Aegon mitigates credit risk in derivative contracts by entering into collateral agreements, where practical, and in ISDA master  netting agreements for each of the Aegon’s legal entities to facilitate Aegon’s right to offset credit risk exposure. The credit support  agreement will normally dictate the threshold over which collateral needs to be pledged by Aegon or its counterparty. Transactions  requiring Aegon or its counterparty to post collateral are typically the result of over-the-counter derivative trades, comprised mostly of  interest rate swaps, currency swaps and credit swaps. These transactions are conducted under terms that are usual and customary to  standard long-term borrowing, derivative, securities lending and securities borrowing activities, as well as requirements determined by  exchanges where the bank acts as intermediary.
