what is the ratio of discretionary company contributions to total expensed amounts for savings plans in 2009?

Question: what is that times 100?

Answer: 10.82621


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 track structure expansion ( capacity projects ) and replacement ( program projects ) , which is typically performed by our employees .

approximately 13% ( 13 % ) of our full-time equivalent employees are dedicated to the construction of capital assets .

costs that are directly attributable or overhead costs that relate directly to capital projects 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 .

these costs are allocated using appropriate statistical bases .

the capitalization of indirect costs is consistent with fasb statement no .

67 , accounting for costs and initial rental operations of real estate projects .

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 .

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 .

fair value measurements during the first quarter of 2008 , we fully adopted fasb statement no .

157 , fair value measurements ( fas 157 ) .

fas 157 established a framework for measuring fair value and expanded disclosures about fair value measurements .

the adoption of fas 157 had no impact on our financial position or results of operations .

fas 157 applies to all assets and liabilities that are measured and reported on a fair value basis .

this enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values .

the statement requires that each asset and liability carried at fair value be classified into one of the following categories : level 1 : quoted market prices in active markets for identical assets or liabilities .

level 2 : observable market based inputs or unobservable inputs that are corroborated by market data .

level 3 : unobservable inputs that are not corroborated by market data. .

1	millions of dollars	dec . 31 2008	dec . 31 2007

financial instruments fuel hedges we have entered into multiple swap agreements designated as cash flow hedges to mitigate some of our exposure related to changes in diesel fuel prices .

these swaps qualified for , and were designated as , effective hedges of changes in the prices of forecasted diesel fuel purchases ( fuel hedges ) .

the following table summarizes our outstanding fuel hedges as of december 31 , 2016 : year gallons hedged weighted average contract price per gallon .

on-highway average price for a gallon of diesel fuel as published by the department of energy exceeds the contract price per gallon , we receive the difference between the average price and the contract price ( multiplied by the notional gallons ) from the counterparty .

if the average price is less than the contract price per gallon , we pay the difference to the counterparty .

the fair values of our fuel hedges are determined using standard option valuation models with assumptions about commodity prices based on those observed in underlying markets ( level 2 in the fair value hierarchy ) .

the aggregate fair values of our outstanding fuel hedges as of december 31 , 2016 and 2015 were current liabilities of $ 2.7 million and $ 37.8 million , respectively , and have been recorded in other accrued liabilities in our consolidated balance sheets .

the ineffective portions of the changes in fair values resulted in a gain of $ 0.8 million for the year ended december 31 , 2016 , and a loss of $ 0.4 million and $ 0.5 million for the years ended december 31 , 2015 and 2014 , respectively , and have been recorded in other income , net in our consolidated statements of income .

total gain ( loss ) recognized in other comprehensive income ( loss ) for fuel hedges ( the effective portion ) was $ 20.7 million , $ ( 2.0 ) million and $ ( 24.2 ) million , for the years ended december 31 , 2016 , 2015 and 2014 , respectively .

we classify cash inflows and outflows from our fuel hedges within operating activities in the unaudited consolidated statements of cash flows .

recycling commodity hedges revenue from the sale of recycled commodities is primarily from sales of old corrugated containers and old newsprint .

from time to time we use derivative instruments such as swaps and costless collars designated as cash flow hedges to manage our exposure to changes in prices of these commodities .

during 2016 , we entered into multiple agreements related to the forecasted occ sales .

the agreements qualified for , and were designated as , effective hedges of changes in the prices of certain forecasted recycling commodity sales ( commodity hedges ) .

we entered into costless collar agreements on forecasted sales of occ .

the agreements involve combining a purchased put option giving us the right to sell occ at an established floor strike price with a written call option obligating us to deliver occ at an established cap strike price .

the puts and calls have the same settlement dates , are net settled in cash on such dates and have the same terms to expiration .

the contemporaneous combination of options resulted in no net premium for us and represents costless collars .

under these agreements , we will make or receive no payments as long as the settlement price is between the floor price and cap price ; however , if the settlement price is above the cap , we will pay the counterparty an amount equal to the excess of the settlement price over the cap times the monthly volumes hedged .

if the settlement price is below the floor , the counterparty will pay us the deficit of the settlement price below the floor times the monthly volumes hedged .

the objective of these agreements is to reduce variability of cash flows for forecasted sales of occ between two designated strike prices. .

we have adequate access to capital markets to meet any foreseeable cash requirements , and we have sufficient financial capacity to satisfy our current liabilities .

operating activities higher net income in 2014 increased cash provided by operating activities compared to 2013 , despite higher income tax payments .

2014 income tax payments were higher than 2013 primarily due to higher income , but also because we paid taxes previously deferred by bonus depreciation ( discussed below ) .

higher net income in 2013 increased cash provided by operating activities compared to 2012 .

in addition , we made payments in 2012 for past wages as a result of national labor negotiations , which reduced cash provided by operating activities in 2012 .

lower tax benefits from bonus depreciation ( as discussed below ) partially offset the increases .

federal tax law provided for 100% ( 100 % ) bonus depreciation for qualified investments made during 2011 and 50% ( 50 % ) bonus depreciation for qualified investments made during 2012-2013 .

as a result , the company deferred a substantial portion of its 2011-2013 income tax expense , contributing to the positive operating cash flow in those years .

congress extended 50% ( 50 % ) bonus depreciation for 2014 , but this extension occurred in december and did not have a significant benefit on our income tax payments during 2014 .

investing activities higher capital investments , including the early buyout of the long-term operating lease of our headquarters building for approximately $ 261 million , drove the increase in cash used in investing activities compared to 2013 .

significant investments also were made for new locomotives , freight cars and containers , and capacity and commercial facility projects .

capital investments in 2014 also included $ 99 million for the early buyout of locomotives and freight cars under long-term operating leases , which we exercised due to favorable economic terms and market conditions .

lower capital investments in locomotives and freight cars in 2013 drove the decrease in cash used in investing activities compared to 2012 .

included in capital investments in 2012 was $ 75 million for the early buyout of 165 locomotives under long-term operating and capital leases during the first quarter of 2012 , which we exercised due to favorable economic terms and market conditions. .

the acquisition date is on or after the beginning of the first annual reporting period beginning on or after december 15 , 2008 .

we will evaluate how the new requirements of statement no .

141 ( r ) would impact any business combinations completed in 2009 or thereafter .

in december 2007 , the fasb also issued statement of financial accounting standards no .

160 , noncontrolling interests in consolidated financial statements 2014an amendment of accounting research bulletin no .

a noncontrolling interest , sometimes called a minority interest , is the portion of equity in a subsidiary not attributable , directly or indirectly , to a parent .

160 establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary .

160 , noncontrolling interests in a subsidiary must be reported as a component of consolidated equity separate from the parent 2019s equity .

additionally , the amounts of consolidated net income attributable to both the parent and the noncontrolling interest must be reported separately on the face of the income statement .

160 is effective for fiscal years beginning on or after december 15 , 2008 and earlier adoption is prohibited .

we do not expect the adoption of statement no .

160 to have a material impact on our financial statements and related disclosures .

2008 estimates the forward-looking statements provided in this discussion are based on our examination of historical operating trends , the information that was used to prepare the december 31 , 2007 reserve reports and other data in our possession or available from third parties .

these forward-looking statements were prepared assuming demand , curtailment , producibility and general market conditions for our oil , natural gas and ngls during 2008 will be substantially similar to those of 2007 , unless otherwise noted .

we make reference to the 201cdisclosure regarding forward-looking statements 201d at the beginning of this report .

amounts related to canadian operations have been converted to u.s .

dollars using a projected average 2008 exchange rate of $ 0.98 u.s .

in january 2007 , we announced our intent to divest our west african oil and gas assets and terminate our operations in west africa , including equatorial guinea , cote d 2019ivoire , gabon and other countries in the region .

in november 2007 , we announced an agreement to sell our operations in gabon for $ 205.5 million .

we are finalizing purchase and sales agreements and obtaining the necessary partner and government approvals for the remaining properties in this divestiture package .

we are optimistic we can complete these sales during the first half of 2008 .

all west african related revenues , expenses and capital will be reported as discontinued operations in our 2008 financial statements .

accordingly , all forward-looking estimates in the following discussion exclude amounts related to our operations in west africa , unless otherwise noted .

though we have completed several major property acquisitions and dispositions in recent years , these transactions are opportunity driven .

thus , the following forward-looking estimates do not include any financial and operating effects of potential property acquisitions or divestitures that may occur during 2008 , except for west africa as previously discussed .

oil , gas and ngl production set forth below are our estimates of oil , gas and ngl production for 2008 .

we estimate that our combined 2008 oil , gas and ngl production will total approximately 240 to 247 mmboe .

of this total , approximately 92% ( 92 % ) is estimated to be produced from reserves classified as 201cproved 201d at december 31 , 2007 .

the following estimates for oil , gas and ngl production are calculated at the midpoint of the estimated range for total production .

oil gas ngls total ( mmbbls ) ( bcf ) ( mmbbls ) ( mmboe ) .

2008 estimates the forward-looking statements provided in this discussion are based on our examination of historical operating trends , the information that was used to prepare the december 31 , 2007 reserve reports and other data in our possession or available from third parties .

these forward-looking statements were prepared assuming demand , curtailment , producibility and general market conditions for our oil , natural gas and ngls during 2008 will be substantially similar to those of 2007 , unless otherwise noted .

we make reference to the 201cdisclosure regarding forward-looking statements 201d at the beginning of this report .

amounts related to canadian operations have been converted to u.s .

dollars using a projected average 2008 exchange rate of $ 0.98 u.s .

in january 2007 , we announced our intent to divest our west african oil and gas assets and terminate our operations in west africa , including equatorial guinea , cote d 2019ivoire , gabon and other countries in the region .

in november 2007 , we announced an agreement to sell our operations in gabon for $ 205.5 million .

we are finalizing purchase and sales agreements and obtaining the necessary partner and government approvals for the remaining properties in this divestiture package .

we are optimistic we can complete these sales during the first half of 2008 .

all west african related revenues , expenses and capital will be reported as discontinued operations in our 2008 financial statements .

accordingly , all forward-looking estimates in the following discussion exclude amounts related to our operations in west africa , unless otherwise noted .

though we have completed several major property acquisitions and dispositions in recent years , these transactions are opportunity driven .

thus , the following forward-looking estimates do not include any financial and operating effects of potential property acquisitions or divestitures that may occur during 2008 , except for west africa as previously discussed .

oil , gas and ngl production set forth below are our estimates of oil , gas and ngl production for 2008 .

we estimate that our combined 2008 oil , gas and ngl production will total approximately 240 to 247 mmboe .

of this total , approximately 92% ( 92 % ) is estimated to be produced from reserves classified as 201cproved 201d at december 31 , 2007 .

the following estimates for oil , gas and ngl production are calculated at the midpoint of the estimated range for total production .

oil gas ngls total ( mmbbls ) ( bcf ) ( mmbbls ) ( mmboe ) .

what is the amount of oil and gas mmboe from canada divided by the total?

Question: what is that times 100?

management's financial discussion and analysis net revenue 2008 compared to 2007 net revenue consists of operating revenues net of : 1 ) fuel , fuel-related expenses , and gas purchased for resale , 2 ) purchased power expenses , and 3 ) other regulatory charges .

following is an analysis of the change in net revenue comparing 2008 to 2007 .

the volume/weather variance is due to an increase in electricity usage in the service territory in 2008 compared to the same period in 2007 .

entergy new orleans estimates that approximately 141000 electric customers and 93000 gas customers have returned since hurricane katrina and are taking service as of december 31 , 2008 , compared to approximately 132000 electric customers and 86000 gas customers as of december 31 , 2007 .

billed retail electricity usage increased a total of 184 gwh compared to the same period in 2007 , an increase of 4% ( 4 % ) .

the net gas revenue variance is primarily due to an increase in base rates in march and november 2007 .

refer to note 2 to the financial statements for a discussion of the base rate increase .

the rider revenue variance is due primarily to higher total revenue and a storm reserve rider effective march 2007 as a result of the city council's approval of a settlement agreement in october 2006 .

the approved storm reserve has been set to collect $ 75 million over a ten-year period through the rider and the funds will be held in a restricted escrow account .

the settlement agreement is discussed in note 2 to the financial statements .
