Additionally, the Bank’s operations include a registered investment advisory business with assets held under management of $312 million at June 30, 2018. The Company is headquartered in Southfield, Michigan and its operations are in the financial services industry. Management evaluates the performance of its business based on one reportable segment, community banking. The Company is subject to regulation, examination and supervision by the Board of Governors of the Federal Reserve (“Federal Reserve”). The Bank is a federally chartered stock savings bank which is subject to regulation, supervision and examination by the Office of the Comptroller of the Currency (“OCC”) of the U.S. Department of Treasury and the Federal Deposit Insurance Corporation (“FDIC”) and is a member of the Federal Home Loan Bank (“FHLB”) system.

The Company received net proceeds of $85.5 million after deducting underwriting discounts and commissions of $5.5 million and other offering expenses of $1.3 million. The Company continues to use the proceeds to support the Bank’s growth initiatives. Basis of Presentation The condensed consolidated balance sheet as of June 30, 2018, and the condensed consolidated statements of income, comprehensive income, changes in shareholders’ equity and cash flows for the three and six months ended June 30, 2018 and 2017 are unaudited. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect, in the opinion of management, all normal and recurring adjustments, considered necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. The financial data and other financial information disclosed in these notes to the condensed consolidated financial statements related to these periods are also unaudited. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results that may be expected for the year ended December 31, 2018 or for any future annual or interim period. The consolidated balance sheet at December 31, 2017 included herein was derived from the audited financial statements as of that date. The accompanying unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Adjustments to Prior Interim Periods In the second quarter of 2018, the Company corrected the classification of commitment fees, net of direct loan origination costs, earned on construction loans and other lines of credit to commercial customers in its condensed consolidated statements of income to the financial statement caption, interest and fees on loans, within interest income, which were previously reported in service charges and fees, within non-interest income. The Company has made the correction to conform with accounting principles generally accepted in the United States of America ("U.S. GAAP"). As a result, prior period financial statements included herein have been adjusted from the amounts previously reported. The amount of the adjustment to decrease service charges and fees, and increase interest and fees on loans was $502 and $862 for the three and six months ended June 30, 2017, respectively. Additionally, the amount of this adjustment was $544 and $360 for the three months ended March 31, 2018 and 2017, respectively. There was no change to the reported net income or income per share, basic and diluted, as previously reported as a result of this immaterial correction. Management has evaluated the materiality of these corrections on its previously filed financial statements from a quantitative and qualitative perspective, and has concluded that these corrections were not material to the prior periods. Merger of Quantum Fund, LLC On April 24, 2017, the Bank acquired all the outstanding equity interests of Quantum Fund, LLC, an entity controlled by the Company’s principal shareholder who owned, directly and indirectly 80% of the members’ interests with the remaining 20% members’ interest held by a member of the Board of Directors of the Company and Bank, for $2.9 million in cash. The entity operated a registered investment advisory business with assets held under management of approximately $425 million. In 2017, the Bank recorded the assets and liabilities transferred at their carrying amounts, consisting primarily of a customer‑related intangible asset, in the accounts of the entity transferred. Prior to 2017, the consolidated financial statements have been retrospectively adjusted to include the results of the Company and its wholly‑owned subsidiary, and the entity under common control on a combined basis, since the entities were under common control.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2—Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements have been prepared in conformity with U.S. GAAP. The consolidated financial statements include the results of the Company and its wholly-owned subsidiary, and an entity under common control that was merged with the Company in April 2017 (Note 1). All significant intercompany accounts and transactions have been eliminated in the consolidation. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fair Value Measurements The Bank utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Bank uses present value techniques and other valuation methods, as disclosed in Note 11, to estimate the fair value of its financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Investment securities available for sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Bank may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as impaired loans, other real estate owned, nonmarketable equity securities and certain other assets and liabilities. These nonrecurring fair value adjustments generally involve write-downs of individual assets or application of lower of amortized cost or fair value accounting. Concentration of Credit Risk The Company's loan portfolio consists primarily of residential real estate loans which are collateralized by real estate. At June 30, 2018 and December 31, 2017, residential real estate loans accounted for 83% and 82%, respectively, of the loan portfolio. In addition, most of these residential loans and other commercial loans have been made to individuals and businesses in the state of California which are dependent on the area economy for their livelihoods and servicing of their loan obligation. At each of June 30, 2018 and December 31, 2017, approximately 95% of the loan portfolio was originated in California. Investment Securities Investment securities includes available for sale debt securities and equity securities. Debt Securities Debt securities are classified as either available for sale or held to maturity. Management determines the classification of the investment securities when they are purchased. Debt securities available for sale are stated at fair value, with unrealized gains and losses excluded from income and shown as a separate component of shareholders' equity in accumulated other comprehensive income, net of tax. Held to maturity securities are carried at amortized cost when management has the positive intent and ability to hold them to maturity. The amortized cost of debt securities classified as held to maturity or available for sale is adjusted for amortization of premiums and accretion of discounts over the contractual life of the investment security using the effective interest method or, in the case of mortgage-backed securities, over the estimated life of the investment security using the effective yield method. Interest income includes amortization or accretion of purchase premium or discount. Gains and losses on sales are recorded on the settlement date and determined using the specific identification method. Management evaluates debt securities for other-than-temporary impairment at least on a quarterly basis and more frequently when economic or market conditions warrant such an evaluation. In determining other-than-temporary impairment for debt securities, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether a decline is other-than-temporary involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. A charge is recognized against income for all or a portion of the impairment if the loss is determined to be other than temporary. If the Bank intends to sell the debt security or it is more likely than not that the Bank will be required to sell the debt security prior to the recovery of its amortized cost basis, the debt security is written down to fair value, and the full amount of any impairment charge is recorded as a loss in the condensed consolidated statements of income. If the Bank does not intend to sell the debt security and it is more likely than not that the Bank will not be required to sell the debt security prior to recovery of its amortized cost basis, only the current period credit loss of any impairment of a debt security is recognized in the condensed consolidated statements of income, with the remaining impairment recorded in other comprehensive income. Equity Securities Beginning January 1, 2018, equity securities with readily determinable fair values are stated at fair value with unrealized and realized gains and losses reported in income. Those equity securities without readily determinable fair values are recorded at cost less any impairments, adjusted for subsequent observable price changes in orderly transactions for an identical or similar investment of the same issuer. Any changes in the carrying value of the equity investments are recognized in income. Refer to Note 3, Investment Securities. For periods prior to January 1, 2018, equity securities were classified as available for sale and stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of tax. The Company performs a qualitative assessment each reporting period to identify impairment. When a qualitative assessment indicates that an impairment exists, the Company determines the fair value of the investment and records an impairment loss equal to the difference between the fair value and the carrying amount of the investment in income. Federal Home Loan Bank Stock The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest additional amounts. The FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. The FHLB stock does not have a readily determinable fair value and no quoted market value as the ownership is restricted to member institutions. Also, the FHLB stock is pledged as collateral on FHLB borrowings. Cash and stock dividends are reported as income in interest and dividends on investment securities in the condensed consolidated statements of income. Cash dividends received amounted $241 and $193 for the three months ended June 30, 2018 and 2017, respectively, and $631 and $389 for the six months ended June 30, 2018 and 2017, respectively. Revenue from Contracts with Customers On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers and all subsequent amendments to the ASU (collectively, “ASC 606”), which establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts to provide goods or services to its customers. The core principle of ASC 606 requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performed obligations are satisfied. The Company adopted ASC 606 using the modified retrospective method applied to all contracts not completed as of the adoption date. The adoption of ASC 606 did not result in a change in the accounting for any of the in-scope revenue streams; as such no cumulative effect adjustment was recorded. The majority of the Company’s revenues are from interest income and other sources, including loans and investment securities, as well as fees related to mortgage servicing activities, that are not within the scope of ASC 606 and are instead subject to other accounting guidance. The Company’s services that are within the scope of ASC 606 are recorded within non-interest income which includes investment management and advisory fees, service charges on deposit accounts, interchange income and other service charges and fees. Descriptions of these activities that are within the scope of ASC 606, which are presented in the condensed consolidated statements of income as components of non-interest income, are as follows: Service charges on deposit accounts: The Bank earns fees from its deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Bank fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Bank satisfies the performance obligations. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposit accounts are withdrawn from the customer’s account balance. Investment management and advisory fees: The Bank enters into contracts with certain customers to provide asset management services that will continue indefinitely unless terminated in writing by either party to the contract. The Bank receives a quarterly management fee, payable in advance, based on the customer’s assets held under management at the beginning of the period. These fees are earned over time as the Bank provides the contracted services and are assessed based on a tiered rate applied to the market value of assets held under management. The Bank does not earn performance-based incentives. Interchange fees: The Bank earns interchange fees from debit cardholder transactions conducted through the MasterCard payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Such interchange activity is shown on a net basis through other non-interest income. Other service charges and fees: Other charges and fees includes revenue generated from wire transfers, lockboxes, and bank issuance of checks. Such fees are recognized at the point in time the customer requests the service and the service has been rendered. The following table presents the Company’s sources of non-interest income for the three and six months ended June 30, 2018 and 2017 that are within the scope of ASC 606: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Non-Interest Income: Service charges on deposit accounts* $ 52 $ 15 $ 104 $ 55 Investment management and advisory fees 500 589 1,123 1,141 Interchange fees* 27 55 52 81 Other service charges and fees* 13 9 20 12 Not within the scope of ASC 606 5,705 862 10,491 5,467 Total non-interest income $ 6,297 $ 1,530 $ 11,790 $ 6,756 * Included in service charges and fees, and other income in the condensed consolidated statements of income Contract Balances The Bank’s noninterest revenue streams are largely based on transactional activity or month-end revenue accruals such as investment management and advisory fees based on the customer’s assets held under management at the beginning of the period. Consideration is often received immediately or shortly thereafter, and the Bank satisfies its performance obligation and recognizes revenue over time. At June 30, 2018 and December 31, 2017, the Bank had a contract asset balance of $40 and $91, respectively, which was recorded in other assets in the condensed consolidated balance sheets. Stock-based compensation Compensation cost is recognized for stock options and restricted stock awards issued to employees and non-employee members of the Company’s Board of Directors, based on the fair value of these awards at the date of grant. The fair value of stock options is estimated using a Black-Scholes option pricing model and the fair value of restricted stock awards is based on the market price of the Company’s common stock at the date of grant reduced by the present value of dividends per share expected to be paid during the period the shares are not vested. Compensation cost is recorded over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recorded on a straight-line basis over the requisite service period of the entire award. The Company’s accounting policy is to record forfeitures in the period that they occur. Income per Share, Basic and Diluted Basic income per share represents net income divided by the weighted average number of common shares outstanding during the period. Diluted income per share represents net income divided by the weighted average number of common shares outstanding during the period, plus the effect of outstanding dilutive potential common shares. Recently Issued Accounting Guidance In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which is intended to improve financial reporting by requiring recording of credit losses on loans and other financial instruments on a more timely basis. The guidance will replace the current incurred loss accounting model with an expected loss approach and requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The guidance requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. ASU No. 2016‑13 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2019. The Company has formed a cross-functional implementation team consisting of individuals from credit, finance and information systems. A project plan has been developed and the implementation team is working on identifying and researching key interpretive issues and is in the process of reviewing existing credit models to identify areas where new impairment models may be required. The Company expects to recognize a cumulative effect adjustment to opening balance of retained earnings as of the beginning of the first reporting period in which ASU No. 2016‑13 is effective. The Company has not yet determined the magnitude of any such one‑time adjustment or the overall impact of ASU No. 2016‑13 on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016‑02, Leases (Topic 842) which require lessees to recognize the following for all leases, except for short‑term leases, at the commencement date: (1) a lease liability which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right‑of‑use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting is largely unchanged. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which provides corrections or clarification on narrow aspects of Topic 842. In July 2018, the FASB also issued ASU 2018-11, Leases (Topic 842): Targeted Improvements , which provides entities with another transition method for adopting the new leasing guidance. As originally issued, ASC 842 requires entities to use a modified restrospective transition approach to apply the new guidance as of the beginning of the earliest period presented in the financial statements in the period adopted. The optional transition method allows entities to apply the new guidance at the adoption date by recognizing a cumulative-effect adjustment to the opening balance of retained earnings, and not to restate the comparative periods presented. ASU No. 2016‑02 will also require expanded disclosures. ASU No. 2016‑02 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018. The Company is currently evaluating the impact of the ASU No. 2016‑02 on its financial condition and results of operations. The Company has identified all of the in-scope leases, and is gathering the respective lease agreements and related data for the new guidance. The Company will record a right‑of‑use asset and a lease liability on its consolidated balance sheet for the leases of its facilities in place at adoption of this ASU.

The proceeds from sales of debt securities available for sale were $2,778 for the three and six months ended June 30, 2018. Gross realized losses on these sales were $3 for the three and six months ended June 30, 2018. The proceeds from sale of debt securities available for sale were $15,713 for the three and six months ended June 30, 2017. The Company recorded gross realized gains of $74 and gross realized losses of $1 on these sales for the three and six months ended June 30, 2017. The amortized cost and fair value of debt securities available for sale issued by U.S. Treasury at June 30, 2018 are shown by contractual maturity. Mortgage-backed securities and collateralized debt obligations are disclosed separately in the table below as the expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties. Amortized Fair Cost Value U.S. Treasury securities Due less than one year $ 136,515 $ 136,377 Collateralized mortgage obligations 1,774 1,837 Collateralized debt obligations 310 301 Total $ 138,599 $ 138,515 The table summarizes debt securities available for sale, at fair value, with unrealized losses at June 30, 2018 and December 31, 2017 aggregated by major security type and length of time the individual securities have been in a continuous unrealized loss position, as follows: June 30, 2018 Less than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized Value Losses Value Losses Value Losses U.S. Treasury securities $ 136,377 $ (138) $ — $ — $ 136,377 $ (138) Collateralized debt obligations — — 301 (9) 301 (9) Total $ 136,377 $ (138) $ 301 $ (9) $ 136,678 $ (147) December 31, 2017 Less than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized Value Losses Value Losses Value Losses U.S. Treasury securities $ 120,042 $ (174) $ — $ — $ 120,042 $ (174) Collateralized debt obligations — — 571 (35) 571 (35) Total $ 120,042 $ (174) $ 571 $ (35) $ 120,613 $ (209) At June 30, 2018, the Company’s debt securities portfolio consisted of 9 debt securities, with 7 debt securities in an unrealized loss position. For debt securities in an unrealized loss position, management has both the intent and ability to hold these investments until the recovery of the decline; thus, the impairment was determined to be temporary. All interest and dividends are considered taxable. The Company holds a collateralized debt obligation with a carrying value of $301 and $571 at June 30, 2018 and December 31, 2017, respectively. The security was rated high quality at inception, but it was subsequently rated by Moody’s as B1, which is defined as “extremely speculative.” The issuers of the security are primarily banks. The Company uses in-house and third party other-than-temporary impairment evaluation models to compare the present value of expected cash flows to the previous estimate to ensure there are no adverse changes in cash flows during the period. The other-than-temporary impairment model considers the structure and term of the collateralized debt obligations and the financial condition of the underlying issuers. Assumptions used in the model include expected future default rates and prepayments. The security remained classified as available for sale and represented $9 and $35 of the unrealized losses reported at June 30, 2018 and December 31, 2017, respectively. Equity Securities Equity securities consist of an investment in a qualified community reinvestment act investment fund, which is a publicly-traded mutual fund and an investment in Pacific Coast Banker’s Bank, a thinly traded, restricted stock. At June 30, 2018 and December 31, 2017, equity securities totaled $4,133 and $4,227, respectively. Prior to January 1, 2018, equity securities were stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of tax. On January 1, 2018, the Company adopted ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”) and early adopted ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2018-03”) . ASU No. 2016-01 requires equity investments, except those investments accounted for under the equity method of accounting, to be measured at fair value with changes in fair value recognized in net income. Also, for equity investments without readily determinable fair values, ASU No.2016-01 provides a new measurement alternative. ASU No. 2016-01 requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption to reclassify the cumulative change in fair value of equity securities previously recognized in accumulated other comprehensive income. ASU No. 2018-03 clarifies certain aspects of the guidance in ASU No. 2016-01 primarily pertaining to the measurement alternative for equity securities without readily determinable fair values. On January 1, 2018, the Company recorded a cumulative-effect adjustment to decrease retained earnings by $50 with offsetting adjustment to accumulated other comprehensive loss. Beginning January 1, 2018, equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in income. At June 30, 2018 and December 31, 2017, equity securities with readily determinable fair values were $3,887 and $3,981, respectively. The following is a summary of unrealized and realized gains and losses recognized in the condensed consolidated statements of income during the three and six months ended June 30, 2018: Three Months Six Months Ended Ended June 30, 2018 June 30, 2018 Net losses recorded during the period on equity securities $ (30) $ (94) Less: net losses recorded during the period on equity securities sold during the period — — Unrealized losses recorded during the period on equity securities held at the reporting date $ (30) $ (94) The Company has elected to account for its investment in a thinly traded, restricted stock using the measurement alternative for equity securities without readily determinable fair values. The investment was reported at $246 at each of June 30, 2018 and December 31, 2017.

When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual status, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan is not in doubt and the loan is on nonaccrual status, contractual interest is credited to interest income when received under the cash basis method. The average balances are calculated based on the month-end balances of the loans for the period reported.

For residential real estate and consumer loan classes, the Company also evaluates credit quality based on the aging status of the loan, which is presented above, and by payment activity. The Company reviews the status of nonperforming loans which include loans 90 days past due and still accruing and nonaccrual loans. Troubled Debt Restructurings At June 30, 2018 and December 31, 2017, the balance of outstanding loans identified as troubled debt restructurings was $3,011 and $3,073, respectively. The Company has an allowance for loan losses of $109 and $56 on these loans at June 30, 2018 and December 31, 2017, respectively. There were no loans identified as troubled debt restructurings that subsequently defaulted. The terms of certain loans have been modified as troubled debt restructurings by the Company. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; extension of the amortization period of the loan; change in loan payments to interest only for a defined period for the loan; or a permanent reduction of the recorded investment in the loan. During the six months ended June 30, 2018 and 2017, the Company did not modify any loans as a troubled debt restructuring. The terms of certain other loans have been modified during the six months ended June 30, 2018 and 2017 that did not meet the definition of a troubled debt restructuring. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment. These other loans that were modified were not considered significant. Credit Quality The Company categorizes loans 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 analyzes loans individually by classifying the loans as to credit risk. This analysis includes homogeneous loans such as residential real estate and consumer loans and non-homogeneous loans, such as commercial lines of credit, construction and commercial real estate loans. This analysis is performed monthly. The Company uses the following definitions for risk ratings: Pass: Loans are of satisfactory quality. Special Mention: Loans 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 of the Company’s credit position at some future date. Substandard: Loans 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 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 Company will sustain some loss if the deficiencies are not corrected. Doubtful: Loans 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, based on currently existing facts, conditions, and values, highly questionable and improbable. At June 30, 2018 and December 31, 2017, the risk rating of loans by class of loans was as follows: Special June 30, 2018 Pass Mention Substandard Doubtful Total Construction $ 155,310 $ 5,959 $ 10,993 $ — $ 172,262 Residential real estate: Residential first mortgage 2,348,516 — 62 504 2,349,082 Residential second mortgage 18,794 — — — 18,794 Commercial real estate: Retail 9,021 — 1,211 — 10,232 Apartments 64,637 — — — 64,637 Offices 28,140 — — — 28,140 Hotel 103,378 — — — 103,378 Industrial 14,882 — — — 14,882 Gas stations 1,012 — — — 1,012 Other 26,009 475 1,700 — 28,184 Commercial lines of credit: Private banking 27,374 — 186 — 27,560 C&I lending 17,308 853 100 — 18,261 Other consumer loans 32 — — — 32 Total $ 2,814,413 $ 7,287 $ 14,252 $ 504 $ 2,836,456 Special December 31, 2017 Pass Mention Substandard Doubtful Total Construction $ 177,241 $ 11,670 $ 3,408 $ — $ 192,319 Residential real estate: Residential first mortgage 2,114,511 — 109 520 2,115,140 Residential second mortgage 17,501 — — — 17,501 Commercial real estate: Retail 9,363 1,167 79 — 10,609 Apartments 58,472 1,110 — — 59,582 Offices 26,571 — — — 26,571 Hotel 103,195 — — — 103,195 Industrial 15,907 — — — 15,907 Gas stations 1,067 — — — 1,067 Other 24,741 4,733 671 — 30,145 Commercial lines of credit: Private banking 22,702 — 196 — 22,898 C&I lending 17,851 — — — 17,851 Other consumer loans 29 — — — 29 Total $ 2,589,151 $ 18,680 $ 4,463 $ 520 $ 2,612,814 The Bank sold pools of residential real estate mortgages for $157.5 million and $17.9 million during the three months ended June 30, 2018 and 2017, respectively, and $269.7 million and $123.1 million during the six months ended June 30, 2018 and 2017, respectively, to third-party investors. The transactions resulted in full derecognition of the mortgages (i.e. transferred assets) from the condensed consolidated balance sheets and recognition of gain on sale of portfolio loans of $5.1 million and $0.6 million for the three months ended June 30, 2018 and 2017, respectively, and $9.0 million and $4.4 million for the six months ended June 30, 2018 and 2017, respectively. After the sales, the Bank’s only continuing involvement in the transferred assets is to act as servicer of the mortgages.

Residential real estate mortgage loans serviced for others are not included in the condensed consolidated balance sheets. The principal balance of these loans at June 30, 2018 and December 31, 2017 are as follows: June 30, December 31, 2018 2017 Residential real estate mortgage loan portfolios serviced for: FNMA $ 76,404 $ 73,039 FHLB 92,500 92,697 Private investors 627,916 442,984 Custodial escrow balances maintained with these serviced loans were $15,850 and $11,944 at June 30, 2018 and December 31, 2017, respectively. Activity for mortgage servicing rights and the related valuation allowance are as follows: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Mortgage servicing rights: Beginning of period $ 7,801 $ 5,454 $ 6,706 $ 4,454 Additions 2,066 287 3,587 1,547 Amortization (554) (442) (980) (702) End of period 9,313 5,299 9,313 5,299 Valuation allowance at beginning of period 21 30 210 40 Additions (recoveries) (3) 90 (192) 80 Valuation allowance at end of period 18 120 18 120 Mortgage servicing rights, net $ 9,295 $ 5,179 $ 9,295 $ 5,179 Mortgage servicing assets were $9,295 and $6,496 at June 30, 2018 and December 31, 2017, respectively. Servicing fee income (expense), net of amortization of servicing rights and changes in the valuation allowance, was $233 and $(48) for the three months ended June 30, 2018 and 2017, respectively, and $710 and $121 for the six months ended June 30, 2018 and 2017, respectively, and were included in other non-interest income in the condensed consolidated statements of income. The fair value of mortgage servicing rights was $10,855 and $7,086 at June 30, 2018 and December 31, 2017, respectively. The fair value of mortgage servicing rights is highly sensitive to changes in underlying assumptions. Changes in prepayment speed assumptions have the most significant impact on the estimate of the fair value of mortgage servicing rights. The fair value at June 30, 2018 was determined using discount rates ranging from 9.5% to 12.0%, prepayment speeds ranging from 6.8% to 29.2%, depending on the stratification of the specific right, and a weighted average default rate of 0.2%. The fair value at December 31, 2017 was determined using discount rates ranging from 9.5% to 12.0%, prepayment speeds ranging from 6.8% to 36.0%, depending on the stratification of the specific right, and a weighted average default rate of 0.2%.

The long-term fixed rate advances have maturity dates ranging from July 2019 to October 2026. Interest on these advances is payable monthly and each advance is payable at its maturity date, and may contain a prepayment penalty if paid before maturity. At June 30, 2018, advances totaling $157,000 were callable by the FHLB as follows: $67,000 in September 2021 and $90,000 in October 2021. At June 30, 2018, the Bank had additional borrowing capacity of $331.8 million from the FHLB. FHLB Overdraft Line of Credit The Bank has established an overdraft line of credit agreement with the FHLB providing maximum borrowings of $50,000. The average amount outstanding was $4,511 and $14,597 during the six months ended June 30, 2018 and 2017, respectively. At June 30, 2018 and December 31, 2017, there were no outstanding borrowings under this agreement. Borrowings accrue interest based on a variable rate based on the FHLB’s overnight cost of funds rate, which was 2.26% and 1.67% at June 30, 2018 and December 31, 2017, respectively. The agreement has a one ‑year term and terminates in October 2018. The FHLB advances and the overdraft line of credit are collateralized by pledged loans totaling $953.7 million at June 30, 2018. Other Borrowings The Company had available credit lines with other banks totaling $60 million. There were no amounts outstanding under these credit lines at June 30, 2018 and December 31, 2017.

Issuance costs of $729 were netted against the proceeds. In August 2017, the Company issued an additional $15 million in aggregate principal amount of subordinated notes to accredited investors. The terms of the subordinated note purchase agreements were substantially identical to the subordinated notes that were previously issued in 2016 (collectively, “Notes”), except that the first interest payment on the subordinated notes included accrued interest from April 15, 2017. The Company recorded a premium of $611 and debt issuance costs of $191 upon issuance of the notes. The Notes bear interest at 7% per annum, payable semi‑annually on April 15 and October 15 in arrears, through April 2021 after which the Notes will have a variable interest rate of the three‑month LIBOR rate plus a margin of 5.82%. Premiums and debt issuance costs are amortized over the contractual term of the Notes into interest expense using the effective interest method. Interest expense on these Notes was $1,171 and $908 for the three months ended June 30, 2018 and 2017, respectively, and $2,343 and $1,816 for the six months ended June 30, 2018 and 2017, respectively. The Notes mature in April 2026. On or after April 14, 2021, the Company may redeem the Notes, in whole or in part, at an amount equal to 100% of the outstanding principal amount being redeemed plus accrued interest, in a principal amount with integral multiples of $1. The Notes are not redeemable by the Company prior to April 14, 2021 except in the event of (i) the Notes no longer qualify as Tier 2 Capital, (ii) the interest on the Notes is determined by law to be not deductible for Federal Income Tax reporting or (iii) the Company is considered an investment company pursuant to the Investment Company Act of 1940. The Notes are not subject to redemption by the noteholder. The Notes are unsecured obligations and are subordinated in right of payment to all existing and future indebtedness, deposits and other liabilities of the Company’s current and future subsidiaries, including the Bank’s deposits as well as the Company’s subsidiaries liabilities to general creditors and liabilities arising during the ordinary course of business. The Notes may be included in Tier 1 capital of the Bank and Tier 2 capital for the Company under current regulatory guidelines and interpretations. As long as the Notes are outstanding, the Company is permitted to pay dividends if prior to such dividends, the Bank is considered well capitalized, as defined in Note 13, Regulatory Capital Requirements.

Stock-based Compensation
Stock-based Compensation	Note 9—Stock-based Compensation The Board of Directors established a 2017 Omnibus Equity Incentive Plan (“Plan”) which was approved by the shareholders in October 2017. The Plan provides for the grant of up to 4,237,100 shares of common stock for stock options, stock appreciation rights, restricted stock, restricted stock units and other stock-based awards for issuance to employees, consultants and Board of Directors of the Company. The stock-based awards are issued at no less than the market price on the date the awards are granted. Stock Options Stock option awards are granted with an exercise price equal to the market price of the Company’s common stock on the date of grant. The stock option awards generally vest in installments of 50% in each of the third and fourth year after the date of grant and have a maximum term of ten years. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option pricing model that uses the assumptions noted below. Estimating the grant date fair values for employee stock options requires management to make assumptions regarding expected volatility of the value of those underlying shares, the risk-free rate over the expected life of the stock options and the date on which share-based payments will be settled. Expected volatilities are based on a weighted average of the Company’s historic volatility and an implied volatility for a group of industry-relevant bank holding companies as of the measurement date. The expected term of options granted is calculated using the simplified method (the midpoint between the end of the vesting period and the end of the maximum term). The risk-free rate for the expected term of the option is based upon U.S. Treasury yield curve in effect at the time of grant. Expected dividend yield represents what the Company anticipates will be declared during the expected term of the options. On March 21, 2018, the Board of Directors approved the issuance of options to purchase 92,625 shares of common stock with an exercise price of $13.73 to certain key employees which are accounted for as equity awards. These options to purchase shares of common stock had a weighted average grant-date fair value of $4.56 per option. The grant-date fair value of each stock option award was estimated using the Black-Scholes option pricing model that uses the assumptions set forth in the following table: Exercise price of options $ 13.73 Risk-free interest rate 2.80 % Expected term (in years) 6.75 Expected stock price volatility 23.7 % Dividend yield .29 % A summary of the Company’s stock option activity as of and for the six months ended June 30, 2018 is as follows: Weighted Weighted Average Average Remaining Aggregate Number Exercise Contractual Intrinsic of Shares Price Term Value (Years) Outstanding at January 1, 2018 — $ — — $ — Granted 92,625 13.73 Exercised — — Forfeited/expired — — Outstanding at June 30, 2018 92,625 $ 13.73 9.72 $ — The Company recorded share-based compensation expense associated with stock options of $26 and $29 for the three and six months ended June 30, 2018, respectively. At June 30, 2018, there was $393 of total unrecognized compensation cost related to nonvested stock options granted under the Plan. The cost is expected to be recognized over a weighted-average period of 3.72 years. No options are exercisable at June 30, 2018. Restricted Stock Awards The value of a restricted stock award is based on the market value of the Company’s common stock at the date of grant reduced by the present value of dividends per share expected to be paid during the period the shares are not vested. On March 21, 2018, the Board of Directors approved the issuance of 39,655 restricted stock awards to certain key employees and non-employee directors. The restricted stock awards of 33,100 issued to key employees vest in installments of 50% in each of the third and fourth year after the date of grant. The 6,555 restricted stock awards issued to non-employee directors vest on the first anniversary of the grant date. The restricted stock awards were issued with a weighted average grant-date fair value of $13.60. Upon a change in control, as defined in the Plan, the outstanding restricted stock awards will immediately vest. The fair value of the award is recorded as compensation expense on a straight-line basis over the vesting period. The Company recorded share-based compensation expense associated with restricted stock awards of $50 and $56 for the three and six months ended June 30, 2018, respectively. At June 30, 2018, there was $484 of total unrecognized compensation cost related to the nonvested stock granted under the Plan. The cost is expected to be recognized over a weighted-average period of 3.32 years.

Income Per Share	Note 10— Income Per Share Basic income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted income per common share further includes any common shares available to be issued upon the exercise of outstanding stock options and restricted stock awards if such inclusions would be dilutive. The Company determines the potentially dilutive common shares using the treasury stock method. The following table presents the computation of income per share, basic and diluted: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Numerator: Net income $ 15,982 $ 8,938 $ 31,731 $ 19,354 Denominator: Weighted average common shares outstanding, basic 52,963,308 45,271,000 52,963,308 45,271,000 Weighted average effect of potentially dilutive common shares: Stock options — — — — Restricted stock 2,057 — 1,825 — Weighted average common shares outstanding, diluted 52,965,365 45,271,000 52,965,133 45,271,000 Income per share: Basic $ 0.30 $ 0.20 $ 0.60 $ 0.43 Diluted $ 0.30 $ 0.20 $ 0.60 $ 0.43 The effect of 92,625 options to purchase shares of common stock were excluded in computing diluted income per common share for the three and six months ended June 30, 2018, as the inclusion would be antidilutive. In September 2017, the Board of Directors approved a 1,000 for one stock split to be effected as a stock dividend on the Company’s common stock. The stock split was effected on September 11, 2017. All share and per share amounts have been retroactively adjusted to reflect the stock split for the three and six months ended June 30, 2017.

Fair Values of Financial Instruments
Fair Values of Financial Instruments	Note 11—Fair Values of Financial Instruments The Company's financial instruments include assets carried at fair value, as well as certain assets and liabilities carried at cost or amortized cost but disclosed at fair value in these condensed consolidated financial statements. Fair value is defined as the exit price, the price that would be received for an asset or paid to transfer a liability in the principal most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. The inputs to valuation techniques used to measure fair value are prioritized into a three-level hierarchy. The hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate the fair value of investment securities and impaired loans: Investment Securities The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar investment securities (Level 2). For investment securities where quoted prices or market prices of similar investment securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). Discounted cash flows are calculated using spread to LIBOR curves that are updated to incorporate loss severities, volatility, credit spread and optionality. During times when trading is more liquid, broker quotes are used (if available) to validate the model. Rating agency and industry research reports as well as defaults and deferrals on individual investment securities are reviewed and incorporated into the calculations. Impaired Loans The fair value of collateral dependent impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Assets Measured at Fair Value on a Recurring Basis The table below presents the assets measured at fair value on a recurring basis categorized by the level of inputs used in the valuation of each asset at June 30, 2018 and December 31, 2017: Fair Value Measurements at June 30, 2018 Quoted Prices Significant in Active Other Significant Markets for Observable Unobservable Identical Assets Inputs Inputs Total (Level 1) (Level 2) (Level 3) Financial Assets Available for sale debt securities: U.S. Treasury securities $ 136,377 $ 136,377 $ — $ — Collateralized mortgage obligations 1,837 — 1,837 — Collateralized debt obligations 301 — — 301 Equity securities 3,887 3,887 — — Fair Value Measurements at December 31, 2017 Quoted Prices Significant in Active Other Significant Markets for Observable Unobservable Identical Assets Inputs Inputs Total (Level 1) (Level 2) (Level 3) Financial Assets Available for sale debt securities: U.S. Treasury securities $ 120,042 $ 120,042 $ — $ — Collateralized mortgage obligations 2,008 — 2,008 — Collateralized debt obligations 571 — — 571 Equity securities 4,227 3,981 — 246 * * The Company has elected to account for its investment in a thinly traded, restricted stock with a carrying value of $246 using the measurement alternative for equity securities without a readily determinable fair value therefore, the investment is excluded from the fair value measurement disclosures at June 30, 2018. There were no transfers between Level 1 and Level 2 during 2018 or 2017.

In addition to the amounts included in income for the six months ended June 30, 2018 as presented in the table above, the Company also recorded interest income on collateralized debt obligations of $9. Unrealized losses on Level 3 investments for collateralized debt obligations and equity securities at December 31, 2017 were $35 and $0, respectively. In addition to the amounts included in income for the year ended December 31, 2017 as presented in the table above, the Company also recorded interest income on collateralized debt obligations of $21 and dividend income on equity securities of $15. The fair value of collateralized debt obligations is determined by calculating discounted cash flows using LIBOR curves plus spreads that adjust for loss severities, volatility, credit risk and optionality. When available, broker quotes are used to validate the internal model. Rating agency and industry research reports as well as assumptions about specific-issuer defaults and deferrals are reviewed and incorporated into the calculations. Assumptions are reviewed on a quarterly basis as specific-issuer deferral and defaults that occurred are compared to those that were projected and ongoing assumptions are adjusted in accordance with the level of unexpected deferrals and defaults that occurred. The following table presents quantitative information about recurring Level 3 fair value measurements at June 30, 2018 and December 31, 2017: Fair Value Valuation Technique Unobservable Inputs June 30, 2018 Collateralized debt obligations $ 301 Discounted cash flow Collateral default rate 0 % Recovery probability 15 % December 31, 2017 Collateralized debt obligations $ 571 Discounted cash flow Collateral default rate 0 % Recovery probability 15 % The significant unobservable inputs used on the fair value measurement of the Company’s collateralized debt obligations are probabilities of specific-issuer defaults and specific-issuer recovery assumptions. Significant increases in specific-issuer default assumptions or decreases in specific-issuer recovery assumptions would result in a significantly lower fair value measurement. Conversely, decreases in specific-issuer default assumptions or increases in specific-issuer recovery assumptions would result in a significantly higher fair value measurement. Assets Measured at Fair Value on a Non‑Recurring Basis From time to time, the Bank may be required to measure certain other assets at fair value on a nonrecurring basis in accordance with U.S. GAAP. These adjustments to fair value usually result from the application of lower of cost or fair value accounting or write‑downs of individual assets. For assets measured at fair value on a nonrecurring basis which were still held in the condensed consolidated balance sheet at June 30, 2018, the following table provides the level of valuation assumptions used to determine each adjustment and the related carrying value: Fair Value Measurements at June 30, 2018 Quoted Prices Significant in Active Other Significant Markets for Observable Unobservable Carrying Idential Assets Inputs Inputs Value (Level 1) (Level 2) (Level 3) Impaired loans, construction $ 2,556 $ — $ — $ 2,556 At June 30, 2018, impaired loans had a loan amount of $2,761 with a valuation allowance of $205, resulting in an addition to provision for loan losses of $205 for the three and six months ended June 30, 2018. As discussed previously, the fair values of collateral dependent impaired loans carried at fair value are determined by third-party appraisals. Management adjusts these appraised values based on the age of the appraisal and the type of the property.

The Company is not required to revise its prior-period disclosures of fair value for those financial instruments that may have been calculated using the entry price notion, which was acceptable prior to January 1, 2018. Therefore, the prior-period fair values disclosed may not be determined in a manner consistent with the current-period fair values disclosed because of a change in methodology. The carrying amounts and estimated fair values of financial instruments not carried at fair value at June 30, 2018 and December 31, 2017, are as follows: Fair Value Measurements at June 30, 2018 Carrying Amount Fair Value Level 1 Level 2 Level 3 Financial Assets Cash and due from banks $ 36,820 $ 36,820 $ 36,820 $ — $ — Mortgage loans held for sale 21,641 21,996 — 21,996 — Loans, net 2,813,600 2,874,500 — — 2,874,500 Financial Liabilities Time deposits 748,179 745,832 — 745,832 — Federal Home Loan Bank borrowings 350,000 339,495 — 339,495 — Subordinated notes, net 64,958 66,950 — 66,950 — Fair Value Measurements at December 31, 2017 Carrying Amount Fair Value Level 1 Level 2 Level 3 Financial Assets Cash and due from banks $ 40,147 $ 40,147 $ 40,147 $ — $ — Mortgage loans held for sale 112,866 115,619 — 115,619 — Loans, net 2,594,357 2,635,986 — — 2,635,986 Financial Liabilities Time deposits 663,472 660,380 — 660,380 — Federal Home Loan Bank borrowings 338,000 330,004 — 330,004 — Subordinated notes, net 64,889 67,485 — 67,485 —

Income Taxes	Note 12—Income Taxes The Tax Cut and Jobs Act (the "Tax Act") enacted in December 2017 reduced the federal corporate income tax rate from 35% to 21%, effective January 1, 2018. Due to the change in tax rate, the Company was required to remeasure its deferred tax assets and liabilities, including the deferred tax balance attributable to items of pretax comprehensive income (loss), based on the rates at which they are expected to reverse in the future. The effect of the Tax Act of $3.3 million was recorded in deferred income tax expense in the fourth quarter and year ended December 31, 2017 which related entirely to the remeasurement of the net deferred tax asset. The Company has implemented the new corporate tax rate as of January 1, 2018. The reconciliation of the U.S. federal statutory tax rate to the Company's effective tax rate is as follows: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 U.S. federal statutory rate 21.0 % 35.2 % 21.0 % 35.1 % Effect of: State taxes, net of federal benefit 7.8 % 5.9 % 7.8 % 6.0 % Loss incurred by pass- through entity — — — 0.4 % Income on cash surrender value of bank- owned life insurance (0.2) % (0.4) % (0.2) % (0.4) % Effective tax rate 28.6 % 40.7 % 28.6 % 41.1 %

Regulatory Capital Requirements

Regulatory Capital Requirements
Regulatory Capital Requirements	Note 13—Regulatory Capital Requirements The Bank is subject to the capital adequacy requirements of the OCC. The Company, as a thrift holding company, is subject to the capital adequacy requirements of the Federal Reserve. Capital adequacy guidelines and prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off‑balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings, and other factors, and the regulators can lower classifications in certain cases. Prompt corrective action provisions are not applicable to thrift holding companies. Failure to meet minimum capital requirements can initiate regulatory action that could have a direct material effect on the consolidated financial statements. The final rules implementing Basel III became effective on January 1, 2015 with full compliance with all requirements being phased in over a multi‑year schedule, and fully phased in by January 1, 2019. Under the Basel III rules, the Company must hold a capital conservation buffer over the adequately capitalized risk‑based capital ratios. The capital conservation buffer is being phased in from 0.0% for 2015 to 2.50% by 2019. The capital conservation buffer is 1.875% for 2018. The net unrealized gain or loss on investment securities is not included in regulatory capital. Management believes that as of June 30, 2018, the Company and the Bank meet all regulatory capital requirements to which they are subject. Management also expects that the Company and the Bank will be fully compliant with all requirements being phased in by January 1, 2019. Prompt corrective action regulations provide five classifications, including well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. The minimum requirements, excluding significantly undercapitalized and critically undercapitalized categories, are as follows: Capital Tier 1 Weighted Capital to Common Assets Average Tier 1 Total Tier 1 Assets (CET1) Well Capitalized 10.0 % 8.0 % 5.0 % 6.5 % Adequately Capitalized 8.0 % 6.0 % 4.0 % 4.5 % Undercapitalized 6.0 % 4.0 % 3.0 % 3.0 % At June 30, 2018, the most recent regulatory notifications categorized the Bank as well capitalized. There have been no conditions or events since these notifications that management believes would have changed the Bank’s category. At June 30, 2018 and December 31, 2017, the Bank exceeded all capital requirements to be categorized as well capitalized and the Company exceeded the capital adequacy requirements as presented below. The Company and the Bank’s actual and minimum required capital amounts and ratios, with such regulatory minimums not including the capital conservation buffer, at June 30, 2018 and December 31, 2017 are as follows: For Capital To be Well Actual Adequacy Purposes Capitalized Amount Ratio Amount Ratio Amount Ratio June 30, 2018 Total adjusted capital to risk weighted assets Consolidated $ 388,759 20.77 % $ 149,734 8.00 % N/A N/A Bank 292,056 15.60 149,732 8.00 $ 187,164 10.00 % Tier 1 (core) capital to risk weighted assets Consolidated 303,502 16.21 112,301 6.00 N/A N/A Bank 271,756 14.52 112,299 6.00 149,732 8.00 Common Tier 1 (CET1) Consolidated 303,502 16.21 84,226 4.50 N/A N/A Bank 271,756 14.52 84,224 4.50 121,657 6.50 Tier 1 (core) capital to adjusted tangible assets Consolidated 303,502 9.88 122,907 4.00 N/A N/A Bank 271,756 8.84 122,905 4.00 153,631 5.00 For Capital To be Well Actual Adequacy Purposes Capitalized Amount Ratio Amount Ratio Amount Ratio December 31, 2017 Total adjusted capital to risk weighted assets Consolidated $ 365,078 20.28 % $ 140,447 8.00 % N/A N/A Bank 259,165 14.76 140,447 8.00 $ 175,559 10.00 % Tier 1 (core) capital to risk weighted assets Consolidated 272,732 15.53 105,336 6.00 N/A N/A Bank 240,708 13.71 105,336 6.00 140,447 8.00 Common Tier 1 (CET1) Consolidated 272,732 15.53 79,002 4.50 N/A N/A Bank 240,708 13.71 79,002 4.50 114,114 6.50 Tier 1 (core) capital to adjusted tangible assets Consolidated 272,732 9.83 110,949 4.00 N/A N/A Bank 240,708 8.68 110,949 4.00 138,687 5.00 Dividend Restrictions As noted above, banking regulations require the Bank to maintain certain capital levels and may limit the dividends paid by the bank to the holding company or by the holding company to its shareholders. The Company’s principal source of funds for dividend payments is dividends received from the Bank and banking regulations limit the dividends that may be paid. Also, pursuant to the terms of the subordinated note agreements, the Company may pay dividends if it is “well capitalized” as defined by regulatory guidelines. At June 30, 2018, $149.9 million of consolidated retained earnings were available to pay dividends to the Company’s shareholders. The Qualified Thrift Lender (“QTL”) test requires that a minimum of 65% of assets be maintained in housing‑related finance and other specified areas. If the QTL test is not met, limits are placed on growth, branching, new investments, FHLB Advances and dividends, or the Bank must convert to a commercial bank charter. Management believes that the QTL test has been met.

Related Party Transactions	Note 14—Related Party Transactions As disclosed in Note 1, the Company purchased an entity owned 80% by its principal shareholder and 20% by a member of the Board of Directors of the Company and Bank. At the time of the purchase in April 2017, the Director was and will continue as the Chief Executive Officer (“CEO”) of the purchased entity. For the six months ended June 30, 2017, the consolidated statements of income include compensation‑related expenses of $125 for the Director’s services as CEO of this purchased entity. From time to time, the Company makes charitable contributions to a foundation which certain members of the Board of Directors of the Company and Bank, and whom are also related to the Company’s principal shareholders, serve as trustees of the foundation. The Company paid $225 to the foundation during the three months ended June 30, 2018 and 2017, and $450 during the six months ended June 30, 2018 and 2017. The Bank leases certain storage and office space from entities owned by the Company’s principal shareholders. Amounts paid under such leases totaled $17 and $10 during the three months ended June 30, 2018 and 2017, respectively, and $34 and $19 during the six months ended June 30, 2018 and 2017, respectively. The Bank provides monthly data processing and programming services to entities controlled by the Company’s principal shareholders. Aggregate fees paid amounted to $29 and $21 during the three months ended June 30, 2018 and 2017, respectively, and $54 and $48 during the six months ended June 30, 2018 and 2017, respectively.

Commitments and Contingencies
Commitments and Contingencies	Note 15—Commitments and Contingencies Legal Proceedings The Company and its subsidiaries may be subject to legal actions and claims arising from contracts or other matters from time to time in the ordinary course of business. Management is not aware of any pending or threatened litigation where the ultimate disposition or resolution could have a material adverse effect on its financial position, results of operations or liquidity. Lease Commitments The Company leases its corporate headquarters and branch offices through noncancelable operating leases with terms that range from years 2019 to 2029, with renewal options thereafter. Rent expense was $948 and $875 for the three months ended June 30, 2018 and 2017, respectively, and $1,869 and $1,700 for the six months ended June 30, 2018 and 2017, respectively. Financial Instruments with Off-Balance Sheet Risk The Bank is a party to financial instruments with off-balance risk in the normal course of business to meet the financial needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit which are not reflected in the consolidated financial statements. Unfunded Commitments to Extend Credit A commitment to extend credit, such as a loan commitment, credit line and overdraft protection, is a legally binding agreement to lend funds to a customer, usually at a stated interest rate and for a specific purpose. Such commitments have fixed expiration dates and generally require a fee. The extension of a commitment gives rise to credit risk. The actual liquidity requirements or credit risk that the Bank will experience is expected to be lower than the contractual amount of commitments to extend credit because a significant portion of those commitments are expected to expire without being drawn upon. Certain commitments are subject to loan agreements containing covenants regarding the financial performance of the customer that must be met before the Bank is required to fund the commitment. The Bank uses the same credit policies in making commitments to extend credit as it does in making loans. The commitments outstanding to make loans include primarily residential real estate loans that are made for a period of 90 days or less. At June 30, 2018, outstanding commitments to make loans consisted of fixed rate loans of $9,220 with interest rates ranging from 3.875% to 7.25% and maturities ranging from 10 years to 30 years and variable rate loans of $246,718 with varying interest rates (ranging from 3.875% to 7.50% at June 30, 2018) and maturities ranging from 2 to 30 years. Standby Letters of Credit Standby letters of credit are issued on behalf of customers in connection with construction contracts between the customers and third parties. Under standby letters of credit, the Bank assures that the third parties will receive specified funds if customers fail to meet their contractual obligations. The credit risk to the Bank arises from its obligation to make payment in the event of a customer’s contractual default. The maximum amount of potential future payments guaranteed by the Bank is limited to the contractual amount of these letters. Collateral may be obtained at exercise of the commitment. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. The following is a summary of the total amount of unfunded commitments to extend credit and standby letters of credit outstanding at June 30, 2018 and December 31, 2017: June 30, December 31, 2018 2017 Commitments to make loans $ 255,938 $ 268,401 Unused lines of credit 166,825 157,234 Standby letters of credit 70 70

Summary of Significant Accoun26

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Summary of Significant Accounting Policies
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements have been prepared in conformity with U.S. GAAP. The consolidated financial statements include the results of the Company and its wholly-owned subsidiary, and an entity under common control that was merged with the Company in April 2017 (Note 1). All significant intercompany accounts and transactions have been eliminated in the consolidation.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value Measurements	Fair Value Measurements The Bank utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Bank uses present value techniques and other valuation methods, as disclosed in Note 11, to estimate the fair value of its financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Investment securities available for sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Bank may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as impaired loans, other real estate owned, nonmarketable equity securities and certain other assets and liabilities. These nonrecurring fair value adjustments generally involve write-downs of individual assets or application of lower of amortized cost or fair value accounting.
Concentration of Credit Risk	Concentration of Credit Risk The Company's loan portfolio consists primarily of residential real estate loans which are collateralized by real estate. At June 30, 2018 and December 31, 2017, residential real estate loans accounted for 83% and 82%, respectively, of the loan portfolio. In addition, most of these residential loans and other commercial loans have been made to individuals and businesses in the state of California which are dependent on the area economy for their livelihoods and servicing of their loan obligation. At each of June 30, 2018 and December 31, 2017, approximately 95% of the loan portfolio was originated in California.
Investment Securities	Investment Securities Investment securities includes available for sale debt securities and equity securities. Debt Securities Debt securities are classified as either available for sale or held to maturity. Management determines the classification of the investment securities when they are purchased. Debt securities available for sale are stated at fair value, with unrealized gains and losses excluded from income and shown as a separate component of shareholders' equity in accumulated other comprehensive income, net of tax. Held to maturity securities are carried at amortized cost when management has the positive intent and ability to hold them to maturity. The amortized cost of debt securities classified as held to maturity or available for sale is adjusted for amortization of premiums and accretion of discounts over the contractual life of the investment security using the effective interest method or, in the case of mortgage-backed securities, over the estimated life of the investment security using the effective yield method. Interest income includes amortization or accretion of purchase premium or discount. Gains and losses on sales are recorded on the settlement date and determined using the specific identification method. Management evaluates debt securities for other-than-temporary impairment at least on a quarterly basis and more frequently when economic or market conditions warrant such an evaluation. In determining other-than-temporary impairment for debt securities, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether a decline is other-than-temporary involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. A charge is recognized against income for all or a portion of the impairment if the loss is determined to be other than temporary. If the Bank intends to sell the debt security or it is more likely than not that the Bank will be required to sell the debt security prior to the recovery of its amortized cost basis, the debt security is written down to fair value, and the full amount of any impairment charge is recorded as a loss in the condensed consolidated statements of income. If the Bank does not intend to sell the debt security and it is more likely than not that the Bank will not be required to sell the debt security prior to recovery of its amortized cost basis, only the current period credit loss of any impairment of a debt security is recognized in the condensed consolidated statements of income, with the remaining impairment recorded in other comprehensive income. Equity Securities Beginning January 1, 2018, equity securities with readily determinable fair values are stated at fair value with unrealized and realized gains and losses reported in income. Those equity securities without readily determinable fair values are recorded at cost less any impairments, adjusted for subsequent observable price changes in orderly transactions for an identical or similar investment of the same issuer. Any changes in the carrying value of the equity investments are recognized in income. Refer to Note 3, Investment Securities. For periods prior to January 1, 2018, equity securities were classified as available for sale and stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of tax. The Company performs a qualitative assessment each reporting period to identify impairment. When a qualitative assessment indicates that an impairment exists, the Company determines the fair value of the investment and records an impairment loss equal to the difference between the fair value and the carrying amount of the investment in income.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest additional amounts. The FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. The FHLB stock does not have a readily determinable fair value and no quoted market value as the ownership is restricted to member institutions. Also, the FHLB stock is pledged as collateral on FHLB borrowings. Cash and stock dividends are reported as income in interest and dividends on investment securities in the condensed consolidated statements of income. Cash dividends received amounted $241 and $193 for the three months ended June 30, 2018 and 2017, respectively, and $631 and $389 for the six months ended June 30, 2018 and 2017, respectively.
Revenue from Contracts with Customers	Revenue from Contracts with Customers On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers and all subsequent amendments to the ASU (collectively, “ASC 606”), which establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts to provide goods or services to its customers. The core principle of ASC 606 requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performed obligations are satisfied. The Company adopted ASC 606 using the modified retrospective method applied to all contracts not completed as of the adoption date. The adoption of ASC 606 did not result in a change in the accounting for any of the in-scope revenue streams; as such no cumulative effect adjustment was recorded. The majority of the Company’s revenues are from interest income and other sources, including loans and investment securities, as well as fees related to mortgage servicing activities, that are not within the scope of ASC 606 and are instead subject to other accounting guidance. The Company’s services that are within the scope of ASC 606 are recorded within non-interest income which includes investment management and advisory fees, service charges on deposit accounts, interchange income and other service charges and fees. Descriptions of these activities that are within the scope of ASC 606, which are presented in the condensed consolidated statements of income as components of non-interest income, are as follows: Service charges on deposit accounts: The Bank earns fees from its deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Bank fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Bank satisfies the performance obligations. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposit accounts are withdrawn from the customer’s account balance. Investment management and advisory fees: The Bank enters into contracts with certain customers to provide asset management services that will continue indefinitely unless terminated in writing by either party to the contract. The Bank receives a quarterly management fee, payable in advance, based on the customer’s assets held under management at the beginning of the period. These fees are earned over time as the Bank provides the contracted services and are assessed based on a tiered rate applied to the market value of assets held under management. The Bank does not earn performance-based incentives. Interchange fees: The Bank earns interchange fees from debit cardholder transactions conducted through the MasterCard payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Such interchange activity is shown on a net basis through other non-interest income. Other service charges and fees: Other charges and fees includes revenue generated from wire transfers, lockboxes, and bank issuance of checks. Such fees are recognized at the point in time the customer requests the service and the service has been rendered. The following table presents the Company’s sources of non-interest income for the three and six months ended June 30, 2018 and 2017 that are within the scope of ASC 606: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Non-Interest Income: Service charges on deposit accounts* $ 52 $ 15 $ 104 $ 55 Investment management and advisory fees 500 589 1,123 1,141 Interchange fees* 27 55 52 81 Other service charges and fees* 13 9 20 12 Not within the scope of ASC 606 5,705 862 10,491 5,467 Total non-interest income $ 6,297 $ 1,530 $ 11,790 $ 6,756 * Included in service charges and fees, and other income in the condensed consolidated statements of income Contract Balances The Bank’s noninterest revenue streams are largely based on transactional activity or month-end revenue accruals such as investment management and advisory fees based on the customer’s assets held under management at the beginning of the period. Consideration is often received immediately or shortly thereafter, and the Bank satisfies its performance obligation and recognizes revenue over time. At June 30, 2018 and December 31, 2017, the Bank had a contract asset balance of $40 and $91, respectively, which was recorded in other assets in the condensed consolidated balance sheets.
Stock-based compensation	Stock-based compensation Compensation cost is recognized for stock options and restricted stock awards issued to employees and non-employee members of the Company’s Board of Directors, based on the fair value of these awards at the date of grant. The fair value of stock options is estimated using a Black-Scholes option pricing model and the fair value of restricted stock awards is based on the market price of the Company’s common stock at the date of grant reduced by the present value of dividends per share expected to be paid during the period the shares are not vested. Compensation cost is recorded over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recorded on a straight-line basis over the requisite service period of the entire award. The Company’s accounting policy is to record forfeitures in the period that they occur.
Income per Share, Basic and Diluted	Income per Share, Basic and Diluted Basic income per share represents net income divided by the weighted average number of common shares outstanding during the period. Diluted income per share represents net income divided by the weighted average number of common shares outstanding during the period, plus the effect of outstanding dilutive potential common shares.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which is intended to improve financial reporting by requiring recording of credit losses on loans and other financial instruments on a more timely basis. The guidance will replace the current incurred loss accounting model with an expected loss approach and requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The guidance requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. ASU No. 2016‑13 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2019. The Company has formed a cross-functional implementation team consisting of individuals from credit, finance and information systems. A project plan has been developed and the implementation team is working on identifying and researching key interpretive issues and is in the process of reviewing existing credit models to identify areas where new impairment models may be required. The Company expects to recognize a cumulative effect adjustment to opening balance of retained earnings as of the beginning of the first reporting period in which ASU No. 2016‑13 is effective. The Company has not yet determined the magnitude of any such one‑time adjustment or the overall impact of ASU No. 2016‑13 on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016‑02, Leases (Topic 842) which require lessees to recognize the following for all leases, except for short‑term leases, at the commencement date: (1) a lease liability which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right‑of‑use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting is largely unchanged. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which provides corrections or clarification on narrow aspects of Topic 842. In July 2018, the FASB also issued ASU 2018-11, Leases (Topic 842): Targeted Improvements , which provides entities with another transition method for adopting the new leasing guidance. As originally issued, ASC 842 requires entities to use a modified restrospective transition approach to apply the new guidance as of the beginning of the earliest period presented in the financial statements in the period adopted. The optional transition method allows entities to apply the new guidance at the adoption date by recognizing a cumulative-effect adjustment to the opening balance of retained earnings, and not to restate the comparative periods presented. ASU No. 2016‑02 will also require expanded disclosures. ASU No. 2016‑02 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018. The Company is currently evaluating the impact of the ASU No. 2016‑02 on its financial condition and results of operations.
