## Cash and Cash Equivalents 

Cash and cash equivalents consist of cash on hand and marketable securities with original maturities of three months or less. The fair value of cash and cash equivalents approximates carrying value due to their short-term nature. At December 31, 2019, cash and cash equivalents included time deposits of approximately $931,000 that were in financial institutions outside the U.S. 

## Accounts Receivable and Allowance for Doubtful Accounts 

The Company extends credit based on an evaluation of a client's financial condition and, generally, collateral is not required. Accounts receivable are typically due upon receipt of the invoice and are stated on the Company's Consolidated Balance Sheets at amounts due from clients net of an estimated allowance for doubtful accounts. Accounts outstanding longer than the contractual payment terms are considered past due. The fair value of accounts receivable approximates book value due to their short-term contractual stipulations. 

The Company maintains an allowance for doubtful accounts for estimated losses resulting primarily from the inability of clients to make required payments. Such losses are accounted for as bad debt expense, while adjustments to invoices are accounted for as reductions to revenue. 

These allowances are established using historical write-off or adjustment information to project future experience and by considering the current creditworthiness of clients, any known specific collection problems, and an assessment of current industry and economic conditions. Actual experience may differ significantly from historical or expected loss results. The Company writes off accounts receivable when they become uncollectible, and any payments subsequently received are accounted for as recoveries. A summary of the activities in the allowance for doubtful accounts for the years ended December 31, 2019, 2018, and 2017 is as follows:

## Goodwill, Indefinite-Lived Intangible Assets, and Other Long-Lived Assets 

Goodwill is an asset that represents the excess of the purchase price over the fair value of the separately identifiable net assets (tangible and intangible) acquired in certain business combinations. Indefinite-lived intangible assets consist of trade names associated with acquired businesses. 

Goodwill and indefinite-lived intangible assets are not amortized, but are subject to impairment testing at least annually. Other long-lived assets consist primarily of property and equipment, deferred income tax assets, capitalized software, and amortizable intangible assets related to customer relationships, technology, and trade names with finite lives. Other long-lived assets are evaluated for impairment when impairment indicators are identified. 

Subsequent to a business acquisition in which goodwill and indefinite-lived intangibles are recorded as assets, post-acquisition accounting requires that both be tested to determine whether there has been an impairment. The Company performs an impairment test of goodwill and indefinite-lived intangible assets at least annually on October 1 of each year. The Company regularly evaluates whether events and circumstances have occurred which indicate potential impairment of goodwill or indefinite-lived intangible assets. When factors indicate that such assets should be evaluated for possible impairment between the scheduled annual impairment tests, the Company performs an interim impairment test. 

Goodwill impairment testing is performed on a reporting unit basis. If the fair value of the reporting unit exceeds its carrying value, including goodwill, goodwill is considered not impaired. If the carrying value of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The loss recognized cannot subsequently be reversed.
