Derivatives not designated as hedges
The Partnership must meet specific criteria in order to apply hedge accounting. The Partnership uses derivatives to hedge exposures when it makes economic sense to do so, including circumstances in
which the hedging relationship does not qualify for hedge accounting as described in the following paragraph. The Partnership also will occasionally receive derivatives, such as equity warrants, in the ordinary course of business. Although these instruments are considered to be derivatives, their economic risk is similar to, and managed on the same basis as, other equity instruments the Partnership holds. Derivatives that do not qualify for hedge accounting are marked to market through operations.
