Fair Value Financial Instruments And Derivative Insturments |
Derivative Instruments and Hedging Activities Disclosure | Fair Value of Financial Instruments and Derivatives Instruments Cash and cash equivalents and restricted cash and interest rate derivatives are recorded at fair value. The carrying values of the current financial assets and current financial liabilities are reasonable estimates of their fair value due to the short-term nature of these financial instruments. Cash and cash equivalents and restricted cash are considered Level 1 items as they represent liquid assets with short-term maturities. The fair values of the variable interest long-term debt approximate the recorded values, due to their variable interest rates. The fair value of the fixed interest long-term debt is estimated using prevailing market rates as of the period end. The Company believes the terms of its loans are similar to those that could be procured as of December 31, 2018. The fair value of the long-term debt is disclosed in Note 6. Derivative instruments The Company, from time to time, may enter into foreign exchange forward contracts to create economic hedges for its exposure to currency exchange risk on payments relating to acquisition of vessels and on certain loan obligations or for trading purposes. Foreign exchange forward contracts are agreements entered into with a bank to exchange, at a specified future date, currencies of different countries at a specific rate. As of December 31, 2017 and 2018, the Company had no outstanding derivative instruments relating to currency exchange contracts. The Company enters, from time to time, into interest rate swap transactions to manage interest costs and the risk associated with changing interest rates with respect to its variable interest rate loans and credit facilities.The Company’s interest rate swaps did not qualify for hedge accounting. The Company determines the fair market value of the interest rate swaps at the end of every period and accordingly records the resulting unrealized loss/gain during the period in the consolidated statement of operations. As of December 31, 2018 the Company had no outstanding derivative instruments relating to interest rate swaps. Information on the location and amounts of derivative fair values in the consolidated balance sheets and derivative gains/losses in the consolidated statements of operations are shown below: Derivatives not designated as hedging instruments

The gain or loss is recognized in the consolidated statement of operations and is presented in Other (Expense)/Income – (Loss)/gain on derivatives. The Company’s interest rate derivative instruments were pay-fixed, receive-variable interest rate swaps based on the USD LIBOR swap rate. The fair value of the interest rate swaps is determined using a discounted cash flow approach based on market-based LIBOR swap yield curves and take into account the credit risk of the financial institutions that are counterparties in the interest rate swaps. LIBOR swap rates are observable at commonly quoted intervals for the full terms of the swaps and therefore are considered Level 2 items in accordance with the fair value hierarchy. The following table summarizes the valuation of the Company’s financial instruments as of December 31, 2017 and 2018.
