Assumptions Forecasted financial information is based on certain material assumptions . Such assumptions include, but are not limited to: (a) no unforeseen external events such as wars, depressions, or economic or political disruptions occur; (b) businesses continue to operate in a manner consistent with or better than prior operating performance, including achievement of planned productivity improvements including benefits of global sourcing, and in accordance with the provisions of their relevant contracts or concessions; (c) new business opportunities are available to AES in sufficient quantity to achieve its growth objectives; (d) no material disruptions or discontinuities occur in GDP, foreign exchange rates, inflation or interest rates during the forecast period; and (e) material business -specific risks as described in the Company’s SEC filings do not occur individually or cumulatively . In addition, benefits from global sourcing include avoided costs, reduction in capital project costs versus budgetary estimates, and projected savings based on assumed spend volume which may or may not actually be achieved. Also, improvement in certain KPIs such as equivalent forced outage rate and commercial availability may not improve financial performance at all facilities based on commercial terms and conditions. These benefits will not be fully reflected in the Company’s consolidated financial results. The cash held at qualified holding companies (“QHCs”) represents cash sent to subsidiaries of the Company domiciled outside of the U.S. Such subsidiaries had no contractual restrictions on their ability to send cash to AES, the Parent Company, however, cash held at qualified holding companies does not reflect the impact of any tax liabilities that may result from any such cash being repatriated to the Parent Company in the U.S. Cash at those subsidiaries was used for investment and related activities outside of the U.S. These investments included equity investments and loans to other foreign subsidiaries as well as development and general costs and expenses incurred outside the U.S. Since the cash held by these QHCs is available to the Parent, AES uses the combined measure of subsidiary distributions to Parent and QHCs as a useful measure of cash available to the Parent to meet its international liquidity needs. AES believes that unconsolidated parent company liquidity is important to the liquidity position of AES as a parent company because of the non-recourse nature of most of AES’ indebtedness.

Definitions Non-GAAP Financial Measures Adjusted earnings per share (a non-GAAP financial measure) is defined as diluted earnings per share from continuing operations excluding gains or losses of the consolidated entity due to (a) mark-to-market amounts related to derivative transactions, (b) unrealized foreign currency gains or losses, (c) significant gains or losses due to dispositions and acquisitions of business interests, (d) significant losses due to impairments, and (e) costs due to the early retirement of debt. The GAAP measure most comparable to Adjusted EPS is diluted earnings per share from continuing operations. AES believes that adjusted earnings per share better reflects the underlying business performance of the Company, and is considered in the Company's internal evaluation of financial performance. Factors in this determination include the variability due to mark-to-market gains or losses related to derivative transactions, currency gains or losses, losses due to impairments and strategic decisions to dispose or acquire business interests or retire debt which affect results in a given period or periods. Adjusted earnings per share should not be construed as an alternative to earnings per share, which is determined in accordance with GAAP. Adjusted Gross Margin (a non-GAAP financial measure) is defined as gross margin plus depreciation and amortization less general and administrative expenses. AES believes adjusted gross margin is a useful measure for evaluating and comparing the operating performance of its businesses because it includes the direct operating costs of its business including overhead related expenses and excludes potential differences caused by variations in capital structures affecting interest income and expense, tax positions, such as the impact of changes in effective tax rates and the impact of depreciation and amortization expense. Free cash flow (a non-GAAP financial measure) is defined as net cash from operating activities less maintenance capital expenditures (including environmental capital expenditures). AES believes that free cash flow is a useful measure for evaluating our financial condition because it represents the amount of cash provided by operations less maintenance capital expenditures as defined by our businesses, that may be available for investing or for repaying debt. Free cash flow should not be construed as an alternative to net cash from operating activities, which is determined in accordance with GAAP. Parent Company Liquidity (a non-GAAP financial measure) is defined as cash at the Parent Company plus availability under corporate credit facilities plus cash at qualified holding companies (“QHCs”). AES believes that unconsolidated Parent Company liquidity is important to the liquidity position of AES as a Parent Company because of the non-recourse nature of most of AES’ indebtedness. Subsidiary Liquidity (a non-GAAP financial measure) is defined as cash and cash equivalents and bank lines of credit at various subsidiaries. The AES Corporation (the “Company”) is a holding company that derives its income and cash flows from the activities of its subsidiaries, some of which are not wholly-owned by the Company. Accordingly, the Company has presented certain financial metrics which are defined as Proportional (a non-GAAP financial measure) to account for the Company’s ownership interest. Proportional metrics present the Company’s estimate of its share in the economics of the underlying metric. The Company believes that the Proportional metrics are useful to investors because they exclude the economic share in the metric presented that is held by non-AES shareholders. For example, Operating Cash Flow is a GAAP metric which presents the Company’s cash flow from operations on a consolidated basis, including operating cash flow allocable to noncontrolling interests. Proportional Operating Cash Flow removes the share of operating cash flow allocable to noncontrolling interests and therefore may act as an aid in the valuation the Company. Proportional metrics are reconciled to the nearest GAAP measure. Certain assumptions have been made to estimate our proportional financial measures. These assumptions include: (i) the Company’s economic interest has been calculated based on a blended rate for each consolidated business when such business represents multiple legal entities; (ii) the Company’s economic interest may differ from the percentage implied by the recorded net income or loss attributable to noncontrolling interests or dividends paid during a given period; (iii) the Company’s economic interest for entities accounted for using the hypothetical liquidation at book value method is 100%; (iv) individual operating performance of the Company’s equity method investments is not reflected and (v) all intercompany amounts have been excluded as applicable.

Definitions, Cont’d. Subsidiary Distributions Subsidiary Distributions should not be construed as an alternative to Net Cash Provided by Operating Activities which is determined in accordance with GAAP. Subsidiary Distributions are important to the Parent Company because the Parent Company is a holding company that does not derive any significant direct revenues from its own activities but instead relies on its subsidiaries’ business activities and the resultant distributions to fund the debt service, investment and other cash needs of the holding company . The reconciliation of difference between the Subsidiary Distributions and Net Cash Provided by Operating Activities consists of cash generated from operating activities that is retained at the subsidiaries for a variety of reasons which are both discretionary and non-discretionary in nature. These factors include, but are not limited to, retention of cash to fund capital expenditures at the subsidiary, cash retention associated with non-recourse debt covenant restrictions and related debt service requirements at the subsidiaries, retention of cash related to sufficiency of local GAAP statutory retained earnings at the subsidiaries, retention of cash for working capital needs at the subsidiaries, and other similar timing differences between when the cash is generated at the subsidiaries and when it reaches the Parent Company and related holding companies .
