period .the discount reflects our incremental borrowing rate , which matches the lifetime of the liability .significant changes in the discount rate selected or the estimations of sublease income in the case of leases could impact the amounts recorded .other associated costs with restructuring activities we recognize other costs associated with restructuring activities as they are incurred , including moving costs and consulting and legal fees .pensions we sponsor defined benefit pension plans throughout the world .our most significant plans are located in the u.s. , the u.k. , the netherlands and canada .our significant u.s. , u.k .and canadian pension plans are closed to new entrants .we have ceased crediting future benefits relating to salary and service for our u.s. , u.k .and canadian plans .recognition of gains and losses and prior service certain changes in the value of the obligation and in the value of plan assets , which may occur due to various factors such as changes in the discount rate and actuarial assumptions , actual demographic experience and/or plan asset performance are not immediately recognized in net income .such changes are recognized in other comprehensive income and are amortized into net income as part of the net periodic benefit cost .unrecognized gains and losses that have been deferred in other comprehensive income , as previously described , are amortized into compensation and benefits expense as a component of periodic pension expense based on the average expected future service of active employees for our plans in the netherlands and canada , or the average life expectancy of the u.s .and u.k .plan members .after the effective date of the plan amendments to cease crediting future benefits relating to service , unrecognized gains and losses are also be based on the average life expectancy of members in the canadian plans .we amortize any prior service expense or credits that arise as a result of plan changes over a period consistent with the amortization of gains and losses .as of december 31 , 2013 , our pension plans have deferred losses that have not yet been recognized through income in the consolidated financial statements .we amortize unrecognized actuarial losses outside of a corridor , which is defined as 10% ( 10 % ) of the greater of market-related value of plan assets or projected benefit obligation .to the extent not offset by future gains , incremental amortization as calculated above will continue to affect future pension expense similarly until fully amortized .the following table discloses our combined experience loss , the number of years over which we are amortizing the experience loss , and the estimated 2014 amortization of loss by country ( amounts in millions ) : .
[['', 'u.k .', 'u.s .', 'other'], ['combined experience loss', '$ 2012', '$ 1219', '$ 402'], ['amortization period ( in years )', '29', '26', '11 - 23'], ['estimated 2014 amortization of loss', '$ 53', '$ 44', '$ 10']]
the unrecognized prior service cost at december 31 , 2013 was $ 27 million in the u.k .and other plans .for the u.s .pension plans we use a market-related valuation of assets approach to determine the expected return on assets , which is a component of net periodic benefit cost recognized in the consolidated statements of income .this approach recognizes 20% ( 20 % ) of any gains or losses in the current year's value of market-related assets , with the remaining 80% ( 80 % ) spread over the next four years .as this approach recognizes gains or losses over a five-year period , the future value of assets and therefore , our net periodic benefit cost will be impacted as previously deferred gains or losses are recorded .as of december 31 , 2013 , the market-related value of assets was $ 1.8 billion .we do not use the market-related valuation approach to determine the funded status of the u.s .plans recorded in the consolidated statements of financial position .instead , we record and present the funded status in the consolidated statements of financial position based on the fair value of the plan assets .as of december 31 , 2013 , the fair value of plan assets was $ 1.9 billion .our non-u.s .plans use fair value to determine expected return on assets. .
