Offsetting Assets and Liabilities

Our qualifying master netting agreements are written, legally enforceable bilateral agreements that (1) create a single legal obligation for all individual transactions covered by the agreement to the non-defaulting entity upon an event of default of the counterparty, including bankruptcy, insolvency, or similar proceeding, and (2) provide the non-defaulting entity the right to accelerate, terminate, and close-out on a net basis all transactions under the agreement and to liquidate or set off collateral promptly upon an event of default of the counterparty. As it relates to derivative instruments, in certain instances we have the option to report derivatives that are subject to a qualifying master netting agreement on a net basis, we have elected to report these instruments as gross assets and liabilities on the Condensed Consolidated Balance Sheet.

To further mitigate the risk of counterparty default related to derivative instruments, we maintain collateral agreements with certain counterparties. The agreements require both parties to maintain collateral in the event the fair values of the derivative financial instruments meet established thresholds. In the event that either party defaults on the obligation, the secured party may seize the collateral. Generally, our collateral arrangements are bilateral such that we and the counterparty post collateral for the value of our total obligation to each other. Contractual terms provide for standard and customary exchange of collateral based on changes in the market value of the outstanding derivatives. The securing party posts additional collateral when their obligation rises or removes collateral when it falls, such that the net replacement cost of the non-defaulting party is covered in the event of counterparty default.

The composition of offsetting derivative instruments, financial assets, and financial liabilities was as follows.
