Troubled Debt Restructurings BancShares accounts for certain loan modifications or restructurings as TDRs. In general, the modification or restructuring of a loan is considered a TDR if, for economic reasons or legal reasons related to a borrower's financial difficulties, a concession is granted to the borrower that creditors would not otherwise consider. Concessions may relate to the contractual interest rate, maturity date, payment structure or other actions. In accordance with GAAP, loans acquired under ASC 310-30, excluding pooled loans, are not initially considered to be TDRs, but can be classified as such if a modification is made subsequent to acquisition. Subsequent modification of a PCI loan accounted for in a pool that would otherwise meet the definition of a TDR is not reported, or accounted for, as a TDR since pooled PCI loans are excluded from the scope of TDR accounting. The following table provides a summary of total TDRs by accrual status.

Total troubled debt restructurings at December 31, 2015, were $144.8 million, of which $30.6 million were PCI and $114.2 million were non-PCI. TDRs at December 31, 2014, were $151.5 million, which consisted of $46.9 million PCI and $104.6 million non-PCI. The majority of TDRs are included in the special mention, substandard or doubtful grading categories, which results in more elevated loss expectations when projecting the expected cash flows that are used to determine the allowance for loan losses associated with these loans. When a restructured loan subsequently defaults, it is evaluated and downgraded if appropriate. The more severely graded the loan, the lower the estimated expected cash flows and the greater the allowance recorded. Further, TDRs over $500,000 and graded substandard or lower are evaluated individually for impairment through a review of collateral values or analysis of cash flows. The following tables provide the types of TDRs made during the year ended December 31, 2015, and 2014, as well as a summary of loans that were modified as a TDR during the year ended December 31, 2015, and 2014 that subsequently defaulted during the year ended December 31, 2015, and 2014. BancShares defines payment default as movement of the TDR to nonaccrual status, which is generally 90 days past due for TDRs, foreclosure or charge-off, whichever occurs first.

Troubled Debt Restructurings on Financing Receivables | The following tables provide the types of TDRs made during the year ended December 31, 2015, and 2014, as well as a summary of loans that were modified as a TDR during the year ended December 31, 2015, and 2014 that subsequently defaulted during the year ended December 31, 2015, and 2014. BancShares defines payment default as movement of the TDR to nonaccrual status, which is generally 90 days past due for TDRs, foreclosure or charge-off, whichever occurs first.
