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 ) : .

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. .
