contingent consideration of up to $ 13.8 million .
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 .

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 .

while net earnings were flat in 2003 compared with 2002 , the lower earnings per share amount in 2003 as compared with 2002 reflected the full-year impact of our stock offering in may 2002 .
our individual segment performance will be discussed later in this section .
our working capital , excluding short-term debt , was $ 339.8 million at december 31 , 2004 , compared with $ 305.9 million and $ 225.1 million at december 31 , 2003 , and december 31 , 2002 , respectively .
the $ 33.9 million increase in 2004 reflects $ 44.9 million higher receivable balances due to longer payment terms experienced by both of our businesses as well as higher sales levels in the fourth quarter .
offsetting the increase in receivable balances were $ 13.5 million lower inventory levels split about equally between water systems and electrical products and $ 14.3 million higher accounts payable balances .
the $ 80.8 million increase in 2003 reflects $ 46.6 million higher inventory balances due primarily to extensive manufacturing repositioning in our electric motor business and several new product introductions and manufacturing consolidation in our water systems business .
additionally , receivable balances were $ 21.2 million higher due to price increases associated with new product introductions in our water systems business and an increase in international sales , which tend to have longer payment terms .
finally , a $ 13.1 million increase in accounts payable balances was largely offset by $ 9.4 million in restructuring expenses paid out in 2003 .
reducing working capital is one of our major initiatives in 2005 .
cash provided by operating activities during 2004 was $ 67.2 million compared with $ 29.0 million during 2003 and $ 116.0 million during 2002 .
despite lower earnings in 2004 , a smaller investment in working capital explains the majority of the improvement in cash flow compared with 2003 .
the higher investment in working capital in 2003 ( as discussed above ) , explains the majority of the difference between 2003 and our capital expenditures were $ 48.5 million in 2004 , essentially the same as in 2003 and approximately $ 2.2 million higher than in 2002 .
the increase in 2003 was associated with new product launches in our water systems business .
we are projecting 2005 capital expenditures to be approximately $ 55 million , essentially the same as our projected 2005 depreciation expense .
we believe that our present facilities and planned capital expenditures are sufficient to provide adequate capacity for our operations in 2005 .
in june 2004 , we completed a $ 265 million , five-year revolving credit facility with a group of eight banks .
the new facility expires on june 10 , 2009 , and it replaced a $ 250 million credit facility which expired on august 2 , 2004 , and was terminated on june 10 , 2004 .
the new facility backs up commercial paper and credit line borrowings .
as a result of the long-term nature of this facility , the commercial paper and credit line borrowings are now classified as long-term debt .
at december 31 , 2004 , we had available borrowing capacity of $ 153.9 million under this facility .
we believe that the combination of available borrowing capacity and operating cash flow will provide sufficient funds to finance our existing operations for the foreseeable future .
to take advantage of historically low long-term borrowing rates , we issued $ 50.0 million in senior notes with two insurance companies in june 2003 .
the notes range in maturity between 2013 and 2016 and carry a weighted average interest rate of slightly less than 4.5 percent .
the proceeds of the notes were used to repay commercial paper and borrowing under the credit facility .
our leverage , as measured by the ratio of total debt to total capitalization , was 32 percent at the end of 2004 and the end of 2003 .
aggregate contractual obligations a summary of our contractual obligations as of december 31 , 2004 , is as follows: .

( a ) effective in 2016 , the company began to measure the service cost and interest cost components of pension expense by applying spot rates along the yield curve to the relevant projected cash flows , as we believe this provides a better measurement of these costs .

this change does not affect the measurement of the total benefit obligation .
2016 vs .
2015 pension expense , excluding special items , decreased from the prior year due to the adoption of the spot rate approach which reduced service cost and interest cost , the impact from expected return on assets and demographic gains , partially offset by the impact of the adoption of new mortality tables for our major plans .
special items of $ 7.3 included pension settlement losses of $ 6.4 , special termination benefits of $ 2.0 , and curtailment gains of $ 1.1 .
these resulted primarily from our recent business restructuring and cost reduction actions .
2015 vs .
2014 the decrease in pension expense , excluding special items , was due to the impact from expected return on assets , a 40 bp reduction in the weighted average compensation increase assumption , and lower service cost and interest cost .

pension settlement losses of $ 10 to $ 15 are expected , dependent on the timing of retirements .
in 2017 , we expect pension expense to include approximately $ 164 for amortization of actuarial losses compared to $ 121 in 2016 .

approximately $ 237.8 million of the spectrasite valuation allowance was assumed as of the acquisition date .
the balance of the valuation allowance primarily relates to net state deferred tax assets .
the company has not provided a valuation allowance for the remaining deferred tax assets , primarily its federal net operating loss carryforwards , as management believes the company will have sufficient time to realize these federal net operating loss carryforwards during the twenty-year tax carryforward period .
the company intends to recover a portion of its deferred tax asset through its federal income tax refund claims related to the carry back of certain federal net operating losses .
in june 2003 and october 2003 , the company filed federal income tax refund claims with the irs relating to the carry back of $ 380.0 million of net operating losses generated prior to 2003 , of which the company initially anticipated receiving approximately $ 90.0 million .
based on preliminary discussions with tax authorities , the company has revised its estimate of the net realizable value of the federal income tax refund claims and anticipates receiving a refund of approximately $ 65.0 million as a result of these claims by the end of 2006 .
there can be no assurances , however , with respect to the specific amount and timing of any refund .
the recoverability of the company 2019s remaining net deferred tax asset has been assessed utilizing stable state ( no growth ) projections based on its current operations .
the projections show a significant decrease in depreciation and interest expense in the later years of the carryforward period as a result of a significant portion of its assets being fully depreciated during the first fifteen years of the carryforward period and debt repayments reducing interest expense .
accordingly , the recoverability of the net deferred tax asset is not dependent on material improvements to operations , material asset sales or other non-routine transactions .
based on its current outlook of future taxable income during the carryforward period , management believes that the net deferred tax asset will be realized .
the realization of the company 2019s deferred tax assets as of december 31 , 2005 will be dependent upon its ability to generate approximately $ 1.3 billion in taxable income from january 1 , 2006 to december 31 , 2025 .
if the company is unable to generate sufficient taxable income in the future , or carry back losses , as described above , it will be required to reduce its net deferred tax asset through a charge to income tax expense , which would result in a corresponding decrease in stockholders 2019 equity .
from time to time the company is subject to examination by various tax authorities in jurisdictions in which the company has significant business operations .

2016 outlook f0b7 safety 2013 operating a safe railroad benefits all our constituents : our employees , customers , shareholders and the communities we serve .
we will continue using a multi-faceted approach to safety , utilizing technology , risk assessment , quality control , training and employee engagement , and targeted capital investments .
we will continue using and expanding the deployment of total safety culture and courage to care throughout our operations , which allows us to identify and implement best practices for employee and operational safety .
we will continue our efforts to increase detection of rail defects ; improve or close crossings ; and educate the public and law enforcement agencies about crossing safety through a combination of our own programs ( including risk assessment strategies ) , industry programs and local community activities across our network .
f0b7 network operations 2013 in 2016 , we will continue to align resources with customer demand , continue to improve network performance , and maintain our surge capability .
f0b7 fuel prices 2013 with the dramatic drop in fuel prices during 2015 , fuel price projections continue to be uncertain in the current environment .
we again could see volatile fuel prices during the year , as they are sensitive to global and u.s .
domestic demand , refining capacity , geopolitical events , weather conditions and other factors .
as prices fluctuate , there will be a timing impact on earnings , as our fuel surcharge programs trail fluctuations in fuel price by approximately two months .
continuing lower fuel prices could have a positive impact on the economy by increasing consumer discretionary spending that potentially could increase demand for various consumer products that we transport .
alternatively , lower fuel prices will likely have a negative impact on other commodities such as coal , frac sand and crude oil shipments .
f0b7 capital plan 2013 in 2016 , we expect our capital plan to be approximately $ 3.75 billion , including expenditures for ptc , 230 locomotives and 450 freight cars .
the capital plan may be revised if business conditions warrant or if new laws or regulations affect our ability to generate sufficient returns on these investments .
( see further discussion in this item 7 under liquidity and capital resources 2013 capital plan. ) f0b7 financial expectations 2013 economic conditions in many of our market sectors continue to drive uncertainty with respect to our volume levels .
we expect volumes to be down slightly in 2016 compared to 2015 , but will depend on the overall economy and market conditions .
the strong u.s .
dollar and historic low commodity prices could also drive continued volatility .
one of the biggest uncertainties is the outlook for energy markets , which will bring both challenges and opportunities .
in the current environment , we expect continued margin improvement driven by continued pricing opportunities , ongoing productivity initiatives , and the ability to leverage our resources and strengthen our franchise .
over the longer term , we expect the overall u.s .
economy to continue to improve at a modest pace , with some markets outperforming others. .

2016 outlook f0b7 safety 2013 operating a safe railroad benefits all our constituents : our employees , customers , shareholders and the communities we serve .
we will continue using a multi-faceted approach to safety , utilizing technology , risk assessment , quality control , training and employee engagement , and targeted capital investments .
we will continue using and expanding the deployment of total safety culture and courage to care throughout our operations , which allows us to identify and implement best practices for employee and operational safety .
we will continue our efforts to increase detection of rail defects ; improve or close crossings ; and educate the public and law enforcement agencies about crossing safety through a combination of our own programs ( including risk assessment strategies ) , industry programs and local community activities across our network .
f0b7 network operations 2013 in 2016 , we will continue to align resources with customer demand , continue to improve network performance , and maintain our surge capability .
f0b7 fuel prices 2013 with the dramatic drop in fuel prices during 2015 , fuel price projections continue to be uncertain in the current environment .
we again could see volatile fuel prices during the year , as they are sensitive to global and u.s .
domestic demand , refining capacity , geopolitical events , weather conditions and other factors .
as prices fluctuate , there will be a timing impact on earnings , as our fuel surcharge programs trail fluctuations in fuel price by approximately two months .
continuing lower fuel prices could have a positive impact on the economy by increasing consumer discretionary spending that potentially could increase demand for various consumer products that we transport .
alternatively , lower fuel prices will likely have a negative impact on other commodities such as coal , frac sand and crude oil shipments .
f0b7 capital plan 2013 in 2016 , we expect our capital plan to be approximately $ 3.75 billion , including expenditures for ptc , 230 locomotives and 450 freight cars .
the capital plan may be revised if business conditions warrant or if new laws or regulations affect our ability to generate sufficient returns on these investments .
( see further discussion in this item 7 under liquidity and capital resources 2013 capital plan. ) f0b7 financial expectations 2013 economic conditions in many of our market sectors continue to drive uncertainty with respect to our volume levels .
we expect volumes to be down slightly in 2016 compared to 2015 , but will depend on the overall economy and market conditions .
the strong u.s .
dollar and historic low commodity prices could also drive continued volatility .
one of the biggest uncertainties is the outlook for energy markets , which will bring both challenges and opportunities .
in the current environment , we expect continued margin improvement driven by continued pricing opportunities , ongoing productivity initiatives , and the ability to leverage our resources and strengthen our franchise .
over the longer term , we expect the overall u.s .
economy to continue to improve at a modest pace , with some markets outperforming others. .
