DERIVATIVE INSTRUMENTS

We enter into derivative instruments designed to mitigate certain risks, including collar contracts to mitigate our risk associated with market fluctuations in diesel fuel prices. These contracts are used strictly to limit our risk exposure and not as speculative transactions. Our derivative instruments associated with diesel fuel do not meet the requirements for cash flow hedge accounting. Therefore, our derivative instruments associated with diesel fuel will be marked-to-market to determine their fair value and the associated gains and losses will be recognized currently in other income (expense) on our consolidated statements of operations.

Our outstanding derivative instrument contracts for the first quarter of 2017 were comprised of the following:
