Safe Harbor Certain statements contained herein may constitute “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements are typically identified by words such as “believe,” “expect,” “anticipate,” “intend,” “target,” “estimate,” “continue,” “positions,” “prospects” or “potential,” by future conditional verbs such as “will,” “would,” “should,” “could” or “may,” or by variations of such words or by similar expressions. These “forward-looking statements” are not historical facts and are based on current expectations, estimates and projections about KCG's industry, management's beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Any forward-looking statement contained herein speaks only as of the date on which it is made. Accordingly, readers are cautioned that any such forward-looking statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict including, without limitation, risks associated with: (i) the strategic business combination (the “Mergers”) of Knight Capital Group, Inc. (“Knight”) and GETCO Holding Company, LLC (“GETCO”); (ii) difficulties and delays in fully realizing cost savings and other benefits of the Mergers and the inability to manage trading strategy performance and sustain revenue and earnings growth; (iii) the sale of KCG Hotspot; (iv) changes in market structure, legislative, regulatory or financial reporting rules, including the increased focus by Congress, federal and state regulators, the SRO’s and the media on market structure issues, and in particular, the scrutiny of high frequency trading, alternative trading systems, market fragmentation, colocation, access to market data feeds, and remuneration arrangements such as payment for order flow and exchange fee structures; (v) past or future changes to KCG's organizational structure and management; (vi) KCG's ability to develop competitive new products and services in a timely manner and the acceptance of such products and services by KCG's customers and potential customers; (vii) KCG's ability to keep up with technological changes; (viii) KCG's ability to effectively identify and manage market risk, operational and technology risk (such as the events that affected Knight on August 1, 2012), legal risk, liquidity risk, reputational risk, counterparty and credit risk, international risk, regulatory risk, and compliance risk; (ix) the cost and other effects of material contingencies, including litigation contingencies, and any adverse judicial, administrative or arbitral rulings or proceedings; (x) the effects of increased competition and KCG's ability to maintain and expand market share; and (xi) the announced plan to relocate KCG’s global headquarters from Jersey City, NJ to New York, NY. The list above is not exhaustive. Because forward looking statements involve risks and uncertainties, the actual results and performance of KCG may materially differ from the results expressed or implied by such statements. Given these uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. Unless otherwise required by law, KCG also disclaims any obligation to update its view of any such risks or uncertainties or to announce publicly the result of any revisions to the forward-looking statements made herein. Readers should carefully review the risks and uncertainties disclosed in KCG’s reports with the U.S. Securities and Exchange Commission (“SEC”), including those detailed under “Certain Factors Affecting Results of Operations” in the MD&A and in “Risk Factors” in Part I, Item 1A of KCG 's Annual Report on Form 10-K for the year ended December 31, 2014, and in Part II, Item 1A of the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2015, and in other reports or documents KCG files with, or furnishes to, the SEC from time to time.
