4. DERIVATIVE FINANCIAL INSTRUMENTS

The Company enters into non-designated foreign currency derivatives, primarily comprised of foreign currency forward contracts, for which hedge accounting does not apply. The changes in the fair market value of these non-designated derivatives are included in other income/expense in the Company's consolidated statements of income. The Company uses non-designated foreign currency derivatives to hedge foreign-currency-denominated intercompany transactions and to partially mitigate the impact of foreign-currency fluctuations. The fair value of the non-designated foreign currency derivatives is based on third-party quotes.

As of September 30, 2017, the Company did not hold any non-designated derivative contracts. As of September 30, 2016, the Company held non-designated derivative contracts with notional amounts of 300 million Japanese yen ($3.0 million), 11.5 billion South Korean won ($10.4 million). Gains and losses related to non-designated derivative contracts are recorded as part of Other Income (Expense).

The following table summarizes gains (losses) related to derivative instruments not designated as hedging instruments during the three- and nine-month periods ended September 30, 2017 and 2016 (U.S. dollars in thousands):

The Company designates as cash-flow hedges those foreign currency forward contracts it enters to hedge forecasted intercompany transactions that are subject to foreign currency exposures. Changes in the fair value of these forward contracts designated as cash-flow hedges are recorded as a component of accumulated other comprehensive income (loss) within shareholders' equity (deficit), and are recognized in the consolidated statement of income during the period which approximates the time the hedged transaction is settled.

As of September 30, 2017, the Company held forward contracts designated as foreign currency cash flow hedges with notional amounts totaling 1.4 billion Japanese yen ($12.4 million) and 2.3 billion Japanese yen and 6.0 million euros ($22.7 million and $6.7 million, respectively) as of September 30, 2016 to hedge forecasted foreign-currency-denominated intercompany transactions. The fair value of these hedges were $0.3 million and ($2.1 million) as of September 30, 2017 and 2016, respectively. The contracts held at September 30, 2017 have maturities through June 2018, and accordingly, all unrealized gains and losses on foreign currency cash flow hedges included in accumulated other comprehensive loss will be recognized in current earnings over the next 9 months.

The following table summarizes gains (losses) related to derivative instruments recorded in other comprehensive income (loss) during the three- and nine-month periods ended September 30, 2017 and 2016 (U.S. dollars in thousands):

As of September 30, 2017 and December 31, 2016, there were $0.2 million and $0.6 million, respectively, of unrealized gains/(losses) included in accumulated other comprehensive loss related to foreign currency cash flow hedges. The remaining $69.4 million and $84.7 million as of September 30, 2017 and December 31, 2016, respectively, in accumulated other comprehensive loss are related to cumulative translation adjustments. The Company assesses hedge effectiveness at least quarterly. During the three and nine months ended September 30, 2017 and 2016, all hedges were determined to be effective.

The Company reports its derivatives at fair value as either other current assets or accrued expenses within its consolidated balance sheet. See Note 13 Fair Value.
