​ Net deferred loan origination costs included in the table above were $5.4 million as of June 30, 2019 and $5.6 million as of December 31, 2018. Net accretable purchase accounting adjustments included in the table above reduced loans by $25.0 million as of June 30, 2019 and $13.9 million as of December 31, 2018. ​ The Company utilizes a loan grading scale to assign a risk grade to all of its loans. A description of the general characteristics of each grade is as follows: ​
| ● | Pass- This category includes loans that are all considered strong credits, ranging from investment or near investment grade, to loans made to borrowers who exhibit credit fundamentals that exceed industry standards and loan policy guidelines and loans that exhibit acceptable credit fundamentals.
​
| ● | Watch- This category includes loans on management’s “Watch List” and is intended to be utilized on a temporary basis for a pass grade borrower where a significant risk-modifying action is anticipated in the near future.
​
| ● | Special mention- This category is for “Other Assets Specially Mentioned” loans that have potential weaknesses, which may, if not checked or corrected, weaken the asset or inadequately protect the Company’s credit position at some future date.
​
| ● | Substandard- This category includes “Substandard” loans, determined in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
​
| ● | Substandard Non-accrual- This category includes loans that have all the characteristics of a “Substandard” loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral with a value that is difficult to determine.
​ All loans are graded at their inception. Most commercial lending relationships that are $1.0 million or less are processed through an expedited underwriting process. If the credit receives a pass grade, it is aggregated into a homogenous pool of either: $0.35 million or less, or $0.35 million to $1.0 million. These pools are monitored on a regular basis and reviewed annually. Most commercial loans greater than $1.0 million are included in a portfolio review at least annually. Commercial loans greater than $0.35 million that have a grading of special mention or worse are reviewed on a quarterly basis. Interim reviews may take place if circumstances of the borrower warrant a more timely review. The following table is a summary of risk grades segregated by category of portfolio loans (excluding accretable purchase accounting adjustments and clearings) (dollars in thousands): ​

​ The gross interest income that would have been recorded in the three months ended June 30, 2019 and 2018 if impaired loans had been current in accordance with their original terms was $0.4 million and $0.3 million, respectively. The gross interest income that would have been recorded in the six months ended June 30, 2019 and 2018 if impaired loans had been current in accordance with their original terms was $1.1 million and $0.7 million, respectively. The amount of interest collected on those loans and recognized on a cash basis that was included in interest income was insignificant for the three and six months ended June 30, 2019 and 2018. A summary of troubled debt restructurings (“TDR”) loans is as follows (dollars in thousands): ​

Total | ​ | $ | 12,112 | ​ | $ | 8,838
​ Loans classified as a TDR during the three and six months ended June 30, 2019, included one commercial loan for payment modification with a recorded investment of $0.6 million. Loans classified as a TDR during the three and six months ended June 30, 2018 included one retail real estate modification for short-term interest rate relief, with a recorded investment of $0.1 million. ​ The gross interest income that would have been recorded in the three and six months ended June 30, 2019 and 2018 if TDRs had performed in accordance with their original terms compared with their modified terms was insignificant. ​ One commercial real estate TDR, with a recorded investment of $3.2 million, that was entered into during the last twelve months, was subsequently classified as non-performing and had payment defaults (a default occurs when a loan is 90 days or more past due or transferred to non-accrual) during the three and six months ended June 30, 2019. There were no TDRs that were entered into during the prior twelve months that were subsequently classified as non-performing and had payment defaults during the three and six months ended June 30, 2018. ​ At June 30, 2019, the Company had $2.6 million of residential real estate in the process of foreclosure. ​ The following tables provide details of loans identified as impaired, segregated by category. The unpaid contractual principal balance represents the recorded balance prior to any partial charge-offs. The recorded investment represents customer balances net of any partial charge-offs recognized on the loan. The average recorded investment is calculated using the most recent four quarters (dollars in thousands). ​

​ Management's evaluation as to the ultimate collectability of loans includes estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. These estimates are affected by changing economic conditions and the economic prospects of borrowers. ​ The Company holds acquired loans from business combinations with uncollected principal balances. These loans are carried net of a fair value adjustment for credit risk and interest rates and are only included in the allowance calculation to the extent that the reserve requirement exceeds the fair value adjustment. As the acquired loans renew, it is generally necessary to establish an allowance, which represents an amount that, in management’s opinion, will be adequate to absorb probable credit losses in such loans. The recorded investment of all acquired loans as of June 30, 2019 totaled approximately $1.8 billion. ​ The following table details activity in the allowance for loan losses. Allocation of a portion of the allowance to one category does not preclude its availability to absorb losses in other categories (dollars in thousands): ​
