Please answer the given financial question based on the context.
Context: troubled debt restructurings ( tdrs ) a tdr is a loan whose terms have been restructured in a manner that grants a concession to a borrower experiencing financial difficulties . tdrs typically result from our loss mitigation activities and include rate reductions , principal forgiveness , postponement/reduction of scheduled amortization , extensions , and bankruptcy discharges where no formal reaffirmation was provided by the borrower and therefore a concession has been granted based upon discharge from personal liability , which are intended to minimize economic loss and to avoid foreclosure or repossession of collateral . in those situations where principal is forgiven , the amount of such principal forgiveness is immediately charged some tdrs may not ultimately result in the full collection of principal and interest , as restructured , and result in potential incremental losses . these potential incremental losses have been factored into our overall alll estimate . the level of any subsequent defaults will likely be affected by future economic conditions . once a loan becomes a tdr , it will continue to be reported as a tdr until it is ultimately repaid in full , the collateral is foreclosed upon , or it is fully charged off . we held specific reserves in the alll of $ 587 million and $ 580 million at december 31 , 2012 and december 31 , 2011 , respectively , for the total tdr portfolio . table 71 : summary of troubled debt restructurings in millions dec . 31 dec . 31 .

( a ) pursuant to regulatory guidance issued in the third quarter of 2012 , additional troubled debt restructurings related to changes in treatment of certain loans of $ 366 million in 2012 , net of charge-offs , resulting from bankruptcy where no formal reaffirmation was provided by the borrower and therefore a concession has been granted based upon discharge from personal liability were added to the consumer lending population . the additional tdr population increased nonperforming loans by $ 288 million . charge-offs have been taken where the fair value less costs to sell the collateral was less than the recorded investment of the loan and were $ 128.1 million . of these nonperforming loans , approximately 78% ( 78 % ) were current on their payments at december 31 , 2012 . ( b ) accruing loans have demonstrated a period of at least six months of performance under the restructured terms and are excluded from nonperforming loans . ( c ) includes credit cards and certain small business and consumer credit agreements whose terms have been restructured and are tdrs . however , since our policy is to exempt these loans from being placed on nonaccrual status as permitted by regulatory guidance as generally these loans are directly charged off in the period that they become 180 days past due , these loans are excluded from nonperforming loans . the following table quantifies the number of loans that were classified as tdrs as well as the change in the recorded investments as a result of the tdr classification during the years ended december 31 , 2012 and 2011 . additionally , the table provides information about the types of tdr concessions . the principal forgiveness tdr category includes principal forgiveness and accrued interest forgiveness . these types of tdrs result in a write down of the recorded investment and a charge-off if such action has not already taken place . the rate reduction tdr category includes reduced interest rate and interest deferral . the tdrs within this category would result in reductions to future interest income . the other tdr category primarily includes postponement/reduction of scheduled amortization , as well as contractual extensions . in some cases , there have been multiple concessions granted on one loan . when there have been multiple concessions granted , the principal forgiveness tdr was prioritized for purposes of determining the inclusion in the table below . for example , if there is principal forgiveness in conjunction with lower interest rate and postponement of amortization , the type of concession will be reported as principal forgiveness . second in priority would be rate reduction . for example , if there is an interest rate reduction in conjunction with postponement of amortization , the type of concession will be reported as a rate reduction . the pnc financial services group , inc . 2013 form 10-k 155 .
