The methods that we use may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

        Assets and liabilities remeasured and disclosed at fair value on a recurring basis at July 31, 2020 and October 31, 2019 are set forth in the table below:

      Interest Rate Swap Contracts(548) (548)Income Approach

        We calculate the fair value of our interest rate swap contracts using quoted interest rate curves to calculate forward values and then discount the forward values.
        The discount rates for all derivative contracts are based on quoted swap interest rates or bank deposit rates. For contracts which, when aggregated by counterparty, are in a liability position, the rates are adjusted by the credit spread that market participants would apply if buying these contracts from our counterparties.
