the decline in the remaining after-tax unrealized loss amounts related to transferred securities resulted from amortization and from the recognition of losses from other-than-temporary impairment on certain of the securities .
we conduct periodic reviews of individual securities to assess whether other-than-temporary impairment exists .
to the extent that other-than-temporary impairment is identified , the impairment is broken into a credit component and a non-credit component .
the credit component is recognized in our consolidated statement of income , and the non-credit component is recognized in other comprehensive income to the extent that management does not intend to sell the security ( see note 3 of the notes to consolidated financial statements included under item 8 ) .
the assessment of other-than-temporary impairment involves an evaluation of economic and security- specific factors , which are more fully described in note 3 .
such factors are based upon estimates , derived by management , which contemplate current market conditions and security-specific performance .
to the extent that market conditions are worse than management 2019s expectations , other-than-temporary impairment could increase , in particular the credit component that would be recognized in our consolidated statement of income .
national housing prices , according to the case-shiller national hpi , have declined to date approximately 30% ( 30 % ) peak-to-current .
management currently estimates that national housing prices will continue to decline and bottom out during the second half of 2010 , consistent with a peak-to-trough housing price decline of approximately 37% ( 37 % ) .
as an indication of the sensitivity of our portfolio with respect to our more significant assumptions underlying our assessment of impairment , if we were to increase our default estimates to 110% ( 110 % ) of management 2019s current expectations with a corresponding slowing of prepayment speeds to 90% ( 90 % ) of management 2019s current expectations , credit-related other-than-temporary impairment could increase by approximately $ 120 million to $ 125 million , which impairment would be recorded in our consolidated statement of income .
excluding the securities for which other-than-temporary impairment was recorded , management considers the aggregate decline in fair value of the remaining securities and the resulting net unrealized losses to be temporary and not the result of any material changes in the credit characteristics of the securities .
additional information about our assessment of impairment is provided in note 3 of the notes to consolidated financial statements included under item 8. .

the contingent consideration arrangement requires additional cash payments to the former equity holders of lyric upon the achievement of certain technological and product development milestones payable during the period from june 2011 through june 2016 .
the company estimated the fair value of the contingent consideration arrangement utilizing the income approach .
changes in the fair value of the contingent consideration subsequent to the acquisition date primarily driven by assumptions pertaining to the achievement of the defined milestones will be recognized in operating income in the period of the estimated fair value change .
as of october 29 , 2011 , no contingent payments have been made and the fair value of the contingent consideration was approximately $ 14.0 million .
the company allocated the purchase price to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition , resulting in the recognition of $ 12.2 million of ipr&d , $ 18.9 million of goodwill and $ 3.3 million of net deferred tax liabilities .

the analysis of our depreciation studies .
changes in the estimated service lives of our assets and their related depreciation rates are implemented prospectively .
under group depreciation , the historical cost ( net of salvage ) of depreciable property that is retired or replaced in the ordinary course of business is charged to accumulated depreciation and no gain or loss is recognized .
the historical cost of certain track assets is estimated using ( i ) inflation indices published by the bureau of labor statistics and ( ii ) the estimated useful lives of the assets as determined by our depreciation studies .
the indices were selected because they closely correlate with the major costs of the properties comprising the applicable track asset classes .
because of the number of estimates inherent in the depreciation and retirement processes and because it is impossible to precisely estimate each of these variables until a group of property is completely retired , we continually monitor the estimated service lives of our assets and the accumulated depreciation associated with each asset class to ensure our depreciation rates are appropriate .
in addition , we determine if the recorded amount of accumulated depreciation is deficient ( or in excess ) of the amount indicated by our depreciation studies .
any deficiency ( or excess ) is amortized as a component of depreciation expense over the remaining service lives of the applicable classes of assets .
for retirements of depreciable railroad properties that do not occur in the normal course of business , a gain or loss may be recognized if the retirement meets each of the following three conditions : ( i ) is unusual , ( ii ) is material in amount , and ( iii ) varies significantly from the retirement profile identified through our depreciation studies .
a gain or loss is recognized in other income when we sell land or dispose of assets that are not part of our railroad operations .
when we purchase an asset , we capitalize all costs necessary to make the asset ready for its intended use .
however , many of our assets are self-constructed .
a large portion of our capital expenditures is for replacement of existing track assets and other road properties , which is typically performed by our employees , and for track line expansion and other capacity projects .
costs that are directly attributable to capital projects ( including overhead costs ) are capitalized .
direct costs that are capitalized as part of self- constructed assets include material , labor , and work equipment .
indirect costs are capitalized if they clearly relate to the construction of the asset .
general and administrative expenditures are expensed as incurred .
normal repairs and maintenance are also expensed as incurred , while costs incurred that extend the useful life of an asset , improve the safety of our operations or improve operating efficiency are capitalized .
these costs are allocated using appropriate statistical bases .
total expense for repairs and maintenance incurred was $ 2.4 billion for 2014 , $ 2.3 billion for 2013 , and $ 2.1 billion for 2012 .
assets held under capital leases are recorded at the lower of the net present value of the minimum lease payments or the fair value of the leased asset at the inception of the lease .

Current question:
so what is the percentage change during this time?

Dialogue history:
[Turn 1] what was the difference in the total expense for repairs and maintenance incurred between 2013 and 2014?
[Turn 2] and the value for 2013 again?
[Turn 3] so what is the percentage change during this time?

the analysis of our depreciation studies .
changes in the estimated service lives of our assets and their related depreciation rates are implemented prospectively .
under group depreciation , the historical cost ( net of salvage ) of depreciable property that is retired or replaced in the ordinary course of business is charged to accumulated depreciation and no gain or loss is recognized .
the historical cost of certain track assets is estimated using ( i ) inflation indices published by the bureau of labor statistics and ( ii ) the estimated useful lives of the assets as determined by our depreciation studies .
the indices were selected because they closely correlate with the major costs of the properties comprising the applicable track asset classes .
because of the number of estimates inherent in the depreciation and retirement processes and because it is impossible to precisely estimate each of these variables until a group of property is completely retired , we continually monitor the estimated service lives of our assets and the accumulated depreciation associated with each asset class to ensure our depreciation rates are appropriate .
in addition , we determine if the recorded amount of accumulated depreciation is deficient ( or in excess ) of the amount indicated by our depreciation studies .
any deficiency ( or excess ) is amortized as a component of depreciation expense over the remaining service lives of the applicable classes of assets .
for retirements of depreciable railroad properties that do not occur in the normal course of business , a gain or loss may be recognized if the retirement meets each of the following three conditions : ( i ) is unusual , ( ii ) is material in amount , and ( iii ) varies significantly from the retirement profile identified through our depreciation studies .
a gain or loss is recognized in other income when we sell land or dispose of assets that are not part of our railroad operations .
when we purchase an asset , we capitalize all costs necessary to make the asset ready for its intended use .
however , many of our assets are self-constructed .
a large portion of our capital expenditures is for replacement of existing track assets and other road properties , which is typically performed by our employees , and for track line expansion and other capacity projects .
costs that are directly attributable to capital projects ( including overhead costs ) are capitalized .
direct costs that are capitalized as part of self- constructed assets include material , labor , and work equipment .
indirect costs are capitalized if they clearly relate to the construction of the asset .
general and administrative expenditures are expensed as incurred .
normal repairs and maintenance are also expensed as incurred , while costs incurred that extend the useful life of an asset , improve the safety of our operations or improve operating efficiency are capitalized .
these costs are allocated using appropriate statistical bases .
total expense for repairs and maintenance incurred was $ 2.4 billion for 2014 , $ 2.3 billion for 2013 , and $ 2.1 billion for 2012 .
assets held under capital leases are recorded at the lower of the net present value of the minimum lease payments or the fair value of the leased asset at the inception of the lease .
amortization expense is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease .
