our annual goodwill impairment test from the first quarter to the second quarter . the change was made to more closely align the impairment testing date with our long-range planning and forecasting process . we had determined that this change in accounting principle was preferable under the circumstances and believe that the change in the annual impairment testing date did not delay , accelerate , or avoid an impairment charge . 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 , 2017 , the carrying value of our goodwill was $ 7.7 billion , which is related to ten reporting units , each of which consists of a group of markets with similar economic characteristics . the estimated fair value of each of our ten reporting units exceeded the carrying value as of december 31 , 2017 . 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 . 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 group , inc. , we have not recorded a charge to earnings for an impairment of goodwill or non-amortizable intangible assets . marketing and advertising costs - we incur certain costs to support our products through programs that 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's 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 . 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:
 | 2017 | 2016
pension plans | 1.51% ( 1.51 % ) | 1.52% ( 1.52 % )
postretirement plans | 3.79% ( 3.79 % ) | 3.68% ( 3.68 % )
we anticipate that assumption changes will decrease 2018 pre-tax pension and postretirement expense to approximately $ 164 million as compared with approximately $ 199 million in 2017 , excluding amounts related to early retirement programs .
the anticipated decrease is primarily due to higher expected return on assets of $ 21 million , coupled with lower amortization out of other comprehensive earnings for prior service cost of $ 12 million and unrecognized actuarial gains/losses of $ 10 million , partially offset by other movements of $ 8 million .
weighted-average expected rate of return and discount rate assumptions have a significant effect on the amount of expense reported for the employee benefit plans .
a fifty-basis-point decrease in our discount rate would increase our 2018 pension and postretirement expense by approximately $ 38 million , and a fifty-basis-point increase in our discount rate would decrease our 2018 pension and postretirement expense by approximately $ 54 million .
similarly , a fifty-basis-point decrease ( increase ) in the expected return on plan assets would increase ( decrease ) our 2018 pension expense by approximately $ 45 million .
see item 8 , note 13 .
