We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Such forward-looking information is also subject to various risks and uncertainties. Such risks and uncertainties include, but are not limited to, risks arising from our providing services exclusively to the healthcare industry, primarily providers of long-term care; the impact of and future effects of the COVID-19 pandemic or other potential pandemics; having a significant portion of our consolidated revenues contributed by one customer during the six months ended June 30, 2020;2021; credit and collection risks associated with the healthcare industry; our claims experience related to workers’ compensation and general liability insurance (including any litigation claims, enforcement actions, regulatory actions and investigations arising from personal injury and loss of life related to COVID-19); the effects of changes in, or interpretations of laws and regulations governing the healthcare industry, our workforce and services provided, including state and local regulations pertaining to the taxability of our services and other labor-related matters such as minimum wage increases; the Company’s expectations with respect to selling, general, and administrative expense; continued realization of tax benefits arising from our corporate reorganization and self-funded health insurance program; the impact of the Securities and Exchange Commission investigation and related class action lawsuit; risks associated with the reorganization of our corporate structure; and the risk factors described in Part I of our Form 10-K for the fiscal year ended December 31, 20192020 under “Government Regulation of Clients,” “Service Agreements and Collections,” and “Competition,” under Item IA. “Risk Factors” in such Form 10-K and under Item IA. "Risk Factors" in this Form 10-Q.

These factors, in addition to delays in payments from customers and/or customers in bankruptcy, have resulted in, and could continue to result in, significant additional bad debts in the near future. Additionally, our operating results would be adversely affected by continued increases in inflation particularly if unexpected increases in the costs of labor and labor-related costs, materials, supplies and equipment used in performing services (including the impact of potential tariffs and COVID-19) could not be passed on to our customers.

In addition, we believe that to improve our financial performance we must continue to obtain service agreements with new customers, retain and provide new services to existing customers, achieve modest price increases on current service agreements with existing customers and/or maintain internal cost reduction strategies at our various operational levels. Furthermore, we believe that our ability to sustain the internal development of managerial personnel is an important factor impacting future operating results and the successful execution of our projected growth strategies.

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, 20192020 has been derived from the audited financial statements for the year ended December 31, 2019.2020. 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, 2019.2020. The results of operations for the six months ended June 30, 2020interim periods presented are not necessarily indicative of the results that may be expected for any future period.

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.

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 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 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.

Refer to Note 4—Allowance for Doubtful Accounts herein for further information.

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.

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.

Refer to Note 7—Leases herein for further information.

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.

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.

The Company estimates the fair value of share-based awards on the date of grant using the Black-Scholes valuation model for stock options, using a Monte Carlo simulation for performance restricted stock units, and using the share price on the date of grant for restricted stock units and restricteddeferred 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 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.

NaN impairment loss was recognized on the Company's intangible assets or goodwill during the six months ended June 30, 20202021 or 2019.2020.

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.

All of the Company���sThe 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 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 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.
