Refer to Note (2) of the notes to consolidated financial statements for further detail regarding intangible assets recorded in connection with our acquisition of the Cerner Health Services business.
Non-Operating Items ?
Other income, net was less than $1 million in 2015 and $11 million in 2014.
This decline was primarily due to increased interest expense as a result of the issuance of Senior Notes in January 2015, as further discussed in Note (9) of the notes to consolidated financial statements.
Interest income also declined in 2015 due to lower average investment balances throughout the year.
Refer to Note (11) of the notes to consolidated financial statements for further detail on the composition of other income.  ?
Our effective tax rate was 31% in 2015 compared to 32% in 2014.
The rates include net favorable permanent differences recognized in both periods.
Refer to Note (12) of the notes to consolidated financial statements for further information regarding our effective tax rate.
The research and development credit expired on December 31, 2013, but in the fourth quarter of 2014, was retroactively reinstatedfrom January 1, 2014 to December 31, 2014.
We recognized the research and development tax credit related to 2014 in the fourth quarter of 2014.
In the fourth quarter of 2015, the research and development credit was made permanent for amounts paid or incurred after December 31, 2014.
We recognized the research and development tax credit related to 2015 in the fourth quarter of 2015.
expense for share-based payments, acquisition costs and related adjustments.
The decrease in general and administrative expenses was primarily due to 2016 containing $36 million of expenses associated with a voluntary separation plan.
Refer to Note (1) of the notes to consolidated financial statements for further detail regarding our 2016 voluntary separation plan.  ?
Amortization of acquisition-related intangibles as a percent of total revenues was 2% in both 2017 and 2016.
These expenses remained flat at $91 million in both 2017 and 2016.
Amortization of acquisition-related intangibles includes the amortization of customer relationships, acquired technology, trade names, and non-compete agreements recorded in connection with our business acquisitions.
Non-Operating Items ?
Other income, net remained flat at $7 million in both 2017 and 2016.  ?
Our effective tax rate was 10% in 2017, compared to 31% in 2016.
The decrease in the effective tax rate in 2017 is primarily a result of impacts from certain U. S.  income tax reform enacted in December 2017, and the inclusion of net excess tax benefits as discrete items within the tax provision, upon our adoption of ASU 2016-09 in the first quarter of 2017.
Refer to Note (1) of the notes to consolidated financial statements for further discussion regarding our adoption of ASU 2016-09 and its impact on our consolidated financial statements.
Refer to Note (12) of the notes to consolidated financial statements for further information regarding our effective tax rate.
Our effective tax rate is expected to increase in 2018, from our 2017 rate of 10%.
However, we expect such effective tax rate in 2018 to be lower than historical rates (2016 and prior) primarily due to provisions in the aforementioned U. S.  income tax reform, which reduced the statutory corporate income tax rate from 35% to 21%.

REPUBLIC SERVICES, INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(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, 2013:
## Table 2 ##
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 being 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, 2013 and 2012 were current assets of $6.7 million and $3.1 million, respectively, and current liabilities of $0.1 million and $0.4 million, respectively, and have been recorded in other prepaid expenses and other current assets and other accrued liabilities in our consolidated balance sheets, respectively.
The ineffective portions of the changes in fair values resulted in (losses) gains of less than $0.1 million for the years ended December 31, 2013, 2012 and 2011, and have been recorded in other income (expense), net in our consolidated statements of income.
Total gain (loss) recognized in other comprehensive income for fuel hedges (the effective portion) was $2.4 million, $3.4 million and $(1.7) million, for the years ended December 31, 2013, 2012 and 2011, respectively.
Recycling Commodity Hedges Our revenue from sale of recycling commodities is primarily from sales of old corrugated cardboard (OCC) and old newspaper (ONP).
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 have entered into multiple agreements related to the forecasted OCC and ONP sales.
The agreements qualified for, and were designated as, effective hedges of changes in the prices of certain forecasted recycling commodity sales (commodity hedges).
We entered into costless collar agreements on forecasted sales of OCC and ONP.
The agreements involve combining a purchased put option giving us the right to sell OCC and ONP at an established floor strike price with a written call option obligating us to deliver OCC and ONP at an established cap strike price.
The puts and calls have the same settlement dates, are net settled in cash on such dates and have the same terms to expiration.
The contemporaneous combination of options resulted in no net premium for us and represent costless collars.
Under these agreements, we will make or receive no payments as long as the settlement price is between the floor price and cap price; however, if the settlement price is above the cap, we will pay the counterparty an amount equal to the excess of the settlement price over the cap times the monthly volumes hedged.
If the settlement price
