Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 2 . Recent Accounting Pronouncements The pronouncements discussed below are not intended to be an all-inclusive list, but rather only those pronouncements that could potentially have a material impact on our financial position, results of operations or disclosures. Accounting Standards Adopted in the Period In February 2016, the FASB issued ASU 2016-02 “Leases.” ASU 2016-02 affects any entity that enters into a lease and is intended to increase the transparency and comparability of financial statements among organizations. The ASU requires, among other changes, a lessee to recognize on its balance sheet a lease asset and a lease liability for those leases longer than 12 months previously classified as operating leases. The lease asset would represent the right to use the underlying asset for the lease term and the lease liability would represent the discounted value of the required lease payments to the lessor. The ASU also requires entities to disclose key information about leasing arrangements. The Company currently leases eleven branches and two administrative offices. The Company adopted this standard and the related amendments (collectively "ASC 842") on July 1, 2019 and utilized the modified retrospective approach provided by ASU 2018-11, "Leases (Topic 842): Targeted Improvements," that allowed for a cumulative effect adjustment in the period of adoption. Under this method of adoption, the comparative information in the consolidated financial statements has not been revised and continues to be reported under the previously applicable lease accounting guidance (ASC 840). We also utilized the package of practical expedients permitted under the transition guidance which included the carry-forward of historical lease classification. The Company recorded a right to use asset totaling $11.9 million and lease liability totaling $12.0 million on the balance sheet for Company’s outstanding lease obligations on July 1, 2019. The right to use asset is disclosed within premises and equipment and the lease liability is disclosed within other liabilities on the balance sheet. In January 2017, the FASB issued ASU 2017-04 “Intangibles – Goodwill and Other (Topic 350).” In March 2017, the FASB issued ASU 2017-08 "Receivables - Non-Refundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The ASU requires premiums on callable debt securities to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The adoption of ASU 2017-08 on July 1, 2019 did not have a material impact on the Company’s consolidated financial statements. Future Application of Accounting Pronouncements Previously Issued In June 2016, the FASB issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 affects entities holding financial assets that are not accounted for at fair value through net income, including loans, debt securities, and other financial assets. The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected by recording an allowance for current expected credit losses. In October 2019, the FASB unanimously voted to delay the implementation of the standard for three years for certain companies, including small reporting companies (as defined by the SEC), non-SEC public companies and private companies. The Company currently qualifies as a small reporting company and is subject to the delayed implementation. Therefore, t he amendments in this update will be effective for the Company for the fiscal year beginning on July 1, 2023, including interim periods within that fiscal year. The Company is actively working through the provisions of the Update. Management has established a steering committee which is identifying the methodologies and the additional data requirements necessary to implement the Update and has engaged a third-party software service provider to assist in the Company's implementation. Management is currently evaluating the impact that ASU 2016-13 will have on the Company’s consolidated financial position, results of operations and disclosures.

The majority of unrealized losses are related to the Company’s U.S. Government and agency obligations and mortgage-backed securities. As of June 30, 2019, the Company’s securities portfolio consisted of $417.8 million in securities, of which 135 securities with a fair value of $229.2 million were in an unrealized loss There were no securities as of September 30, 2019 or June 30, 2019 for which the Company believes it is not probable that it will collect all amounts due according to the contractual terms of the security. Management believes the unrealized losses are primarily a result of changes in interest rates. The Company has determined that it does not intend to sell, or it is not more likely than not that it will be required to sell, its securities that are in an unrealized loss position prior to the recovery of its amortized cost basis. Therefore, the Company did not consider any securities to be other-than-temporarily impaired as of September 30, 2019 or June 30, 2019.

The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan. As of both September 30, 2019 and June 30, 2019, the Company had 14 loans classified as troubled debt restructurings totaling $4.1 million, including $3.1 million and $3.2 million, respectively, of loans still accruing. The Company has allocated $129,000 and $135,000, respectively, of specific reserves to customers whose loan terms have been modified in troubled debt restructurings as of September 30, 2019 and June 30, 2019. The Company has not committed to lend additional amounts to customers with outstanding loans that are classified as troubled debt restructurings. The Company did not modify any loans in troubled debt restructurings during the three months three months The Company had one troubled debt restructuring, a residential mortgage with a carrying amount of $370,000, default in the three months ended September 30, 2019 that was modified in the twelve months prior to default. This default resulted in no charge-off nor an increase to the allowance for loan losses. The Company had no troubled debt restructurings for which there was a payment default in the three months ended September 30, 2018, that were modified in the twelve months prior to default. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company utilized the same grading process for acquired loans as it does for originated loans. The Company uses the following definitions for risk ratings: Special Mention – Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date. Substandard – Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above-described process and loans in groups of homogenous loans are considered to be pass rated loans. These loans are monitored based on delinquency and performance. Based on the most recent analysis performed, the risk category of loans by portfolio segment is as follows (in thousands): September 30, 2019 Pass Special Mention Substandard Total Originated: Residential $ 218,193 $ 396 $ 1,250 $ 219,839 Commercial 674,956 337 3,110 678,403 Construction 18,830 - - 18,830 Commercial loans 118,113 4,070 3,563 125,746 Home equity lines of credit 27,344 72 352 27,768 Consumer and overdrafts 422 - - 422 Total originated 1,057,858 4,875 8,275 1,071,008 Acquired: Residential 43,056 206 1,150 44,412 Commercial 42,962 3,496 1,454 47,912 Commercial loans 180 - - 180 Home equity lines of credit 3,285 67 383 3,735 Consumer and overdrafts 15 - - 15 Total acquired 89,498 3,769 2,987 96,254 Total $ 1,147,356 $ 8,644 $ 11,262 $ 1,167,262 June 30, 2019 Pass Special Mention Substandard Total Originated: Residential $ 216,438 $ 1,071 $ 547 $ 218,056 Commercial 600,216 339 120 600,675 Construction 13,231 - - 13,231 Commercial loans 123,361 6,423 3,652 133,436 Home equity lines of credit 28,996 67 360 29,423 Consumer and overdrafts 349 - - 349 Total originated 982,591 7,900 4,679 995,170 Acquired: Residential 44,959 211 1,941 47,111 Commercial 45,726 3,537 1,458 50,721 Commercial loans 178 - - 178 Home equity lines of credit 3,331 68 382 3,781 Consumer and overdrafts 16 - - 16 Total acquired 94,210 3,816 3,781 101,807 Total $ 1,076,801 $ 11,716 $ 8,460 $ 1,096,977 Purchased Credit Impaired Loans The Company has acquired loans for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected.

Employee Stock Ownership Plan On January 1, 2017, the Company established an Employee Stock Ownership Plan (“ESOP”) to provide eligible employees the opportunity to own Company stock. The ESOP is a tax-qualified retirement plan for the benefit of Company employees. On April 20, 2017, the Company granted a loan to the ESOP for the purchase of 1,453,209 shares of the Company’s common stock at a price of $10.00 per share. The loan obtained by the ESOP from the Company to purchase the common stock is payable annually over 15 years at a rate per annum equal to the Prime Rate, reset annually on January 1st (5.50% for 2019). Loan payments are principally funded by cash contributions from the Bank. The loan is secured by the shares purchased, which are held in a suspense account for allocation among participants as the loan is repaid. The balance of the ESOP loan at September 30, 2019 was $12.6 million. Contributions are allocated to eligible participants on the basis of compensation, subject to federal tax limits. The number of shares committed to be released annually is 96,881 through 2032. Dividends on allocated shares increase participant accounts and are used to purchase additional shares of stock. Participants receive the shares at the end of employment. Shares held by the ESOP include the following (dollars in thousands): September 30, 2019 June 30, 2019 Allocated to participants 258,852 234,059 Unearned 1,186,991 1,211,410 Total ESOP shares 1,445,843 1,445,469 Fair value of unearned shares $ 23,728 $ 24,531 Total compensation expense recognized in connection with the ESOP for the three

There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as general classification of such instruments pursuant to the valuation hierarchy, is set forth below. While management believes the Company’s valuation methodologies are appropriate and consistent with other financial institutions, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Investment Securities Impaired Loans Foreclosed Real Estate Foreclosed properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Credit Department, as well as a third-party specialist, where deemed appropriate, reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Once appraisals are considered appropriate, management discounts the appraised value for estimated selling costs, such as legal, broker, and property maintenance and insurance costs. The most recent analysis performed indicated discount rates ranging between 10% and 20% should be applied to properties with appraisals performed.

Regulatory Capital The following is a summary of the Bank’s actual capital amounts and ratios as of September 30, 2019 and June 30, 2019, compared to the required ratios for minimum capital adequacy and for classification as well capitalized (dollars in thousands). As a result of the Economic Growth, Regulatory Relief, and Consumer Protection Act passed by Congress in 2018, the Company is no longer subject to consolidated capital requirements, as the Company’s total consolidated assets do not exceed $3 billion.

Management believes that as of September 30, 2019 and June 30, 2019, the Bank met all capital adequacy requirements to which it was subject, including the capital conservation buffer of 2.5%, as of September 30, 2019 and June 30, 2019, respectively. Further, the most recent FDIC notification categorized the Bank as a well-capitalized institution under the prompt corrective action regulations. There have been no conditions or events since that notification that management believes have changed the Bank’s capital classification.

Earnings Per Share [Abstract]
Earnings Per Share	Note 9. Earnings Per Share Basic EPS is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated in a similar matter, except that the denominator includes the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method. Dilutive financial instruments include stock options and unvested restricted stock. The following table provides factors used in the earnings per share computation for the three months ended September 30, 2019 and 2018. Three Months Ended September 30, 2019 2018 (amounts in thousands, except share and per share data) Net income applicable to common stock $ 2,829 $ 2,329 Average number of common shares outstanding 17,178,824 18,165,110 Less: Average unallocated ESOP shares (1,199,062 ) (1,296,010 ) Average number of common shares outstanding used to calculate basic earnings per common share 15,979,762 16,869,100 Effect of equity-based awards 102,514 - Average number of common shares outstanding used to calculate diluted earnings per common share 16,082,276 16,869,100 Earnings per common share: Basic $ 0.18 $ 0.14 Diluted $ 0.18 $ 0.14 Stock options for 1,339,293 shares of common stock were not considered in computing diluted earnings per common share for the three months ended September 30, 2019 because they were antidilutive. There were no potentially dilutive common stock equivalents outstanding during the three months ended September 30, 2018.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Note 10. Derivatives and Hedging Derivatives not designated as hedges may be used to manage the Company’s exposure to interest rate movements or to provide service to customers. The Company executes interest rate swaps with commercial lending customers to facilitate their respective risk management strategies. These interest rate swaps with customers are simultaneously offset by interest rate swaps that the Company executes with a third party in order to minimize the net risk exposure resulting from such transactions. These interest rate swap agreements do not qualify for hedge accounting treatment, and therefore changes in fair value are reported in current period earnings. The following table presents summary information about the interest rate swaps as of September 30, 2019 and June 30, 2019.

Revenue From Contract With Customer [Abstract]
Revenue From Contracts With Customers	Note 11. Revenue From Contracts With Customers In accordance with ASU 2014-09, revenue is recognized when a customer obtains control of promised services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these services. The Company applies the following five steps to properly recognize revenue: 1. Identify the contract with a customer 2. Identify the performance obligations in the contract 3. Determine the transaction price 4. Allocate the transaction price to performance obligations in the contract 5. Recognize revenue when (or as) the Company satisfies a performance obligation The Company’s revenue streams that are within the scope of the accounting standard are: (1) fees and service charges on deposit accounts (including interchange fees), which, are included on the Consolidated Statements of Operations as “Fees and service charges” and (2) gains on the sale of foreclosed real estate. For the three months ended September 30, 2019 and 2018, fees and services charges totaled $402,000 and $418,000, respectively, of which and $372,000 and $392,000, respectively, were revenue streams within the scope of the accounting standard. Fees and Service Charges on Deposit Accounts . The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payments, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of the month, representing the period over which the Company satisfied the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. For the September 30, 2019 and 2018, fees and service charges on deposit accounts were $255,000 and $287,000, respectively. Interchange Income . The Company earns interchange fees from debit cardholder transactions conducted through various payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. For the three months ended September 30, 2019 and 2018, interchange income was $117,000 and $105,000, respectively. Gain/Losses on Sales of Foreclosed Real Estate . The Company records a gain or loss from the sale of foreclosed real estate when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of foreclosed real estate to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the foreclosed real estate asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. For the three months ended September 30, 2019, the Company recorded $47,000 gain on sale of foreclosed real estate, compared to no gain on sale of foreclosed real estate recorded in the prior year.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation	Note 12. Stock-Based Compensation On October 24, 2018, the Company’s shareholders approved the PCSB Financial Corporation 2018 Equity Incentive Plan (the “Plan”), which permits the grant of stock options and restricted stock and/or restricted stock units. The total number of shares that may be granted under the Plan is 2,543,115, of which 1,816,511 shares may be granted as stock options and 726,604 shares may be granted as restricted stock and restricted stock units. Total compensation cost that has been charged against income for the Plan was $830,000 for the three months ended September 30, 2019. No compensation cost was incurred for the three months ended September 30, 2018. Restricted Stock Awards (“RSAs”) RSAs provide for the issuance of shares to both employees and non-employee directors. These awards generally vest over a 5-year period, with 20% vesting each year on the anniversary of the award. All awards were made at the fair value of common stock on the grant date. Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at grant date. The fair value of the stock was determined to be the closing price of the stock on the NASDAQ exchange. Total shares available for grant under the Plan are 726,604, of which 547,185 shares were issued as of September 30, 2019. The following table presents a summary of RSA activity during the period ended September 30, 2019. Number of Shares Weighted-Average Grant Date Fair Value Unvested granted shares outstanding at July 1, 2019 547,185 $ 19.02 Shares granted - - Shares vested - - Shares forfeited - - Unvested granted shares at September 30, 2019 547,185 $ 19.02 As of September 30, 2019, there was $8.5 million of total unrecognized compensation cost related to nonvested shares granted under the Plan. The cost is expected to be recognized over a weighted-average period of 4.1 years. Stock Option Awards Stock options awarded to employees under the Plan are considered incentive stock options (ISOs), up to applicable limits. Option awards are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant. Those issued to non-employee directors, as well as those exceeding ISO limitations, are considered non-qualified stock options (NQSOs). Options generally vest over a 5-year period, with 20% vesting each year on the anniversary of the award, however may not vest more rapidly than over a three-year period, and have a contractual term of 10 years. The Company has a policy of using shares held as a treasury stock to satisfy share option exercises. Currently, the Company has a sufficient number of treasury shares to satisfy the current level of exercisable share options. The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatilities of a peer group of publicly-traded financial institutions. The expected term of options granted is based on the simplified “mid-point” approach which utilizes the weighted average vesting period and contractual term. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. As of September 30, 2019, there was $5.1 million of total unrecognized compensation cost related to non-vested stock options granted under the Plan. The cost is expected to be recognized over a weighted-average period of 4.1 years. Total shares available for grant under the Plan are 1,816,511, of which 1,339,293 shares were issued as of September 30, 2019. The following table presents a summary of activity related to stock options granted under the Plan, and changes during the period then ended: Number of Options Weighted- Average Exercise Price Weighted- Average Remaining Contractual Years Aggregate Intrinsic Value (dollars in thousands, except share and per share data) Options outstanding at July 1, 2019 1,339,293 $ 19.04 Options granted - - Options expired - - Options exercised - - Options outstanding at September 30, 2019 1,339,293 $ 19.04 9.1 $ 1,277 Exercisable at September 30, 2019 - $ - - $ -

Leases [Abstract]
Leases	Note 13. Leases Effective July 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842). As of September 30, 2019, the Company leases real estate for eleven branch offices and two administrative offices, including its corporate headquarters, under various operating lease agreements. The Company’s leases have maturities which range from 2020 to 2041, some of which include lessee options to extend the lease term. The weighted average remaining life of the lease term for these leases was 10.1 years as of September 30, 2019. The operating lease asset and lease liability are determined at the commencement date of the lease based on the present value of the lease payments. As most of our leases do not provide an implicit rate, the Company used its incremental borrowing rate, the rate of interest to borrow on a collateralized basis for a similar term, at the lease commencement date. The Company utilized a weighted average discount rate of 2.37% in determining the lease liability as of September 30, 2019. The Company made a policy election to exclude the recognition requirements of ASU 2016-02 to short-term leases, those leases with original terms of 12 months or less. Short-term lease payments are recognized in the income statement on a straight-line basis over the lease term. The Company had no short-term lease cost for the three months ended September 30, 2019. Certain leases may include one or more options to renew. The exercise of lease renewal options is typically at the Company’s discretion and are included in the operating lease liability if it is reasonably certain that the renewal option will be exercised. Certain real estate leases may contain lease and non-lease components, such as common area maintenance charges, real estate taxes, and insurance, which are generally accounted for separately and are not included in the measurement of the lease liability since they are generally able to be segregated. The Company does not sublease any of its leased properties. There were no sale and leaseback transactions, leveraged leases or lease transactions with related parties during the three months ended September 30, 2019. Total operating lease costs were $473,000 for the three months ended September 30, 2019. The right-of-use asset, included in premises and equipment, net, was $12.3 million as of September 30, 2019 and the corresponding lease liability, included in other liabilities was $12.6 million as of September 30, 2019.

Use of Estimates	Use of Estimates
Recent Accounting Pronouncements	The pronouncements discussed below are not intended to be an all-inclusive list, but rather only those pronouncements that could potentially have a material impact on our financial position, results of operations or disclosures. Accounting Standards Adopted in the Period In February 2016, the FASB issued ASU 2016-02 “Leases.” ASU 2016-02 affects any entity that enters into a lease and is intended to increase the transparency and comparability of financial statements among organizations. The ASU requires, among other changes, a lessee to recognize on its balance sheet a lease asset and a lease liability for those leases longer than 12 months previously classified as operating leases. The lease asset would represent the right to use the underlying asset for the lease term and the lease liability would represent the discounted value of the required lease payments to the lessor. The ASU also requires entities to disclose key information about leasing arrangements. The Company currently leases eleven branches and two administrative offices. The Company adopted this standard and the related amendments (collectively "ASC 842") on July 1, 2019 and utilized the modified retrospective approach provided by ASU 2018-11, "Leases (Topic 842): Targeted Improvements," that allowed for a cumulative effect adjustment in the period of adoption. Under this method of adoption, the comparative information in the consolidated financial statements has not been revised and continues to be reported under the previously applicable lease accounting guidance (ASC 840). We also utilized the package of practical expedients permitted under the transition guidance which included the carry-forward of historical lease classification. The Company recorded a right to use asset totaling $11.9 million and lease liability totaling $12.0 million on the balance sheet for Company’s outstanding lease obligations on July 1, 2019. The right to use asset is disclosed within premises and equipment and the lease liability is disclosed within other liabilities on the balance sheet. In January 2017, the FASB issued ASU 2017-04 “Intangibles – Goodwill and Other (Topic 350).” In March 2017, the FASB issued ASU 2017-08 "Receivables - Non-Refundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The ASU requires premiums on callable debt securities to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The adoption of ASU 2017-08 on July 1, 2019 did not have a material impact on the Company’s consolidated financial statements. Future Application of Accounting Pronouncements Previously Issued In June 2016, the FASB issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 affects entities holding financial assets that are not accounted for at fair value through net income, including loans, debt securities, and other financial assets. The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected by recording an allowance for current expected credit losses. In October 2019, the FASB unanimously voted to delay the implementation of the standard for three years for certain companies, including small reporting companies (as defined by the SEC), non-SEC public companies and private companies. The Company currently qualifies as a small reporting company and is subject to the delayed implementation. Therefore, t he amendments in this update will be effective for the Company for the fiscal year beginning on July 1, 2023, including interim periods within that fiscal year. The Company is actively working through the provisions of the Update. Management has established a steering committee which is identifying the methodologies and the additional data requirements necessary to implement the Update and has engaged a third-party software service provider to assist in the Company's implementation. Management is currently evaluating the impact that ASU 2016-13 will have on the Company’s consolidated financial position, results of operations and disclosures.
