Fair Value Measurements
Fair Value Measurements
We account for certain assets and liabilities at fair value, and 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 and 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
Our fixed price diesel swap contracts are Level 2 derivatives measured at fair value on a recurring basis. As of December 31, 2015 and 2014, immaterial amounts ($6 or less) were reflected in prepaid expenses and other assets, and accrued expenses and other liabilities in our consolidated balance sheets, reflecting the fair values of the fixed price swap contracts. As discussed in note 10 to the 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 December 31, 2015, we have fixed price swap contracts covering 10.3 million gallons of diesel which we will buy throughout 2016 and 2017 at the average contract price of $2.93 per gallon, while the average forward price for the hedged gallons was $2.35 per gallon as of December 31, 2015.
The fair value of the contingent cash consideration component of the National Pump purchase price discussed in note 3 to our consolidated financial statements was $0 as of December 31, 2015 and $78 as of December 31, 2014. In June 2015, we paid the contingent consideration and were relieved of further liabilities associated therewith. The contingent consideration was recorded in accrued expenses and other liabilities in our condensed consolidated balance sheets, and was a Level 3 liability that was measured at fair value on a recurring basis. Fair value was determined using a probability weighted discounted cash flow methodology. Key inputs to the valuation included: (i) discrete scenarios of potential payouts; (ii) probability weightings assigned to each of the scenarios; and (iii) a rate of return with which to discount the probability weighted payouts to present value. Changes to the fair value of the contingent cash consideration are reflected in our consolidated statements of income as “Merger related costs” which included a $26 fair value reduction for the year ended December 31, 2015. In June 2015, we paid the liability remaining after recognizing the decline in fair value, and were relieved of further liabilities associated therewith. The decline in the fair value of the contingent cash consideration primarily related to lower than expected financial performance compared to agreed upon financial targets.
Fair Value of Financial Instruments
The carrying amounts reported in our 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”) and accounts receivable securitization facility approximate their book values as of December 31, 2015 and 2014. The estimated fair values of our other financial instruments at December 31, 2015 and 2014 have been calculated based upon available market information or an appropriate valuation technique, and are as follows:

(1)
The fair value of the 4 percent Convertible Senior Notes is based on the market value of comparable notes. Consistent with the carrying amount, the fair value excludes the equity component of the notes. The 4 percent Convertible Senior Notes matured in 2015. To exclude the equity component and calculate the fair value as of December 31, 2014, we used an effective interest rate of 7.3 percent.
(2)
The fair value of capital leases reflects the present value of the leases using a 7.0 percent interest rate.
