s consolidated revenues for the six months ended June 30, 2020 and 2019, respectively, which represented approximately 50.2% and 49.2% of the Company’s revenues in each respective period. The Housekeeping services include managing customers’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of the customers’ facilities, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at the customers’ facilities. Upon beginning service with a customer facility, the Company will typically hire and train the employees previously employed by such facility and assign an on-site manager to supervise and train the front-line personnel and coordinate housekeeping services with other facility support functions in accordance with customer requests. Such management personnel also oversee the execution of various cost and quality-control procedures including continuous training and employee evaluation. Dietary Dietary services accounted for $449.3 million and $476.2 million of the Company’s consolidated revenues for the six months ended June 30, 2020 and 2019, respectively, which represented approximately 49.8% and 50.8% of the Company’s revenues in each respective period. Dietary services consist of managing customers’ dietary departments which are principally responsible for food purchasing, meal preparation and professional dietitian services, which include the development of menus that meet the dietary needs of residents. On-site management is responsible for all daily dietary department activities, with regular support provided by a District Manager specializing in dietary services. The Company also offers clinical consulting services to facilities which if contracted is a service bundled within the monthly service provided to customers. Upon beginning service with a customer facility, the Company will typically hire and train the employees previously employed by such facility and assign an on-site manager to supervise and train the front-line personnel and coordinate dietitian services with other facility support functions in accordance with customer requests. Such management personnel also oversee the execution of various cost and quality-control procedures including continuous training and employee evaluation. Revenue Recognition All of the Company’s revenues are derived from contracts with customers. The Company accounts for revenue from contracts with customers in accordance with ASC 606, and as such, the Company recognizes revenue to depict the transfer of promised goods and services to customers in amounts that reflect the consideration to which the Company is entitled in exchange for those goods and services. The Company’s costs of obtaining contracts are not material. The Company performs services and provides goods in accordance with its contracts with its customers. Such contracts typically provide for a renewable one year service term, cancellable by either party upon 30 to 90 days’ notice, after an initial period of 60 to 120 days. A performance obligation is the unit of account under ASC 606 and is defined as a promise in a contract to transfer a distinct good or service to the customer. The Company’s Housekeeping and Dietary contracts relate to the provision of bundles of goods, services or both, which represent a series of distinct goods and services that are substantially the same and that have the same pattern of transfer to the customer. The Company accounts for the series as a single performance obligation satisfied over time, as the customer simultaneously receives and consumes the benefits of the goods and services provided. Revenue is recognized using the output method, which is based upon the delivery of goods and services to the customers’ facilities. In limited cases, the Company provides goods, services or both, before the execution of a written contract. In these cases, the Company defers the recognition of revenue until a contract is executed. The amount of such deferred revenue was $1.9 million and $0.3 million as of June 30, 2020 and December 31, 2019, respectively. Additionally, substantially all such revenue amounts deferred as of December 31, 2019 were subsequently recognized as revenue during the six months ended June 30, 2020. The transaction price is the amount of consideration to which the Company is entitled in exchange for transferring promised goods or services to its customers. The transaction price does not include taxes assessed or collected. The Company’s contracts detail the fees that the Company charges for the goods and services it provides. For certain contracts which contain a variable component to the transaction price, the Company is required to make estimates of the amount of consideration to which the Company will be entitled, based on variability in resident and patient populations serviced, product usage or quantities consumed. The Company recognizes revenue related to such estimates only when the Company determines that there will not be a significant reversal in the amount of revenue recognized. The Company’s contracts generally do not contain significant financing components, as payment terms are less than one year. The Company allocates the transaction price to each performance obligation, noting that the bundle of goods, services or goods and services provided under each Housekeeping and Dietary contract represents a single performance obligation that is satisfied over time. The Company recognizes the related revenue when it satisfies the performance obligation by transferring a bundle of promised goods, services or both to a customer. Such recognition is on a monthly or weekly basis, as goods are provided and services are performed. In some cases, the Company requires customers to pay in advance for goods and services to be provided. As of June 30, 2020 and December 31, 2019, the value of the contract liabilities associated with customer prepayments was not material. Additionally, substantially all such revenue amounts deferred as of December 31, 2019 were subsequently recognized as revenue during the six months ended June 30, 2020. Transaction Price Allocated to Remaining Performance Obligations The Company recognizes revenue as it satisfies the performance obligations associated with contracts with customers, which due to the nature of the goods and services provided by the Company, are satisfied over time. Contracts may contain transaction prices that are fixed, variable or both. The Company’s contracts with customers typically provide for an initial term of one year, with renewable one year service terms, cancellable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days. At June 30, 2020, the Company had $559.4 million related to performance obligations that were unsatisfied or partially unsatisfied for which the Company expects to recognize revenue. The Company expects to recognize revenue on approximately 20.5% of the remaining performance obligations over the next 12 months, with the balance to be recognized thereafter. These amounts exclude variable consideration primarily related to performance obligations that consists of a series of distinct service periods with revenues based on future performance that cannot be estimated at contract inception. The Company also has elected to apply the practical expedient that permits exclusion of information about the remaining performance obligations with original expected durations of one year or less.

Accounts and Notes Receivable	Note 3—Accounts and Notes Receivable The Company’s accounts and notes receivable balances consisted of the following as of June 30, 2020 and December 31, 2019: June 30, 2020 December 31, 2019 (in thousands) Short-term Accounts and notes receivable $ 370,143 $ 386,656 Allowance for doubtful accounts 1 (74,882) (45,726) Total net short-term accounts and notes receivable $ 295,261 $ 340,930 Long-term Notes receivable $ 50,972 $ 53,659 Allowance for doubtful accounts 1 (9,104) (6,667) Total net long-term notes receivable $ 41,868 $ 46,992 Total net accounts and notes receivable $ 337,129 $ 387,922 1. Effective January 1, 2020, the Company adopted ASC 326 and recorded a one-time adoption adjustment of $42.2 million The Company makes credit decisions on a case-by-case basis after reviewing a number of qualitative and quantitative factors related to the specific customer as well as current industry variables that may impact that customer. There are a variety of factors that impact a customer’s ability to pay in accordance with the Company’s contracts. These factors include, but are not limited to, fluctuating census numbers, litigation costs and the customer’s participation in programs funded by federal and state governmental agencies. Deviations in the timing or amounts of reimbursements under those programs can impact the customer’s cash flows and its ability to make timely payments. However, the customer’s obligation to pay the Company in accordance with the contracts are not contingent upon the customer’s cash flow. Notwithstanding the Company’s efforts to minimize its credit risk exposure, the aforementioned factors, as well as other factors that impact customer cash flows or ability to make timely payments, could have an indirect, yet material adverse effect on the Company’s results of operations and financial condition.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts	6 Months Ended

Receivables [Abstract]
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts On January 1, 2020 (the "adoption date"), the Company replaced its previous incurred loss impairment model for estimating credit losses on accounts and notes receivables with an expected loss model prepared in accordance with ASC 326. While the incurred loss impairment model had the Company recognize credit losses when it was probable that a loss had been incurred, ASC 326 requires the Company to estimate future expected credit losses on such instruments before an impairment may occur. On the adoption date, the Company recorded an initial increase of $42.2 million to the Company's allowance for doubtful accounts, with an offset recorded as an opening adjustment to retained earnings. In making the Company’s credit evaluations, management considers the general collection risk associated with trends in the long-term care industry. The Company establishes credit limits through payment terms with customers, performs ongoing credit evaluations and monitors accounts on an aging schedule basis to minimize the risk of loss. Despite the Company’s efforts to minimize credit risk exposure, customers could be adversely affected if future industry trends, including those related to COVID-19, change in such a manner as to negatively impact their cash flows. The full effects of COVID-19 on the Company’s customers are highly uncertain and cannot be predicted. As a result, the Company’s future collection experience can differ significantly from historical collection trends. If the Company’s customers experience a negative impact on their cash flows, it could have a material adverse effect on the Company’s results of operations and financial condition. The Company evaluates its accounts and notes receivable for expected credit losses quarterly. Accounts receivables are evaluated based on internally developed credit quality indicators derived from the aging of receivables. Notes receivable are evaluated based on internally developed credit quality indicators derived from Management’s assessment of collection risk. The Company manages note receivable portfolios using a two tiered approach by disaggregating standard notes receivables, which are promissory notes in good standing, from those who have been identified by Management as having an elevated credit risk profile due to a trigger event such as bankruptcy. At the end of each period the Company sets a reserve for expected credit losses on standard notes receivable based on the Company’s historical loss rate. Notes receivable with an elevated risk profile, which are from customers who have filed bankruptcy, are subject to collections activity or are slow payers that are experiencing financial difficulties, are aggregated and evaluated to determine the total reserve for the class of receivable. The guidance in ASC 326 permits entities to make an accounting policy election not to measure an estimate for credit losses on accrued interest if those entities write-off accrued interest deemed uncollectible in a timely manner. The Company follows an income recognition policy on all interest earned on notes receivable. Under such policy the Company accounts for all notes receivable on a non-accrual basis and defers the recognition of any interest income until receipt of cash payments. This policy was established, recognizing the environment of the long-term care industry, and not because such notes receivable are necessarily impaired. Accordingly, the Company does not record a credit loss adjustment for accrued interest. For the three and six months ended June 30, 2020, the Company recognized $0.4 million and $1.0 million in interest income from notes receivables. As part of the Company’s adoption of ASC 326, there are additional disclosures required to be made on a class of financing receivable basis. The following table presents the Company’s two tiers of notes receivable further disaggregated by year of origination as of June 30, 2020: Notes Receivable Amortized Cost Basis by Origination Year 2020 2019 2018 2017 2016 Prior Total (in thousands) Notes Receivable Standard notes receivable $ 8,127 $ 13,619 $ 17,669 $ 26,429 $ 275 $ 1,602 $ 67,721 Elevated risk notes receivable $ — $ 604 $ — $ 5,511 $ — $ 2,421 $ 8,536 Current-period gross write-offs $ — $ — $ 411 $ — $ 1,721 $ 36 $ 2,168 Current-period recoveries — — — — — — — Current-period net write-offs $ — $ — $ 411 $ — $ 1,721 $ 36 $ 2,168 The following table provides information as to the status of payment on the Company’s notes receivable which were past due as of June 30, 2020: Age Analysis of Past-Due Notes Receivable as of June 30, 2020 0-90 Days 91 - 180 Days Greater than 181 Days Total (in thousands) Notes Receivable Standard notes receivable $ 638 $ 433 $ 3,075 $ 4,146 Elevated risk notes receivable 1,035 767 5,829 7,631 $ 1,673 $ 1,200 $ 8,904 $ 11,777 The following table provides a summary of the changes in the Company’s allowance for doubtful accounts on a portfolio segment basis for the three and six months ended June 30, 2020: Allowance for doubtful accounts Portfolio Segment: March 31 Write-Offs 1 Bad Debt Expense June 30 (in thousands) Accounts Receivables $ 74,389 $ (9,987) $ 1,897 $ 66,299 Notes Receivables Standard notes receivable $ 11,654 $ (1,721) $ 1,936 $ 11,869 Elevated risk notes receivable 6,237 (447) 28 5,818 $ 17,891 $ (2,168) $ 1,964 $ 17,687 Total accounts and notes receivable $ 92,280 $ (12,155) $ 3,861 $ 83,986 1.

Leases [Abstract]
Leases	Note 7—Leases The Company recognizes ROU assets and lease liabilities (“Lease Liabilities”) for automobiles, office buildings, IT equipment, and small storage units for the temporary storage of operational equipment. The Company’s leases have remaining lease terms ranging from less than 1 year to 10 years, and have extension options ranging from 1 year to 5 years. Most leases include the option to terminate the lease within 1 year. Upon adopting ASC 842, the Company made accounting policy elections using practical expedients offered under the guidance to combine lease and non-lease components within leasing arrangements and to recognize the payments associated with short-term leases in earnings on a straight-line basis over the lease term, with the cost associated with variable lease payments recognized when incurred. These accounting policy elections impact the value of the Company’s ROU Assets and Lease Liabilities. The value of the Company’s ROU Assets is determined as the non-depreciated fair value of its leasing arrangements and is recorded to Property and Equipment, net on the Company’s Consolidated Balance Sheets. The value of the Company’s Lease Liabilities is the present value of fixed lease payments not yet paid, discounted using either the rate implicit in the lease contract if that rate can be determined, or the Company’s incremental borrowing rate ("IBR") and is recorded in Other accrued expenses and Lease liability — long-term portion on the Company’s Consolidated Balance Sheets. Any future lease payments that are not fixed based on the terms of the lease contract, or fluctuate based on a factor other than an index or rate, are considered variable lease payments and are not included in the value of the Company’s ROU Assets or Lease Liabilities. The Company’s IBR is determined as the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Components of lease expense required by ASC 842 are presented below for the three and six months ended June 30, 2020 and 2019.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 9—Fair Value Measurements The Company’s current assets and current liabilities are financial instruments and most of these items (other than marketable securities and inventories) are recorded at cost in the Consolidated Balance Sheets. The estimated fair value of these financial instruments approximates their carrying value due to their short-term nature. The carrying value of the Company’s line of credit represents the outstanding amount of the borrowings, which approximates fair value. The Company’s financial assets that are measured at fair value on a recurring basis are its marketable securities and deferred compensation funding. The recorded values of all of the financial instruments approximate their current fair values because of their nature, stated interest rates and respective maturity dates or durations. The Company’s marketable securities consist of tax-exempt municipal bonds, which are classified as available-for-sale and are reported at fair value. Unrealized gains and losses associated with these investments are included in other comprehensive income (net of tax) within the Consolidated Statements of Comprehensive Income. The fair value of these marketable securities is classified within Level 2 of the fair value hierarchy, as these securities are measured using 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. Such valuations are determined by a third-party pricing service. For the three months ended June 30, 2020 and 2019, the Company recorded unrealized gains of $1.7 million and $0.8 million on marketable securities, respectively. For the six months ended June 30, 2020 and 2019, the Company recorded unrealized gains of $1.1 million and of $2.2 million on marketable securities, respectively. For the three months ended June 30, 2020 and 2019, the Company received total proceeds, less the amount of interest received, of $4.0 million and $3.6 million, respectively, from sales of available-for-sale municipal bonds. For the three months ended June 30, 2020 and 2019, these sales resulted in realized losses of $0.1 million and realized gains of $0.1 million, respectively. For the six months ended June 30, 2020 and 2019, the Company received total proceeds, less the amount of interest received of $5.8 million and $7.1 million, respectively, from sales of available-for-sale municipal bonds. For the six months ended June 30, 2020 and 2019, these sales resulted in realized losses of $0.1 million and realized gains of $0.1 million, respectively, which were recorded in “Other income – Investment and other income, net” in the Consolidated Statements of Comprehensive Income. The basis for the sale of these securities was the specific identification of each bond sold during the period. The investments under the funded deferred compensation plan are accounted for as trading securities and unrealized gains or losses are included in earnings. The fair value of these investments are determined based on quoted market prices (Level 1). For the three months ended June 30, 2020 and 2019, the Company’s recognized unrealized gains of $6.7 million and of $1.6 million, respectively, related to equity securities still held at the respective reporting dates. For the six months ended June 30, 2020 and 2019, the Company's recognized unrealized gains of $1.0 million and of $5.0 million, respectively, related to equity securities still held at the respective reporting dates.

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Note 10—Shared-Based Compensation The components of the Company’s shared-based compensation expense for the six months ended June 30, 2020 and 2019 are as follows: Six Months Ended June 30, 2020 2019 (in thousands) Stock options $ 1,054 $ 1,326 Restricted stock and restricted stock units 2,598 1,998 Employee Stock Purchase Plan 273 335 Total pre-tax share-based compensation expense charged against income 1 $ 3,925 $ 3,659 1. Share-based compensation expense is recorded in cost of services and selling, general and administrative expense in the Company’s Consolidated Statements of Comprehensive Income. At June 30, 2020, the unrecognized compensation cost related to unvested stock options and awards was $20.4 million. The weighted average period over which these awards will vest is approximately 3.1 years. 2020 Omnibus Incentive Plan On May 26, 2020, the Company adopted the 2020 Omnibus Incentive Plan (the "2020 Plan") after approval by the Company's Shareholders at the Annual Meeting of Shareholders. The 2020 Plan provides that current or prospective officers, employees, non-employee directors and advisors can receive share-based awards such as stock options, performance stock units, restricted stock units and other stock awards. The 2020 Plan seeks to encourage profitability and growth of the Company through short-term and long-term incentives that are consistent with the Company's operating objectives. As of June 30, 2020, there were 2.5 million shares of common stock reserved for issuance under the 2020 Plan, of which, all are available for future grant. The amount of shares available for issuance under the 2020 Plan will increase when outstanding awards under the Company's Second Amended and Restated 2012 Equity Incentive Plan (the “2012 Plan”) are subsequently forfeited, terminated, lapsed, or satisfied thereunder in cash or property other than shares. No stock award will have a term in excess of 10 years. The Nominating, Compensation and Stock Option Committee of the Board of Directors is responsible for determining the terms of the grants in accordance with the 2020 Plan. 2012 Equity Incentive Plan The 2012 Plan was replaced by the 2020 Plan upon shareholder approval of the 2020 Plan on May 26, 2020. Accordingly, no new equity awards will be granted under the 2012 Plan. Stock Options A summary of stock options outstanding under as of December 31, 2019 and changes during the six months ended June 30, 2020 is as follows: Stock Options Outstanding Number of Shares Weighted Average Exercise Price (in thousands) December 31, 2019 2,107 $ 32.99 Granted 210 $ 24.43 Exercised (99) $ 17.75 Forfeited (11) $ 37.65 Expired (39) $ 31.97 June 30, 2020 2,168 $ 32.85 The weighted average grant-date fair value of stock options granted during the six months ended June 30, 2020 and 2019 was $4.62 and $8.18 per common share, respectively. The total intrinsic value of stock options exercised during the six months ended June 30, 2020 and 2019 was $0.9 million and $1.5 million, respectively. The fair value of stock option awards granted in 2020 and 2019 was estimated on the date of grant using the Black-Scholes option valuation model with the following assumptions: Six Months Ended June 30, 2020 2019 Risk-free interest rate 1.8 % 2.5 % Weighted average expected life 6.6 years 5.7 years Expected volatility 26.5 % 22.6 % Dividend yield 3.2 % 1.9 % The following table summarizes other information about the stock options at June 30, 2020: June 30, 2020 (amounts in thousands, except per share data) Outstanding: Aggregate intrinsic value $ 1,497 Weighted average remaining contractual life 5.6 years Exercisable: Number of options 1,450 Weighted average exercise price $ 31.08 Aggregate intrinsic value $ 1,491 Weighted average remaining contractual life 4.5 years Restricted Stock Units and Restricted Stock The fair value of outstanding restricted stock units and restricted stock was determined based on the market price of the shares on the date of grant. During the six months ended June 30, 2020, the Company granted 0.3 million restricted stock units with a weighted average grant date fair value of $24.43 per unit. During the six months ended June 30, 2019, the Company granted 0.2 million restricted stock units with a weighted average grant date fair value of $40.49 per unit. During the six months ended June 30, 2020 and 2019, the Company did not grant any restricted stock. A summary of the outstanding restricted stock units and restricted stock as of December 31, 2019 and changes during the six months ended June 30, 2020 is as follows: Restricted Stock Units and Restricted Stock Number Weighted Average Grant Date Fair Value (in thousands) December 31, 2019 362 $ 43.24 Granted 307 $ 24.43 Vested (93) $ 42.30 Forfeited (10) $ 32.69 June 30, 2020 566 $ 33.37 Employee Stock Purchase Plan The Company’s Employee Stock Purchase Plan ("ESPP") is currently available through 2021 to all eligible employees. All full-time and part-time employees who work an average of 20 hours per week and have completed two years of continuous service with the Company are eligible to participate. Annual offerings commence and terminate on the respective year’s first and last calendar day. Under the ESPP, the Company is authorized to issue up to 4.1 million shares of its common stock to its employees. Pursuant to such authorization, there are 2.1 million shares available for future grant at June 30, 2020. The expense associated with the options granted under the ESPP during the six months ended June 30, 2020 and 2019 was estimated on the date of grant using the Black-Scholes option valuation model with the following assumptions: Six Months Ended June 30, 2020 2019 Risk-free interest rate 1.6% 2.6% Weighted average expected life (years) 1.0 1.0 Expected volatility 42.0% 30.8% Dividend yield 3.3% 1.9% Deferred Compensation Plan The Company offers a Supplemental Executive Retirement Plan (“SERP”) for executives and certain key employees. The SERP allows participants to defer a portion of their earned income on a pre-tax basis and as of the last day of each plan year, each participant will be credited with a match of a portion of their deferral in the form of the Company’s common stock based on the then-current market value. Under the SERP, the Company is authorized to issue 1.0 million shares of its common stock to its employees. Pursuant to such authorization, the Company has 0.4 million shares available for future grant at June 30, 2020. At the time of issuance, such shares are accounted for at cost as treasury stock. The following table summarizes information about the SERP during the six months ended June 30, 2020 and 2019: Six Months Ended June 30, 2020 2019 (in thousands) SERP expense 1 $ 298 $ 346 Unrealized gain recorded in SERP liability account $ 763 $ 4,939 1. Both the SERP match and the deferrals are included in the selling, general and administrative caption in the Consolidated Statements of Comprehensive Income.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Note 12—Income Taxes The Company’s annual effective tax rate is impacted by the tax effects of option exercises and vested awards, which are treated as discrete items in the reporting period in which they occur, and therefore cannot be considered in the calculation of the estimated annual effective tax rate. The impact on the Company’s income tax provision through the six months ended June 30, 2020 for such discrete items was not material. Differences between the effective tax rate and the applicable U.S. federal statutory rate arise primarily from the effect of state and local income taxes, share-based compensation and tax credits available to the Company. The actual 2020 effective tax rate will likely vary from the estimate depending on the actual operating income earned with availability of tax credits and the exercise of stock options and vesting of share-based awards. The Company’s estimate for the 2020 effective tax rate has not been adjusted for any impacts related to COVID-19. The Company accounts for income taxes using the asset and liability method, which results in recognizing income tax expense based on the amount of income taxes payable or refundable for the current year. Additionally, the Company regularly evaluates the tax positions taken or expected to be taken resulting from financial statement recognition of certain items. Based on the evaluation, there are no significant uncertain tax positions requiring recognition in the Company’s financial statements. The evaluation was performed for the tax years ended December 31, 2016 through 2019 (with regard to U.S. federal income tax returns) and December 31, 2015 through 2019 (with regard to various state and local income tax returns), the tax years which remain subject to examination by major tax jurisdictions as of June 30, 2020.

Segment Information

Segment Reporting [Abstract]
Segment Information	Note 13—Segment Information The Company manages and evaluates its operations in two reportable segments: Housekeeping (housekeeping, laundry, linen and other services) and Dietary (dietary department services). Although both segments serve the same customer base and share many operational similarities, they are managed separately due to distinct differences in the type of services provided, as well as the specialized expertise required of the professional management personnel responsible for delivering each segment’s services. Such services are rendered pursuant to discrete contracts, specific to each reportable segment. The Company’s accounting policies for the segments are generally the same as described in the Company’s significant accounting policies. Differences between the reportable segments’ operating results and other disclosed data and the information in the consolidated financial statements relate primarily to corporate level transactions and recording of transactions at the reportable segment level using 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 in the consolidated financial statements. In addition, most corporate expenses such as corporate salary and benefit costs, certain legal costs, debt expense, information technology costs, depreciation, amortization of finite-lived intangible assets, share based compensation costs and other corporate-specific costs, are not fully allocated to the operating segments. There are also allocations for workers’ compensation and general liability expense within the operating segments that differ from the actual expense recorded by the Company under U.S. GAAP. Segment amounts disclosed are prior to elimination entries made in consolidation.

Earnings Per Common Share

Earnings Per Common Share	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Common Share	Note 14—Earnings Per Common Share Basic and diluted earnings per common share are computed by dividing net income by the weighted-average number of basic and diluted common shares outstanding, respectively. The weighted-average number of diluted common shares includes the impact of dilutive securities, including outstanding stock options and unvested restricted stock and restricted stock units. The table below reconciles the weighted-average basic and diluted common shares outstanding: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 (in thousands) Weighted average number of common shares outstanding - basic 74,695 74,352 74,676 74,327 Effect of dilutive securities 1 66 267 88 342 Weighted average number of common shares outstanding - diluted 74,761 74,619 74,764 74,669 1. Certain outstanding equity awards are anti-dilutive and therefore were excluded from the calculation of the weighted average number of diluted common shares outstanding. Anti-dilutive outstanding equity awards under share-based compensation plans were as follows: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 (in thousands) Anti-dilutive 2,102 1,536 2,096 1,455

Commitments and Contingencies Disclosure [Abstract]
Other Contingencies	Note 15—Other Contingencies Line of Credit At June 30, 2020, the Company had a $475 million bank line of credit on which to draw for general corporate purposes. Amounts drawn under the line of credit are payable upon demand and generally bear interest at a float rate, based on the Company’s leverage ratio, and starting at LIBOR plus 115 basis points (or if LIBOR becomes unavailable, the higher of the Overnight Bank Funding Rate, plus 50 basis points and the Prime Rate). As of June 30, 2020 there were no borrowings under the line of credit. As of December 31, 2019 there were $10.0 million in borrowings under the line of credit. The line of credit requires the Company to satisfy two financial covenants, with which the Company is in compliance as of June 30, 2020. The line of credit expires on December 21, 2023. At June 30, 2020, the Company also had outstanding $64.9 million in irrevocable standby letters of credit, which relate to payment obligations under the Company’s insurance programs. In connection with the issuance of the letters of credit, the amount available under the line of credit was reduced by $64.9 million to $410.1 million at June 30, 2020. The letters of credit expire on January 2, 2021. Besides the $64.9 million letters of credit there are no other restrictions as to the amount which the Company can draw upon the $475 million line of credit. Tax Jurisdictions and Matters The Company provides services throughout the continental United States and is subject to numerous state and local taxing jurisdictions. In the ordinary course of business, a jurisdiction may contest the Company’s reporting positions with respect to the application of its tax code to the Company’s services, which could result in additional tax liabilities. The Company has tax matters with various taxing authorities. Because of the uncertainties related to both the probable outcomes and amount of probable assessments due, the Company is unable to make a reasonable estimate of a liability. The Company does not expect the resolution of any of these matters, taken individually or in the aggregate, to have a material adverse effect on the consolidated financial position or results of operations based on the Company’s best estimate of the outcomes of such matters. Legal Proceedings The Company is 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 the Company becomes aware of such claims and legal actions, the Company records accruals for any exposures that are probable and estimable. If adverse outcomes of such claims and legal actions are reasonably possible, Management assesses materiality and provides financial disclosure, as appropriate. As previously disclosed, the Securities and Exchange Commission (“SEC”) is conducting an investigation into the Company’s earnings per share (“EPS”) calculation practices. Following receipt of a letter from the SEC in November 2017 regarding its inquiry into those practices followed by a subpoena in March 2018, the Company authorized its outside counsel to conduct an internal investigation, under the direction of the Company’s Audit Committee, into matters related to the SEC subpoena. This investigation was completed in March 2019 and the Company continues to cooperate with the SEC’s investigation and document requests. On March 22, 2019, a putative shareholder class action lawsuit was filed against the Company and its Chief Executive Officer in the U.S. District Court for the Eastern District of Pennsylvania. The initial complaint, which was filed by a plaintiff purportedly on behalf of all purchasers of the Company’s securities between April 11, 2017 and March 4, 2019 (the "Class Period"), alleges violations of the federal securities laws in connection with the matters related to the Company’s EPS calculation practices. On September 17, 2019, the complaint was amended to, among other things, extend the Class Period to cover the period between April 8, 2014 and March 4, 2019, and to name additional individuals affiliated with the Company as defendants. The lead plaintiff seeks unspecified monetary damages and other relief on behalf of the plaintiff class. While the Company is vigorously defending against all litigation claims asserted, this litigation—along with the ongoing SEC investigation—could result in substantial costs to the Company and a diversion of the Company’s management’s attention and resources, which could harm its business. In addition, the uncertainty of the pending lawsuit or potential filing of additional lawsuits could lead to more volatility and a reduction in the Company’s stock price. At this time the Company is unable to reasonably estimate possible losses or form a judgment that an unfavorable outcome is either probable or remote. It is not currently possible to assess whether or not the outcome of these proceedings may have a material adverse effect on the Company. Government Regulations

Accounting Policies [Abstract]
Nature of Operations	Healthcare Services Group, Inc. (the “Company”) provides management, administrative and operating expertise and services to the housekeeping, laundry, linen, facility maintenance and dietary service departments of the healthcare industry, including nursing homes, retirement complexes, rehabilitation centers and hospitals located throughout the United States. Although the Company does not directly participate in any government reimbursement programs, the Company’s customers receive government reimbursements related to Medicare and Medicaid. Therefore, they are directly affected by any legislation relating to Medicare and Medicaid reimbursement programs. The Company provides services primarily pursuant to full service agreements with its customers. In such agreements, the Company is responsible for the day-to-day management of employees located at the customers’ facilities. The Company also provides services on the basis of management-only agreements for a limited number of customers. The agreements with customers typically provide for a renewable one year service term, cancellable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days. The Company is organized into two reportable segments: housekeeping, laundry, linen and other services (“Housekeeping”), and dietary department services (“Dietary”). Housekeeping consists of managing the customers’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of a customer’s facility, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at a customer facility. Dietary consists of managing the customers’ dietary departments, which are principally responsible for food purchasing, meal preparation and dietitian professional services, which includes the development of menus that meet residents’ dietary needs.
Unaudited Interim Financial Data	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, these consolidated financial statements do not include all of the information and footnotes necessary for a complete presentation of financial position, results of operations and cash flows. However, in the Company’s opinion, all adjustments which are of a normal recurring nature and are necessary for a fair presentation have been reflected in these consolidated financial statements. The balance sheet shown in this report as of December 31, 2019 has been derived from the audited financial statements for the year ended December 31, 2019. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations for the six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for any future period.
Use of Estimates in Financial Statements	In preparing financial statements in conformity with U.S. GAAP, estimates and assumptions are made that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates. Significant estimates are used in determining, but are not limited to, the Company’s allowance for doubtful accounts, accrued insurance claims, valuations, deferred taxes and reviews for potential impairment. The estimates are based upon various factors including current and historical trends, as well as other pertinent industry and regulatory authority information, including the potential future effects of COVID-19. Management regularly evaluates this information to determine if it is necessary to update the basis for its estimates and to adjust for known changes.
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.
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 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.
Accounts and Notes Receivable	Accounts and notes receivable consist of Housekeeping and Dietary segment trade receivables from contracts with customers. The Company’s payment terms with customers for services provided are defined within each customer’s service agreement. All accounts receivables are considered short term assets as the Company does not grant payment terms greater than one year. Accounts receivable initially are recorded at the transaction amount, and are recorded after the Company has an unconditional right to payment where only the passage of time is required before payment is received. Each reporting period, the Company evaluates the collectability of outstanding receivable balances and records an allowance for doubtful accounts representing an estimate of future expected credit loss. Additions to the allowance for doubtful accounts are made by recording a charge to bad debt expense reported in costs of services provided. Notes receivable are initially recorded when accounts receivable are transferred into a promissory note and are recorded as an alternative to accounts receivable to memorialize an unqualified promise to pay a specific sum, typically with interest, in accordance with a defined payment schedule. The Company’s payment terms with customers on promissory notes can vary based on several factors and the circumstances of each promissory note, however typically promissory notes mature over a 1 to 3 year period. Similar to accounts receivable, each reporting period the Company evaluates the collectability of outstanding notes receivable balances and records an allowance for doubtful accounts representing an estimate of future expected credit loss.
Recent Accounting Pronouncements	The guidance under the Financial Accounting Standards Board ("FASB") Accounting Standards Codification subtopic 326 Credit Losses - Measurement of Credit Losses on Financial Instruments ("ASC 326") became effective and was adopted by the Company prospectively as of January 1, 2020. In adopting ASC 326, the Company replaced its previous incurred loss impairment model for estimating credit losses on accounts and notes receivables for its reporting of quarterly and annual financial results with an expected loss model prepared in accordance with ASC 326. While the incurred loss impairment model had the Company recognize credit losses when it was probable that a loss had been incurred, ASC 326 requires the Company to estimate the lifetime expected credit losses on such instruments and to record an allowance to offset the receivables. ASC 326 requires the recognition of credit losses that are expected based on existing accounts and notes receivable as compared to the incurred loss approach. Accordingly, credit losses under ASC 326 generally are recognized earlier in the life cycle of a receivable than under the Company’s previous incurred loss model. Modeling must be prepared after considering historical experience, current conditions, and reasonable and supportable economic forecasts to estimate lifetime expected credit losses. Under the previous incurred loss impairment model, credit losses were recognized when Management determined that it was more likely than not that a loss had been incurred and such loss was estimable. Refer to Note 4—Allowance for Doubtful Accounts herein for further information. The cumulative effect of initially applying the new ASC 326 guidance to the consolidated financial statements on January 1, 2020 was as follows: Consolidated Statement of Financial Position December 31, 2019 Cumulative Impact from Adopting ASC 326 Guidance January 1, 2020 (in thousands) Assets Short-term accounts and notes receivable, less allowance for doubtful accounts $ 340,930 $ (41,100) $ 299,830 Notes receivable – long–term portion, less allowance for doubtful accounts $ 46,992 $ (1,136) $ 45,856 Allowance for doubtful accounts on short-term accounts and notes receivables $ (45,726) $ (41,100) $ (86,826) Allowance for doubtful accounts on long-term notes receivables $ (6,667) $ (1,136) $ (7,803) Deferred income taxes $ 20,364 $ 10,137 $ 30,501 Stockholders’ equity Retained earnings $ 195,455 $ (32,099) $ 163,356
Inventories and Supplies	Inventories and supplies include housekeeping, linen and laundry supplies, as well as food provisions and supplies. Non-linen inventories and supplies are stated on a first-in, first-out (FIFO) basis, and reduced as deemed necessary to approximate the lower of cost or net realizable value. Linen supplies are amortized on a straight-line basis over their estimated useful life of 24 months.
Revenue Recognition	The Company recognizes revenue from contracts with customers when or as the promised goods and services are provided to customers. Revenues are reported net of sales taxes that are collected from customers and remitted to taxing authorities. The guidance under the FASB Accounting Standards Codification subtopic 606 Revenue from Contracts with Customers
Leases	The guidance under FASB Accounting Standards Codification subtopic ASC 842 Leases (“ASC 842”) became effective and was adopted by the Company as of January 1, 2019, by applying a modified retrospective transition approach which resulted in the capitalization of the Company’s existing operating leases as of January 1, 2019. As such, the Company records assets and liabilities on the balance sheet to recognize the rights and obligations arising from leasing arrangements with contractual terms greater than 12 months, as permitted by U.S. GAAP. A leasing arrangement includes any contract which entitles the Company to the right of use of an identified tangible asset where there are no restrictions as to the direct of use of the asset, and the Company obtains substantially all of the economic benefits from the right of use. As of June 30, 2020 and December 31, 2019, the Company was only the lessee of operating lease arrangements.
Income Taxes	The Company uses the asset and liability method of accounting for income taxes. Under this method, income tax expense or benefits are recognized for the amount of taxes payable or refundable for the current period. The Company accrues for probable tax obligations as required, based on facts and circumstances in various regulatory environments. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. When appropriate, valuation allowances are recorded to reduce deferred tax assets to amounts for which realization is more likely than not. Uncertain income tax positions taken or expected to be taken in tax returns are reflected within the Company’s financial statements based on a recognition and measurement process.
Earnings per Common Share	Basic earnings per common share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is computed using the weighted-average number of common shares outstanding and dilutive common shares, such as those issuable upon exercise of stock options and upon the vesting of restricted stock and restricted stock units.
Share-Based Compensation	The Company estimates the fair value of share-based awards on the date of grant using the Black-Scholes valuation model for stock options and using the share price on the date of grant for restricted stock and restricted stock units. The value of the award is recognized ratably as an expense in the Company’s Consolidated Statements of Comprehensive Income over the requisite service periods, with adjustments made for forfeitures as they occur.
Identifiable Intangible Assets and Goodwill	Identifiable intangible assets are amortized on a straight-line basis over their respective lives. Goodwill represents the excess of cost over the fair value of net assets of acquired businesses. Management reviews the carrying value of goodwill annually during the fourth quarter to assess for impairment, or more often if events or circumstances indicate that the carrying value may exceed its estimated fair value.
Concentrations of Credit Risk	The Company’s financial instruments that are subject to credit risk are cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. At June 30, 2020 and December 31, 2019, substantially all of the Company’s cash and cash equivalents and marketable securities were held in one large financial institution located in the United States. The Company’s marketable securities are fixed income investments which are highly liquid and can be readily purchased or sold through established markets. The Company’s customers are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s customers are highly reliant on Medicare, Medicaid and third party payors’ reimbursement funding rates. New legislation or changes in existing regulations could directly impact the governmental reimbursement programs in which the customers participate. As a result, the Company may not realize the full effects of such programs until these laws are fully implemented and governmental agencies issue applicable regulations or guidance.
Segments	The Company’s accounting policies for the segments are generally the same as described in the Company’s significant accounting policies. Differences between the reportable segments’ operating results and other disclosed data and the information in the consolidated financial statements relate primarily to corporate level transactions and recording of transactions at the reportable segment level using 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 in the consolidated financial statements. In addition, most corporate expenses such as corporate salary and benefit costs, certain legal costs, debt expense, information technology costs, depreciation, amortization of finite-lived intangible assets, share based compensation costs and other corporate-specific costs, are not fully allocated to the operating segments. There are also allocations for workers’ compensation and general liability expense within the operating segments that differ from the actual expense recorded by the Company under U.S. GAAP. Segment amounts disclosed are prior to elimination entries made in consolidation.

Description of timing			The Company’s contracts with customers typically provide for an initial term of one year, with renewable one year service terms, cancellable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days.At June 30, 2020, the Company had $559.4 million related to performance obligations that were unsatisfied or partially unsatisfied for which the Company expects to recognize revenue. The Company expects to recognize revenue on approximately 20.5% of the remaining performance obligations over the next 12 months, with the balance to be recognized thereafter. These amounts exclude variable consideration primarily related to performance obligations that consists of a series of distinct service periods with revenues based on future performance that cannot be estimated at contract inception. The Company also has elected to apply the practical expedient that permits exclusion of information about the remaining performance obligations with original expected durations of one year or less.
