Foreign Exchange Contracts. The Company uses foreign exchange contracts to manage foreign currency risk. A foreign exchange contract involves an obligation to purchase or sell a specified currency at a future date at a price set at the time of the contract. Foreign exchange contracts will not eliminate fluctuations in the value of the Company’s assets and liabilities denominated in foreign currencies but rather allow it to establish a rate of exchange for a future point in time.

As at March 31, 2018, the Company held foreign exchange contracts that were not designated as hedging under ASC 815 with an aggregate notional value of $1,109.7 million (December 31, 2017 — $751.6 million). The foreign exchange contracts are recorded as derivatives at fair value with changes recorded as a change in fair value of derivatives in the statement of operations. For the three months ended March 31, 2018, the impact of foreign exchange contracts on net income was a gain of $23.5 million (March 31, 2017 — gain of $3.1 million).

As at March 31, 2018, the Company held foreign exchange contracts that were designated as hedging under ASC 815 with an aggregate nominal amount of $80.8 million (December 31, 2017 — $60.6 million). The foreign exchange contracts are recorded as derivatives at fair value in the balance sheet with the effective portion recorded in other comprehensive income and the ineffective portion recorded as a change in fair value of derivatives in the statement of operations. The contracts are considered to be effective and therefore the movement in other comprehensive income representing the effective portion for the three months ended March 31, 2018 was a net unrealized gain of $0.9 million (March 31, 2017 — gain of $1.3 million).

As the foreign exchange contracts settle, the realized gain or loss is reclassified from other comprehensive income into general, administration and corporate expenses of the statement of operations and other comprehensive income. For the three months ended March 31, 2018, the amount recognized within general, administrative and corporate expenses for settled foreign exchange contracts was a realized gain of $1.7 million (March 31, 2017 — gain of $0.3 million).
