Fair Value Disclosure

The financial assets of the Company measured at fair value on a recurring basis are included in cash equivalents and other assets. The Company classifies its cash equivalents and other assets, except for its investment in an auction rate security within Level 1 or Level 2 in the fair value hierarchy because the Company uses quoted prices in active markets or alternative pricing sources and models using market observable inputs to determine their fair value. The Company’s investment in an auction rate security is classified within Level 3 of the fair value hierarchy as the determination of its fair value was not based on observable inputs as of March 31, 2019 and June 30, 2018. The Company used discounted cash flows to estimate the fair value of the auction rate security as of March 31, 2019 and June 30, 2018. The material factors used in preparing the discounted cash flows are (i) the discount rate utilized to present value the cash flows, (ii) the time period until redemption and (iii) the estimated rate of return.

The Company measures the fair value of outstanding debt for disclosure purposes on a recurring basis. As of March 31, 2019 and June 30, 2018, total debt of $22.7 million and $116.2 million, respectively, are reported at amortized cost. This outstanding debt is classified as Level 2 as it is not actively traded. The amortized cost of the outstanding debt approximates the fair value.

Financial Assets Measured on a Non-recurring Basis

The Company's non-marketable equity securities are investments in privately held companies without readily determinable fair values. Prior to July 1, 2018, the Company accounted for its investment in non-marketable equity securities at cost less impairment. Realized gains and losses on non-marketable equity securities sold or impaired were recognized in other income (expense), net. Upon adoption of the new guidance, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, on July 1, 2018, the Company classifies its investment in non-marketable equity instruments as Level 3 as the fair value is determined using significant unobservable inputs. During the three and nine months ended March 31, 2019 the Company did not record any upward or downward adjustments to the carrying values of the non-marketable equity securities. During the three months ended March 31, 2019, the Company recorded impairment charges of $0.7 million for its non-marketable equity securities which had an initial cost basis of $0.7 million as it was determined the carrying value of the investments were not recoverable. For the three and nine months ended March 31, 2018, the Company did not record any other-than-temporary impairments on financial assets required to be measured at fair value on a nonrecurring basis.

There were no transfers of financial assets measured on a non-recurring basis between Level 1, Level 2 or Level 3 securities during the three and nine months ended March 31, 2019 and 2018.
