Organization and Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Jun. 30, 2018
Accounting Policies [Abstract] |
Consolidation | The consolidated financial statements include the accounts of Provident Financial Holdings, Inc., and its wholly owned subsidiary, Provident Savings Bank, F.S.B. (collectively, the “Corporation”). All inter-company balances and transactions have been eliminated.
Use of estimates | Use of estimates The accounting and reporting policies of the Corporation conform to generally accepted accounting principles in the United States of America (“GAAP”). The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and of the loan repurchase reserve and the valuation of investment securities available for sale, loans held for sale, loans held for investment at fair value, deferred tax assets, loan servicing assets, real estate owned, derivative financial instruments and deferred compensation costs.
Cash and cash equivalents | Cash and cash equivalents Cash and cash equivalents include cash on hand and due from banks, as well as overnight deposits placed at correspondent banks.
Investment securities | Investment securities The Corporation classifies its qualifying investments as available for sale or held to maturity. The Corporation classifies investments as held to maturity when it has the ability and it is management’s positive intent to hold such securities to maturity. Securities held to maturity are carried at amortized historical cost. All other securities are classified as available for sale and are carried at fair value. Fair value generally is determined based upon quoted market prices. Changes in net unrealized gains (losses) on securities available for sale are included in accumulated other comprehensive income, net of tax. Gains and losses on sale or dispositions of investment securities are included in non-interest income and are determined using the specific identification method. Purchase premiums and discounts are amortized over the expected average life of the securities using the effective interest method. Investment securities are reviewed annually for possible other-than-temporary impairment (“OTTI”). For debt securities, an OTTI is evident if the Corporation intends to sell the debt security or will more likely than not be required to sell the debt security before full recovery of the entire amortized cost basis is realized. However, even if the Corporation does not intend to sell the debt security and will not likely be required to sell the debt security before recovery of its entire amortized cost basis, the Corporation must evaluate expected cash flows to be received and determine if a credit loss has occurred. In the event of a credit loss, the credit component of the impairment is recognized within non-interest income and the non-credit component is recognized through accumulated other comprehensive income, net of tax.
Loans held for sale | oans held for sale Loans held for sale consist primarily of long-term fixed-rate loans secured by first trust deeds on single-family residences, the majority of which are Federal Housing Administration (“FHA”), United States Department of Veterans Affairs (“VA”), Fannie Mae and Freddie Mac loan products. The loans are generally offered to customers located in (a) Southern California, primarily in Riverside and San Bernardino counties, commonly known as the Inland Empire, and Orange, Los Angeles, San Diego and other surrounding counties and (b) Northern California, primarily Alameda, Placer, San Luis Obispo and other surrounding counties. The loans have been hedged with loan sale commitments, To-Be-Announced ("TBA") Mortgage-Backed-Securities ("MBS") trades and option contracts. The loan sale settlement period is generally between 20 to 30 days from the date of the loan funding. The Corporation adopted ASC 820, “Fair Value Measurements and Disclosures,” and elected the fair value option (ASC 825, “Financial Instruments”) on loans held for sale.
Loans held for investment | oans held for investment Loans held for investment consist of long-term adjustable rate loans secured by first trust deeds on single-family residences, other residential property, commercial property and land. Additionally, multi-family and commercial real estate loans have become a substantial part of loans held for investment, and comprised 64% and 63% at June 30, 2018 and 2017, respectively. These loans are generally offered to customers and businesses located in the same areas of Southern and Northern California described above. Net loan origination fees and certain direct origination expenses are deferred and amortized to interest income over the contractual life of the loan using the effective interest method. Amortization is discontinued for non-performing loans. Interest receivable represents, for the most part, the current month’s interest, which will be included as a part of the borrower’s next monthly loan payment. Interest receivable is accrued only if deemed collectible. Loans are placed on non-performing status when they become 90 days past due or if the loan is deemed impaired. When a loan is placed on non-performing status, interest accrued but not received is reversed against interest income. Interest income on non-performing loans is subsequently recognized only to the extent that cash is received and the principal balance is deemed collectible. If the principal balance is not deemed collectible, the entire payment received (principal and interest) is applied to the outstanding loan balance. Non-performing loans that become current as to both principal and interest are returned to accrual status after demonstrating satisfactory payment history (usually six consecutive months) and when future payments are expected to be collected.
Allowance for loan losses | llowance for loan losses The allowance for loan losses involves significant judgment and assumptions by management, which has a material impact on the carrying value of net loans. Management considers the accounting estimate related to the allowance for loan losses a critical accounting estimate because it is highly susceptible to changes from period to period, requiring management to make assumptions about probable incurred losses inherent in the loan portfolio at the balance sheet date. The impact of a sudden large loss could deplete the allowance and require increased provisions to replenish the allowance, which would negatively affect earnings. The allowance is based on two principles of accounting: (i) ASC 450, “Contingencies,” which requires that losses be accrued when they are probable of occurring and can be estimated; and (ii) ASC 310, “Receivables,” which requires that losses be accrued for non-performing loans that may be determined on an individually evaluated basis or based on an aggregated pooling method where the allowance is developed primarily by using historical charge-off statistics. The allowance has two components: collectively evaluated allowances and individually evaluated allowances. Each of these components is based upon estimates that can change over time. The allowance is based on historical experience and, as a result, can differ from actual losses incurred in the future. Additionally, differences may result from qualitative factors such as unemployment data, gross domestic product, interest rates, retail sales, the value of real estate and real estate market conditions. The historical data is reviewed at least quarterly and adjustments are made as needed. Various techniques are used to arrive at an individually evaluated allowance, including discounted cash flows and the fair market value of collateral. The use of these techniques is inherently subjective and the actual losses could be greater or less than the estimates. Management considers, based on currently available information, the allowance for loan losses sufficient to absorb probable losses inherent in loans held for investment.
Allowance for unfunded loan commitments | llowance for unfunded loan commitments The Corporation maintains the allowance for unfunded loan commitments at a level that is adequate to absorb estimated probable losses related to these unfunded credit facilities. The Corporation determines the adequacy of the allowance based on periodic evaluations of the unfunded credit facilities, including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The allowance for unfunded loan commitments is recorded in other liabilities on the Consolidated Statements of Financial Condition. Net adjustments to the allowance for unfunded loan commitments are included in other non-interest expense on the Consolidated Statements of Operations.
Troubled debt restructuring | roubled debt restructuring (“restructured loans”) A restructured loan is a loan which the Corporation, for reasons related to a borrower’s financial difficulties, grants a concession to the borrower that the Corporation would not otherwise consider. These financial difficulties include, but are not limited to, the borrowers default status on any of their debts, bankruptcy and recent changes in their financial circumstances (loss of job, etc.). The loan terms which have been modified or restructured due to a borrower’s financial difficulty, may include but are not limited to:
a) | A reduction in the stated interest rate.
b) | An extension of the maturity at an interest rate below market.
c) | A reduction in the accrued interest.
d) | Extensions, deferrals, renewals and rewrites.
e) | Loans that have been discharged in a Chapter 7 Bankruptcy that have not been reaffirmed by the borrower.
To qualify for restructuring, a borrower must provide evidence of creditworthiness such as, current financial statements, most recent income tax returns, current paystubs, current W-2s, and most recent bank statements, among other documents, which are then verified by the Corporation. The Corporation re-underwrites the loan with the borrower's updated financial information, new credit report, current loan balance, new interest rate, remaining loan term, updated property value and modified payment schedule, among other considerations, to determine if the borrower qualifies. The Corporation measures the allowance for loan losses of restructured loans based on the difference between the loan's original carrying amount and the present value of expected future cash flows discounted at the original effective yield of the loan. Based on the Office of the Comptroller of the Currency's ("OCC") guidance with respect to restructured loans and to conform to general practices within the banking industry, the Corporation maintains certain restructured loans on accrual status, provided there is reasonable assurance of repayment and performance, consistent with the modified terms based upon a current, well-documented credit evaluation. Other restructured loans are classified as “Substandard” and placed on non-performing status. The Corporation upgrades restructured single-family loans to the pass category if the borrower has demonstrated satisfactory contractual payments for at least six consecutive months or 12 consecutive months for those loans that were restructured more than once. Once the borrower has demonstrated satisfactory contractual payments beyond 12 consecutive months, the loan is no longer categorized as a restructured loan. In addition to the payment history described above; multi-family, commercial real estate, construction and commercial business loans must also demonstrate a combination of corroborating characteristics to be upgraded, such as: satisfactory cash flow, satisfactory guarantor support, and additional collateral support, among others. N
Non-performing loans | on-performing loans The Corporation assesses loans individually and classifies as non-performing loans when the accrual of interest has been discontinued, loans have been restructured or management has serious doubts about the future collectibility of principal and interest, even though the loans may currently be performing. Factors considered in determining classification include, but are not limited to, expected future cash flows, the financial condition of the borrower and current economic conditions. The Corporation measures each non-performing loan based on ASC 310, establishes a collectively evaluated or individually evaluated allowance and charges off those loans or portions of loans deemed uncollectible.
Non-performing loans | The Corporation records payments on non-performing loans utilizing the cash basis or cost recovery method of accounting during the periods when the loans are on non-performing status.
Real estate owned | eal estate owned Real estate acquired through foreclosure is initially recorded at the fair value of the real estate acquired, less estimated selling costs. Subsequent to foreclosure, the Corporation charges current earnings for estimated losses if the carrying value of the property exceeds its fair value. Gains or losses on the sale of real estate are recognized upon disposition of the property. Costs relating to improvement, maintenance and repairs of the property are expensed as incurred under gain (loss) on sale and operations of real estate owned acquired in the settlement of loans within the Consolidated Statements of Operations.
Impairment of long-lived assets | mpairment of long-lived assets The Corporation reviews its long-lived assets for impairment annually or when events or circumstances indicate that the carrying amount of these assets may not be recoverable. Long-lived assets include buildings, land, fixtures, furniture and equipment. An asset is considered impaired when the expected discounted cash flows over the remaining useful life are less than the net book value. When impairment is indicated for an asset, the amount of impairment loss is the excess of the net book value over its fair value.
Premises and equipment | remises and equipment Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed primarily on a straight-line basis over the estimated useful lives as follows:
| Buildings | 10 to 40 years
| Furniture and fixtures | 3 to 10 years
| Automobiles | 3 to 5 years
| Computer equipment | 3 to 5 years
Leasehold improvements are amortized over the lesser of their respective lease terms or the useful life of the improvement, which ranges from one to 10 years. Maintenance and repair costs are charged to operations as incurred.
Income taxes | ncome taxes The Corporation accounts for income taxes in accordance with ASC 740, “Income Taxes.” ASC 740 requires the affirmative evaluation that it is more likely than not, based on the technical merits of a tax position, that an enterprise is entitled to economic benefits resulting from positions taken in income tax returns. If a tax position does not meet the more-likely-than-not recognition threshold, the benefit of that position is not recognized in the financial statements. ASC 740 requires that when determining the need for a valuation allowance against a deferred tax asset, management must assess both positive and negative evidence with regard to the realizability of the tax losses represented by that asset. To the extent available, if sources of taxable income are insufficient to absorb tax losses, a valuation allowance is necessary. Sources of taxable income for this analysis include prior years’ tax returns, the expected reversals of taxable temporary differences between book and tax income, prudent and feasible tax-planning strategies, and future taxable income. The deferred income tax asset related to the allowance for loan losses will be realized when actual charge-offs are made against the allowance. Based on the availability of loss carry-backs and projected taxable income during the periods for which loss carry-forwards are available, management believes it is more likely than not the Corporation will realize the deferred tax asset. The Corporation continues to monitor the deferred tax asset on a quarterly basis for a valuation allowance. The future realization of these tax benefits primarily hinges on adequate future earnings to utilize the tax benefit. Prospective earnings or losses, tax law changes or capital changes could prompt the Corporation to reevaluate the assumptions which may be used to establish a valuation allowance. The Corporation files income tax returns for the United States and California jurisdictions. The Internal Revenue Service has audited the Bank’s income tax returns through 1996 and the California Franchise Tax Board has audited the Bank through 1990. Also, the Internal Revenue Service completed a review of the Corporation’s income tax returns for fiscal 2006 and 2007; and the California Franchise Tax Board completed a review of the Corporation’s income tax returns for fiscal 2009 and 2010. Fiscal years of 2014 and forward remain subject to federal examination, while the California state tax returns for fiscal years 2013 and forward are subject to examination by state taxing authorities.
Bank owned life insurance (BOLI) | C 715-60-35, "Accounting for Deferred Compensation and Postretirement Benefit Aspects of Endorsement Split-Dollar Life Insurance Arrangements," requires an employer to recognize obligations associated with endorsement split-dollar life insurance arrangements that extend into the participant's post-employment benefit cost for the continuing life insurance or based on the future death benefit depending on the contractual terms of the underlying agreement. The Corporation adopted ASC 715-60-35 using the latter option, i.e., based on the future death benefit. The Bank purchases BOLI policies on the lives of certain executive officers while they are employed by the Bank and is the owner and beneficiary of the policies. The Bank invests in BOLI to provide an efficient form of funding for long-term retirement and other employee benefits costs. The Bank records these BOLI policies within prepaid expenses and other assets in the Consolidated Statements of Financial Condition at each policy’s respective cash surrender value, with changes recorded in other non-interest income and salaries and employee benefits expense in the Consolidated Statements of Operations.
Cash dividend and stock repurchases | ash dividend A declaration or payment of dividends is at the discretion of the Corporation’s Board of Directors, who take into account the Corporation’s financial condition, results of operations, tax considerations, capital requirements, industry standards, economic conditions and other factors, including the regulatory restrictions which affect the payment of dividends by the Bank to the Corporation. Under Delaware law, dividends may be paid either out of surplus or, if there is no surplus, out of net profits for the current fiscal year and/or the preceding fiscal year in which the dividend is declared. For additional information, see Note 22 of the Notes to Consolidated Financial Statements regarding the subsequent event related to the cash dividend. Stock repurchases The Corporation repurchases its common stock consistent with Board-approved stock repurchase plans. During fiscal 2018, the Corporation repurchased 383,585 shares with an average cost of $19.00 per share, all of which were purchased under the June 2017 stock repurchase plan.
Earnings per common share (EPS) | arnings per common share (“EPS”) Basic EPS represents net income divided by the weighted average common shares outstanding during the period excluding any potential dilutive effects. Diluted EPS gives effect to any potential issuance of common stock that would have caused basic EPS to be lower as if the issuance had already occurred. Accordingly, diluted EPS reflects an increase in the weighted average shares outstanding as a result of the assumed exercise of stock options and the vesting of restricted stock. The computation of diluted EPS does not assume exercise of stock options and vesting of restricted stock that would have an anti-dilutive effect on EPS.
Stock-based compensation | tock-based compensation ASC 718, “Compensation – Stock Compensation,” requires companies to recognize in the statement of operations the grant-date fair value of stock options and other equity-based compensation issued to employees and directors. S
Employee Stock Ownership Plan (ESOP) | mployee Stock Ownership Plan ("ESOP") The Corporation recognizes compensation expense when the Bank contributes funds to the ESOP for the purchase of the Corporation’s common stock to be allocated to the ESOP participants. Since the contributions are discretionary, the benefits payable under the ESOP cannot be estimated.
Restricted stock | estricted stock The Corporation recognizes compensation expense over the vesting period of the shares awarded, equal to the fair value of the shares at the award date.
Post retirement benefits | ost retirement benefits The estimated obligation for post retirement health care and life insurance benefits is determined based on an actuarial computation of the cost of current and future benefits for the eligible (grandfathered) retirees and employees. The post retirement benefit liability is included in accounts payable, accrued interest and other liabilities in the Consolidated Statements of Financial Condition. Effective July 1, 2003, the Corporation discontinued the post retirement health care and life insurance benefits to any employee not previously qualified (grandfathered) for these benefits.
Comprehensive income (loss) | omprehensive income ASC 220, “Comprehensive Income,” requires that realized revenue, expenses, gains and losses be included in net income (loss). Unrealized gains (losses) on available for sale securities and interest-only strips are reported as a separate component of the stockholders’ equity section of the Consolidated Statements of Financial Condition and the change in the unrealized gains (losses) are reported on the Consolidated Statements of Comprehensive Income and Consolidated Statements of Stockholders' Equity.
Impaired financing receivables | Non-performing loans are charged-off to their fair market values in the period the loans, or portion thereof, are deemed uncollectible, generally after the loan becomes 150 days delinquent for real estate secured first trust deed loans and 120 days delinquent for commercial business or real estate secured second trust deed loans. For loans that were modified from their original terms, were re-underwritten and identified in the Corporation's asset quality reports as restructured loans, the charge-off occurs when the loan becomes 90 days delinquent; and where borrowers file bankruptcy, the charge-off occurs when the loan becomes 60 days delinquent. The amount of the charge-off is determined by comparing the loan balance to the estimated fair value of the underlying collateral, less disposition costs, with the loan balance in excess of the estimated fair value charged-off against the allowance for loan losses. The allowance for loan losses for non-performing loans is determined by applying ASC 310, “Receivables.” For restructured loans that are less than 90 days delinquent, the allowance for loan losses are segregated into (a) individually evaluated allowances for those loans with applicable discounted cash flow calculations still in their restructuring period, classified lower than pass, and containing an embedded loss component or (b) collectively evaluated allowances based on the aggregated pooling method. For non-performing loans less than 60 days delinquent where the borrower has filed bankruptcy, the collectively evaluated allowances are assigned based on the aggregated pooling method. For non-performing commercial real estate loans, individually evaluated allowances are calculated based on their fair values and if their fair values are higher than their loan balances, no allowances are required.
Off-balance sheet credit exposure | The Corporation 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 include commitments to extend credit in the form of originating loans or providing funds under existing lines of credit, loan sale commitments to third parties and option contracts. These instruments involve, to varying degrees, elements of credit and interest-rate risk in excess of the amount recognized in the accompanying Consolidated Statements of Financial Condition. The Corporation’s exposure to credit loss, in the event of non-performance by the counterparty to these financial instruments, is represented by the contractual amount of these instruments. The Corporation uses the same credit policies in entering into financial instruments with off-balance sheet risk as it does for on-balance sheet instruments. As of June 30, 2018 and 2017, the Corporation had commitments to extend credit (on loans to be held for investment and loans to be held for sale) of $66.3 million and $111.8 million, respectively.
