Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature Of Operations And Basis Of Presentation	NOTE 1 – Nature of Operations and Basis of Presentation Nature of Operations Stifel Financial Corp. (the “Company”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. We have offices throughout the United States and Europe. Our major geographic area of concentration is throughout the United States, with a growing presence in Europe. Our company’s principal customers are individual investors, corporations, municipalities, and institutions. On January 4, 2016, the Company completed the acquisition of Eaton Partners, LLC (“Eaton Partners”), a global fund placement and advisory firm. Eaton Partners will retain its brand name and will be run as a Stifel company. The acquisition was funded with cash from operations and our common stock. On May 5, 2016, the Company completed the acquisition of ISM Capital LLP (“ISM”), an independent investment bank focused on international debt capital markets. The acquisition of ISM adds to the Company’s debt capital markets origination, sales and research capabilities in Europe, including an end-to-end platform for convertible securities and other equity-linked debt instruments. The acquisition was funded with cash from operations. Basis of Presentation The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Keefe, Bruyette & Woods, Inc., and Stifel Bank & Trust (“Stifel Bank”). All material intercompany balances and transactions have been eliminated. Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries. We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Pursuant to these rules and regulations, we have omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles. In management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise noted) necessary to fairly present our financial position, results of operations and cash flows. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and the notes thereto in our Annual Report on Form 10-K for the year ended December 31, 2015 on file with the SEC. Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material. There have been no material changes in our significant accounting policies, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2015.

Recently Issued Accounting Guid

Recently Issued Accounting Guidance	6 Months Ended
	Jun. 30, 2016
Prospective Adoption Of New Accounting Pronouncements [Abstract]
Recently Issued Accounting Guidance	NOTE 2 – Recently Issued Accounting Guidance Financial Instruments – Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The guidance requires that credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. The guidance is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for our Company), including interim periods within that reporting period. Early adoption is permitted for annual periods beginning after December 15, 2018. We are currently evaluating the effect that the new guidance will have on our consolidated financial statements. Share-Based Payments In March 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”) that requires an entity to record all excess tax benefits and tax deficiencies as an income tax benefit or expense in the income statement. ASU 2016-09 will also require an entity to elect an accounting policy to either estimate the number of forfeitures or account for forfeitures when they occur. The guidance is effective for fiscal years beginning after December 15, 2016 (January 1, 2017 for our company). We are currently evaluating the effect that the new guidance will have on our consolidated financial statements. Leases In February 2016, the FASB issued ASU No. 2016-02, “Leases” that requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. The new standard must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. The guidance is effective for fiscal years beginning after December 15, 2018 (January 1, 2019 for our company). Early adoption is permitted. We are currently evaluating the transition method that will be elected and the effect that the new guidance will have on our consolidated financial statements. Financial Assets and Financial Liabilities In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” that will change the income statement impact of equity investments held by an entity, and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The guidance is effective for fiscal years beginning after December 15, 2017 (January 1, 2018 for our company). We are currently evaluating the effect that the new guidance will have on our consolidated financial statements. Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share In May 2015, the FASB issued ASU No. 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)” (“ASU 2015-07”). The guidance removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The guidance also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The guidance is effective for fiscal years beginning after December 15, 2015 (January 1, 2016 for our company). See Note 4 – Fair Value Measurements. Interest - Imputation of Interest In April 2015, the FASB issued ASU No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-03”). The guidance in ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The guidance is effective for fiscal years beginning after December 15, 2015 (January 1, 2016 for our company) and is required to be applied retrospectively to all periods presented beginning in the year of adoption. Upon the adoption of ASU 2015-03 by our company on January 1, 2016, the impact was a reduction in both other assets and senior notes of $9.6 million. In accordance with ASU No. 2015-03, previously reported amounts have been conformed to the current presentation, as reflected in the consolidated statements of financial condition. The impact as of December 31, 2015 was a reduction to both total assets and total liabilities of $9.9 million. Revenue Recognition In April 2016, the FASB issued ASU No. 2016-10, “Identifying Performance Obligations and Licensing” that amends the revenue guidance in ASU 2014-09 on identifying performance obligations. The effective date of the new guidance will coincide with ASU 2014-09 during the first quarter 2018. We are currently evaluating the effect that the new guidance will have on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” (“ASU 2016-08”) that amends the principal versus agent guidance in ASU 2014-09. ASU 2016-08 clarifies that the analysis must focus on whether the entity has control of the goods or services before they are transferred to the customer. ASU 2016-08 also provides additional guidance about how to apply the control principle when services are provided and when goods or services are combined with other goods or services. The effective date of the standard for the Company will coincide with ASU 2014-09 during the first quarter 2018. We are currently evaluating the effect that the new guidance will have on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," ("ASU 2014-09") that supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09 requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also requires additional disclosures regarding the nature, amount, timing and uncertainty of revenue that is recognized. The FASB has approved a one year deferral of this standard, and this pronouncement is now effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and is to be applied using one of two retrospective application methods, with early application not permitted. We are currently evaluating the impact the new guidance will have on our consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 4 – Fair Value Measurements We measure certain financial assets and liabilities at fair value on a recurring basis, including financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. We generally utilize third-party pricing services to value Level 1 and Level 2 available-for-sale investment securities, as well as certain derivatives designated as cash flow hedges. We review the methodologies and assumptions used by the third-party pricing services and evaluate the values provided, principally by comparison with other available market quotes for similar instruments and/or analysis based on internal models using available third-party market data. We may occasionally adjust certain values provided by the third-party pricing service when we believe, as the result of our review, that the adjusted price most appropriately reflects the fair value of the particular security. Following are descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value. The descriptions include an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. Financial Instruments Owned and Available-For-Sale Securities When available, the fair value of financial instruments is based on quoted prices in active markets and reported in Level 1. Level 1 financial instruments include highly liquid instruments with quoted prices, such as equity securities listed in active markets, corporate fixed income securities, and U.S. government securities. If quoted prices are not available for identical instruments, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include U.S. government agency securities, mortgage-backed securities, corporate fixed income securities infrequently traded, state and municipal securities, asset-backed securities, and equity securities not actively traded. We have identified Level 3 financial instruments to include certain equity securities with unobservable pricing inputs and certain mortgage-backed securities. Level 3 financial instruments have little to no pricing observability as of the report date. These financial instruments do not have active two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. Investments Investments carried at fair value primarily include corporate equity securities, auction-rate securities (“ARS”), and private company investments. Corporate equity securities and U.S. government securities are valued based on quoted prices in active markets and reported in Level 1. ARS for which the market has been dislocated and largely ceased to function are reported as Level 3 assets. ARS are valued based upon our expectations of issuer redemptions and using internal discounted cash flow models that utilize unobservable inputs. Direct investments in private companies may be valued using the market approach and were valued based on an assessment of each underlying investment, incorporating evaluation of additional significant third-party financing, changes in valuations of comparable peer companies, the business environment of the companies, market indices, assumptions relating to appropriate risk adjustments for nonperformance, and legal restrictions on disposition, among other factors. The fair value derived from the methods used are evaluated and weighted, as appropriate, considering the reasonableness of the range of values indicated. Under the market approach, fair value may be determined by reference to multiples of market-comparable companies or transactions, including earnings before interest, taxes, depreciation, and amortization (“EBITDA”) multiples. For securities utilizing the market comparable companies valuation technique, a significant increase (decrease) in the EBITDA multiple in isolation could result in a significantly higher (lower) fair value measurement. Investments in Funds That Are Measured at Net Asset Value Per Share Investments at fair value include investments in funds that are measured at NAV. The Company uses NAV to measure the fair value of its fund investments when (i) the fund investment does not have a readily determinable fair value and (ii) the NAV of the investment fund is calculated in a manner consistent with the measurement principles of investment company accounting, including measurement of the underlying investments at fair value. The Company adopted ASU No. 2015-07 in January 2016 and, as required, disclosures in the paragraphs and tables below are limited to only those investments in funds that are measured at NAV. In accordance with ASU No. 2015-07, previously reported amounts have been conformed to the current presentation. The Company’s investments in funds measured at NAV include private company investments, partnership interests, mutual funds, private equity funds, and money market funds. Private equity funds primarily invest in a broad range of industries worldwide in a variety of situations, including leveraged buyouts, recapitalizations, growth investments and distressed investments. The private equity funds are primarily closed-end funds in which the Company’s investments are generally not eligible for redemption. Distributions will be received from these funds as the underlying assets are liquidated or distributed. The general and limited partnership interests in investment partnerships were primarily valued based upon NAVs received from third-party fund managers. The various partnerships are investment companies, which record their underlying investments at fair value based on fair value policies established by management of the underlying fund. Fair value policies at the underlying fund generally require the funds to utilize pricing/valuation information, including independent appraisals, from third-party sources. However, in some instances, current valuation information for illiquid securities or securities in markets that are not active may not be available from any third-party source or fund management may conclude that the valuations that are available from third-party sources are not reliable. In these instances, fund management may perform model-based analytical valuations that may be used as an input to value these investments. The tables below present the fair value of our investments in, and unfunded commitments to, funds that are measured at NAV (in thousands): June 30, 2016 Fair value of investments Unfunded commitments Private company investments $ 28,639 $ 10,561 Partnership interests 20,962 1,822 Mutual funds 12,857 — Private equity funds 12,109 9,337 Money market funds 9,822 — Total $ 84,389 $ 21,720 December 31, 2015 Fair value of investments Unfunded commitments Private company investments $ 34,385 $ 14,178 Partnership interests 22,502 2,018 Mutual funds 20,399 — Private equity funds 12,970 9,352 Money market funds 77,097 — Total $ 167,353 $ 25,548 Financial Instruments Sold, But Not Yet Purchased Financial instruments sold, but not purchased, recorded at fair value based on quoted prices in active markets and other observable market data include highly liquid instruments with quoted prices, such as U.S. government securities, corporate fixed income securities, and equity securities listed in active markets, which are reported as Level 1. If quoted prices are not available, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include U.S. government agency securities, mortgage-backed securities not actively traded, corporate fixed income and equity securities, and state and municipal securities. Derivatives Derivatives are valued using quoted market prices for identical instruments when available or pricing models based on the net present value of estimated future cash flows. The valuation models used require market observable inputs, including contractual terms, market prices, yield curves, credit curves, and measures of volatility. We manage credit risk for our derivative positions on a counterparty-by-counterparty basis and calculate credit valuation adjustments, included in the fair value of these instruments, on the basis of our relationships at the counterparty portfolio/master netting agreement level. These credit valuation adjustments are determined by applying a credit spread for the counterparty to the total expected exposure of the derivative after considering collateral and other master netting arrangements. We have classified our interest rate swaps as Level 2.

The table above does not present Level 1 or Level 2 valued assets or liabilities. The changes to our company’s Level 3 classified instruments during the six months ended June 30, 2016 were principally a result of purchases of partnership interests. The changes in unrealized gains/(losses) recorded in earnings for the three and six months ended June 30, 2016, relating to Level 3 assets still held at June 30, 2016, were immaterial. The following table summarizes quantitative information related to the significant unobservable inputs utilized in our company’s Level 3 recurring fair value measurements as of June 30, 2016. Valuation technique Unobservable input Range Weighted average Investments: Auction rate securities: Equity securities Discounted cash flow Discount rate 1.7 - 11.7% 5.8% Workout period 1 - 3 years 2.5 years Municipal securities Discounted cash flow Discount rate 0.0 - 10.3% 4.9% Workout period 1 - 4 years 2.1 years The fair value of certain Level 3 assets was determined using various methodologies, as appropriate, including third-party pricing vendors and broker quotes. These inputs are evaluated for reasonableness through various procedures, including due diligence reviews of third-party pricing vendors, variance analyses, consideration of current market environment, and other analytical procedures. The fair value for our auction rate securities was determined using an income approach based on an internally developed discounted cash flow model. The discounted cash flow model utilizes two significant unobservable inputs: discount rate and workout period. The discount rate was calculated using credit spreads of the underlying collateral or similar securities. The workout period was based on an assessment of publicly available information on efforts to re-establish functioning markets for these securities and our company’s own redemption experience. Significant increases in any of these inputs in isolation would result in a significantly lower fair value. On an ongoing basis, management verifies the fair value by reviewing the appropriateness of the discounted cash flow model and its significant inputs. Transfers Within the Fair Value Hierarchy We assess our financial instruments on a quarterly basis to determine the appropriate classification within the fair value hierarchy. Transfers between fair value classifications occur when there are changes in pricing observability levels. Transfers of financial instruments among the levels are deemed to occur at the beginning of the reporting period. The transfers of financial assets from Level 2 to Level 1 during the three months ended June 30, 2016 were immaterial. There were $1.2 million of transfers of financial assets from Level 2 to Level 1 during the six months ended June 30, 2016 primarily related to corporate fixed income securities for which market trades were observed that provided transparency into the valuation of these assets. There were $2.2 million and $2.5 million of transfers of financial assets from Level 1 to Level 2 during the three and six months ended June 30, 2016, respectively, primarily related to corporate fixed income securities for which there were low volumes of recent trade activity observed. There were $0.5 million of transfers into Level 3 during the three months ended June 30, 2016.

Financial Assets Securities Purchased Under Agreements to Resell Securities purchased under agreements to resell are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at June 30, 2016 and December 31, 2015 approximate fair value due to their short-term nature. Held-to-Maturity Securities Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency mortgage-backed securities, asset-backed securities, consisting of corporate obligations, collateralized debt obligation securities, and corporate fixed income securities. The estimated fair value, included in the above table, is determined using several factors; however, primary weight is given to discounted cash flow modeling techniques that incorporated an estimated discount rate based upon recent observable debt security issuances with similar characteristics. Loans Held for Sale Loans held for sale consist of fixed-rate and adjustable-rate residential real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Bank Loans The fair values of mortgage loans and commercial loans were estimated using a discounted cash flow method, a form of the income approach. Discount rates were determined considering rates at which similar portfolios of loans would be made under current conditions and considering liquidity spreads applicable to each loan portfolio based on the secondary market. Financial Liabilities Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at June 30, 2016 and December 31, 2015 approximate fair value due to the short-term nature. Bank Deposits The fair value of interest-bearing deposits, including certificates of deposits, demand deposits, savings, and checking accounts, was calculated by discounting the future cash flows using discount rates based on the replacement cost of funding of similar structures and terms. Borrowings The carrying amount of borrowings approximates fair value due to the relative short-term nature of such borrowings. In addition, Stifel Bank’s FHLB advances reflect terms that approximate current market rates for similar borrowings. Senior Notes The fair value of our senior notes is estimated based upon quoted market prices. Debentures to Stifel Financial Capital Trusts The fair value of our trust preferred securities is based on the discounted value of contractual cash flows. We have assumed a discount rate based on the coupon achieved in our 5.375% senior notes due 2022. These fair value disclosures represent our best estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding future expected losses, current economic conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in the above methodologies and assumptions could significantly affect the estimates.

During the three and six months ended June 30, 2016, there were no sales of available-for-sale securities. For the three and six months ended June 30, 2015, we received proceeds of $552.6 million, respectively, from the sale of available-for-sale securities, which resulted in net realized gains of $3.1 million, respectively. During the three months ended June 30, 2016, unrealized gains, net of deferred taxes, of $11.4 million were recorded in accumulated other comprehensive loss in the consolidated statements of financial condition. During the three months ended June 30, 2015, unrealized losses, net of deferred taxes, of $3.3 million were recorded in accumulated other comprehensive loss in the consolidated statements of financial condition. During the six months ended June 30, 2016, unrealized gains, net of deferred taxes, of $10.4 million were recorded in accumulated other comprehensive loss in the consolidated statements of financial condition. During the six months ended June 30, 2015, unrealized gains, net of deferred taxes, of $3.6 million were recorded in accumulated other comprehensive loss in the consolidated statements of financial condition. The table below summarizes the amortized cost and fair values of debt securities by contractual maturity. Expected maturities may differ significantly from contractual maturities, as issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

At June 30, 2016 and December 31, 2015, securities and loans of $2.6 billion and $1.4 billion, respectively, were pledged at the Federal Home Loan Bank as collateral for borrowings and letters of credit obtained to secure public deposits. At June 30, 2016 and December 31, 2015, securities of $1.5 billion and $1.1 billion, respectively, were pledged with the Federal Reserve discount window.

The total fair value of these investments at June 30, 2016, was $804.7 million, which was 32.6% of our available-for-sale portfolio. At June 30, 2016, the carrying value of 19 securities held to maturity exceeded their fair value by $2.3 million, of which $1.2 million related to securities held to maturity that have been in a loss position for 12 months or longer. As discussed in more detail below, we conduct periodic reviews of all securities with unrealized losses to assess whether the impairment is other-than-temporary. Other-Than-Temporary Impairment We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. There was no credit-related OTTI recognized during the three and six months ended June 30, 2016 and 2015. We believe the gross unrealized losses of $12.5 million related to our investment portfolio, as of June 30, 2016, are attributable to issuer-specific credit spreads and changes in market interest rates and asset spreads. We, therefore, do not expect to incur any credit losses related to these securities. In addition, we have no intent to sell these securities with unrealized losses, and it is not more likely than not that we will be required to sell these securities prior to recovery of the amortized cost. Accordingly, we have concluded that the impairment on these securities is not other-than-temporary.

Bank Loans	NOTE 7 – Bank Loans Our loan portfolio consists primarily of the following segments: Securities-based loans. Securities-based loans allow clients to borrow money against the value of qualifying securities for any suitable purpose other than purchasing, trading, or carrying securities or refinancing margin debt. The majority of consumer loans are structured as revolving lines of credit and letter of credit facilities and are primarily offered through Stifel’s Pledged Asset ("SPA") program. The allowance methodology for securities-based lending considers the collateral type underlying the loan, including the liquidity and trading volume of the collateral, position concentration and other borrower specific factors such as personal guarantees. Commercial and industrial (C&I). C&I loans primarily include commercial and industrial lending used for general corporate purposes, working capital and liquidity, and “event-driven." “Event-driven” loans support client merger, acquisition or recapitalization activities. C&I lending is structured as revolving lines of credit, letter of credit facilities, term loans and bridge loans. Risk factors considered in determining the allowance for corporate loans include the borrower’s financial strength, seniority of the loan, collateral type, leverage, volatility of collateral value, debt cushion, and covenants. Real Estate. Real estate loans include commercial real estate, residential real estate non-conforming loans, residential real estate conforming loans and home equity lines of credit. The allowance methodology real estate loans considers several factors, including, but not limited to, loan-to-value ratio, FICO score, home price index, delinquency status, credit limits, and utilization rates. Consumer. Consumer loans allow customers to purchase non-investment goods and services. Construction and land. Short-term loans used to finance the development of a real estate project.

At June 30, 2016 and December 31, 2015, we had mortgage loans held for sale of $250.7 million and $189.9 million, respectively. For the three months ended June 30, 2016 and 2015, we recognized gains of $4.1 million and $3.5 million, respectively, from the sale of originated loans, net of fees and costs.

If our assumptions prove to be incorrect, our current allowance may not be sufficient to cover future loan losses and we may experience significant increases to our provision. There are two components of the allowance for loan losses: the inherent allowance component and the specific allowance component. The inherent allowance component of the allowance for loan losses is used to estimate the probable losses inherent in the loan portfolio and includes non-homogeneous loans that have not been identified as impaired and portfolios of smaller balance homogeneous loans. The Company maintains methodologies by loan product for calculating an allowance for loan losses that estimates the inherent losses in the loan portfolio. Qualitative and environmental factors such as economic and business conditions, nature and volume of the portfolio and lending terms, and volume and severity of past due loans may also be considered in the calculations. The allowance for loan losses is maintained at a level reasonable to ensure that it can adequately absorb the estimated probable losses inherent in the portfolio. The specific allowance component of the allowance for loan losses is used to estimate probable losses for non-homogeneous exposures, including loans modified in a Troubled Debt Restructuring (“TDR”), which have been specifically identified for impairment analysis by the Company and determined to be impaired. At June 30, 2016, we had $35.1 million of impaired loans, net of discounts, which included $0.2 million in troubled debt restructurings, for which there was a specific allowance of $2.7 million. At December 31, 2015, we had $1.1 million of impaired loans, net of discounts, which included $0.3 million in troubled debt restructurings, for which there was a specific allowance of $0.2 million.

Credit quality indicators Loans meet the definition of Pass when they are performing and/or do not demonstrate adverse characteristics that are likely to result in a credit loss. A loan is determined to be impaired when principal or interest becomes 90 days past due or when collection becomes uncertain. At the time a loan is determined to be impaired, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”), and any accrued and unpaid interest income is reversed. We closely monitor economic conditions and loan performance trends to manage and evaluate our exposure to credit risk. Trends in delinquency ratios are an indicator, among other considerations, of credit risk within our loan portfolios. The level of nonperforming assets represents another indicator of the potential for future credit losses. Accordingly, key metrics we track and use in evaluating the credit quality of our loan portfolio include delinquency and nonperforming asset rates, as well as charge-off rates and our internal risk ratings of the loan portfolio. In general, we are a secured lender. At June 30, 2016 and December 31, 2015, 97.2 % and 97.2% of our loan portfolio was collateralized, respectively. Collateral is required in accordance with the normal credit evaluation process based upon the creditworthiness of the customer and the credit risk associated with the particular transaction. The Company uses the following definitions for risk ratings: Pass. A credit exposure rated pass has a continued expectation of timely repayment, all obligations of the borrower are current, and the obligor complies with material terms and conditions of the lending agreement. Special Mention. Extensions of credit that have potential weakness that deserve management’s close attention, and if left uncorrected may, at some future date, result in the deterioration of the repayment prospects or collateral position. Substandard. Obligor has a well-defined weakness that jeopardizes the repayment of the debt and has a high probability of payment default with the distinct possibility that the Company will sustain some loss if noted deficiencies are not corrected. Doubtful. Inherent weakness in the exposure makes the collection or repayment in full, based on existing facts, conditions and circumstances, highly improbable, and the amount of loss is uncertain. Doubtful loans are considered impaired. Substandard loans are regularly reviewed for impairment. When a loan is impaired the impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or as a practical expedient, the observable market price of the loan or the fair value of the collateral if the loan is collateral dependent. Based on the most recent analysis performed, the risk category of our loan portfolio was as follows: (in thousands) As of June 30, 2016 Pass Special Substandard Doubtful Total Commercial and industrial $ 1,379,608 $ 12,346 $ 32,717 $ — $ 1,424,671 Securities-based loans 1,418,986 — — — 1,418,986 Consumer 36,606 3 17 — 36,626 Residential real estate 1,227,741 74 419 — 1,228,234 Commercial real estate 74,800 — 8,828 — 83,628 Home equity lines of credit 13,833 — 323 — 14,156 Construction and land 7,762 — — — 7,762 Total $ 4,159,336 $ 12,423 $ 42,304 $ — $ 4,214,063 As of December 31, 2015 Pass Special Substandard Doubtful Total Commercial and industrial $ 1,191,030 $ 11,320 $ 14,306 $ — $ 1,216,656 Securities-based loans 1,388,939 — 14 — 1,388,953 Consumer 36,846 — — — 36,846 Residential real estate 427,950 1,182 — — 429,132 Commercial real estate 92,623 — — — 92,623 Home equity lines of credit 12,456 — 19 — 12,475 Construction and land 3,899 — — — 3,899 Total $ 3,153,743 $ 12,502 $ 14,339 $ — $ 3,180,584

Short Term Debt Other Disclosures [Abstract]
Borrowings and Federal Home Loan Bank Advances	NOTE 9 – Borrowings and Federal Home Loan Bank Advances Our short-term financing is generally obtained through short-term bank line financing on an uncommitted, secured basis, committed bank line financing on an unsecured basis, advances from the Federal Home Loan Bank, term loans, and securities lending arrangements. We borrow from various banks on a demand basis with company-owned and customer securities pledged as collateral. The value of customer-owned securities used as collateral is not reflected in the consolidated statements of financial condition. The following table details the components of borrowings (in thousands) June 30, 2016 December 31, 2015 Borrowings on secured lines of credit $ 283,200 $ 30,000 Term loans 51,957 59,084 $ 335,157 89,084 Our uncommitted secured lines of credit at June 30, 2016, totaled $980.0 million with six banks and are dependent on having appropriate collateral, as determined by the bank agreements, to secure an advance under the line. The availability of our uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. Our peak daily borrowing on our uncommitted secured lines was $525.7 million during the three months ended June 30, 2016. There are no compensating balance requirements under these arrangements. Any borrowings on secured lines of credit are generally utilized to finance certain fixed income securities. At June 30, 2016, our uncommitted secured lines of credit were collateralized by company-owned securities valued at $629.0 million. Our committed bank line financing at June 30, 2016, consisted of a $100.0 million revolving credit facility. The credit facility expires in December 2017. The applicable interest rate under the revolving credit facility is calculated as a per annum rate equal to the London Interbank Offered Rate (“LIBOR”) plus 2.00%, as defined in the revolving credit facility. At June 30, 2016, we had no advances on our revolving credit facility and were in compliance with all covenants. The Federal Home Loan advances as of June 30, 2016 are floating-rate advances. The weighted average interest rates on these advances during the three months ended June 30, 2016 was 1.32%. The advances are secured by Stifel Bank’s residential mortgage loan portfolio and investment portfolio. The interest rates reset on a daily basis. Stifel Bank has the option to prepay these advances without penalty on the interest reset date. As of June 30, 2016, a subsidiary of the Parent was a party to two Term Loans (“Term Loans”). The Term Loans mature on August 3, 2016. The interest rate under the Amended and Restated Credit Agreement is calculated as a per annum rate equal to LIBOR, as defined. During the three months ended June 30, 2016, the weighted average interest rate on these term loans was 1.96%. The Term Loans were paid-off in July 2016.

General Discussion Of Derivative Instruments And Hedging Activities [Abstract]
Derivative Instruments And Hedging Activities	NOTE 12 – Derivative Instruments and Hedging Activities We use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps generally involve the exchange of fixed and variable rate interest payments between two parties, based on a common notional principal amount and maturity date with no exchange of underlying principal amounts. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for our company making fixed payments. Our policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements. The following table provides the notional values and fair values of our derivative instruments as of June 30, 2016 and December 31, 2015 (in thousands) June 30, 2016 Asset Derivatives Liability Derivatives Notional Balance Location Positive Fair Value Balance Location Negative Fair Value Derivatives designated as hedging instruments under Topic 815: Cash flow interest rate contracts $ 936,507 Other assets $ — Accounts payable and accrued expenses $ (17,707 ) December 31, 2015 Asset Derivatives Liability Derivatives Notional Value Balance Location Positive Fair Value Balance Sheet Location Negative Fair Value Derivatives designated as hedging instruments under Topic 815: Cash flow interest rate contracts $ 179,110 Other assets $ — Accounts payable and accrued expenses $ (3,591 ) Cash Flow Hedges We have entered into interest rate swap agreements that effectively modify our exposure to interest rate risk by converting floating rate debt to a fixed rate debt. The swaps have an average remaining life of [2.7] years. Any unrealized gains or losses related to cash flow hedging instruments are reclassified from accumulated other comprehensive loss into earnings in the same period the hedged forecasted transaction affects earnings and are recorded in interest expense on the accompanying consolidated statements of operations. The ineffective portion of the cash flow hedging instruments is recorded in other income or other operating expense. The loss recognized during the three and six months ended June 30, 2016 and 2015, respectively, related to ineffectiveness was insignificant. Amounts reported in accumulated other comprehensive loss related to derivatives will be reclassified to interest expense as interest payments are made on our variable rate deposits. During the next twelve months, we estimate that $6.0 million will be reclassified as an increase to interest expense. The following table shows the effect of our company’s derivative instruments in the consolidated statements of operations for the three and six months ended June 30, 2016 and 2015 (in thousands) Three Months Ended June 30, 2016 Gain/(Loss) Recognized in OCI (Effectiveness) Location of Loss Reclassified From OCI Into Income Loss Reclassified From OCI Into Income Location of Loss Recognized in OCI (Ineffectiveness) Loss Recognized Due to Ineffectiveness Cash flow interest rate contracts $ (7,099 ) Interest expense $ 1,537 None $ 33 Three Months Ended June 30, 2015 Gain/(Loss) Recognized in OCI (Effectiveness) Location of Loss Reclassified From OCI Into Income Loss Reclassified From OCI Into Income Location of Loss Recognized in OCI (Ineffectiveness) Loss Recognized Due to Ineffectiveness Cash flow interest rate contracts $ 124 Interest $ 1,046 None $ — Six Months Ended June 30, 2016 Gain/(Loss) Recognized in OCI (Effectiveness) Location of Loss Reclassified From OCI Into Income Loss Reclassified From OCI Into Income Location of Loss Recognized in OCI (Ineffectiveness) Loss Recognized Due to Ineffectiveness Cash flow interest rate contracts $ (16,525 ) Interest $ 2,882 None $ 46 Six Months Ended June 30, 2015 Gain/(Loss) Recognized in OCI (Effectiveness) Location of Loss Reclassified From OCI Into Income Loss Reclassified From OCI Into Income Location of Loss Recognized in OCI (Ineffectiveness) Loss Recognized Due to Ineffectiveness Cash flow interest rate contracts $ (1,399 ) Interest expense $ 2,207 None $ — We maintain a risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings caused by interest rate volatility. Our goal is to manage sensitivity to changes in rates by hedging the maturity characteristics of variable rate affiliated deposits, thereby limiting the impact on earnings. By using derivative instruments, we are exposed to credit and market risk on those derivative positions. We manage the market risk associated with interest rate contracts by establishing and monitoring limits as to the types and degree of risk that may be undertaken. Credit risk is equal to the extent of the fair value gain in a derivative if the counterparty fails to perform. When the fair value of a derivative contract is positive, this generally indicates that the counterparty owes our company and, therefore, creates a repayment risk for our company. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, have no repayment risk. See Note 4 in the notes to our consolidated financial statements for further discussion on how we determine the fair value of our financial instruments. We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by senior management. Credit Risk-Related Contingency Features We have agreements with our derivative counterparties containing provisions where if we default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations. We have agreements with certain of our derivative counterparties that contain provisions where if our shareholders’ equity declines below a specified threshold or if we fail to maintain a specified minimum shareholders’ equity, then we could be declared in default on our derivative obligations. Certain of our agreements with our derivative counterparties contain provisions where if a specified event or condition occurs that materially changes our creditworthiness in an adverse manner, we may be required to fully collateralize our obligations under the derivative instrument. Regulatory Capital-Related Contingency Features Certain of our derivative instruments contain provisions that require us to maintain our capital adequacy requirements. If we were to lose our status as “adequately capitalized,” we would be in violation of those provisions, and the counterparties of the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions. As of June 30, 2016, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $17.7 million (termination value). We have minimum collateral posting thresholds with certain of our derivative counterparties and have posted cash collateral of $19.6 million against our obligations under these agreements. If we had breached any of these provisions at June 30, 2016, we would have been required to settle our obligations under the agreements at the termination value. Counterparty Risk In the event of counterparty default, our economic loss may be higher than the uncollateralized exposure of our derivatives if we were not able to replace the defaulted derivatives in a timely fashion. We monitor the risk that our uncollateralized exposure to each of our counterparties for interest rate swaps will increase under certain adverse market conditions by performing periodic market stress tests. These tests evaluate the potential additional uncollateralized exposure we would have to each of these derivative counterparties assuming changes in the level of market rates over a brief time period.

Loss Contingency [Abstract]
Commitments, Guarantees, And Contingencies	NOTE 14 – Commitments, Guarantees, and Contingencies Broker-Dealer Commitments and Guarantees In the normal course of business, we enter into underwriting commitments. Settlement of transactions relating to such underwriting commitments, which were open at June 30, 2016, had no material effect on the consolidated financial statements. We also provide guarantees to securities clearinghouses and exchanges under their standard membership agreement, which requires members to guarantee the performance of other members. Under the agreement, if another member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet shortfalls. Our liability under these agreements is not quantifiable and may exceed the cash and securities we have posted as collateral. However, the potential requirement for us to make payments under these arrangements is considered remote. Accordingly, no liability has been recognized for these arrangements. Other Commitments In the ordinary course of business, Stifel Bank has commitments to extend credit in the form of commitments to originate loans, standby letters of credit, and lines of credit. See Note 19 in the notes to consolidated financial statements for further details. We have committed capital to certain entities, and these commitments generally have no specified call dates. We had $21.7 million of commitments outstanding at June 30, 2016, of which $10.6 million relate to commitments to certain strategic relationships with Business Development Corporations. Concentration of Credit Risk We provide investment, capital-raising, and related services to a diverse group of domestic customers, including governments, corporations, and institutional and individual investors. Our exposure to credit risk associated with the non-performance of customers in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile securities markets, credit markets, and regulatory changes. This exposure is measured on an individual customer basis and on a group basis for customers that share similar attributes. To reduce the potential for risk concentrations, counterparty credit limits have been implemented for certain products and are continually monitored in light of changing customer and market conditions. As of June 30, 2016 and December 31, 2015, we did not have significant concentrations of credit risk with any one customer or counterparty, or any group of customers or counterparties.

Loss Contingency Information About Litigation Matters [Abstract]
Legal Proceedings	NOTE 15 – Legal Proceedings Our company and its subsidiaries are named in and subject to various proceedings and claims arising primarily from our securities business activities, including lawsuits, arbitration claims, class actions, and regulatory matters. Some of these claims seek substantial compensatory, punitive, or indeterminate damages. Our company and its subsidiaries are also involved in other reviews, investigations, and proceedings by governmental and self-regulatory organizations regarding our business, which may result in adverse judgments, settlements, fines, penalties, injunctions, and other relief. We are contesting the allegations in these claims, and we believe that there are meritorious defenses in each of these lawsuits, arbitrations, and regulatory investigations. In view of the number and diversity of claims against our company, the number of jurisdictions in which litigation is pending, and the inherent difficulty of predicting the outcome of litigation and other claims, we cannot state with certainty what the eventual outcome of pending litigation or other claims will be. We have established reserves for potential losses that are probable and reasonably estimable that may result from pending and potential legal actions, investigations, and regulatory proceedings. In many cases, however, it is inherently difficult to determine whether any loss is probable or even possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages or where plaintiffs are seeking substantial or indeterminate damages. Matters frequently need to be more developed before a loss or range of loss can reasonably be estimated. In our opinion, based on currently available information, review with outside legal counsel, and consideration of amounts provided for in our consolidated financial statements with respect to these matters, including the matters described below, the ultimate resolution of these matters will not have a material adverse impact on our financial position and results of operations. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. For matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which an exposure to loss in excess of the amount accrued is reasonably possible, based on currently available information, we believe that such losses will not have a material effect on our consolidated financial statements. SEC/Wisconsin Lawsuit A civil lawsuit was filed against our company by the SEC in connection with our role in the sale of collateralized debt obligations (“CDOs”) investments to five Southeastern Wisconsin school districts (the “school districts”) in U.S. District Court for the Eastern District of Wisconsin on August 10, 2011. The SEC has asserted claims under Section 15c(1) (A), Section 10b and Rule 10b-5 of the Exchange Act and Sections 17a(1), 17a(2), and 17a(3) of the Securities Act. The claims are based upon both alleged misrepresentations and omissions in connection with the sale of the CDOs to the school districts, as well as the allegedly unsuitable nature of the CDOs. We answered, denied the substantive allegations of the amended complaint, and asserted various affirmative defenses. In January 2016, the parties filed motions for summary judgment and are awaiting the court’s rulings on those motions. The trial is currently scheduled to commence on September 12, 2016. While there can be no assurance that we will be successful, we intend to vigorously defend the claims. EDC Bond Issuance Matter We have been named, along with other parties, in a lawsuit filed in Wisconsin state court asserting various claims by LDF Acquisition LLC (“LDF”), a special purpose vehicle created by Saybrook Tax Exempt Investors LLC (collectively “Saybrook”) and by the Lac Du Flambeau Band of Lake Superior Chippewa Indians and its Lake of the Torches Economic Development Corporation (the “Tribe”) in which, among other things, Saybrook seeks repayment from the Tribe for the proceeds from a $50 million 2008 bond offering (“the bonds’) and in which the Tribe seeks to avoid repayment, as well as other claims against us and others. We were the initial purchaser of the bonds, which were immediately sold to LDF. The claims asserted against Stifel are for breaches of implied warranties of validity and title, securities fraud and statutory misrepresentation under Wisconsin state law, intentional and negligent misrepresentations relating to those matters. Saybrook seeks rescissionary relief as well as restitutionary damages, including the amounts paid for the bonds, plus costs. The claims have been bifurcated by the Court, with the first phase of the trial currently scheduled to commence on October 17, 2016, and a second phase to commence on January 30, 2017. While there can be no assurance that we will be successful, we intend to vigorously defend the claims. Broyles, et al. v. Cantor Fitzgerald & Co. et al. Matter Our company, Stifel, and Stone & Youngberg, LLC (“Stone & Youngberg”) are named in an Amended Complaint filed in U.S. District Court for the Middle District of Louisiana alleging fraud on the part of Stone & Youngberg in the formation of the Collybus CDO manufactured by Cantor Fitzgerald & Co. (“Cantor”) and purchased by Commonwealth Advisors (“CWA”) on behalf of several CA funds, as well as in connection with other transactions in the CA funds with CWA, and asserting claims against our company and Stifel for successor and alter ego liability. The original Complaint named Cantor, CA, and CA’s CEO, Walter Morales. The CA funds filed a Chapter 11 bankruptcy petition which stayed the original lawsuit until the reorganization plan was entered by the court in the fall of 2013. Shortly thereafter, the CA funds filed their first Amended Complaint, which has been amended several times since then. The claims are set for trial commencing on November 28, 2016. While there can be no assurance that we will be successful, we intend to vigorously defend the claims. We have established reserves supported by purchase price consideration the Company has withheld pursuant to the terms of the acquisition of Stone & Youngberg in 2011, which at this time, we believe are adequate.

Regulatory Capital Requirements

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements	NOTE 16 – Regulatory Capital Requirements We operate in a highly regulated environment and are subject to capital requirements, which may limit distributions to our company from its subsidiaries. Distributions from our broker-dealer subsidiaries are subject to net capital rules. A broker-dealer that fails to comply with the SEC’s Uniform Net Capital Rule (Rule 15c3-1) may be subject to disciplinary actions by the SEC and self-regulatory organizations, such as FINRA, including censures, fines, suspension, or expulsion. Stifel has chosen to calculate its net capital under the alternative method, which prescribes that their net capital shall not be less than the greater of $1.0 million or two percent of aggregate debit balances (primarily receivables from customers) computed in accordance with the SEC’s Customer Protection Rule (Rule 15c3-3). Our other broker-dealer subsidiaries calculate their net capital under the aggregate indebtedness method, whereby their aggregate indebtedness may not be greater than fifteen times their net capital (as defined). At June 30, 2016, Stifel had net capital of $268.3 million, which was 16.8% of aggregate debit items and $236.4 million in excess of its minimum required net capital. At June 30, 2016, all of our other broker-dealer subsidiaries’ net capital exceeded the minimum net capital required under the SEC rule. Our international subsidiary is subject to the regulatory supervision and requirements of the Financial Conduct Authority (“FCA”) in the United Kingdom. At June 30, 2016, our international subsidiary’s capital and reserves were in excess of the financial resources requirement under the rules of the FCA. Our company, as a bank holding company, and Stifel Bank are subject to various regulatory capital requirements administered by the Federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our company’s and Stifel Bank’s financial results. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, our company and Stifel Bank must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Our company’s and Stifel Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Our company and Stifel Bank are subject to Basel III. Under the Basel III rules, the quantity and quality of regulatory capital increased, a capital conservation buffer was established, selected changes were made to the calculation of risk-weighted assets, and a new ratio, common equity Tier 1 was introduced, all of which are applicable to both our company and Stifel Bank. Various aspects of Basel III will be subject to multi-year transition periods through December 31, 2018. Our company and Stifel Bank are required to maintain minimum amounts and ratios of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), Tier 1 capital to average assets (as defined), and under rules defined in Basel III, Common equity Tier 1 capital to risk-weighted assets. Our company and Stifel Bank each calculate these ratios in order to assess compliance with both regulatory requirements and their internal capital policies. At current capital levels, our company and Stifel Bank are each categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” our company and Stifel Bank must maintain total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the tables below (in thousands, except ratios).

Share Based Compensation Allocation And Classification In Financial Statements [Abstract]
Employee Incentive, Deferred Compensation, And Retirement Plans	NOTE 18 – Employee Incentive, Deferred Compensation, and Retirement Plans We maintain several incentive stock award plans that provide for the granting of stock options, stock appreciation rights, restricted stock, performance award, stock units and debentures to our employees. We are permitted to issue new shares under all stock award plans approved by shareholders or to reissue our treasury shares. Awards under our company’s incentive stock award plans are granted at market value at the date of grant. The awards generally vest ratably over a three- to nine-year vesting period. All stock-based compensation plans are administered by the Compensation Committee of the Board of Directors (“Compensation Committee”), which has the authority to interpret the plans, determine to whom awards may be granted under the plans, and determine the terms of each award. According to these plans, we are authorized to grant an additional 6.2 million shares at June 30, 2016. Stock-based compensation expense included in compensation and benefits expense in the consolidated statements of operations for our company’s incentive stock award plans was $65.9 million and $50.4 million for the three months ended June 30, 2016 and 2015, respectively. The tax impact related to stock-based compensation recognized in shareholders’ equity was a provision of $1.0 million and a benefit of $1.4 million for the three months ended June 30, 2016 and 2015, respectively. Stock-based compensation expense included in compensation and benefits expense in the consolidated statements of operations for our company’s incentive stock award plans was $94.8 million and $78.0 million for the six months ended June 30, 2016 and 2015, respectively. The tax benefit related to stock-based compensation recognized in shareholders’ equity was a provision of $5.2 million and a benefit of $13.2 million for the six months ended June 30, 2016 and 2015, respectively. On June 30, 2016, the Company’s Board of Directors removed the continuing service requirements associated with restricted stock units that were granted to certain employees of Barclays in December 2015. As a result of the modification, the awards were expensed at date of modification resulting in a charge of $36.0 million during the second quarter of 2016. The fair value of the awards is based upon the closing price of our company’s common stock on the date of the grant of the awards. This charge is included in compensation and benefits in the consolidated statement of operations for the three and six months ended June 30, 2016. Stock Units A stock unit represents the right to receive a share of common stock from our company at a designated time in the future without cash payment by the employee and is issued in lieu of cash incentive, principally for deferred compensation and employee retention plans. The restricted stock units vest on an annual basis over the next one to nine years and are distributable, if vested, at future specified dates. The Company began granting Performance-based Restricted Stock Units (“PRSUs”) to its executive officers in 2016. Under the terms of the grants, the number of PRSUs that will vest and convert to shares will be based on the Company's achievement of the pre-determined performance objectives during the performance period. The PRSUs will be measured over a 4-year performance period and vested over a 5-year period. The number of shares converted has the potential to range from 0% to 200% based on how the Company performs during the performance period. Compensation expense is amortized on a straight-line basis over the service period based on the fair value of the award on the grant date. The Company’s pre-determined performance objectives must be met for the awards to vest. Employees forfeit unvested share units upon termination of employment with a corresponding reversal of compensation expense. At June 30, 2016, the total number of stock units outstanding was 21.3 million, of which 17.5 million were unvested. At June 30, 2016, the total number of performance-based restricted stock units was 0.5 million, of which all were unvested. At June 30, 2016, there was unrecognized compensation cost for stock units of approximately $423.0 million, which is expected to be recognized over a weighted-average period of 3.1 years. Deferred Compensation Plans The Wealth Accumulation Plan (the “Plan”) is provided to certain revenue producers, officers, and key administrative employees, whereby a certain percentage of their incentive compensation is deferred as defined by the Plan into company stock units and debentures. Participants may elect to defer a portion of their incentive compensation. Deferred awards generally vest over a three- to nine-year period and are distributable upon vesting or at future specified dates. Deferred compensation costs are amortized on a straight-line basis over the vesting period. Elective deferrals are 100% vested. Additionally, the Plan allows Stifel’s financial advisors who achieve certain levels of production to defer a certain percentage of their gross commissions. As stipulated by the Plan, the financial advisors will defer 5% of their gross commissions. They have the option to have up to 3%, of their 5% deferral in mutual funds, which earn a return based on the performance of index mutual funds as designated by our company or a fixed income option. In addition, they can elect to defer an additional 1% of gross commissions into company stock units with a 25% matching contribution. Financial advisors have no ownership in the mutual funds. Included in the investments in the consolidated statements of financial condition are investments in mutual funds of $7.9 million and $15.5 million at June 30, 2016 and December 31, 2015, respectively, that were purchased by our company to economically hedge, on an after-tax basis, its liability to the financial advisors who choose to base the performance of their return on the index mutual fund option. At June 30, 2016 and December 31, 2015, the deferred compensation liability related to the mutual fund option of $6.0 million and $12.4 million, respectively, is included in accrued compensation in the consolidated statements of financial condition. In addition, certain financial advisors, upon joining our company, may receive company stock units in lieu of transition cash payments. Deferred compensation related to these awards generally vests over a five- to nine-year period. Deferred compensation costs are amortized on a straight-line basis over the deferral period. Profit Sharing Plan Eligible employees of our company who have met certain service requirements may participate in the Stifel Financial Corp. Profit Sharing 401(k) Plan (the “401(k) Plan”). Employees are permitted within limitations imposed by tax law to make pre-tax contributions to the 401(k) Plan. We may match certain employee contributions or make additional contributions to the 401(k) Plan at our discretion. Our contributions to the 401(k) Plan were $1.6 million and $1.6 million for the three months ended June 30, 2016 and 2015, respectively and $2.9 million and $2.8 million for the six months ended June 30, 2016 and 2015, respectively.

Off-Balance Sheet Credit Risk

Off-Balance Sheet Credit Risk	6 Months Ended
	Jun. 30, 2016
Concentration Risks Types No Concentration Percentage [Abstract]
Off-Balance Sheet Credit Risk	NOTE 19 – Off-Balance Sheet Credit Risk In the normal course of business, we execute, settle, and finance customer and proprietary securities transactions. These activities expose our company to off-balance sheet risk in the event that customers or other parties fail to satisfy their obligations. In accordance with industry practice, securities transactions generally settle within three business days after trade date. Should a customer or broker fail to deliver cash or securities as agreed, we may be required to purchase or sell securities at unfavorable market prices. We borrow and lend securities to facilitate the settlement process and finance transactions, utilizing customer margin securities held as collateral. We monitor the adequacy of collateral levels on a daily basis. We periodically borrow from banks on a collateralized basis, utilizing firm and customer margin securities in compliance with SEC rules. Should the counterparty fail to return customer securities pledged, we are subject to the risk of acquiring the securities at prevailing market prices in order to satisfy our customer obligations. We control our exposure to credit risk by continually monitoring our counterparties’ positions, and where deemed necessary, we may require a deposit of additional collateral and/or a reduction or diversification of positions. Our company sells securities it does not currently own (short sales) and is obligated to subsequently purchase such securities at prevailing market prices. We are exposed to risk of loss if securities prices increase prior to closing the transactions. We control our exposure to price risk from short sales through daily review and setting position and trading limits. We manage our risks associated with the aforementioned transactions through position and credit limits and the continuous monitoring of collateral. Additional collateral is required from customers and other counterparties when appropriate. We have accepted collateral in connection with resale agreements, securities borrowed transactions, and customer margin loans. Under many agreements, we are permitted to sell or repledge these securities held as collateral and use these securities to enter into securities lending arrangements or to deliver to counterparties to cover short positions. At June 30, 2016 and December 31, 2015, the fair value of securities accepted as collateral where we are permitted to sell or repledge the securities was $2.4 billion and $2.4 billion, respectively, and the fair value of the collateral that had been sold or repledged was $317.0 million and $278.7 million, respectively. We enter into interest rate derivative contracts to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are principally used to manage differences in the amount, timing, and duration of our known or expected cash payments related to certain variable-rate affiliated deposits. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments. Our interest rate hedging strategies may not work in all market environments and, as a result, may not be effective in mitigating interest rate risk. Derivatives’ notional contract amounts are not reflected as assets or liabilities in the consolidated statements of financial condition. Rather, the market or fair value of the derivative transactions are reported in the consolidated statements of financial condition as other assets or accounts payable and accrued expenses, as applicable. For a complete discussion of our activities related to derivative instruments, see Note 12 in the notes to consolidated financial statements. In the ordinary course of business, Stifel Bank has commitments to originate loans, standby letters of credit, and lines of credit. Commitments to originate loans are agreements to lend to a customer as long as there is no violation of any condition established by the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash commitments. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if necessary, is based on the credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate, and residential real estate. At June 30, 2016 and December 31, 2015, Stifel Bank had outstanding commitments to originate loans aggregating $302.4 million and $130.5 million, respectively. The commitments extended over varying periods of time, with all commitments at June 30, 2016, scheduled to be disbursed in the following three months. Through Stifel Bank, in the normal course of business, we originate residential mortgage loans and sell them to investors. We may be required to repurchase mortgage loans that have been sold to investors in the event there are breaches of certain representations and warranties contained within the sales agreements. We may be required to repurchase mortgage loans that were sold to investors in the event that there was inadequate underwriting or fraud, or in the event that the loans become delinquent shortly after they are originated. We also may be required to indemnify certain purchasers and others against losses they incur in the event of breaches of representations and warranties and in various other circumstances, and the amount of such losses could exceed the repurchase amount of the related loans. Consequently, we may be exposed to credit risk associated with sold loans. Standby letters of credit are irrevocable conditional commitments issued by Stifel Bank to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Should Stifel Bank be obligated to perform under the standby letters of credit, it may seek recourse from the customer for reimbursement of amounts paid. At June 30, 2016 and December 31, 2015, Stifel Bank had outstanding letters of credit totaling $37.0 million and $38.7 million, respectively. A majority of the standby letters of credit commitments at June 30, 2016, have expiration terms that are less than one year. Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Stifel Bank uses the same credit policies in granting lines of credit as it does for on-balance sheet instruments. At June 30, 2016 and December 31, 2015, Stifel Bank had granted unused lines of credit to commercial and consumer borrowers aggregating $522.6 million and $403.2 million, respectively.

Segment Reporting Information Profit Loss [Abstract]
Segment Reporting	NOTE 20 – Segment Reporting We currently operate through the following three business segments: Global Wealth Management, Institutional Group, and various corporate activities combined in the Other segment. Our Global Wealth Management segment consists of two businesses, the Private Client Group and Stifel Bank. The Private Client Group includes branch offices and independent contractor offices of our broker-dealer subsidiaries located throughout the United States. These branches provide securities brokerage services, including the sale of equities, mutual funds, fixed income products, and insurance, as well as offering banking products to their clients through Stifel Bank.

Earnings Per Share ("EPS")

Earnings Per Share ("EPS")	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 21 – Earnings Per Share (“EPS”) Basic EPS is computed by dividing earnings available to common shareholders by the weighted-average number of common shares outstanding. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. Diluted earnings per share include dilutive stock options and stock units under the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended June 30, 2016 and 2015 (in thousands, except per share data) Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Net income $ 9,771 $ 20,888 $ 36,826 $ 63,985 Shares for basic and diluted calculation: Average shares used in basic computation 66,792 68,370 67,186 68,189 Dilutive effect of stock options and units (1) 9,190 9,486 8,898 9,435 Average shares used in diluted computation 75,982 77,856 76,084 77,624 Earnings per common share: Basic $ 0.15 $ 0.31 $ 0.55 $ 0.94 Diluted $ 0.13 $ 0.27 $ 0.48 $ 0.82 1 Diluted earnings per share is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings per share include stock options and units. For the three and six months ended June 30, 2016 and 2015, the anti-dilutive effect from restricted stock units was immaterial.

Shareholders' Equity

Shareholders' Equity	6 Months Ended

Equity [Abstract]
Shareholders' Equity	NOTE 22 – Shareholders’ Equity Share Repurchase Program We have an ongoing authorization from the Board of Directors to repurchase our common stock in the open market or in negotiated transactions. At June 30, 2016, the maximum number of shares that may yet be purchased under this plan was 8.0 million. The repurchase program has no expiration date. These purchases may be made on the open market or in privately negotiated transactions, depending upon market conditions and other factors. Repurchased shares may be used to meet obligations under our employee benefit plans and for general corporate purposes. During the three and six months ended June 30, 2016, we repurchased $3.7 million and $95.1 million, or 0.1 million and 2.8 million shares, respectively, using existing Board authorizations at an average price of $29.70 and $33.79 per share, repectively, to meet obligations under our company’s employee benefit plans and for general corporate purposes. There were no repurchases during the three and six months ended June 30, 2015. Issuance of Common Stock On January 4, 2016, we issued 0.3 million shares related to the purchase of Eaton Partners. During the six months ended June 30, 2016, we issued [2.3 million shares, which were reissued from treasury. Share issuances were primarily a result of the vesting and exercise transactions under our incentive stock award plans and shares issued as part of the purchase consideration in our acquisition of Eaton Partners.

Variable Interest Entities

Variable Interest Entities	6 Months Ended
	Jun. 30, 2016
Variable Interest Entity Not Primary Beneficiary Disclosures [Abstract]
Variable Interest Entities	NOTE 23 – Variable Interest Entities Our company’s involvement with VIEs is limited to entities used as investment vehicles and private equity funds, the establishment of Stifel Financial Capital Trusts, and our issuance of a convertible promissory note. We have formed several non-consolidated investment funds with third-party investors that are typically organized as limited liability companies (“LLCs”) or limited partnerships. These partnerships and LLCs have assets of $152.6 million at June 30, 2016. For those funds where we act as the general partner, our company’s economic interest is generally limited to management fee arrangements as stipulated by the fund operating agreements. We have generally provided the third-party investors with rights to terminate the funds or to remove us as the general partner. Management fee revenue earned by our company was insignificant during the three and six months ended June 30, 2016 and 2015. In addition, our direct investment interest in these entities is insignificant at June 30, 2016 and December 31, 2015. Thomas Weisel Capital Management LLC, a subsidiary of our company, acts as the general partner of a series of investment funds in venture capital and fund of funds and manages investment funds that are active buyers of secondary interests in private equity funds, as well as portfolios of direct interests in venture-backed companies. These partnerships have combined assets of $333.2 million at June 30, 2016. We hold variable interests in these funds as a result of our company’s rights to receive management fees. Our company’s investment in and additional capital commitments to the private equity funds are also considered variable interests. The additional capital commitments are subject to call at a later date and are limited in amount. Our exposure to loss is limited to our investments in, advances and commitments to, and receivables due from these funds, and that exposure is insignificant at June 30, 2016. Management fee revenue earned by our company was insignificant during the three and six months ended June 30, 2016 and 2015. For the entities noted above that were determined to be VIEs, we have concluded that we are not the primary beneficiary, and therefore, we are not required to consolidate these entities. Additionally, for certain other entities, we reviewed other relevant accounting guidance, which states the general partner in a limited partnership is presumed to control that limited partnership. The presumption may be overcome if the limited partners have either: (1) the substantive ability to dissolve the limited partnership or otherwise remove the general partner without cause, or (2) substantive participating rights, which provide the limited partners with the ability to effectively participate in significant decisions that would be expected to be made in the ordinary course of the limited partnership’s business and thereby preclude the general partner from exercising unilateral control over the partnership. If the criteria are not met, the consolidation of the partnership or limited liability company is required. Based on our evaluation of these entities, we determined that these entities do not require consolidation. Debenture to Stifel Financial Capital Trusts We have completed private placements of cumulative trust preferred securities through Stifel Financial Capital Trust II, Stifel Financial Capital Trust III, and Stifel Financial Capital Trust IV (collectively, the “Trusts”). The Trusts are non-consolidated wholly owned business trust subsidiaries of our company and were established for the limited purpose of issuing trust securities to third parties and lending the proceeds to our company. The trust preferred securities represent an indirect interest in junior subordinated debentures purchased from our company by the Trusts, and we effectively provide for the full and unconditional guarantee of the securities issued by the Trusts. We make timely payments of interest to the Trusts as required by contractual obligations, which are sufficient to cover payments due on the securities issued by the Trusts, and believe that it is unlikely that any circumstances would occur that would make it necessary for our company to make payments related to these Trusts other than those required under the terms of the debenture agreements and the trust preferred securities agreements. The Trusts were determined to be VIEs because the holders of the equity investment at risk do not have adequate decision-making ability over the Trust’s activities. Our investment in the Trusts is not a variable interest, because equity interests are variable interests only to the extent that the investment is considered to be at risk. Because our investment was funded by the Trusts, it is not considered to be at risk. Interest in FSI Group, LLC (“FSI”) We have provided financing of $18.0 million in the form of a convertible promissory note to FSI, a limited liability company specializing in investing in banks, thrifts, insurance companies, and other financial services firms. In February 2013, the convertible promissory note was amended and restated. The convertible promissory note matures in April 2018; however, FSI has three five-year extension options. The note is convertible at our election into a 49.9% interest in FSI only after the last extension option. The convertible promissory note has a minimum coupon rate equal to 8% per annum plus additional interest related to certain defined cash flows of the business, not to exceed 18% per annum. As we do not hold the power to direct the activities of FSI nor to absorb a majority of the expected losses, or receive a majority of the expected benefits, it was determined that we are not required to consolidate this entity. Our company’s exposure to loss is limited to the carrying value of the note with FSI at June 30, 2016, of $18.0 million, which is included in other assets in the consolidated statements of financial condition. Our company had no liabilities related to this entity at June 30, 2016. We have the discretion to make additional capital contributions. We have not provided financial or other support to FSI that we were not previously contractually required to provide as of June 30, 2016. Our company’s involvement with FSI has not had a material effect on our consolidated financial position, operations, or cash flows.

Subsequent Events [Abstract]
Subsequent Events	NOTE 24 – Subsequent Events We evaluate subsequent events that have occurred after the balance sheet date but before the financial statements are issued. There are two types of subsequent events: (1) recognized, or those that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, and (2) non-recognized, or those that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Based on the evaluation, we did not identify any recognized subsequent events that would have required adjustment to the consolidated financial statements. Based on the evaluation, we identified the following as non-recognized events. Issuance of Senior Notes and Preferred Stock On July 11, 2016, the Company completed the pricing of an additional $200.0 million in aggregate principal amount of the Company’s 2015 Notes. The 2015 Notes mature in July 2024 and bear interest at 4.250%, payable semi-annually in arrears on January 18 and July 18. The 2015 Notes were issued with an effective yield of 4.034%. On July 11, 2016, the Company completed an underwritten registered public offering of $150 million perpetual 6.25% Non-Cumulative Perpetual Preferred Stock, Series A. Sale of Sterne Businesses On July 1, 2016, the Company completed the sale of Sterne Agee, LLC’s legacy independent brokerage and clearing businesses to INTL FCStone Inc. pursuant to two separate stock purchase agreements dated June 24, 2016. The closing of the sale of Sterne Agee, LLC’s legacy RIA business will occur during the third quarter following a customary client notice period. Pursuant to the two stock purchase agreements, the Company agreed to sell Sterne Agee Financial Services, Inc.; Sterne Agee Clearing, Inc.; Sterne Agee & Leach, Inc.; Sterne Agee Asset Management, Inc.; and Sterne Agee Investment Advisor Services, Inc. (the “Sterne Businesses”) for cash consideration equal to approximately $50 million. The related assets and liabilities associated with the Sterne Businesses are classified as held for sale in the consolidated statement of financial condition as of June 30, 2016.

Prospective Adoption Of New Accounting Pronouncements [Abstract]
Nature Of Operations	Nature of Operations Stifel Financial Corp. (the “Company”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. We have offices throughout the United States and Europe. Our major geographic area of concentration is throughout the United States, with a growing presence in Europe. Our company’s principal customers are individual investors, corporations, municipalities, and institutions. On January 4, 2016, the Company completed the acquisition of Eaton Partners, LLC (“Eaton Partners”), a global fund placement and advisory firm. Eaton Partners will retain its brand name and will be run as a Stifel company. The acquisition was funded with cash from operations and our common stock. On May 5, 2016, the Company completed the acquisition of ISM Capital LLP (“ISM”), an independent investment bank focused on international debt capital markets. The acquisition of ISM adds to the Company’s debt capital markets origination, sales and research capabilities in Europe, including an end-to-end platform for convertible securities and other equity-linked debt instruments. The acquisition was funded with cash from operations.
Basis Of Presentation	Basis of Presentation The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Keefe, Bruyette & Woods, Inc., and Stifel Bank & Trust (“Stifel Bank”). All material intercompany balances and transactions have been eliminated. Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries. We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Pursuant to these rules and regulations, we have omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles. In management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise noted) necessary to fairly present our financial position, results of operations and cash flows. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and the notes thereto in our Annual Report on Form 10-K for the year ended December 31, 2015 on file with the SEC. Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material. There have been no material changes in our significant accounting policies, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2015.
Financial Instruments Credit Losses	Financial Instruments – Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The guidance requires that credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. The guidance is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for our Company), including interim periods within that reporting period. Early adoption is permitted for annual periods beginning after December 15, 2018. We are currently evaluating the effect that the new guidance will have on our consolidated financial statements.
Share Based Payments	Share-Based Payments In March 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”) that requires an entity to record all excess tax benefits and tax deficiencies as an income tax benefit or expense in the income statement. ASU 2016-09 will also require an entity to elect an accounting policy to either estimate the number of forfeitures or account for forfeitures when they occur. The guidance is effective for fiscal years beginning after December 15, 2016 (January 1, 2017 for our company). We are currently evaluating the effect that the new guidance will have on our consolidated financial statements.
Leases	Leases In February 2016, the FASB issued ASU No. 2016-02, “Leases” that requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. The new standard must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. The guidance is effective for fiscal years beginning after December 15, 2018 (January 1, 2019 for our company). Early adoption is permitted. We are currently evaluating the transition method that will be elected and the effect that the new guidance will have on our consolidated financial statements.
Financial Assets and Financial Liabilities	Financial Assets and Financial Liabilities In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” that will change the income statement impact of equity investments held by an entity, and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The guidance is effective for fiscal years beginning after December 15, 2017 (January 1, 2018 for our company). We are currently evaluating the effect that the new guidance will have on our consolidated financial statements.
Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share	Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share In May 2015, the FASB issued ASU No. 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)” (“ASU 2015-07”). The guidance removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The guidance also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The guidance is effective for fiscal years beginning after December 15, 2015 (January 1, 2016 for our company). See Note 4 – Fair Value Measurements.
Interest - Imputation of Interest	Interest - Imputation of Interest In April 2015, the FASB issued ASU No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-03”). The guidance in ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The guidance is effective for fiscal years beginning after December 15, 2015 (January 1, 2016 for our company) and is required to be applied retrospectively to all periods presented beginning in the year of adoption. Upon the adoption of ASU 2015-03 by our company on January 1, 2016, the impact was a reduction in both other assets and senior notes of $9.6 million. In accordance with ASU No. 2015-03, previously reported amounts have been conformed to the current presentation, as reflected in the consolidated statements of financial condition. The impact as of December 31, 2015 was a reduction to both total assets and total liabilities of $9.9 million.
Revenue Recognition	Revenue Recognition In April 2016, the FASB issued ASU No. 2016-10, “Identifying Performance Obligations and Licensing” that amends the revenue guidance in ASU 2014-09 on identifying performance obligations. The effective date of the new guidance will coincide with ASU 2014-09 during the first quarter 2018. We are currently evaluating the effect that the new guidance will have on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” (“ASU 2016-08”) that amends the principal versus agent guidance in ASU 2014-09. ASU 2016-08 clarifies that the analysis must focus on whether the entity has control of the goods or services before they are transferred to the customer. ASU 2016-08 also provides additional guidance about how to apply the control principle when services are provided and when goods or services are combined with other goods or services. The effective date of the standard for the Company will coincide with ASU 2014-09 during the first quarter 2018. We are currently evaluating the effect that the new guidance will have on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," ("ASU 2014-09") that supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09 requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also requires additional disclosures regarding the nature, amount, timing and uncertainty of revenue that is recognized. The FASB has approved a one year deferral of this standard, and this pronouncement is now effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and is to be applied using one of two retrospective application methods, with early application not permitted. We are currently evaluating the impact the new guidance will have on our consolidated financial statements.
