Fair Value Disclosures [Abstract] |
Fair Value Measurements | Note 5. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Valuation techniques must maximize the use of observable inputs and minimize the use of unobservable inputs. When determining fair value measurements for assets and liabilities recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement as of the measurement date as follows: • Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 - Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity. The following table presents information about our financial assets that are measured at fair value and indicates the fair value hierarchy of the valuation inputs used (dollars in thousands) as of:

Government securities $2,377 at cost (b) |  |  | 2,361 |  |  |  | - |  |  |  | 2,361 |

Total assets |  | $ | 94,511 |  |  | $ | 60,610 |  |  | $ | 31,901 |
(a) Money market funds and other highly liquid investments with original maturities of 90 days or less are included within Cash and cash equivalents in the Condensed Consolidated Balance Sheets. (b) Government securities, commercial paper and corporate bonds with original maturities greater than 90 days are included within Marketable securities in the Condensed Consolidated Balance Sheets and classified as current or noncurrent based upon whether the maturity of the financial asset is less than or greater than 12 months. (c) Debt securities are included within Prepaid and other current assets and Other assets in the Condensed Consolidated Balance Sheets and classified as current or noncurrent based upon whether the maturity of the financial asset is less than or greater than 12 months. During the second quarter of fiscal year 2023, we obtained debt securities in a privately held company as part of a non-cash transaction. During the three and six months ended March 31, 2023, we recorded unrealized gains related to our marketable securities of $0.2 million and $0.3 million, respectively, within Accumulated other comprehensive loss. During the three and six months ended March 31, 2022, we recorded unrealized losses related to our marketable securities of $0.1 million and $0.2 million, respectively, within Accumulated other comprehensive loss. The carrying amounts of certain financial instruments, including cash held in banks, accounts receivable, and accounts payable, approximate fair value due to their short-term maturities and are excluded from the fair value tables above. Derivative financial instruments are recognized at fair value and are classified within Level 2 of the fair value hierarchy. See Note 6 – Derivative Financial Instruments for additional details. Long-term debt The estimated fair value of our Long-term debt is determined by Level 2 inputs and is based on observable market data including prices for similar instruments. As of March 31, 2023 and September 30, 2022, the estimated fair value of our Notes was $179.7 million and $155.3 million, respectively. The Notes are recorded at face value less transaction costs on our Condensed Consolidated Balance Sheets. The carrying amount of the Senior Credit Facilities (as defined in Note 14) approximates fair value given the underlying interest rate applied to such amounts outstanding is currently set to the prevailing market rate. Equity securities During the second quarter of fiscal year 2023, we obtained equity securities in a privately held company as part of a non-cash transaction. These equity securities are recognized at fair value and are classified within Level 2 of the fair value hierarchy. We have non-controlling equity investments in privately held companies. We evaluated the equity investments under the voting model and concluded consolidation was not applicable. We accounted for the investments by electing the measurement alternative for investments without readily determinable fair values and for which we do not have the ability to exercise significant influence. The non-marketable equity securities are carried at cost less any impairment, plus or minus adjustments resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, which is recorded within the Condensed Consolidated Statements of Operations. Investments without readily determinable fair values wer e $3.1 million as of March 31, 2023 and September 30, 2022, respectively. The investments are included within Other assets on the Condens ed Consolidated Balance Sheets. There have been no adjustments to the carrying value of the investments resulting from impairments or observable price changes.
