Accounting Policies [Abstract]
BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 — BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES CIT Group Inc., together with its subsidiaries (collectively "we", "our", "CIT" or the "Company"), is a bank holding company ("BHC") and a financial holding company ("FHC"). CIT was formed in 1908 and provides financing, leasing and advisory services principally to middle-market companies in a wide variety of industries, primarily in North America. CIT also provides banking and related services to commercial and individual customers through its banking subsidiary, CIT Bank, N.A. ("CIT Bank" or the "Bank"), which includes 69 branches located in Southern California and its online bank, bankoncit.com. CIT is regulated by the Board of Governors of the Federal Reserve System ("FRB") and the Federal Reserve Bank of New York ("FRBNY") under the U.S. Bank Holding Company Act of 1956, as amended. CIT Bank is regulated by the Office of the Comptroller of the Currency of the U.S. Department of the Treasury ("OCC"). BASIS OF PRESENTATION Basis of Financial Information These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q for interim financial information and accordingly do not include all information and note disclosures required by generally accepted accounting principles in the United States of America (“GAAP”) for complete financial statements. The financial statements in this Form 10-Q, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of CIT’s financial position, results of operations and cash flows in accordance with GAAP. These consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2017 ("2017 Form 10-K"). The accounting and financial reporting policies of CIT conform to GAAP and the preparation of the consolidated financial statements requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates and assumptions. Some of the more significant estimates include: allowance for loan losses, loan impairment, fair value determination, lease residual values, liabilities for uncertain tax positions, realizability of deferred tax assets, purchase accounting adjustments, indemnification assets, goodwill, intangible assets, and contingent liabilities, including amounts associated with discontinued operations. Additionally where applicable, the policies conform to accounting and reporting guidelines prescribed by bank regulatory authorities. Principles of Consolidation The accompanying consolidated financial statements include financial information related to CIT and its majority-owned subsidiaries and those VIEs where the Company is the primary beneficiary. In preparing the consolidated financial statements, all significant intercompany accounts and transactions have been eliminated. Assets held in an agency or fiduciary capacity are not included in the consolidated financial statements. The current period’s results of operations do not necessarily indicate the results that may be expected for any other interim period or for the full year as a whole. Discontinued Operations Discontinued Operations as of September 30, 2018 and December 31, 2017 included assets and liabilities of (i) the Business Air business and (ii) the Financial Freedom business. Income from discontinued operations reflects the activities of the Business Air and Financial Freedom businesses for the quarter and nine months ended September 30, 2018 and 2017, and Commercial Air (a component of Aerospace) for the nine months ended September 30, 2017. We completed the sale of our Commercial Air business on April 4, 2017. The Financial Freedom business, a former division of CIT Bank that serviced reverse mortgage loans, was acquired in conjunction with the OneWest Transaction in 2015 and was sold on May 31, 2018. The sale included all the operations, mortgage servicing rights and related servicing assets and liabilities, although certain assets and liabilities of the Financial Freedom business were still held by CIT Bank at September 30, 2018 and will continue to be held until the required investor consent is received to qualify for sale treatment. See further discussion in Note 2 — Discontinued Operations. reported in continuing operations, and which was serviced by the Financial Freedom business. ee further discussion in Note 3 — Loans SIGNIFICANT ACCOUNTING POLICIES Significant accounting policies are included in the Company's 2017 Form 10-K. Effective January 1, 2018, CIT changed its accounting policy for revenue recognition resulting from the adoption of Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers . Other Newly Adopted Accounting Standards Revenue Recognition On January 1, 2018, CIT adopted ASU 2014-09, Revenue Recognition - Revenue from Contracts with Customers (ASC 606) "Interest Income" and "Rental Income on Operating Leases", CIT's two largest revenue items, are out of scope of the new guidance, as are many other revenues relating to other financial assets and liabilities, including loans, leases, securities, and derivatives. As a result, the implementation of the new guidance was limited to certain revenue streams within Non-Interest Income, including some immaterial bank related fees and gains or losses related to the sale and disposition of leased equipment and OREO, which is accounted for under ASC 610-20, Gains and Losses From the Derecognition of Nonfinancial Assets, CIT evaluated its in-scope revenue streams under the five-step model and concluded that ASU 2014-09 did not materially impact the current practice of revenue recognition as ASC 606 is consistent with the current accounting policy being applied by the Company for these revenues. Therefore, no change in the timing or amount of income recognized was identified. CIT also determined that costs incurred to obtain or fulfill contracts and financing components relating to in-scope revenue streams were immaterial to the Company. Non-interest revenue, including amounts related to the sale and disposition of leased equipment and OREO, is recognized at an amount reflecting the consideration received, or expected to be received, when control of goods or services is transferred, which generally occurs when services are provided or control of leased equipment or OREO is liquidated. ASU 2014-09 was adopted using the modified retrospective transition method. CIT elected to apply this guidance only to contracts that were not completed at the date of the initial application. The adoption did not have a significant impact on CIT’s financial statements or disclosures. No adjustment to the opening balance of retained earnings was necessary. Interest income on held for investment ("HFI") loans is recognized using the effective interest method or on a basis approximating a level rate of return over the life of the asset. Interest income includes components of accretion of the fair value discount on loans and lease receivables recorded in connection with Purchase Accounting Adjustments (“PAA”), which are accreted using the effective interest method as a yield adjustment over the remaining contractual term of the loan and recorded in interest income. If the loan is subsequently classified as assets held for sale ("AHFS"), accretion (amortization) of the discount (premium) will cease. Rental revenue on operating leases is recognized on a straight line basis over the lease term and is included in Non-interest Income. Intangible assets related to acquisitions completed by the Company and Fresh Start Accounting (“FSA”) adjustments that were applied as of December 31, 2009 (the Convenience Date), were recorded to adjust the carrying value of above or below market operating lease contracts to their fair value. The FSA adjustments (net) are amortized into rental income on a straight line basis over the remaining term of the respective lease. The recognition of interest income (including accretion) on commercial loans (exclusive of small ticket commercial loans) is suspended and an account is placed on non-accrual status when, in the opinion of management, full collection of all principal and interest due is doubtful. All future interest accruals, as well as amortization of deferred fees, costs, purchase premiums or discounts are suspended. To the extent the estimated cash flows, including fair value of collateral, does not satisfy both the principal and accrued interest outstanding, accrued but uncollected interest at the date an account is placed on non-accrual status is reversed and charged against interest income. Subsequent interest received is applied to the outstanding principal balance until such time as the account is collected, charged-off or returned to accrual status. Loans that are on cash basis nonaccrual do not accrue interest income; however, payments designated by the borrower as interest payments may be recorded as interest income. To qualify for this treatment, the remaining recorded investment in the loan must be deemed fully collectable. The recognition of interest income (including accretion) on consumer mortgages and small ticket commercial loans and lease receivables is suspended and all previously accrued but uncollected revenue is reversed, when payment of principal and/or interest is contractually delinquent for 90 days or more. Accounts, including accounts that have been modified, are returned to accrual status when, in the opinion of management, collection of remaining principal and interest is reasonably assured, and there is a sustained period of repayment performance for a minimum of six months. The recognition of interest income on reverse mortgages is suspended upon the latter of the foreclosure sale date or date on which marketable title has been acquired (i.e., property becomes OREO). The Company periodically modifies the terms of a loan in response to borrowers’ financial difficulties. These modifications may include interest rate changes, principal forgiveness or payment deferments. Loans that are modified, where a concession has been made to the borrower, are accounted for as Troubled Debt Restructurings (“TDRs”). TDRs are generally placed on nonaccrual upon their restructuring and remain on non-accrual until, in the opinion of management, collection of remaining principal and interest is reasonably assured, and upon collection of six consecutive scheduled payments. Purchased credit impaired ("PCI") loans in pools that the Company may modify as TDRs are not within the scope of the accounting guidance for TDRs. Other Newly Adopted Accounting Standards The following pronouncements were issued by the Financial Accounting Standards Board (“FASB”) and adopted by CIT as of January 1, 2018. Refer to Note 1 - Business and Summary of Significant Accounting Policies on Form 10-Q for the quarter ended March 31, 2018 for a detailed description of these pronouncements: • ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. • ASU 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10). • ASU 2016-16, Income Taxes (Topic 740): Intra - Entity Transfers of Assets Other Than Inventory • ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments • ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cas • ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business • ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost • ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting • ASU 2018-02, Income Statement Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The following pronouncements were issued by FASB and adopted by CIT as of July 1, 2018.

As part of the Financial Freedom Transaction, the sale of the Financial Freedom business included all the operations, mortgage servicing rights and related servicing assets and liabilities. During the second quarter of 2018, CIT recognized a net pre-tax loss on disposal of the Financial Freedom business of $22 million in discontinued operations primarily related to reserves and transaction costs. CIT has agreed to indemnify the purchaser for potential loan defects and servicing deficiencies related to the transferred servicing rights, both of which are capped and subject to time limitations. See Note 1 – Business and Summary of Significant Accounting Policies for a description of the Financial Freedom Transaction. At September 30, 2018, certain assets and liabilities of the Financial Freedom business were still held by CIT Bank after the sale, and will continue to be held until the required investor consent is received to qualify for sale treatment, although the economic benefit and risk of the business has been transferred to the buyer. At September 30, 2018, assets of discontinued operations primarily included Home Equity Conversion Mortgage ("HECM") loans. Liabilities included reverse mortgage servicing liabilities, secured borrowings and contingent liabilities. As a mortgage servicer of residential reverse mortgage loans prior to the sale of Financial Freedom, the Company was exposed to contingent liabilities for breaches of servicer obligations as set forth in industry regulations established by the Department of Housing and Urban Development (“HUD”) and the Federal Housing Administration (“FHA”) and in servicing agreements with the applicable counterparties, such as third party investors. Under these agreements, the servicer may be liable for failure to perform its servicing obligations, which could include fees imposed for failure to comply with foreclosure timeframe requirements established by servicing guides and agreements to which CIT was a party as the servicer of the loans. The Company had established reserves for contingent servicing-related liabilities for CIT’s servicer obligation that shall remain in discontinued operations until the contingency is resolved. Separately, the Company had recognized an indemnification receivable from the FDIC of $29 million as of December 31, 2017 for covered servicing-related obligations related to reverse mortgage loans pursuant to the loss share agreement between CIT Bank and the FDIC related to the acquisition by OneWest Bank from the FDIC of certain assets of IndyMac Federal Bank FSB (“IndyMac”) (the “IndyMac Transaction”). During 2018, the indemnification receivable was reduced to zero as the contingent obligation for FDIC covered loans was no longer deemed probable pursuant to ASC 450 and related ASC 805. See the Company's Report on Form 10-K for the year ended December 31, 2017, Note 5 - Indemnification Assets, for further information.

LOANS	NOTE 3 — LOANS Loans, excluding those reflected as discontinued operations, consist of the following: Loans by Product (dollars in millions) September 30, 2018 December 31, 2017 Commercial loans $ 22,082.7 $ 20,892.1 Direct financing leases and leveraged leases 2,496.8 2,685.8 Total commercial 24,579.5 23,577.9 Consumer loans 5,916.3 5,536.0 Total loans 30,495.8 29,113.9 Loans held for sale (1) 204.1 1,095.7 Loans and held for sale loans (1) $ 30,699.9 $ 30,209.6 (1) Since the Company manages the credit risk and collections of loans held for sale consistently with its loans held for investment, the aggregate amount is presented in this table. As part of the Financial Freedom Transaction, on May 31, 2018, CIT sold its reverse mortgage portfolio comprised of loans and related OREO assets of $884 million and recognized a net pre-tax gain on the sale of $27 million in other non-interest income. The loans were included in loans held for sale in the above table at December 31, 2017. Note 1 – Business and Summary of Significant Accounting Policies The following table presents loans, excluding loans held for sale, by segment, based on obligor location: Loans (dollars in millions) September 30, 2018 December 31, 2017 Domestic Foreign Total Domestic Foreign Total Commercial Banking $ 22,518.2 $ 1,577.5 $ 24,095.7 $ 21,368.7 $ 1,790.6 $ 23,159.3 Consumer Banking (1) 6,400.1 — 6,400.1 5,954.6 — 5,954.6 Total $ 28,918.3 $ 1,577.5 $ 30,495.8 $ 27,323.3 $ 1,790.6 $ 29,113.9 (1) The Consumer Banking segment includes certain commercial loans, primarily consisting of a portfolio of Small Business Administration ("SBA") loans. These loans are excluded from the Consumer loan balances and included in the Commercial loan balances in the tables throughout this note. The following table presents selected components of the net investment in loans: Components of Net Investment in Loans (dollars in millions) September 30, 2018 December 31, 2017 Unearned income $ (749.3 ) $ (727.8 ) Unamortized premiums 18.3 3.7 Accretable yield on PCI loans (944.9 ) (1,063.7 ) Net unamortized deferred costs (1) 79.8 68.7 (1) Balance relates to the Commercial Banking segment . Certain of the following tables present credit-related information at the “class” level. A class is generally a disaggregation of a portfolio segment. In determining the classes, CIT considered the loan characteristics and methods it applies in monitoring and assessing credit risk and performance. Credit Quality Information The following table summarizes commercial loans by the risk ratings that bank regulatory agencies utilize to classify credit exposure and which are consistent with indicators the Company monitors. The consumer loan risk profiles are different from commercial loans, and use loan-to-value (“LTV”) ratios in rating the credit quality, and therefore are presented separately below.

The following table provides a summary of the consumer portfolio credit quality. The amounts represent the carrying value, which differ from unpaid principal balances, and include the premiums or discounts and the accretable yield and non-accretable difference for PCI loans recorded in purchase accounting. Included in the consumer single-family residential (“SFR”) loans are “covered loans” for which the Company can be reimbursed for a substantial portion of future losses under the terms of the loss sharing agreement with the FDIC related to IndyMac, which expires in March 2019. Covered loans are limited to the Legacy Consumer Mortgage ("LCM") division. Due to continued improvement of the covered loan performance, significantly shorter remaining life of the indemnification asset in comparison to the weighted average life of the related covered loans, and significant decline in loss share claims filed with the FDIC in the last six months, CIT performed a collectability assessment of the probable losses to be reimbursed by the FDIC for the remaining indemnification period. Separate from the higher negative yield to amortize the reductions in expected indemnification asset cash flows due to an increase in expected cash flows on the covered loans from improved credit performance, CIT recorded an impairment of $21.2 million, in other non-interest income, to reduce the carrying value of the indemnification asset (included in other assets) to $27.2 million in the quarter ended September 30, 2018, for the amounts deemed uncollectable within the remaining indemnification period based on CIT’s loan level review of the covered loans. Indemnification assets are discussed further in our 2017 Form 10-K, Note 5 — Indemnification Assets Included in the consumer loan balances as of September 30, 2018 and December 31, 2017, were loans with terms that permitted negative amortization with an unpaid principal balance of $413 million and $484 million, respectively. The table below summarizes the consumer loan LTV distribution and the covered loan held for investment balances as of September 30, 2018 and December 31, 2017 for SFR mortgage loans.

Modifications that include a financial concession to the borrower are accounted for as TDRs. See the Company's 2017 Form 10-K for discussion of policies on TDRs. At September 30, 2018, the loans in trial modification period were insignificant The recorded investment of TDRs, excluding those classified as PCI and those within a trial modification period discussed in the preceding paragraph, at September 30, 2018 and December 31, 2017 was $84.6 million and $103.5 million, of which 62% and 63%, respectively, were on non-accrual. Commercial Banking and Consumer Banking receivables accounted for 80% and 20% of the total TDRs, respectively, at September 30, 2018. Commercial Banking and Consumer Banking receivables accounted for 83% and 17% of the total TDRs, respectively at December 31, 2017. There were $14.8 million and $13.4 million as of September 30, 2018 and December 31, 2017, respectively, of commitments to lend additional funds to borrowers whose loan terms have been modified in TDRs. The recorded investment related to modifications qualifying as TDRs that occurred during the quarters ended September 30, 2018 and 2017 were $13.1 million and $39.0 million and $60.9 million and $129.7 million for the nine months ended September 30, 2018 and 2017, respectively. The recorded investment as of September 30, 2018 and 2017 of TDRs that experienced a payment default (payment default is one missed payment), during the quarters ended September 30, 2018 and 2017, and for which the payment default occurred within one year of the modification totaled $0.4 million and $7.5 million, respectively, and $2.4 million and $72.0 million for the nine months ended September 30, 2018 and 2017, respectively. The financial impact of the various modification strategies that the Company employs in response to borrower difficulties is described below. While the discussion focuses on the September 30, 2018 amounts, the overall nature and impact of modification programs were comparable in the prior year. ▪ The nature of modifications qualifying as TDRs based upon recorded investment at September 30, 2018 was comprised of payment deferrals for 32% and covenant relief and/or other for 68%. At December 31, 2017 TDR recorded investment was comprised of payment deferrals for 31% and covenant relief and/or other for 69%. ▪ Payment deferrals result in lower net present value of cash flows, if not accompanied by additional interest or fees, and increased provision for credit losses to the extent applicable. The financial impact of these modifications is not significant given the moderate length of deferral periods. ▪ Interest rate reductions result in lower amounts of interest being charged to the customer, but are a relatively small part of the Company’s restructuring programs. The weighted average change in interest rates for all TDRs occurring during the quarters ended September 30, 2018 and 2017 was not significant. ▪ Debt forgiveness, or the reduction in amount owed by borrower, results in incremental provision for credit losses, in the form of higher charge-offs. While these types of modifications have the greatest individual impact on the allowance, the amounts of principal forgiveness for TDRs occurring during quarters ended September 30, 2018 and 2017 was not significant, as debt forgiveness is a relatively small component of the Company’s modification programs. ▪ The other elements of the Company’s modification programs that are not TDRs, do not have a significant impact on financial results given their relative size, or do not have a direct financial impact, as in the case of covenant changes.

Secured Borrowings At September 30, 2018, the Company had pledged $29.6 billion of assets (including collateral for the FRB discount window that is currently not drawn). The collateral specifically identified and used to calculate available borrowings was $13.6 billion, which included $12.3 billion of loans, $1.0 billion of operating lease assets, $0.2 billion of cash and cash equivalents and $0.1 billion of investment securities. Under the FHLB Facility, CIT Bank, N.A. may at any time grant a security interest in, sell, convey or otherwise dispose of any of the assets used for collateral, provided that CIT Bank, N.A. is in compliance with the collateral maintenance requirement immediately following such disposition and all other requirements of the facility at the time of such disposition. FHLB Advances As of September 30, 2018, the Company had $5.5 billion of financing availability with the FHLB, of which $2.3 billion was unused and available, and $2.3 million was being utilized for issuance of letters of credit related to lease agreements. FHLB Advances as of September 30, 2018 have a weighted average rate of 2.37%. The following table includes the total outstanding FHLB Advances, and respective pledged assets (1) FHLB Advances with Pledged Assets (1) (dollars in millions) September 30, 2018 December 31, 2017 FHLB Advances Pledged Assets FHLB Advances Pledged Assets Total $ 3,150.0 $ 6,602.5 $ 3,695.5 $ 6,154.1 (1) For purposes of this table the term "Pledged Assets" means the assets required under the collateral maintenance requirement in connection with FHLB advances at each of the dates. Other Secured and Structured Financings Set forth in the following table are borrowings and pledged assets related to secured (other than FHLB) and structured financings of CIT-owned subsidiaries and consolidated VIEs. Creditors of these VIEs received ownership and/or security interests in the assets. These entities are intended to be bankruptcy remote so that such assets are not available to creditors of CIT or any affiliates of CIT until and unless the related secured borrowings have been fully discharged. These transactions do not meet accounting requirements for sales treatment and are recorded as secured borrowings. The secured and structured financings as of September 30, 2018 had a weighted average rate of 4.31%, with rates ranging from 0.65% to 5.50%. Other Secured and Structured Financings and Pledged Assets Summary (dollars in millions) September 30, 2018 December 31, 2017 Secured Borrowing Pledged Assets Secured Borrowing Pledged Assets Business Capital $ 697.0 $ 3,070.0 $ 768.8 $ 2,838.6 Rail (1) (2) 589.6 1,059.5 772.6 1,272.0 Total $ 1,286.6 $ 4,129.5 $ 1,541.4 $ 4,110.6 (1) At September 30, 2018, the Dutch TRS Facility related borrowings and pledged assets of $462.7 million and $854.7 million, respectively, were included in Rail. The Dutch TRS Facility is defined in Note 7 — Derivative Financial Instruments. See Note 14 – Subsequent Events relating to CIT’s termination of the Dutch TRS Facility on November 2, 2018 and repayment of related debt in October 2018. (2) At Not included in the above table are secured borrowings of discontinued operations of $213.2 million and $268.2 million at September 30, 2018 and December 31, 2017, respectively. See Note 2 — Discontinued Operations FRB There were no outstanding borrowings with the FRB Discount Window as of September 30, 2018 and December 31, 2017. Variable Interest Entities Described below are the results of the Company’s assessment of its variable interests in order to determine its current status with regards to being the VIE primary beneficiary. Consolidated VIEs The Company utilizes VIEs in the ordinary course of business to support its own and its customers’ financing needs. Each VIE is a separate legal entity and maintains its own books and records. The most significant types of VIEs that CIT utilizes are "on balance sheet" secured financings of pools of leases and loans originated by the Company where the Company is the primary beneficiary. Refer to the Company’s 2017 Form 10-K for further discussion. Unconsolidated VIEs Unconsolidated VIEs include government sponsored entity (“GSE”) securitization structures, private-label securitizations and limited partnership interests where the Company’s involvement is limited to an investor interest in which the Company does not have the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE and limited partnership interests. Although the economic benefit and risk has been transferred to the buyer in connection with the Financial Freedom business sale in the second quarter of 2018, until the required investor consent is obtained from the Government National Mortgage Association (“GNMA”), CIT remains the master servicer for the HECM loans and the GNMA HMBS securitizations. These are VIEs for which CIT is not the primary beneficiary, and which are reported in discontinued operations. The Company, as servicer of these HECM loans, is obligated to fund future borrower advances, which include fees paid to taxing authorities for borrowers’ unpaid taxes and insurance, mortgage insurance premiums and payments made to borrowers for line of credit draws on HECM loans. In addition, the Company is required to repurchase the HECM loans once the outstanding principal balance is equal to or greater than 98% of the maximum claim amount or when the property forecloses to OREO, which reduces the secured borrowing balance. Additionally, the Company services $127.2 million and $140.3 million of HMBS outstanding principal balance at September 30, 2018 and December 31, 2017, respectively, for transferred loans securitized by IndyMac for which OneWest Bank prior to the acquisition had purchased the mortgage servicing rights (“MSRs”) in connection with the IndyMac Transaction. The carrying value of the MSRs was not significant at September 30, 2018 and December 31, 2017. As the HECM loans are federally insured by the FHA and the secured borrowings guaranteed to the investors by GNMA, the Company does not believe maximum loss exposure as a result of its involvement is material. Upon receiving GNMA consent, CIT shall no longer have this servicer obligation and the Company will qualify for sales treatment. See Note 2 — Discontinued Operations. The table below presents potential losses that would be incurred under hypothetical circumstances, such that the value of its interests and any associated collateral declines to zero and assuming no recovery or offset from any economic hedges. The Company believes the possibility is remote under this hypothetical scenario; accordingly, this required disclosure is not an indication of expected loss.

See Note 14 – Subsequent Events relating to CIT’s termination of the Dutch TRS Facility on November 2, 2018. (4) The Company accounts for swap contracts cleared by the Chicago Mercantile Exchange as “settled-to-market” effective January 2017. As a result, variation margin payments are characterized as settlement of the derivative exposure and variation margin balances are netted against the corresponding derivative mark-to-market balances The Company’s swap contracts cleared by LCH Clearnet continue to be accounted for as “collateralized-to-market” and variation margin balances are characterized as collateral against derivative exposures. At September 30, 2018, gross amounts of recognized assets and liabilities were lower by $12.3 million and $2.7 million, respectively. (5) The Company’s derivative transactions are governed by ISDA agreements that allow for net settlements of certain payments as well as offsetting of all contracts with a given counterparty in the event of bankruptcy or default of one of the two parties to the transaction. We believe our ISDA agreements meet the definition of a master netting arrangement or similar agreement for purposes of the above disclosure. In conjunction with the ISDA agreements, the Company has entered into collateral arrangements with its counterparties, which provide for the exchange of cash depending on change in the market valuation of the derivative contracts outstanding. Such collateral is available to be applied in settlement of the net balances upon an event of default of one of the counterparties. (6) Collateral pledged or received is included in Other assets or Other liabilities, respectively. Qualifying Hedges CIT enters into interest rate swap agreements to manage interest rate exposure on its fixed-rate borrowings. The agreements that qualify for hedge accounting are designated as a fair value hedge. The following table represents the impact of fair value hedges on the condensed consolidated statements of income.

(“BV”) was party to a financing facility (the “Dutch TRS Facility”) with Goldman Sachs International (“GSI”). The amount available for advances (otherwise known as the unused portion) was accounted for as a derivative (“TRS Derivative”) and recorded at the estimated fair value. The total facility capacity available under the Dutch TRS Facility was $625 million at September 30, 2018, and December 31, 2017. The utilized portion reflects the borrowing. The aggregate “notional amount” of the TRS Derivative was $209.7 million at September 30, 2018, and $182.4 million at December 31, 2017. The notional amount was calculated as the maximum facility commitment amount, or $625 million, under the Dutch TRS Facility, less the actual adjusted qualifying borrowing base outstanding of $415.3 million at September 30, 2018, and $442.6 million under the facility at December 31, 2017. Based on the Company’s valuation, a liability of $13.3 million and $14.1 million was recorded at September 30, 2018, and December 31, 2017, respectively. The decrease in liability of $1.4 million and $0.8 million were recognized in other non-interest income for the quarter and nine months ended September 30, 2018, respectively. An increase in liability of $1.1 million and $2.4 million was recognized as a reduction to other non-interest income for the quarter and nine months ended September 30, 2017, respectively.

Fair Value Disclosures [Abstract]
FAIR VALUE	NOTE 8 — FAIR VALUE Fair Value Hierarchy The Company measures certain financial assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP also establishes a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three levels. See Note 1 — Business and Summary of Significant Accounting Policies Disclosures that follow in this note exclude assets and liabilities classified as discontinued operations. The following table summarizes the Company’s assets and liabilities measured at estimated fair value on a recurring basis.

See Fair Value of Financial Instruments Debt and Equity Securities Classified as AFS, Securities carried at fair value with changes recorded in net income Derivative Assets and Liabilities Consideration Holdback Liability — In connection with the OneWest acquisition, the parties negotiated certain holdbacks related to select trailing risks, which totaled $116 million and reduced the cash consideration paid at closing. As of June 30, 2018, all holdback obligations were settled with the former OneWest shareholders. As of December 31, 2017, management’s estimate of the probable amount of holdback to be paid was $46 million. Due to the significant unobservable inputs used, these measurements were classified as Level 3. FDIC True-up Liability — The FDIC True-up liability was recorded at estimated fair value as of the Acquisition Date and is measured at fair value at each reporting date until the contingency is resolved. Due to the significant unobservable inputs used, these measurements were classified as Level 3. The following tables summarize information about significant unobservable inputs related to the Company’s categories of Level 3 financial assets and liabilities measured on a recurring basis as of September 30, 2018 and December 31, 2017.

Assets Measured at Estimated Fair Value on a Non-recurring Basis Certain assets or liabilities are required to be measured at estimated fair value on a non-recurring basis subsequent to initial recognition. Generally, these adjustments are the result of LOCOM or other impairment accounting. In determining the estimated fair values, the Company determined that substantially all the changes in estimated fair value were due to declines in market conditions versus instrument specific credit risk. This was determined by examining the changes in market factors relative to instrument specific factors. The following table presents assets measured at estimated fair value on a non-recurring basis for which a non-recurring change in fair value has been recorded in the current year: Carrying Value of Assets Measured at Fair Value on a Non-recurring Basis (dollars in millions) Fair Value Measurements at Reporting Date Using: Total Level 1 Level 2 Level 3 Total Gains (Losses) September 30, 2018 Assets held for sale $ 58.4 $ — $ 9.9 $ 48.5 $ 8.9 Other real estate owned 3.8 — — 3.8 (1.0 ) Impaired loans 87.4 — — 87.4 (38.5 ) Total $ 149.6 $ — $ 9.9 $ 139.7 $ (30.6 ) December 31, 2017 Assets held for sale $ 177.8 $ — $ — $ 177.8 $ (15.0 ) Other real estate owned 18.8 — — 18.8 (4.4 ) Impaired loans 89.1 — — 89.1 (21.9 ) Total $ 285.7 $ — $ — $ 285.7 $ (41.3 ) Assets of continuing operations that are measured at fair value on a non-recurring basis are as follows: Assets Held for Sale — See later in this note for fair value measurements of AHFS. Carrying value of AHFS with impairment approximates fair value at September 30, 2018 and December 31, 2017. Other Real Estate Owned — Estimated fair values of OREO are reviewed on a quarterly basis and any decline in value below cost is recorded as impairment. Estimated fair value approximates carrying value and is generally based on market data, if available or broker price opinions or independent appraisals, adjusted for costs to sell. The weighted average inputs used to estimate the cost to sell were 6.7% at September 30, 2018. Significant unobservable inputs resulted in the Level 3 classification of OREO. Impaired Loans — See later in this note for fair value measurements of impaired loans. As of the reporting date, the carrying value of impaired loans approximated fair value. Fair Values of Financial Instruments The carrying values and estimated fair values of financial instruments presented below exclude leases and certain other assets and liabilities, which were not required for disclosure.

Level 3 fair value at December 31, 2017 included debt securities AFS ($385.8 million), debt securities carried at fair value with changes recorded in net income ($0.4 million), and non-marketable investments ($301.2 million). (2) The indemnification assets relating to the SFR loans purchased in the OneWest Bank Transaction were measured on the same basis as the related indemnified item, and the underlying SFR loans. The estimated fair values reflect the present value of expected reimbursements under the indemnification agreements based on the loan performance discounted at an estimated market rate, and were classified as Level 3. The indemnification assets included in the above table do not include Agency claims indemnification (the balance of which was zero at September 30, 2018 and $28.9 million at December 31, 2017), as they are not considered financial instruments. (3) Other assets subject to fair value disclosure primarily include unsecured counterparty receivables, accrued interest receivable and miscellaneous receivables. The unsecured counterparty receivables primarily consisted of amounts owed to CIT for debt discount, return of collateral and settlements resulting from market value changes to asset-backed securities underlying the TRS. The remaining assets have carrying values that approximated fair value, generally due to their short-term nature. (4) Deposits and borrowings include accrued interest, which is included in “Other liabilities”. (5) Other liabilities subject to fair value disclosure include accounts payable, accrued liabilities, customer security and maintenance deposits and miscellaneous liabilities. The fair value of these approximated carrying value. The methods and assumptions used to estimate the fair value of each class of financial instruments were: Derivative Assets and Liabilities —Derivatives were valued using models that incorporate inputs depending on the type of derivative. Besides the fair value of the TRS Derivative, written options on certain CIT Bank certificate of deposits and credit derivatives that were estimated using Level 3 inputs, most derivative instruments were valued using a Level 2 methodology. See for notional principal amounts and fair values Investment Securities — Debt securities classified as AFS —Investments in U.S. federal government agency securities, U.S. Treasury Notes, agency pass-through and supranational securities were valued using Level 2 inputs. The market for non-Agency MBS is not active; therefore the estimated fair value was determined using a discounted cash flow technique. Given the lack of observable market data, the estimated fair value of the non-agency MBS was classified as Level 3. Non-marketable equity securities utilize Level 3 inputs to estimate fair value and were generally recorded under the cost or equity method of accounting. For investments in limited partnership equity interests, the Company used the net asset value provided by the fund manager as an appropriate measure of fair value. Securities carried at fair value with changes recorded in net income — included equity securities AFS that were reclassified to securities carried at fair value with changes recorded in net income upon the adoption of as of January 1, 2018. A majority were valued using Level 2 inputs and the remaining were valued using Level 1 inputs. Assets held for sale — As there was no liquid secondary market for most AHFS, the fair value was estimated based on Level 3 inputs. Loans — Within the Loans category, there are several types of loans as follows: Commercial and Consumer Loans — Commercial and consumer loans are generally valued individually, while small ticket commercial loans and equipment loans are valued on an aggregate portfolio basis. As there is no liquid secondary market for most loans, the fair value was estimated based on analyses that used Level 3 inputs at both September 30, 2018 and December 31, 2017. Impaired Loans — The value of impaired loans was assessed through the evaluation of aggregate carrying values of impaired loans relative to contractual amounts owed (unpaid principal balance) from customers. See — . PCI loans — These loans were valued by grouping the loans into performing and non-performing groups and stratifying the loans based on common risk characteristics such as product type, FICO score and other economic attributes. Due to the significance of the unobservable inputs, these loans are classified as Level 3. Deposits — The estimated fair value of deposits with no stated maturity, such as demand deposit accounts (including custodial deposits), money market accounts, and savings accounts was the amount payable on demand at the reporting date. The fair value of time deposits is estimated using Level 3 inputs. Borrowings The Level 2 fair value of borrowings were valued using market inputs and discounted value of the contractual cash flows using current estimated market discount rates for borrowings with similar terms, remaining maturities and put dates and did not require significant judgment . Unsecured debt — Unsecured debt included both senior debt and subordinated debt, which was approximately $4.3 billion par value at September 30, 2018 and $3.8 billion at December 31, 2017. Secured borrowings — Secured borrowings included both structured financings and FHLB advances. Of the total estimated fair value of structured financing, approximately $3.6 billion par value at September 30, 2018 and $4.3 billion at December 31, 2017 were Level 2. The estimated fair value of FHLB advances was based on the discounted cash flow model. The cash flows were calculated using the contractual features of the advance and then discounted using observable rates. The Level 3 fair value of borrowings included: Secured borrowings — Market estimates were not available for approximately $0.8 billion par value of structured financings at September 30, 2018, and $1.0 billion at December 31, 2017, therefore values were estimated using Level 3 inputs. Credit balances of factoring clients — The impact of the time value of money from the unobservable discount rate for credit balances of factoring clients is inconsequential due to the short term nature of these balances (typically 90 days or less), therefore, the carrying value approximated fair value, and the credit balances were classified as Level 3.

Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 10 — INCOME TAXES The Company’s global effective income tax rate from continuing operations including discrete tax items for the third quarter and nine months ended September 30, 2018 was 24.2% and 26.9%, respectively, up from (116.3)% in the prior year quarter and (38.7)% in the nine months ended September 30, 2017. The quarterly income tax expense is based on a projection of the Company’s annual effective tax rate. This annual effective tax rate is applied to the year-to-date consolidated pre-tax income to determine the interim provision for income taxes before discrete items. The year-to-date impact of any change in the projected annual effective tax rate from the prior quarter estimate is included in the current quarter income tax expense. The effective tax rate each period is also impacted by a number of factors, including the relative mix of domestic and international earnings, effects of changes in enacted tax laws, adjustments to the valuation allowances, and discrete items. The currently forecasted effective tax rate may vary from the actual year-end 2018 effective tax rate due to the changes in these factors. 2017 U.S. Tax Reform Legislation The Tax Cuts and Jobs Act (“TCJA”) was enacted on December 22, 2017. The TCJA required management to make certain adjustments to the Company’s year-end financial statements for the effects of the law relating to the remeasurement of deferred taxes, liabilities for taxes due on mandatory deemed repatriation, liabilities for taxes due on other foreign income, and the reassessment of the Company’s valuation allowance. The SEC staff has afforded registrants a measurement period to record adjustments for the effects of the law, per Staff Accounting Bulletin No. 118 Income Tax Accounting Implications of the Tax Cuts and Jobs Act Valuation Allowances The Company established valuation allowances (“VAs”) against certain U.S. federal, U.S. state, and international deferred tax assets (“DTAs”) that are not expected to be realized in the future. The Company maintained a VA of $208.6 million against U.S. state DTAs on certain state net operating losses and a $28.6 million VA against certain non-U.S. reporting entities' net DTAs as of September 30, 2018. In 2017, the Company reported a net $177.4 million U.S. income tax benefit comprised of a gross $234.2 million tax benefit on a capital loss of $610.5 million realized on the liquidation of a wholly-owned foreign subsidiary partially offset by a $56.8 million charge to establish a VA against the unused portion of the capital loss. As a result of the change in the U.S. Federal income tax rate from 35 percent to 21 percent beginning in 2018, the VA against the capital loss carryforwards was revalued to $39.6 million as of December 31, 2017. As of the third quarter of 2018, the Company maintained a U.S. Federal and state VA of $15.8 million against certain capital loss carryforwards, down from $39.6 million as of December 31, 2017. The reduction was attributable to changes in expected capital gains and additional net capital gains recognized year to date in the normal course of business as well as a reduction to the DTA on capital loss carryforward and associated VA. The Company will recognize the income tax benefit on the remaining portion of the DTA subject to the VA to the extent of additional capital gains. Capital losses can be carried forward for five years to offset capital gains. The Company’s ability to recognize DTAs is evaluated on a quarterly basis to determine if there are any significant events that would affect its ability to utilize existing DTAs. If events are identified that affect its ability to utilize its DTAs, VAs may be adjusted accordingly. Liabilities for Uncertain Tax Positions The Company’s liability for uncertain tax positions ("UTPs") before interest and penalties was $13.3 million at September 30, 2018 and $13.5 million at December 31, 2017. The Company anticipates changes to its UTP liability upon the resolution of open tax matters and closure of statutes of limitations. The Company’s accrued liability for interest and penalties totaled $7.1 million at September 30, 2018 and $6.3 million at December 31, 2017. Management believes that it is reasonably possible the total potential liability may be increased or decreased by $5 to $10 million within the twelve months following the reporting date because of anticipated settlement with taxing authorities. The Company recognizes accrued interest and penalties on unrecognized tax benefits in income tax expense.

Included in the table above are commitments that have been extended to and accepted by customers, clients or agents, but on which the criteria for funding have not been completed of $1,616.3 million at September 30, 2018 and $950.3 million at At September 30, 2018, substantially all undrawn financing commitments were senior facilities. Most of the Company’s undrawn and available financing commitments are in the Commercial Banking segment. The table above excludes uncommitted revolving credit facilities extended by Business Capital to its’ clients for working capital purposes. In connection with these facilities, Business Capital has the sole discretion throughout the duration of these facilities to determine the amount of credit that may be made available to its clients at any time and whether to honor any specific advance requests made by its clients under these credit facilities. Consumer The Company sold its reverse mortgage portfolio in connection with the Financial Freedom Transaction on May 31, 2018. Prior to the sale, the Company was committed to fund draws on certain reverse mortgages in conjunction with loss sharing agreements with the FDIC from the OneWest acquisition. The FDIC agreed to indemnify the Company for losses on the first $200 million of draws that occur subsequent to the purchase date (post March 2009). As of December 31, 2017, $134 million had been advanced on the reverse mortgage loans post March 2009 with exposure for additional draws of $66 million. See Note 5 — Indemnification Assets Separately, the Company is committed to fund draws on certain home equity lines of credit (“HELOCs”). Under the HELOC participation and servicing agreement entered into with the FDIC, the FDIC agreed to reimburse the Company for a portion of the draws that the Company funded on the purchased HELOCs from the OneWest acquisition. Letters of Credit In the normal course of meeting the needs of clients, CIT sometimes enters into agreements to provide financing and letters of credit. Standby letters of credit obligate the issuer of the letter of credit to pay the beneficiary if a client on whose behalf the letter of credit was issued does not meet its obligation. These financial instruments generate fees and involve, to varying degrees, elements of credit risk in excess of amounts recognized in the Condensed Consolidated Balance Sheets. To minimize potential credit risk, CIT generally requires collateral and in some cases additional forms of credit support from the client. Deferred Purchase Agreements A Deferred Purchase Agreement (“DPA”) is provided in conjunction with factoring, whereby CIT provides a client with credit protection for trade receivables without purchasing the receivables. The trade receivable terms are generally 90 days or less. If the client’s customer is unable to pay an undisputed receivable solely as the result of credit risk, then CIT purchases the receivable from the client. The outstanding amount in the table above is the maximum potential exposure that CIT would be required to pay under all DPAs. This maximum amount would only occur if all receivables subject to DPAs default in the manner described above, thereby requiring CIT to purchase all such receivables from the DPA clients. The table above includes $2,020 million and $1,979 million of DPA credit protection at September 30, 2018 and The methodology used to determine the DPA liability is similar to the methodology used to determine the allowance for loan losses associated with the finance loans, which reflects embedded losses based on various factors, including expected losses reflecting the Company’s internal customer and facility credit ratings. The liability recorded in Other Liabilities related to the DPAs totaled $6.6 million and $5.3 million at September 30, 2018 and Purchase and Funding Commitments CIT’s purchase commitments primarily relate to the Rail and Equipment Finance businesses. Other Commitments The Company has commitments to invest in affordable housing investments, and other investments qualifying for community reinvestment tax credits. These commitments were $116 million at September 30, 2018 and $67 million at

Loss Contingency [Abstract]
CONTINGENCIES	NOTE 12 — CONTINGENCIES Litigation and other Contingencies CIT is involved, and from time to time in the future may be involved, in a number of pending and threatened judicial, regulatory, and arbitration proceedings as well as proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies. These matters arise in connection with the conduct of CIT’s business. At any given time, CIT may also be in the process of responding to subpoenas, requests for documents, data and testimony relating to such matters and engaging in discussions to resolve the matters (all of the foregoing collectively being referred to as, “Litigation”). While most Litigation relates to individual claims, CIT is also subject to putative class action claims and similar broader claims. In view of the inherent difficulty of predicting the outcome of Litigation matters, particularly when such matters are in their early stages or where the claimants seek indeterminate damages, CIT cannot state with confidence what the eventual outcome of the pending Litigation will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, fines, or penalties related to each pending matter will be, if any. In accordance with applicable accounting guidance, CIT establishes reserves for Litigation when those matters present loss contingencies as to which it is both probable that a loss will occur and the amount of such loss can be reasonably estimated. Based on currently available information, CIT believes that the outcome of Litigation that is currently pending will not have a material adverse effect on the Company’s financial condition, but may be material to the Company’s operating results or cash flows for any particular period, depending in part on its operating results for that period. The actual results of resolving such matters may be substantially higher than the amounts reserved. For certain Litigation matters in which the Company is involved, the Company is able to estimate a range of reasonably possible losses in excess of established reserves and insurance. For other matters for which a loss is probable or reasonably possible, such an estimate cannot be determined. For Litigation and other matters where losses are reasonably possible, management currently estimates the aggregate range of reasonably possible losses as up to $65 million in excess of any established reserves and any insurance we reasonably believe we will collect related to those matters. This estimate represents reasonably possible losses (in excess of established reserves and insurance) over the life of such Litigation, which may span a currently indeterminable number of years, and is based on information currently available as of September 30, 2018. The Litigation matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those Litigation matters for which an estimate is not reasonably possible or as to which a loss does not appear to be reasonably possible, based on current information, are not included within this estimated range and, therefore, this estimated range does not represent the Company’s maximum loss exposure. The foregoing statements about CIT’s Litigation are based on the Company’s judgments, assumptions, and estimates and are necessarily subjective and uncertain. The Company has several hundred threatened and pending judicial, regulatory and arbitration proceedings at various stages. Several of the Company’s significant Litigation matters are described below. Brazilian Tax Matter Banco Commercial Investment Trust do Brasil S.A. (“Banco CIT”), CIT’s Brazilian bank subsidiary, was sold in a stock sale in the fourth quarter of 2015, thereby transferring the legal liabilities of Banco CIT to the buyer. Under the terms of the stock sale, CIT remains liable for indemnification to the buyer for any losses resulting from certain Imposto Sobre Circulaco de Mercadorias e Servicos (“ICMS”) tax appeals relating to disputed local tax assessments on leasing services and importation of equipment (the “ICMS Tax Appeals”). Notices of infraction were issued to Banco CIT relating to the payment of ICMS taxes charged by Brazilian states in connection with the importation of equipment. The state of São Paulo claims that Banco CIT should have paid it ICMS taxes for tax years 2006 - 2009 because Banco CIT, the purchaser, was located in São Paulo. Instead, the ICMS taxes were paid to the state of Espirito Santo where the imported equipment arrived. A regulation issued by São Paulo in December 2013 reaffirms a 2009 agreement by São Paulo to conditionally recognize ICMS tax payments made to Espirito Santo. An assessment related to taxes paid to Espirito Santo was upheld in a ruling issued by the administrative court in May 2014. That ruling has been appealed. Another assessment related to taxes paid to Espirito Santo remains pending. Petitions seeking São Paulo’s recognition of the taxes paid to Espirito Santo were also filed in a general amnesty program. In the first quarter of 2018, CIT was advised that the larger of the two amnesty petitions had been granted and dismissal of that matter is pending with the court. Hawaiian Foreclosure Litigation Claims Based on recent rulings of the Hawaii Supreme Court, lawsuits have been filed against CIT in Hawaii alleging technical violations in non-judicial foreclosures. Similar cases have been filed against other mortgage lenders in Hawaii. The Hawaii Supreme Court did not establish a clear methodology for calculating alleged damages if a violation is proven and there is substantial dispute in this regard. In many instances the borrower had no equity in the home at the time of foreclosure. Damages sought in these cases include any lost equity, compensation for loss of use of the house and, in some cases, treble or punitive damages under Hawaii's unfair practices law. HUD OIG Investigation In 2009, OneWest Bank acquired the reverse mortgage loan portfolio and related servicing rights of Financial Freedom Senior Funding Corporation, including HECM loans, from the FDIC as Receiver for IndyMac Federal Bank. HECM loans are insured by the FHA, and administered by HUD. In addition, Financial Freedom is the servicer of HECM loans owned by third party investors. Beginning in the third quarter of 2015, the Office of the Inspector General for HUD (the “HUD OIG”), served a series of subpoenas on the Company regarding HECM loans. The subpoenas requested documents and other information related to Financial Freedom’s HECM loan origination and servicing business, including the curtailment of interest payments on HECM insurance claims. On May 16, 2017, CIT entered into a settlement of approximately $89 million to resolve the servicing related claims. The settlement was within CIT’s existing reserves and included interest to be reimbursed to HUD. CIT has provided information and documents responsive to the subpoena’s request for information relating to the mortgage originations and does not currently expect the outcome of the remaining loan origination matter to have a material adverse effect on CIT’s financial condition or results of operations. NY Attorney General In the second quarter of 2017, the Office of the Attorney General of the State of New York (“NYAG”), served a subpoena on the Company regarding HECM loans. The subpoena requested documents and other information related to Financial Freedom’s HECM loan business in the State of New York. The NYAG subsequently withdrew the subpoena and has requested the Company’s continued voluntary cooperation with the inquiry. The Company has cooperated with the NYAG’s office and has produced certain documents. The Company does not have sufficient information to make an assessment of the outcome or the impact of the NYAG’s ongoing inquiry.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	NOTE 14 — SUBSEQUENT EVENTS Sale of NACCO On October 4, 2018, CIT sold NACCO, the Company’s European railcar leasing business. With the closing of the NACCO sale, CIT fully divested its interest in NACCO as of October 4, 2018. Railcar loans and leases of approximately $1.2 billion were sold and we expect to recognize a pretax gain of approximately $30-35 million in the fourth quarter. The Company expects to use a portion of the net proceeds received of approximately $1.1 billion to fund the termination of the Dutch TRS Facility (discussed below) and the redemption of a related Railcar Securitization (defined below). The remaining proceeds will be used to return capital to shareholders under the remaining amount of the Company’s common equity capital return, to reduce unsecured debt (discussed below), and for general corporate purposes. Termination of Dutch TRS Facility On October 5, 2018, BV issued an Optional Termination Notice (as that term is defined for purposes of that certain Master Agreement) to GSI to terminate the $625 million Dutch TRS Facility between BV and GSI. Pursuant to the Optional Termination Notice, the Dutch TRS Facility was terminated on November 2, 2018 (the “Optional Termination Date”). The exercise of BV’s option to terminate the Dutch TRS Facility prior to maturity required a payment to GSI on November 2, 2018 of the present value of the remaining facility fee (the “Optional Termination Fee”). The Optional Termination Fee and the reduction of the liability associated with the TRS Derivative are expected to result in net pretax charges for the Company of approximately $70 - $75 million in the fourth quarter of 2018. Redemption of the Railcar Securitization On October 25, 2018, CIT repaid approximately $465 million of secured financings of the Company’s railcar asset backed securitization vehicle (the “Railcar Securitization”), which was the reference obligation under the Dutch TRS Facility. In addition, the termination of the Dutch TRS Facility and redemption of the associated reference obligation Railcar Securitization resulted in the unencumbering of approximately $775 million of railcar assets. On November 1, 2018, the Company sold approximately $350 million of railcar assets in the Railcar Securitization to CIT Bank. Approximately $300 million of proceeds from the sale of NACCO, net of cash held by the securitization trust and other collateral held by the securitization trustee and the counterparty on the Dutch TRS Facility, was used for the redemption of the Railcar Securitization and the termination of the Dutch TRS Facility, including payment of the Optional Termination Fee. Debt Redemptions On October 19 and November 2, 2018, we announced our intent to redeem the outstanding 5.375% senior unsecured notes due May 2020, which totaled approximately $431 million at September 30, 2018, which we will redeem using net proceeds from the NACCO sale and the sale of rail assets to CIT Bank. The unsecured debt redemptions are expected to result in debt extinguishment losses of approximately $15 million in the fourth quarter.

Business and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2018
Accounting Policies [Abstract]
Basis of Financial Information	Basis of Financial Information These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q for interim financial information and accordingly do not include all information and note disclosures required by generally accepted accounting principles in the United States of America (“GAAP”) for complete financial statements. The financial statements in this Form 10-Q, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of CIT’s financial position, results of operations and cash flows in accordance with GAAP. These consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2017 ("2017 Form 10-K"). The accounting and financial reporting policies of CIT conform to GAAP and the preparation of the consolidated financial statements requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates and assumptions. Some of the more significant estimates include: allowance for loan losses, loan impairment, fair value determination, lease residual values, liabilities for uncertain tax positions, realizability of deferred tax assets, purchase accounting adjustments, indemnification assets, goodwill, intangible assets, and contingent liabilities, including amounts associated with discontinued operations. Additionally where applicable, the policies conform to accounting and reporting guidelines prescribed by bank regulatory authorities.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include financial information related to CIT and its majority-owned subsidiaries and those VIEs where the Company is the primary beneficiary. In preparing the consolidated financial statements, all significant intercompany accounts and transactions have been eliminated. Assets held in an agency or fiduciary capacity are not included in the consolidated financial statements. The current period’s results of operations do not necessarily indicate the results that may be expected for any other interim period or for the full year as a whole.
Discontinued Operations	Discontinued Operations Discontinued Operations as of September 30, 2018 and December 31, 2017 included assets and liabilities of (i) the Business Air business and (ii) the Financial Freedom business. Income from discontinued operations reflects the activities of the Business Air and Financial Freedom businesses for the quarter and nine months ended September 30, 2018 and 2017, and Commercial Air (a component of Aerospace) for the nine months ended September 30, 2017. We completed the sale of our Commercial Air business on April 4, 2017. The Financial Freedom business, a former division of CIT Bank that serviced reverse mortgage loans, was acquired in conjunction with the OneWest Transaction in 2015 and was sold on May 31, 2018. The sale included all the operations, mortgage servicing rights and related servicing assets and liabilities, although certain assets and liabilities of the Financial Freedom business were still held by CIT Bank at September 30, 2018 and will continue to be held until the required investor consent is received to qualify for sale treatment. See further discussion in Note 2 — Discontinued Operations. reported in continuing operations, and which was serviced by the Financial Freedom business. ee further discussion in Note 3 — Loans
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Significant accounting policies are included in the Company's 2017 Form 10-K. Effective January 1, 2018, CIT changed its accounting policy for revenue recognition resulting from the adoption of Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers . Other Newly Adopted Accounting Standards Revenue Recognition On January 1, 2018, CIT adopted ASU 2014-09, Revenue Recognition - Revenue from Contracts with Customers (ASC 606) "Interest Income" and "Rental Income on Operating Leases", CIT's two largest revenue items, are out of scope of the new guidance, as are many other revenues relating to other financial assets and liabilities, including loans, leases, securities, and derivatives. As a result, the implementation of the new guidance was limited to certain revenue streams within Non-Interest Income, including some immaterial bank related fees and gains or losses related to the sale and disposition of leased equipment and OREO, which is accounted for under ASC 610-20, Gains and Losses From the Derecognition of Nonfinancial Assets, CIT evaluated its in-scope revenue streams under the five-step model and concluded that ASU 2014-09 did not materially impact the current practice of revenue recognition as ASC 606 is consistent with the current accounting policy being applied by the Company for these revenues. Therefore, no change in the timing or amount of income recognized was identified. CIT also determined that costs incurred to obtain or fulfill contracts and financing components relating to in-scope revenue streams were immaterial to the Company. Non-interest revenue, including amounts related to the sale and disposition of leased equipment and OREO, is recognized at an amount reflecting the consideration received, or expected to be received, when control of goods or services is transferred, which generally occurs when services are provided or control of leased equipment or OREO is liquidated. ASU 2014-09 was adopted using the modified retrospective transition method. CIT elected to apply this guidance only to contracts that were not completed at the date of the initial application. The adoption did not have a significant impact on CIT’s financial statements or disclosures. No adjustment to the opening balance of retained earnings was necessary. Interest income on held for investment ("HFI") loans is recognized using the effective interest method or on a basis approximating a level rate of return over the life of the asset. Interest income includes components of accretion of the fair value discount on loans and lease receivables recorded in connection with Purchase Accounting Adjustments (“PAA”), which are accreted using the effective interest method as a yield adjustment over the remaining contractual term of the loan and recorded in interest income. If the loan is subsequently classified as assets held for sale ("AHFS"), accretion (amortization) of the discount (premium) will cease. Rental revenue on operating leases is recognized on a straight line basis over the lease term and is included in Non-interest Income. Intangible assets related to acquisitions completed by the Company and Fresh Start Accounting (“FSA”) adjustments that were applied as of December 31, 2009 (the Convenience Date), were recorded to adjust the carrying value of above or below market operating lease contracts to their fair value. The FSA adjustments (net) are amortized into rental income on a straight line basis over the remaining term of the respective lease. The recognition of interest income (including accretion) on commercial loans (exclusive of small ticket commercial loans) is suspended and an account is placed on non-accrual status when, in the opinion of management, full collection of all principal and interest due is doubtful. All future interest accruals, as well as amortization of deferred fees, costs, purchase premiums or discounts are suspended. To the extent the estimated cash flows, including fair value of collateral, does not satisfy both the principal and accrued interest outstanding, accrued but uncollected interest at the date an account is placed on non-accrual status is reversed and charged against interest income. Subsequent interest received is applied to the outstanding principal balance until such time as the account is collected, charged-off or returned to accrual status. Loans that are on cash basis nonaccrual do not accrue interest income; however, payments designated by the borrower as interest payments may be recorded as interest income. To qualify for this treatment, the remaining recorded investment in the loan must be deemed fully collectable. The recognition of interest income (including accretion) on consumer mortgages and small ticket commercial loans and lease receivables is suspended and all previously accrued but uncollected revenue is reversed, when payment of principal and/or interest is contractually delinquent for 90 days or more. Accounts, including accounts that have been modified, are returned to accrual status when, in the opinion of management, collection of remaining principal and interest is reasonably assured, and there is a sustained period of repayment performance for a minimum of six months. The recognition of interest income on reverse mortgages is suspended upon the latter of the foreclosure sale date or date on which marketable title has been acquired (i.e., property becomes OREO). The Company periodically modifies the terms of a loan in response to borrowers’ financial difficulties. These modifications may include interest rate changes, principal forgiveness or payment deferments. Loans that are modified, where a concession has been made to the borrower, are accounted for as Troubled Debt Restructurings (“TDRs”). TDRs are generally placed on nonaccrual upon their restructuring and remain on non-accrual until, in the opinion of management, collection of remaining principal and interest is reasonably assured, and upon collection of six consecutive scheduled payments. Purchased credit impaired ("PCI") loans in pools that the Company may modify as TDRs are not within the scope of the accounting guidance for TDRs. Other Newly Adopted Accounting Standards The following pronouncements were issued by the Financial Accounting Standards Board (“FASB”) and adopted by CIT as of January 1, 2018. Refer to Note 1 - Business and Summary of Significant Accounting Policies on Form 10-Q for the quarter ended March 31, 2018 for a detailed description of these pronouncements: • ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. • ASU 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10). • ASU 2016-16, Income Taxes (Topic 740): Intra - Entity Transfers of Assets Other Than Inventory • ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments • ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cas • ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business • ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost • ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting • ASU 2018-02, Income Statement Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The following pronouncements were issued by FASB and adopted by CIT as of July 1, 2018. Intangibles – Goodwill and Other – Internal-Use Software ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement CIT early adopted ASU 2018-15 as of July 1, 2018 by applying the guidance prospectively to all implementation costs incurred after the date of adoption. Capitalized implementation costs and amortization expense related to the development of internal financial planning and workflow tools are reflected in “Other assets” and “Operating expenses” within the Company’s Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Income, respectively. The adoption did not have a material impact on CIT’s consolidated financial statements and disclosures. Fair Value Measurement ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement CIT early adopted the removed and modified disclosure requirements in ASU 2018-13 as of July 1, 2018. The amendment on changes to the narrative description of measurement uncertainty was applied prospectively for the most recent period presented. All other amendments were applied retrospectively to all periods presented. The adoption of this standard did not have a material impact on CIT’s disclosures as disclosure enhancements are more qualitative in nature. Recent Accounting Pronouncements The following accounting pronouncements were issued by the FASB but are not yet effective for CIT.

Litigation and other Contingencies	Litigation and other Contingencies CIT is involved, and from time to time in the future may be involved, in a number of pending and threatened judicial, regulatory, and arbitration proceedings as well as proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies. These matters arise in connection with the conduct of CIT’s business. At any given time, CIT may also be in the process of responding to subpoenas, requests for documents, data and testimony relating to such matters and engaging in discussions to resolve the matters (all of the foregoing collectively being referred to as, “Litigation”). While most Litigation relates to individual claims, CIT is also subject to putative class action claims and similar broader claims. In view of the inherent difficulty of predicting the outcome of Litigation matters, particularly when such matters are in their early stages or where the claimants seek indeterminate damages, CIT cannot state with confidence what the eventual outcome of the pending Litigation will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, fines, or penalties related to each pending matter will be, if any. In accordance with applicable accounting guidance, CIT establishes reserves for Litigation when those matters present loss contingencies as to which it is both probable that a loss will occur and the amount of such loss can be reasonably estimated. Based on currently available information, CIT believes that the outcome of Litigation that is currently pending will not have a material adverse effect on the Company’s financial condition, but may be material to the Company’s operating results or cash flows for any particular period, depending in part on its operating results for that period. The actual results of resolving such matters may be substantially higher than the amounts reserved. For certain Litigation matters in which the Company is involved, the Company is able to estimate a range of reasonably possible losses in excess of established reserves and insurance. For other matters for which a loss is probable or reasonably possible, such an estimate cannot be determined. For Litigation and other matters where losses are reasonably possible, management currently estimates the aggregate range of reasonably possible losses as up to $65 million in excess of any established reserves and any insurance we reasonably believe we will collect related to those matters. This estimate represents reasonably possible losses (in excess of established reserves and insurance) over the life of such Litigation, which may span a currently indeterminable number of years, and is based on information currently available as of September 30, 2018. The Litigation matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those Litigation matters for which an estimate is not reasonably possible or as to which a loss does not appear to be reasonably possible, based on current information, are not included within this estimated range and, therefore, this estimated range does not represent the Company’s maximum loss exposure. The foregoing statements about CIT’s Litigation are based on the Company’s judgments, assumptions, and estimates and are necessarily subjective and uncertain. The Company has several hundred threatened and pending judicial, regulatory and arbitration proceedings at various stages.

See Note 14 – Subsequent Events relating to CIT’s termination of the Dutch TRS Facility on November 2, 2018. (4) The Company accounts for swap contracts cleared by the Chicago Mercantile Exchange as “settled-to-market” effective January 2017. As a result, variation margin payments are characterized as settlement of the derivative exposure and variation margin balances are netted against the corresponding derivative mark-to-market balances The Company’s swap contracts cleared by LCH Clearnet continue to be accounted for as “collateralized-to-market” and variation margin balances are characterized as collateral against derivative exposures. At September 30, 2018, gross amounts of recognized assets and liabilities were lower by $12.3 million and $2.7 million, respectively. (5) The Company’s derivative transactions are governed by ISDA agreements that allow for net settlements of certain payments as well as offsetting of all contracts with a given counterparty in the event of bankruptcy or default of one of the two parties to the transaction. We believe our ISDA agreements meet the definition of a master netting arrangement or similar agreement for purposes of the above disclosure. In conjunction with the ISDA agreements, the Company has entered into collateral arrangements with its counterparties, which provide for the exchange of cash depending on change in the market valuation of the derivative contracts outstanding. Such collateral is available to be applied in settlement of the net balances upon an event of default of one of the counterparties. (6) Collateral pledged or received is included in Other assets or Other liabilities, respectively.

Level 3 fair value at December 31, 2017 included debt securities AFS ($385.8 million), debt securities carried at fair value with changes recorded in net income ($0.4 million), and non-marketable investments ($301.2 million). (2) The indemnification assets relating to the SFR loans purchased in the OneWest Bank Transaction were measured on the same basis as the related indemnified item, and the underlying SFR loans. The estimated fair values reflect the present value of expected reimbursements under the indemnification agreements based on the loan performance discounted at an estimated market rate, and were classified as Level 3. The indemnification assets included in the above table do not include Agency claims indemnification (the balance of which was zero at September 30, 2018 and $28.9 million at December 31, 2017), as they are not considered financial instruments. (3) Other assets subject to fair value disclosure primarily include unsecured counterparty receivables, accrued interest receivable and miscellaneous receivables. The unsecured counterparty receivables primarily consisted of amounts owed to CIT for debt discount, return of collateral and settlements resulting from market value changes to asset-backed securities underlying the TRS. The remaining assets have carrying values that approximated fair value, generally due to their short-term nature. (4) Deposits and borrowings include accrued interest, which is included in “Other liabilities”. (5) Other liabilities subject to fair value disclosure include accounts payable, accrued liabilities, customer security and maintenance deposits and miscellaneous liabilities. The fair value of these approximated carrying value.
