for more information about our sources of funding , see “ credit facility ” and “ liquidity and capital resources . ” full scale development and launch services agreements in june 2010 , we executed a primarily fixed price full scale development contract , or fsd , with thales alenia space france , or thales , for the design and manufacture of satellites for iridium next . the total price under the fsd will be approximately $ 2.3 billion , and we expect our payment obligations under the fsd to extend into the first quarter of 2018. as of december 31 , 2014 , we had made total payments of $ 1,331.1 million to thales , of which $ 1,129.8 million were from borrowings under the credit facility , which are classified within property and equipment , net , in our consolidated balance sheet included in this report . we currently use the credit facility to pay 85 % of each invoice received from thales under the fsd with the remaining 15 % funded from cash on hand . once the credit facility is fully drawn , we expect to pay 100 % of each invoice received from thales from cash and marketable securities on hand as well as internally generated cash flows , including potential cash flows from hosted payloads and iridium prime . in march 2010 , we entered into an agreement with space exploration technologies corp. , or spacex , to secure spacex as the primary launch services provider for iridium next . the total price under the spacex agreement for seven launches is $ 453.1 million . as of december 31 , 2014 , we had made aggregate payments of $ 152.6 million to spacex , which were capitalized as construction in progress within property and equipment , net . in addition , we made a $ 3.0 million refundable deposit to spacex in the first quarter of 2014 for the reservation of additional future launches , which amount is not included in the total contract price . 39 in june 2011 , we entered into an agreement with international space company kosmotras , or kosmotras , as a supplemental launch services provider for iridium next . the kosmotras agreement originally provided for the purchase of up to six launches with options to purchase additional launches . each launch can carry two satellites . in june 2013 , we exercised an option for one launch to carry the first two iridium next satellites . if we do not exercise any additional options , the total cost under the kosmotras agreement including this single launch will be $ 51.8 million . as of december 31 , 2014 , we had made aggregate payments of $ 28.8 million to kosmotras , which were capitalized as construction in process within property and equipment , net . the option to purchase two of the dedicated launches expired as of december 31 , 2013. we have agreed with kosmotras to extend the option to purchase the remaining three dedicated launches through a date to be determined . credit facility on october 4 , 2010 , we entered into the credit facility with a syndicate of bank lenders . ninety-five percent of our obligations under the credit facility are insured by compagnie française d'assurance pour le commerce extérieur , or coface . the credit facility consists of two tranches , with draws and repayments applied pro rata in respect of each tranche : tranche a – $ 1,537,500,000 at a fixed rate of 4.96 % ; and tranche b – $ 262,500,000 at a floating rate equal to the london interbank offer rate , or libor , plus 1.95 % . in connection with each draw made under the credit facility , we borrow an additional amount equal to 6.49 % of such draw to cover the premium for the coface insurance . we also pay a commitment fee of 0.80 % per year , in semi-annual installments , on any undrawn portion of the credit facility . the semi-annual commitment fee on the undrawn portion of the credit facility for the year ended december 31 , 2014 was $ 5.8 million and is included in other income ( expense ) in our consolidated statement of operations . funds drawn under the credit facility are used to pay 85 % of each invoice issued by thales under the fsd until the credit facility is fully drawn , the premium for the coface insurance and the payment of a portion of interest during a portion of the construction and launch phase of iridium next . scheduled semi-annual principal repayments will begin six months after the earlier of ( i ) the successful deployment of a specified number of iridium next satellites or ( ii ) september 30 , 2017. during this repayment period , we will pay interest on the same date as the principal repayments . prior to the repayment period , interest payments are due on a semi-annual basis in april and october . interest incurred during the year ended december 31 , 2014 was $ 50.8 million . we capitalize all interest costs incurred related to the credit facility during the construction period of the assets ; accordingly we capitalized $ 50.8 million related to interest incurred in 2014. we pay interest on each semi-annual due date through a combination of a cash payment and a deemed additional loan . the $ 50.8 million in interest incurred during the year ended december 31 , 2014 consisted of $ 15.5 million payable in cash , of which $ 12.6 million was paid during the year and $ 2.9 million was accrued at year end , and $ 35.3 million payable by deemed loans , of which $ 28.6 million was paid during the year and $ 6.7 million was accrued at year end . the credit facility will mature seven years after the start of the principal repayment period . story_separator_special_tag the selling price used for each deliverable is based on vendor-specific objective evidence when available , third-party evidence when vendor-specific evidence is not available , or the estimated selling price when neither vendor-specific evidence nor third-party evidence is available . we determine vendor-specific objective evidence of selling price by assessing sales prices of subscriber equipment , airtime and other services when they are sold to customers on a stand-alone basis . our determination of best estimate of selling price is consistent with our determination of vendor-specific objective evidence of selling price and we assess qualitative and quantitative market factors and entity-specific factors when estimating the selling price . we recognize revenue for each element based on the specific characteristics of that element . 43 we sell prepaid services in the form of e-vouchers and prepaid cards . a liability is established equal to the cash paid upon purchase for the e-voucher or prepaid card . we recognize revenue from the prepaid services upon the use of the e-voucher or prepaid card by the customer ; or upon the expiration of the right to access the prepaid service . in september 2012 , we communicated a new expiration policy with respect to prepaid e-vouchers , effective december 2013. while the terms of prepaid e-vouchers can be extended by the purchase of additional e-vouchers , prepaid e-vouchers may not be extended beyond the new limits of three or four years , dependent on the initial expiry period when purchased . we do not offer refunds for unused prepaid services . revenue associated with some of our fixed-price engineering services arrangements is recognized when the services are rendered , typically on a partial performance method of accounting based on our estimate of total costs expected to complete the contract , and the related costs are expensed as incurred . we recognize revenue on cost-plus-fixed-fee arrangements to the extent of actual costs incurred plus an estimate of the applicable fees earned , where such estimated fees are determined using a partial performance method calculation . if actual results are not consistent with our estimates or assumptions , we may be exposed to changes to earned and unearned revenue that could be material to our results of operations . stock-based compensation we account for stock-based compensation , which consists of stock options and restricted stock units , based on the grant date estimated fair value . in the case of restricted stock units , grant date fair value is equal to the closing price of our common stock on the date of grant . the expected vesting of our performance-based rsus is based upon the likelihood that we achieve the defined performance goals . the level of achievement of performance goals , if any , is determined by the compensation committee . in the case of stock options , grant date fair value is calculated using the black-scholes option pricing model . we recognize stock-based compensation on a straight-line basis over the requisite service period . the black-scholes option pricing model requires us to make several assumptions , including expected volatility and expected term of the options . if any of the assumptions we use in the black-scholes option pricing model were to change significantly , stock-based compensation expense may differ materially in the future from that recorded in the current period . in addition , we are required to estimate the expected forfeiture rate and only recognize expense for those awards expected to vest . we estimate the forfeiture rate based on historical experience . to the extent our actual forfeiture rate is different from our estimate , stock-based compensation expense is adjusted accordingly . warranty expenses we estimate a provision for product returns under our standard warranty policies when it is probable that a loss has been incurred . a warranty liability is maintained based on historical experience of warranty costs and expected occurrences of warranty claims on equipment . if actual results are not consistent with our estimates or assumptions , we may be exposed to changes to cost of subscriber equipment sales that could be material to our results of operations . income taxes we account for income taxes using the asset and liability approach . this approach requires that we recognize deferred tax assets and liabilities based on differences between the financial statement bases and tax bases of our assets and liabilities . deferred tax assets and liabilities are recorded based upon enacted tax rates for the period in which the deferred tax items are expected to reverse . changes in tax laws or tax rates in various jurisdictions are reflected in the period of change . significant judgment is required in the calculation of our tax provision and the resulting tax liabilities as well as our ability to realize our deferred tax assets . our estimates of future taxable income and any changes to such estimates can significantly impact our tax provision in a given period . significant judgment is required in determining our ability to realize our deferred tax assets related to federal , state and foreign tax attributes within their carryforward periods including estimating the amount and timing of the future reversal of deferred tax items in our projections of future taxable income . a valuation allowance is established to reduce deferred tax assets to the amounts we expect to realize in the future . we also recognize tax benefits related to uncertain tax positions only when we estimate that it is “ more likely than not ” that the position will be sustainable based on its technical merits . if actual results are not consistent with our estimates and assumptions , this may result in material changes to our income tax provision . long-lived assets we assess the recoverability of long-lived assets when indicators of impairment exist . we assess the possibility of impairment by comparing the carrying amounts of the assets to the estimated undiscounted future cash flows expected to be generated by those assets
