Fair Value Disclosures [Abstract] |
Financial Instruments and Fair Value Measurements | Note J. Financial Instruments and Fair Value Measurements The FASB authoritative guidance on fair value measurements defines fair value, provides a framework for measuring fair value, and requires certain disclosures about fair value measurements. The required disclosures focus on the inputs used to measure fair value. The guidance establishes the following hierarchy for categorizing these inputs:
Level 1 | — | Quoted market prices in active markets for identical assets or liabilities
Level 2 | — | Significant other observable inputs (e.g., quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs)
Level 3 | — | Significant unobservable inputs
There were no transfers of financial assets or liabilities measured at fair value between Level 1 and Level 2, and there were no Level 3 investments during fiscal 2023 or 2022. At both September 30, 2023 and 2022, the fair values of cash and cash equivalents, accounts and notes receivable, accounts payable and accrued liabilities, and short term borrowings and variable rate debt approximated their carrying values due to the short-term nature of these instruments. Cash and cash equivalents are classified as Level 1 within the fair value hierarchy. At both September 30, 2023 and 2022, Cabot had derivatives relating to foreign currency risks carried at fair value. The Company uses standard models with market-based inputs, which take into account the present value of estimated future cash flows and the ability of Cabot or the financial counterparty to perform. For interest rate and cross-currency swaps, the significant inputs to these models are interest rate curves for discounting future cash flows and are adjusted for credit risk. For forward foreign currency contracts, the significant inputs are interest rate curves for discounting future cash flows, and exchange rate curves of the foreign currency for translating future cash flows. These derivatives are classified as Level 2 instruments within the fair value hierarchy as the fair value determination was based on observable inputs. At both September 30, 2023 and 2022, the fair value of Guaranteed investment contracts, included in Other assets on the Consolidated Balance Sheets was $8 million. Guaranteed investment contracts were classified as Level 2 instruments within the fair value hierarchy as the fair value determination was based on other observable inputs. The carrying value and fair value of the long-term fixed rate debt were $1.08 billion and $1.04 billion, respectively, as of September 30, 2023 and $1.08 billion and $1.06 billion, respectively, as of September 30, 2022. The fair values of Cabot’s fixed rate long-term debt are estimated based on comparable quoted market prices at the respective period ends. The carrying amounts of Cabot’s floating rate long-term debt approximates the fair value. All such measurements are based on observable inputs and are classified as Level 2 within the fair value hierarchy. The valuation technique used is the discounted cash flow model.
