Other Financial Instruments

The company’s primary financial instruments consist of cash and cash equivalents, trade receivables and trade payables with book values that are considered to be representative of their respective fair values. The company periodically utilizes derivative financial instruments to hedge against foreign currency denominated assets and liabilities, currency commitments, or to lock in desired interest rates. These transactions are generally spot or forward currency contracts or interest rate swaps that are entered into with major financial institutions. Derivative financial instruments are intended to

reduce the company’s exposure to foreign currency exchange risk and interest rate risk. The company enters into derivative instruments only to the extent considered necessary to address its risk management objectives and does not use derivative contracts for speculative purposes. The derivative instruments are recorded at fair value using quoted prices and quotes obtainable from the counterparties to the derivative instruments.

Cash Equivalents. The company’s cash equivalents, which are securities with maturities less than 90 days, are held in money market funds or time deposit accounts with highly rated financial institutions. The carrying value for cash equivalents is considered to be representative of its fair value due to the short duration and conservative nature of the cash equivalent investment portfolio.

Spot Derivatives. Spot derivative financial instruments are short-term in nature and generally settle within two business days. The fair value of spot derivatives approximates the carrying value due to the short-term nature of this instrument, and as a result, no gains or losses are recognized.

The company had no outstanding spot contracts at December 31, 2015. The company had two foreign exchange spot contracts outstanding at March 31, 2015, which had a notional value of $2.3 million and settled by April 1, 2015.

Forward Derivatives. Forward derivative financial instruments are usually longer-term in nature but generally do not exceed one year. The accounting for gains or losses on forward contracts is dependent on the nature of the risk being hedged and the effectiveness of the hedge. Forward contracts are valued using counterparty quotations, and we validate the information obtained from the counterparties in calculating the ultimate fair values using the market approach and obtaining broker quotations. As such, these derivative contracts are classified as Level 2.

At December 31, 2015, the company had 14 Norwegian kroner (NOK) forward contracts outstanding, which are generally intended to hedge the company’s foreign exchange exposure relating to its NOK denominated notes payable as disclosed in Note (5). The forward contracts have expiration dates between January 2016 and November 2016. The combined change in fair value of the forward contracts was $1.8 million, all of which was recorded as a foreign exchange loss during the nine months ended December 31, 2015, because the forward contracts did not qualify as hedge instruments. All changes in fair value of the forward contracts were recorded in earnings. The company did not have any forward contracts outstanding at March 31, 2015.
