In the normal course of business, we use derivative financial instruments to manage foreign currency exchange rate risk. Our derivative financial instruments consist of deliverable and non-deliverable foreign currency forward contracts.

For a cash flow hedge, the effective portion of the change in estimated fair value of a hedging instrument is recorded in Accumulated other comprehensive loss as a separate component of Shareholders’ Equity and is reclassified into Cost of services in the Consolidated Income Statements during the period in which the hedged transaction is recognized. For information related to derivatives designated as cash flow hedges that were reclassified into Cost of services during the three months ended November 30, 2020 and 2019, as well as those expected to be reclassified into Cost of services in the next 12 months, see Note 4 (Accumulated Other Comprehensive Loss) to these Consolidated Financial Statements.

Realized gains or losses and changes in the estimated fair value of foreign currency forward contracts that have not been designated as hedges were net gains of $28,324 and net losses $56,619 for the three months ended November 30, 2020 and 2019, respectively. Gains and losses on these contracts are recorded in Other income (expense), net in the Consolidated Income Statements and are offset by gains and losses on the related hedged items.

We utilize standard counterparty master agreements containing provisions for the netting of certain foreign currency transaction obligations and for the set-off of certain obligations in the event of an insolvency of one of the parties to the transaction. In the Consolidated Balance Sheets, we record derivative assets and liabilities at gross fair value. The potential effect of netting derivative assets against liabilities under the counterparty master agreements is as follows:
