As of September 30, 2017, our acquired loans from the 2015 Integrity Bancshares, Inc. merger, or the Merger, were $415 million which included $219 million of Commercial Real Estate, or CRE, $103 million of Commercial & Industrial, or C&I, $15 million of commercial construction, $60 million of residential mortgage and $18 million of home equity, installment and other consumer construction. As of December 31, 2016 acquired loans were $543 million which included $273 million of CRE, $141 million of C&I, $33.0 million of commercial construction, $74.0 million of residential mortgage and $22.0 million of home equity, installment and other consumer construction.

We attempt to limit our exposure to credit risk by diversifying our loan portfolio by segment, geography, collateral and industry and actively managing concentrations. When concentrations exist in certain segments, we monitor this risk by reviewing the relevant economic indicators and internal risk rating trends and through stress testing of the loans in these segments. Total commercial loans represented 78 percent of total portfolio loans at September 30, 2017 and December 31, 2016. Within our commercial portfolio, the CRE and commercial construction portfolios comprised $3.1 billion or 68 percent of total commercial loans and 54 percent of total portfolio loans at September 30, 2017 and comprised of $3.0 billion or 68 percent of total commercial loans and 53 percent of total portfolio loans at December 31, 2016. Further segmentation of the CRE and Commercial Construction portfolios by collateral type reveals no concentration in excess of 14 percent of total CRE and Commercial Construction loans at September 30, 2017 and December 31, 2016.

Our market area includes Pennsylvania and the contiguous states of Ohio, West Virginia, New York and Maryland. The majority of our commercial and consumer loans are made to businesses and individuals in this market area, resulting in a regional geographic concentration. We believe our knowledge and familiarity with customers and conditions locally outweighs this geographic concentration risk. The conditions of the local and regional economies are monitored closely through publicly available data as well as information supplied by our customers. Our CRE and Commercial Construction portfolios have out-of-market exposure of 5.1 percent of the total CRE and Commercial Construction portfolios and 2.7 percent of total loans at September 30, 2017. This compares to 5.2 percent of the total CRE and Commercial Construction portfolios and 2.7 percent of total loans at December 31, 2016.

The increase in loans held for sale of $44.1 million related to $43.4 million of loans that were held for sale due to a branch sale that is expected to close in the fourth quarter of 2017.

We individually evaluate all substandard commercial loans that have experienced a forbearance or change in terms agreement, as well as all substandard consumer and residential mortgage loans that entered into an agreement to modify their existing loan, to determine if they should be designated as troubled debt restructurings, or TDRs. All TDRs are considered to be impaired loans and will be reported as impaired loans for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. Further, all impaired loans are reported as nonaccrual loans unless the loan is a TDR that has met the requirements to be returned to accruing status. TDRs can be returned to accruing status if the ultimate collectability of all contractual amounts due, according to the restructured agreement, is not in doubt and there is a period of a minimum of six months of satisfactory payment performance by the borrower either immediately before or after the restructuring.

The following table summarizes restructured loans as of the dates presented:

For the three months ended September 30, 2017, we modified one CRE loan totaling $1.0 million that was not considered to be a TDR. For the nine months ended September 30, 2017, we modified 13 loans totaling $11.8 million of which nine were C&I loans totaling $10.3 million and four CRE loans totaling $1.5 million that were not considered to be TDRs. The 2017 modifications primarily represented insignificant delays in the timing of payments, concessions where we were adequately compensated through principal pay downs, fees or additional collateral or we concluded that no concession was granted. These modifications compare to 12 C&I loans totaling $16.9 million and one CRE loan totaling $1.9 million for the three months ended September 30, 2016 and 15 C&I loans totaling $25.6 million and two CRE loans totaling $2.5 million for the nine months ended September 30, 2016 that were not considered to be TDRs. The 2016 modifications were administrative extensions of maturity dates that were determined not to be a concession. As of September 30, 2017, we had no commitments to lend additional funds on TDRs.

Defaulted TDRs are defined as loans having a payment default of 90 days or more after the restructuring takes place. There were no TDRs that defaulted during the three and nine months ended September 30, 2017 and September 30, 2016.
