(a)

We enter into long-term revenue agreements, which provide for pricing denominated in currencies other than the functional currency of the parties to the contract. This pricing feature was determined to be an embedded derivative which has been bifurcated for valuation and accounting purposes. The embedded derivative contracts and forward contracts are measured at fair value and included in other assets and/or other liabilities (note 7). The gains and losses due to the change in fair value are recognized in the statement of operations as part of other financing income (note 12). The fair value of the foreign currency embedded derivatives is determined to be a recurring Level 2 fair value measurement determined using a present value model. There were no transfers between categories in the fair value hierarchy.

(b)

As of July 31, 2016, the Bankruptcy Court had approved 65 helicopter lease rejections. In accordance with the guidance of ASC 852 Reorganizations, we have recorded the expected allowed claim from the lessors on the Bankruptcy Court’s approval of the lease rejection (note 10) with all lease related assets and liabilities adjusted to reorganization items, net (note 9). The lessors’ rights of enforcement for those claims will be subject to the applicable provisions of the Bankruptcy Code.
