commodity prices risk : the company manages commodity price risks through negotiated supply contracts , price protection agreements and forward contracts .3m used commodity price swaps as cash flow hedges of forecasted commodity transactions to manage price volatility , but discontinued this practice in the first quarter of 2015 .the related mark-to-market gain or loss on qualifying hedges was included in other comprehensive income to the extent effective , and reclassified into cost of sales in the period during which the hedged transaction affected earnings .value at risk : the value at risk analysis is performed annually to assess the company 2019s sensitivity to changes in currency rates , interest rates , and commodity prices .a monte carlo simulation technique was used to test the impact on after-tax earnings related to financial instruments ( primarily debt ) , derivatives and underlying exposures outstanding at december 31 , 2015 .the model ( third-party bank dataset ) used a 95 percent confidence level over a 12-month time horizon .the exposure to changes in currency rates model used 18 currencies , interest rates related to three currencies , and commodity prices related to five commodities .this model does not purport to represent what actually will be experienced by the company .this model does not include certain hedge transactions , because the company believes their inclusion would not materially impact the results .the risk of loss or benefit associated with exchange rates was higher in 2015 due to a greater mix of floating rate debt and a rising interest rate environment in the u.s .interest rate volatility increased in 2015 , based on a higher mix of floating rate debt and the use of forward rates .the following table summarizes the possible adverse and positive impacts to after-tax earnings related to these exposures .adverse impact on after-tax positive impact on after-tax earnings earnings .
[['( millions )', 'adverse impact on after-tax earnings 2015', 'adverse impact on after-tax earnings 2014', 'adverse impact on after-tax earnings 2015', '2014'], ['foreign exchange rates', '$ -254 ( 254 )', '$ -164 ( 164 )', '$ 273', '$ 173'], ['interest rates', '-13 ( 13 )', '-4 ( 4 )', '9', '3'], ['commodity prices', '-1 ( 1 )', '-1 ( 1 )', '1', '1']]
in addition to the possible adverse and positive impacts discussed in the preceding table related to foreign exchange rates , recent historical information is as follows .3m estimates that year-on-year currency effects , including hedging impacts , had the following effects on pre-tax income : 2015 ( $ 390 million decrease ) and 2014 ( $ 100 million decrease ) .this estimate includes the effect of translating profits from local currencies into u.s .dollars ; the impact of currency fluctuations on the transfer of goods between 3m operations in the united states and abroad ; and transaction gains and losses , including derivative instruments designed to reduce foreign currency exchange rate risks and the negative impact of swapping venezuelan bolivars into u.s .dollars .3m estimates that year-on-year derivative and other transaction gains and losses had the following effects on pre-tax income : 2015 ( $ 180 million increase ) and 2014 ( $ 10 million increase ) .an analysis of the global exposures related to purchased components and materials is performed at each year-end .a one percent price change would result in a pre-tax cost or savings of approximately $ 70 million per year .the global energy exposure is such that a ten percent price change would result in a pre-tax cost or savings of approximately $ 40 million per year .global energy exposure includes energy costs used in 3m production and other facilities , primarily electricity and natural gas. .
