republic services , inc .notes to consolidated financial statements 2014 ( continued ) 16 .financial instruments fuel hedges we have entered into multiple swap agreements designated as cash flow hedges to mitigate some of our exposure related to changes in diesel fuel prices .these swaps qualified for , and were designated as , effective hedges of changes in the prices of forecasted diesel fuel purchases ( fuel hedges ) .the following table summarizes our outstanding fuel hedges as of december 31 , 2015 : year gallons hedged weighted average contract price per gallon .
[['year', 'gallons hedged', 'weighted average contractprice per gallon'], ['2016', '27000000', '$ 3.57'], ['2017', '12000000', '2.92']]
if the national u.s .on-highway average price for a gallon of diesel fuel as published by the department of energy exceeds the contract price per gallon , we receive the difference between the average price and the contract price ( multiplied by the notional gallons ) from the counterparty .if the average price is less than the contract price per gallon , we pay the difference to the counterparty .the fair values of our fuel hedges are determined using standard option valuation models with assumptions about commodity prices based on those observed in underlying markets ( level 2 in the fair value hierarchy ) .the aggregate fair values of our outstanding fuel hedges as of december 31 , 2015 and 2014 were current liabilities of $ 37.8 million and $ 34.4 million , respectively , and have been recorded in other accrued liabilities in our consolidated balance sheets .the ineffective portions of the changes in fair values resulted in a loss of $ 0.4 million and $ 0.5 million for the years ended december 31 , 2015 and 2014 respectively , and a gain of less than $ 0.1 million for the year ended december 31 , 2013 , and have been recorded in other income , net in our consolidated statements of income .total ( loss ) gain recognized in other comprehensive ( loss ) income for fuel hedges ( the effective portion ) was $ ( 2.0 ) million , $ ( 24.2 ) million and $ 2.4 million , for the years ended december 31 , 2015 , 2014 and 2013 , respectively .recycling commodity hedges revenue from the sale of recycled commodities is primarily from sales of old corrugated cardboard and old newspaper .from time to time we use derivative instruments such as swaps and costless collars designated as cash flow hedges to manage our exposure to changes in prices of these commodities .we had no outstanding recycling commodity hedges as of december 31 , 2015 and 2014 .no amounts were recognized in other income , net in our consolidated statements of income for the ineffective portion of the changes in fair values during the years ended december 31 , 2015 , 2014 and 2013 .total gain ( loss ) recognized in other comprehensive income for recycling commodity hedges ( the effective portion ) was $ 0.1 million and $ ( 0.1 ) million for the years ended december 31 , 2014 and 2013 , respectively .no amount was recognized in other comprehensive income for 2015 .fair value measurements in measuring fair values of assets and liabilities , we use valuation techniques that maximize the use of observable inputs ( level 1 ) and minimize the use of unobservable inputs ( level 3 ) .we also use market data or assumptions that we believe market participants would use in pricing an asset or liability , including assumptions about risk when appropriate. .
