note 10 loan sales and securitizations loan sales we sell residential and commercial mortgage loans in loan securitization transactions sponsored by government national mortgage association ( gnma ) , fnma , and fhlmc and in certain instances to other third-party investors .
gnma , fnma , and the fhlmc securitize our transferred loans into mortgage-backed securities for sale into the secondary market .
generally , we do not retain any interest in the transferred loans other than mortgage servicing rights .
refer to note 9 goodwill and other intangible assets for further discussion on our residential and commercial mortgage servicing rights assets .
during 2009 , residential and commercial mortgage loans sold totaled $ 19.8 billion and $ 5.7 billion , respectively .
during 2008 , commercial mortgage loans sold totaled $ 3.1 billion .
there were no residential mortgage loans sales in 2008 as these activities were obtained through our acquisition of national city .
our continuing involvement in these loan sales consists primarily of servicing and limited repurchase obligations for loan and servicer breaches in representations and warranties .
generally , we hold a cleanup call repurchase option for loans sold with servicing retained to the other third-party investors .
in certain circumstances as servicer , we advance principal and interest payments to the gses and other third-party investors and also may make collateral protection advances .
our risk of loss in these servicing advances has historically been minimal .
we maintain a liability for estimated losses on loans expected to be repurchased as a result of breaches in loan and servicer representations and warranties .
we have also entered into recourse arrangements associated with commercial mortgage loans sold to fnma and fhlmc .
refer to note 25 commitments and guarantees for further discussion on our repurchase liability and recourse arrangements .
our maximum exposure to loss in our loan sale activities is limited to these repurchase and recourse obligations .
in addition , for certain loans transferred in the gnma and fnma transactions , we hold an option to repurchase individual delinquent loans that meet certain criteria .
without prior authorization from these gses , this option gives pnc the ability to repurchase the delinquent loan at par .
under gaap , once we have the unilateral ability to repurchase the delinquent loan , effective control over the loan has been regained and we are required to recognize the loan and a corresponding repurchase liability on the balance sheet regardless of our intent to repurchase the loan .
at december 31 , 2009 and december 31 , 2008 , the balance of our repurchase option asset and liability totaled $ 577 million and $ 476 million , respectively .
securitizations in securitizations , loans are typically transferred to a qualifying special purpose entity ( qspe ) that is demonstrably distinct from the transferor to transfer the risk from our consolidated balance sheet .
a qspe is a bankruptcy-remote trust allowed to perform only certain passive activities .
in addition , these entities are self-liquidating and in certain instances are structured as real estate mortgage investment conduits ( remics ) for tax purposes .
the qspes are generally financed by issuing certificates for various levels of senior and subordinated tranches .
qspes are exempt from consolidation provided certain conditions are met .
our securitization activities were primarily obtained through our acquisition of national city .
credit card receivables , automobile , and residential mortgage loans were securitized through qspes sponsored by ncb .
these qspes were financed primarily through the issuance and sale of beneficial interests to independent third parties and were not consolidated on our balance sheet at december 31 , 2009 or december 31 , 2008 .
however , see note 1 accounting policies regarding accounting guidance that impacts the accounting for these qspes effective january 1 , 2010 .
qualitative and quantitative information about the securitization qspes and our retained interests in these transactions follow .
the following summarizes the assets and liabilities of the securitization qspes associated with securitization transactions that were outstanding at december 31 , 2009. .

credit card loans at december 31 , 2009 , the credit card securitization series 2005-1 , 2006-1 , 2007-1 , and 2008-3 were outstanding .
during the fourth quarter of 2009 , the 2008-1 and 2008-2 credit card securitization series matured .
our continuing involvement in the securitized credit card receivables consists primarily of servicing and our holding of certain retained interests .
servicing fees earned approximate current market rates for servicing fees ; therefore , no servicing asset or liability is recognized .
we hold a clean-up call repurchase option to the extent a securitization series extends past its scheduled note principal payoff date .
to the extent this occurs , the clean-up call option is triggered when the principal balance of the asset- backed notes of any series reaches 5% ( 5 % ) of the initial principal balance of the asset-backed notes issued at the securitization .
