CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This report and documents incorporated by reference into itmay contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which are not historical facts but rather are based on current expectations, estimates and projections about our business and industry, and our beliefs and assumptions. Words such as “believes,” “anticipates,” “plans,” “expects,” “will,” “goal,” and similar expressions are intended to identify forward-looking statements. The inclusion of forward-looking statements should not be regarded as a representation by us that any of our plans will be achieved. 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; having a significant portion of our consolidated revenues contributed by one customer during the nine months ended September 30, 2018; credit and collection risks associated with the healthcare industry; our claims experience related to workers’ compensation and general liability insurance; 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; risks associated with the reorganization of our corporate structure; realization of our expectations regarding the impact of the Tax Cuts and Jobs Act on our financial results; and the risk factors described in Part I of our Form 10-K for the fiscal year ended December 31, 2017 under “Government Regulation of Clients,” “Competition” and “Service Agreements and Collections,” and under Item IA. “Risk Factors” in such Form 10-K.

These factors, in addition to delays in payments from clients and/or clients in bankruptcy or clients with which we are in litigation to collect payment, 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 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) could not be passed on to our clients.

In addition, we believe that to improve our financial performance we must continue to obtain service agreements with new clients, retain and provide new services to existing clients, achieve modest price increases on current service agreements with existing clients and 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.

Notes to Consolidated Financial Statements

(Unaudited)

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 clients 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 clients. In such agreements, the Company is responsible for the day-to-day management of employees located at the clients’ facilities. The Company also provides services on the basis of management-only agreements for a limited number of clients. The agreements with clients typically provide for renewable one year service terms, cancelable 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 clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of a client’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 client facility.

Dietary consists of managing the clients’ 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, 2017 has been derived from, and does not include, all of the disclosures contained in the financial statements for the year ended December 31, 2017. 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, 2017. The results of operations for the nine months ended September 30, 2018 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. 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.

8

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 receivables from contracts with customers. Accounts receivable initially are recorded at the transaction amount, and 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 probable losses. 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. Notes receivable 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.

Refer to Note 3— Accounts and Notes Receivable herein for further information.

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 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.

Revenue Recognition

The Company recognizes revenue from service agreements 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification subtopic 606 Revenue from Contracts with Customers (“ASC 606”) became effective and was adopted by the Company as of January 1, 2018, by applying the modified retrospective method for contracts that were not completed as of January 1, 2018. The standard 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 which the Company recognizes is based on the consideration which the Company expects to be entitled to in exchange for contracted promised goods and services. The adoption of this standard did not have a material impact to the Company's accounting for revenue earned relating to the Housekeeping and Dietary segments. The Company also did not recognize an opening adjustment to retained earnings as a result of the adoption of the standard. See Note 2—Revenue herein for additional revenue disclosure that is being presented as a result of the newly adopted standard.

Prior period amounts were not adjusted and continue to be reported in accordance with previous guidance.

Income Taxes

The Company uses 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 period. The Company accrues for probable tax obligations as required by facts and circumstances in 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 basis 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.

9

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 calculated 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 at least annually during the fourth quarter of each year 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 nine months ended September 30, 2018.

Concentrations of Credit Risk

The financial instruments that are subject to concentrations of credit risk are cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. The Company’s marketable securities are fixed income investments which are highly liquid and can be readily purchased or sold through established markets. At September 30, 2018 and December 31, 2017, 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 clients are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s clients 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 clients participate. As a result, the Company may not know the full effects of such programs until these laws are fully implemented and governmental agencies issue applicable regulations or guidance.

Recent Accounting Pronouncements

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize assets and liabilities on their balance sheet related to the rights and obligations created by most leases, while continuing to recognize expenses on their income statements over the lease term. It will also require disclosures designed to give financial statement users information regarding the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted for all entities. The Company will adopt ASU 2016–02 as of January 1, 2019 and will apply certain practical expedients offered in the guidance, such as those that state that the Company need not reassess whether expired or existing contracts contain leases, reevaluate the classification of expired or existing leases, or reassess initial direct costs for existing leases. Management has substantially completed the process of identifying existing lease contracts and is currently performing detailed evaluations of the leases under the new accounting requirements. The Company believes the most significant changes to the financial statements relate to the recognition of right–of–use assets and offsetting lease liabilities in the consolidated balance sheet for operating leases. The actual impact on the consolidated balance sheet will be contingent upon the Company's population of operating leases at adoption, however Management does not expect the standard to have a material impact on cash flows or results of operations.

In January 2017, the FASB issued Accounting Standards Update 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 no longer requires companies to perform a hypothetical purchase price allocation to measure impairment, eliminating step 2 of the goodwill impairment test. Instead, impairment will be measured using the difference of the carrying amount to the fair value of goodwill on a reporting unit basis. The guidance is effective for annual reporting periods beginning after December 15, 2019, but early adoption is permitted. The Company has elected to early adopt ASU 2017-04 for the annual evaluation which will be performed during the fourth quarter of 2018.

Note 2—Revenue

The Company disaggregates its consolidated revenues by reportable segment, as Management evaluates the nature, amount, timing and uncertainty of the Company’s revenues by segment. Refer to Note 12—Segment Information herein as well as the information below regarding the Company’s reportable segments.

Housekeeping

Housekeeping accounted for approximately 48.5%, or $734.2 million, and 53.7%, or $733.7 million, of the Company’s consolidated revenues for the nine months ended September 30, 2018 and 2017, respectively. The services provided under this segment include managing clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of the clients’ facilities, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at the clients’ facilities. Upon beginning service with a client 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 client requests. Such management personnel also oversee the execution of various cost and quality control procedures including continuous training and employee evaluation, and on-site testing for infection control.

Dietary

Dietary services represented approximately 51.5%, or $778.2 million, and 46.3%, or $633.0 million, of the Company’s consolidated revenues for the nine months ended September 30, 2018 and 2017, respectively. Dietary services consist of managing clients’ 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 being provided by a District Manager specializing in dietary services, as well as a registered dietitian. The Company also offers clinical consulting services to facilities which if contracted is a service bundled within the monthly service provided to clients. Upon beginning service with a client 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 client requests. Such management personnel also oversee the execution of various cost- and quality-control procedures including continuous training and employee evaluation.

Revenue Recognition

Substantially 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 expects to be 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 contracts with its customers. Such contracts typically provide for a renewable one year service term, cancelable by either party upon 30 to 90 days' notice, after an initial period of 60 to 120 days. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account under ASC 606. 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 and that are substantially the same and that have the same pattern of transfer to the customer. Accordingly, 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 clients’ 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 not material as of September 30, 2018 and December 31, 2017.

The transaction price is the amount of consideration to which the Company expects to be 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 Management 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 the contracts contain payment terms that are less than one year.

11

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 September 30, 2018 and December 31, 2017, the value of the associated contract liabilities was not material.

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 significant majority of the Company’s contracts with customers have an initial term of one year or less, with renewable one year service terms, cancelable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days. For the purpose of disclosing the transaction price allocated to remaining performance obligations, the Company elected to apply practical expedients available under the guidance in ASC 606 to exclude from the calculation future revenues expected for the performance of services under contracts with variable consideration that are for a term of one year or less. Although only a small portion of the Company’s contracts have an original expected duration that exceeds one year, the Company has historically had, and expects to continue to have, favorable client retention rates. As of September 30, 2018, the revenue expected to be recognized with the fixed transaction price associated with the remaining performance obligations under the Company’s existing contracts with a term greater than one year is $67.9 million for the remainder of 2018, $271.7 million for 2019, $271.7 million for 2020, $271.7 million for 2021, $271.7 million for 2022 and $339.6 million thereafter.

Note 3— Accounts and Notes Receivable

The Company’s accounts and notes receivable balances consisted of the following as of September 30, 2018 and December 31, 2017:

	September 30, 2018			December 31, 2017
	(in thousands)
Short-term
Accounts and notes receivable	$	392,114		$	390,705
Allowance for doubtful accounts	(38,630		)	(11,985		)
Total net short-term accounts and notes receivable	353,484			378,720
Long-term
Notes receivable	55,906			15,476
Allowance for doubtful accounts	(10,000		)	—
Total net long-term notes receivable	45,906			15,476
Total net accounts and notes receivable	$	399,390		$	394,196

The Company makes credit decisions on a case–by–case basis after reviewing a number of qualitative and quantitative factors related to the specific client as well as current industry variables that may impact that client. There are a variety of factors that impact a client’s ability to pay in accordance with the Company’s service agreements. These factors include, but are not limited to, fluctuating census numbers, litigation costs and the client’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 client’s cash flows and their ability to make timely payments. However, the client's obligation to pay the Company in accordance with the service agreements are not contingent upon the client’s cash flows. Notwithstanding the Company’s efforts to minimize its credit risk exposure, the aforementioned factors, as well as other factors that impact client 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.

12

The Company’s net current accounts and notes receivable balance decreased from December 31, 2017. Fluctuations in net accounts and notes receivable are generally attributable to a variety of factors including, but not limited to, the timing of cash receipts from customers and the inception, transition or termination of client relationships. However, the Company offset its accounts and notes receivable with an increased allowance for doubtful accounts in the first quarter 2018 related primarily to corporate restructurings of two privately-held, multi-state operators that occurred during the first quarter 2018. In addition, the Company converted approximately $24.8 million of accounts receivable to long-term notes receivable, due to the achievement of key operational and financial milestones related to the 2017 dining and nutrition expansion with Genesis HealthCare. Also, in the third quarter of 2018 the Company finalized an agreement for a long-term promissory note receivable related to the previously mentioned corporate restructurings from the first quarter 2018. The promissory note receivable was $10.0 million, net of reserve, and was finalized during the three months ended September 30, 2018. Prior to the promissory note being finalized, the corresponding accounts receivable balance was net of a $10.0 million allowance for doubtful accounts reserve which was originally recorded during the first quarter 2018. As a result of the promissory note, the Company reclassified the reserve balance to an allowance for doubtful accounts on the Company’s long-term notes receivable.

The Company deploys significant resources and has invested in tools and processes to optimize Management’s credit and collections efforts. When appropriate, the Company utilizes interest-bearing promissory notes as an alternative to accounts receivable to enhance the collectability of amounts due, by instituting a definitive repayment plan and providing a means by which to further evidence the amounts owed. As of September 30, 2018 and December 31, 2017, the Company had $66.5 million and $36.6 million, net of reserves, respectively, of such promissory notes outstanding. In addition, the Company may assist clients who are adjusting to changes in their cash flows by amending the Company’s agreements from full-service to management-only arrangements, or by modifying contractual payment terms to accommodate clients who have in good faith established clearly-defined plans for addressing cash flow issues. These efforts are intended to minimize the Company’s collections risk while maintaining relationships with the clients.

Note 4— Allowance for Doubtful Accounts

The allowance for doubtful accounts is established when the Company determines that it is probable that receivables have been impaired and the Company can reasonably estimate the amount of the losses. The related provision for bad debts is charged to costs of services provided in the Company’s Consolidated Statements of Comprehensive Income. The allowance for doubtful accounts is evaluated based on the Company’s ongoing review of accounts and notes receivable and is inherently subjective as it requires estimates susceptible to significant revision as more information becomes available.

The Company has had varying collections experience with respect to its accounts and notes receivable. The Company has sometimes extended the period of payment for certain clients beyond contractual terms. In order to provide for such collection issues and the general risk associated with the granting of credit terms, the Company recorded bad debt provisions (in Allowance for Doubtful Accounts) of $42.4 million and $4.0 million for the nine months ended September 30, 2018 and 2017, respectively. The increase in the provision for bad debts period-over-period is primarily related to corporate restructurings of two privately-held, multi-state operators that occurred during the first quarter 2018.

In making the Company’s credit evaluations, in addition to analyzing and anticipating, where possible, the specific cases described above, Management considers the general collection risk associated with trends in the long-term care industry. The Company establishes credit limits, performs ongoing credit evaluations and monitors accounts to minimize the risk of loss. Despite the Company’s efforts to minimize credit risk exposure, clients could be adversely affected if future industry trends change in such a manner as to negatively impact their cash flows. If the Company’s clients 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.

Note 7—Other Intangible Assets

The Company’s other intangible assets consist of customer relationships which were obtained through acquisitions and are recorded at their fair values at the date of acquisition. Intangible assets with determinable lives are amortized on a straight-line basis over their estimated useful lives. The customer relationships have a weighted-average amortization period of approximately 10 years.

The following table sets forth the estimated amortization expense for intangibles subject to amortization for the remainder of 2018, the following five fiscal years and thereafter:

Note 8—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 September 30, 2018 and 2017, the Company recorded unrealized losses of $0.5 million and unrealized gains of $0.1 million on marketable securities, respectively. For the nine months ended September 30, 2018 and 2017, the Company recorded unrealized losses of $1.5 million and unrealized gains of $1.2 million on marketable securities, respectively.

For the three months ended September 30, 2018 and 2017, the Company received total proceeds, less the amount of interest received, of $2.9 million and $5.7 million, respectively, from sales of available-for-sale municipal bonds. For the three months ended September 30, 2018 and 2017, these sales resulted in realized losses of less than $0.1 million and realized gains of $0.2 million, respectively. For the nine months ended September 30, 2018 and 2017, the Company received total proceeds, less the amount of interest received, of $8.7 million and $20.4 million, respectively, from sales of available-for-sale municipal bonds. For the nine months ended September 30, 2018 and 2017, these sales resulted in realized losses of $0.2 million and less than $0.1 million, respectively, which were recorded in “Other income, net – Investment and interest” 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.

2012 Equity Incentive Plan

The Company’s Second Amended and Restated 2012 Equity Incentive Plan (the “Plan”) provides that current or prospective officers, employees, non-employee directors and advisors can receive share-based awards such as stock options, restricted stock, restricted stock units and other stock awards. The Plan seeks to promote the highest level of performance by providing an economic interest in the long-term success of the Company.

As of September 30, 2018, 2.9 million shares of common stock were reserved for issuance under the Plan, including 0.5 million shares available for future grant. No stock award will have a term in excess of ten years. All awards granted under the Plan become vested and exercisable ratably over a five year period on each yearly anniversary of the grant date.

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 2.3 million shares available for future grant at September 30, 2018.

The expense associated with the options granted under the ESPP during the nine months ended September 30, 2018 and 2017 was estimated on the date of grant using the Black-Scholes option valuation model with the following assumptions:

	Nine Months Ended September 30,
	2018	2017

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 September 30, 2018. At the time of issuance, such shares are accounted for at cost as treasury stock.

Note 11— Income Taxes

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Act”), which significantly changed U.S. tax law. The Act lowered the Company’s U.S. statutory federal income tax rate from 35% to 21% effective January 1, 2018. Year to date, the Company has recognized a provision for income taxes of $12.9 million.

The 2018 estimated annual effective tax rate is expected to be approximately 21% to 23%. The actual annual effective tax rate will be impacted by the tax effects of option exercises or 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 for the nine months ended September 30, 2018 for such discrete items was approximately $1.2 million.

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 2018 effective tax rate will likely vary from the estimate depending on the availability of tax credits and the exercise of stock options and vesting of share-based awards.

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, 2013 through 2017 (with regard to U.S. federal income tax returns) and December 31, 2012 through 2017 (with regard to various state and local income tax returns), the tax years which remain subject to examination by major tax jurisdictions as of September 30, 2018.

The Company may from time to time be assessed interest or penalties by taxing jurisdictions, although any such assessments historically have been minimal and immaterial to its financial results. When the Company has received an assessment for interest and/or penalties, it will be classified in the financial statements as selling, general and administrative expense. In addition, any interest or penalties relating to recognized uncertain tax positions would also be recorded in selling, general and administrative expense.

Note 12—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 client 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 service agreements, 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, bad debt expense, information technology costs, depreciation, amortization of finite-lived intangible assets, share based compensation costs and other corporate-specific costs, are not 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.

It is also inclusive of charges recorded to provision to bad debt during the first quarter of 2018 as a result of restructuring events primarily from two customers that occurred during the nine months ended September 30, 2018. No such charges were recorded for the three months ended September 30, 2018.

Note 13—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 September 30,		Nine Months Ended September 30,
	2018	2017	2018	2017
	(in thousands)
Weighted average number of common shares outstanding - basic	74,019	73,461	73,972	73,272
Effect of dilutive securities (1)	560	1,077	626	980
Weighted average number of common shares outstanding - diluted	74,579	74,538	74,598	74,252

⁽¹⁾  Certain outstanding equity awards are anti-dilutive and were therefore excluded from the calculation of the weighted average number of diluted common shares outstanding. During the three and nine months ended September 30, 2018, stock options to purchase 0.6 million shares having a weighted average exercise price of $42.79 and $42.70 per share, respectively, were excluded. During the three months ended September 30, 2017, there were no anti-dilutive stock options, and during the nine months ended September 30, 2017, stock options to purchase 0.5 million shares having a weighted average exercise price of $39.38 per share were excluded. During the three and nine months ended September 30, 2018, 0.1 million restricted stock units were excluded. During the three and nine months ended September 30, 2017, there were no anti-dilutive restricted stock units.

Note 14— Other Contingencies

Line of Credit

At September 30, 2018, the Company had a $300 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 LIBOR plus 75 basis points. At September 30, 2018, there were $10.0 million in borrowings under the line of credit. The line of credit requires the Company to satisfy one financial covenant, with which the Company is in compliance as of September 30, 2018 and expects to remain in compliance. The line of credit expires on December 18, 2018, and although no assurances can be provided that the Company will renew the line of credit or secure other financing, the Company expects the line of credit to be renewed prior to expiration, or substituted with another form of financing.

At September 30, 2018, the Company also had outstanding $65.9 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$65.9 million to $224.2 million at September 30, 2018.

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. The Company believes it is not a party to, nor are any of its properties the subject of, any pending legal proceeding or governmental examination that would have a material adverse effect on the Company’s consolidated financial condition or liquidity.

22

Government Regulations

The Company’s clients are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s clients are highly reliant on Medicare, Medicaid and third party payors’ reimbursement funding rates. New legislation or additional changes in existing regulations could directly impact the governmental reimbursement programs in which the clients participate. The full effect of any such programs would not be realized until these laws are fully implemented and government agencies issue applicable regulations or guidance.

Note 15—Subsequent Events

The Company evaluated all subsequent events through the filing date of this Form 10-Q. There were no events or transactions occurring during this subsequent reporting period which require recognition or additional disclosure in these financial statements.

Item 2.  Management’s Discussion and Analysisof Financial Condition and Results ofOperations

Results of Operations

The following discussion is intended to provide the reader with information that will be helpful in understanding our financial statements, including the changes in certain key items when comparing financial statements period to period. We also intend to provide the primary factors that accounted for those changes, as well as a summary of how certain accounting principles affect our financial statements. In addition, we are providing information about the financial results of our two operating segments to further assist in understanding how these segments and their results affect our consolidated results of operations. This discussion should be read in conjunction with our financial statements as of September 30, 2018 and December 31, 2017 and the notes accompanying those financial statements.

Overview

We provide management, administrative and operating expertise and services to the housekeeping, laundry, linen, facility maintenance and dietary service departments of healthcare facilities, including nursing homes, retirement complexes, rehabilitation centers and hospitals located throughout the United States. We believe we are the largest provider of housekeeping and laundry management services to the long-term care industry in the nation, rendering such services to over 3,500 facilities throughout the continental United States as of September 30, 2018.

We provide services primarily pursuant to full service agreements with our clients. Under such agreements, we are responsible for the day-to-day management of the employees located at our clients’ facilities, as well as for the provision of certain supplies. We also provide services on the basis of management-only agreements for a limited number of clients. Under a management-only agreement, we provide management and supervisory services while the client facility retains payroll responsibility for the non-supervisory staff. Our agreements with clients typically provide for a renewable one year service term, cancelable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days.

We are organized into two reportable segments: housekeeping, laundry, linen and other services (“Housekeeping”), and dietary department services (“Dietary”).

Housekeeping consists of managing our clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of the clients’ facilities, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at the clients’ facilities. Upon beginning service with a client facility, we 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 client requests. Such management personnel also oversee the execution of various cost and quality control procedures including continuous training and employee evaluation, and on-site testing for infection control.

Dietary consists of managing our clients’ 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 being provided by a District Manager specializing in dietary services, as well as a registered dietitian. We also offer clinical consulting services our dietary clients, which may be provided as a stand-alone service, or bundled with other dietary department services. Upon beginning service with a client facility, we 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 client requests. Such management personnel also oversee the execution of various cost- and quality-control procedures including continuous training and employee evaluation.

At September 30, 2018, Housekeeping services were provided at essentially all of our approximately 3,500 client facilities, generating approximately 48.5% or $734.2 million of our total revenues for the nine months ended September 30, 2018. Dietary services were provided to over 1,500 client facilities at September 30, 2018 and contributed approximately 51.5% or $778.2 million of our total revenues for the nine months ended September 30, 2018.

Subject to the factors noted in the Cautionary Statement Regarding Forward Looking Statements included in this Quarterly Report on Form 10-Q, and although there can be no assurance thereof, we expect our consolidated revenues for the remainder of 2018 to continue to grow. We expect that Dietary revenues will continue to grow as a percentage of consolidated revenue and such growth is expected to come from extending our Dietary department service offerings to our current Housekeeping client base. Growth in Housekeeping is expected to primarily come from obtaining new clients.

Three Months Ended September 30, 2018 and 2017

The following table summarizes the income statement key components that we use to evaluate our financial performance on a consolidated and reportable segment basis, for the three months ended September 30, 2018 and 2017. The differences between the reportable segments’ operating results and other disclosed data and our consolidated financial results relate primarily to corporate level transactions and adjustments related to transactions recorded at the reportable segment level which use methods other than generally accepted accounting principles.

Housekeeping revenues represented approximately 47.8% of consolidated revenues for the three months ended September 30, 2018. Dietary revenues represented approximately 52.2% of consolidated revenues for the three months ended September 30, 2018.

The following table sets forth the ratio which certain items bear to consolidated revenues:

Revenues

Consolidated

Consolidated revenues increased 3.2% to $506.9 million for the three months ended September 30, 2018 compared to $491.4 million for the corresponding period in 2017, as a result of the factors discussed below under Reportable Segments.

During the quarter ending September 30, 2018 we adjusted our contractual relationships with two regional customers as well as a number of independent facilities to reflect a reduced provision of services. Our expectation is the contract changes will impact housekeeping segment revenues by approximately $10 million per quarter, with half of the decrease being reflected in the quarter ending September 30, 2018, and will favorably impact future margins.

Reportable Segments

Housekeeping’s segment revenues decreased 2.1% compared to the corresponding period in 2017. This was partially driven from two regional customers as well as a number of independent facilities adjusting their contractual relationships with the Company during the quarter ending September 30, 2018. Dietary’s 8.5% net growth in reportable segment revenues resulted primarily from providing these services to existing Housekeeping clients.

Costs of Services Provided

Consolidated

Consolidated costs of services provided increased2.9% to $439.2 million for the three months ended September 30, 2018 compared to $426.9 million for the three months ended September 30, 2017, which is primarily related to our 3.2% growth in consolidated revenues for the same period. As a percentage of consolidated revenues, costs of services provided decreased to 86.6% in the three months ended September 30, 2018 from 86.9% in the corresponding period in 2017.

Certain significant components within our costs of services provided are subject to fluctuation with changes in our business and client base. Labor and other labor-related costs, dining and housekeeping supplies, and self-insurance costs account for most of our consolidated costs of services provided. See the discussion under Reportable Segments below for additional information on the changes in the components of costs of services provided.

The following table provides a comparison of key indicators we consider when managing the consolidated costs of services provided:

	Three Months Ended September 30,
Costs of Services Provided - Key Indicators as a % of Consolidated Revenue	2018	2017	Change
Bad debt provision	0.6%	0.4%	0.2%
Self-insurance costs	2.7%	2.6%	0.1%

The increase in the bad debt provision is related to our assessment of the collectability of our accounts and notes receivable.

Reportable Segments

Costs of services provided for Housekeeping, as a percentage of Housekeeping revenues, decreased to 88.8% for the three months ended September 30, 2018 from 89.1% in the corresponding period in 2017. Costs of services provided for Dietary, as a percentage of Dietary revenues, decreased to 93.8% for the three months ended September 30, 2018 from 95.3% in the corresponding period in 2017.

The following table provides a comparison of the key indicators we consider when managing costs of services provided at the segment level, as a percentage of the respective segment’s revenues:

	Three Months Ended September 30,
Costs of Services Provided - Key Indicators as a % of Segment Revenue	2018	2017	Change
Housekeeping labor and other labor-related costs	78.4%	79.6%	(1.2)%
Housekeeping supplies	7.8%	7.9%	(0.1)%
Dietary labor and other labor-related costs	56.3%	58.0%	(1.7)%
Dietary supplies	34.4%	35.4%	(1.0)%

Variations within these key indicators relate to the provision of services at new facilities and changes in the mix of clients for whom we provide supplies or do not provide supplies. Management focuses on building efficiencies and managing labor and other costs at the facility level, as well as managing supply chain costs, for new and existing facilities.

26

Consolidated Selling, General and Administrative Expense

Excluding the change in the deferred compensation plan described below, consolidated selling, general and administrative expense increased$3.3 million or 10.2% during the three months ended September 30, 2018 compared to the corresponding period in 2017. Selling, general and administrative expense was reported at 7.2% of revenues, but after adjusting for the $1.6 million change in deferred compensation, actual expense was 6.9% of consolidated revenues. During the quarter, selling, general and administrative expense was also impacted by a $3 million, state-specific sales tax settlement. The settlement, related to certain of the Company’s historical client service billings, resolved the outstanding sales tax considerations and accordingly, will have no impact on future earnings per share. Going forward, the Company expects selling, general and administrative expense to approximate 6.75% of consolidated revenues, with the on-going opportunity to garner additional efficiencies.

Included in selling, general and administrative expense are gains and losses associated with changes in the value of investments under the deferred compensation plan. These investments represent the amounts held on behalf of the participating employees and changes in the value of these investments affect the amount of our deferred compensation liability. Gains on the plan investments during the three months ended September 30, 2018 and 2017increased our total selling, general and administrative expense for these periods.

The table below summarizes the changes in these components of selling, general and administrative expense:

	Three Months Ended September 30,
	2018		2017		$ Change		% Change
	(in thousands)
Selling, general and administrative expense excluding change in deferred compensation liability	$	35,139	$	31,878	$	3,261	10.2	%
Gain on deferred compensation plan investments	1,574		1,062		512		48.2	%
Selling, general and administrative expense	$	36,713	$	32,940	$	3,773	11.5	%

Consolidated Investment and Interest Income, net

Investment and interest income increased40.9% for the three months ended September 30, 2018 compared to the corresponding 2017 period, primarily due to favorable market fluctuations in the value of our trading security investments representing the funding for our deferred compensation plan. Realized gains and losses on our available-for-sale municipal bonds also impacted consolidated investment income.

Consolidated Income Taxes

During the three months ended September 30, 2018, the Company recognized a provision for income taxes of $6.9 million versus a provision for income taxes of $9.5 million for the same period in 2017. On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act, which lowered our U.S. statutory federal income tax rate from 35% to 21% effective January 1, 2018.

Our 2018 estimated annual effective tax rate is expected to be approximately 21% to 23%. The actual annual effective tax rate will be impacted by the tax effects of option exercises or 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 income tax recognized from such discrete items for the three months ended September 30, 2018 was immaterial.

27

Nine Months Ended September 30, 2018 and 2017

The following table summarizes the income statement key components that we use to evaluate our financial performance on a consolidated and reportable segment basis, for the nine months ended September 30, 2018 and 2017. The differences between the reportable segments’ operating results and other disclosed data and our consolidated financial results relate primarily to corporate level transactions and adjustments related to transactions recorded at the reportable segment level which use methods other than generally accepted accounting principles.

Revenues

Consolidated

Consolidated revenues increased10.7% to $1.5 billion for the nine months ended September 30, 2018 compared to $1.4 billion for the corresponding period in 2017 as a result of the factors discussed below under Reportable Segments.

During the quarter ending September 30, 2018 we adjusted our contractual relationships with two regional customers as well as a number of independent facilities to reflect a reduced provision of services. Our expectation is the contract changes will impact housekeeping segment revenues by approximately $10 million per quarter, with half of the decrease being reflected in the quarter ending September 30, 2018, and will favorably impact future margins.

Reportable Segments

Housekeeping’s 0.1% net growth in reportable segment revenues resulted from service agreements entered into with new clients. This growth was also offset from two regional customers as well as a number of independent facilities adjusting their contractual relationships with the Company. Dietary’s 22.9% net growth in reportable segment revenues resulted primarily from providing these services to existing Housekeeping clients.

Costs of services provided

Consolidated

Consolidated costs of services increased14.1% to $1.3 billion for the nine months ended September 30, 2018 compared to $1.2 billion for the nine months ended September 30, 2017, which is primarily related to our 10.7% growth in consolidated revenues for the same period. As a percentage of consolidated revenues, costs of services increasedto 89.0% in the nine months ended September 30, 2018 from 86.3% in the corresponding period in 2017.

Certain significant components within our costs of services provided are subject to fluctuation with changes in our business and client base. Labor and other labor-related costs, dining and housekeeping supplies, and self-insurance costs account for most of our consolidated costs of services provided. See the discussion under Reportable Segments below for additional information on the changes in the components of costs of services provided.

The following table provides a comparison of key indicators we consider when managing the consolidated costs of services provided:

	Nine Months Ended September 30,
Costs of Services Provided - Key Indicators as a % of Consolidated Revenue	2018	2017	Change
Bad debt provision	2.8%	0.3%	2.5%
Self-insurance costs	2.6%	2.7%	(0.1)%

The increase in the bad debt provision is related to the first quarter 2018 increase to the accounts receivable allowance, which was primarily related to the corporate restructuring of two privately-held multi-state operators.

Reportable Segments

Costs of services provided for Housekeeping, as a percentage of Housekeeping revenues, decreased to 88.4% for the nine months ended September 30, 2018 from 90.3% in the corresponding period in 2017. Costs of services provided for Dietary, as a percentage of Dietary revenues, decreased to 94.0% for the nine months ended September 30, 2018 from 94.5% in the corresponding period in 2017.

The following table provides a comparison of the key indicators we consider when managing costs of services provided at the segment level, as a percentage of the respective segment’s revenues:

	Nine Months Ended September 30,
Costs of Services Provided - Key Indicators as a % of Segment Revenue	2018	2017	Change
Housekeeping labor and other labor-related costs	78.4%	80.0%	(1.6)%
Housekeeping supplies	7.9%	8.0%	(0.1)%
Dietary labor and other labor-related costs	56.8%	55.9%	0.9%
Dietary supplies	34.7%	36.6%	(1.9)%

29

Variations within these key indicators relate to the provision of services at new facilities and changes in the mix of clients for whom we provide supplies or do not provide supplies. Management focuses on building efficiencies and managing labor and other costs at the facility level, as well as managing supply chain costs, for new and existing facilities.

Selling, General and Administrative Expense

Excluding the change in the deferred compensation plan described below, consolidated selling, general and administrative expense increased$12.2 million or 13.5% during the nine months ended September 30, 2018 compared to the corresponding period in 2017, related primarily to our overall growth. Selling, general and administrative expense, excluding the change in the deferred compensation plan, increased to6.7% of consolidated revenues for the nine months ended September 30, 2018 compared to 6.6% in the corresponding period in 2017.

Included in selling, general and administrative expense are gains and losses associated with changes in the value of investments under the deferred compensation plan. These investments represent the amounts held on behalf of the participating employees and changes in the value of these investments affect the amount of our deferred compensation liability. Gains on the plan investments during the nine months ended September 30, 2018 and 2017increased our total selling, general and administrative expense for these periods.

The table below summarizes the changes in these components of selling, general and administrative expense:

	Nine Months Ended September 30,
	2018		2017		$ Change			% Change
	(in thousands)
Selling, general and administrative expense excluding change in deferred compensation liability	$	101,916	$	89,766	$	12,150		13.5	%
Gain on deferred compensation plan investments	2,692		3,375		(683		)	(20.2	)%
Selling, general and administrative expense	$	104,608	$	93,141	$	11,467		12.3	%

Consolidated Investment and Interest Income, net

Investment and interest income decreased15.5% for the nine months ended September 30, 2018 compared to the corresponding 2017 period, primarily due to higher interest costs associated with our short–term borrowings. Partially offsetting the decrease in investment and interest income, net was higher interest received on our outstanding notes receivable.

Consolidated Income Taxes

For the nine months ended September 30, 2018, the Company recognized a provision for income taxes of $12.9 million versus a provision for income taxes of $30.2 million for the same period in 2017. On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act, which lowered our U.S. statutory federal income tax rate from 35% to 21% effective January 1, 2018.

The 2018 estimated annual effective tax rate is expected to be approximately 21% to 23%. The actual annual effective tax rate will be impacted by the tax effects of option exercises or 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 of such discrete items was a $1.2 million income tax benefit for the nine months ended September 30, 2018.

Liquidity and Capital Resources

Cash generated through operations is our primary source of liquidity. At September 30, 2018, we had cash, cash equivalents and marketable securities of $89.9 million and working capital of $341.8 million, compared to December 31, 2017 cash, cash equivalents and marketable securities of $82.8 million and working capital of $343.2 million. The decrease in working capital was driven by a decrease in the Company’s net receivables, primarily as a result of the increase in the accounts receivable allowance as of September 30, 2018 compared with December 31, 2017. As of September 30, 2018, we had an unused line of credit of $224.2 million. Our current ratio was 3.1 to 1 at September 30, 2018 versus 2.9 to 1 at December 31, 2017.

For the nine months ended September 30, 2018 and 2017, our cash flows were as follows:

	Nine Months Ended September 30,
	2018			2017
	(in thousands)
Net cash provided by operating activities	$	74,509		$	3,122
Net cash used in investing activities	$	(7,621	)	$	(10,077	)
Net cash used in financing activities	$	(61,248	)	$	(5,893	)

Operating Activities

Our primary sources of cash from operating activities are the revenues generated from our Housekeeping and Dietary services. Our primary uses of cash from operating activities are the funding of our payroll and other personnel-related costs, as well as the costs of supplies used in providing our services. The timing of cash receipts and cash payments are the primary drivers of the period-over-period changes in net cash provided by operating activities.

Investing Activities

Our principal uses of cash for investing activities are the purchases of marketable securities and capital expenditures such as those for housekeeping and food service equipment, computer software and equipment, and furniture and fixtures (see “Capital Expenditures” below for additional information). Such uses of cash are partially offset by proceeds from sales of marketable securities.

Our investments in marketable securities are primarily comprised of tax-exempt municipal bonds and are intended to achieve our goal of preserving principal, maintaining adequate liquidity 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 ratings and places restrictions on concentration by type and issuer.

Financing Activities

The primary use of cash for financing activities is the payment of dividends. We have paid regular quarterly cash dividends since the second quarter of 2003. During 2018, we paid regular quarterly cash dividends to shareholders totaling $42.7 million as follows:

	Quarter Ended
	March 31, 2018		June 30, 2018		September 30, 2018
	(amounts in thousands, except per share data)
Cash dividend paid per common share	$	0.19125	$	0.19250	$	0.19375
Total cash dividends paid	$	14,149	$	14,249	$	14,350
Record date	February 16, 2018		May 25, 2018		August 24, 2018
Payment date	March 23, 2018		June 29, 2018		September 28, 2018

The dividends paid to shareholders during the nine months ended September 30, 2018 were funded by cash generated from operations. Our Board of Directors reviews our dividend policy on a quarterly basis. Although there can be no assurance that we will continue to pay dividends or regarding the amount of future dividend payments, we expect to continue to pay a regular quarterly cash dividend.

The primary source of cash from financing activities is the net borrowings under our bank line of credit. We borrow for general corporate purposes as needed throughout the year. The outstanding short-term borrowings balance as of September 30, 2018 relates

31

to cash flow requirements due to the timing of cash receipts and cash payments. Another source of cash from financing activities are the proceeds from the exercise of stock options by employees and directors. In connection with the establishment of our dividend policy, we adopted a Dividend Reinvestment Plan in 2003.

We remain authorized to repurchase 1.7 million shares of our Common Stock pursuant to previous Board of Directors’ authorization. During the three and nine months ended September 30, 2018 and 2017, we repurchased our Common Stock as part of the dividend reinvestment related to treasury shares held within the Deferred Compensation Plan. The number of shares and value of shares repurchased were immaterial for the three and nine months ended September 30, 2018 and 2017.

Line of Credit

At September 30, 2018, we had a $300 million bank line of credit on which to draw for general corporate purposes. The amounts drawn under the line of credit are payable upon demand and generally bear interest at LIBOR plus 75 basis points. At September 30, 2018, there were $10.0 million in borrowings under the line of credit. At September 30, 2018, we also had outstanding $65.9 million in irrevocable standby letters of credit, which relate to payment obligations under our insurance programs. In connection with the issuance of the letters of credit, the amount available under the line of credit was reduced by$65.9 million to $224.2 million at September 30, 2018.

The line of credit requires us to satisfy one financial covenant. The covenant and its respective status at September 30, 2018 was as follows:

Covenant Description and Requirement	As of September 30, 2018
Funded debt(1) to EBITDA(2) ratio: less than 3.00 to 1.00	0.68

⁽¹⁾  All indebtedness for borrowed money including, but not limited to, reimbursement obligations in respect of letters of credit and guaranties of any such indebtedness.

⁽²⁾  Net income plus interest expense, income tax expense, depreciation, amortization.

As noted above, we were in compliance with our financial covenant at September 30, 2018 and we expect to remain in compliance. The line of credit expires on December 18, 2018. Although no assurances can be provided that we will renew the line of credit or secure other financing, we expect the line of credit to be renewed prior to expiration, or substituted with another form of financing.

Accounts and Notes Receivable

Decisions to grant or to extend credit to customers are made on a case-by-case basis and based on a number of qualitative and quantitative factors related to the particular client as well as the general risks associated with operating within the healthcare industry.

Fluctuations in net accounts and notes receivable are attributable to a variety of factors including, but not limited to, the timing of cash receipts from customers, the Company’s assessment of collectability and corresponding provision for bad debt expense and the inception, transition or termination of client relationships.

We deploy significant resources and have invested in tools and processes to optimize our credit and collections efforts. When appropriate, we utilize interest-bearing promissory notes as an alternative to accounts receivable to further enhance the collectability of amounts due by memorializing the amount and related payment schedule as well as securing additional business protections and guarantees.

32

Summarized below are the balances in our allowance for doubtful accounts, along with the provision for bad debts and net write-offs for each quarter for the nine months ended September 30, 2018. The change in our provision from during the first quarter of 2018 is primarily related to the corporate restructuring of two privately–held multi– state operators. The aggregate client account balances to which the reserve balances relate totaled $30.0 million, $98.2 million, $102.6 million, and $103.0 million as of December 31, 2017, March 31, 2018, June 30, 2018 and September 30, 2018, respectively.

	Allowance for Doubtful Accounts
	(in thousands)
Balance December 31, 2017	$	11,984
Provision for bad debts	37,137
Net write-offs of client accounts receivable	(216		)
Balance March 31, 2018	48,905
Provision for bad debts	2,250
Net write-offs of client accounts receivable	(1,446		)
Balance June 30, 2018	49,709
Provision for bad debts	3,000
Net write-offs of client accounts receivable	(4,079		)
Balance September 30, 2018	$	48,630

We evaluate our notes receivable for impairment quarterly and on an individual client basis. Notes receivable are generally evaluated for impairment when the respective clients are in bankruptcy, are subject to collections activity or are slow payers that are experiencing financial difficulties. In the event that the evaluation results in a determination that a note receivable is impaired, it is valued at the present value of expected future cash flows or at the market value of related collateral. The increase in impaired notes receivable and the related reserve during the nine months ended September 30, 2018 was related to the corporate restructuring of a privately held, multi-state operator that occurred during the first quarter of 2018. A result of the corporate restructuring was a long-term promissory note receivable of $10.0 million, net of reserve, which was finalized during the three months ended September 30, 2018.

A summary schedule of the our impaired notes receivable, and the related reserve, for the nine months ended September 30, 2018 is as follows:

	Balance December 31, 2017		Additions		Deductions			Balance September 30, 2018
	(in thousands)
Impaired notes receivable	$	6,854	$	20,582	$	(4,532	)	$	22,904
Reserve for impaired notes receivable	$	2,884	$	10,846	$	(1,938	)	$	11,792

Capital Expenditures

The level of capital expenditures is generally dependent on the number of new clients obtained. Such capital expenditures primarily consist of housekeeping and food service equipment purchases, laundry and linen equipment installations, computer hardware and software, and furniture and fixtures. Although we have no specific material commitments for capital expenditures through the end of calendar year 2018, we estimate that for 2018 we will have capital expenditures of approximately $4.5 million to $6.0 million. We believe that our cash from operations, existing cash and cash equivalents balance and credit line will be adequate for the foreseeable future to satisfy the needs of our operations and to fund our anticipated growth. However, should these sources not be sufficient, we would seek to obtain necessary capital from such sources as long-term debt or equity financing.

Material Off-Balance Sheet Arrangements

We have no material off-balance sheet arrangements, other than our irrevocable standby letter of credit previously discussed.

33

Item 3.  Quantitative and QualitativeDisclosures About Market Risk

At September 30, 2018, we had $89.9 million in cash, cash equivalents and marketable securities. The fair values of all of our cash equivalents and marketable securities are determined based on “Level 1” or “Level 2” inputs, which are 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. We place our cash investments in instruments that meet credit quality standards, as specified in our investment policy guidelines.

Investments in both fixed-rate and floating-rate investments carry a degree of interest rate risk. The market value of fixed rate securities may be adversely impacted by an increase in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates or if there is a decline in the fair value of our investments.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are intended to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934 (the “Exchange Act”), such as this Form 10-Q, is reported in accordance with Securities and Exchange Commission rules.

Based on their evaluation as of September 30, 2018, pursuant to Exchange Act Rule 13a-15(b), our Management, including our President and Chief Executive Officer and Chief Financial Officer, believe our disclosure controls and procedures (as defined in Exchange Act 13a-15(e)) are effective.

Changes in Internal Controls over Financial Reporting

In connection with the evaluation pursuant to Exchange Act Rule 13a-15(d) of our internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) by our Management, including our President and Chief Executive Officer and Chief Financial Officer, no changes during the quarter ended September 30, 2018 were identified that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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 clients 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 clients. In such agreements, the Company is responsible for the day-to-day management of employees located at the clients’ facilities. The Company also provides services on the basis of management-only agreements for a limited number of clients. The agreements with clients typically provide for renewable one year service terms, cancelable 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 clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of a client’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 client facility.

Dietary consists of managing the clients’ 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, 2017 has been derived from, and does not include, all of the disclosures contained in the financial statements for the year ended December 31, 2017. 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, 2017. The results of operations for the nine months ended September 30, 2018 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. 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 receivables from contracts with customers. Accounts receivable initially are recorded at the transaction amount, and 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 probable losses. 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. Notes receivable 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.

Refer to Note 3— Accounts and Notes Receivable herein for further information.

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 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.

Revenue Recognition

The Company recognizes revenue from service agreements 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification subtopic 606 Revenue from Contracts with Customers (“ASC 606”) became effective and was adopted by the Company as of January 1, 2018, by applying the modified retrospective method for contracts that were not completed as of January 1, 2018. The standard 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 which the Company recognizes is based on the consideration which the Company expects to be entitled to in exchange for contracted promised goods and services. The adoption of this standard did not have a material impact to the Company's accounting for revenue earned relating to the Housekeeping and Dietary segments. The Company also did not recognize an opening adjustment to retained earnings as a result of the adoption of the standard. See Note 2—Revenue herein for additional revenue disclosure that is being presented as a result of the newly adopted standard.

Prior period amounts were not adjusted and continue to be reported in accordance with previous guidance.

Income Taxes

The Company uses 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 period. The Company accrues for probable tax obligations as required by facts and circumstances in 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 basis 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 calculated 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 at least annually during the fourth quarter of each year 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 nine months ended September 30, 2018.

Concentrations of Credit Risk

The financial instruments that are subject to concentrations of credit risk are cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. The Company’s marketable securities are fixed income investments which are highly liquid and can be readily purchased or sold through established markets. At September 30, 2018 and December 31, 2017, 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 clients are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s clients 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 clients participate. As a result, the Company may not know the full effects of such programs until these laws are fully implemented and governmental agencies issue applicable regulations or guidance.

Recent Accounting Pronouncements

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize assets and liabilities on their balance sheet related to the rights and obligations created by most leases, while continuing to recognize expenses on their income statements over the lease term. It will also require disclosures designed to give financial statement users information regarding the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted for all entities. The Company will adopt ASU 2016–02 as of January 1, 2019 and will apply certain practical expedients offered in the guidance, such as those that state that the Company need not reassess whether expired or existing contracts contain leases, reevaluate the classification of expired or existing leases, or reassess initial direct costs for existing leases. Management has substantially completed the process of identifying existing lease contracts and is currently performing detailed evaluations of the leases under the new accounting requirements. The Company believes the most significant changes to the financial statements relate to the recognition of right–of–use assets and offsetting lease liabilities in the consolidated balance sheet for operating leases. The actual impact on the consolidated balance sheet will be contingent upon the Company's population of operating leases at adoption, however Management does not expect the standard to have a material impact on cash flows or results of operations.

In January 2017, the FASB issued Accounting Standards Update 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 no longer requires companies to perform a hypothetical purchase price allocation to measure impairment, eliminating step 2 of the goodwill impairment test. Instead, impairment will be measured using the difference of the carrying amount to the fair value of goodwill on a reporting unit basis. The guidance is effective for annual reporting periods beginning after December 15, 2019, but early adoption is permitted. The Company has elected to early adopt ASU 2017-04 for the annual evaluation which will be performed during the fourth quarter of 2018.

Note 2—Revenue

The Company disaggregates its consolidated revenues by reportable segment, as Management evaluates the nature, amount, timing and uncertainty of the Company’s revenues by segment. Refer to Note 12—Segment Information herein as well as the information below regarding the Company’s reportable segments.

Housekeeping

Housekeeping accounted for approximately 48.5%, or $734.2 million, and 53.7%, or $733.7 million, of the Company’s consolidated revenues for the nine months ended September 30, 2018 and 2017, respectively. The services provided under this segment include managing clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of the clients’ facilities, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at the clients’ facilities. Upon beginning service with a client 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 client requests. Such management personnel also oversee the execution of various cost and quality control procedures including continuous training and employee evaluation, and on-site testing for infection control.

Dietary

Dietary services represented approximately 51.5%, or $778.2 million, and 46.3%, or $633.0 million, of the Company’s consolidated revenues for the nine months ended September 30, 2018 and 2017, respectively. Dietary services consist of managing clients’ 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 being provided by a District Manager specializing in dietary services, as well as a registered dietitian. The Company also offers clinical consulting services to facilities which if contracted is a service bundled within the monthly service provided to clients. Upon beginning service with a client 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 client requests. Such management personnel also oversee the execution of various cost- and quality-control procedures including continuous training and employee evaluation.

Revenue Recognition

Substantially 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 expects to be 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 contracts with its customers. Such contracts typically provide for a renewable one year service term, cancelable by either party upon 30 to 90 days' notice, after an initial period of 60 to 120 days. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account under ASC 606. 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 and that are substantially the same and that have the same pattern of transfer to the customer. Accordingly, 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 clients’ 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 not material as of September 30, 2018 and December 31, 2017.

The transaction price is the amount of consideration to which the Company expects to be 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 Management 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 the contracts contain payment terms that 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 September 30, 2018 and December 31, 2017, the value of the associated contract liabilities was not material.

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 significant majority of the Company’s contracts with customers have an initial term of one year or less, with renewable one year service terms, cancelable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days. For the purpose of disclosing the transaction price allocated to remaining performance obligations, the Company elected to apply practical expedients available under the guidance in ASC 606 to exclude from the calculation future revenues expected for the performance of services under contracts with variable consideration that are for a term of one year or less. Although only a small portion of the Company’s contracts have an original expected duration that exceeds one year, the Company has historically had, and expects to continue to have, favorable client retention rates. As of September 30, 2018, the revenue expected to be recognized with the fixed transaction price associated with the remaining performance obligations under the Company’s existing contracts with a term greater than one year is $67.9 million for the remainder of 2018, $271.7 million for 2019, $271.7 million for 2020, $271.7 million for 2021, $271.7 million for 2022 and $339.6 million thereafter.

The Company makes credit decisions on a case–by–case basis after reviewing a number of qualitative and quantitative factors related to the specific client as well as current industry variables that may impact that client. There are a variety of factors that impact a client’s ability to pay in accordance with the Company’s service agreements. These factors include, but are not limited to, fluctuating census numbers, litigation costs and the client’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 client’s cash flows and their ability to make timely payments. However, the client's obligation to pay the Company in accordance with the service agreements are not contingent upon the client’s cash flows. Notwithstanding the Company’s efforts to minimize its credit risk exposure, the aforementioned factors, as well as other factors that impact client 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.

The Company’s net current accounts and notes receivable balance decreased from December 31, 2017. Fluctuations in net accounts and notes receivable are generally attributable to a variety of factors including, but not limited to, the timing of cash receipts from customers and the inception, transition or termination of client relationships. However, the Company offset its accounts and notes receivable with an increased allowance for doubtful accounts in the first quarter 2018 related primarily to corporate restructurings of two privately-held, multi-state operators that occurred during the first quarter 2018. In addition, the Company converted approximately $24.8 million of accounts receivable to long-term notes receivable, due to the achievement of key operational and financial milestones related to the 2017 dining and nutrition expansion with Genesis HealthCare. Also, in the third quarter of 2018 the Company finalized an agreement for a long-term promissory note receivable related to the previously mentioned corporate restructurings from the first quarter 2018. The promissory note receivable was $10.0 million, net of reserve, and was finalized during the three months ended September 30, 2018. Prior to the promissory note being finalized, the corresponding accounts receivable balance was net of a $10.0 million allowance for doubtful accounts reserve which was originally recorded during the first quarter 2018. As a result of the promissory note, the Company reclassified the reserve balance to an allowance for doubtful accounts on the Company’s long-term notes receivable.

The Company deploys significant resources and has invested in tools and processes to optimize Management’s credit and collections efforts. When appropriate, the Company utilizes interest-bearing promissory notes as an alternative to accounts receivable to enhance the collectability of amounts due, by instituting a definitive repayment plan and providing a means by which to further evidence the amounts owed. As of September 30, 2018 and December 31, 2017, the Company had $66.5 million and $36.6 million, net of reserves, respectively, of such promissory notes outstanding. In addition, the Company may assist clients who are adjusting to changes in their cash flows by amending the Company’s agreements from full-service to management-only arrangements, or by modifying contractual payment terms to accommodate clients who have in good faith established clearly-defined plans for addressing cash flow issues. These efforts are intended to minimize the Company’s collections risk while maintaining relationships with the clients.

Allowance for Doubtful Accounts

9 Months Ended

Sep. 30, 2018

Receivables [Abstract]

Allowance for Doubtful Accounts

Note 4— Allowance for Doubtful Accounts

The allowance for doubtful accounts is established when the Company determines that it is probable that receivables have been impaired and the Company can reasonably estimate the amount of the losses. The related provision for bad debts is charged to costs of services provided in the Company’s Consolidated Statements of Comprehensive Income. The allowance for doubtful accounts is evaluated based on the Company’s ongoing review of accounts and notes receivable and is inherently subjective as it requires estimates susceptible to significant revision as more information becomes available.

The Company has had varying collections experience with respect to its accounts and notes receivable. The Company has sometimes extended the period of payment for certain clients beyond contractual terms. In order to provide for such collection issues and the general risk associated with the granting of credit terms, the Company recorded bad debt provisions (in Allowance for Doubtful Accounts) of $42.4 million and $4.0 million for the nine months ended September 30, 2018 and 2017, respectively. The increase in the provision for bad debts period-over-period is primarily related to corporate restructurings of two privately-held, multi-state operators that occurred during the first quarter 2018.

In making the Company’s credit evaluations, in addition to analyzing and anticipating, where possible, the specific cases described above, Management considers the general collection risk associated with trends in the long-term care industry. The Company establishes credit limits, performs ongoing credit evaluations and monitors accounts to minimize the risk of loss. Despite the Company’s efforts to minimize credit risk exposure, clients could be adversely affected if future industry trends change in such a manner as to negatively impact their cash flows. If the Company’s clients 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.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 8—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 September 30, 2018 and 2017, the Company recorded unrealized losses of $0.5 million and unrealized gains of $0.1 million on marketable securities, respectively. For the nine months ended September 30, 2018 and 2017, the Company recorded unrealized losses of $1.5 million and unrealized gains of $1.2 million on marketable securities, respectively.

For the three months ended September 30, 2018 and 2017, the Company received total proceeds, less the amount of interest received, of $2.9 million and $5.7 million, respectively, from sales of available-for-sale municipal bonds. For the three months ended September 30, 2018 and 2017, these sales resulted in realized losses of less than $0.1 million and realized gains of $0.2 million, respectively. For the nine months ended September 30, 2018 and 2017, the Company received total proceeds, less the amount of interest received, of $8.7 million and $20.4 million, respectively, from sales of available-for-sale municipal bonds. For the nine months ended September 30, 2018 and 2017, these sales resulted in realized losses of $0.2 million and less than $0.1 million, respectively, which were recorded in “Other income, net – Investment and interest” 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).

The following tables provide fair value measurement information for the Company’s marketable securities and deferred compensation fund investments as of September 30, 2018 and December 31, 2017:

At September 30, 2018, the unrecognized compensation cost related to unvested stock options and awards was $15.3 million. The weighted average period over which these awards will vest is approximately 2.7 years.

2012 Equity Incentive Plan

The Company’s Second Amended and Restated 2012 Equity Incentive Plan (the “Plan”) provides that current or prospective officers, employees, non-employee directors and advisors can receive share-based awards such as stock options, restricted stock, restricted stock units and other stock awards. The Plan seeks to promote the highest level of performance by providing an economic interest in the long-term success of the Company.

As of September 30, 2018, 2.9 million shares of common stock were reserved for issuance under the Plan, including 0.5 million shares available for future grant. No stock award will have a term in excess of ten years. All awards granted under the Plan become vested and exercisable ratably over a five year period on each yearly anniversary of the grant date.

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 Plan.

Stock Options

A summary of stock options outstanding under the Plan as of December 31, 2017 and changes during the nine months ended September 30, 2018 is as follows:

The total intrinsic value of options exercised during the nine months ended September 30, 2018 and 2017 was $5.9 million and $13.3 million, respectively.

The fair value of stock option awards granted in 2018 and 2017 was estimated on the date of grant using the Black-Scholes option valuation model with the following assumptions:

	Nine Months Ended September 30,
	2018		2017
Risk-free interest rate	2.1	%	2.0	%
Weighted average expected life	5.8 years		5.8 years
Expected volatility	21.4	%	25.1	%

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 2.3 million shares available for future grant at September 30, 2018.

The expense associated with the options granted under the ESPP during the nine months ended September 30, 2018 and 2017 was estimated on the date of grant using the Black-Scholes option valuation model with the following assumptions:

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 September 30, 2018. At the time of issuance, such shares are accounted for at cost as treasury stock.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Note 11— Income Taxes

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Act”), which significantly changed U.S. tax law. The Act lowered the Company’s U.S. statutory federal income tax rate from 35% to 21% effective January 1, 2018. Year to date, the Company has recognized a provision for income taxes of $12.9 million.

The 2018 estimated annual effective tax rate is expected to be approximately 21% to 23%. The actual annual effective tax rate will be impacted by the tax effects of option exercises or 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 for the nine months ended September 30, 2018 for such discrete items was approximately $1.2 million.

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 2018 effective tax rate will likely vary from the estimate depending on the availability of tax credits and the exercise of stock options and vesting of share-based awards.

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, 2013 through 2017 (with regard to U.S. federal income tax returns) and December 31, 2012 through 2017 (with regard to various state and local income tax returns), the tax years which remain subject to examination by major tax jurisdictions as of September 30, 2018.

The Company may from time to time be assessed interest or penalties by taxing jurisdictions, although any such assessments historically have been minimal and immaterial to its financial results. When the Company has received an assessment for interest and/or penalties, it will be classified in the financial statements as selling, general and administrative expense. In addition, any interest or penalties relating to recognized uncertain tax positions would also be recorded in selling, general and administrative expense.

Segment Information

Note 12—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 client 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 service agreements, 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, bad debt expense, information technology costs, depreciation, amortization of finite-lived intangible assets, share based compensation costs and other corporate-specific costs, are not 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

Note 13—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:

Weighted average number of common shares outstanding - diluted	74,579	74,538	74,598	74,252

⁽¹⁾  Certain outstanding equity awards are anti-dilutive and were therefore excluded from the calculation of the weighted average number of diluted common shares outstanding. During the three and nine months ended September 30, 2018, stock options to purchase 0.6 million shares having a weighted average exercise price of $42.79 and $42.70 per share, respectively, were excluded. During the three months ended September 30, 2017, there were no anti-dilutive stock options, and during the nine months ended September 30, 2017, stock options to purchase 0.5 million shares having a weighted average exercise price of $39.38 per share were excluded. During the three and nine months ended September 30, 2018, 0.1 million restricted stock units were excluded. During the three and nine months ended September 30, 2017, there were no anti-dilutive restricted stock units.

Other Contingencies

Note 14— Other Contingencies

Line of Credit

At September 30, 2018, the Company had a $300 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 LIBOR plus 75 basis points. At September 30, 2018, there were $10.0 million in borrowings under the line of credit. The line of credit requires the Company to satisfy one financial covenant, with which the Company is in compliance as of September 30, 2018 and expects to remain in compliance. The line of credit expires on December 18, 2018, and although no assurances can be provided that the Company will renew the line of credit or secure other financing, the Company expects the line of credit to be renewed prior to expiration, or substituted with another form of financing.

At September 30, 2018, the Company also had outstanding $65.9 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$65.9 million to $224.2 million at September 30, 2018.

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. The Company believes it is not a party to, nor are any of its properties the subject of, any pending legal proceeding or governmental examination that would have a material adverse effect on the Company’s consolidated financial condition or liquidity.

Government Regulations

The Company’s clients are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s clients are highly reliant on Medicare, Medicaid and third party payors’ reimbursement funding rates. New legislation or additional changes in existing regulations could directly impact the governmental reimbursement programs in which the clients participate. The full effect of any such programs would not be realized until these laws are fully implemented and government agencies issue applicable regulations or guidance.

Description of Business and Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2018

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 clients 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 clients. In such agreements, the Company is responsible for the day-to-day management of employees located at the clients’ facilities. The Company also provides services on the basis of management-only agreements for a limited number of clients. The agreements with clients typically provide for renewable one year service terms, cancelable 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 clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of a client’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 client facility.

Dietary consists of managing the clients’ 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, 2017 has been derived from, and does not include, all of the disclosures contained in the financial statements for the year ended December 31, 2017. 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, 2017. The results of operations for the nine months ended September 30, 2018 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. 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 receivables from contracts with customers. Accounts receivable initially are recorded at the transaction amount, and 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 probable losses. 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. Notes receivable 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.

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 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.

Revenue Recognition

The Company recognizes revenue from service agreements 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification subtopic 606 Revenue from Contracts with Customers (“ASC 606”) became effective and was adopted by the Company as of January 1, 2018, by applying the modified retrospective method for contracts that were not completed as of January 1, 2018. The standard 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 which the Company recognizes is based on the consideration which the Company expects to be entitled to in exchange for contracted promised goods and services. The adoption of this standard did not have a material impact to the Company's accounting for revenue earned relating to the Housekeeping and Dietary segments. The Company also did not recognize an opening adjustment to retained earnings as a result of the adoption of the standard.

Income Taxes

The Company uses 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 period. The Company accrues for probable tax obligations as required by facts and circumstances in 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 basis 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 calculated 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 at least annually during the fourth quarter of each year 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 financial instruments that are subject to concentrations of credit risk are cash and cash equivalents, marketable securities, deferred compensation funding and accounts and notes receivable. The Company’s marketable securities are fixed income investments which are highly liquid and can be readily purchased or sold through established markets. At September 30, 2018 and December 31, 2017, 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 clients are concentrated in the healthcare industry and are primarily providers of long-term care. The revenues of many of the Company’s clients 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 clients participate. As a result, the Company may not know the full effects of such programs until these laws are fully implemented and governmental agencies issue applicable regulations or guidance.

Recent Accounting Pronouncements

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize assets and liabilities on their balance sheet related to the rights and obligations created by most leases, while continuing to recognize expenses on their income statements over the lease term. It will also require disclosures designed to give financial statement users information regarding the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted for all entities. The Company will adopt ASU 2016–02 as of January 1, 2019 and will apply certain practical expedients offered in the guidance, such as those that state that the Company need not reassess whether expired or existing contracts contain leases, reevaluate the classification of expired or existing leases, or reassess initial direct costs for existing leases. Management has substantially completed the process of identifying existing lease contracts and is currently performing detailed evaluations of the leases under the new accounting requirements. The Company believes the most significant changes to the financial statements relate to the recognition of right–of–use assets and offsetting lease liabilities in the consolidated balance sheet for operating leases. The actual impact on the consolidated balance sheet will be contingent upon the Company's population of operating leases at adoption, however Management does not expect the standard to have a material impact on cash flows or results of operations.

In January 2017, the FASB issued Accounting Standards Update 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 no longer requires companies to perform a hypothetical purchase price allocation to measure impairment, eliminating step 2 of the goodwill impairment test. Instead, impairment will be measured using the difference of the carrying amount to the fair value of goodwill on a reporting unit basis. The guidance is effective for annual reporting periods beginning after December 15, 2019, but early adoption is permitted. The Company has elected to early adopt ASU 2017-04 for the annual evaluation which will be performed during the fourth quarter of 2018.

Reportable Operating 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, bad debt expense, information technology costs, depreciation, amortization of finite-lived intangible assets, share based compensation costs and other corporate-specific costs, are not 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.
