In evaluating the loan portfolio for an appropriate ALL level, non-impaired loans that were not accounted for under ASC 310-30 were grouped into segments based on broad characteristics such as primary use and underlying collateral. Within the segments, the portfolio was further disaggregated into classes of loans with similar attributes and risk characteristics for purposes of applying loss ratios and determining applicable subjective adjustments to the ALL. The application of subjective adjustments was based upon qualitative risk factors, including economic trends and conditions, industry conditions, asset quality, loss trends, lending management, portfolio growth and loan review/internal audit results.

The Company had $0.1 million net charge-offs on non 310-30 loans during the three months ended March 31, 2017. Management's evaluation of credit quality resulted in a provision for loan losses on the non 310-30 loans of $1.8 million during the three months ended March 31, 2017, driven by loan growth and increased reserves of $0.5 million for one energy credit previously placed on non-accrual. During the three months ended March 31, 2016, the Company had $0.6 million of net charge offs on non ASC 310-30 loans and recorded a provision for loan losses on non 310-30 loans of $11.5 million, driven by increased reserves against the energy sector portfolio of $10.7 million, including increased specific reserves of $9.1 million on four impaired loans.

During the three months ended March 31, 2017 and 2016, the Company re-estimated the expected cash flows of the loan pools accounted for under ASC 310-30. The re-measurement during the three months ended March 31, 2017 resulted in a net recoupment of $5 thousand. The re-measurement during the three months ended March 31, 2016 resulted in a net recoupment of $862 thousand for the three months ended March 31, 2016, which was comprised primarily of a recoupment of $714 thousand in the commercial segment and a recoupment of $169 thousand in the non-owner occupied commercial real estate segment.
