Allowance for Loan Losses An analysis of the allowance for loan losses is summarized as follows: Three Months Ended March 31, 2018 2017 (Dollars in thousands) Balance at beginning of the period $ 230,969 228,373 Loans charged off (7,107 ) (3,005 ) Recoveries 4,782 1,544 Net charge-offs (2,325 ) (1,461 ) Provision for loan losses 2,500 4,000 Balance at end of the period $ 231,144 230,912 The allowance for loan losses is the estimated amount considered necessary to cover credit losses inherent in the loan portfolio at the balance sheet date. The allowance is established through the provision for loan losses that is charged against income. In determining the allowance for loan losses, we make significant estimates and therefore, have identified the allowance as a critical accounting policy. The methodology for determining the allowance for loan losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the economic environment that could result in changes to the amount of the recorded allowance for loan losses. The allowance for loan losses has been determined in accordance with U.S. GAAP, under which we are required to maintain an allowance for probable losses at the balance sheet date. We are responsible for the timely and periodic determination of the amount of the allowance required. We believe that our allowance for loan losses is adequate to cover specifically identifiable losses, as well as estimated losses inherent in our portfolio for which certain losses are probable but not specifically identifiable. Loans acquired are marked to fair value on the date of acquisition with no valuation allowance reflected in the allowance for loan losses. In conjunction with the quarterly evaluation of the adequacy of the allowance for loan losses, the Company performs an analysis on acquired loans to determine whether or not an allowance should be ascribed to those loans. Purchased Credit-Impaired (“PCI”) loans, are loans acquired at a discount that is due, in part, to credit quality. PCI loans are accounted for in accordance with ASC Subtopic 310-30 and are initially recorded at fair value as determined by the present value of expected future cash flows with no valuation allowance reflected in the allowance for loan losses. For the three months ended March 31, 2018 and 2017 , the Company recorded charge-offs of $88,000 and $33,000 , respectively, related to PCI loans acquired. Management performs a quarterly evaluation of the adequacy of the allowance for loan losses. The analysis of the allowance for loan losses has two components: specific and general allocations. Specific allocations are made for loans determined to be impaired. A loan is deemed to be impaired if it is a commercial loan with an outstanding balance greater than $1.0 million and on non-accrual status, loans modified in a troubled debt restructuring (“TDR”), and other commercial loans greater than $1.0 million if management has specific information that it is probable they will not collect all amounts due under the contractual terms of the loan agreement. Impairment is measured by determining the present value of expected future cash flows or, for collateral-dependent loans, the fair value of the collateral adjusted for market conditions and selling expenses. The general allocation is determined by segregating the remaining loans by type of loan, risk rating (if applicable) and payment history. In addition, the Company’s residential portfolio is subdivided between fixed and adjustable rate loans as adjustable rate loans are deemed to be subject to more credit risk if interest rates rise. Reserves for each loan segment or the loss factors are generally determined based on the Company’s historical loss experience over a look-back period determined to provide the appropriate amount of data to accurately estimate expected losses as of period end. Additionally, management assesses the loss emergence period for the expected losses of each loan segment and adjusts each historical loss factor accordingly. The loss emergence period is the estimated time from the date of a loss event (such as a personal bankruptcy) to the actual recognition of the loss (typically via the first full or partial loan charge-off), and is determined based upon a study of the Company’s past loss experience by loan segment. The loss factors may also be adjusted to account for qualitative or environmental factors that are likely to cause estimated credit losses inherent in the portfolio to differ from historical loss experience. This evaluation is based on among other things, loan and delinquency trends, general economic conditions, credit concentrations, industry trends and lending and credit management policies and procedures, but is inherently subjective as it requires material estimates that may be susceptible to significant revisions based upon changes in economic and real estate market conditions. Actual loan losses may be different than the allowance for loan losses we have established which could have a material negative effect on our financial results. On a quarterly basis, management reviews the current status of various loan assets in order to evaluate the adequacy of the allowance for loan losses. In this evaluation process, specific loans are analyzed to determine their potential risk of loss. Loans determined to be impaired are evaluated for potential loss exposure. Any shortfall results in a recommendation of a specific allowance or charge-off if the likelihood of loss is evaluated as probable. To determine the adequacy of collateral on a particular loan, an estimate of the fair value of the collateral is based on the most current appraised value available for real property or a discounted cash flow analysis on a business. The appraised value for real property is then reduced to reflect estimated liquidation expenses. The allowance contains reserves identified as unallocated. These reserves reflect management’s attempt to provide for the imprecision and the uncertainty that is inherent in estimates of probable credit losses. Our lending emphasis has been the origination of multi-family loans, commercial real estate loans, commercial and industrial loans, one- to four-family residential mortgage loans secured by one- to four-family residential real estate, construction loans and consumer loans, the majority of which are home equity loans, home equity lines of credit and cash surrender value lending on life insurance contracts. These activities resulted in a concentration of loans secured by real estate property and businesses located in New Jersey and New York. Based on the composition of our loan portfolio, we believe the primary risks to our loan portfolio are increases in interest rates, a decline in the general economy, and declines in real estate market values in New Jersey, New York and surrounding states. Any one or combination of these events may adversely affect our loan portfolio resulting in increased delinquencies, loan losses and future levels of loan loss provisions. As a substantial amount of our loan portfolio is collateralized by real estate, appraisals of the underlying value of property securing loans are critical in determining the amount of the allowance required for specific loans. Assumptions for appraisal valuations are instrumental in determining the value of properties. Negative changes to appraisal assumptions could significantly impact the valuation of a property securing a loan and the related allowance determined. The assumptions supporting such appraisals are carefully reviewed to determine that the resulting values reasonably reflect amounts realizable on the related loans. The Company obtains an appraisal for all commercial loans that are collateral dependent upon origination. An updated appraisal is obtained annually for loans rated substandard or worse with a balance of $500,000 or greater. An updated appraisal is obtained biennially for loans rated special mention with a balance of $2.0 million or greater. This is done in order to determine the specific reserve or charge off needed. As part of the allowance for loan losses process, the Company reviews each collateral dependent commercial loan classified as non-accrual and/or impaired and assesses whether there has been an adverse change in the collateral value supporting the loan. The Company utilizes information from its commercial lending officers and its credit department and special assets department’s knowledge of changes in real estate conditions in our lending area to identify if possible deterioration of collateral value has occurred. Based on the severity of the changes in market conditions, management determines if an updated appraisal is warranted or if downward adjustments to the previous appraisal are warranted. If it is determined that the deterioration of the collateral value is significant enough to warrant ordering a new appraisal, an estimate of the downward adjustments to the existing appraised value is used in assessing if additional specific reserves are necessary until the updated appraisal is received. For homogeneous residential mortgage loans, the Company’s policy is to obtain an appraisal upon the origination of the loan and an updated appraisal in the event a loan becomes 90 days delinquent. Thereafter, the appraisal is updated every two years if the loan remains in non-performing status and the foreclosure process has not been completed. Management adjusts the appraised value of residential loans to reflect estimated selling costs and declines in the real estate market. Management believes the potential risk for outdated appraisals for impaired and other non-performing loans has been mitigated due to the fact that the loans are individually assessed to determine that the loan’s carrying value is not in excess of the fair value of the collateral. Loans are generally charged off after an analysis is completed which indicates that collectability of the full principal balance is in doubt. Although we believe we have established and maintained the allowance for loan losses at adequate levels, additions may be necessary if the current economic environment deteriorates. Management uses relevant information available; however, the level of the allowance for loan losses remains an estimate that is subject to significant judgment and short-term change. In addition, the Federal Deposit Insurance Corporation and the New Jersey Department of Banking and Insurance, as an integral part of their examination process, will periodically review our allowance for loan losses. Such agencies may require us to recognize adjustments to the allowance based on their judgments about information available to them at the time of their examination.

For non-homogeneous loans, such as commercial and commercial real estate loans, the Company analyzes the loans individually by classifying the loans as to credit risk and assesses the probability of collection for each type of class. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: Pass - “Pass” assets are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral in a timely manner. Watch - A “Watch” asset has all the characteristics of a Pass asset but warrants more than the normal level of supervision. These loans may require more detailed reporting to management because some aspects of underwriting may not conform to policy or adverse events may have affected or could affect the cash flow or ability to continue operating profitably, provided, however, the events do not constitute an undue credit risk. Residential and consumer loans delinquent 30 - 59 days are considered watch if not already identified as impaired. Special Mention - A “Special Mention” asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Residential and consumer loans delinquent 60 - 89 days are considered special mention if not already identified as impaired. Substandard - A “Substandard” asset is inadequately protected by the current worth and paying capacity of the obligor or by 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. Residential and consumer loans delinquent 90 days or greater as well as those identified as impaired are considered substandard. Doubtful - An asset classified “Doubtful” has all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values. Loss - An asset or portion thereof, classified “Loss” is considered uncollectible and of such little value that its continuance on the institution’s books as an asset, without establishment of a specific valuation allowance or charge-off, is not warranted. This classification does not necessarily mean that an asset has no recovery or salvage value; but rather, there is much doubt about whether, how much, or when the recovery will occur. As such, it is not practical or desirable to defer the write-off.

Troubled Debt Restructurings On a case-by-case basis, the Company may agree to modify the contractual terms of a borrower’s loan to remain competitive and assist customers who may be experiencing financial difficulty, as well as preserve the Company’s position in the loan. If the borrower is experiencing financial difficulties and a concession has been made at the time of such modification, the loan is classified as a TDR. Substantially all of our TDR loan modifications involve lowering the monthly payments on such loans through either a reduction in interest rate below a market rate, an extension of the term of the loan, or a combination of these two methods. These modifications rarely result in the forgiveness of principal or accrued interest. In addition, we frequently obtain additional collateral or guarantor support when modifying commercial loans. Restructured loans remain on non-accrual status until there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The following tables present the total TDR loans at March 31, 2018 and December 31, 2017 . There were five residential PCI loans that were classified as TDRs for the period ended March 31, 2018 . There were four residential PCI loans that were classified as TDRs for the period ended December 31, 2017 .

All TDRs are impaired loans, which are individually evaluated for impairment, as discussed above. Collateral dependent impaired loans classified as TDRs were written down to the estimated fair value of the collateral. There were charge-offs of $172,000 and $100,000 for collateral dependent TDRs during the three months ended March 31, 2018 and March 31, 2017 , respectively. The allowance for loan losses associated with the TDRs presented in the above tables totaled $1.7 million and $1.8 million at March 31, 2018 and December 31, 2017 , respectively. Residential mortgage loan modifications generally involve the reduction in loan interest rate and extension of loan maturity dates and also may include step up interest rates in their modified terms which will impact their weighted average yield in the future. All residential loans deemed to be TDRs were modified to reflect a reduction in interest rates to current market rates. The commercial loan modifications which qualified as TDRs had their maturity extended as well as the reduction in loan interest rate.
