Nature of Operations and Basis of Presentation
Nature of Operations and Basis of Presentation	Note 1—Nature of Operations and Basis of Presentation Nature of Operations Sterling Bancorp, Inc. (the “Company”) is a unitary thrift holding company that was incorporated in 1989 and the parent company to its wholly owned subsidiary, Sterling Bank and Trust, F.S.B. (the “Bank”). The Company’s business is conducted through the Bank which was formed in 1984. The Bank originates construction, residential and commercial real estate loans, commercial lines of credit, and other consumer loans and provides deposit products, consisting primarily of checking, savings and term certificate accounts. The Bank operates through a network of 30 branches of which 26 branches are located in San Francisco and Los Angeles, California with the remaining branches located in New York, New York, Southfield, Michigan and the greater Seattle market. 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. Basis of Presentation The condensed consolidated balance sheet as of March 31, 2019, and the condensed consolidated statements of income, comprehensive income, changes in shareholders’ equity and cash flows for the three months ended March 31, 2019 and 2018 are unaudited. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect all adjustments, in the opinion of management, of a normal recurring nature that are 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 months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ended December 31, 2019 or for any future annual or interim period. The consolidated balance sheet at December 31, 2018 included herein was derived from the audited financial statements as of that date. The accompanying unaudited 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, 2018. Adjustments to Prior Interim Period 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 $544 for the three months ended March 31, 2018. 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 the correction on its previously filed financial statements from a quantitative and qualitative perspective, and has concluded that the correction was not material to the prior period.

New Accounting Standards	3 Months Ended
New Accounting Standards	Mar. 31, 2019
New Accounting Standards
New Accounting Standards	Note 2—New Accounting Standards Adoption of New Accounting Standard The Company has adopted Accounting Standards Update No. 2016-02, Leases (Topic 842) and all subsequent amendments as of January 1, 2019. Topic 842 requires a lessee to recognize the following for all leases, except 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. Topic 842 also requires expanded disclosures. Topic 842 permits entities to use a modified retrospective transition approach to apply the guidance as of the beginning of the earliest period presented in the financial statements in the period adopted or the optional transition method which allows entities to apply the new guidance at the adoption date and record a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, and not to restate the comparative periods presented. The Company adopted Topic 842 as of January 1, 2019 using the optional transition method. Therefore, the comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods. The adoption of the standard resulted in the recognition of operating lease right-of-use assets of $21.8 million and operating lease liabilities of $22.7 million on the condensed consolidated balance sheet as of January 1, 2019. The operating lease right-of-use assets includes the impact of unamortized lease incentives and deferred rent. The Company elected to apply the package of practical expedients upon transition, which includes no reassessment of whether existing contracts are or contain leases and allowed for the lease classification for existing leases to be retained. The Company did not elect the practical expedient to use hindsight, and accordingly the initial lease term did not differ under the new standard versus prior accounting practice. After transition, in certain instances, the cost of renewal options will be recognized earlier in the term of the lease than under the previous lease accounting rules. The Company elected the practical expedient to not separate non-lease components from the lease components contained in the operating lease agreements but instead to combine them and account for them as a single lease component and will continue to do so for its real estate operating leases. The new standard did not have a significant impact on the condensed consolidated statement of income or statement of cash flows for the three months ended March 31, 2019. The Company’s operating leases are included in operating lease right-of-use assets and operating lease liabilities in the condensed consolidated balance sheet at March 31, 2019. The lessors’ rate implicit in the operating leases were not available to the Company and were not determinable from the terms of the leases. Therefore, the Company’s incremental borrowing rate was used in determining the present value of the future lease payments. The incremental borrowing rates were not observable and therefore, the rates were estimated primarily using observable borrowing rates on the Company’s FHLB advances. The FHLB borrowing rates are generally for over collateralized advances for varying lengths of maturity. Therefore, the risk-free U.S. Government bond rate and high-credit quality unsecured corporate bond rates were also considered in estimating the incremental borrowing rates. The Company’s incremental borrowing rates were developed considering its monthly payment amounts and the initial terms of its leases. These incremental borrowing rates were applied to future lease payments in determining the present value of the operating lease liability for each lease. As stated, the comparative prior period information for the three months ended March 31, 2018 has not been adjusted and continues to be reported under the Company’s historical lease recognition policies under ASC Topic 840, Leases. The disclosure requirements of Topic 842 are included within Note 16, Operating Leases. Recently Issued Accounting Guidance Not Yet Adopted In August 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for fair value measurements as follows: (1) removes the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and the reporting entity’s policy for timing of transfers between levels; (2) removes the requirement to disclose the valuation processes for Level 3 fair value measurements; (3) clarifies that the measurement uncertainty disclosure for recurring Level 3 fair value measurements is to communicate information about the uncertainty in measurement as of the reporting date; (4) requires disclosure of the changes in unrealized gains and losses for the period included in other comprehensive income (loss) for recurring Level 3 fair value measurements held at the end of the reporting period; and (5) requires disclosure of the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. ASU No. 2018-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. An entity is permitted to early adopt the provisions that remove or modify disclosures upon issuance of this ASU and delay adoption of the additional disclosures until the effective date. The Company is currently evaluating the impact adoption will have on its current fair value measurement disclosures. In June 2016, 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 and timeline has been developed and the implementation team has been meeting weekly to assess the project status to ensure adherence to the timeline. The implementation team has been working with a software vendor to assist in implementing required changes to credit loss estimation models and processes, and is finalizing the historical data collected to be used in the credit loss models. The Company expects to recognize a cumulative effect adjustment to the 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 condensed consolidated financial statements.

Summary of Significant Accounting Policies	Mar. 31, 2019
Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 3—Summary of Significant Accounting Policies Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared using U.S. GAAP. The condensed consolidated financial statements include the results of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidation. Use of Estimates The preparation of the condensed 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Due to the inherent uncertainty involved in making estimates, actual results reported in the future periods may be based upon amounts that could differ from those estimates. Concentration of Credit Risk The loan portfolio consists primarily of residential real estate loans which are collateralized by real estate. At March 31, 2019 and December 31, 2018, residential real estate loans accounted for 85% and 84%, 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. Approximately 92% and 94% of the loan portfolio was originated in California at March 31, 2019 and December 31, 2018, respectively.

The amortized cost and fair value of debt securities available for sale issued by U.S. Treasury at March 31, 2019 are shown by contractual maturity. Collateralized mortgage obligations 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.

The table summarizes debt securities available for sale, at fair value, with unrealized losses at March 31, 2019 and December 31, 2018 aggregated by major security type and length of time the individual securities have been in a continuous unrealized loss position, as follows:

As of March 31, 2019, the Company’s debt securities portfolio consisted of 8 debt securities, with 3 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.

A collateralized debt obligation with a carrying value of $290 and $297 at March 31, 2019 and December 31, 2018, respectively, 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 underlying collateral for the security are primarily banks. Management 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 collateralized debt obligation remained classified as available for sale and represented $17 and $11 of the unrealized losses reported at March 31, 2019 and December 31, 2018, 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 March 31, 2019 and December 31, 2018, equity securities totaled $4,190 and $4,141, respectively.

At March 31, 2019 and December 31, 2018, equity securities with readily determinable fair values were $3,944 and $3,895, respectively. The following is a summary of unrealized and realized gains and losses recognized in the condensed consolidated statements of income during the three months ended March 31, 2019 and 2018:

The unpaid principal balance is not reduced for partial charge offs. The recorded investment excludes accrued interest receivable on loans which was not significant.

Also presented in the above table is the average recorded investment of the impaired loans and the related amount of interest recognized during the time within the period that the impaired loans were impaired. 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.

The following tables present the recorded investment in nonaccrual and loans past due over 90 days still on accrual by class of loans as of March 31, 2019 and December 31, 2018:

The Company considers the performance of the loan portfolio and its impact on the allowance for loan losses. 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 March 31, 2019 and December 31, 2018, the balance of outstanding loans identified as troubled debt restructurings was $6,968 and $5,826, respectively. The Company has an allowance for loan losses of $51 and $261 on these loans at March 31, 2019 and December 31, 2018, respectively. There were no loans identified as troubled debt restructurings that subsequently defaulted.

During the three months ended March 31, 2019, the terms of a construction loan was modified by providing for an extension of the maturity dates at the contract’s existing rate of interest, which is lower than the current market rate for new debt with similar risk. The total outstanding recorded investments was $1,046 both before and after modification. The effect of the modification on the allowance for loan losses was not significant. The Bank had commitments to lend an additional $498 to customers whose terms have been modified in troubled debt restructuring as of March 31, 2019. During the three months ended March 31, 2018, the Bank did not modify any loans as a troubled debt restructuring.

The terms of certain other loans have been modified during the three months ended March 31, 2019 and 2018 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 significant 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 March 31, 2019 and December 31, 2018, the risk rating of loans by class of loans was as follows:

During the three months ended March 31, 2019 and 2018, the Bank sold pools of residential real estate mortgages for $49.9 million and $112.2 million, 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 $2.4 million and $3.9 million for the three months ended March 31, 2019 and 2018, respectively. After the sales, the Bank’s only continuing involvement in the transferred assets is to act as servicer of the mortgages.

Servicing fee income, net of amortization of servicing rights and changes in the valuation allowance, was $325 and $477 for the three months ended March 31, 2019 and 2018, respectively, and were included in other non-interest income in the condensed consolidated statements of income.

The fair value of mortgage servicing rights was $12,162 and $11,523 at March 31, 2019 and December 31, 2018, 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 March 31, 2019 was determined using discount rates ranging from 9.5% to 12.0%, prepayment speeds ranging from 6.8% to 33.8%, depending on the stratification of the specific right, and a weighted average default rate of 0.2%. The fair value at December 31, 2018 was determined using discount rates ranging from 9.5% to 12.0%, prepayment speeds ranging from 6.8% to 33.6%, depending on the stratification of the specific right, and a weighted average default rate of 0.2%.

At March 31, 2019 and December 31, 2018, the carrying amount of certain individual groupings exceeded their fair values. See Note 13.

Interest on advances is payable monthly and each advance is payable at its maturity date, and may contain a prepayment penalty if paid before maturity. At March 31, 2019, advances totaling $157.0 million were callable by the FHLB as follows: $67.0 million in September 2021; and $90.0 million in October 2021. At March 31, 2019, the Bank had additional borrowing capacity of $377.1 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 $50.0 million. The average amount outstanding during the three months ended March 31, 2019 and 2018 was $4,133 and $3,673, respectively. The Bank had $51 outstanding under this agreement at March 31, 2019. Borrowings accrue interest based on a variable rate based on the FHLB’s overnight cost of funds rate, which was 2.84% and 2.87% at March 31, 2019 and December 31, 2018, respectively. The agreement has a one-year term and terminates in October 2019.

The FHLB advances and the overdraft line of credit are collateralized by pledged loans totaling $1.1 billion at March 31, 2019.

Other Borrowings

The Company had available credit lines with other banks totaling $70.0 million at March 31, 2019 and December 31, 2018. There were no borrowings under these credit lines during the three months ended March 31, 2019 and year ended December 31, 2018.

Stock Repurchase Program	Note 10—Stock Repurchase Program In late 2018, the board of directors approved the repurchase of up to $50.0 million of the Company’s outstanding shares of common stock. The stock repurchase program permits the Company to purchase shares of its common stock from time to time in the open market or in privately negotiated transactions. The Company received regulatory approval of its stock repurchase program and publicly announced the program in January 2019. Under this program, the Company is not obligated to repurchase shares of its common stock. The repurchased shares will be canceled and returned to authorized but unissued status. During the three months ended March 31, 2019, the Company repurchased and cancelled 1,212,574 shares of its common stock for $11,544 including commissions and fees, average repurchase price of $9.52 per share). Such repurchases of common stock were funded through cash on hand.

Stock-based Compensation

Stock-based Compensation

Stock-based Compensation

Note 11—Stock-based Compensation

The board of directors established a 2017 Omnibus Equity Incentive Plan (the “Plan”) which was approved by the shareholders. 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 1, 2019, the board of directors approved the issuance of options to purchase 84,889 shares of common stock with an exercise price of $10.12 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 $3.20 per option. The grant-date fair value of each stock option award for the three months ended March 31, 2019 is estimated using the Black-Scholes option pricing model that uses the assumptions set forth in the following table:


Exercise price of options	$	10.12
Risk-free interest rate		2.66	%
Expected term (in years)		6.75
Expected stock price volatility		26.26	%
Dividend yield		.40	%

A summary of the Company’s stock option activity as of and for the three months ended March 31, 2019 is as follows:


				Weighted

		Average		Remaining	Aggregate
	Number	Exercise		Contractual	Intrinsic

The Company recorded share-based compensation expense associated with stock options of $32 and $3 for the three months ended March 31, 2019 and 2018, respectively. At March 31, 2019, there was $580 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 3.41 years. No options are exercisable at March 31, 2019.

Restricted Stock Awards

On March 1, 2019, the board of directors approved the issuance of 71,144 restricted stock awards to certain key employees. The restricted stock awards vest in installments of 50% in each of the third and fourth year after the date of grant. Upon a change in control, as defined in the Plan, the outstanding restricted stock awards will immediately vest. 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.

A summary of the Company’s restricted stock awards activity for the three months ended March 31, 2019 is as follows:


		Weighted Average
	Number	Grant Date Fair
	of Shares	Value

Nonvested at January 1, 2019	48,975	$	13.55
Granted	71,144		9.97
Vested	(6,555)		13.69
Forfeited	—		—
Nonvested at March 31, 2019	113,564	$	11.30

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 $94 and $6 for the three months ended March 31, 2019 and 2018, respectively. At March 31, 2019, there was $1,065 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 3.50 years.

Note 12—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:

Fair Values of Financial Instruments

Fair Values of Financial Instruments

Note 13—Fair Values of Financial Instruments

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 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 following methods and significant assumptions are used to estimate fair value:

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 analysis. 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, such as comparable sales or income approach, or a combination of both. 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.

Appraisals for collateral-dependent impaired loans are performed by certified general appraisers whose qualifications and licenses have been reviewed and verified by us. Once received, an appraisal compliance review is completed in accordance with regulatory guidelines.

Mortgage Servicing Rights

Fair value of mortgage servicing rights is initially determined at the individual grouping level based on an internal valuation model that calculates the present value of estimated future net servicing income. On a quarterly basis, mortgage servicing rights are evaluated for impairment based upon third party valuations obtained. As disclosed in Note 5, the valuation model utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income (Level 3).

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 March 31, 2019 and December 31, 2018:

Unrealized losses on Level 3 investments for collateralized debt obligations was $17 at March 31, 2019. In addition to the amounts included in income for the three months ended March 31, 2019 as presented in the table above, interest income recorded on collateralized debt obligations was $4. Unrealized losses on Level 3 investments for collateralized debt obligations were $11 at December 31, 2018. In addition to the amounts included in income for the year ended December 31, 2018 as presented in the table above, interest income recorded on collateralized debt obligations was $16.

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 analysis. 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 March 31, 2019 and December 31, 2018:


			Valuation
	Fair Value		Technique	Unobservable Inputs
March 31, 2019
Collateralized debt obligations	$	290	Discounted cash flow	Collateral default rate	0	%
				Recovery probability	0	%
December 31, 2018
Collateralized debt obligations	$	297	Discounted cash flow	Collateral default rate	0	%
				Recovery probability	0	%

The significant unobservable inputs used on the fair value measurement of the 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 March 31, 2019 and December 31, 2018, the following table provides the level of valuation assumptions used to determine each adjustment and the related carrying value:

Regulatory Capital Requirements

Regulatory Capital Requirements

Note 14—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 could 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 condensed consolidated financial statements.

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.

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 was 2.50% starting January 1, 2019. The net unrealized gain or loss on investment securities is not included in regulatory capital. Management believes that at March 31, 2019, the Company and the Bank meet all regulatory capital requirements to which they are subject.

At March 31, 2019, 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 March 31, 2019 and December 31, 2018, 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 minimum not including the capital conservation buffer, at March 31, 2019 and December 31, 2018 are as follows:

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 March 31, 2019, $171.8 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.

- Definition

The entire disclosure for banks, savings institutions, and credit unions, for regulatory capital requirements imposed by the Federal Reserve System (FRB), the Federal Deposit Insurance Corporation (FDIC), the Office of Thrift Supervision (OTS) or for any state imposed capital requirements, as applicable. The disclosure may include (1) a description of regulatory capital requirements (a) for capital adequacy purposes and (b) established by the prompt corrective action provisions of Section 38 of the Federal Depository Insurance Act; (2) the actual or possible material effects of noncompliance with such requirements; (3) whether the entity is in compliance with the regulatory capital requirements including (a) required and actual ratios and amounts of Tier 1 leverage, Tier 1 risk-based, and total risk-based capital, tangible capital (for savings institutions), and Tier 3 capital for market risk (for certain banks and bank holding companies), (b) factors that may significantly affect capital adequacy; (4) the prompt corrective action category in which the entity was classified as of its most recent notification; (5) whether management believes any conditions or events since notification have changed the entity's category. Also may include additional information that might be disclosed in situations where substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time.

Operating Leases

Note 16—Operating Leases

The Company leases its corporate headquarters and branch offices through noncancelable operating lease contracts. Such noncancelable operating lease contracts convey the right to control such real estate for a period of time in exchange for consideration. The operating leases have remaining terms ranging from 2019 to 2029, and generally have options to extend for one or two five-year periods. Beginning in 2019, the lease term may include options to extend the lease when it is reasonably certain that the option will be exercised based on the facts and circumstances at lease commencement. The lease agreements, most often, provide for rental payments that increase over the lease term based on a fixed percentage or based on a specified consumer price index. Any changes in the consumer price index after the lease commencement date are considered variable lease payments and recorded in the period when incurred. Additionally, the Company, in most cases, is required to pay insurance costs, real estate taxes and other operating expenses such as common area maintenance.

The Company leases certain storage and office space from entities owned by the Company’s principal shareholders. Amounts paid under such leases totaled $13 and $17 during the three months ended March 31, 2019 and 2018, respectively. The Company also subleases certain office space to entities owned by the Company’s principal shareholders. Amounts received under such subleases totaled $68 during the three months ended March 31, 2019 and 2018.

Lease expense was $921 for the three months ended March 31, 2018. The components of lease expense, which are recorded in noninterest expense - occupancy and equipment, in the condensed consolidated statements of income for the three months ended March 31, 2019 were as follows:


Operating lease cost	$	1,126

Commitments and Contingencies

Note 17—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.

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 condensed 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 March 31, 2019, outstanding commitments to make loans consisted of fixed rate loans of $11,842 with interest rates ranging from 3.25% to 5.375% and maturities ranging from 10 years to 30 years and variable rate loans of $247,001 with varying interest rates (ranging from 4.00% to 7.875% at March 31, 2019) and maturities ranging from 1.5 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 March 31, 2019 and December 31, 2018:


	March 31,		December 31,
	2019		2018
Commitments to make loans	$	258,843	$	241,809

Summary of Significant Accounting Policies
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared using U.S. GAAP. The condensed consolidated financial statements include the results of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidation.
Use of Estimates	Use of Estimates The preparation of the condensed 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Due to the inherent uncertainty involved in making estimates, actual results reported in the future periods may be based upon amounts that could differ from those estimates.
Concentration of Credit Risk	Concentration of Credit Risk The loan portfolio consists primarily of residential real estate loans which are collateralized by real estate. At March 31, 2019 and December 31, 2018, residential real estate loans accounted for 85% and 84%, 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. Approximately 92% and 94% of the loan portfolio was originated in California at March 31, 2019 and December 31, 2018, respectively.
