Summary of Accounting Policies	Summary of Accounting Policies The Condensed Consolidated Financial Statements of DST Systems, Inc. (“DST” or the “Company”) included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to enable a reasonable understanding of the information presented. These Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the consolidated financial position and the results of operations, comprehensive income and cash flows for the periods presented. Certain amounts in the 2013 financial statements have been reclassified to conform to the 2014 presentation. The results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the full year 2014. New authoritative accounting guidance In July 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists.” This standard requires netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. This standard is effective prospectively for annual and interim periods beginning after December 15, 2013. The adoption of this guidance did not have a significant effect on the consolidated financial statements. In May 2014, the FASB issued an accounting standard, “Revenue from Contracts with Customers.” This standard will replace the existing accounting standard for revenue recognition and is effective for annual and interim periods beginning after December 15, 2016. Early application of this standard is not permitted. This standard permits two transition approaches, either the retrospective transition method or the cumulative effect transition method. The Company is currently evaluating the standard, including which transition approach will be applied and the estimated impact it will have on the consolidated financial statements.
