Information Relevant to This Presentation

Cautionary Note on Forward-LookingStatements: This presentation and related comments by management may include "forward-looking statements" within the meaning of the U.S. federal securities laws. Forward-looking statements are any statements other than statements of historical fact. Forward-looking statements represent our current judgement about possible future events and are often identified by words such as "aim", "anticipate," "appears," "approximately," "believe," "continue," "could," "designed," "effect," "estimate," "evaluate," "expect," "forecast," "goal," "initiative," "intend," "may," "objective," "outlook," "plan," "potential," "priorities," "project," "pursue," "seek," "should," "target," "when," "will," "would," or the negative of any of those words or similar expressions. In making these statements we rely upon assumptions and analysis based on our experience and perception of historical trends, current conditions and expected future developments, as well as other factors we consider appropriate under the circumstances. We believe these judgements are reasonable, but these statements are not guarantees of any future events or financial results, and our actual results may differ materially due to a variety of important factors, many of which are described in our Annual report on Form 10-K and our other filings with the Securities and Exchange Commission. We caution readers not to place undue reliance on forward-looking statements. Forward- Looking statements speak only as of the date they are made, and we undertake no obligation to update publicly or otherwise revise any forward-looking statements, whether as a result of new information, future events or other factors that affect the subject of these statements, except where we are expressly required to do so by law.

Non-GAAPFinancial Measures: See our most recent Annual Report on Form 10-K and our other filings with the Securities and Exchange Commission for a description of certain non-GAAP measures used in this presentation, including EBIT-adjusted,EPS-diluted-adjusted,ETR-adjusted,ROIC-adjusted and adjusted automotive free cash flow, along with a description of various uses for such measures. This presentation also includes GMF's return on tangible common equity, which is used by GMF's management and can be used by investors to measure GMF's contribution to GM's enterprise profitability and cash flow. Return on tangible common equity is calculated as GMF's net income attributable to common shareholder for the trailing four quarters divided by GMF's average tangible common equity for the same period. Our calculation of these non-GAAP measures are set forth within these reports and the Select Supplemental Financial Information section of this presentation and may not be comparable to similarly titled measures of other companies due to potential differences between companies in the method of calculation. As a result, the use of these non-GAAP measures has limitations and should not be considered superior to, in isolation from, or as a substitute for, related U.S. GAAP measures. When we present our total company EBIT-adjusted, GMF is presented on EBT-adjusted basis.

Additional Information: In this presentation and related comments by management, references to "record" or "best" performance (or similar statements) refer to General Motors Company, as established in 2009 on a continuing operations basis. In addition, certain figures included in the charts and tables in this presentation may not sum due to rounding.
