SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Sep. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on the Quarterly Report on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles (GAAP) are not included herein. These interim statements should be read in conjunction with the consolidated financial statements and notes included in the Annual Report on Form 10-K for the year ended December 31, 2018 filed by the Company with the SEC. The December 31, 2018 consolidated statements of financial condition presented herein has been derived from the audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC, but does not include all of the disclosures required by GAAP for complete financial statements.
Reclassification	In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented.
Principles of Consolidation	Principles of Consolidation: The accompanying unaudited consolidated financial statements include the accounts of the Company and its consolidated subsidiaries as of September 30, 2019 and December 31, 2018 and for the three and nine months ended September 30, 2019 and 2018. Significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its then wholly-owned subsidiaries.
Accounting Pronouncements	Adopted Accounting Pronouncements: During the nine months ended September 30, 2019, the following pronouncements applicable to the Company were adopted: In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) 2016-02 Topic 842, “Leases” which increases transparency and comparability among organizations by requiring the recognition of right of use (ROU) assets and lease liabilities on the balance sheet. Most prominent among the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted Topic 842 and related updates effective January 1, 2019 and used the effective date as the date of initial application, and therefore, periods prior to January 1, 2019 were not restated. The Company elected the package of practical expedients, which permits us not to reassess prior conclusions about lease identifications, lease classification and initial direct costs under the new standard. The Company did not elect to apply the hindsight practical expedient pertaining to using hindsight knowledge as of the effective date when determining lease terms and impairment. The Company also has elected the short-term lease recognition exemption (leases with terms 12 months or less) for all leases that qualify, and thus will not recognize ROU assets or lease liabilities for those leases. In addition, the Company elected the practical expedient to not separate lease and non-lease components for all of our leases. Upon adoption, the Company recognized on its consolidated balance sheet ROU assets of approximately $23.3 million (inclusive of an adjustment to remove the Company's existing deferred rent liability of approximately $1.4 million) with a corresponding operating lease liability of approximately $24.7 million. The standard did not have an impact on our consolidated statements of operations. In addition, the Company's accounting for finance leases remained substantially unchanged. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment," which amended ASC 350 "Intangibles-Goodwill and Other." The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company has early adopted this guidance prospectively as of August 31, 2019, and the adoption did not have a material impact on our financial statements. Significant Accounting Policies: The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. The Company has not made any significant changes in its critical accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC, except for the accounting for leases as described below. Leases. The Company determines if an arrangement is a lease at inception. The Company’s operating lease agreements are primarily for real estate space and are included within right of use (ROU) assets and lease liabilities on the September 30, 2019 consolidated balance sheet. The ROU asset is based on the operating lease liabilities adjusted for any prepaid or deferred rent. The Company has elected not to recognize on its consolidated balance sheet leases with terms of one-year or less. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment, at lease commencement date in determining the present value of lease payments. Many of the Company’s lessee agreements include options to extend the lease, which the Company does not include in its minimum lease terms unless they are reasonably certain to be exercised. The Company elected the practical expedient to combine its lease and related nonlease components for the Company’s building leases. Rental expense for lease payments related to operating leases is recognized on a straight-line basis over the lease term
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the consolidated financial statements and disclosures provided, and actual results could differ. The allowance for loan losses (ALLL), reserve for loss on repurchased loans, reserve for unfunded loan commitments, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking and other derivatives, Hypothetical Liquidation at Book Value (HLBV) of investments in alternative energy partnerships, and the fair value measurement of financial instruments are particularly subject to change and such change could have a material effect on the consolidated financial statements.
Discontinued Operations	Discontinued Operations: During the three months ended March 31, 2017, the Company completed the sale of its Banc Home Loans division, which largely represented the Company's Mortgage Banking segment. In accordance with Accounting Standards Codification (ASC) 205-20, the Company determined that the sale of the Banc Home Loans division and certain other mortgage banking related assets and liabilities that would be sold or settled separately within one year met the criteria to be classified as a discontinued operation and the related operating results and financial condition have been presented as discontinued operations on the consolidated financial statements. See Note 2 for additional information. Unless otherwise indicated, information included in these notes to the consolidated financial statements is presented on a consolidated operations basis, which includes results from both continuing and discontinued operations, as of December 31, 2018 and for the three and nine months ended September 30, 2018.
Restructuring Expense	Restructuring Expense: During the three and nine months ended September 30, 2019, the Company continued to implement its strategic objective to de-emphasize the production of low margin loan products through its exit from the third-party mortgage origination ("TPMO") and brokered single family lending business.
