The fair value of derivative instruments is determined using Level 2 inputs. Generally, the Company obtains the Level 2 inputs from its counterparties. Substantially all of the inputs are observable in the marketplace throughout the full term of the instruments, which can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. The fair value of the Company’s interest rate swap was determined using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of the derivative. This analysis reflected the contractual terms of the derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves and implied volatilities.
Stock appreciation rights, deferred compensation and redeemable noncontrolling interests. The fair values of stock appreciation rights, deferred compensation and redeemable noncontrolling interests are determined using Level 3 inputs. These inputs include a volatility rate based on comparable entities, a discount rate, the expected time to redemption of the liabilities, historical values of the book equity of certain subsidiaries and market information for comparable entities. The use of these inputs to derive the fair value of the liabilities at a point in time can result in volatility to the financial statements. See Note 10, “Stock Appreciation Rights, Deferred Compensation and Redeemable Noncontrolling Interests,” for a reconciliation of the beginning and ending balances.
Contingent consideration. In connection with the acquisition of Titan, the Company assumed certain contingent consideration arrangements. The fair value of contingent consideration is determined using Level 3 inputs. These inputs include a discount rate and probability adjusted payments. During the nine months ended January 31, 2020, the Company recorded expense of $1.6 million related to the contingent consideration, which was included in other (expense) income in the Condensed Consolidated Statement of Operations and Comprehensive Income.
Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
Disclosures are required for certain assets and liabilities that are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. Such measurements of fair value relate primarily to assets and liabilities measured at fair value in connection with business combinations and long-lived asset impairments. For more information on business combinations, see Note 3, “Business Acquisitions.” There were no material long-lived asset impairments during the nine months ended January 31, 2020 or 2019.
