Use of estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities that are subject to judgment and use of estimates include sales allowances and allowances for doubtful accounts, contract assets, the recoverability and related impairment of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment and intangible assets, right-of-use assets and operating lease liabilities, contingencies, the valuation and assumptions underlying stock-based compensation and other equity instruments, and valuation of derivatives.

Allowance for doubtful accounts

Allowance for Doubtful Accounts

The Company determines its allowance for doubtful accounts based on historical write-off experience and specific circumstances that make it likely that recovery will not occur. The Company reviews the allowance for doubtful accounts periodically and assesses the aging of account balances, with an emphasis on those that are past due over ninety days. Account balances are charged off against the allowance when the Company determines that it is probable the receivable will not be recovered.

The Company considers the need to adjust historical information to reflect the extent to which the Company expects current conditions and reasonable and supportable forecasts to differ from the conditions that existed for the period over which historical information was evaluated. The primary current and future economic indicators that the Company uses to develop its current estimate of expected credit losses include the current and forecast U.S. Gross Domestic Product (GDP).

The Company calculates the expected credit losses on a pool basis for those trade receivables that have similar risk characteristics. For those trade receivables that do not share similar risk characteristics, the allowance for doubtful accounts is calculated on an individual basis. Risk characteristics relevant to the Company’s accounts receivable include revenue billing model and aging status.

Fair value measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Accounting standards describe a fair value hierarchy based on the following three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

•Level 1 — Quoted prices in active markets for identical assets, liabilities, or funds.

•Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The carrying amounts of cash equivalents, accounts receivable, prepaid and other current assets, accounts payable, and accrued expenses and other current liabilities approximate fair value because of the short maturity of these items.
