Description of Business and Significant Accounting Policies	1.Description of Business and Significant Accounting Policies Waddell & Reed Financial, Inc. and Subsidiaries Waddell & Reed Financial, Inc. (hereinafter referred to as the “Company,” “we,” “our” or “us”) is a holding company, incorporated in the state of Delaware in 1981, that conducts business through its subsidiaries. Founded in 1937, we are one of the oldest mutual fund complexes in the United States, having introduced the Waddell & Reed Advisors group of mutual funds (the “Advisors Funds”) in 1940. Over time, we added additional mutual funds: Ivy Funds (the “Ivy Funds”); Ivy Variable Insurance Portfolios, our variable product offering (“Ivy VIP”); InvestEd Portfolios, our 529 college savings plan (“InvestEd”); Ivy High Income Opportunities Fund, a closed-end mutual fund (“IVH”); and the Ivy Global Investors Société d’Investissement à Capital Variable (the “SICAV”) and its Ivy Global Investors sub‑funds (the “IGI Funds”), an undertaking for the collective investment in transferable securities (“UCITS”). In 2016, we introduced the Ivy NextShares® exchange-traded managed funds (“Ivy NextShares”). In April of 2017, we launched index funds in partnership with ProShares® Advisors LLC (“Ivy ProShares”) (collectively, the Advisors Funds, Ivy Funds, Ivy VIP, InvestEd, IVH, Ivy NextShares and Ivy ProShares are referred to as the “Funds”). As of June 30, 2017, we had $80.4 billion in assets under management. We derive our revenues from providing investment management, investment advisory, investment product underwriting and distribution, and shareholder services administration to the Funds, the IGI Funds, and institutional and separately managed accounts. Investment management fees are based on the amount of average assets under management and are affected by sales levels, financial market conditions, redemptions and the composition of assets. Our underwriting and distribution revenues consist of fees earned on fee‑based asset allocation products and related advisory services, asset‑based service and distribution fees promulgated under Rule 12b-1 of the Investment Company Act of 1940, as amended (“Rule 12b-1”), commissions derived from sales of investment and insurance products, and distribution fees on certain variable products. The products sold have various commission structures and the revenues received from those sales vary based on the type and dollar amount sold. Shareholder service fee revenue includes transfer agency fees, custodian fees from retirement plan accounts, and portfolio accounting and administration fees, and is earned based on assets under management or number of client accounts. Basis of Presentation We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although we believe that the disclosures are adequate to enable a reasonable understanding of the information presented. The information in this Quarterly Report on Form 10-Q should be read in conjunction with Part I, Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016 (the “2016 Form 10-K”). Certain amounts in the prior year’s financial statements have been reclassified for consistent presentation. The accompanying unaudited consolidated financial statements are prepared consistent with the accounting policies described in Note 1 to the consolidated financial statements included in our 2016 Form 10-K with the exception of the adoption of Accounting Standards Update (“ASU”) 2016-09, “Improvements to Employee Share-Based Payment Accounting,” effective January 1, 2017. As required by this ASU, excess tax benefits and tax shortfalls resulting from share-based compensation are recognized as income tax benefit or expense in the income statement on a prospective basis. Additionally, excess tax benefits or shortfalls recognized on share-based compensation are classified as an operating activity in the statement of cash flows. The Company has applied this provision prospectively, and thus, the prior period presented in the statement of cash flows has not been adjusted. This ASU allows entities to withhold shares issued during the settlement of a stock award or option, as a means of meeting minimum tax withholding due by the employee, in an amount up to the employees’ maximum individual tax rate in the relevant jurisdiction without resulting in a liability classification of the award. The value of the withheld shares is then remitted by the Company in cash to the taxing authorities on the employees’ behalf. The Company’s historical policy to withhold shares equivalent to the minimum individual tax rate is consistent with the thresholds meeting the classification of an equity award and, therefore, a retrospective classification adjustment was not required. This ASU requires that all cash payments made to taxing authorities on the employees’ behalf for withheld shares be presented as financing activities on the statement of cash flows. As this requirement is consistent with the Company’s historical accounting policy, a retrospective adjustment to presentation of the statement of cash flows was not required. This standard also allows for the option to account for forfeitures as they occur when determining the amount of share-based compensation expense to be recognized, rather than estimating expected forfeitures over the course of a vesting period. The Company elected to account for forfeitures as they occur. The net cumulative effect to the Company from the adoption of this ASU was an increase to additional paid-in capital of $3.5 million, a reduction to retained earnings of $2.2 million and an increase to the non-current deferred tax asset of $1.3 million as of January 1, 2017. In our opinion, the accompanying unaudited consolidated financial statements reflect all adjustments (consisting of only a normal and recurring nature) necessary to present fairly our financial position at June 30, 2017, and the results of operations and cash flows for the six months ended June 30, 2017 and 2016 in conformity with accounting principles generally accepted in the United States.
