Marketable Securities

4. Marketable Securities

The Company invests in marketable securities that are classified as available-for-sale and records them at fair value in the accompanying unaudited Consolidated Balance Sheets. Marketable securities reported as current assets represent investments that mature within one year from the balance sheet date. Long-term marketable securities represent investments with maturity dates greater than one year from the balance sheet date. The securities are valued using matrix pricing and benchmarking and classified within Level 2 of the fair value hierarchy because they are not actively traded. Matrix pricing is a mathematical technique used to value securities by relying on the securities’ relationship to other benchmark quoted prices.

Unrealized gains and losses are excluded from earnings and reported as a separate component of “Total other comprehensive income, net of tax” in the accompanying unaudited Consolidated Statement of Comprehensive Income until the security is sold or matures. Gains or losses realized from sales of marketable securities are computed based on the specific identification method and recognized as a component of "Other income (expenses), net" in the accompanying unaudited Consolidated Statements of Operations. During the nine months ended June 30, 2021, there were insignificant sales of marketable securities. During the nine months ended June 30, 2020, the Company sold marketable securities with a fair value and amortized cost of $2.5 million, and recognized a net gain of less than $0.1 million in this period. As a result, during the nine months ended June 30, 2020, the Company collected cash proceeds of $2.5 million from the sale of marketable securities and reclassified net unrealized holding gains of less than $0.1 million from accumulated other comprehensive income into “Other expenses, net” in the accompanying unaudited Consolidated Statements of Operations as a result of these transactions.

The following is a summary of the amortized cost and the fair value, including accrued interest receivable and unrealized holding gains (losses) on the short-term and long-term marketable securities as of June 30, 2021 and September 30, 2020 (in thousands):

			Gross		Gross

The fair values of the marketable securities by contractual maturities at June 30, 2021 are presented below (in thousands):

	Fair Value
Due in one year or less	$	101
Due after one year through five years		—
Due after five years through ten years		—
Due after ten years		3,637
Total marketable securities	$	3,738

Expected maturities could differ from contractual maturities because the security issuers may have the right to prepay obligations without prepayment penalties.

The Company reviews the marketable securities for impairment at each reporting period to determine if any of the securities have experienced an other-than-temporary decline in fair value. The Company considers factors, such as the length of time and extent to which the market value has been less than the cost, the financial condition and near-term prospects of the issuer, the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of its amortized cost basis. If the Company believes that an other-than-temporary decline in fair value has occurred, it writes down the investment to its fair value and recognizes the credit loss in earnings and the non-credit loss in accumulated other comprehensive income or loss. There was an insignificant amount of securities in an unrealized loss position as of June 30, 2021. There were no securities in an unrealized loss position as of September 30, 2020.

Cash equivalents of less than $0.1 million at June 30, 2021 consist of money market funds and are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets. There were no cash equivalents classified within Level 1 of the fair value hierarchy as of September 30, 2020. Cash equivalents of $0.1 million as of September 30, 2020, consist primarily of treasury bills and agency bonds and are classified within Level 2 of the fair value hierarchy because they are not actively traded. Cash equivalents from Level 1 and Level 2 are recorded in “Cash and cash equivalents” within the accompanying unaudited Consolidated Balance Sheet.
