Fair Value Disclosures [Abstract] |
Fair Value Measurements | 4. Fair Value Measurements The accounting guidance on fair value measurements defines fair value, establishes a framework for measuring fair value under GAAP, and expands disclosures about fair value measurements. The guidance is applicable for all financial assets and financial liabilities and for all nonfinancial assets and nonfinancial liabilities recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). Fair value is defined as the exchange price that would be received from selling an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions and risk of nonperformance. Fair Value Hierarchy Accounting guidance on fair value measurements requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1 — Quoted (unadjusted) prices in active markets for identical assets or liabilities. The Company did not have any Level 1 assets as of December 31, 2019 and September 30, 2019. Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities 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 asset or liability. The Company’s Level 2 assets as of December 31, 2019 and September 30, 2019 consisted of money market funds, commercial paper instruments and corporate bonds. Level 3 — Unobservable inputs to the valuation methodology that are supported by little or no market activity and that are significant to the measurement of the fair value of the assets or liabilities. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation. The Level 3 liability as of September 30, 2019 consisted of contingent consideration obligations related to the fiscal 2016 acquisition of NorMedix, Inc. (“NorMedix”). Consideration owed to the sellers of NorMedix from revenue and value-creating milestones achieved through September 30, 2019 totaling $3.2 million was paid during the three months ended December 31, 2019, with $0.6 million and $2.6 million classified as cash flows used in operating and financing activities, respectively, on the condensed consolidated statements of cash flows. In valuing Level 3 assets and liabilities, the Company is required to maximize the use of quoted market prices and minimize the use of unobservable inputs. Assets and Liabilities Measured at Fair Value on a Recurring Basis In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The following table presents information about the Company’s assets measured at fair value on a recurring basis as of December 31, 2019:

There were no transfers of assets or liabilities between amounts measured using Level 1, Level 2, or Level 3 fair value measurements in fiscal 2020 and fiscal 2019. Valuation Techniques The valuation techniques used to measure the fair value of assets are as follows: Cash equivalents — These assets are classified as Level 2 and are carried at historical cost which is a reasonable estimate of fair value because of the relatively short time between origination of the instrument and its expected realization. Available-for-sale securities — Fair market values for these assets are based on quoted vendor prices and broker pricing in active markets underlying the securities where all significant inputs are observable. To ensure the accuracy of quoted vendor prices and broker pricing, the Company performs regular reviews of investment returns to industry benchmarks and sample tests of individual securities to validate quoted vendor prices with other available market data.
