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 June 30, 2017, the Company held foreign exchange contracts that were not designated as hedging under ASC 815 with an aggregate notional value of $814.6 million (December 31, 2016 — $665.6 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 and six months ended June 30, 2017, the impact of foreign exchange contracts on net income was a gain of $17.6 million (June 30, 2016 — gain of $0.2 million) and a gain of $20.7 million (June 30, 2016 — loss of $4.2 million), respectively. As at June 30, 2017, the Company held foreign exchange contracts that were designated as hedging under ASC 815 with an aggregate nominal amount of $54.6 million (December 31, 2016 — $108.6 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 and six months ended June 30, 2017 was a net unrealized gain of $2.4 million (June 30, 2016 — loss of $2.9 million) and a net unrealized gain of $3.7 million (June 30, 2016 — loss of $5.0 million), respectively. 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 and six months ended June 30, 2017, the amount recognized within general, administrative and corporate expenses for settled foreign exchange contracts was a realized gain of $0.9 million (June 30, 2016 — loss of $1.4 million) and a net realized gain of $1.2 million (June 30, 2016 — loss of $2.5 million), respectively. Interest Rate Swaps. In 2014, the Company decided to let its interest rate program roll-off and not renew maturing positions. This decision was made after an extensive reassessment of the costs of maintaining an interest rate swap program in a steep yield curve environment. In addition, the continued uncertainty in the global economy and low inflation make it difficult to gauge the timing and speed of interest rate rises by the Federal Reserve. On May 9, 2016, the Company terminated all remaining outstanding interest rate swaps (notional value of $256.3 million) under its International Swap Dealers Association agreement. As at June 30, 2017 and December 31, 2016, the Company no longer had outstanding interest rate swaps. There was no charge in respect of the interest rate swaps for the three and six months ended June 30, 2017 (June 30, 2016 — loss of $0.6 million and loss of $3.4 million), respectively.
