⁽¹⁾Reclassification results from enhancements to the ALLL calculation during the second quarter of 2013 that resulted in the allocation of $15.8 million previously designated as 'nonspecific' to other loan classes and the absorption of $7.4 million of the reserve for unfunded commitments related to unfunded, revocable loan commitments into the ALLL. Further discussion is contained in Note A.

The commercial mortgage loan class had a net credit provision of $16.7 million for the year ended December 31, 2014 compared to a net credit provision of $4.5 million for the year ended December 31, 2013. The increase in the net credit provision was primarily the result of continued improvements in the credit risk rating mix and lower credit default trends within this loan class.

The provision expense for commercial and industrial loans totaled $10.4 million for the year ended December 31, 2014 compared to $4.3 million for the year ended December 31, 2013. Loan growth of $907.8 million during the year was the primary result of the increase in provision expense.

The provision for lease financing was a net credit of $0.5 million for the year ended December 31, 2014 compared to a provision expense of $1.6 million for the year ended December 31, 2013. The decrease was primarily the result of continued improvements in the credit risk rating mix and lower credit default trends within this loan class.

The other loan class had a provision expense of $3.0 million for the year ended December 31, 2014 compared to a provision expense of $0.3 million for the year ended December 31, 2013. The increase in the provision expense was attributable to newly originated loans as well as declining trends in credit risk ratings and defaults.

In the non-PCI commercial mortgage segment, loans and leases individually evaluated for impairment decreased $14.3 million to $82.8 million as of December 31, 2014 due to credit quality improvement as certain loans were no longer considered impaired during 2014 and fewer loans were identified for impairment. Reserves on impaired commercial mortgage loans increased $1.7 million due to cash flow deterioration on various individual large relationships.

Other loans and leases individually evaluated for impairment increased $2.0 million as of December 31, 2014 primarily due to one lending relationship which was almost fully reserved due to the loan being placed on nonaccrual status and being unsecured.

Non-PCI loans and leases individually evaluated for impairment decreased $12.6 million to $119.6 million at December 31, 2014 in comparison to December 31, 2013 due to continued credit quality improvements, primarily in the commercial mortgage portfolio. In contrast, Non-PCI loans and leases collectively evaluated for impairment increased $5.49 billion from December 31, 2013 to December 31, 2014. This increase is driven by the addition of non-PCI loans acquired in the Bancorporation merger of $4.18 billion as of the acquisition date and originated loan growth.

Further discussion is contained in Note A.

The commercial mortgage loan class had a net credit provision of $16.7 million for the year ended December 31, 2014 compared to a net credit provision of $4.5 million for the year ended December 31, 2013. The increase in the net credit provision was primarily the result of continued improvements in the credit risk rating mix and lower credit default trends within this loan class.

The provision expense for commercial and industrial loans totaled $10.4 million for the year ended December 31, 2014 compared to $4.3 million for the year ended December 31, 2013. Loan growth of $907.8 million during the year was the primary result of the increase in provision expense.

The provision for lease financing was a net credit of $0.5 million for the year ended December 31, 2014 compared to a provision expense of $1.6 million for the year ended December 31, 2013. The decrease was primarily the result of continued improvements in the credit risk rating mix and lower credit default trends within this loan class.

The other loan class had a provision expense of $3.0 million for the year ended December 31, 2014 compared to a provision expense of $0.3 million for the year ended December 31, 2013. The increase in the provision expense was attributable to newly originated loans as well as declining trends in credit risk ratings and defaults.

In the non-PCI commercial mortgage segment, loans and leases individually evaluated for impairment decreased $14.3 million to $82.8 million as of December 31, 2014 due to credit quality improvement as certain loans were no longer considered impaired during 2014 and fewer loans were identified for impairment. Reserves on impaired commercial mortgage loans increased $1.7 million due to cash flow deterioration on various individual large relationships.

Other loans and leases individually evaluated for impairment increased $2.0 million as of December 31, 2014 primarily due to one lending relationship which was almost fully reserved due to the loan being placed on nonaccrual status and being unsecured.

Non-PCI loans and leases individually evaluated for impairment decreased $12.6 million to $119.6 million at December 31, 2014 in comparison to December 31, 2013 due to continued credit quality improvements, primarily in the commercial mortgage portfolio. In contrast, Non-PCI loans and leases collectively evaluated for impairment increased $5.49 billion from December 31, 2013 to December 31, 2014. This increase is driven by the addition of non-PCI loans acquired in the Bancorporation merger of $4.18 billion as of the acquisition date and originated loan growth.

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, Loans and Debt Securities Acquired with Deteriorated Credit Quality, 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, 2014, equaled $151.5 million, of which $46.9 million were PCI and $104.6 million were non-PCI. TDRs at December 31, 2013, totaled $206.8 million, which consisted of $102.3 million PCI and $104.4 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 determining 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.

.

The following tables provide the types of TDRs made during the twelve months ended December 31, 2014, and 2013, as well as a summary of loans that were modified as a TDR during the 12 months ended December 31, 2014, and 2013 that subsequently defaulted during the

twelve months ended December 31, 2014, and 2013. 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 Restructuring, Summary of Accrual Status [Table Text Block]
