Non-Traditional Mortgage Loans The Company’s NTM portfolio is comprised of three interest only products: Green Loans, Interest Only loans and a small number of additional loans with the potential for negative amortization. As of December 31, 2017 and 2016, the NTM loans totaled $806.9 million, or 12.1 percent of total loans and leases, and $885.1 million, or 14.7 percent of total loans and leases, respectively. The total NTM portfolio decreased by $78.2 million, or 8.8 percent, during the year ended December 31, 2017.

Green Loans Green Loans are single family residential first and second mortgage lines of credit with a linked checking account that allows all types of deposits and withdrawals to be performed. The loans are generally interest only for a 15-year term with a balloon payment due at maturity. At December 31, 2017 and 2016, Green Loans totaled $85.8 million and $91.0 million, respectively. At December 31, 2017 and 2016, none of the Company’s Green Loans were non-performing. As a result of their unique payment feature, Green Loans possess higher credit risk due to the potential for negative amortization; however, management believes the risk is mitigated through the Company’s loan terms and underwriting standards, including its policies on LTV ratios and the Company’s contractual ability to curtail loans when the value of the underlying collateral declines. The Company discontinued origination of the Green Loan products in 2011. Interest Only Loans Interest Only loans are primarily single family residential first mortgage loans with payment features that allow interest only payments in initial periods before converting to a fully amortizing loan. At December 31, 2017 and 2016, Interest Only loans totaled $717.5 million and $784.4 million, respectively. At December 31, 2017 and 2016, $1.2 million and $467 thousand of the Interest Only loans were non-performing, respectively. Loans with the Potential for Negative Amortization Negative amortization loans totaled $3.7 million and $9.8 million at December 31, 2017 and 2016, respectively. The Company discontinued origination of negative amortization loans in 2007. At December 31, 2017 and 2016, none of the loans with the potential for negative amortization were non-performing. These loans pose a potentially higher credit risk because of the lack of principal amortization and potential for negative amortization; however, management believes the risk is mitigated through the loan terms and underwriting standards, including the Company’s policies on LTV ratios. Risk Management of Non-Traditional Mortgages The Company has determined that significant performance indicators for NTMs are LTV ratios and FICO scores. Accordingly, the Company manages credit risk in the NTM portfolio through periodic review of the loan portfolio that includes refreshing FICO scores on the Green Loans and HELOCs, as needed in conjunction with portfolio management, and ordering third party AVMs. The loan review is designed to provide a method of identifying borrowers who may be experiencing financial difficulty before they actually fail to make a loan payment. Upon receipt of the updated FICO scores, an exception report is run to identify loans with a decrease in FICO score of 10 percent or more and/or a resulting FICO score of 620 or less. The loans are then further analyzed to determine if the risk rating should be downgraded, which will increase the reserves the Company will establish for potential losses. A report of the periodic loan review is published and regularly monitored. As these loans are revolving lines of credit, the Company, based on the loan agreement and loan covenants of the particular loan, as well as applicable rules and regulations, could suspend the borrowing privileges or reduce the credit limit at any time the Company reasonably believes that the borrower will be unable to fulfill their repayment obligations under the agreement or certain other conditions are met. In many cases, the decrease in FICO score is the first indication that the borrower may have difficulty in making their future payment obligations. The Company proactively manages the NTM portfolio by performing detailed analyses on the portfolio. The Company’s IARC meets at least quarterly to review the loans classified as special mention, substandard, or doubtful and determines whether a suspension or reduction in credit limit is warranted. If a line has been suspended and the borrower would like to have their credit privileges reinstated, they would need to provide updated financials showing their ability to meet their payment obligations. On the interest only loans, the Company projects future payment changes to determine if there will be a material increase in the required payment and then monitors the loans for possible delinquency. Individual loans are monitored for possible downgrading of risk rating.

Allowance for Loan and Lease Losses The Company has established credit risk management processes that include regular management review of the loan and lease portfolio to identify problem loans and leases. During the ordinary course of business, management becomes aware of borrowers and lessees who may not be able to fulfill the contractual payment requirements of the loan and lease agreements. Such loans and leases are subject to increased monitoring. Consideration is given to placing the loan or lease on non-accrual status, assessing the need for additional ALLL, and partial or full charge-off of the principal balance. The Company maintains the ALLL at a level that is considered adequate to cover the estimated inherent risks in the loan and lease portfolio. The Company also maintains a separate reserve for unfunded loan commitments at a level that is considered adequate to cover the estimated inherent risks. The estimated funding of the loan commitments and credit risk factors determined based on outstanding loans that share similar credit risk exposure are used to determine the adequacy of the reserve. At December 31, 2017 and 2016, the reserve for unfunded loan commitments was $3.7 million and $2.4 million, respectively. The credit risk monitoring system is designed to identify impaired and potential problem loans, and to perform periodic evaluation of impairment and the adequacy of the allowance for credit losses in a timely manner. In addition, the Board of Directors of the Bank has adopted a credit policy that includes a credit review and control system that it believes should be effective in ensuring that the Company maintains an adequate allowance for loan and lease losses. The Board of Directors also provides oversight and guidance for management’s allowance evaluation process. During the three months ended March 31, 2017, the Company, as part of its continuous evaluation of the ALLL methodology and assumptions, determined that it was appropriate to change from a rolling 28-quarter look-back period to a cumulative look-back period with a pegged (fixed) starting point (the quarter ended March 31, 2008). The Company believes that an extended period of observed credit loss stability warranted the review of a longer historical period that captured a full credit cycle. Accordingly, as of December 31, 2017, the Company's look-back period was extended to 39-quarters. The Company further enhanced the methodology in the areas of qualitative adjustments and loan segmentation during the second quarter of 2017, and performed an annual update of the loss emergence period during the third quarter of 2017. These updates were designed to be systematic, transparent, and repeatable. The annual update of the loss emergence period resulted in an increase of $1.9 million in the ALLL at September 30, 2017. The updates on qualitative adjustments and loan segmentation did not have a material impact. The following table presents a summary of activity in the ALLL for the periods indicated:

At December 31, 2017 and 2016, none of loans were past due 90 days or more and still accruing. Loans in Process of Foreclosure At December 31, 2017 and 2016, the Company's SFR mortgage loans of $4.3 million and $2.2 million, respectively, were in the process of foreclosure. Troubled Debt Restructurings A modification of a loan constitutes a TDR when the Company, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. The concessions may be granted in various forms, including reduction in the stated interest rate, reduction in the amount of principal amortization, forgiveness of a portion of the loan balance or accrued interest, or extension of the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. Troubled debt restructured loans and leases consist of the following as of the dates indicated:

Credit Quality Indicators The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company performs historical loss analysis that is combined with a comprehensive loan or lease to value analysis to analyze the associated risks in the current loan and lease portfolio. The Company analyzes loans and leases individually by classifying the loans and leases as to credit risk. This analysis includes all loans and leases delinquent over 60 days and non-homogeneous loans and leases such as commercial and commercial real estate loans and leases. The Company uses the following definitions for risk ratings: Pass: Loans and leases classified as pass are in compliance in all respects with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weakness as defined under “Special Mention”, “Substandard” or “Doubtful”. Special Mention: Loans and leases classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease or of the Company’s credit position at some future date. Substandard: Loans and leases classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans and leases so classified 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: Loans and leases classified as doubtful have all the weaknesses inherent in those classified as 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. Not-Rated: When accrual of income on a pool of PCI loans with common risk characteristics is appropriate in accordance with ASC 310-30, individual loans in those pools are not risk-rated. The credit criteria evaluated are FICO scores, LTV ratios, delinquency, and actual cash flows versus expected cash flows of the loan pools. Loans and leases not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans and leases.
