Business And Summary Of Significant 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”), has provided financial solutions to its clients since its formation in 1908. The Company provides financing, leasing and advisory services principally to middle market companies in a wide variety of industries primarily in North America, and equipment financing and leasing solutions to the transportation industry worldwide. CIT is a bank holding company (“BHC”) and a financial holding company (“FHC”). Through its bank subsidiary, CIT Bank, N.A., CIT provides a full range of commercial and consumer banking and related services to customers through 70 branches located in Southern California and its online bank, bankoncit.com. As previously disclosed, on October 6, 2016, we announced a definitive agreement to sell our commercial aircraft leasing business (“Commercial Air”), to Avolon Holdings Limited (“Avolon”), an international aircraft leasing company and a wholly-owned subsidiary of Bohai Capital Holding Co. Ltd. (“Bohai”) (the “Commercial Air Sale”). On April 4, 2017, CIT completed the Commercial Air sale. 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, N.A. 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 our Form 10-K for the year ended December 31, 2016. The accounting and financial reporting policies of CIT Group Inc. 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. Som e o f th e mo re signifi can t estimate s include : allowanc e fo r loa n losses , loan impairment , fai r valu e determination , leas e r esidua l values , liabili tie s fo r uncertai n ta x positions , r ealizabilit y o f defer r e d ta x assets, pu r chas e accountin g adjustments , indemnificatio n assets , good will , intangibl e assets , an d contingen t liabilities, including amounts associated with the discontinued operation . Additionally whe re applicable , th e policie s confor m t o accountin g an d r eportin g guideline s p r escribe d b y ban k r egulator y authorities. Principles of Consolidation The accompanying consolidated financial statements include financial information related to CIT Group Inc. and its majority-owned subsidiaries and those variable interest entities (“VIEs”) where the Company is the primary beneficiary. In preparing the consolidated financial statements, all significant inter-company 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 March 31, 2017 and December 31, 2016 included certain assets and liabilities of the Commercial Air business, the Business Air business, along with the Financial Freedom business that was acquired as part of the OneWest Transaction. Income from discontinued operations reflects the activities of the Aerospace (Commercial Air and Business Air) and Financial Freedom businesses for the quarters ended March 31, 2017 and 2016.  See further discussions in Note 2 - Discontinued Operations.  Revisions of Previously Issued Statements of Cash Flows  The Company has revised the Statement of Cash Flows for the three months ended March 31, 2016 in connection with immaterial errors impacting the classification of certain balances between line items and categories as previously disclosed in its Form 10-K, Note 29 – Selected Quarterly Financial Data , for the year ended December 31, 2016. The misclassifications resulted in an overstatement of net cash flows provided by operations of $166.4 million, an overstatement of net cash flows used in investing activities of $203.9 million, and an understatement of net cash flows used in financing activities of $35.2 million. The Company evaluated the impact of the errors and has concluded that individually and in the aggregate, the errors were not material to any previously issued financial statements.  Cash Flow balances disclosed in the December 31, 2016 Form 10-K have been updated to reflect the adoption of ASU 2016 ‐ 09: Compensation—Stock Compensation (Topic 718) , as discussed later in this Note. SIGNIFICANT ACCOUNTING POLICIES Significant accounting policies are included with the current Form 10-K for the year ended December 31, 2016 . There were no material changes to these policies during the three months ended March 31, 2017.  Financial Accounting Standards Board (“FASB”) Standards Adopted since January 1, 2017  Accounting Standards Update (“ASU”) 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument does not, in and of itself, require de-designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The standard was adopted as of January 1, 2017. Historically, CIT has not novated any derivative instrument that was designated as a hedging instrument and as such the adoption of this ASU has no impact on CIT’s Consolidated Financial Statements.  ASU 2016-06, Derivatives and Hedging (Top 815): Contingent Put and Call Options in Debt Instruments clarifies that in assessing whether an embedded contingent put or call option is clearly and closely related to the debt host, an entity is required to perform only the four-step decision sequence in ASC 815, as amended by the ASU. Accordingly, when a call (put) option is contingently exercisable, there is no requirement that an entity must assess whether the event that triggers the ability to exercise a call (put) option is related to interest rate or credit risk. CIT adopted this amendment as of January 1, 2017. The adoption did not result in a significant impact on the Company’s financial statements or disclosures.  ASU 2016-07, Investments—Equity method and joint ventures (Topic 323), Simplifying the Transition to the Equity Method of Accounting ; eliminates the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. For available ‐ for ‐ sale securities that become eligible for the equity method of accounting, any unrealized gain or loss recorded within accumulated other comprehensive income should be recognized in earnings at the date the investment initially qualifies for the use of the equity method. The new standard should be applied prospectively for investments that qualify for the equity method of accounting after the effective date. CIT adopted this amendment as of January 1, 2017. The adoption did not result in a significant impact on the Company’s financial statements or disclosures.  ASU 2016 ‐ 09: Compensation—Stock Compensation (Topic 718), simplifies several aspects of the accounting for share based payment award transactions to employees. The standard requires that all excess tax benefits and tax deficiencies that pertain to employee stock-based incentive payments be recognized within income tax expense in the consolidated statements of income, rather than within additional paid-in capital. When an employee’s shares are used to satisfy the employers’ statutory income tax withholding obligation, the threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdiction. The standard also allows an entity to make a Company-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. CIT adopted this Update as of January 1, 2017. The adoption did not result in a significant impact to CIT’s financial statement disclosures. CIT has changed its accounting policy to account for forfeitures as they occur in order to determine the amount of compensation cost to be recognized in each period. The Company also retrospectively applied the presentation requirements for cash flows related to employee taxes paid for withheld shares, resulting in a reclassification of $10.5 million from operating activities to financing activities for March 31, 2016 in the Company’s consolidated Statements of Cash Flows. ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323) amends certain SEC paragraphs to incorporate SEC staff announcements made at the September 22, 2016, and November 17, 2016, Emerging Issues Task Force meetings. ASU 2017-03 incorporates these SEC staff views into ASC 250 and adds references to that guidance in the transition paragraphs of each of the three new standards ASU 2014-09, Revenue from Contracts with Customers (Topic 606), ASU 2016-02, Leases (Topic 842), and ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument s relating to expanded disclosures under SAB 74, Topic 11.M. The ASU also conforms ASC 323-740-S99-2, which describes the SEC staff’s views on accounting for investments in qualified affordable housing projects, to the guidance issued in ASU 2014-01.  CIT adopted the guidance as it relates to Topic 250, Accounting Changes and Error Corrections, and ASC Topic 323, Investments—Equity Method and Joint Ventures as of January 1, 2017. The adoption did not result in a significant impact on the Company’s financial statements or disclosures. To the extent such corrections impact the three new standards, CIT plans to align the adoption of the update with the relevant adoption dates of these standards.  ASU 2017-04 , Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of the goodwill impairment test under current GAAP) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on today’s Step 1). The one-step impairment test will be applied to goodwill for all reporting units, even those with zero or negative carrying amounts. This guidance is required to be applied prospectively to transactions occurring within the period of adoption. CIT early adopted this standard as of January 1, 2017. The adoption did not result in any impact on the Company’s financial statements or disclosures.

Revenue Recognition The revenue recognition guidance (ASU 2014-09, ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-11, ASU 2016-12, ASU 2016-20) establishes the principles to apply to determine the amount and timing of revenue recognition, specifying the accounting for certain costs related to revenue, and requiring additional disclosures about the nature, amount, timing and uncertainty of revenues and related cash flows. The core principle is that a company will recognize revenue when it transfers control of goods or services to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The standard also changes the accounting for certain contract costs, including whether they may be offset against revenue in the Consolidated Statements of Income, and requires additional disclosures about revenue and contract costs. Companies can choose to apply the standard using either the full retrospective approach or a modified retrospective approach. Under the modified approach, financial statements will be prepared for the year of adoption using the new standard, but prior periods will not be adjusted. Instead, companies will recognize a cumulative catch-up adjustment to the opening balance of retained earnings at the effective date for contracts that still require performance by the company and disclose all line items in the year of adoption as if they were prepared under today’s revenue guidance. The required effective date is January 1, 2018.  The review and analysis of CIT’s individual revenue streams is currently underway. “Interest Income” and “Rental Income on Operating Leases”, CIT’s two largest revenue items, are scoped out of the new guidance; as are many other revenues relating to financial assets and liabilities, including loans, leases, securities and derivatives. As such, the majority of our revenues will not be impacted; however, certain ancillary revenues and components of “Other income” are being assessed at a contractual level pursuant to the new standard. We expect our accounting policies will not change materially.  CIT plans to adopt the standard in the first quarter of 2018 and expects to use the modified retrospective method (cumulative initial effect recognized at the date of adoption, with additional footnote disclosures). However, we are continuing to evaluate the impact of the standard, and our adoption method is subject to change. CIT does not anticipate a significant impact on our financial statements and disclosures upon adoption of the standard. Our evaluations are not final and we continue to assess the impact of the Update on our revenue contracts.  Leases ASU 2016-02, Leases was issued in February 2016, is intended to increase transparency and comparability of accounting for lease transactions, and will require all leases to be recognized on the balance sheet as lease assets and lease liabilities.  Lessor accounting remains similar to the current model, but updated to align with certain changes to the lessee model ( e.g., certain definitions, such as initial direct costs, have been updated) and the new revenue recognition standard. Lease classifications by lessors are similar, operating, direct financing, or sales-type.  Lessees will need to recognize all leases longer than twelve months on the Consolidated balance sheets as lease liabilities with corresponding right-of-use assets. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit thresholds. The ASU will require both quantitative and qualitative disclosures regarding key information about leasing arrangements.   The standard is effective for the Company on January 1, 2019. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented.  Although the new guidance does not significantly change lessor accounting, CIT will need to determine the impact to both, where it is a lessee and a lessor: · Lessor accounting: Given limited changes to Lessor accounting, we do not expect material changes to recognition or measurement. Current lease administration and/or reporting systems and processes will need to be evaluated and updated as required to ensure appropriate lease ‐ type identification and classification. · Lessee accounting: The new standard will result in virtually all leases being reflected on the balance sheet. The impact on lessee accounting also includes identification of any embedded leases included in service contracts that CIT has with vendors.  The Company is currently evaluating the effect of this ASU on its financial statements and disclosures. CIT management has assembled a project committee to assess the impact in order to implement and adopt the standard in the first quarter of 2019.  Credit Losses ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, introduces a forward-looking “expected loss” model (the “Current Expected Credit Losses” (“CECL”) model) to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale (“AFS”) debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The ASU replaces the existing incurred loss impairment guidance and establishes a single allowance framework for financial assets carried at amortized cost (including held to maturity (“HTM”) securities), which will reflect management’s estimate of credit losses over the full remaining expected life of the financial assets. It eliminates existing guidance for purchase credit impaired (“PCI”) loans, and requires recognition of an allowance for expected credit losses on financial assets purchased with more than insignificant credit deterioration since origination. In addition, it amends existing impairment guidance for AFS securities to incorporate an allowance, which will allow for reversals of impairment losses in the event that the credit of an issuer improves. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted (modified-retrospective approach). A prospective transition approach is required for debt securities for which an other than temporary impaired (“OTTI”) had been recognized before the effective date. A prospective transition approach should be used for purchased with more than insignificant credit deterioration (“PCD”) assets where upon adoption; the amortized cost basis should be adjusted to reflect the addition of the allowance for credit losses.  The ASU will be effective January 1, 2020. Early adoption of the guidance will be permitted for all entities for fiscal years beginning January 1, 2019. CIT is currently evaluating the effect of this ASU on its financial statements and disclosures.  The following accounting pronouncements have been issued by the FASB during the first quarter of 2017 but are not yet effective:  · ASU 2017-01 , Business Combinations (Topic 805): Clarifying the Definition of a Business; · ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets; · ASU 2017-07, Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost; · ASU 2017-08 , Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.  In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This guidance narrows the definition of a business. This standard provides guidance to assist entities with evaluating when a set of transferred assets and activities is a business. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted. This guidance must be applied prospectively to transactions occurring within the period of adoption. CIT expects to adopt this guidance effective January 1, 2018. The Company is currently evaluating the impact of this ASU.  In February 2017, FASB issued ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets. This guidance clarifies the scope of accounting for derecognition or partial sale of nonfinancial assets to exclude all businesses and non-profit activities. ASU 2017-05 also provides a definition for in substance non-financial assets and additional guidance on partial sales of non-financial assets. The amendments are effective at the same time Topic 606, Revenue from Contracts with Customers , is effective. For public entities, they are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of this ASU on its financial statements and disclosures and plans to adopt in conjunction with the revenue recognition standard described earlier in the first quarter of 2018.  In March 2017, FASB issued the ASU 2017-07 - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost to improve the reporting of net periodic benefit cost from defined benefit pension plans and other postretirement benefit plans in the financial statements of all employers. The ASU amends ASC 715, Compensation — Retirement Benefits, to require employers that present a measure of operating income in their statement of income to include only the service cost component of net periodic pension cost and net periodic postretirement benefit cost in operating expenses (together with other employee compensation costs). The other components of net benefit cost, including amortization of prior service cost/credit, and settlement and curtailment effects, are to be included in non- operating expenses. Employers that do not present a measure of operating income are required to include the service cost component in the same line item as other employee compensation costs. Employers are required to include all other components of net benefit cost in a separate line item(s). The line item(s) in which the components of net benefit cost other than the service cost are included needs to be identified as such on the income statement or in the disclosures. The ASU also stipulates that only the service cost component of net benefit cost is eligible for capitalization.  This is applicable for public entities after December 15, 2017, including interim periods within those periods. Early adoption is permitted as of the beginning of an annual period for which financial statements have not yet been issued or made available for issuance. The amendments related to presentation of service cost and other components in the income statements must be applied retrospectively to all periods presented. The amendments related to the capitalization of the service cost component should be applied prospectively, on and after the date of adoption. The Company is currently evaluating the impact of this ASU on its financial statements and disclosures and does not intend to early adopt this standard. The purpose of ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities is to amend the amortization period for purchased callable debt securities held at a premium by shortening the amortization period to the earliest call date. Current guidance does not allow for the recognition of an early repayment of principal even if there is a high degree of certainty that the call will be exercised. As a result a loss in earnings must be recognized when the call is exercised at a premium. This accounting change does not impact securities held at a discount. For public business entities the effective date for this ASU is for fiscal years, and the interim periods with in those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact of this ASU on its financial statements and disclosures and does not intend to early adopt this standard.

As discussed in subsequent tables, since the Company manages the credit risk and collections of finance receivables held for sale consistently with its finance receivables held for investment, the aggregate amount is presented in this table. The following table presents finance receivables, excluding assets held for sale, by segment, based on obligor location:  Finance Receivables (dollars in millions)      March 31, 2017 December 31, 2016  Domestic Foreign Total Domestic Foreign Total  Commercial Banking $ 20,897.0 $ 1,981.6 $ 22,878.6 $ 20,440.7 $ 2,121.6 $ 22,562.3  Consumer Banking (1) 6,812.8 – 6,812.8 6,973.6 – 6,973.6  Total $ 27,709.8 $ 1,981.6 $ 29,691.4 $ 27,414.3 $ 2,121.6 $ 29,535.9  (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 balance and included in the Commercial loan balances in the tables throughout this note.

Certain of the following tables present credit-related information at the “class” level in accordance with ASC 310-10-50, Disclosures about the Credit Quality of Finance Receivables and the Allowance for Credit Losses . A class is generally a disaggregation of a portfolio segment. In determining the classes, CIT considered the finance receivable characteristics and methods it applies in monitoring and assessing credit risk and performance. Credit Quality Information Commercial obligor risk ratings are reviewed on a regular basis by Credit Risk Management and are adjusted as necessary for updated information affecting the borrowers’ ability to fulfill their obligations. The following table summarizes commercial finance receivables 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.

LTV refers to the ratio comparing the loan’s unpaid principal balance to the property’s collateral value. We examine LTV migration and stratify LTV into categories to monitor the risk in the loan classes. 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 finance receivables are “covered loans” for which the Company can be reimbursed for a substantial portion of future losses under the terms of loss sharing agreements with the FDIC if losses occur within the indemnification period. As of March 31, 2017 and December 31, 2016, the carrying value of the indemnification asset for covered single family residential and reverse mortgage loans totaled $207 million and $233 million, respectively, under the IndyMac Transaction. No indemnification asset was recognized in connection with the First Federal or La Jolla Transaction. The indemnification asset is measured on the same basis of accounting as the covered loans (e.g., as PCI loans under the effective yield method). Covered loans are further discussed in our Form 10-K for the year ended December 31, 2016, Note 5- Indemnification Assets . Covered loans are limited to the Consumer Banking LCM division .

Payments received on non-accrual financing receivables are generally applied first against outstanding principal, though in certain instances where the remaining recorded investment is deemed fully collectible, interest income is recognized on a cash basis. Reverse mortgages are not included in the non-accrual balances.

Small-ticket loan and lease receivables that have not been modified in a restructuring are included (if appropriate) in the reported non-accrual balances above, but are excluded from the impaired finance receivables disclosure below as charge-offs are typically determined and recorded for such loans when they are more than 90- 150 days past due.

Loans Acquired with Deteriorated Credit Quality For purposes of this presentation, the Company is applying the income recognition and disclosure guidance in ASC 310-30 ( Loans and Debt Securities Acquired with Deteriorated Credit Quality ) to loans that were identified as impaired as of the Acquisition Date. PCI loans were initially recorded at estimated fair value with no allowance for loan losses carried over, since the initial fair values reflected credit losses expected to be incurred over the remaining lives of the loans. The acquired loans are subject to the Company’s internal credit review. See Note 4 — Allowance for Loan Losses.

Criticized loans are risk rated as special mention or classified.  Accretable Yield The excess of cash flows expected to be collected over the recorded investment (estimated fair value at acquisition) of the PCI loans represents the accretable yield and is recognized in interest income on an effective yield basis over the remaining life of the loan, or pools of loans. The accretable yield is adjusted for changes in interest rate indices for variable rate PCI loans, changes in prepayment assumptions and changes in expected principal and interest payments and collateral values. Further, if a loan within a pool of loans is modified, the modified loan remains part of the pool of loans. The difference between the cash flows contractually required to be paid, measured as of the Acquisition Date, over the expected cash flows is referred to as the non-accretable difference. Subsequent to acquisition, we evaluate our estimates of the cash flows expected to be collected on a quarterly basis. Probable and significant decreases in expected cash flows as a result of further credit deterioration result in a charge to the provision for credit losses and a corresponding increase to the allowance for credit losses. Probable and significant increases in expected cash flows due to improved credit quality result in reversal of any previously recorded allowance for loan losses, to the extent applicable, and an increase in the accretable yield applied prospectively for any remaining increase. Changes in expected cash flows caused by changes in market interest rates or by prepayments are recognized as adjustments to the accretable yield on a prospective basis. Changes in the accretable yield for PCI loans are summarized below for the quarters ended March 31, 2017 and March 31, 2016.

Modifications that include a financial concession to the borrower are accounted for as troubled debt restructurings (TDRs).  Modified loans that meet the definition of a TDR are subject to the Company’s standard impaired loan policy, namely that non-accrual loans in excess of $500,000 are individually reviewed for impairment, while non-accrual loans less than $500,000 are considered as part of homogenous pools and are included in the determination of the non-specific allowance.  We may require some consumer borrowers experiencing financial difficulty to make trial payments generally for a period of three to four months, according to the terms of a planned permanent modification, to determine if they can perform according to those terms. These arrangements represent trial modifications, which we classify and account for as TDRs. While loans are in trial payment programs, their original terms are not considered modified and they continue to advance through delinquency status and accrue interest according to their original terms. The planned modifications for these arrangements predominantly involve interest rate reductions or other interest rate concessions; however, the exact concession type and resulting financial effect are usually not finalized and do not take effect until the loan is permanently modified. The trial period terms are developed in accordance with our proprietary programs or the U.S. Treasury’s Making Homes Affordable (“MHA”) programs for real estate 1-4 family first lien ( i.e., Home Affordable Modification Program – HAMP) and junior lien (i.e., Second Lien Modification Program – 2MP) mortgage loans. HAMP and other MHA programs expired on December 31, 2016 (the last day to submit an application).  At March 31, 2017, the loans in trial modification period were $20.1 million under HAMP, $0.2 million under 2MP and $8.9 million under proprietary programs. Trial modifications with a recorded investment of $27.4 million at March 31, 2017 were accruing loans and $1.8 million were non-accruing loans. At December 31, 2016, the loans in trial modification period were $36.4 million under HAMP, $0.1 million under 2MP and $3.0 million under proprietary programs. Trial modifications with a recorded investment of $38.1 million at December 31, 2016 were accruing loans and $1.4 million were non-accruing loans. Our experience is that substantially all of the mortgages that enter a trial payment period program are successful in completing the program requirements and are then permanently modified at the end of the trial period. Our allowance process considers the impact of those modifications that are probable to occur.  The recorded investment of TDRs, excluding those classified as PCI and those within a trial modification period discussed in the preceding paragraph, at March 31, 2017 and December 31, 2016 was $114.1 million and $82.3 million, of which 53% and 41% , respectively, were on non-accrual. See the preceding paragraph on discussion related to TDRs in trial modification period. Commercial Banking and Consumer Banking receivables accounted for 88% a nd 12% of the total TDRs, respectively, at March 31, 2017. Commercial Banking and Consumer Banking receivables accounted for 85% and 15% of the total TDRs, respectively at December 31, 2016. There were $4.8 million and $5.4 million as of March 31, 2017 and December 31, 2016, 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 March 31, 2017 and 2016 were $34.1 million and $16.1 m illion, respectively. The recorded investment as of March 31, 2017 and 2016 of TDRs that experience a payment default (payment default is one missed payment), during the quarters ended March 31, 2017 and 2016, and for which the payment default occurred within one year of the modification totaled $1.2 million and $5.9 million, respectively. The defaults that occurred during the current quarter and year to date related to Commercial Banking and Consumer Banking. 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 2017 amounts, the overall nature and impact of modification programs were comparable in the prior year.   • The nature of modifications qualifying as TDR’s based upon recorded investment at March 31, 2017 was com prised of payment deferrals for 38% and covenant relief and/or other for 62% . December 31, 2016 TDR recorded investment was comprised of payment deferrals for 1 2% and covenant relief and/or other for 88% .   • 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. Additionally, in some instances, modifications improve the Company’s economic return through increased interest rates and fees, but are reported as TDRs due to assessments regarding the borrowers’ ability to independently obtain similar funding in the market and assessments of the relationship between modified rates and terms and comparable market rates and terms. The weighted average change in interest rates for all TDRs occurring during the quarters ended March 31, 2017 and 2016 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 March 31, 2017 and 2016 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. Reverse Mortgages Consumer loans within continuing operations include an outstanding balance of $ 858.7 million and $858.9 million at March 31, 2017 and December 31, 2016, respectively, related to the reverse mortgage portfolio, of which $7 68.3 million and $ 769.6 million at March 31, 2017 and December 31, 2016, respectively, was uninsured. The uninsured reverse mortgage portfolio consists of approximately 1, 700 loans with an average borrowers’ age of 83 years old and an unpaid principal balance of $1,018.4 million at March 31, 2017. At December 31, 2016, the uninsured reverse mortgage portfolio consisted of approximately 1,700 loans with an average borrowers’ age of 83 years old and an unpaid principal balance of $1,027.9 million. The realizable collateral value (the lower of the collectible principal and interest or the estimated value of the home ) exceeds the outstanding book balance at March 31, 2017 and December 31, 2016.  As of March 31, 2017, the Company’s estimated future advances to reverse mortgagors are as follows: Future Advances (dollars in millions)      Year Ending:   2017 $ 11.3  2018 11.4  2019 9.4  2020 7.8  2021 6.4  Years 2022 - 2026 17.4  Years 2027 - 2031 5.3  Years 2032 - 2036 1.4  Thereafter 0.3  Total (1), (2) $ 70.7  (1) This table does not take into consideration cash inflows including payments from mortgagors or payoffs based on contractual terms. (2) This table includes the reverse mortgages supported by the Company as a result of the IndyMac loss-share agreements with the FDIC. As of March 31, 2017, the Company is responsible for funding up to a remaining $57 million of the total amount.  Serviced Loans As a result of the OneWest Transaction, the Company services Home Equity Conversion Mortgages (“HECM”) reverse mortgage loans sold to Agencies (Fannie Mae) and securitized into GNMA HECM mortgage-backed securities (“ HMBS ”) pools. HECM loans transferred into the HMBS program have not met all the requirements for sale accounting, and therefore, the Company has accounted for these transfers as a financing transaction with the loans remaining on the Company’s statement of financial position and the proceeds received are recorded as a secured borrowing. The pledged loans and secured borrowings are reported in Assets of discontinued operations and Liabilities of discontinued operations, respectively. See Note 2 – Discontinued Operations . As servicer of HECM loans, the Company is required to repurchase loans out of the HMBS pool upon completion of foreclosure or once the outstanding principal balance is equal to or greater than 98% of the maximum claim amount. Although permitted under the GNMA HMBS program, the Company does not conduct optional repurchases upon the loan reaching a maturity event (i.e., borrower’s death or the property ceases to be the borrower’s principal residence). These HECM loans are repurchased at a price equal to the unpaid principal balance outstanding on the loan plus accrued interest. The repurchase transaction represents extinguishment of debt. As a result, the HECM loan basis and accounting methodology (retrospective effective interest) would carry forward. However, if the Company classifies these repurchased loans as assets held for sale (“ AHFS ”) , that classification would result in a new accounting methodology. Loans classified as AHFS are carried at lower of cost or market (“ LOCOM ”) pending assignment to the Department of Housing and Urban Development (“HUD”). Loans classified as HFI are not assignable to HUD and are subject to periodic impairment assessment. In the quarter ended March 31, 2017, the Company repurchased $27.9 million (unpaid principal balance) of additional HECM loans, of which $21.8 million were classified as AHFS and the remaining $6.1 million were classified as HFI. As of March 31, 2017, the Company had an outstanding balance of $131.7 million of HECM loans, of which $41.5 million (unpaid principal balance) is classified as AHFS with a remaining purchase discount of $0.1 million and $65.3 million is classified as HFI accounted for as PCI loans with an associated remaining purchase discount of $8.4 million. Serviced loans also include $33.5 million that are classified as HFI, which are accounted for under the effective yield method, with no remaining purchase discount. As of December 31, 2016, the Company had an outstanding balance of $122.2 million of HECM loans, of which $32.8 million (unpaid principal balance) were classified as AHFS with a remaining purchase discount of $0.1 million, $68.1 million were classified as HFI accounted for as PCI loans with an associated remaining purchase discount of $9.1 million. Serviced loans also included $30.4 million that were classified as HFI, accounted for under the effective yield method and have no remaining purchase discount.

Allowance For Loan Losses [Abstract]
Allowance For Loan Losses	NOTE 4 — ALLOWANCE FOR LOAN LOSSES The Company maintains an allowance for loan losses for estimated credit losses in its HFI loan portfolio. The allowance is adjusted through a provision for credit losses, which is charged against current period earnings, and reduced by any charge-offs for losses, net of recoveries. The Company maintains a separate reserve for credit losses on off-balance sheet commitments, which is reported in Other Liabilities.

FHLB Advances As a member of the FHLB of San Francisco, CIT Bank, N.A. can access financing based on an evaluation of its creditworthiness, statement of financial position, size and eligibility of collateral. The interest rates charged by the FHLB for advances typically vary depending upon maturity, the cost of funds of the FHLB, and the collateral provided for the borrowing and the advances are secured by certain Bank assets and bear either a fixed or floating interest rate. The FHLB advances are collateralized by a variety of consumer and commercial loans and leases, including SFR mortgage loans, reverse mortgage loans, multi-family mortgage loans, commercial real estate loans, certain foreclosed properties and certain amounts receivable under a loss sharing agreement with the FDIC, commercial loans, leases and/or equipment. As of March 31, 2017, the Company had $5.2 billion of financing availability with the FHLB, of which $2.0 billion was unused and available, and $865.4 million was being utilized for issuance of letters of credit related to deposits .

See Note 2 – Discontinued Operations . FRB The Company has a borrowing facility with the FRB Discount Window that can be used for short-term, typically overnight, borrowings. The borrowing capacity is determined by the FRB based on the collateral pledged.  There were no outstanding borrowings with the FRB Discount Window as of March 31, 2017 and December 31, 2016.  Variable Interest Entities (“VIEs”) Below describes the results of the Company’s assessment of its variable interests to determine its current status with regards to being the primary beneficiary of a VIE. 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. See the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 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 where 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. As a result of the OneWest Transaction, the Company has certain contractual obligations related to the HECM loans and the GNMA HMBS securitizations. The Company, as servicer of these HECM loans, is currently 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 capitalizes the servicing fees and interest income earned and is obligated to fund guarantee fees associated with the GNMA HMBS. The Company periodically pools and securitizes certain of these funded advances through issuance of HMBS to third-party security holders, which did not qualify for sale accounting and rather, are treated as financing transactions. As a financing transaction, the HECM loans and related proceeds from the issuance of the HMBS recognized as secured borrowings remain on the Company’s Consolidated Balance Sheet . Due to the Company’s planned exit of third party servicing, HECM loans of $352.8 million and $37 4.0 million were included in Assets of discontinued operations and the associated secured borrowing of $345.4 m illion and $366. 4 million (including an unamortized premium balance of $7.1 m illion and $8.1 million) were included in Liabilities of discontinued operations at March 31, 2017 and December 31, 2016, respectively. As servicer, 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 $154.2 million and $160.2 million of HMBS outstanding principal balance at March 31, 2017 and December 31, 2016, 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 March 31, 2017 and December 31, 2016. 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 or quantifiable. 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 at the same time assuming no consideration of 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.

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	NOTE 7 — DERIVATIVE FINANCIAL INSTRUMENTS  As part of managing economic risk and exposure to interest rate and foreign currency risk, the Company primarily enters into derivative transactions in over-the-counter markets with other financial institutions. The Company does not enter into derivative financial instruments for proprietary trading or speculative purposes.  See Note 1 — Business and Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 for further description of its derivative transaction policies.  The following table presents fair values and notional values of derivative financial instruments: Fair and Notional Values of Derivative Financial Instruments (1) (dollars in millions)      March 31, 2017 December 31, 2016  Notional Asset Liability Notional Asset Liability  Qualifying Hedges Amount Fair Value Fair Value Amount Fair Value Fair Value  Foreign currency forward contracts – net investment hedges $ 924.6 $ 8.3 $ (0.8) $ 817.9 $ 16.9 $ –  Total Qualifying Hedges 924.6 8.3 (0.8) 817.9 16.9 –  Non-Qualifying Hedges  Interest rate swaps (2) 5,862.7 58.8 (32.9) 5,309.2 63.0 (50.1)  Written options 2,663.1 – (0.9) 2,626.5 0.1 (1.0)  Purchased options 2,332.5 0.9 – 2,129.6 1.0 (0.1)  Foreign currency forward contracts 1,338.5 7.6 (5.9) 1,329.8 30.2 (6.0)  Total Return Swap (TRS) 158.0 – (12.2) 587.5 – (11.3)  Equity Warrants 1.0 0.1 – 1.0 0.2 –  Interest Rate Lock Commitments 8.7 0.1 – 20.7 0.1 (0.1)  Forward Sale Commitments on Agency MBS 20.0 – (0.2) 39.0 0.1 –  Credit derivatives 266.6 – (0.1) 267.6 – (0.2)  Total Non-qualifying Hedges 12,651.1 67.5 (52.2) 12,310.9 94.7 (68.8)  Total Hedges $ 13,575.7 $ 75.8 $ (53.0) $ 13,128.8 $ 111.6 $ (68.8)     (1) Presented on a gross basis . (2) Fair value balances include accrued interest.  TRS Transactions As of December 31, 2016, CIT was party to two financing facilities between two wholly-owned subsidiaries of CIT, one Canadian (“CFL”) and one Dutch, and Goldman Sachs International (“GSI”), respectively, which were structured as total return swaps (“TRS”). Amounts available for advances (otherwise known as the unused portion) were accounted for as derivatives and recorded at the estimated fair value. On December 7, 2016, CFL entered into a Fourth Amended and Restated Confirmation (the “Termination Agreement”) with GSI to terminate the Canadian TRS and the facility was terminated on January 17, 2017 . The total facility capacity available under the Dutch TRS was $625 million at March 31, 2017 and December 31, 2016. The utilized portion reflects the borrowing. The aggregate “notional amount s” of the Dutch TRS of $158.0 million at March 31, 2017 and the TRS Transactions of $587.5 million at December 31, 2016 represent the aggregate unused portions and constitute derivative financial instruments. These notional amounts were calculated as the maximum facility commitment amount , $625 million, under the Dutch TRS less the actual adjusted qualifying borrowing base outstanding of $467.0 million under the facility at March 31, 2017 , and the maximum aggregate facility commitment amount, $1,062.3 million, under the Canadian TRS and Dutch TRS less the aggregate actual adjusted qualifying borrowing base outstanding of $474.8 million under the facilities at December 31, 2016 . The notional amounts of the derivative will increase as the adjusted qualifying borrowing base decreases due to repayment of the underlying ABS to investors. If CIT funds additional ABS under the Dutch TRS, the aggregate adjusted qualifying borrowing base of the total return swaps will increase and the notional amount of the derivatives will decrease accordingly. Based on the Company’s valuation, a liability of $12.2 million and $11.3 million was recorded at March 31, 2017 and December 31, 2016, respectively. The increase in liability of $0.9 million was recognized as a decrease to Other Income for the quarter ended March 31, 2017. The decrease in the liability of $18.2 million was recognized as an increase to Other Income for the quarter ended March 31, 2016.  Impact of Collateral and Netting Arrangements on the Total Derivative Portfolio  The following tables present a summary of our derivative portfolio, which includes the gross amounts of recognized financial assets and liabilities; the amounts offset in the consolidated balance sheet; the net amounts presented in the consolidated balance sheet; the amounts subject to an enforceable master netting arrangement or similar agreement that were not included in the offset amount above, and the amount of cash collateral received or pledged. Derivative transactions are documented under an International Swaps and Derivatives Association (“ISDA”) agreement.  Offsetting of Derivative Assets and Liabilities (dollars in millions) (1)       Gross Amounts not offset in the Consolidated Balance Sheet  Gross Amount of Recognized Assets (Liabilities) Gross Amount Offset in the Consolidated Balance Sheet Net Amount Presented in the Consolidated Balance Sheet Derivative Financial Instruments (2) Cash Collateral Pledged/ (Received) (2)(3) Net Amount  March 31, 2017  Derivative assets $ 75.8 $ – $ 75.8 $ (14.3) $ (14.5) $ 47.0  Derivative liabilities (53.0) – (53.0) 14.3 2.9 (35.8)   December 31, 2016  Derivative assets $ 111.6 $ – $ 111.6 $ (30.9) $ (48.7) $ 32.0  Derivative liabilities (68.8) – (68.8) 30.9 5.0 (32.9)  (1) Due to a change in clearinghouse rules, the Company accounts for swap contracts cleared by the Chicago Mercantile Exchange ("CME') 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 ("LCH") continue to be accounted for as "collateralized-to-market" and variation margin balances are characterized as collater al against derivative exposures At March 31, 2017, gross amount of recognized assets and liabilities were lower by $5.1 million and $16.7 million, respectively. (2) 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 (“Derivative Financial Instruments”) 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 . (3) Collateral pledged or received is included in Other assets or Other liabilities, respectively.

Fair Value [Abstract]
Fair Value	NOTE 8 — FAIR VALUE Fair Value Hierarchy The Company is required to report fair value measurements for specified classes of assets and liabilities. See Note 1 — “Business and Summary of Significant Accounting Policies” for a description of fair value measurement policy. The Company characterizes inputs in the determination of fair value according to the fair value hierarchy. The fair value of the Company’s assets and liabilities where the measurement objective specifically requires the use of fair value are set forth in the tables below.  Disclosures that follow in this note exclude assets and liabilities classified as discontinued operations.  Financial Assets and Liabilities Measured at Estimated Fair Value on a Recurring Basis The following table summarizes the Company’s assets and liabilities measured at estimated fair value on a recurring basis, including those management elected under the fair value option.      March 31, 2017 Total Level 1 Level 2 Level 3  Assets  Debt Securities AFS $ 3,696.8 $ – $ 3,226.3 $ 470.5  Securities carried at fair value with changes recorded in net income 268.9 – – 268.9  Equity Securities AFS 34.2 0.2 34.0 –  Derivative assets at fair value -non-qualifying hedges (1) 67.5 – 67.4 0.1  Derivative assets at fair value - qualifying hedges 8.3 – 8.3 –  Total $ 4,075.7 $ 0.2 $ 3,336.0 $ 739.5  Liabilities  Derivative liabilities at fair value - non-qualifying hedges (1) $ (52.2) $ – $ (39.9) $ (12.3)  Derivative liabilities at fair value - qualifying hedges (0.8) – (0.8) –  Consideration holdback liability (47.4) – – (47.4)  FDIC True-up Liability (63.0) – – (63.0)  Total $ (163.4) $ – $ (40.7) $ (122.7)  December 31, 2016  Assets  Debt Securities AFS $ 3,674.1 $ 200.1 $ 2,988.5 $ 485.5  Securities carried at fair value with changes recorded in net income 283.5 – – 283.5  Equity Securities AFS (2) 34.1 0.3 33.8 –  Derivative assets at fair value -non-qualifying hedges (1) 94.7 – 94.7 –  Derivative assets at fair value - qualifying hedges 16.9 – 16.9 –  Total $ 4,103.3 $ 200.4 $ 3,133.9 $ 769.0  Liabilities  Derivative liabilities at fair value - non-qualifying hedges (1) $ (68.8) $ – $ (57.3) $ (11.5)  Consideration holdback liability (47.2) – – (47.2)  FDIC True-up Liability (61.9) – – (61.9)  Total $ (177.9) $ – $ (57.3) $ (120.6)  (1) Derivative fair values include accrued interest Debt and Equity Securities Classified as AFS and Securities carried at fair value with changes recorded in net income - Debt and equity securities classified as AFS are carried at fair value, as determined either by Level 1, L evel 2 or Level 3 inputs. Debt securities classified as AFS included investments in U.S. federal government agency , U.S. Treasury Notes and supranational securities and were valued using Level 2 inputs, primarily quoted prices for similar securities. U.S. Treasury Bills and certain equity securities classified as AFS were valued using Level 1 inputs, primarily quoted prices in active markets . For Agency pass-through MBS, which are classified as Level 2, the Company generally determines estimated fair value utilizing prices obtained from independent broker dealers and recent trading activity for similar assets. Debt securities classified as AFS and securities carried at fair value with changes recorded in net income represent non-Agency MBS, the market for such securities is not active and the estimated fair value was determined using a discounted cash flow technique. The significant unobservable assumptions, which are verified to the extent possible using broker dealer quotes, are estimated by type of underlying collateral, including credit loss assumptions, estimated prepayment speeds and appropriate discount rates. Given the lack of observable market data, the estimated fair value of the non-agency MBS is classified as Level 3. Derivative Assets and Liabilities —The Company’s financial derivatives include interest rate swaps, floors, caps, forwards , forward sale commitments on Agency MBS and credit derivatives. These derivatives are valued using models that incorporate inputs depending on the type of derivative, such as interest rate curves, foreign exchange rates and volatility. Readily observable market inputs to models can be validated to external sources, including industry pricing services, or corroborated through recent trades, broker dealer quotes, yield curves, or other market-related data. As such, these derivative instruments are valued using a Level 2 methodology. In addition, these derivative values incorporate an assessment of the risk of counterparty nonperformance, measured based on the Company’s evaluation of credit risk. The fair value of the TRS derivative, written options on certain CIT Bank CDs and credit derivatives were estimated using Level 3 inputs. FDIC True-up Liability — In connection with the La Jolla Transaction, the Company recognized a FDIC True-up liability due to the FDIC 45 days after the tenth anniversary of the loss shar e agreement (the maturity) because the actual and estimated cumulative losses on the acquired covered PCI loans are lower than the cumulative losses originally estimated by the FDIC at the time of acquisition. The FDIC True-up liability was recorded at estimated fair value as of the Acquisition D ate and is remeasured to fair value at each reporting date until the contingency is resolved. The FDIC True-up liability was valued using the discounted cash flow method based on the terms specified in the loss shar e agreement with the FDIC, the actual FDIC payments collected and significant unobservable inputs, including a risk-adjusted discount rate (reflecting the Company’s credit risk plus a liquidity premium), prepayment and default rates. Due to the significant unobservable inputs used to calculate the estimated fair value, these measurements are classified as Level 3. Consideration Holdback Liability — In connection with the OneWest acquisition, the parties negotiated 4 separate holdbacks related to select ed trailing risks, totaling $116 million , which reduced the cash consideration paid at closing. Any unapplied Holdback funds at the end of the respective holdback periods, which range from 1 – 5 years, are payable to the former OneWest shareholders. Unused funds for any of the four holdbacks cannot be applied against another holdback amount. The range of potential holdback to be paid is from $0 to $116 million. Based on management’s estimate of the probability of each holdback it was determined that the probable amount of holdback to be paid was originally recorded at $62.4 mil lion, and currently is $47.4 million. The amount expected to be paid was discounted based on CIT’s cost of funds, which approximates a market rate. This contingent consideration was measured at fair value at the Acquisition D ate and is re-measured at fair value in subsequent accounting periods, with the changes in fair value recorded in the statement of income, until the related contingent issues are resolved. Gross payments, which are determined based on the Company’s probability assessment, are discounted at a rate approximating the Company’s aver age coupon rate on deposits and borrowings. Due to the significant unobservable inputs used to calculate the estimated fair value, these measurements are 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 March 31, 2017 and December 31, 2016 .

The level of aggregation and diversity within the products disclosed in the tables results in certain ranges of inputs being wide and unevenly distributed across asset and liability categories. For instruments backed by residential real estate, diversity in the portfolio is reflected in a wide range for loss severity due to varying levels of default. The lower end of the range represents high performing loans with a low probability of default while the higher end of the range relates to more distressed loans with a greater risk of default. The valuation techniques used for the Company’s Level 3 assets and liabilities, as presented in the previous tables, are described as follows: • Discounted cash flow —Discounted cash flow valuation techniques generally consist of developing an estimate of future cash flows that are expected to occur over the life of an instrument and then discounting those cash flows at a rate of return that results in the estimated fair value amount. The Company utilizes both the direct and indirect valuation methods. Under the direct method, contractual cash flows are adjusted for expected losses. The adjusted cash flows are discounted at a rate which considers other costs and risks, such as market risk and liquidity. Under the indirect method, contractual cash flows are discounted at a rate which reflects the costs and risks associated with the likelihood of generating the contractual cash flows. • Market comparables —Market comparable(s) pricing valuation techniques are used to determine the estimated fair value of certain instruments by incorporating known inputs such as recent transaction prices, pending transactions, or prices of other similar investments which require significant adjustment to reflect differences in instrument characteristics. " Internal valuation model – The internal model for rate lock valuation uses the spread on borrower mortgage rate and the Fannie Mae pass through rate and applies a conversion factor to assess the derivative value. Significant unobservable inputs presented in the previous tables are those the Company considers significant to the estimated fair value of the Level 3 asset or liability. The Company considers unobservable inputs to be significant if, by their exclusion, the estimated fair value of the Level 3 asset or liability would be significantly impacted based on qualitative factors such as nature of the instrument, type of valuation technique used, and the significance of the unobservable inputs on the values relative to other inputs used within the valuation. Following is a description of the significant unobservable inputs provided in the tables. • Default rate —is an estimate of the likelihood of not collecting contractual amounts owed expressed as a constant default rate. • Discount rate —is a rate of return used to present value the future expected cash flows to arrive at the estimated fair value of an instrument. The discount rate consists of a benchmark rate component and a risk premium component. The benchmark rate component, for example, LIBOR or U.S. Treasury rates, is generally observable within the market and is necessary to appropriately reflect the time value of money. The risk premium component reflects the amount of compensation market participants require due to the uncertainty inherent in the instruments’ cash flows resulting from risks such as credit and liquidity. • Loss severity —is the percentage of contractual cash flows lost in the event of a default. • Prepayment rate —is the estimated rate at which forecasted prepayments of principal of the related loan or debt instrument are expected to occur, expressed as a constant prepayment rate (“CPR”). " Payment Probability – is an estimate of the likelihood the consideration holdback amount will be required to be paid expressed as a percentage. " Borrower rate – Mortgage rate committed to the borrower by CIT Bank. Effective for up to 90 days. As reflected above, the Company generally uses discounted cash flow technique s to determine the estimated fair value of Level 3 assets and liabilities. Use of these techniques requires determination of relevant inputs and assumptions, some of which represent significant unobservable inputs and assumptions and as a result, changes in these unobservable inputs (in isolation) may have a significant impact to the estimated fair value. Increases in the probability of default and loss severities will result in lower estimated fair values, as these increases reduce expected cash flows. Increases in the discount rate will result in lower estimated fair values, as these increases reduce the present value of the expected cash flows. Alternatively a change in one unobservable input may result in a change to another unobservable input due to the interrelationship among inputs, which may counteract or magnify the estimated fair value impact from period to period. Generally, the value of the Level 3 assets and liabilities estimated using a discounted cash flow technique would decrease (increase) upon an increase (decrease) in discount rate, default rate, loss severity or weighted average life inputs. Discount rates are influenced by market expectations for the underlying collateral performance, and therefore may directionally move with probability and severity of default; however, discount rates are also impacted by broader market forces, such as competing investment yields, sector liquidity, economic news, and other macroeconomic factors. There is no direct interrelationship between prepayments and discount rate. Prepayment rates generally move in the opposite direction of market interest rates. Increase in the probability of default will generally be accompanied with an increase in loss severity, as both are impacted by underlying collateral values.  The following table summarizes the changes in estimated fair value for all assets and liabilities measured at estimated fair value on a recurring basis using significant unobservable inputs (Level 3):  Changes in Estimated Fair Value of Level 3 Financial Assets and Liabilities Measured on a Recurring Basis (dollars in millions)       Securities- AFS Securities carried at fair value with changes recorded in net income FDIC Receivable Derivative assets - non qualifying (1) Derivative liabilities - non-qualifying (2) FDIC True-up Liability Consideration holdback Liability  December 31, 2016 $ 485.5 $ 283.5 $ 0.6 $ – $ (11.5) $ (61.9) $ (47.2)  Included in earnings (1.7) 3.2 0.8 0.1 (0.8) (1.1) (0.2)  Included in comprehensive income 6.9 – – – – – –  Impairment (0.1) – – – – – –  Settlements (20.1) (17.8) – – – – –  Balance as of March 31, 2017 $ 470.5 $ 268.9 $ 1.4 $ 0.1 $ (12.3) $ (63.0) $ (47.4)  December 31, 2015 $ 567.1 $ 339.7 $ 54.8 $ – $ (55.5) $ (56.9) $ (60.8)  Included in earnings (1.5) (1.0) 2.8 0.2 18.5 (1.1) (0.6)  Included in comprehensive income (2.1) – – – – – –  Impairment (2.0) – – – – – –  Settlements (20.9) (15.7) (3.2) – – – –  Balance as of March 31, 2016 $ 540.6 $ 323.0 $ 54.4 $ 0.2 $ (37.0) $ (58.0) $ (61.4)   (1) Valuation of Interest Rate Lock Commitments (2) Valuation of the derivatives related to the TRS Transactions and written options on certain CIT Bank CDs.  The Company monitors the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in the observability of key inputs to a fair value measurement may result in a transfer of assets or liabilities between Level 1, 2 and 3. The Company’s policy is to recognize transfers in and transfers out as of the end of the reporting period. For the quarter s ended March 31, 2017 and 201 6 , there were no transfers into or out of Level 3. 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 nonrecurring basis subsequent to initial recognition. Generally, these adjustments are the result of LOCOM or other impairment accounting. In determining the estimated fair values during the period, 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 Level at Reporting Date  Total Carrying Value Level 1 Level 2 Level 3 Total (Losses)  Assets  March 31, 2017  Assets held for sale $ 162.5 $ – $ – $ 162.5 $ (1.7)  Other real estate owned 13.6 – – 13.6 (0.7)  Impaired loans 65.1 – – 65.1 (20.7)  Total $ 241.2 $ – $ – $ 241.2 $ (23.1)   December 31, 2016  Goodwill $ 51.8 $ – $ – $ 51.8 $ (354.2)  Assets held for sale 201.6 $ – – 201.6 (14.7)  Other real estate owned 22.5 – – 22.5 (3.2)  Impaired loans 151.9 – – 151.9 (26.8)  Total $ 427.8 $ – $ – $ 427.8 $ (398.9)  Assets of continuing operations that are measured at fair value on a non-recurring basis are as follows: Assets Held for Sale — – Assets held for sale are recorded at the lower of cost or fair value on the balance sheet. As there is no liquid secondary market for the assets held for sale in the Company’s portfolio, the fair value is estimated based on a binding contract, current letter of intent or other third-party valuation, or using internally generated valuations or discounted cash flow technique, all of which are Level 3 inputs. C arrying value of assets held for sale with impairment approximates fair value at March 31, 2017 and December 31, 2016. Other Real Estate Owned — Other real estate owned represents collateral acquired from the foreclosure of secured real estate loans. Other real estate owned is measured at LOCOM less disposition costs. Estimated fair values of other real estate owned are reviewed on a quarterly basis and any decline in value below cost is recorded as impairment. Estimated fair value is generally based upon broker price opinions or independent appraisals, adjusted for costs to sell. The estimated costs to sell are incremental direct costs to transact a sale, such as broker commissions , legal fees, closing costs and title transfer fees. The costs must be essential to the sale and would not have been incurred if the decision to sell had not been made. The range of inputs used to estimate cost to sell were 5.3% - 11.9%; which resulted in a weighted average of 6.1% at March 31, 2017. Also a significant unobservable input is the appraised value or the sales price and thus is classified as Level 3. As of the reporting date, OREO carry ing value approximates fair value. Impaired Loans — Impaired finance receivables of $500,000 or greater that are placed on non-accrual status are subject to periodic individual review in conjunction with the Company’s ongoing problem loan management (PLM) function. Impairment occurs when, based on current information and events, it is probable that CIT will be unable to collect all amounts due according to contractual terms of the agreement. Impairment is measured as the shortfall between estimated value and recorded investment in the finance receivable, with the estimated value determined using fair value of collateral and other cash flows if the finance r eceivable is collateralized, the present value of expected future cash flows discounted at the co ntract’s effective interest rate, or observable market prices. The significant unobservable inputs result in the Level 3 classification. As of the reporting date, the carry ing value of impaired loans approximates 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 are not required for disclosure.    Estimated Fair Value  Carrying  March 31, 2017 Value Level 1 Level 2 Level 3 Total  Financial Assets  Cash and interest bearing deposits $ 6,156.9 $ 6,156.9 $ – $ – $ 6,156.9  Derivative assets at fair value - non-qualifying hedges 67.5 – 67.4 0.1 67.5  Derivative assets at fair value - qualifying hedges 8.3 – 8.3 – 8.3  Assets held for sale (excluding leases) 396.1 – 118.2 291.1 409.3  Loans (excluding leases) 26,873.9 – 346.6 26,678.1 27,024.7  Investment securities (1) 4,476.3 0.2 3,421.3 1,058.3 4,479.8  Indemnification assets (2) 206.7 – – 169.2 169.2  Other assets subject to fair value disclosure and unsecured counterparty receivables ( 3) 516.9 – – 516.9 516.9  Financial Liabilities  Deposits (4) (32,360.9) – – (32,500.1) (32,500.1)  Derivative liabilities at fair value - non-qualifying hedges (52.2) – (39.9) (12.3) (52.2)  Derivative liabilities at fair value - qualifying hedges (0.8) – (0.8) – (0.8)  Borrowings (4) (14,841.5) – (14,231.1) (1,050.2) (15,281.3)  Credit balances of factoring clients (1,547.1) – – (1,547.1) (1,547.1)  Other liabilities subject to fair value disclosure (5) (736.9) – – (736.9) (736.9)   December 31, 2016  Financial Assets  Cash and interest bearing deposits $ 6,430.6 $ 6,430.6 $ – $ – $ 6,430.6  Derivative assets at fair value - non-qualifying hedges 94.7 – 94.7 – 94.7  Derivative assets at fair value - qualifying hedges 16.9 – 16.9 – 16.9  Assets held for sale (excluding leases) 428.4 – 175.0 264.6 439.6  Loans (excluding leases) 26,683.0 – 390.3 26,456.4 26,846.7  Investment securities (1) 4,491.1 200.4 3,199.6 1,094.2 4,494.2  Indemnification assets (2) 233.4 – – 201.0 201.0  Other assets subject to fair value disclosure and unsecured counterparty receivables ( 3) 712.2 – – 712.2 712.2  Financial Liabilities  Deposits (4) (32,323.2) – – (32,490.9) (32,490.9)  Derivative liabilities at fair value - non-qualifying hedges (68.8) – (57.3) (11.5) (68.8)  Borrowings (4) (15,097.8) – (14,457.8) (1,104.9) (15,562.7)  Credit balances of factoring clients (1,292.0) – – (1,292.0) (1,292.0)  Other liabilities subject to fair value disclosure (5) (1,003.6) – – (1,003.6) (1,003.6)  (1) Level 3 estimated fair value at March 31, 2017, includes debt securities AFS ( $470.5 million), securities carried at fair value with changes recorded in net income ( $268.9 million), non-marketable investments ( $249.5 million), and debt securities HTM ( $69.4 million). Level 3 estimated fair value at December 31, 2016 included debt securities AFS ( $485.5 million), debt securities carried at fair value with changes recorded in net income ( $283.5 million), non-marketable investments ( $256.4 million), and debt securities HTM ( $68.8 million).  (2) The indemnification assets included in the above table do not include Agency claims indemnification ( $106.4 million and $108.0 million at March 31, 2017 and December 31, 2016, respectively), as they are not considered financial instruments.  (3) Other assets subject to fair value disclosure primarily include accrued interest receivable and miscellaneous receivables. These assets have carrying values that approximate fair value generally due to the short-term nature and are classified as Level 3. The unsecured counterparty receivables primarily consist of amounts owed to CIT from GSI for debt discount, return of collateral posted to GSI and settlements resulting from market value changes to asset-backed securities underlying the TRS. (4) Deposits and borrowings include accrued interest, which is included in "Other liabilities" in the Balance Sheet. (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 approximate carrying value and are classified as level 3.  The methods and assumptions used to estimate the fair value of each class of financial instruments are explained below: Cash and interest bearing deposits —The carrying values of cash and cash equivalents are at face amount. The impact of the time value of money from the unobservable discount rate for restricted cash is inconsequential as of March 31, 2017 and December 31, 2016 . Accordingly cash and cash equivalents and restricted cash approximate estimated fair value and are classified as Level 1. Derivatives —The estimated fair values of derivatives were calculated using observable market data and represent the gross amount receivable or payable to terminate, taking into account current market rates, which represent Level 2 inputs, except for the TRS derivative and written options on certain CIT Bank CDs and credit derivatives that utilized Level 3 inputs. See Note 7 — Derivative Financial Instruments for notional principal amounts and fair values. Investment Securities —Debt and equity securities classified as AFS are carried at fair value, as determined either by Level 1 , Level 2 or Level 3 inputs. Debt securities classified as AFS included investments in U.S. federal government agency securities , U.S. Treasury Notes and supranational securities and were valued using Level 2 inputs, primarily quoted prices for similar securities. Debt securities carried at fair value with changes recorded in net income include non-agency MBS where the market for such securities is not active; therefore the estimated fair value was determined using a discounted cash flow technique, which is a Level 3 input. U.S. Treasury Bills and c ertain equity securities classified as AFS were valued using Level 1 inputs, primarily quoted prices in active markets . Debt securities classified as HTM include government agency securities and were valued using Level 2 inputs, primarily quoted prices for similar securities. For debt securities HTM where no market rate was available, Level 3 inputs were utilized. Debt securities HTM are securities that the Company has both the ability and the intent to hold until maturity and are carried at amortized cost and periodically assessed for OTTI, with the cost basis reduced when impairment is deemed to be other-than-temporary. Non-marketable equity investments utilize Level 3 inputs to estimate fair value and are generally recorded under the cost or equity method of accounting and are periodically assessed for OTTI, with the net asset values reduced when impairment is deemed to be other-than-temporary. For investments in limited partnership equity interests, the Company use d the net asset value provided by the fund manager as an appropriate measure of fair value. Assets held for sale —Assets held for sale are recorded at the lower of cost or fair value on the balance sheet . Of the assets held for sale above, $ 115.4 million carrying amount at March 31, 2017 was valued using Level 2 inputs. As there is no liquid secondary market for the other assets held for sale in the Company’s portfolio, the fair value is estimated based on a binding contract, current letter of intent or other third-party valuation, or using internally generated valuations or discounted cash flow technique, all of which are Level 3 inputs. Commercial loans are generally valued individually, while small ticket commercial loans are valued on an aggregate portfolio basis. Loans – Within the Loans category, there are several types of loans as follows: · Commercial and Consumer Loans - Of the loan balance above, $3 4 6.6 million and $390.3 million at March 31, 2017 and December 31, 2016, respectively, were valued using Level 2 inputs. As there is no liquid secondary market for the other loans in the Company’s portfolio, the fair value is estimated based on discounted cash flow analyses which use Level 3 inputs at both March 31, 2017 and December 31, 2016. In addition to the characteristics of the underlying contracts, key inputs to the analysis include interest rates, prepayment rates, and credit spreads. For the commercial loan portfolio, the market based credit spread inputs are derived from instruments with comparable credit risk characteristics obtained from independent third party vendors. As these Level 3 unobservable inputs are specific to individual loans / collateral types, management does not believe that sensitivity analysis of individual inputs is meaningful, but rather that sensitivity is more meaningfully assessed through the evaluation of aggregate carrying values of the loans. The fair value of loans at March 31, 2017 was $ 27.0 billion, which was 100.6% of carrying value. The fair value of loans at December 31, 2016 was $26 .8 billion, which was 100.6% of carrying value.  · Impaired Loans – The value of impaired loans is estimated using the fair value of collateral (on an orderly liquidation basis) if the loan is collateralized, the present value of expected cash flows utilizing the current market rate for such loan, or observable market price. As these Level 3 unobservable inputs are specific to individual loans / collateral types, management does not believe that sensitivity analysis of individual inputs is meaningful, but rather that sensitivity is more meaningfully assessed through the evaluation of aggregate carrying values of impaired loans relative to contractual amounts owed (unpaid principal balance or “UPB”) from customers. As of March 31, 2017, the UPB related to impaired loans totaled $252.8 million. Including related allowances, these loans are carried at $200 .6 million, or 79.4% of UPB. Of these amounts, $ 87.1 million and $ 74.6 million of UPB and carrying value, respectively, relate to loans with no specific allowance. As of December 31, 2016 the UPB related to impaired loans including loans for which the Company was applying the income recognition and disclosure guidance in ASC 310-30 (Loans and Debt Securities Acquired with Deteriorated Credit Quality), totaled $244.3 million. I ncluding related allowances, these loans were carried at $188.2 million, or 77.0% of UPB. Of these amounts, $74.7 million and $55.5 million of UPB and carrying value, respectively, relate to loans with no specific allowance. The difference between UPB and carrying value reflects cumulative charge-offs on accounts remaining in process of collection, FSA discounts and allowances. See Note 3 - Loans for more information. · PCI loans — These loans are 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 a lack of observable market data, the estimated fair value of these loan portfolios was based on an internal model

Regulatory Capital [Abstract]
Regulatory Capital	NOTE 10 — REGULATORY CAPITAL The Company and the Bank are each subject to various regulatory capital requirements administered by the FRB and the OCC. Quantitative measures established by regulation to ensure capital adequacy require that the Company and the Bank each maintain minimum amounts and ratios of Total, Tier 1 and Common Equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. In July 2013 the FRB, OCC and Federal Deposit Insurance Corporation issued a final rule (the “ Basel III Final Rule ”) establishing risk-based capital guidelines. We compute capital ratios in accordance with Federal Reserve capital guidelines and OCC capital guidelines for assessing adequacy of capital for the Company and CIT Bank, respectively. At March 31, 2017 and December 31, 2016, the regulatory capital guidelines applicable to the Company and the Bank were based on the Basel III Final Rule. The calculation of the Company’s regulatory capital ratios are subject to review and consultation with the FRB, which may result in refinements to amounts reported at March 31, 2017. The following table summarizes the actual and minimum required capital ratios:    CIT CIT Bank, N.A.

Income Taxes [Abstract]
Income Taxes	NOTE 11 – INCOME TAXES The Company’s global effective income tax rate from continuing operations for the first quarter and year-ago quarter was 42% including discrete tax items. The net discrete tax expense of $11.3 million for the current quarter included $13.9 million in deferred tax expense related to the restructuring of legal entities in preparation for the Commercial Air sale. T he year-ago quarter’s net discrete tax benefit of $11.0 million included a $13.9 million tax benefit, including interest and penalties, resulting from favorable resolution of a tax position on an international portfolio previously sold . The quarterly income tax expense is based on an updated projection of the Company’s annual effective tax rate. This updated 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 impact of any change in the projected annual effective tax rate from the prior quarter is reflected in the quarterly income tax expense. The change in the effective tax rate each period is impacted by a number of factors, including the relative mix of domestic and international earnings, adjustments to the valuation allowances, and discrete items. The near term future periods effective tax rate may vary from the actual year-end 2017 effective tax rate due to the changes in these factors. The Company maintained a valuation allowance of $39 million against certain non-U.S. reporting entities’ net DTAs and $240 million against U.S. state DTAs on certain NOLs as of March 31, 2017. The Company’s ability to recognize DTAs will be evaluated on a quarterly basis to determine if there are any significant events that would affect our ability to utilize existing DTAs. If events are identified that affect our ability to utilize our DTAs, valuation allowances may be adjusted accordingly. Liabilities for Uncertain Tax Positions The Company’s potential liability for uncertain tax positions before interest and penalties totaled $35.5 million at March 31, 2017 and $36.4 million at December 31, 2016. The Company anticipates changes to its uncertain tax positions from the resolution of open tax matters and closure of statutes of limitations . Management estimates that the total potential liability before interest and penalties may be reduced by up to $20 million within the next twelve months of which approximately $15 million will impact the income tax provision. On April 13, 2017, the Company received a fully executed Closing Agreement signed by the Executive Officer at the California Franchise Tax Board that will result in a favorable reduction of approximately $15 million in certain tax reserves on an uncertain tax position taken on prior year U.S. state tax returns. A favorable impact on the effective tax rate is expected in the second quarter. Approximately $5 million of the total $20 mil lion expected reduction reside i n entities that were included in the Commercial Air sale. The Company’s accrued liability for interest and penalties totaled $13.5 million at March 31, 2017 and $11.7 million at December 31, 2016. The Company recognizes accrued interest and penalties on unrecognized tax benefits in income tax expense.

Commitments [Abstract]
Commitments	NOTE 12 — COMMITMENTS The accompanying table summarizes credit-related commitments , as well as purchase and funding commitments: Commitments (dollars in millions)       March 31, 2017 December 31,  Due to Expire 2016  Within After Total Total  One Year One Year Outstanding Outstanding  Financing Commitments  Financing assets $ 1,550.9 $ 4,670.1 $ 6,221.0 $ 6,008.1  Letters of credit  Standby letters of credit 45.2 210.8 256.0 232.2  Other letters of credit 16.3 - 16.3 14.0  Guarantees  Deferred purchase agreements 1,875.6 - 1,875.6 2,060.5  Guarantees, acceptances and other recourse obligations 1.1 - 1.1 1.6  Purchase and Funding Commitments  Aerospace purchase commitments 951.0 7,580.3 8,531.3 8,683.5  Rail and other purchase commitments 270.7 43.0 313.7 300.7    Discontinued Operations The Aerospace purchase commitments in the table above are associated with Aerospace discontinued operations. Financing commitments include HECM reverse mortgage loan commitments associated with Financial Freedom discontinued operations of $ 40 million at March 31, 2017 and $42 million at December 31, 2016.  Financing Commitments Commercial Financing commitments, referred to as loan commitments or lines of credit, reflect CIT’s agreements to lend to its customers, subject to the customers’ compliance with contractual obligations. 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 $ 964 million at March 31, 2017 and $572 million at December 31, 2016. Financing commitments also include credit line agreements to Business Capital clients that are cancellable by us only after a notice period. The notice period is typically 90 days or less. The amount available under these credit lines, net of the amount of receivables assigned to us, was $405 million at March 31, 2017 and $335 million at December 31, 2016. As financing commitments may not be fully drawn, may expire unused, may be reduced or cancelled at the customer’s request, and may require the customer to be in compliance with certain conditions, total commitment amounts do not necessarily reflect actual future cash flow requirements. The table above includes approximately $1.5 billion of undrawn financing commitments at March 31, 2017 and $1.7 billion at December 31, 2016 for instances where the customer is not in compliance with contractual obligations or does not have adequate collateral to borrow against the unused facility , and therefore CIT does not have the contractual obligation to lend. At March 31, 2017, 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 In conjunction with the OneWest Transaction, the Company is committed to fund draws on certain reverse mortgages in conjunction with loss sharing agreements with the FDIC. The FDIC agreed to indemnify the Company for losses on the first $200 million of draws that occur subsequent to the purchase date. In addition, the FDIC agreed to fund any other draws in excess of the $200 million. The Company’s net exposure for loan commitments on the reverse mortgage draws on those purchased loan s was $57 million at March 31, 2017 and $55 million at December 31, 2016. See Note 5 – Indemnification Assets of the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 for further discussion on loss sharing agreements with the FDIC. In addition, as servicer of HECM loans, the Company is required to repurchase the loan out of the GNMA HMBS securitization pools once the outstanding principal balance is equal to or greater than 98% of the maximum claim amount. Also included was the Company’s commitment 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 made on the purchased HELOCs. 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 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 ninety 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 $1,772 million and $1,962 million of DPA credit protection at March 31, 2017 and December 31, 2016, respectively, related to receivables which have been presented to us for credit protection after shipment of goods has occurred and the customer has been invoiced. The table also includes $104 million and $99 million available under DPA credit line agreements, net of the amount of DPA credit protection provided at March 31, 2017 and December 31, 2016, respectively. The DPA credit line agreements specify a contractually committed amount of DPA credit protection and are cancellable by us only after a notice period. The notice period is typically 90 days or less. 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 receivables, 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 $ 11.6 million and $6.1 million at March 31, 2017 and December 31, 2016, respectively. Purchase and Funding Commitments CIT’s purchase commitments relate primarily to purchases of commercial aircraft and rail equipment. Commitments to purchase new commercial aircraft are predominantly with Airbus Industries (“Airbus”) and The Boeing Company (“Boeing”). CIT may also commit to purchase an aircraft directly from an airline. Pursuant to existing contractual commitments, 126 aircraft remain to be purchased from Airbus, Boeing and Embraer at March 31, 2017. After the Com mercial Air sale, which occurred on April 4, 2017, CIT will no longer have such commitments. The Company’s rail business entered into commitments to purchase railcars from multiple manufacturers. At March 31, 2017, approximately 2,520 railcars remain to be purchased from manufacturers with deliveries through 2018. Rail equipment purchase commitments are at fixed prices subject to price increases for certain materials. Other purchase commitments primarily relate to Equipment Finance. Other Commitments The Company has commitments to invest in affordable housing investments, and other investments qualifying for community reinvestment tax credits. These commitments were $54 million at March 31, 2017 and $62 million at December 31, 2016. These commitments are payable on demand and are recorded in Other liabilities. In addition, as servicer of HECM loans, the Company is required to purchase loans out of the GNMA HMBS securitization pools once the outstanding principal balance is equal to or greater than 98% of the maximum claim amount. Refer to Note 3 – Loans for further detail regarding the purchased HECM loans due to this servicer obligation.

Contingencies [Abstract]
Contingencies	NOTE 1 3 — CONTINGENCIES Litigation 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 relating to matters that arise in connection with the conduct of its business (collectively, “Litigation”). 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 results of Litigation that is currently pending, taken together, 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 where losses are reasonably possible, management currently estimates the aggregate range of reasonably possible losses as up to $60 million in excess of established reserves and insurance related to those matters, if any. 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 March 31, 2017. The 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. B razilian 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 Imposto sobre Circulaco de Mercadorias e Servicos (“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 have been filed in a general amnesty program. In conjunction with the stock sale, the Company posted a letter of credit in the amount o f approximately 71 million Reais (approximately $23 million USD) to secure the indemnity obligation for the ICMS Tax Appeals.  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. Subject to certain requirements, the loans acquired from the FDIC are covered by indemnification agreements. 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 request 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. The Company continues to cooperate with the investigation and is engaged in discussions with the HUD-OIG regarding resolution of the matter. We do not expect the outcome of the investigation to have a material adverse effect on the Company’s financial condition or results of operations in light of existing reserves.  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 requests documents and other information related to Financial Freedom’s HECM loan busines s in the State of New York. The Company is in the process of evaluating and preparing to respond to the subpoena and does not have sufficient information to make an assessment of the outcome or the impact of the NYAG subpoena. HUD In the first quarter of 2017, the HUD accepted a complaint from the California Reinvestment Coalition (“CRC”) alleging that CIT engaged in discriminatory housing lending practices from 2011 until the present, in violation of the Fair Housing Act (“FHA”). The Company has filed a response to the complaint denying the allegations. HUD has not yet determined whether there is “reasonable cause” to pursue or dismiss the complaint. Forward Mortgage Obligations As owner and servicer of forward residential mortgage loans, the Company is exposed to contingent obligations for breaches of servicer and other contractual obligations as set forth in industry regulations, in servicing agreements and other agreements with the applicable counterparties, such as the FDIC, Fannie Mae and other third party investors. The Company has established reserves for contingent liabilities associated with continuing forward mortgage operations. While the Company believes that such accrued liabilities are adequate, management currently estimates the aggregate range of reasonably possible losses as up to $5 million in excess of established reserves and insurance, if any, as of March 31, 2017. This estimate is based on information currently available as of March 31, 2017. The obligations underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate.  Indemnification Obligations  In connection with the OneWest acquisition, CIT assumed the obligation to indemnify Ocwen Loan Servicing, LLC (“Ocwen”) against certain claims that may arise from servicing errors, which are deemed attributable to the period prior to June 2013, when OneWest sold its servicing business to Ocwen, such as repurchase demands, non-recoverable servicing advances and compensatory fees imposed by the GSEs for servicer delays in completing the foreclosure process within the prescribed timeframe established by the servicer guides or agreements, exclusive of losses or repurchase obligations and certain agency fees, and which are limited to an aggregate amount of $150 million for claims noticed by February 28, 2017 to CIT. Ocwen is responsible for liabilities arising from servicer obligations following the service transfer date because substantially all risks and rewards of ownership have been transferred; except for certain Agency fees or loan repurchase amounts. As of March 31, 2017, the cumulative indemnification obligation totaled approximately $56 million, which reduced the Company’s $150 million maximum potential indemnity obligation already paid to Ocwen. Because of the uncertainty in the ultimate resolution and estimated amount of the indemnification obligation, it is reasonably possible that the obligation could exceed the Company’s recorded liability by up to approximately $25 million as of March 31, 2017.  In addition, CIT assumed OneWest Bank’s obligations to indemnify Specialized Loan Servicing, LLC (“SLS”) against certain claims that may arise that are attributable to the period prior to September 2013, the servicing transfer date, when OneWest sold a portion of its servicing business to SLS, such as repurchase demands and non-recoverable servicing advances. SLS is responsible for substantially all liabilities arising from servicer obligations following the service transfer date.  Mortgage Servicing Consent Orders  As a result of CIT Group Inc.’s acquisition of OneWest Bank, CIT (as successor to IMB Holdco LLC) is subject to a Consent Order with the FRB related to residential mortgage servicing operations. The original consent order was entered into with IMB Holdco LLC and the Office of Thrift Supervision in April 2011. Following IMB Holdco’s conversion to a bank holding company the Consent Order was amended in March 2014 to name the FRB as the appropriate regulator to administer the Order. A similar Consent Order had been entered into with the OCC, but in July 2015, immediately prior to completion of CIT’s acquisition of OneWest Bank the OCC terminated its Consent Order. However, the FRB continued its Consent Order in place and oversight was transferred to the Federal Reserve Board New York and CIT succeeded to the Consent Order obligations. The FRB’s Consent Order remains outstanding although improvements required by the Consent Order have been implemented including the completion of an Independent Foreclosure Review in 2014, resulting in approximately $12.7 million of remediation payments being made payable to borrowers.

Certain Relationships And Related Transactions [Abstract]
Certain Relationships And Related Transactions	NOTE 14 — CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS  During the third quarter of 2015, Strategic Credit Partners Holdings LLC (the “JV”), a joint venture between CIT Group Inc. (“CIT”) and TPG Special Situations Partners (“TSSP”), was formed. The JV extends credit in senior-secured, middle-market corporate term loans, and, in certain circumstances, is a participant to such loans. Participation could be in corporate loans originated by CIT. The JV may acquire other types of loans, such as subordinate corporate loans, second lien loans, revolving loans, asset backed loans and real estate loans. Through March 31, 2017, loans of $220.0 milli on were sold to the joint venture. CIT also maintains an equity interest of 10% in the JV, and our investment was $7.1 million and $5.4 million at March 31, 2017 and December 31, 2016, respectively.  The Company was party to two joint ventures (collectively “TC-CIT Aviation”) between CIT Aerospace and Century Tokyo Leasing Corporation (“CTL”). CIT sold TC-CIT Aviation on March 31, 2017 making its minority equity investment $0 and $81 million at March 31, 2017 and December 31, 2016, respectively. During the quarter ended March 31, 2017, CIT recorded servicing fees of $3.4 million and recognized a gain of $13.7 million on the sale of TC-CI T Aviation in discontinued ope rations. CIT invests in various trusts, partnerships, and limited liability corporations established in conjunction with structured financing transactions of equipment, power and infrastructure projects. CIT’s interests in these entities were entered into in the ordinary course of business. Other assets included approximately $213 million and $220 million at March 31, 2017 and December 31, 2016, respectively, of investments in non-consolidated entities relating to such transactions that are accounted for under the equity or cost methods. The combination of investments in and loans to non-consolidated entities represents the Company’s maximum exposure to loss, as the Company does not provide guarantees or other forms of indemnification to non-consolidated entities. As of March 31, 2017 and December 31, 2016, a wholly-owned subsidiary of the Company subserviced loans for a related party with unpaid principal balances of $7.6 million, respectively.

Subsequent Events	NOTE 1 6 – SUBSEQUENT EVENTS  Sale of CIT Commercial Air On October 6, 2016, CIT announced a definitive agreement to sell Commercial Air to Avolon. On April 4, 2017, CIT completed the Commercial Air Sale. The aggregate purchase price paid by the purchaser and its subsidiaries to CIT and its subsidiaries for the Commercial Air Sale was approximately $10.4 billion in cash, which is equal to (a) the adjusted net asset amount of the Commercial Air business as of the closing of the Commercial Air Sale plus (b) a premium of approximately $627 million . Redemption of Senior Unsecured Debt  On April 4, 2017, CIT announced that it has given notice of its intention to redeem and on May 4, 2017, CIT redeemed 100% of the aggregate principal amount (approximately $4.84 billion) of its outstanding (i) $1,725.8 million, 4.250% Senior Unsecured Notes due August 2017; (ii) $1,465.0 million, 5.250% Senior Unsecured Notes due March 2018; (iii) $695.0 million, 6.625% Series C Unsecured Notes due April 2018; and (iv) $955.9 million, 5.000% Senior Unsecured Notes due May 2018, at an aggregate premium of $98 million. Senior Unsecured Debt Tender Offer On April 4, 2017, CIT commenced an offer to purchase for cash (the “Debt Tender Offer”) up to $950 million in the aggregate of its (i) 5.500% Series C Unsecured Notes due February 2019; (ii) 5.375% Senior Unsecured Notes due May 2020; and (iii) 5.000% Senior Unsecured Notes due August 2022 (the “2022 Notes” and, together with the 2019 Notes and the 2020 Notes, the “Notes”). On April 18, 2017, CIT announced that the Debt Tender Offer was oversubscribed, that the Company elected to increase the aggregate maximum principal amount of Notes accepted for purchase in the Tender Offer to $969 million, and that it had elected to early settle the Debt Tender Offer. A total principal amount of $969 million of our 5.500% Series C Unsecured Notes due 2019 have been repurchased for total consideration of $1.04 billion, including accrued interest of $9 million. Equity Tender Offer On April 27, 2017, CIT commenced a cash tender offer by means of a “modified” Dutch auction (the “Equity Tender Offer”) for up to $2 .75 billion of shares of its common stock, par value $0.01 per share, at a purchase price not greater than $48.00 per share and not less than $43.00 per share, and further pursuant to the terms and conditions set forth in the related Offer to Purchase, dated April 27, 2017, and the accompanying letter of transmittal .

Business And Summary Of Significant 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 our Form 10-K for the year ended December 31, 2016. The accounting and financial reporting policies of CIT Group Inc. 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. Som e o f th e mo re signifi can t estimate s include : allowanc e fo r loa n losses , loan impairment , fai r valu e determination , leas e r esidua l values , liabili tie s fo r uncertai n ta x positions , r ealizabilit y o f defer r e d ta x assets, pu r chas e accountin g adjustments , indemnificatio n assets , good will , intangibl e assets , an d contingen t liabilities, including amounts associated with the discontinued operation .

Principles Of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include financial information related to CIT Group Inc. and its majority-owned subsidiaries and those variable interest entities (“VIEs”) where the Company is the primary beneficiary. In preparing the consolidated financial statements, all significant inter-company 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 March 31, 2017 and December 31, 2016 included certain assets and liabilities of the Commercial Air business, the Business Air business, along with the Financial Freedom business that was acquired as part of the OneWest Transaction. Income from discontinued operations reflects the activities of the Aerospace (Commercial Air and Business Air) and Financial Freedom businesses for the quarters ended March 31, 2017 and 2016.  See further discussions in Note 2 - Discontinued Operations.
Revisions Of Previously Issued Statements Of Cash Flows	Revisions of Previously Issued Statements of Cash Flows  The Company has revised the Statement of Cash Flows for the three months ended March 31, 2016 in connection with immaterial errors impacting the classification of certain balances between line items and categories as previously disclosed in its Form 10-K, Note 29 – Selected Quarterly Financial Data , for the year ended December 31, 2016. The misclassifications resulted in an overstatement of net cash flows provided by operations of $166.4 million, an overstatement of net cash flows used in investing activities of $203.9 million, and an understatement of net cash flows used in financing activities of $35.2 million. The Company evaluated the impact of the errors and has concluded that individually and in the aggregate, the errors were not material to any previously issued financial statements.  Cash Flow balances disclosed in the December 31, 2016 Form 10-K have been updated to reflect the adoption of ASU 2016 ‐ 09: Compensation—Stock Compensation (Topic 718) , as discussed later in this Note.
Accounting Pronouncements Adopted	Financial Accounting Standards Board (“FASB”) Standards Adopted since January 1, 2017  Accounting Standards Update (“ASU”) 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument does not, in and of itself, require de-designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The standard was adopted as of January 1, 2017. Historically, CIT has not novated any derivative instrument that was designated as a hedging instrument and as such the adoption of this ASU has no impact on CIT’s Consolidated Financial Statements.  ASU 2016-06, Derivatives and Hedging (Top 815): Contingent Put and Call Options in Debt Instruments clarifies that in assessing whether an embedded contingent put or call option is clearly and closely related to the debt host, an entity is required to perform only the four-step decision sequence in ASC 815, as amended by the ASU. Accordingly, when a call (put) option is contingently exercisable, there is no requirement that an entity must assess whether the event that triggers the ability to exercise a call (put) option is related to interest rate or credit risk. CIT adopted this amendment as of January 1, 2017. The adoption did not result in a significant impact on the Company’s financial statements or disclosures.  ASU 2016-07, Investments—Equity method and joint ventures (Topic 323), Simplifying the Transition to the Equity Method of Accounting ; eliminates the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. For available ‐ for ‐ sale securities that become eligible for the equity method of accounting, any unrealized gain or loss recorded within accumulated other comprehensive income should be recognized in earnings at the date the investment initially qualifies for the use of the equity method. The new standard should be applied prospectively for investments that qualify for the equity method of accounting after the effective date. CIT adopted this amendment as of January 1, 2017. The adoption did not result in a significant impact on the Company’s financial statements or disclosures.  ASU 2016 ‐ 09: Compensation—Stock Compensation (Topic 718), simplifies several aspects of the accounting for share based payment award transactions to employees. The standard requires that all excess tax benefits and tax deficiencies that pertain to employee stock-based incentive payments be recognized within income tax expense in the consolidated statements of income, rather than within additional paid-in capital. When an employee’s shares are used to satisfy the employers’ statutory income tax withholding obligation, the threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdiction. The standard also allows an entity to make a Company-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. CIT adopted this Update as of January 1, 2017. The adoption did not result in a significant impact to CIT’s financial statement disclosures. CIT has changed its accounting policy to account for forfeitures as they occur in order to determine the amount of compensation cost to be recognized in each period. The Company also retrospectively applied the presentation requirements for cash flows related to employee taxes paid for withheld shares, resulting in a reclassification of $10.5 million from operating activities to financing activities for March 31, 2016 in the Company’s consolidated Statements of Cash Flows. ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323) amends certain SEC paragraphs to incorporate SEC staff announcements made at the September 22, 2016, and November 17, 2016, Emerging Issues Task Force meetings. ASU 2017-03 incorporates these SEC staff views into ASC 250 and adds references to that guidance in the transition paragraphs of each of the three new standards ASU 2014-09, Revenue from Contracts with Customers (Topic 606), ASU 2016-02, Leases (Topic 842), and ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument s relating to expanded disclosures under SAB 74, Topic 11.M. The ASU also conforms ASC 323-740-S99-2, which describes the SEC staff’s views on accounting for investments in qualified affordable housing projects, to the guidance issued in ASU 2014-01.  CIT adopted the guidance as it relates to Topic 250, Accounting Changes and Error Corrections, and ASC Topic 323, Investments—Equity Method and Joint Ventures as of January 1, 2017. The adoption did not result in a significant impact on the Company’s financial statements or disclosures. To the extent such corrections impact the three new standards, CIT plans to align the adoption of the update with the relevant adoption dates of these standards.  ASU 2017-04 , Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of the goodwill impairment test under current GAAP) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on today’s Step 1). The one-step impairment test will be applied to goodwill for all reporting units, even those with zero or negative carrying amounts. This guidance is required to be applied prospectively to transactions occurring within the period of adoption. CIT early adopted this standard as of January 1, 2017.

Recent Accounting Pronouncements	Recent Accounting Pronouncements The following accounting pronouncements were issued by the FASB prior to January 1, 2017, but are not yet effective. Refer to Note 1, Business and Summary of Significant Accounting Policies on Form 10-K for the year ended December 31, 2016 for a detailed description of the pronouncements.  · ASU 2014-09 , Revenue from Contracts with Customers (Topic 606) · ASU 2015-14 , Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date; · ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities; · ASU 2016-02, Leases (Topic 842); · ASU 2016-08, Revenue from Contracts with Customers(Topic 606): Principal versus Agent Considerations · ASU 2016-10 , Revenue from Contracts with Customers(Topic 606): Identifying Performance Obligations and Licensing ; · ASC 2016-11 , Rescission of Certain SEC Staff Observer Comments upon Adoption of Topic 606, Revenue from Contracts with Customers; · ASU 2016-12 , Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and Practical Expedients; · ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments; · ASU 2016-15 , Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments; · ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory; · ASU 2016-18 , Statement of Cash Flows (Topic 230): Restricted Cash ( a consensus of the FASB Emerging Issues Task Force); · ASU 2016-20 , Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. Revenue Recognition The revenue recognition guidance (ASU 2014-09, ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-11, ASU 2016-12, ASU 2016-20) establishes the principles to apply to determine the amount and timing of revenue recognition, specifying the accounting for certain costs related to revenue, and requiring additional disclosures about the nature, amount, timing and uncertainty of revenues and related cash flows. The core principle is that a company will recognize revenue when it transfers control of goods or services to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The standard also changes the accounting for certain contract costs, including whether they may be offset against revenue in the Consolidated Statements of Income, and requires additional disclosures about revenue and contract costs. Companies can choose to apply the standard using either the full retrospective approach or a modified retrospective approach. Under the modified approach, financial statements will be prepared for the year of adoption using the new standard, but prior periods will not be adjusted. Instead, companies will recognize a cumulative catch-up adjustment to the opening balance of retained earnings at the effective date for contracts that still require performance by the company and disclose all line items in the year of adoption as if they were prepared under today’s revenue guidance. The required effective date is January 1, 2018.  The review and analysis of CIT’s individual revenue streams is currently underway. “Interest Income” and “Rental Income on Operating Leases”, CIT’s two largest revenue items, are scoped out of the new guidance; as are many other revenues relating to financial assets and liabilities, including loans, leases, securities and derivatives. As such, the majority of our revenues will not be impacted; however, certain ancillary revenues and components of “Other income” are being assessed at a contractual level pursuant to the new standard. We expect our accounting policies will not change materially.  CIT plans to adopt the standard in the first quarter of 2018 and expects to use the modified retrospective method (cumulative initial effect recognized at the date of adoption, with additional footnote disclosures). However, we are continuing to evaluate the impact of the standard, and our adoption method is subject to change. CIT does not anticipate a significant impact on our financial statements and disclosures upon adoption of the standard. Our evaluations are not final and we continue to assess the impact of the Update on our revenue contracts.  Leases ASU 2016-02, Leases was issued in February 2016, is intended to increase transparency and comparability of accounting for lease transactions, and will require all leases to be recognized on the balance sheet as lease assets and lease liabilities.  Lessor accounting remains similar to the current model, but updated to align with certain changes to the lessee model ( e.g., certain definitions, such as initial direct costs, have been updated) and the new revenue recognition standard. Lease classifications by lessors are similar, operating, direct financing, or sales-type.  Lessees will need to recognize all leases longer than twelve months on the Consolidated balance sheets as lease liabilities with corresponding right-of-use assets. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit thresholds. The ASU will require both quantitative and qualitative disclosures regarding key information about leasing arrangements.   The standard is effective for the Company on January 1, 2019. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented.  Although the new guidance does not significantly change lessor accounting, CIT will need to determine the impact to both, where it is a lessee and a lessor: · Lessor accounting: Given limited changes to Lessor accounting, we do not expect material changes to recognition or measurement. Current lease administration and/or reporting systems and processes will need to be evaluated and updated as required to ensure appropriate lease ‐ type identification and classification. · Lessee accounting: The new standard will result in virtually all leases being reflected on the balance sheet. The impact on lessee accounting also includes identification of any embedded leases included in service contracts that CIT has with vendors.  The Company is currently evaluating the effect of this ASU on its financial statements and disclosures. CIT management has assembled a project committee to assess the impact in order to implement and adopt the standard in the first quarter of 2019.  Credit Losses ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, introduces a forward-looking “expected loss” model (the “Current Expected Credit Losses” (“CECL”) model) to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale (“AFS”) debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The ASU replaces the existing incurred loss impairment guidance and establishes a single allowance framework for financial assets carried at amortized cost (including held to maturity (“HTM”) securities), which will reflect management’s estimate of credit losses over the full remaining expected life of the financial assets. It eliminates existing guidance for purchase credit impaired (“PCI”) loans, and requires recognition of an allowance for expected credit losses on financial assets purchased with more than insignificant credit deterioration since origination. In addition, it amends existing impairment guidance for AFS securities to incorporate an allowance, which will allow for reversals of impairment losses in the event that the credit of an issuer improves. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted (modified-retrospective approach). A prospective transition approach is required for debt securities for which an other than temporary impaired (“OTTI”) had been recognized before the effective date. A prospective transition approach should be used for purchased with more than insignificant credit deterioration (“PCD”) assets where upon adoption; the amortized cost basis should be adjusted to reflect the addition of the allowance for credit losses.  The ASU will be effective January 1, 2020. Early adoption of the guidance will be permitted for all entities for fiscal years beginning January 1, 2019. CIT is currently evaluating the effect of this ASU on its financial statements and disclosures.  The following accounting pronouncements have been issued by the FASB during the first quarter of 2017 but are not yet effective:  · ASU 2017-01 , Business Combinations (Topic 805): Clarifying the Definition of a Business; · ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets; · ASU 2017-07, Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost; · ASU 2017-08 , Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.  In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This guidance narrows the definition of a business. This standard provides guidance to assist entities with evaluating when a set of transferred assets and activities is a business. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted. This guidance must be applied prospectively to transactions occurring within the period of adoption. CIT expects to adopt this guidance effective January 1, 2018. The Company is currently evaluating the impact of this ASU.  In February 2017, FASB issued ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets. This guidance clarifies the scope of accounting for derecognition or partial sale of nonfinancial assets to exclude all businesses and non-profit activities. ASU 2017-05 also provides a definition for in substance non-financial assets and additional guidance on partial sales of non-financial assets. The amendments are effective at the same time Topic 606, Revenue from Contracts with Customers , is effective. For public entities, they are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of this ASU on its financial statements and disclosures and plans to adopt in conjunction with the revenue recognition standard described earlier in the first quarter of 2018.  In March 2017, FASB issued the ASU 2017-07 - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost to improve the reporting of net periodic benefit cost from defined benefit pension plans and other postretirement benefit plans in the financial statements of all employers. The ASU amends ASC 715, Compensation — Retirement Benefits, to require employers that present a measure of operating income in their statement of income to include only the service cost component of net periodic pension cost and net periodic postretirement benefit cost in operating expenses (together with other employee compensation costs). The other components of net benefit cost, including amortization of prior service cost/credit, and settlement and curtailment effects, are to be included in non- operating expenses. Employers that do not present a measure of operating income are required to include the service cost component in the same line item as other employee compensation costs. Employers are required to include all other components of net benefit cost in a separate line item(s). The line item(s) in which the components of net benefit cost other than the service cost are included needs to be identified as such on the income statement or in the disclosures. The ASU also stipulates that only the service cost component of net benefit cost is eligible for capitalization.  This is applicable for public entities after December 15, 2017, including interim periods within those periods. Early adoption is permitted as of the beginning of an annual period for which financial statements have not yet been issued or made available for issuance. The amendments related to presentation of service cost and other components in the income statements must be applied retrospectively to all periods presented. The amendments related to the capitalization of the service cost component should be applied prospectively, on and after the date of adoption. The Company is currently evaluating the impact of this ASU on its financial statements and disclosures and does not intend to early adopt this standard. The purpose of ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities is to amend the amortization period for purchased callable debt securities held at a premium by shortening the amortization period to the earliest call date. Current guidance does not allow for the recognition of an early repayment of principal even if there is a high degree of certainty that the call will be exercised. As a result a loss in earnings must be recognized when the call is exercised at a premium. This accounting change does not impact securities held at a discount. For public business entities the effective date for this ASU is for fiscal years, and the interim periods with in those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact of this ASU on its financial statements and disclosures and does not intend to early adopt this standard.

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 ("LCH") continue to be accounted for as "collateralized-to-market" and variation margin balances are characterized as collater al against derivative exposures At March 31, 2017, gross amount of recognized assets and liabilities were lower by $5.1 million and $16.7 million, respectively. (2) 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 (“Derivative Financial Instruments”) 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 . (3) Collateral pledged or received is included in Other assets or Other liabilities, respectively.
