New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements Not Yet Adopted	IMPACT OF RECENT ACCOUNTING STANDARDS In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard, as modified and augmented by subsequently issued pronouncements (ASUs 2016-08, 2016-10, 2016-12, 2016-20, 2017-05, 2017-13 and 2017-14) is effective for annual periods beginning after December 15, 2017 (April 1, 2018 for the Company), and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a modified retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company has completed its review of the impact of this guidance and concluded that (1) a substantial majority of the Company's revenue is comprised of interest income on financial assets, which is explicitly excluded from the scope of ASU 2014-09 and (2) based on our understanding of the standard and subsequent modification and the nature of our non-interest revenue, many elements of non-interest income will be unaffected. The Company identified the non-interest income streams that are contractually based and has adopted this ASU on a modified retrospective approach. Since the new guidance does not have a material impact to the Company's consolidated financial statements, a cumulative effect adjustment to opening retained earnings was not deemed necessary. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendments (1) require equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (2) simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (3) eliminate the requirement to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (4) require public business entities to use an exit price notion when measuring the fair value of financial instruments for disclosure purposes, (5) require an entity to separately present in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (6) require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements, and (7) clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets. ASU No. 2016-01 is effective for fiscal years beginning after December 15, 2017 (for the Company, the fiscal year ended March 31, 2019), including interim periods within those fiscal years. The adoption of this standard by public entities is permitted as of the beginning of the year of adoption for selected amendments, including the amendment related to unrealized gains and losses on equity securities, by a cumulative effect adjustment to the statement of financial condition. In February 2018, the FASB issued ASU No. 2018-03, "Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10)" to clarify certain aspects of the guidance issued in ASU 2016-01. The amendments in this update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. The Company completed its evaluation of the provisions of ASU 2016-01 and identified the equity investments that falls under ASU 2016-01. The Company adopted this ASU during the first quarter of fiscal year 2019 and the impact amounted to a cumulative effect adjustment of $721 thousand as a reclassification from accumulated other comprehensive loss to accumulated deficit. Additionally, all future unrealized gains and losses will be recognized in the Statements of Operations. See Note 6 "Investment Securities" for further information. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." From the lessee's perspective, the new standard establishes a right-of-use ("ROU") model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement for a lessee. From the lessor's perspective, the new standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing. If the lessor doesn't convey risks and rewards or control, an operating lease results. A modified retrospective transition approach is required for lessors for sales-type, direct financing, and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. ASU No. 2016-02, as augmented by ASU No. 2018-01, is effective for fiscal years beginning after December 15, 2018 (for the Company, he fiscal year ended March 31, 2020), including interim periods within those fiscal years. In July 2018, the FASB issued ASU No. 2018-10, "Codification Improvements to Topic 842, Leases," to clarify and correct unintended application of the guidance in ASU No. 2016-02. The amendments in this ASU affect aspects of the guidance and provide clarification to related topics such as 1) rate implicit in the lease; 2) reassessment of leases; 3) transition guidance; and 4) impairment of net investment in the lease. In July 2018, the FASB also issued ASU 2018-11, "Leases (Topic 842) Target Improvements," which provides guidance related to comparative reporting requirements for initial adoption. This amendment provides entities with another transition method, in addition to the modified retrospective approach, by allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company currently expects that upon adoption of ASU 2016-02, ROU assets and lease liabilities will be recognized in the consolidated balance sheet in amounts that will be material. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Loss," which updates the guidance on recognition and measurement of credit losses for financial assets. The new requirements, known as the current expected credit loss model ("CECL") will require entities to adopt an impairment model based on expected losses rather than incurred losses. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019 (for the Company, the fiscal year ending March 31, 2021), including interim periods within those fiscal years. The Company is currently evaluating the potential impact of the adoption of the new standard on its consolidated statements of financial condition and results of operations. In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments," a consensus of the FASB's Emerging Issues Task Force. The update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows, and provides guidance on how the following cash receipts and payments should be presented and classified in the statement of cash flows: debt prepayment or debt extinguishment costs, settlement of zero-coupon bonds, contingent consideration payments made after a business combination, settlements of insurance claims, settlements of corporate-owned and bank-owned life insurance policies, distributions received from equity method investees, and beneficial interests in securitization transactions. The ASU also clarifies when an entity should separate cash receipts and payments and classify them into more than one class of cash flows. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017 (for the Company, the fiscal year ending March 31, 2019), and interim periods within those fiscal years. The Company has evaluated the potential impact of the adoption of the new standard on its consolidated statement of cash flows and is generally unaffected by the update. The items defined in the ASU are not relevant to the Company's operations at this time. In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash," to require that a statement of cash flows explain the change during the period in restricted cash or restricted cash equivalents, in addition to changes in cash and cash equivalents. The update provides guidance that restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU No. 2016-18 is effective for fiscal years beginning after December 15, 2017 (for the Company, the fiscal year ending March 31, 2019), and interim periods within those fiscal years. The Company has completed its assessment of the impact of adopting of ASU 2016-18 and is generally unaffected by the update. The Company does not have restricted cash at this time. In March 2017, the FASB issued ASU No. 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities," which shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. The amendments are effective for fiscal years beginning after December 15, 2018 (for the Company, the fiscal year ending March 31, 2020), and interim periods within those fiscal years. Based on management's review of the securities in the Company's portfolio at September 30, 2018, the adoption of the standard is not expected to have a material impact on the Company's consolidated statements of financial condition and results of operations. In May 2017, the FASB issued ASU No. 2017-09, "Compensation - Stock Compensation (Topic 718), Scope of Modification Accounting," which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The new guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 (for the Company, the fiscal year ending March 31, 2019). The adoption of the standard does not have a material impact on the Company's consolidated statements of financial condition and results of operations. In February 2018, the FASB issued ASU No. 2018-02 "Income Statement - Reporting Comprehensive Income (Topic 220)," which allows a reclassification for stranded tax effects from accumulated other comprehensive income to retained earnings, to eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments addressed concerns regarding the guidance that requires deferred tax assets and liabilities to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting periods that include the enactment date. The amendments of this update are effective for fiscal years beginning after December 15, 2018 (for the Company, the fiscal year ending March 31, 2020), and interim periods within those fiscal years. Early adoption is permitted in any interim period for reporting periods for which financial statements have not yet been issued.
