the selection and disclosure of our critical accounting estimates have been discussed with our audit committee . the following is a discussion of the more significant assumptions , estimates , accounting policies and methods used in the preparation of our consolidated financial statements : 2022 revenue recognition - we recognize revenue when persuasive evidence of an arrangement exists , delivery of product has occurred , the sales price is fixed or determinable and collectability is reasonably assured . for our company , this means that revenue is recognized when title and risk of loss is transferred to our customers . title transfers to our customers upon shipment or upon receipt at the customer's location as determined by the sales terms for each transaction . the company estimates the cost of sales returns based on historical experience , and these estimates are normally immaterial . 2022 goodwill and non-amortizable intangible assets valuation - we test goodwill and non-amortizable intangible assets for impairment annually or more frequently if events occur that would warrant such review . we perform our annual impairment analysis in the first quarter of each year . while the company has the option to perform a qualitative assessment for both goodwill and non-amortizable intangible assets to determine if it is more likely than not that an impairment exists , the company elects to perform the quantitative assessment for our annual impairment analysis . the impairment analysis involves comparing the fair value of each reporting unit or non-amortizable intangible asset to the carrying value . if the carrying value exceeds the fair value , goodwill or a non-amortizable intangible asset is considered impaired . to determine the fair value of goodwill , we primarily use a discounted cash flow model , supported by the market approach using earnings multiples of comparable global and local companies within the tobacco industry . at december 31 , 2015 , the carrying value of our goodwill was $ 7.4 billion , which is related to ten reporting units , each of which is comprised of a group of markets with similar economic characteristics . the estimated fair value of our ten reporting units exceeded the carrying value as of december 31 , 2015 . to determine the fair value of non-amortizable intangible assets , we primarily use a discounted cash flow model applying the relief-from-royalty method . we concluded that the fair value of our non-amortizable intangible assets exceeded the carrying value , and any reasonable movement in the assumptions would not result in an impairment . these discounted cash flow models include management assumptions relevant for forecasting operating cash flows , which are subject to changes in business conditions , such as volumes and prices , costs to produce , discount rates and estimated capital needs . management considers historical experience and all available information at the time the fair values are estimated , and we believe these assumptions are consistent with the assumptions a hypothetical marketplace participant would use . since the march 28 , 2008 , spin-off from altria , we have not recorded a charge to earnings for an impairment of goodwill or non-amortizable intangible assets . 2022 marketing and advertising costs - we incur certain costs to support our products through programs which include advertising , marketing , consumer engagement and trade promotions . the costs of our advertising and marketing programs are expensed in accordance with u.s . gaap . recognition of the cost related to our consumer engagement and trade promotion programs contain uncertainties due to the judgment required in estimating the potential performance and compliance for each program . for volume-based incentives provided to customers , management continually assesses and estimates , by customer , the likelihood of the customer achieving the specified targets and records the reduction of revenue as the sales are made . for other trade promotions , management relies on estimated utilization rates that have been developed from historical experience . changes in the assumptions used in estimating the cost of any individual marketing program would not result in a material change in our financial position , results of operations or operating cash flows . we have not made any material changes in the accounting methodology used to estimate our marketing programs during the past three years . 2022 employee benefit plans - as discussed in item 8 , note 13 . benefit plans to our consolidated financial statements , we provide a range of benefits to our employees and retired employees , including pensions , postretirement health care and postemployment benefits ( primarily severance ) . we record annual amounts relating to these plans based on calculations specified by u.s . gaap . these calculations include various actuarial assumptions , such as discount rates , assumed rates of return on plan assets , compensation increases , mortality , turnover rates and health care cost trend rates . we review actuarial assumptions on an annual basis and make modifications to the assumptions based on current rates and trends when it is deemed appropriate to do so . as permitted by u.s . gaap , any effect of the modifications is generally amortized over future periods . we believe that the assumptions utilized in calculating our obligations under these plans are reasonable based upon our historical experience and advice from our actuaries . weighted-average discount rate assumptions for pensions and postretirement plans are as follows: .

Table: 2015 2014 u.s . pension plans 4.30% ( 4.30 % ) 3.95% ( 3.95 % ) non-u.s . pension plans 1.68% ( 1.68 % ) 1.92% ( 1.92 % ) postretirement plans 4.45% ( 4.45 % ) 4.20% ( 4.20 % )

we anticipate that assumption changes , coupled with decreased amortization of deferred losses , will decrease 2016 pre-tax u.s . and non- u.s . pension and postretirement expense to approximately $ 209 million as compared with approximately $ 240 million in 2015 , excluding .

Question: what is the percentage change in the weighted-average discount rate for non-u.s . pension plans from 2014 to 2015?
Answer: -12.5%
Calculation: divide(subtract(1.68, 1.92), 1.92)
