Fair Value Measurements
Fair Value Measurements
We account for certain assets and liabilities at fair value. We categorize each of our fair value measurements in one of the following three levels based on the lowest level input that is significant to the fair value measurement in its entirety:
Level 1- Inputs to the valuation methodology are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2- Observable inputs other than quoted prices in active markets for identical assets or liabilities include:
a)
quoted prices for similar assets or liabilities in active markets;
b)
quoted prices for identical or similar assets or liabilities in inactive markets;
c)
inputs other than quoted prices that are observable for the asset or liability;
d)
inputs that are derived principally from or corroborated by observable market data by correlation or other means.
If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.
Level 3- Inputs to the valuation methodology are unobservable (i.e., supported by little or no market activity) and significant to the fair value measure.
Assets and Liabilities Measured at Fair Value
As of March 31, 2017 and December 31, 2016, our only assets and liabilities measured at fair value were our fixed price diesel swaps contracts, which are Level 2 derivatives measured at fair value on a recurring basis. As of March 31, 2017 and December 31, 2016, immaterial amounts ($1 or less) were reflected in prepaid expenses and other assets, and accrued expenses and other liabilities in our condensed consolidated balance sheets, reflecting the fair values of the fixed price diesel swaps contracts. As discussed in note 4 to the condensed consolidated financial statements, we entered into the fixed price swap contracts on diesel purchases to mitigate the price risk associated with forecasted purchases of diesel. Fair value is determined based on observable market data. As of March 31, 2017, we have fixed price swap contracts that mature throughout 2017 and 2018 covering 6.0 million gallons of diesel which we will buy at the average contract price of $2.56 per gallon, while the average forward price for the hedged gallons was $2.60 per gallon as of March 31, 2017.
 
Fair Value of Financial Instruments
The carrying amounts reported in our condensed consolidated balance sheets for accounts receivable, accounts payable and accrued expenses and other liabilities approximate fair value due to the immediate to short-term maturity of these financial instruments. The fair values of our senior secured asset-based revolving credit facility (“ABL facility”), accounts receivable securitization facility and capital leases approximated their book values as of March 31, 2017 and December 31, 2016. The estimated fair values of our financial instruments, all of which are categorized in Level 1 of the fair value hierarchy, as of March 31, 2017 and December 31, 2016 have been calculated based upon available market information, and were as follows:
