Safe Harbor Statement under the Private Securities Litigation Reform Act of 1995

This Quarterly Report on Form 10-Q may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. You can find many (but not all) of these statements by looking for words such as “approximates,” “believes,” “expects,” “anticipates,” “estimates,” “intends,” “plans,” “would,” “may” and other similar expressions in this Quarterly Report on Form 10-Q. With respect to any such forward-looking statements, the Company claims the protection of the safe harbor provided for in the Private Securities Litigation Reform Act of 1995, as amended. The Company cautions investors that any forward-looking statements presented in this Quarterly Report on Form 10-Q, or those that the Company may make orally or in writing from time to time, are based on the beliefs of, assumptions made by, and information available to, management at the time such statements are first made. Actual outcomes will be affected by known and unknown risks, trends, uncertainties and factors that are beyond the Company’s control or ability to predict.  Although the Company believes that management’s beliefs and assumptions are reasonable, they are not guarantees of future performance and some will inevitably prove to be incorrect. As a result, the Company’s actual future results can be expected to differ from management’s expectations, and those differences may be material and adverse to the Company’s business, results of operations and financial condition. Accordingly, investors should use caution in placing any reliance on forward-looking statements to anticipate future results or trends.

Some of the risks and uncertainties that may cause the Company’s actual results, performance or achievements to differ materially from those expressed include, but are not limited to, the following: the risk that the impact of changes in interest rates; political instability; changes in the monetary policies of the U.S. Government; a decline in economic conditions; deterioration in the value of West Coast real estate, both residential and commercial; an increase in the level of non-performing assets and charge-offs; further increased competition among financial institutions; the Company’s ability to continue to attract deposits and quality loan customers; further government regulation, including regulations regarding capital requirements, and the implementation and costs associated with the same; internal and external fraud and cyber-security threats including the loss of bank or customer funds, loss of system functionality or the theft or loss of data; management’s ability to successfully manage the Company’s operations; and the other risks set forth in the Company’s reports filed with the U.S. Securities and Exchange Commission. For further discussion of these and other factors, see “Item 1A. Risk Factors” in Part II of this Quarterly Report on Form 10-Q and the Company’s 2018 Annual Report on Form 10-K.

Any forward-looking statements in this Quarterly Report on Form 10-Q and all subsequent written and oral forward-looking statements attributable to the Company or any person acting on behalf of the Company are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. The Company does not undertake any obligation to release publicly any revisions to forward-looking statements to reflect events or circumstances after the date such forward-looking statements are made, and hereby specifically disclaims any intention to do so, unless required by law.

LUTHER BURBANK CORPORATION

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS

Organization

Luther Burbank Corporation (the ‘‘Company’’), a California corporation headquartered in Santa Rosa, is the bank holding company for its wholly-owned subsidiary, Luther Burbank Savings (the "Bank"), and its wholly-owned subsidiary, Burbank Investor Services. The Company also owns Burbank Financial Inc., a real estate investment company, and all the common interests in Luther Burbank Statutory Trusts I and II, entities created to issue trust preferred securities.

The Bank conducts its business from its headquarters in Manhattan Beach, California. It has nine full service branches in California located in Sonoma, Marin, Santa Clara, and Los Angeles Counties and one full service branch in Washington located in King County. Additionally, there are seven loan production offices located throughout California, as well as a loan production office in Clackamas County, Oregon.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all footnotes as would be necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). However, these interim unaudited consolidated financial statements reflect all adjustments (consisting solely of normal recurring adjustments and accruals) which, in the opinion of management, are necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows for the interim periods presented. These unaudited consolidated financial statements have been prepared on a basis consistent with, and should be read in conjunction with, the audited consolidated financial statements as of and for the year ended December 31, 2018, and the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC, under the Securities and Exchange Act of 1934, (the “Exchange Act”). The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated.

The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results of operations that may be expected for any other interim period or for the year ending December 31, 2019.

The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry.

Use of Estimates

Management is required 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 unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the unaudited consolidated financial statements and the disclosures provided, and actual results could differ.

Earnings Per Share ("EPS")

Basic earnings per common share represents the amount of earnings for the period available to each share of common stock outstanding during the reporting period. Basic EPS is computed based upon net income divided by the weighted average number of common shares outstanding during the year. In determining the weighted average number of shares outstanding, vested restricted stock units are included. Diluted EPS represents the amount of earnings for the period available to each share of common stock outstanding

8

including common stock that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares outstanding during each reporting period. Diluted EPS is computed based upon net income divided by the weighted average number of common shares outstanding during each period, adjusted for the effect of dilutive potential common shares, such as restricted stock awards and units, calculated using the treasury stock method.

New Financial Accounting Standards

FASB ASU 2016-01

In January 2016, the FASB issued ASU 2016-01 which provided guidance to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. This update contains several provisions, including but not limited to (1) requiring equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; (2) simplifying the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (3) eliminating the requirement to disclose the method(s) and significant assumptions used to estimate fair value; and (4) requiring separate presentation of financial assets and liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements. The update also changes certain financial statement disclosure requirements, including requiring disclosures of the fair value of financial instruments be made on the basis of exit price. The update was effective for public business entities ("PBEs") for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. As an emerging growth company, the Company was permitted to adopt this guidance on January 1, 2019 and, as a result, reclassified $399 thousand of unrealized losses on equity securities from other comprehensive income to retained earnings. Subsequent changes in the unrealized gain or loss on equity securities will be recorded through other noninterest income. Additionally, $11.4 million of equity securities were reclassified from available for sale securities to equity securities.

At December 31, 2018, the Company held 82 residential MBS and CMOs of which 45 were in a loss position and 40 had been in a loss position for twelve months or more. The Company held 34 commercial MBS and CMOs of which 23 were in a loss position and 16 had been in a loss position for twelve months or more. The Company held 14 agency bonds of which 13 were in a loss position and 12 had been in a loss position for twelve months or more. The Company held 1 U.S. Treasury note at December 31, 2018. This note was in a loss position for greater than 12 months.

The unrealized losses on the Company’s investments were caused by interest rate changes. In addition, the contractual cash flows of these investments are guaranteed by the U.S. government or agencies sponsored by the U.S. government. Accordingly, it is expected that the securities will not be settled at a price less than amortized cost. Because the decline in market value is attributable to changes in interest rates but not credit quality, and because the Company has the ability and intent to hold those investments until a recovery of fair value, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired at March 31, 2019 and December 31, 2018.

As of March 31, 2019 and December 31, 2018, there were no holdings of securities of any one issuer in an amount greater than 10% of stockholders' equity, other than the U.S. government and its agencies.

At March 31, 2019, the Company had 7 held to maturity residential MBS of which 4 were in a loss position and 4 had been in a loss position for twelve months or more. At December 31, 2018, the Company held 7 held to maturity residential MBS of which 6 were in a loss position and 3 had been in a loss position for twelve months or more.

The unrecognized losses on the Company’s held to maturity investments were caused by interest rate changes. In addition, the contractual cash flows of these investments are guaranteed by agencies sponsored by the U.S. government. Accordingly, it is expected that the securities will not be settled at a price less than amortized cost. Because the decline in market value is attributable to changes in interest rates but not credit quality, and because the Company has the ability and intent to hold those investments until maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2019 and December 31, 2018.

The Company assigns a risk rating to all loans and periodically performs detailed reviews of all such loans to identify credit risks and to assess the overall collectability of the portfolio. During these internal reviews, management monitors and analyzes the financial condition of borrowers and guarantors, as well as the financial performance and other characteristics of loan collateral. These credit quality indicators are used to assign a risk rating to each individual loan. The risk ratings can be grouped into six major categories, defined as follows:

Pass assets are those which are performing according to contract and have no existing or known weaknesses deserving of management’s close attention. The basic underwriting criteria used to approve the loans are still valid, and all payments have essentially been made as planned.

Watch assets are expected to have an event occurring in the next 90 to 120 days that will lead to a change in risk rating with the change being either favorable or unfavorable. These assets require heightened monitoring of the event by management.

Special mention assets have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special mention assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

Substandard assets are inadequately protected by the current net worth and/or paying capacity of the obligor or by the collateral pledged. These assets have well-defined weaknesses: the primary source of repayment is gone or severely impaired (i.e., bankruptcy or loss of employment) and/or there has been a deterioration in collateral value. In addition, there is the distinct possibility that the Company will sustain some loss, either directly or indirectly (i.e., the cost of monitoring), if the deficiencies are not corrected. A deterioration in collateral value alone does not mandate that an asset be adversely classified if such

14

factor does not indicate that the primary source of repayment is in jeopardy.

Doubtful assets have the weaknesses of those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable based on current facts, conditions and values.

Loss assets are considered uncollectible and of such little value that their continuance as assets, without establishment of a specific valuation allowance or charge-off, is not warranted. This classification does not necessarily mean that an asset has absolutely no recovery or salvage value; but rather, it is not practical or desirable to defer writing off a basically worthless asset (or portion thereof) even though partial recovery may be affected in the future.

(Dollars in thousands)	March 31, 2019		December 31, 2018
Troubled debt restructurings:
Single family residential	$	3,512	$	4,410

The Company has allocated $25 thousand of allowances for loans modified in troubled debt restructurings at both March 31, 2019 and December 31, 2018. The Company does not have commitments to lend additional funds to borrowers with loans whose terms have been modified in troubled debt restructurings. There were no new troubled debt restructurings during the three months endedMarch 31, 2019 and 2018.

16

The Company had no troubled debt restructurings with a subsequent payment default within twelve months following the modification during the three months endedMarch 31, 2019 and 2018. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.

4. NONPERFORMING ASSETS

Nonperforming assets include nonperforming loans plus real estate owned. The Company’s nonperforming assets at March 31, 2019 and December 31, 2018 are indicated below:

(Dollars in thousands)	March 31, 2019		December 31, 2018
Non-accrual loans:
Multifamily residential	$	557	$	566
Single family residential	949		1,598
Total non-accrual loans	1,506		2,164
Real estate owned	—		—
Total nonperforming assets	$	1,506	$	2,164

Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of a non-accrual loan is deemed to be fully collectible. If there’s doubt regarding the collectability of the loan, then any interest payments received are applied to principal. Interest income was recognized on a cash basis on two non-accrual loans during the three months ended March 31, 2019 totaling $3 thousand. No interest income was recognized on non-accrual loans during the three months ended March 31, 2018. Contractual interest not accrued on nonperforming loans during the three months ended March 31, 2019 and 2018 totaled $22 thousand and $90 thousand, respectively.

Generally, nonperforming loans are considered impaired, because the repayment of the loan will not be made in accordance with the original contractual agreement.

5. MORTGAGE SERVICING RIGHTS

Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts, disbursing payments to investors, and conducting foreclosure proceedings. Loan servicing income is recorded on the accrual basis and includes servicing fees from investors and certain charges collected from borrowers. Mortgage loans serviced for others are not reported as assets. The principal balances of these loans are as follows:

(Dollars in thousands)	March 31, 2019		December 31, 2018
Mortgage loans serviced for:
Federal Home Loan Mortgage Corporation ("Freddie Mac")	$	490,744	$	497,950

Included in the table above are $33.4 million of single family loans that were sold during the quarter ended March 31, 2019.  In connection with the sale, the Company agreed to service this portfolio for a temporary period of 30 days.  Following this period, the Company will release the servicing rights to the purchaser of this portfolio.

Custodial account balances maintained in connection with serviced loans totaled $948 thousand and $10.1 million at March 31, 2019 and December 31, 2018, respectively.

The Bank has access to the Loan and Discount Window of the Federal Reserve Bank of San Francisco ("FRB"). Advances under this window are subject to the Bank providing qualifying collateral. Various mortgage loans totaling approximately $423.1 million and $406.6 million as of March 31, 2019 and December 31, 2018, respectively, secure this borrowing arrangement. There were no borrowings outstanding with the FRB as of March 31, 2019 and December 31, 2018.

The following table discloses the Bank’s outstanding advances from the FHLB of San Francisco:

	Outstanding Balances				As of March 31, 2019

8. JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES

The Company formed two wholly-owned trust companies (the ‘‘Trusts’’) which issued guaranteed preferred beneficial interests (the "Trust Securities") in the Company’s junior subordinated deferrable interest debentures (the "Notes"). The Company is not considered the primary beneficiary of the Trusts and therefore, the Trusts are not consolidated in the Company’s financial statements, but rather the junior subordinated debentures are shown as a liability. The Company’s investment in the common securities of the Trusts, totaling $1.9 million, is included in other assets on the unaudited consolidated statements of financial condition. The sole asset of the Trusts are the Notes that they hold.

The Trusts have invested the proceeds of such Trust Securities in the Notes. Each of the Notes has an interest rate equal to the corresponding Trust Securities distribution rate. The Company has the right to defer payment of interest on the Notes at any time or from time to time for a period not exceeding five years provided that no extension period may extend beyond the stated maturity of the relevant Notes. During any such extension period, distributions on the Trust Securities will also be deferred, and the Company’s ability to pay dividends on its common stock will be restricted.

19

The Company has entered into contractual arrangements which, taken collectively, fully and unconditionally guarantee payment of: (i) accrued and unpaid distributions required to be paid on the Trust Securities; (ii) the redemption price with respect to any Trust Securities called for redemption by the Trusts; and (iii) payments due upon a voluntary or involuntary dissolution, winding up or liquidation of the Trusts. The Trust Securities are mandatorily redeemable upon maturity of the Notes, or upon earlier redemption as provided in the indenture. The Company has the right to redeem the Notes purchased by the Trusts, in whole or in part, on or after the redemption date. As specified in the indenture, if the Notes are redeemed prior to maturity, the redemption price will be the principal amount and any accrued but unpaid interest.

The following table is a summary of the outstanding Trust Securities and Notes at March 31, 2019 and December 31, 2018 (dollars in thousands):

	March 31, 2019				December 31, 2018				Date	Maturity	Rate Index
Issuer	Amount		Rate		Amount		Rate		Issued	Date	(Quarterly Reset)
Luther Burbank Statutory Trust I	$	41,238	3.99	%	$	41,238	4.17	%	3/1/2006	6/15/2036	3 month LIBOR + 1.38%

9. SENIOR DEBT

In September 2014, the Company issued $95 million in senior unsecured term notes to qualified institutional investors. The following table summarizes information on these notes as of March 31, 2019 and December 31, 2018:

	March 31, 2019				December 31, 2018

Senior Unsecured Term Notes	$	95,000	$	676	$	95,000	$	707	9/30/2024	6.50	%

10. STOCK BASED COMPENSATION

The Company’s stock based compensation consists of restricted stock awards ("RSAs") and restricted stock units ("RSUs") granted under the Luther Burbank Corporation Omnibus Equity and Incentive Compensation Plan ("Omnibus Plan"). In connection with its initial public offering ("IPO") in December 2017, the Company granted RSAs and RSUs to employees and nonemployee directors which all vest ratably over three years. At the same time, the Company granted RSUs in exchange for unvested phantom stock awards held by employees and all vested and unvested phantom stock awards held by nonemployee directors on a per share basis. The RSUs were subjected to the same vesting schedule and deferral elections that existed for the original phantom stock awards.

Awards granted subsequent to the IPO vest ratably over one year for nonemployee directors and ratably over three to four years for employees.

All RSAs and RSUs were granted at the fair value of the common stock at the time of the award. The RSAs and RSUs are considered fixed awards as the number of shares and fair value are known at the date of grant and the fair value at the grant date is amortized over the vesting and/or service period.

Non-cash stock compensation expense recognized for RSAs and RSUs for the three months ended March 31, 2019 and 2018 totaled $838 thousand and $1.0 million, respectively. The fair value of RSAs and RSUs that vested during the three months ended March 31, 2019 and 2018 totaled $5.7 million and $1.5 million, respectively.

As of March 31, 2019 and December 31, 2018, there was $6.3 million and $4.3 million of unrecognized compensation expense related to 758,182 and 985,869 unvested RSAs and RSUs, respectively. As of March 31, 2019 and December 31, 2018, this expense is expected to be recognized over a weighted average period of 2.12 years and 1.91 years, respectively. As of March 31, 2019 and December 31, 2018, 522,464 and 169,490 shares, respectively, of RSUs were vested and remain unsettled per the original deferral elections.

	Three Months Ended March 31,
	2019				2018
	Number of Shares		Weighted Average Grant Date Fair Value		Number of Shares		Weighted Average Grant Date Fair Value
Beginning of the period balance	1,155,359		$	10.97	1,319,700		$	10.75

End of the period balance	1,280,646		$	10.63	1,396,381		$	10.94

Under its Omnibus Plan, the Company reserved 3,360,000 shares of common stock for new awards. At March 31, 2019 and December 31, 2018, there were 2,287,025 and 2,581,960 shares, respectively, of common stock reserved and available for grant through restricted stock or other awards under the Omnibus Plan.

11. FAIR VALUE MEASUREMENTS

Fair Value Measurements

Fair Value Hierarchy

The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Valuations within these levels are based upon:

Level 1 - Quoted market prices for identical instruments traded in active exchange markets.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable or can be corroborated by observable market data.

Level 3 - Model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use on pricing the asset or liability. Valuation techniques include management judgment and estimation which may be significant.

Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company.

Management monitors the availability of observable market data to assess the appropriate classification of assets and liabilities within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities, or total earnings.

The following methods and assumptions were used to estimate the fair value of financial instruments:

For cash and cash equivalents, accrued interest receivable and payable, demand deposits and short-term borrowings, the carrying amount is estimated to be fair value. The fair value of accrued interest receivable/

21

payable balances are determined using inputs and fair value measurements commensurate with the asset or liability from which the accrued interest is generated.

Fair values for available for sale and held to maturity debt securities, which include primarily debt securities issued by U.S. government sponsored agencies, are based on quoted market prices for similar securities.

Fair values for equity securities, which consist of investments in the CRA Qualified Investment Fund are based on quoted market prices for similar securities.

Loans are valued using the exit price notion. The fair value is estimated using market quotes for similar assets or the present value of future cash flows, discounted using a market rate for similar products and giving consideration to estimated prepayment risk and credit risk. The fair value of loans is determined utilizing estimates resulting in a Level 3 classification.

Impaired loans are measured for impairment based on the present value of expected future cash flows discounted at the loans' effective interest rate, except that as a practical expedient, the Company may measure impairment based on a loan’s observable market price, or the fair value of the collateral (net of estimated costs to sell) if the loan is collateral dependent. The fair value of impaired loans is determined utilizing estimates resulting in a Level 3 classification.

It was not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability.

The fair value of servicing rights is determined using a valuation model that utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against available market data.

The fair values of derivatives are based on valuation models using observable market data as of the measurement date.

Fair values for fixed-rate certificates of deposit are estimated using discounted cash flow analyses using interest rates offered at each reporting date by the Company for certificates with similar remaining maturities. For deposits with no contractual maturity, the fair value is assumed to equal the carrying value.

The fair value of FHLB advances is estimated based on discounting the future cash flows using the market rate currently offered for similar terms.

The fair value of subordinated debentures is based on an indication of value provided by a third-party broker.

For senior debt, the fair value is based on an indication of value provided by a third-party broker.

These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates.

Assets and Liabilities Recorded at Fair Value

The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring and nonrecurring basis as of March 31, 2019 and December 31, 2018.

There were no transfers between Level 1 and Level 2 during the three months endedMarch 31, 2019 and 2018.

Non-recurring Basis

The Company may be required, from time to time, to measure certain assets and liabilities at fair value on a non-recurring basis.

For the three months ended March 31, 2019 and 2018, there were no assets or liabilities measured at fair value on a non-recurring basis. The company held no real estate owned at March 31, 2019 and December 31, 2018.

12. VARIABLE INTEREST ENTITIES ("VIE")

The Company is involved with VIEs through its loan securitization activities. The Company evaluated its association with VIEs for consolidation purposes. Specifically, a VIE is to be consolidated by its primary beneficiary, the entity that has both the power to direct the activities that most significantly impact the VIE and a variable interest that could potentially be significant to the VIE. A variable interest is a contractual, ownership or other interest whose value fluctuates with the changes in the value of the VIE's assets and liabilities. The assessment includes an evaluation of the Company's continuing involvement with the VIE and the nature and significance of its variable interests.

24

Multifamily loan securitization

With respect to the securitization transaction with Freddie Mac which settled September 27, 2017, the Company's variable interests reside with a reimbursement agreement entered into with Freddie Mac that obligates the Bank to reimburse Freddie Mac for any defaulted contractual principal and interest payments identified after the ultimate resolution of the defaulted loans. Such reimbursement obligations are not to exceed 10% of the original principal amount of the loans comprising the securitization pool. As part of the securitization transaction, the Bank released all servicing obligations and rights to Freddie Mac who was designated as the Master Servicer. As Master Servicer, Freddie Mac appointed the Bank with sub-servicing obligations, which include obligations to collect and remit payments of principal and interest, manage payments of taxes and insurance, and otherwise administer the underlying loans. The servicing of defaulted loans and foreclosed loans was assigned to a separate third party entity, independent of the Bank and Freddie Mac. Freddie Mac, in its capacity as Master Servicer, can terminate the Bank in its role as sub-servicer and direct such responsibilities accordingly. In evaluating the variable interests and continuing involvement in the VIE, the Company determined that it does not have the power to make significant decisions or direct the activities that most significantly impact the economic performance of the VIE's assets and liabilities. As sub-servicer of the loans, the Bank does not have the authority to make significant decisions that influence the value of the VIE's net assets and therefore, is not the primary beneficiary of the VIE. Therefore, the Company determined that the VIE associated with the multifamily securitization should not be included in the consolidated financial statements of the Bank.

The Company believes its maximum exposure to loss as a result of involvement with the VIE associated with the securitization under the reimbursement agreement executed with Freddie Mac is 10% of the original principal amount of the loans comprising the securitization pool, or $62.6 million. The reserve for estimated losses with respect to the reimbursement obligation totaled $1.4 million as of both March 31, 2019 and December 31, 2018, respectively, based upon an analysis of quantitative and qualitative data over the underlying loans included in the securitization pool. No disbursements have been made in connection with the reimbursement obligation.

13. LOAN SALE AND SECURITIZATION ACTIVITIES

The Company sells originated and acquired loans as part of its business operations and overall management of liquidity, assets and liabilities, and financial performance. The transfer of loans is executed in securitization or sale transactions. With respect to sale transactions, the Company's continuing involvement may or may not include ongoing servicing responsibilities and general representations and warranties. With respect to securitization sales, the Company executed its first and only transaction on September 27, 2017 with Freddie Mac. The transaction involved the sale of $626 million in originated multifamily loans through a Freddie Mac sponsored transaction. The Company's continuing involvement includes sub-servicing responsibilities, general representations and warranties, and reimbursement obligations.

As sub-servicer for Freddie Mac, the Bank is required to maintain a minimum net worth in accordance with GAAP of not less than $2.0 million. If Luther Burbank Savings’ capital were to fall below this threshold, Freddie Mac would have the authority to terminate and assume the Bank’s sub-servicing duties. At March 31, 2019, the Bank’s net worth was $723.6 million.

General representations and warranties associated with loan sales and securitization sales require the Bank to uphold various assertions that pertain to the underlying loans at the time of the transaction, including, but not limited to, compliance with relevant laws and regulations, absence of fraud, enforcement of liens, no environmental damages, and maintenance of relevant environmental insurance. Such representations and warranties are limited to those that do not meet the quality represented at the transaction date and do not pertain to a decline in value or future payment defaults. In circumstances where the Bank breaches its representations and warranties, the Bank would generally be required to cure such instances through a repurchase or substitution of the subject loan(s).

With respect to the securitization transaction, the Bank also has continuing involvement through a reimbursement agreement executed with Freddie Mac. To the extent the ultimate resolution of defaulted loans results in contractual principal and interest payments that are deficient, the Bank is obligated to reimburse Freddie Mac for such amounts, not to exceed 10% of the original principal amount of the loans comprising the securitization pool at the closing date of September 27, 2017.

Included in the table above are $33.4 million of single family loans that were sold during the quarter ended March 31, 2019.  In connection with the sale, the Company agreed to service this portfolio for a temporary period of approximately 30 days.  Following this period, the Company released the servicing rights to the purchaser of this portfolio.

14. COMMITMENTS AND CONTINGENCIES

Financial Instruments With Off-Balance Sheet Risk

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments represent commitments to originate fixed and variable rate loans and loans in process, and involve, to varying degrees, elements of interest rate risk and credit risk in excess of the amount recognized in the Company’s consolidated statements of financial condition. The Company’s exposure to credit loss in the event of nonperformance by the other party for commitments to extend credit and lines of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments to originate loans as it does for on-balance sheet instruments.

Commitments to fund loans are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have expiration dates or other termination clauses. In addition, external market forces may impact the probability of commitments being exercised; therefore, total commitments outstanding do not necessarily represent future cash requirements.

At March 31, 2019 and December 31, 2018, the Company had outstanding commitments of approximately $89.2 million and $70.9 million, respectively, for loans. Unfunded loan commitment reserves totaled $24 thousand and $52 thousand at March 31, 2019 and December 31, 2018, respectively.

26

Operating Leases

The Company leases various office premises under long-term operating lease agreements. These leases expire between 2019 and 2029, with certain leases containing either three, five or ten year renewal options. At March 31, 2019, minimum commitments under these non-cancellable leases before considering renewal options are (dollars in thousands):

April 1 - December 31, 2019	$	3,965
Year ending December 31, 2020	3,952
Year ending December 31, 2021	3,484
Year ending December 31, 2022	2,526
Year ending December 31, 2023	1,257
Thereafter	1,289
Total	$	16,473

Rent expense under operating leases was $1.3 million for both the three months ended March 31, 2019 and 2018. Sublease income earned was $177 thousand and $201 thousand for the three months ended March 31, 2019 and 2018, respectively.

Contingencies

At present, there are no pending or threatened proceedings against the Company which, if determined adversely, would have a material effect on the Company’s business, financial position, results of operations, cash flows or stock price. In the ordinary course of operations, the Company may be party to various legal proceedings.

Correspondent Banking Agreements

The Company maintains funds on deposit with other federally insured financial institutions under correspondent banking agreements. These balances are insured by the FDIC up to $250 thousand. At March 31, 2019 and December 31, 2018, the Company had $1.1 million and $736 thousand, respectively, in cash balances exceeding the insured amounts.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following is a discussion of our financial condition at March 31, 2019 and December 31, 2018 and our results of operations for the three months ended March 31, 2019 and 2018, and should be read in conjunction with our audited consolidated financial statements set forth in our Annual Report on Form 10-K for the year ended December 31, 2018 that was filed with the Securities and Exchange Commission (the “SEC”) on March 4, 2019 (our “Annual Report”) and with the accompanying unaudited notes to consolidated financial statements set forth in this Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2019 (this “Report”). Because we conduct all of our material business operations through our bank subsidiary, Luther Burbank Savings, the discussion and analysis relates to activities primarily conducted by the Bank.

Overview

We are a bank holding company headquartered in Santa Rosa, California, and the parent company of Luther Burbank Savings, a California-chartered commercial bank headquartered in Manhattan Beach, California with $7.0 billion in assets at March 31, 2019. Our principal business is providing high-value, relationship-based banking products and services to our customers, which include real estate investors, professionals, entrepreneurs, high net worth individuals and commercial businesses. We generate most of our revenue from interest on loans and investments. Our primary source of funding for our loans is retail deposits and we place secondary reliance on wholesale funding, primarily borrowings from the FHLB and brokered deposits. Our largest expenses are interest on deposits and borrowings along with salaries and related employee benefits. Our principal lending products are real estate secured loans, consisting primarily of multifamily residential properties and jumbo single family residential properties on the West Coast.

Management's Discussion and Analysis of Financial Condition and Results of Operations - ‘‘Non-GAAP Financial Measures’’ for a reconciliation of our non-GAAP measures to the most directly comparable GAAP financial measure. Pre-tax, pre-provision net earnings is defined as income before taxes and provision for loan losses. Tangible book value is defined as total assets less goodwill and total liabilities. Efficiency ratio is defined as the ratio of noninterest expense to net interest income plus noninterest income.

Critical Accounting Policies and Estimates

Our unaudited consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States and with general practices within the financial services industry. Application of these principles requires management to make complex and subjective estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under current circumstances. These assumptions form the basis for our judgments about the carrying values of assets and liabilities that are not readily available from independent, objective sources. We evaluate our estimates on an ongoing basis. Use of alternative assumptions may have resulted in significantly different estimates. Actual results may differ from these estimates.

Our most significant accounting policies are described in Note 1 to our audited Financial Statements for the year ended December 31, 2018, included on Form 10-K. We have identified the following accounting policies and estimates that, due to the difficult, subjective or complex judgments and assumptions inherent in those policies and estimates and the potential sensitivity of our financial statements to those judgments and assumptions, are critical to an understanding of our financial condition and results of operations. We believe that the judgments, estimates and assumptions used in the preparation of our financial statements are reasonable and appropriate.

Pursuant to the JOBS Act, as an emerging growth company, we can elect to opt out of the extended transition period for adopting any new or revised accounting standards. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we may adopt the standard for the private company.

29

We have elected to take advantage of the scaled disclosures and other relief under the JOBS Act, and we may take advantage of some or all of the reduced regulatory and reporting requirements that will be available to us under the JOBS Act, so long as we qualify as an emerging growth company.

Allowance for Loan Losses

The allowance for loan losses is provided for probable incurred credit losses inherent in the loan portfolio at the statement of financial condition date. The allowance is increased by a provision charged to expense and reduced by loan principal charge-offs, net of recoveries. Where management determines that the allowance for loan losses is more than adequate to absorb the probable incurred credit losses in the portfolio, the allowance is reduced by recapturing provisions and a credit is made to the expense account. The allowance is based on management’s assessment of various factors including, but not limited to, the nature of the loan portfolio, previous loss experience, known and inherent risks in the portfolio, the estimated value of underlying collateral, information that may affect a borrower’s ability to repay, current economic conditions and the results of our ongoing reviews of the portfolio.

While we use available information, including independent appraisals for collateral, to estimate the extent of probable incurred loan losses within the loan portfolio, inherent uncertainties in the estimation process make it reasonably possible that ultimate losses may vary significantly from our original estimates. Generally, loans are partially or fully charged off when it is determined that the unpaid principal balance exceeds the current fair value of the collateral with no other likely source of repayment.

Fair Value Measurement

We use estimates of fair value in applying various accounting standards for our unaudited consolidated financial statements. Fair value is defined as the exit price at which an asset may be sold or a liability may be transferred in an orderly transaction between willing and able market participants. When available, fair value is measured by looking at observable market prices for identical assets and liabilities in an active market. When these are not available, other inputs are used to model fair value such as prices of similar instruments, yield curves, prepayment speeds and credit spreads. Depending on the availability of observable inputs and prices, different valuation models could produce materially different fair value estimates. The values presented may not represent future fair values and may not be realizable.

Changes in the fair value of debt securities available for sale and derivatives designated as effective cash flow hedges are recorded in our unaudited consolidated statements of financial condition and comprehensive income (loss) while changes in the fair value of equity securities, loans held for sale and other derivatives are recorded in the unaudited consolidated statements of financial condition and in the unaudited consolidated statements of income.

Investment Securities Impairment

We assess on a quarterly basis whether there have been any events or economic circumstances to indicate that a security in which we have an unrealized loss is impaired on an other-than-temporary basis. In any instance, we would consider many factors, including the severity and duration of the impairment, the portion of any unrealized loss attributable to a decline in the credit quality of the issuer, our intent and ability to hold the security for a period of time sufficient for a recovery in value, recent events specific to the issuer or industry, and, for debt securities, external credit ratings and recent downgrades. Securities with respect to which there is an unrealized loss that is deemed to be other-than-temporary are written down to fair value.

Non-GAAP Financial Measures

Some of the financial measures discussed in this Quarterly Report on Form 10-Q are ‘‘non-GAAP financial measures.’’ In accordance with SEC rules, we classify a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles as in effect from time to time in the United States in our unaudited consolidated statements of income, statements of financial condition or statements of cash flows.

30

Pre-tax, pre-provision net earnings is defined as income before taxes and provision for loan losses. We believe the most directly comparable GAAP financial measure is income before taxes. Disclosure of this measure enables you to compare our operations to those of other banking companies before consideration of taxes and provision expense. Efficiency ratio is defined as noninterest expenses divided by operating revenue, which is equal to net interest income plus noninterest income. Tangible book value per share is defined as tangible stockholders' equity divided by period end shares outstanding. We believe that these non-GAAP financial measures provide useful information to management and investors that is supplementary to our statements of financial condition, results of income and cash flows computed in accordance with GAAP. However, we acknowledge that our non-GAAP financial measures have a number of limitations. As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP, and they are not necessarily comparable to non-GAAP financial measures that other banking companies use. Other banking companies may use names similar to those we use for the non-GAAP financial measures we disclose, but may calculate them differently. You should understand how we and other companies each calculate their non-GAAP financial measures when making comparisons.

Results of operations - Three Months Ended March 31, 2019 and 2018

Overview

For the three months ended March 31, 2019, our net income was $12.0 million as compared to $11.1 million for the same period last year. The increase of $908 thousand, or 8.2%, was attributed primarily to an increase of $1.6 million in net interest income and a decrease of $1.2 million in provision for loan losses, partially offset by an increase in noninterest expense of $1.5 million. Pre-tax, pre-provision net earnings increased by $446 thousand, or 2.7%, for the three months ended March 31, 2019 as compared to the same period last year.

Net Interest Income

Net interest income increased by $1.6 million, or 5.3%, to $32.1 million for the three months ended March 31, 2019 from $30.5 million for the same period last year primarily due to growth in the average balance and yield of our loan portfolio. During the quarter ended March 31, 2019, the average balance of loans increased by $1.0 billion and the yield increased by 35 basis points, compared to the same period last year. The improvement in net interest income was further enhanced by growth in the average balance and yield of our investment portfolio, which increased by $113.1 million and 57 basis points, respectively. This increase during the current quarter compared to the same period

31

last year was partially offset by growth in the average balance and costs of our deposits and FHLB advances. The average balance and cost of deposits increased $1.0 billion and 74 basis points, respectively, and the average balance and cost of FHLB advances increased $54.2 million and 64 basis points, respectively, compared to the same period last year. Our net interest margin of 1.86% for the three months ended March 31, 2019 decreased from our net interest margin of 2.11% for the same period last year. The decline in net interest margin from the same period last year primarily relates to our rising cost of funds which has generally outpaced the increases in yields on our interest earning assets.

(1) Non-accrual loans are included in total loan balances. No adjustment has been made for these loans in the calculation of yields. Interest income on loans includes amortization of deferred loan costs, net of deferred loan fees. Net deferred loan cost amortization totaled $2.6 million and $2.3 million for the three months ended March 31, 2019 and 2018, respectively.

(2) Noninterest-earning assets includes the allowance for loan losses.

(3) Net interest spread is the average yield on total interest-earning assets minus the average rate on total interest-bearing liabilities.

(4) Net interest margin is net interest income divided by total interest-earning assets.

Interest rates and operating interest differential. Increases and decreases in interest income and interest expense

32

result from changes in average balances (volume) of interest-earning assets and interest-bearing liabilities, as well as changes in average interest rates. The following table shows the effect that these factors had on the interest earned from our interest-earning assets and interest incurred on our interest-bearing liabilities during the periods indicated. The effect of changes in volume is determined by multiplying the change in volume by the prior period’s average rate. The effect of rate changes is calculated by multiplying the change in average rate by the prior period’s volume. The change in interest due to both rate and volume has been allocated to rate and volume changes in proportion to the relationship of the absolute dollar amounts of the changes in each.

Total interest income increased by $16.1 million, or 32.7%, for the three months ended March 31, 2019 as compared to the same period last year. Interest income from loans accounted for $14.5 million of that amount as the average daily balance of loans increased by $1.0 billion, or 19.4%. The interest income increase from greater average loan balances was further enhanced by a 35 basis point increase in loan yield. The volume of new loans originated totaled $311.5 million and $477.9 million for the three months ended March 31, 2019 and 2018, respectively. The decreased originations compared to the same period last year is due to a slowing in demand for hybrid real estate loans. The weighted average rate on new loans for the three months ended March 31, 2019 was 4.62% as compared to 4.31% for the same period last year. The increasing rate was caused by a general rise in interest rates. Loan prepayment speeds were 13.66% and 11.53% during the three months ended March 31, 2019 and 2018, respectively. The weighted average rate on loan payoffs/curtailments during the three months ended March 31, 2019 was 4.19% as compared to 3.89% for the same period last year.

Total interest expense increased $14.5 million to $33.3 million for the three months ended March 31, 2019 from $18.8 million for the same period last year. Interest expense on deposits increased $12.4 million to $24.3 million for the three months ended March 31, 2019 from $11.9 million for the same period of last year. This increase is due to average daily deposit balances increasing by $1.0 billion, or 25.7%, from period to period, as well as cost of deposits increasing to 1.94% for the three months ended March 31, 2019, from 1.20% for the same period last year. Interest expense on advances from the FHLB increased by $2.0 million due to a 64 basis point increase in the cost of those advances as compared to the same period last year. The increase in the cost of deposits and FHLB advances were caused by deposit competition and rising interest rates. FHLB advances were further impacted by an extension in the duration of the portfolio during the quarter ended March 31, 2019 compared to the same period last year, which increased to

33

a weighted average remaining maturity of 2.3 years at March 31, 2019 compared to 1.2 years at March 31, 2018. We use both deposits and FHLB advances to fund net loan growth. We also use FHLB advances, with or without embedded interest rate caps, as a hedge of interest rate risk, as we can strategically control the duration of those funds. A discussion of instruments used to mitigate interest rate risk can be found under Part I - Financial Information, Item 3. ‘‘Quantitative and Qualitative Disclosures About Market Risk.’’

Provision for Loan Losses

Provision for loan losses totaled $300 thousand for the three months ended March 31, 2019 as compared to $1.5 million for the same period last year. The lower loan loss provisions during the current quarter compared to the same period last year were primarily due to the sustained performance of our loan portfolio, improving credit quality and slower loan growth and corresponding loan originations. Nonperforming loans totaled $1.5 million, or 0.02% of total loans, at March 31, 2019, compared to $2.2 million, or 0.04% of total loans, at December 31, 2018. Our allowance for loan losses as a percentage of total loans was 0.56% at March 31, 2019 as compared to 0.60% and 0.56% at March 31, 2018 and December 31, 2018, respectively.

While loans in our portfolio occasionally become impaired, the loans, as individually analyzed and measured, often do not require a charge-off or reserve for loss. Nonperforming loans as a percentage of total loans decreased from 0.13% to 0.02% from March 31, 2018 to March 31, 2019. By dollar balance, 84% of those loans were current and paying as agreed at March 31, 2019. Our classified loans as a percentage of total loans increased slightly by 3 basis points, from 0.12% to 0.15%, over the same period last year.

Noninterest Income

Noninterest income increased by $355 thousand to $1.4 million for the three months ended March 31, 2019 from $1.0 million for the same period last year.

The following table presents the major components of our noninterest income:

	For the Three Months Ended March 31,
(Dollars in thousands)	2019		2018		$ Increase (Decrease)			% Increase (Decrease)
Noninterest Income
Gain on sale of loans	$	333	$	—	$	333		N/A
FHLB dividends	495		594		(99		)	(16.7	)%
Fee income	285		313		(28		)	(8.9	)%
Other	267		118		149			126.3	%
Total noninterest income	$	1,380	$	1,025	$	355		34.6	%

The increase in noninterest income for the quarter ended March 31, 2019 compared to the quarter ended March 31, 2018, was primarily attributable to the $333 thousand gain on sale of loans during the current quarter. During the quarter ended March 31, 2019, the Bank sold $19.5 million of multifamily residential loans and $33.4 million of single family residential loans.

Noninterest Expense

Noninterest expense increased $1.5 million, or 10.4%, to $16.2 million for the three months ended March 31, 2019 from $14.7 million for the three months ended March 31, 2018.

The following table presents the components of our noninterest expense for the three months ended March 31, 2019 and 2018:

	For the Three Months Ended March 31,
(Dollars in thousands)	2019		2018		$ Increase (Decrease)			% Increase (Decrease)
Noninterest Expense
Compensation and related benefits	$	10,052	$	9,619	$	433		4.5	%
Deposit insurance premium	498		432		66			15.3	%
Professional and regulatory fees	441		398		43			10.8	%
Occupancy	1,390		1,296		94			7.3	%
Depreciation and amortization	665		714		(49		)	(6.9	)%
Data processing	919		788		131			16.6	%
Marketing	1,154		213		941			441.8	%
Other expenses	1,130		1,253		(123		)	(9.8	)%
Total noninterest expense	$	16,249	$	14,713	$	1,536		10.4	%

The increase in noninterest expense during the three months ended March 31, 2019 was primarily attributable to an increase of $941 thousand in marketing expenses related to deposit gathering efforts, as well as an increase of $433 thousand in compensation costs due to a decline in the deferral of loan origination costs caused by slower loan originations during the current quarter as compared the same period last year. Loan growth moderated during the current quarter due to a slowing in demand for hybrid real estate loans.

Income Tax Expense

For the three months ended March 31, 2019, we recorded income tax expense of $4.9 million as compared to $4.2 million for the same period last year with effective tax rates of 29.0% and 27.3%, respectively. The variance in effective rates was due to a non-recurring true-up to our deferred taxes recorded during the three months ended March 31, 2018 related to our 2017 tax returns.

Financial condition - As of March 31, 2019 and December 31, 2018

Total assets at March 31, 2019 were $7.0 billion, an increase of $54.8 million from December 31, 2018. The increase was primarily due to a $30.3 million, or 5.0%, increase in available for sale debt securities, a $13.6 million, or 0.2%, increase in loans held-for-investment and a $12.9 million, or 14.0%, increase in cash and cash equivalents. Absent loan sales of $52.9 million during the three months ended March 31, 2019, loan growth would have been $66.5 million. Total liabilities increased $47.7 million, or 0.7%, to $6.4 billion at March 31, 2019 from December 31, 2018. The increase in total liabilities was primarily attributable to growth in our deposits of $80.8 million, or 1.6%, partially offset by a decrease in FHLB advances of $33.5 million, or 2.9%, compared to December 31, 2018.

Loan Portfolio Composition

Our loan portfolio is our largest class of earning assets and typically provides higher yields than other types of earning assets. Associated with the higher yields is an inherent amount of credit risk which we attempt to mitigate with strong underwriting. As of both March 31, 2019 and December 31, 2018, our total loans amounted to $6.1 billion. The following table presents the balance and associated percentage of each major product type within our portfolio as of the dates indicated.

Total loans	$	6,144,268			$	6,130,630

Over the past few years, we have experienced significant growth in our loan portfolio, although the relative composition of the portfolio has not changed significantly. Our primary focus remains multifamily real estate lending, which constitutes 62% and 60% of our portfolio at March 31, 2019 and December 31, 2018, respectively. Single family residential lending is our secondary lending emphasis and represents 35% and 37% of our portfolio at March 31, 2019 and December 31, 2018, respectively.

We recognize that these two loan products represent concentrations within our balance sheet. Multifamily loan balances as a percentage of risk-based capital were 549.5% and 540.0% as of March 31, 2019 and December 31, 2018, respectively. Our single family loans as a percentage of risk-based capital were 316.6% and 332.8% as of the same dates. Additionally, our loans are geographically concentrated with borrowers and collateral properties on the West Coast. At March 31, 2019, 59%, 27% and 12% of our real estate loans were collateralized by properties in southern California counties, northern California counties and Washington, respectively, compared to 59%, 28% and 12% for southern California counties, northern California counties and Washington, respectively, at December 31, 2018.

Our lending strategy has been to focus on products and markets where we have significant expertise. Given our concentrations, we have established strong risk management practices including risk-based lending standards, self-established product and geographical limits, annual evaluations of income property loans and semi-annual stress testing. We expect to continue growing our loan portfolio. We have placed more recent focus on originating non-residential commercial real estate loans in our core markets and we anticipate further geographic expansion of our single family and multifamily products into strategically selected West Coast markets.

We have a small portfolio of construction loans with commitments (funded and unfunded) totaling $18.3 million and $20.3 million at March 31, 2019 and December 31, 2018, respectively. As a result of the California fires impacting our local communities, and our desire to help rebuild homes in the affected areas, we re-established our construction lending program and we are actively pursuing opportunities to finance residential construction throughout our lending area.

(1) Other changes in loan balances primarily represent the net change in disbursements on unfunded commitments and deferred loan costs and, to the extent applicable, may include foreclosures, charge-offs and negative amortization.

Multifamily residential loans. We provide multifamily residential loans for the purchase or refinance of apartment buildings of five units or more, with the financed properties serving as collateral for the loan. Our multifamily lending is built around three core principles: market selection, deal selection and sponsor selection. We focus on markets with a high barrier to entry for new development, where there is a limited supply of new housing and where there is a high variance between the cost to rent and the cost to own. We typically lend on stabilized and seasoned assets and focus on older, smaller properties with rents at or below market levels, catering to low and middle income renters. Our customers are generally experienced real estate professionals who desire regular income/cash flow streams and are focused on building wealth steadily over time. We have instituted strong lending policies to mitigate credit and concentration risk. At March 31, 2019, our multifamily real estate portfolio had an average loan balance of $1.6 million, an average unit count of 15.6 units, a weighted average loan to value of 57.0% and a weighted average debt service coverage ratio of 1.49, as compared to an average loan balance of $1.6 million, an average unit count of 15.9 units, a weighted average loan to value of 57.1% and a weighted average debt service coverage ratio of 1.53 at December 31, 2018.

Single family residential loans. We provide permanent financing on single family residential properties primarily located in our market areas, which are both owner-occupied and investor owned. We conduct this business primarily through a network of third party mortgage brokers with the intention of retaining these loans in our portfolio. The majority of our originations are for purchase transactions, but we also provide refinancings. Our underwriting criteria focuses on debt ratios, credit scores, liquidity of the borrower and the borrower’s cash reserves. At March 31, 2019, our single family residential real estate portfolio had an average loan balance of $908 thousand, a weighted average loan to value of 64.5% and a weighted average credit score at origination/refreshed of 751. At December 31, 2018, our single family residential real estate portfolio had an average loan balance of $889 thousand, a weighted average loan to value of 65.2% and a weighted average credit score at origination/refreshed of 751.

Commercial real estate loans. While not a large part of our portfolio during any period presented, we also lend on non-residential commercial real estate. Our commercial real estate loans are generally used to finance the purchase of established multi-tenant industrial, office and retail sites. At March 31, 2019, our commercial real estate portfolio had an average loan balance of $2.1 million, a weighted average loan to value of 56.7% and a weighted average debt service coverage ratio of 1.53, as compared to an average loan balance of $2.1 million, a weighted average loan to value of 57.0% and a weighted average debt service coverage ratio of 1.55 at December 31, 2018. We intend to continue to emphasize this product through marketing and cross-selling efforts; however, we do not anticipate that the composition of our loan portfolio will materially change as a result of these efforts.

37

Other. Other categories of loans included in our portfolio include construction loans and non-mortgage loans. Construction loans currently consist primarily of single family construction projects. The non-mortgage loans in our portfolio were provided in support of community investment efforts.

Total loans	$	8,290	$	5,554	$	6,065,240	$	6,079,084

Our fixed interest rate loans are primarily secured by single family residential properties in conjunction with our efforts to provide affordable housing to low-to-moderate income individuals. Our floating/adjustable rate loans are largely hybrid interest rate programs that provide an initial fixed term of 3 to 10 years and then convert to quarterly or semi-annual adjustments thereafter. As of March 31, 2019 and December 31, 2018, $3.7 billion and $3.6 billion, respectively, of our floating rate loans were at their floor rates. The weighted average minimum interest rate on these loans was 4.09% and 4.05% at March 31, 2019 and December 31, 2018, respectively. Hybrid adjustable rate loans still within their initial fixed term totaled $5.4 billion at both March 31, 2019 and 2018, respectively. These loans had a weighted average term to first repricing date of 3.64 years and 3.79 years at March 31, 2019 and 2018, respectively.

Asset Quality

Our primary objective is to maintain a high level of asset quality in our loan portfolio. We believe our underwriting practices and policies, established by experienced professionals, appropriately govern the risk profile for our loan portfolio. These policies are continually evaluated and updated as necessary. All loans are assessed and assigned a risk classification at origination based on underlying characteristics of the transaction such as collateral type, collateral cash flow, collateral coverage and borrower strength. We believe that we have a comprehensive methodology to proactively monitor our credit quality after origination. Particular emphasis is placed on our commercial portfolio where risk assessments are re-evaluated as a result of reviewing commercial property operating statements and borrower financials on at least an annual basis. Single family residential loans are subject to an annual credit score refresh. On an ongoing basis, we also monitor payment performance, delinquencies, and tax and property insurance compliance. We believe our practices facilitate the early detection and remediation of problems within our loan portfolio. Assigned risk classifications are an integral part of management assessing the adequacy of our allowance for loan losses. We periodically employ the use of an outside independent consulting firm to evaluate our underwriting and risk assessment process. Like other financial institutions, we are subject to the risk that our loan portfolio will be exposed to increasing pressures from deteriorating borrower credit due to general economic conditions.

Nonperforming assets. Our nonperforming assets consist of nonperforming loans and foreclosed real estate, if any. It is our policy to place a loan on non-accrual status in the event that the borrower is 90 days or more delinquent, unless the loan is well secured and in the process of collection, or earlier if the timely collection of contractual payments appears doubtful. Cash payments subsequently received on non-accrual loans are recognized as income only where the future collection of the remaining principal is considered by management to be probable. Loans are restored to accrual status only when the loan is less than 90 days delinquent and not in foreclosure, and the borrower has demonstrated the ability to make future payments of principal and interest.

Troubled debt restructures. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings ("TDRs"). Concessions could include reductions of interest rates, extension of the maturity date at a rate lower than current market rate for a new loan with similar risk, reduction of accrued interest, principal forgiveness, forbearance, or other material modifications. The assessment of whether a borrower is experiencing or will likely experience financial difficulty and whether a concession has been granted is highly subjective in nature, and management’s judgment is required when determining whether a modification is classified as a TDR.

The following table provides details of our nonperforming and restructured assets as of the dates presented and certain other related information:

(Dollars in thousands)	March 31, 2019			December 31, 2018
Non-accrual loans

Nonperforming assets to total assets	0.02		%	0.03		%
Nonperforming loans plus performing TDRs to total loans	0.08		%	0.11		%

When assessing whether a loan should be placed on non-accrual status because contractual payment appears doubtful, consideration is given to the information we collect on an annual basis from multifamily and commercial real estate borrowers to substantiate their future ability to repay principal and interest due on their loans as contractually agreed.

39

For the three months endedMarch 31, 2019,$3 thousand in interest income was recognized subsequent to a loan’s classification as non-accrual. For the three months endedMarch 31, 2018, no interest income was recognized subsequent to a loan’s classification as non-accrual. For the three months ended March 31, 2019 and 2018, the Company recorded $51 thousand and $54 thousand, respectively, of interest income related to performing TDR loans. Gross interest income that would have been recorded on non-accrual loans had they been current in accordance with their original terms was $22 thousand and $90 thousand during the three months ended March 31, 2019 and 2018, respectively.

Allowance for loan losses. Our allowance for loan losses is maintained at a level management believes is adequate to account for probable incurred credit losses in the loan portfolio as of the reporting date. We determine the allowance based on a quarterly evaluation of risk. That evaluation gives consideration to the nature of the loan portfolio, historical loss experience, known and inherent risks in the portfolio, the estimated value of any underlying collateral, adverse situations that may affect a borrower’s ability to repay, current economic and environmental conditions and risk assessments assigned to each loan as a result of our ongoing reviews of the loan portfolio. This process involves a considerable degree of judgment and subjectivity.

Our allowance is established through charges to the provision for loan losses. Loans, or portions of loans, deemed to be uncollectible are charged against the allowance. Recoveries of previously charged-off amounts are credited to our allowance for loan losses. The allowance is decreased by the reversal of prior provisions when the total allowance balance is deemed excessive for the risks inherent in the portfolio. The allowance for loan losses balance is neither indicative of the specific amounts of future charge-offs that may occur, nor is it an indicator of any future loss trends.

The following table provides information on the activity within the allowance for loan losses as of and for the periods indicated:

Investment Portfolio

Our investment portfolio is generally comprised of government agency securities which are high-quality liquid investments under Basel III. The portfolio is primarily maintained to serve as a contingent, on-balance sheet source of liquidity and as such, is kept unencumbered. We manage our investment portfolio according to written investment policies approved by our board of directors. Our investment strategy aims to maximize earnings while maintaining liquidity in securities with minimal credit risk and interest rate risk which is reflective in the yields obtained on those securities. Most of our securities are classified as available for sale, although we occasionally purchase long-term fixed rate mortgage backed securities or municipal securities for community reinvestment purposes and classify those as held to maturity. In addition, we have equity securities which consist of investments in the CRA Qualified Investment Fund.

At March 31, 2019, there was no issuer, other than U.S. government agencies where the aggregate book value or market value of such issuer’s securities held by the Company exceeded 10% of our stockholders’ equity.

Liabilities

Total liabilities increased $47.7 million, or 0.7%, to $6.4 billion at March 31, 2019 from December 31, 2018. The increase in total liabilities was primarily attributable to growth in our deposits of $80.8 million, or 1.6%, partially offset by a decrease in FHLB advances of $33.5 million, or 2.9%, compared to December 31, 2018.

Deposits

Representing 79.4% of our total liabilities as of March 31, 2019, deposits are our primary source of funding for our business operations. We believe we will maintain and grow our deposit customer base in the current rate environment based on our strong customer relationships, evidenced in part by increased deposits over recent years, as well as our reputation as a safe, sound, secure, "well-capitalized" institution and our commitment to excellent customer service. We are focused on growing our deposits by deepening our relationships with our existing loan and deposit customers and looking to expand our traditional product footprint with new emphasis placed on specialty, business and online affiliations, and transactional deposits. When competitively priced and/or for asset liability management purposes, we will supplement our deposits with wholesale deposits from deposit brokers.

Total deposits increased by $80.8 million, or 1.6%, to $5.1 billion at March 31, 2019 from $5.0 billion as of December 31, 2018. Wholesale deposits increased $143.6 million while retail deposits decreased $62.9 million. The decline in retail deposits was primarily attributable to our discipline in connection with deposit pricing.  As we focused on deposit pricing, we supplemented our fundings with wholesale deposits, which offered a competitive alternative during the current quarter. The proportion of time deposits in the total deposit portfolio has grown over the past year with our efforts to extend maturities, as well as customer preference for time deposits in the current rate environment. Given our consistently high retention rate at renewal and average age of our deposit relationships, we consider all our retail deposits, including time deposits, to be core deposits.

Our loan to deposit ratio was 120.91% and 122.59% at March 31, 2019 and December 31, 2018, respectively. It is common for us to operate with a loan to deposit ratio exceeding those commonly seen at other banks. Our higher than average ratio is attributed to our use of FHLB borrowings to supplement loan growth, as well as our preference to maintain a large proportion of our assets in real estate loans which generally provide a better yield than the high-quality

The Company had certificates of deposit that meet or exceed the FDIC Insurance limit of $250 thousand of $1.3 billion and $1.2 billion at March 31, 2019 and December 31, 2018, respectively. At the same dates, the Company had $611.2 million and $467.5 million, respectively, of brokered deposits.

FHLB Advances and Other Borrowings

In addition to deposits, we utilize short and long-term collateralized FHLB borrowings to fund our loan growth. FHLB advances can, at times, have attractive rates and we have commonly used them to strategically extend the duration of our liabilities as part of our interest rate risk management. Total FHLB advances decreased $33.5 million, or 2.9%, to $1.1 billion at March 31, 2019 compared to December 31, 2018. As of March 31, 2019 and December 31, 2018, the Bank pledged as collateral a $62.6 million FHLB letter of credit related to our multifamily securitization reimbursement obligation. In addition, the Bank pledged as collateral a $5.5 million FHLB letter of credit in connection with a time deposit with the State of California Treasurer's Office at March 31, 2019.

Historically, we have utilized other instruments such as trust preferred securities and senior debt at the bank holding company level as a source of capital for our Bank to support asset growth. We have established two trusts (the "Trusts") of which we own all the common securities, that have issued trust preferred securities, ("Trust Securities"), to investors in private placement transactions. The proceeds of the securities qualify as Tier 1 capital under the final Dodd Frank regulations for community banks with total assets less than $15 billion. In accordance with GAAP, the Trusts are not consolidated in our unaudited consolidated statements of financial condition but rather the common securities are included in our other assets and the junior subordinated debentures ("Notes") issued to the Trusts are shown as a liability. The following table is a summary of our outstanding Trust Securities and related Notes as of the dates indicated (dollars in thousands):

42

	March 31, 2019				December 31, 2018				Date	Maturity	Rate Index
Issuer	Amount		Rate		Amount		Rate		Issued	Date	(Quarterly Reset)
Luther Burbank Statutory Trust I	$	41,238	3.99	%	$	41,238	4.17	%	3/1/2006	6/15/2036	3 month LIBOR + 1.38%
Luther Burbank Statutory Trust II	$	20,619	4.23	%	$	20,619	4.41	%	3/1/2007	6/15/2037	3 month LIBOR + 1.62%

We have the right to defer payment of interest on the Notes at any time or from time to time for a period not exceeding five years provided that no extension period may extend beyond the stated maturity of the relevant Note. During any such extension period, distributions on the Trust Securities will also be deferred, and our ability to pay dividends on our common stock will be restricted.

We have entered into contractual arrangements which, taken collectively, fully and unconditionally guarantee payment of: (i) accrued and unpaid distributions required to be paid on the Trust Securities; (ii) the redemption price with respect to any Trust Securities called for redemption by the Trusts; and (iii) payments due upon a voluntary or involuntary dissolution, winding up or liquidation of the Trusts. The Trust Securities are mandatorily redeemable upon maturity of the Notes, or upon earlier redemption as provided in the indenture. We have the right to redeem the Notes purchased by the Trusts, in whole or in part, on or after the redemption date. As specified in the indenture, if the Notes are redeemed prior to maturity, the redemption price will be the principal amount and any accrued but unpaid interest.

In 2014, we issued senior debt totaling $95.0 million to qualified institutional investors. These senior notes are unsecured, carry a fixed interest coupon of 6.5%, pay interest only on a quarterly basis and mature on September 30, 2024. The senior debt is redeemable at any time prior to August 31, 2024, at a redemption price equal to the greater of (i) 100% of the principal amount, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on a semi-annual basis at the calculated rate for a U. S. Treasury security having a comparable remaining maturity plus 30 basis points, plus in each case accrued and unpaid interest. On or after September 1, 2024, the senior debt may be redeemed at 100% of the principal amount plus accrued and unpaid interest.

Our level of FHLB advances can fluctuate on a daily basis depending on our funding needs and the availability of other

43

sources of funds to satisfy those needs. Short-term advances allow us flexibility in funding particularly when planned transactions will yield an immediate large inflow of cash.

The following table sets forth the amount of short-term borrowings outstanding, comprised entirely of FHLB advances, as well as the weighted average interest rate thereon, as of the dates indicated:

Stockholders’ Equity

Stockholders’ equity totaled $588.3 million and $581.1 million at March 31, 2019 and December 31, 2018, respectively. The increase in stockholders' equity is primarily related to net income of $12.0 million, less dividends paid of $3.3 million and stock repurchases of $3.9 million during the three months endedMarch 31, 2019.

During the quarter ended March 31, 2019, the Company repurchased 393,000 shares in connection with its stock repurchase program at an average price of $9.88 per share and a total cost of $3.9 million.

Off-Balance Sheet Arrangements

In the normal course of business, we enter into various transactions that are not included in our unaudited consolidated statements of financial condition in accordance with GAAP. These transactions include commitments to extend credit in the ordinary course of business including commitments to fund new loans and undisbursed construction funds. While these commitments represent contractual cash requirements, a portion of these commitments to extend credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The following is a summary of our off-balance sheet commitments outstanding as of the dates presented.

(Dollars in thousands)	March 31, 2019		December 31, 2018
Commitments to fund loans held-for-investment	$	89,151	$	70,858

In connection with our Freddie Mac multifamily loan securitization, we entered into a reimbursement agreement pursuant to which we may be required to reimburse Freddie Mac for the first losses in the underlying loan portfolio, not to exceed 10% of the unpaid principal amount at settlement, or approximately $62.6 million. A $62.6 million letter of credit with the FHLB is pledged as collateral in connection with this reimbursement agreement. We have recorded a reserve for estimated losses with respect to the reimbursement obligation of $1.4 million as of both March 31, 2019 and December 31, 2018, which is included in other liabilities and accrued expenses on the unaudited consolidated statements of financial condition.

We guarantee the distributions and payments for redemption or liquidation of the Trust Securities issued by the Trusts to the extent of funds held by the Trusts. Although this guarantee is not separately recorded, the obligation underlying the guarantee is fully reflected on our unaudited consolidated statements of financial condition as junior subordinated debentures held by the Trusts. The junior subordinated debentures currently qualify as Tier 1 capital under the Federal Reserve capital adequacy guidelines. With the exception of our obligations in connection with its Trust Securities and the items detailed above, we have no other off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources, that is material to investors.

(2) We have one significant, long-term contract for core processing services which expires May 9, 2021. The actual obligation is unknown and dependent on certain factors including volume and activities. For purposes of this disclosure, future obligations are estimated using our current year to date average monthly expense extrapolated over the remaining life of the contract.

We believe that will we be able to meet our contractual obligations as they come due. Adequate cash levels are expected through profitability, repayments from loans and securities, deposit gathering activity, access to borrowing sources and periodic loan sales.

Liquidity Management and Capital Adequacy Liquidity Management

Liquidity refers to our capacity to meet our cash obligations at a reasonable cost. Our cash obligations require us to have cash flow that is adequate to fund loan growth and maintain on-balance sheet liquidity while meeting present and future obligations of deposit withdrawals, borrowing maturities and other contractual cash obligations. In managing our cash flows, management regularly confronts situations that can give rise to increased liquidity risk. These include funding mismatches, market constraints in accessing sources of funds and the ability to convert assets into cash. Changes in economic conditions or exposure to credit, market, operational, legal and reputational risks also could affect the bank’s liquidity risk profile and are considered in the assessment of liquidity management.

We continually monitor our liquidity position to ensure that our assets and liabilities are managed in a manner to meet all reasonably foreseeable short-term, long-term and strategic liquidity demands. Management has established a comprehensive management process for identifying, measuring, monitoring and controlling liquidity risk. Because of its critical importance to the viability of the Bank, liquidity risk management is fully integrated into our risk management processes. Critical elements of our liquidity risk management include: effective corporate governance consisting of oversight by the board of directors and active involvement by management; appropriate strategies, policies, procedures, and limits used to manage and mitigate liquidity risk; comprehensive liquidity risk measurement and monitoring systems including stress tests that are commensurate with the complexity of our business activities; active management of intraday liquidity and collateral; an appropriately diverse mix of existing and potential future funding sources; adequate levels of highly liquid marketable securities free of legal, regulatory, or operational impediments, that can be used to meet liquidity needs in stressful situations; comprehensive contingency funding plans that sufficiently address potential adverse liquidity events and emergency cash flow requirements; and internal controls and internal audit processes sufficient to determine the adequacy of the Bank’s liquidity risk management process.

Our liquidity position is supported by management of our liquid assets and liabilities and access to alternative sources of funds. Our liquidity requirements are met primarily through our deposits, FHLB advances and the principal and interest payments we receive on loans and investment securities. Cash on hand, cash at third party banks, investments available for sale and maturing or prepaying balances in our investment and loan portfolios are our most liquid assets. Other sources of liquidity that are routinely available to us include funds from retail and wholesale deposits, advances from the FHLB and proceeds from the sale of loans. Less commonly used sources of funding include borrowings from the FRB discount window, draws on established federal funds lines from unaffiliated commercial banks and the issuance of debt or equity securities. We believe we have ample liquidity resources to fund future growth and meet other cash

45

needs as necessary.

Our total deposits at March 31, 2019 and December 31, 2018 were $5.1 billion and $5.0 billion, respectively. Based on the values of loans pledged as collateral, we had $664.3 million of additional borrowing capacity with the FHLB at March 31, 2019. Based on the values of loans pledged as collateral, we had $176.6 million of borrowing capacity with the FRB at March 31, 2019. There were no outstanding advances with the FRB at March 31, 2019. In addition to the liquidity provided by the FHLB and FRB described above, we have established federal funds lines of credit with unaffiliated banks totaling $50.0 million at March 31, 2019, none of which was advanced at that date. In the ordinary course of business, we maintain correspondent bank accounts with unaffiliated banks which are used for normal business activity including ordering cash for our branch network, the purchase of investment securities and the receipt of principal and interest on those investments. Cash balances at correspondent banks, including amounts at the FRB, totaled $104.6 million at March 31, 2019.

The Company is a corporation separate and apart from our Bank and, therefore, must provide for its own liquidity, including liquidity required to meet its debt service requirements on its senior notes and junior subordinated debentures. The Company’s main source of cash flow is dividends declared and paid to it by the Bank. There are statutory and regulatory limitations that affect the ability of our Bank to pay dividends to the Company. We believe that these limitations will not impact our ability to meet our ongoing short-term cash obligations. For contingency purposes, the Company typically maintains a minimum level of cash to fund one year’s projected operating cash flow needs.

Capital Adequacy

We are subject to various regulatory capital requirements administered by the federal and state banking regulators. Our capital management consists of providing equity to support our current operations and future growth. Failure to meet minimum regulatory capital requirements may result in mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and off-balance sheet items as calculated under regulatory accounting policies. As of March 31, 2019 and December 31, 2018, we were in compliance with all applicable regulatory capital requirements, including the capital conservation buffer, and the Bank qualified as ‘‘well-capitalized’’ for purposes of the FDIC’s prompt corrective action regulations. At March 31, 2019, the capital conservation buffer was 2.50%.

The vast majority of our multifamily residential loans and single family residential loans are eligible for 50% risk-weighting for purposes of calculating our regulatory capital levels. To the extent that we increase our levels of commercial real estate lending collateralized by real estate other than multifamily residential properties, which loans would generally be 100% risk weighted, we would expect that our risk-based capital ratios would decline. Our leverage ratio is not impacted by the composition of our assets.

46

The following table presents our regulatory capital ratios as of the dates presented, as well as the regulatory capital ratios that are required by FDIC regulations to maintain ‘‘well-capitalized’’ status:

Impact of Inflation and Changing Prices

Our unaudited consolidated financial statements and related notes have been prepared in accordance with GAAP, which require the measurement of financial position and operating results in terms of historical dollars, without considering the changes in the relative purchasing power of money over time due to inflation. The impact of inflation is reflected in the increased cost of operations. Unlike most industrial companies, nearly all of our assets and liabilities are monetary in nature. As a result, interest rates have a greater impact on our performance than do the effects of general levels of inflation. Interest rates do not necessarily move in the same direction or to the same extent as the price of goods or services.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the exposure to unanticipated changes in net interest earnings or loss due to changes in the market value of assets and liabilities as a result of fluctuations in interest rates. As a financial institution, our primary market risk is interest rate risk. Interest rate risk is the risk to earnings and value arising from volatility in market interest rates. Interest rate risk arises from timing differences in the repricings and maturities of interest-earning assets and interest-bearing liabilities (reprice risk), changes in the expected maturities of assets and liabilities arising from embedded options, such as borrowers’ ability to prepay loans at any time and depositors’ ability to redeem certificates of deposit before maturity (option risk), changes in the shape of the yield curve where interest rates increase or decrease in a nonparallel fashion (yield curve risk), and changes in spread relationships between different yield curves, such as U.S. Treasuries and LIBOR (basis risk).

We manage market risk though our Asset Liability Council ("ALCO") which is comprised of senior management who are responsible for ensuring that board approved strategies, policy limits, and procedures for managing interest rate risk are appropriately executed within the designated lines of authority and responsibility. The ALCO meets monthly

47

to review, among other things, the composition of our assets and liabilities, the sensitivity of our assets and liabilities to interest rate changes, our actual and forecasted liquidity position, investment activity and our interest rate hedging transactions. The ALCO reports regularly to our board of directors. Our board reviews all policies impacting asset and liability management and establishes risk tolerance limits for business operations on at least an annual basis.

Interest rate risk management is an active process that encompasses monitoring loan and deposit flows complemented by investment and funding activities. Effective management of interest rate risk begins with understanding the dynamic characteristics of assets and liabilities and determining the appropriate interest rate risk posture given business forecasts, management objectives, market expectations, and policy constraints. In recognition of this, we actively manage our assets and liabilities to maximize our net interest income and return on equity, while managing our risk exposure and maintaining adequate liquidity and capital positions.

Given the nature of our loan and deposit activities, we are liability sensitive to volatility in interest rates. A liability sensitive position refers to a balance sheet position in which an increase in short-term interest rates is expected to generate lower net interest income, as rates paid on our interest-bearing liabilities would reprice upward more quickly than rates earned on our interest-earning assets, thus compressing our net interest margin. Conversely, an asset sensitive position refers to a balance sheet position in which an increase in short-term interest rates is expected to generate higher net interest income, as rates earned on our interest-earning assets would reprice upward more quickly than rates paid on our interest-bearing liabilities, thus expanding net interest margin.

We use two primary modeling techniques to assess our exposure to interest rates that simulate the earnings and valuation effects of variations in interest rates: Net Interest Income at Risk ("NII at Risk") and the Economic Value of Equity ("EVE"). These models require that we use numerous assumptions, including asset and liability pricing and repricing, future growth, prepayment rates, non-maturity deposit sensitivity and decay rates. These assumptions are inherently uncertain and, as a result, the models cannot precisely predict the fluctuations in market interest rates or precisely measure the impact of future changes in interest rates. Actual results will differ from the model’s simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and the application and timing of various management strategies.

Stress testing the balance sheet and net interest income using instantaneous parallel shock movements in the yield curve of -200 to 400 basis points is a regulatory and banking industry practice. However, these stress tests may not represent a realistic forecast of future interest rate movements in the yield curve.

Instantaneous parallel interest rate shock modeling is not a predictor of actual future performance of earnings. It is a financial metric used to manage interest rate risk, implement hedging transactions if the metric rises above policy limits for interest rate risk, and track the movement of the bank’s interest rate risk position over a historical time frame for comparison purposes.

Our earnings are a function of collecting both a credit risk premium on our loans and an interest rate risk premium on our balance sheet position. The purpose of these premiums being to diversify our earnings position with both credit risk and interest rate risk, which tend to be negatively correlated historically for the Bank. During weak economic times, such as the financial crisis of 2007-2008, our loan losses are higher than normal, but the Federal Reserve will generally reduce short-term interest rates in an attempt to stimulate the economy and add liquidity. As a result, our interest rate spread will generally increase during those periods. During strong economic times, when the Federal Reserve raises short-term interest rates to dampen economic activity, the Bank’s interest rate spread decreases. These periods are often indicative of inflation and real property value increases. As such, the decrease in net interest income is typically somewhat offset by declining loan losses in our loan portfolio. There is no guarantee, however, that the past countercyclical nature of our loan losses and our net interest spread declines will continue in the future.

On a quarterly basis, we measure and report NII at Risk to isolate the change in income related solely to interest-earning assets and interest-bearing liabilities. The following table illustrates the results of our NII at Risk analysis to determine the extent to which our net interest income over the following 12 months would change if prevailing interest rates increased or decreased by the specified amounts at March 31, 2019. It models instantaneous parallel shifts in market interest rates, implied by the forward yield curve over the next one year period.

Interest Rate Risk to Earnings (NII)
March 31, 2019
(Dollars in millions)
Change in Interest Rates (basis points)	$ Change NII	% Change NII
+400 BP	$(38.5)	(30.8)%
+300 BP	(25.5)	(20.4)%
+200 BP	(14.2)	(11.4)%
+100 BP	(6.0)	(4.8)%
-100 BP	5.7	4.5%
-200 BP	9.2	7.4%

The NII at Risk reported at March 31, 2019 reflects that our earnings are in a liability sensitive position in which an increase in interest rates is expected to generate lower net interest income. All NII stress tests measures were within our board established limits.

EVE measures the period end market value of assets minus the market value of liabilities and the change in this value as rates change. The EVE results included in the table below reflect the analysis reviewed monthly by management. It models instantaneous parallel shifts in market interest rates, implied by the forward yield curve. The EVE model calculates the market value of capital by taking the present value of all asset cash flows less the present value of all liability cash flows.

Interest Rate Risk to Capital (EVE)
March 31, 2019
(Dollars in millions)
Change in Interest Rates (basis points)	$ Change EVE	% Change EVE
+400 BP	$(343.2)	(55.5)%
+300 BP	(227.5)	(36.8)%
+200 BP	(131.4)	(21.3)%
+100 BP	(56.4)	(9.1)%
-100 BP	49.7	8.0%
-200 BP	99.3	16.1%

The EVE at Risk reported at March 31, 2019 reflects that our market value of capital is in a liability sensitive position in which an increase in interest rates is expected to generate lower market values of capital. All EVE stress tests measures were within our board established limits.

Certain shortcomings are inherent in the NII and EVE analyses presented above. Both the NII and EVE simulations include assumptions regarding balances, asset prepayment speeds, deposit repricing and runoff and interest rate relationships among balances that we believe to be reasonable for the various interest rate environments. Differences in actual occurrences from these assumptions, as well as nonparallel changes in the yield curve, may change our market risk exposure. Simulated results are not intended to be used as a forecast of the actual effect of changes in market interest rates on our results, but rather as a means to better plan and execute appropriate interest rate risk strategies.

Hedge Positions

In managing our market risk, our board of directors has authorized the ALCO to utilize interest rate caps and swaps to mitigate on-balance sheet interest rate risk in accordance with regulations and our internal policy. We use or expect to use interest rate caps and swaps as macro hedges against inherent rate sensitivity in our loan portfolio, other interest-earning assets and our interest-bearing liabilities. Positions for hedging purposes are undertaken as mitigation to exposure primarily from mismatches between assets and liabilities.

We typically utilize stand-alone interest rate caps and FHLB advances with embedded interest rate caps to hedge our liability sensitive interest rate risk position. The stand-alone caps are derivative instruments that have been designated as cash flow hedges of variable rate borrowings. These interest rate cap agreements are recorded at fair value with changes in fair value reflected in other comprehensive income and the fair value of these derivatives is recorded on

49

the unaudited consolidated statements of financial condition in other assets and other liabilities. The interest rate caps embedded in FHLB advances do not qualify as derivative contracts. The cost of these contracts is inseparable from the cost of the advances and, as such is included in interest expense in our unaudited consolidated statements of income.

The following table summarizes our one derivative instrument and FHLB borrowings with embedded caps utilized by us as interest rate risk hedge positions as of March 31, 2019:

Counterparty Credit Risk

Derivative contracts involve the risk of dealing with institutional derivative counterparties and their ability to meet contractual terms. Our policies require that counterparties must be approved by our ALCO and all positions over and above the minimum transfer amounts are secured by marketable securities or cash.

Item 4. Controls and Procedures

Management of the Company, with the participation of its Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness as of March 31, 2019, of the Company's disclosure controls and procedures, as defined in Rules 13a-15(e) and 15(d)-15(e) under the Exchange Act. Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective as of March 31, 2019 in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to management of the Company as appropriate to allow timely decisions regarding required disclosures.

Changes in Internal Control over Financial Reporting

There was no change in the Company's internal control over financial reporting that occurred during the Company's last fiscal quarter that has materially affected, or is reasonably likely to materially affect, such controls.

PART II.

Item 1. Legal Proceedings

From time to time, we are party to legal actions that are routine and incidental to our business. Given the nature, scope and complexity of the extensive legal and regulatory landscape applicable to our business, we, like all banking organizations, are subject to heightened regulatory compliance and legal risk. However, based on available information, management does not expect the ultimate disposition of any or a combination of these actions to have a material adverse effect on our business, financial condition and results of operation.

Item 1A. Risk Factors

There were no material changes from the risks disclosed in the Risk Factors section of the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Unregistered Sales of Equity Securities

(1) In August 2018, the Company's Board of Directors authorized the purchase of up to $15.0 million of the Company's common stock from August 17, 2018 through December 31, 2019 (the "Repurchase Program"), which was announced by press release and Current Report on Form 8-K on August 16, 2018 and August 17, 2018, respectively. Under the Repurchase Program, the Company may acquire its common stock in the open market or in privately negotiated transactions, including 10b5-1 plans.

NATURE OF OPERATIONS

NATURE OF OPERATIONS

Organization

Luther Burbank Corporation (the ‘‘Company’’), a California corporation headquartered in Santa Rosa, is the bank holding company for its wholly-owned subsidiary, Luther Burbank Savings (the "Bank"), and its wholly-owned subsidiary, Burbank Investor Services. The Company also owns Burbank Financial Inc., a real estate investment company, and all the common interests in Luther Burbank Statutory Trusts I and II, entities created to issue trust preferred securities.

The Bank conducts its business from its headquarters in Manhattan Beach, California. It has nine full service branches in California located in Sonoma, Marin, Santa Clara, and Los Angeles Counties and one full service branch in Washington located in King County. Additionally, there are seven loan production offices located throughout California, as well as a loan production office in Clackamas County, Oregon.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all footnotes as would be necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). However, these interim unaudited consolidated financial statements reflect all adjustments (consisting solely of normal recurring adjustments and accruals) which, in the opinion of management, are necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows for the interim periods presented. These unaudited consolidated financial statements have been prepared on a basis consistent with, and should be read in conjunction with, the audited consolidated financial statements as of and for the year ended December 31, 2018, and the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC, under the Securities and Exchange Act of 1934, (the “Exchange Act”). The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated.

The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results of operations that may be expected for any other interim period or for the year ending December 31, 2019.

The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry.

Use of Estimates

Management is required 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 unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the unaudited consolidated financial statements and the disclosures provided, and actual results could differ.

Earnings Per Share ("EPS")

Basic earnings per common share represents the amount of earnings for the period available to each share of common stock outstanding during the reporting period. Basic EPS is computed based upon net income divided by the weighted average number of common shares outstanding during the year. In determining the weighted average number of shares outstanding, vested restricted stock units are included. Diluted EPS represents the amount of earnings for the period available to each share of common stock outstanding including common stock that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares outstanding during each reporting period. Diluted EPS is computed based upon net income divided by the weighted average number of common shares outstanding during each period, adjusted for the effect of dilutive potential common shares, such as restricted stock awards and units, calculated using the treasury stock method.

New Financial Accounting Standards

FASB ASU 2016-01

In January 2016, the FASB issued ASU 2016-01 which provided guidance to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. This update contains several provisions, including but not limited to (1) requiring equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; (2) simplifying the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (3) eliminating the requirement to disclose the method(s) and significant assumptions used to estimate fair value; and (4) requiring separate presentation of financial assets and liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements. The update also changes certain financial statement disclosure requirements, including requiring disclosures of the fair value of financial instruments be made on the basis of exit price. The update was effective for public business entities ("PBEs") for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. As an emerging growth company, the Company was permitted to adopt this guidance on January 1, 2019 and, as a result, reclassified $399 thousand of unrealized losses on equity securities from other comprehensive income to retained earnings. Subsequent changes in the unrealized gain or loss on equity securities will be recorded through other noninterest income. Additionally, $11.4 million of equity securities were reclassified from available for sale securities to equity securities.

Net unrealized losses on available for sale investment securities are recorded as accumulated other comprehensive income within stockholders’ equity and totaled $2.8 million and $4.9 million, net of $1.1 million and $2.0 million in tax assets at March 31, 2019 and December 31, 2018, respectively. With the exception of the adoption of ASU 2016-01 as discussed in Note 1 to the unaudited consolidated financial statements, there were no sales or transfers of available for sale investment securities and no realized gains or losses on these securities during the three months endedMarch 31, 2019 and 2018.

The following tables summarize the gross unrealized losses and fair value of available for sale debt securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position:

At March 31, 2019, the Company held 80 residential MBS and CMOs of which 56 were in a loss position and 39 had been in a loss position for twelve months or more. The Company held 38 commercial MBS and CMOs of which 24 were in a loss position and 18 had been in a loss position for twelve months or more. The Company held 15 agency bonds of which 14 were in a loss position and had been for twelve months or more. The Company held 1 U.S. Treasury note at March 31, 2019. This note was in a loss position for greater than 12 months.

At December 31, 2018, the Company held 82 residential MBS and CMOs of which 45 were in a loss position and 40 had been in a loss position for twelve months or more. The Company held 34 commercial MBS and CMOs of which 23 were in a loss position and 16 had been in a loss position for twelve months or more. The Company held 14 agency bonds of which 13 were in a loss position and 12 had been in a loss position for twelve months or more. The Company held 1 U.S. Treasury note at December 31, 2018. This note was in a loss position for greater than 12 months.

The unrealized losses on the Company’s investments were caused by interest rate changes. In addition, the contractual cash flows of these investments are guaranteed by the U.S. government or agencies sponsored by the U.S. government. Accordingly, it is expected that the securities will not be settled at a price less than amortized cost. Because the decline in market value is attributable to changes in interest rates but not credit quality, and because the Company has the ability and intent to hold those investments until a recovery of fair value, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired at March 31, 2019 and December 31, 2018.

As of March 31, 2019 and December 31, 2018, there were no holdings of securities of any one issuer in an amount greater than 10% of stockholders' equity, other than the U.S. government and its agencies.

At March 31, 2019, the Company had 7 held to maturity residential MBS of which 4 were in a loss position and 4 had been in a loss position for twelve months or more. At December 31, 2018, the Company held 7 held to maturity residential MBS of which 6 were in a loss position and 3 had been in a loss position for twelve months or more.

The unrecognized losses on the Company’s held to maturity investments were caused by interest rate changes. In addition, the contractual cash flows of these investments are guaranteed by agencies sponsored by the U.S. government. Accordingly, it is expected that the securities will not be settled at a price less than amortized cost. Because the decline in market value is attributable to changes in interest rates but not credit quality, and because the Company has the ability and intent to hold those investments until maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2019 and December 31, 2018.

The following table summarizes the scheduled maturities of available for sale and held to maturity investment securities as of March 31, 2019:

	March 31, 2019
(Dollars in thousands)	Amortized Cost		Fair Value
Available for sale debt securities

The amortized cost and fair value of debt securities are shown by contractual maturity. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties. As such, mortgage backed securities and collateralized mortgage obligations are not included in the maturity categories above and instead are shown separately. No securities were pledged as of March 31, 2019 and December 31, 2018.

Equity Securities

Equity securities consist of investments in the CRA Qualified Investment Fund. At March 31, 2019 and December 31, 2018, the fair value of equity securities totaled $11.6 millionand $11.4 million, respectively. Prior to January 1, 2019, equity securities were included with available for sale investment securities and stated at fair value with unrealized gains and losses reported in other comprehensive income. As of January 1, 2019, $399 thousand of unrealized losses on equity securities were reclassified from other comprehensive income to retained earnings. Subsequent changes in fair value are recognized in other noninterest income and totaled $144 thousand during the three months ended March 31, 2019. There were no sales of equity securities during the three months ended March 31, 2019.

The Company assigns a risk rating to all loans and periodically performs detailed reviews of all such loans to identify credit risks and to assess the overall collectability of the portfolio. During these internal reviews, management monitors and analyzes the financial condition of borrowers and guarantors, as well as the financial performance and other characteristics of loan collateral. These credit quality indicators are used to assign a risk rating to each individual loan. The risk ratings can be grouped into six major categories, defined as follows:

Pass assets are those which are performing according to contract and have no existing or known weaknesses deserving of management’s close attention. The basic underwriting criteria used to approve the loans are still valid, and all payments have essentially been made as planned.

Watch assets are expected to have an event occurring in the next 90 to 120 days that will lead to a change in risk rating with the change being either favorable or unfavorable. These assets require heightened monitoring of the event by management.

Special mention assets have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special mention assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

Substandard assets are inadequately protected by the current net worth and/or paying capacity of the obligor or by the collateral pledged. These assets have well-defined weaknesses: the primary source of repayment is gone or severely impaired (i.e., bankruptcy or loss of employment) and/or there has been a deterioration in collateral value. In addition, there is the distinct possibility that the Company will sustain some loss, either directly or indirectly (i.e., the cost of monitoring), if the deficiencies are not corrected. A deterioration in collateral value alone does not mandate that an asset be adversely classified if such factor does not indicate that the primary source of repayment is in jeopardy.

Doubtful assets have the weaknesses of those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable based on current facts, conditions and values.

Loss assets are considered uncollectible and of such little value that their continuance as assets, without establishment of a specific valuation allowance or charge-off, is not warranted. This classification does not necessarily mean that an asset has absolutely no recovery or salvage value; but rather, it is not practical or desirable to defer writing off a basically worthless asset (or portion thereof) even though partial recovery may be affected in the future.

The following tables summarize the loan portfolio allocated by management’s internal risk ratings at March 31, 2019 and December 31, 2018:

NONPERFORMING ASSETS

Nonperforming assets include nonperforming loans plus real estate owned. The Company’s nonperforming assets at March 31, 2019 and December 31, 2018 are indicated below:

(Dollars in thousands)	March 31, 2019		December 31, 2018

Real estate owned	—		—
Total nonperforming assets	$	1,506	$	2,164

Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of a non-accrual loan is deemed to be fully collectible. If there’s doubt regarding the collectability of the loan, then any interest payments received are applied to principal. Interest income was recognized on a cash basis on two non-accrual loans during the three months ended March 31, 2019 totaling $3 thousand. No interest income was recognized on non-accrual loans during the three months ended March 31, 2018. Contractual interest not accrued on nonperforming loans during the three months ended March 31, 2019 and 2018 totaled $22 thousand and $90 thousand, respectively.

Generally, nonperforming loans are considered impaired, because the repayment of the loan will not be made in accordance with the original contractual agreement.

JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES

Debt Disclosure [Abstract]

JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES

JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES

The Company formed two wholly-owned trust companies (the ‘‘Trusts’’) which issued guaranteed preferred beneficial interests (the "Trust Securities") in the Company’s junior subordinated deferrable interest debentures (the "Notes"). The Company is not considered the primary beneficiary of the Trusts and therefore, the Trusts are not consolidated in the Company’s financial statements, but rather the junior subordinated debentures are shown as a liability. The Company’s investment in the common securities of the Trusts, totaling $1.9 million, is included in other assets on the unaudited consolidated statements of financial condition. The sole asset of the Trusts are the Notes that they hold.

The Trusts have invested the proceeds of such Trust Securities in the Notes. Each of the Notes has an interest rate equal to the corresponding Trust Securities distribution rate. The Company has the right to defer payment of interest on the Notes at any time or from time to time for a period not exceeding five years provided that no extension period may extend beyond the stated maturity of the relevant Notes. During any such extension period, distributions on the Trust Securities will also be deferred, and the Company’s ability to pay dividends on its common stock will be restricted.

The Company has entered into contractual arrangements which, taken collectively, fully and unconditionally guarantee payment of: (i) accrued and unpaid distributions required to be paid on the Trust Securities; (ii) the redemption price with respect to any Trust Securities called for redemption by the Trusts; and (iii) payments due upon a voluntary or involuntary dissolution, winding up or liquidation of the Trusts. The Trust Securities are mandatorily redeemable upon maturity of the Notes, or upon earlier redemption as provided in the indenture. The Company has the right to redeem the Notes purchased by the Trusts, in whole or in part, on or after the redemption date. As specified in the indenture, if the Notes are redeemed prior to maturity, the redemption price will be the principal amount and any accrued but unpaid interest.

The following table is a summary of the outstanding Trust Securities and Notes at March 31, 2019 and December 31, 2018 (dollars in thousands):

STOCK BASED COMPENSATION

STOCK BASED COMPENSATION

The Company’s stock based compensation consists of restricted stock awards ("RSAs") and restricted stock units ("RSUs") granted under the Luther Burbank Corporation Omnibus Equity and Incentive Compensation Plan ("Omnibus Plan"). In connection with its initial public offering ("IPO") in December 2017, the Company granted RSAs and RSUs to employees and nonemployee directors which all vest ratably over three years. At the same time, the Company granted RSUs in exchange for unvested phantom stock awards held by employees and all vested and unvested phantom stock awards held by nonemployee directors on a per share basis. The RSUs were subjected to the same vesting schedule and deferral elections that existed for the original phantom stock awards.

Awards granted subsequent to the IPO vest ratably over one year for nonemployee directors and ratably over three to four years for employees.

All RSAs and RSUs were granted at the fair value of the common stock at the time of the award. The RSAs and RSUs are considered fixed awards as the number of shares and fair value are known at the date of grant and the fair value at the grant date is amortized over the vesting and/or service period.

Non-cash stock compensation expense recognized for RSAs and RSUs for the three months ended March 31, 2019 and 2018 totaled $838 thousand and $1.0 million, respectively. The fair value of RSAs and RSUs that vested during the three months ended March 31, 2019 and 2018 totaled $5.7 million and $1.5 million, respectively.

As of March 31, 2019 and December 31, 2018, there was $6.3 million and $4.3 million of unrecognized compensation expense related to 758,182 and 985,869 unvested RSAs and RSUs, respectively. As of March 31, 2019 and December 31, 2018, this expense is expected to be recognized over a weighted average period of 2.12 years and 1.91 years, respectively. As of March 31, 2019 and December 31, 2018, 522,464 and 169,490 shares, respectively, of RSUs were vested and remain unsettled per the original deferral elections.

The following table summarizes share information about restricted stock awards and restricted stock units:

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Fair Value Measurements

Fair Value Hierarchy

The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Valuations within these levels are based upon:

Level 1 - Quoted market prices for identical instruments traded in active exchange markets.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable or can be corroborated by observable market data.

Level 3 - Model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use on pricing the asset or liability. Valuation techniques include management judgment and estimation which may be significant.

Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company.

Management monitors the availability of observable market data to assess the appropriate classification of assets and liabilities within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities, or total earnings.

The following methods and assumptions were used to estimate the fair value of financial instruments:

For cash and cash equivalents, accrued interest receivable and payable, demand deposits and short-term borrowings, the carrying amount is estimated to be fair value. The fair value of accrued interest receivable/payable balances are determined using inputs and fair value measurements commensurate with the asset or liability from which the accrued interest is generated.

Fair values for available for sale and held to maturity debt securities, which include primarily debt securities issued by U.S. government sponsored agencies, are based on quoted market prices for similar securities.

Fair values for equity securities, which consist of investments in the CRA Qualified Investment Fund are based on quoted market prices for similar securities.

Loans are valued using the exit price notion. The fair value is estimated using market quotes for similar assets or the present value of future cash flows, discounted using a market rate for similar products and giving consideration to estimated prepayment risk and credit risk. The fair value of loans is determined utilizing estimates resulting in a Level 3 classification.

Impaired loans are measured for impairment based on the present value of expected future cash flows discounted at the loans' effective interest rate, except that as a practical expedient, the Company may measure impairment based on a loan’s observable market price, or the fair value of the collateral (net of estimated costs to sell) if the loan is collateral dependent. The fair value of impaired loans is determined utilizing estimates resulting in a Level 3 classification.

It was not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability.

The fair value of servicing rights is determined using a valuation model that utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against available market data.

The fair values of derivatives are based on valuation models using observable market data as of the measurement date.

Fair values for fixed-rate certificates of deposit are estimated using discounted cash flow analyses using interest rates offered at each reporting date by the Company for certificates with similar remaining maturities. For deposits with no contractual maturity, the fair value is assumed to equal the carrying value.

The fair value of FHLB advances is estimated based on discounting the future cash flows using the market rate currently offered for similar terms.

The fair value of subordinated debentures is based on an indication of value provided by a third-party broker.

For senior debt, the fair value is based on an indication of value provided by a third-party broker.

VARIABLE INTEREST ENTITIES (VIE)

Organization, Consolidation and Presentation of Financial Statements [Abstract]

VARIABLE INTEREST ENTITIES (VIE)

VARIABLE INTEREST ENTITIES ("VIE")

The Company is involved with VIEs through its loan securitization activities. The Company evaluated its association with VIEs for consolidation purposes. Specifically, a VIE is to be consolidated by its primary beneficiary, the entity that has both the power to direct the activities that most significantly impact the VIE and a variable interest that could potentially be significant to the VIE. A variable interest is a contractual, ownership or other interest whose value fluctuates with the changes in the value of the VIE's assets and liabilities. The assessment includes an evaluation of the Company's continuing involvement with the VIE and the nature and significance of its variable interests.

Multifamily loan securitization

With respect to the securitization transaction with Freddie Mac which settled September 27, 2017, the Company's variable interests reside with a reimbursement agreement entered into with Freddie Mac that obligates the Bank to reimburse Freddie Mac for any defaulted contractual principal and interest payments identified after the ultimate resolution of the defaulted loans. Such reimbursement obligations are not to exceed 10% of the original principal amount of the loans comprising the securitization pool. As part of the securitization transaction, the Bank released all servicing obligations and rights to Freddie Mac who was designated as the Master Servicer. As Master Servicer, Freddie Mac appointed the Bank with sub-servicing obligations, which include obligations to collect and remit payments of principal and interest, manage payments of taxes and insurance, and otherwise administer the underlying loans. The servicing of defaulted loans and foreclosed loans was assigned to a separate third party entity, independent of the Bank and Freddie Mac. Freddie Mac, in its capacity as Master Servicer, can terminate the Bank in its role as sub-servicer and direct such responsibilities accordingly. In evaluating the variable interests and continuing involvement in the VIE, the Company determined that it does not have the power to make significant decisions or direct the activities that most significantly impact the economic performance of the VIE's assets and liabilities. As sub-servicer of the loans, the Bank does not have the authority to make significant decisions that influence the value of the VIE's net assets and therefore, is not the primary beneficiary of the VIE. Therefore, the Company determined that the VIE associated with the multifamily securitization should not be included in the consolidated financial statements of the Bank.

The Company believes its maximum exposure to loss as a result of involvement with the VIE associated with the securitization under the reimbursement agreement executed with Freddie Mac is 10% of the original principal amount of the loans comprising the securitization pool, or $62.6 million. The reserve for estimated losses with respect to the reimbursement obligation totaled $1.4 million as of both March 31, 2019 and December 31, 2018, respectively, based upon an analysis of quantitative and qualitative data over the underlying loans included in the securitization pool. No disbursements have been made in connection with the reimbursement obligation.

Transfers and Servicing [Abstract]

LOAN SALE AND SECURITIZATION ACTIVITIES

LOAN SALE AND SECURITIZATION ACTIVITIES

The Company sells originated and acquired loans as part of its business operations and overall management of liquidity, assets and liabilities, and financial performance. The transfer of loans is executed in securitization or sale transactions. With respect to sale transactions, the Company's continuing involvement may or may not include ongoing servicing responsibilities and general representations and warranties. With respect to securitization sales, the Company executed its first and only transaction on September 27, 2017 with Freddie Mac. The transaction involved the sale of $626 million in originated multifamily loans through a Freddie Mac sponsored transaction. The Company's continuing involvement includes sub-servicing responsibilities, general representations and warranties, and reimbursement obligations.

As sub-servicer for Freddie Mac, the Bank is required to maintain a minimum net worth in accordance with GAAP of not less than $2.0 million. If Luther Burbank Savings’ capital were to fall below this threshold, Freddie Mac would have the authority to terminate and assume the Bank’s sub-servicing duties. At March 31, 2019, the Bank’s net worth was $723.6 million.

General representations and warranties associated with loan sales and securitization sales require the Bank to uphold various assertions that pertain to the underlying loans at the time of the transaction, including, but not limited to, compliance with relevant laws and regulations, absence of fraud, enforcement of liens, no environmental damages, and maintenance of relevant environmental insurance. Such representations and warranties are limited to those that do not meet the quality represented at the transaction date and do not pertain to a decline in value or future payment defaults. In circumstances where the Bank breaches its representations and warranties, the Bank would generally be required to cure such instances through a repurchase or substitution of the subject loan(s).

With respect to the securitization transaction, the Bank also has continuing involvement through a reimbursement agreement executed with Freddie Mac. To the extent the ultimate resolution of defaulted loans results in contractual principal and interest payments that are deficient, the Bank is obligated to reimburse Freddie Mac for such amounts, not to exceed 10% of the original principal amount of the loans comprising the securitization pool at the closing date of September 27, 2017.

The following table provides cash flows associated with the Company's loan sale activities:

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

Financial Instruments With Off-Balance Sheet Risk

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments represent commitments to originate fixed and variable rate loans and loans in process, and involve, to varying degrees, elements of interest rate risk and credit risk in excess of the amount recognized in the Company’s consolidated statements of financial condition. The Company’s exposure to credit loss in the event of nonperformance by the other party for commitments to extend credit and lines of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments to originate loans as it does for on-balance sheet instruments.

Commitments to fund loans are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have expiration dates or other termination clauses. In addition, external market forces may impact the probability of commitments being exercised; therefore, total commitments outstanding do not necessarily represent future cash requirements.

At March 31, 2019 and December 31, 2018, the Company had outstanding commitments of approximately $89.2 million and $70.9 million, respectively, for loans. Unfunded loan commitment reserves totaled $24 thousand and $52 thousand at March 31, 2019 and December 31, 2018, respectively.

Operating Leases

The Company leases various office premises under long-term operating lease agreements. These leases expire between 2019 and 2029, with certain leases containing either three, five or ten year renewal options. At March 31, 2019, minimum commitments under these non-cancellable leases before considering renewal options are (dollars in thousands):

April 1 - December 31, 2019	$	3,965
Year ending December 31, 2020	3,952
Year ending December 31, 2021	3,484
Year ending December 31, 2022	2,526
Year ending December 31, 2023	1,257
Thereafter	1,289
Total	$	16,473

Rent expense under operating leases was $1.3 million for both the three months ended March 31, 2019 and 2018. Sublease income earned was $177 thousand and $201 thousand for the three months ended March 31, 2019 and 2018, respectively.

Contingencies

At present, there are no pending or threatened proceedings against the Company which, if determined adversely, would have a material effect on the Company’s business, financial position, results of operations, cash flows or stock price. In the ordinary course of operations, the Company may be party to various legal proceedings.

Correspondent Banking Agreements

The Company maintains funds on deposit with other federally insured financial institutions under correspondent banking agreements. These balances are insured by the FDIC up to $250 thousand. At March 31, 2019 and December 31, 2018, the Company had $1.1 million and $736 thousand, respectively, in cash balances exceeding the insured amounts.

Accounting Policies [Abstract]

Basis of Accounting

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all footnotes as would be necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). However, these interim unaudited consolidated financial statements reflect all adjustments (consisting solely of normal recurring adjustments and accruals) which, in the opinion of management, are necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in stockholders’ equity and cash flows for the interim periods presented. These unaudited consolidated financial statements have been prepared on a basis consistent with, and should be read in conjunction with, the audited consolidated financial statements as of and for the year ended December 31, 2018, and the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC, under the Securities and Exchange Act of 1934, (the “Exchange Act”). The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated.

The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results of operations that may be expected for any other interim period or for the year ending December 31, 2019.

The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry.

Use of Estimates

Use of Estimates

Management is required 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 unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the unaudited consolidated financial statements and the disclosures provided, and actual results could differ.

Earnings Per Share

Earnings Per Share ("EPS")

Basic earnings per common share represents the amount of earnings for the period available to each share of common stock outstanding during the reporting period. Basic EPS is computed based upon net income divided by the weighted average number of common shares outstanding during the year. In determining the weighted average number of shares outstanding, vested restricted stock units are included. Diluted EPS represents the amount of earnings for the period available to each share of common stock outstanding including common stock that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares outstanding during each reporting period. Diluted EPS is computed based upon net income divided by the weighted average number of common shares outstanding during each period, adjusted for the effect of dilutive potential common shares, such as restricted stock awards and units, calculated using the treasury stock method.

New Financial Accounting Standards

New Financial Accounting Standards

FASB ASU 2016-01

In January 2016, the FASB issued ASU 2016-01 which provided guidance to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. This update contains several provisions, including but not limited to (1) requiring equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; (2) simplifying the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (3) eliminating the requirement to disclose the method(s) and significant assumptions used to estimate fair value; and (4) requiring separate presentation of financial assets and liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements. The update also changes certain financial statement disclosure requirements, including requiring disclosures of the fair value of financial instruments be made on the basis of exit price. The update was effective for public business entities ("PBEs") for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. As an emerging growth company, the Company was permitted to adopt this guidance on January 1, 2019 and, as a result, reclassified $399 thousand of unrealized losses on equity securities from other comprehensive income to retained earnings. Subsequent changes in the unrealized gain or loss on equity securities will be recorded through other noninterest income. Additionally, $11.4 million of equity securities were reclassified from available for sale securities to equity securities.

Fair Value Measurements

Fair Value Measurements

Fair Value Hierarchy

The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Valuations within these levels are based upon:

Level 1 - Quoted market prices for identical instruments traded in active exchange markets.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable or can be corroborated by observable market data.

Level 3 - Model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use on pricing the asset or liability. Valuation techniques include management judgment and estimation which may be significant.

Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company.

Management monitors the availability of observable market data to assess the appropriate classification of assets and liabilities within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities, or total earnings.

The following methods and assumptions were used to estimate the fair value of financial instruments:

For cash and cash equivalents, accrued interest receivable and payable, demand deposits and short-term borrowings, the carrying amount is estimated to be fair value. The fair value of accrued interest receivable/payable balances are determined using inputs and fair value measurements commensurate with the asset or liability from which the accrued interest is generated.

Fair values for available for sale and held to maturity debt securities, which include primarily debt securities issued by U.S. government sponsored agencies, are based on quoted market prices for similar securities.

Fair values for equity securities, which consist of investments in the CRA Qualified Investment Fund are based on quoted market prices for similar securities.

Loans are valued using the exit price notion. The fair value is estimated using market quotes for similar assets or the present value of future cash flows, discounted using a market rate for similar products and giving consideration to estimated prepayment risk and credit risk. The fair value of loans is determined utilizing estimates resulting in a Level 3 classification.

Impaired loans are measured for impairment based on the present value of expected future cash flows discounted at the loans' effective interest rate, except that as a practical expedient, the Company may measure impairment based on a loan’s observable market price, or the fair value of the collateral (net of estimated costs to sell) if the loan is collateral dependent. The fair value of impaired loans is determined utilizing estimates resulting in a Level 3 classification.

It was not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability.

The fair value of servicing rights is determined using a valuation model that utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against available market data.

The fair values of derivatives are based on valuation models using observable market data as of the measurement date.

Fair values for fixed-rate certificates of deposit are estimated using discounted cash flow analyses using interest rates offered at each reporting date by the Company for certificates with similar remaining maturities. For deposits with no contractual maturity, the fair value is assumed to equal the carrying value.

The fair value of FHLB advances is estimated based on discounting the future cash flows using the market rate currently offered for similar terms.

The fair value of subordinated debentures is based on an indication of value provided by a third-party broker.

For senior debt, the fair value is based on an indication of value provided by a third-party broker.
