﻿ The following briefly describes the composition of each loan category. ﻿ Commercial and industrial ﻿ Commercial and industrial loans are made available to businesses for working capital (including financing of inventory and receivables), business expansion, to facilitate the acquisition of a business, and the purchase of equipment and machinery, including equipment leasing. These loans are primarily made based on the identified cash flows of the borrower and, when secured, have the added strength of the underlying collateral. ﻿ Commercial non-real estate loans may be secured by the assets being financed or other tangible or intangible business assets such as accounts receivable, inventory, ownership, enterprise value or commodity interests, and may incorporate a personal or corporate guarantee; however, some short-term loans may be made on an unsecured basis, including a small portfolio of corporate credit cards, generally issued as a part of overall customer relationships. ﻿ Commercial real estate – owner occupied loans consist of commercial mortgages on properties where repayment is generally dependent on the cash flow from the ongoing operations and activities of the borrower. Like commercial non-real estate, these loans are primarily made based on the identified cash flows of the borrower, but also have the added strength of the value of underlying real estate collateral. ﻿ Commercial real estate – income producing ﻿ Commercial real estate – income producing loans consist of loans secured by commercial mortgages on properties where the loan is made to real estate developers or investors and repayment is dependent on the sale, refinance, or income generated from the operation of the property. Properties financed include retail, office, multifamily, senior housing, hotel/motel, skilled nursing facilities and other commercial properties. ﻿ Construction and land development ﻿ C onstruction and land development loans are made to facilitate t he acquisition, development, improvement and construction of both commercial and residential-purpose properties. Such loans are made to builders and investors where repayment is expected to be made from the sale, refinance or operation of the property or to businesses to be used in their business operations. This portfolio also includes a small amount of residential construction loans and loans secured by raw land not yet under development. ﻿ Residential m ortgages ﻿ Residential mortgages consist of closed-end loans secured by first liens on 1- 4 family residential properties. The portfolio includes both fixed and adjustable rate loans, although most longer term, fixed rate loans originated are sold in the secondary mortgage market. ﻿ Consumer ﻿ Consumer loans include second lien mortgage home loans, home equity lines of credit and nonresidential consumer purpose loans. Nonresidential consumer loans include both direct and indirect loans. Direct nonresidential consumer loans are made to finance the purchase of personal property, including automobiles, recreational vehicles and boats, and for other personal purposes (secured and unsecured), and deposit account secured loans. Indirect nonresidential consumer loans include automobile financing provided to the consumer through an agreement with automobile dealerships. Consumer loans also include a small portfolio of credit card receivables issued on the basis of applications received through referrals from the Bank’s branches, online and other marketing efforts. Allowance for Loan Losses The following tables show activity in the allowance for loan losses by portfolio class for the three months ended March 31, 2018 and 2017, as well as the corresponding recorded investment in loans at the end of each period. Charge-off, recovery and provision activity in the purchased credit impaired portfolio previously segregated has been collapsed into the remainder of the portfolio’s activity as it is no longer material, and the respective reclassifications have been made to the prior period to conform to the current presentation. ﻿ ﻿

Below are the definitions of the Company’s internally assigned grades: Commercial:
| · |  | Pass – loans properly approved, documented, collateralized, and performing which do not reflect an abnormal credit risk.
| · |  | Pass-Watch – credits in this category are of sufficient risk to cause concern. This category is reserved for credits that display negative performance trends. The “Watch” grade should be regarded as a transition category.
| · |  | Special Mention – a criticized asset category defined as having potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may, at some future date, result in the deterioration of the repayment prospects for the credit or the institution’s credit position. Special mention credits are not considered part of the Classified credit categories and do not expose the institution to sufficient risk to warrant adverse classification.
| · |  | Substandard – an asset that is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. 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 institution will sustain some loss if the deficiencies are not corrected.
| · |  | Doubtful – an asset that has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
| · |  | Loss – credits classified as Loss are considered uncollectable and are charged off promptly once so classified.
Residential and Consumer:
| · |  | Performing – loans on which payments of principal and interest are less than 90 days past due.
| · |  | Nonperforming – a nonperforming loan is a loan that is in default or close to being in default and there are good reasons to doubt that payments will be made in full. All loans rated as nonaccrual loans are also classified as nonperforming.

﻿ During the three months ended March 31, 2017, certain of the Company’s purchased credit impaired loans were covered by two loss share agreements with the FDIC. The Company had a receivable representing an indemnification asset arising from the agreements. The receivable was accounted for separately from the covered loans as the agreements were not contractually part of the loans and were not transferrable should the Company have disposed of the loans. The agreements were terminated by the Company during the third quarter of 2017. ﻿ ﻿ Residential Mortgage Loans in Process of Foreclosure ﻿ Included in loans are $7.8 million and $7.5 million of consumer loans secured by single family residential real estate that are in process of foreclosure as of March 31, 2018 and December 31, 2017, respectively. Loans in process of foreclosure include those for which formal foreclosure proceedings are in process according to local requirements of the applicable jurisdiction. In addition to the single family residential real estate loans in process of foreclosure, the Company also held $3.7 million and $3.4 million of foreclosed single family residential properties in other real estate owned as of March 31, 2018 and December 31, 2017, respectively.
