10. Derivative Instruments and Hedging Activities

Foreign Currency Instruments

The Company designates certain foreign currency derivatives, primarily comprised of foreign currency forward contracts, as freestanding derivatives for which hedge accounting does not apply. The changes in the fair market value of these freestanding derivatives are included in selling, general, and administrative expenses in the Company’s condensed consolidated statements of income. The Company primarily uses freestanding 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 freestanding foreign currency derivatives is based on third-party quotes. The Company’s foreign currency derivative contracts are generally executed on a monthly basis.

The Company designates as cash flow hedges those foreign currency forward contracts it enters into to hedge forecasted inventory purchases and intercompany management fees that are subject to foreign currency exposures. Forward contracts are used to hedge forecasted inventory purchases over specific months. Changes in the fair value of these forward contracts, excluding forward points, designated as cash flow hedges are recorded as a component of accumulated other comprehensive loss within shareholders’ deficit, and are recognized in cost of sales in the condensed consolidated statement of income during the period which approximates the time the hedged inventory is sold. The Company also hedges forecasted intercompany management fees over specific months. These contracts allow the Company to sell Euros in exchange for U.S. dollars at specified contract rates. Changes in the fair value of these forward contracts, excluding forward points, designated as cash flow hedges are recorded as a component of accumulated other comprehensive loss within shareholders’ deficit, and are recognized in selling, general, and administrative expenses within the Company’s condensed consolidated statement of income during the period when the hedged item and underlying transaction affect earnings.

As of September 30, 2019 and December 31, 2018, the aggregate notional amounts of all foreign currency contracts outstanding designated as cash flow hedges were approximately $27.3 million and $43.8 million, respectively. As of September 30, 2019, these outstanding contracts were expected to mature over the next twelve months. The Company’s derivative financial instruments are recorded on the condensed consolidated balance sheets at fair value based on third-party quotes. As of September 30, 2019, the Company recorded assets at fair value of $0.2 million and liabilities at fair value of $0.8 million relating to all outstanding foreign currency contracts designated as cash flow hedges. As of December 31, 2018, the Company recorded assets at fair value of $0.5 million and liabilities at fair value of $0.7 million relating to all outstanding foreign currency contracts designated as cash flow hedges. The Company assesses hedge effectiveness at least quarterly and the hedges remained effective as of September 30, 2019 and December 31, 2018.

As of September 30, 2019 and December 31, 2018, the majority of the Company’s outstanding foreign currency forward contracts had maturity dates of less than twelve months with the majority of freestanding derivatives expiring within one month as of September 30, 2019 and December 31, 2018. As of September 30, 2019, the Company had aggregate notional amounts of approximately $388.0 million of foreign currency contracts, inclusive of freestanding contracts and contracts designated as cash flow hedges.
