Question:
what percent of total material obligations and commitments as of december 31 , 2009 are operating leases?


pre_text: payables that were reclassified as part of our capital lease obligations .
capital lease obligations are reported in our consolidated statements of financial position as debt .
on october 15 , 2009 , we entered into a capital lease agreement for 44 locomotives with a total equipment cost of $ 100 million .
the lessor purchased the 44 locomotives from the corporation and subsequently leased the locomotives back to the railroad .
these capital lease obligations are reported in our consolidated statements of financial position as debt at december 31 , 2009 .
off-balance sheet arrangements , contractual obligations , and commercial commitments as described in the notes to the consolidated financial statements and as referenced in the tables below , we have contractual obligations and commercial commitments that may affect our financial condition .
based on our assessment of the underlying provisions and circumstances of our contractual obligations and commercial commitments , including material sources of off-balance sheet and structured finance arrangements , other than the risks that we and other similarly situated companies face with respect to the condition of the capital markets ( as described in item 1a of part ii of this report ) , there is no known trend , demand , commitment , event , or uncertainty that is reasonably likely to occur that would have a material adverse effect on our consolidated results of operations , financial condition , or liquidity .
in addition , our commercial obligations , financings , and commitments are customary transactions that are similar to those of other comparable corporations , particularly within the transportation industry .
the following tables identify material obligations and commitments as of december 31 , 2009 : payments due by december 31 , contractual obligations after millions of dollars total 2010 2011 2012 2013 2014 2014 other .
post_text: [a] excludes capital lease obligations of $ 2061 million , unamortized discount of $ ( 110 ) million , and market value adjustments of $ 15 million for debt with qualifying hedges that are recorded as liabilities on the consolidated statements of financial position .
includes an interest component of $ 4763 million .
[b] represents total obligations , including interest component of $ 914 million .
[c] purchase obligations include locomotive maintenance contracts ; purchase commitments for ties , ballast , and rail ; and agreements to purchase other goods and services .
for amounts where we can not reasonably estimate the year of settlement , they are reflected in the other column .
[d] includes estimated other post retirement , medical , and life insurance payments and payments made under the unfunded pension plan for the next ten years .
no amounts are included for funded pension as no contributions are currently required .
[e] future cash flows for income tax contingencies reflect the recorded liability for unrecognized tax benefits , including interest and penalties , as of december 31 , 2009 .
where we can reasonably estimate the years in which these liabilities may be settled , this is shown in the table .
for amounts where we can not reasonably estimate the year of settlement , they are reflected in the other column. .
