This publication has not been subject to audit.

The United States Securities and Exchange Commission (SEC) permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. We use certain terms in this publication that SEC’s guidelines strictly prohibit us from including in filings with the SE C. U.S. Investors are urged to consider closely the disclosure in our Form 20-F, File No 001-32575, available on the SEC website www.sec.gov. You can also obtain these forms from the SE C by calling 1-800-SEC-0330.

The companies in which Royal Dutch Shell plc directly and indirectly owns investments are separate entities. In this publication “Shell” and “Royal Dutch Shell” are sometimes used for convenience where references are made to Royal Dutch Shell and its subsidiaries in general. Likewise, the words “we”, “us” and “our” are also used to refer to subsidiaries in general or to those who work for them. These expressions are also used where no useful purpose is served by identifying the particular company or companies. “Subsidiaries”, “Shell subsidiaries” and “Shell companies” as used in this Report refer to companies over which Royal Dutch Shell, either directly or indirectly, has control through a majority of the voting rights or the right to exercise control or to obtain the majority of the benefits and be exposed to the majority of the risks. The Consolidated Financial Statements consolidate the financial statements of the Parent Company and all subsidiaries. The companies in which Shell has significant influence but not control are referred to as “associated companies” or “associates” and companies in which Shell has joint control are referred to as “jointly controlled entities”. Joint ventures are comprised of jointly controlled entities and jointly controlled assets. In this publication, associates and jointly controlled entities are also referred to as “equity-accounted investments”.

The term “Shell interest” is used for convenience to indicate the direct and/or indirect (for example, through our 34% shareholding in Woodside Petroleum Ltd.) ownership interest held by Shell in a venture, partnership or company, after exclusion of all third-party interests.

The term “reserves” in this publication means SEC proved oil and gas reserves and SEC proven mining reserves.

The term “resources” in this publication includes quantities of oil and gas not yet classified as SEC proved oil and gas reserves or SEC proven mining reserves. Resources are consistent with the Society of Petroleum Engineers 2P and 2C definitions and includes Oil Sands.

The Financial Statements contained in this publication have been prepared in accordance with the provisions of the Companies Act 1985, Article 4 of the International Accounting Standards (IAS) Regulation and with both International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and IFRS as adopted by the European Union. IFRS as defined above includes International Financial Reporting Interpretations Committee (IFRIC) interpretations.

To facilitate a better understanding of underlying business performance, the financial results are also presented on an estimated current cost of supplies (CCS) basis as applied for the Oil Products and Chemicals segment earnings. Earnings on an estimated current cost of supplies basis provides useful information concerning the effect of changes in the cost of supplies on Royal Dutch Shell’s results of operations and is a measure to manage the performance of the Oil Products and Chemicals segments but is not a measure of financial performance under IFRS.

Except as otherwise noted, the figures shown in this Report are stated in US dollars. As used herein all references to “dollars” or “$” are to the US currency.

Internal segment reporting is on a global basis. For the main segments an analysis of certain data is provided in this publication between the USA and the world outside the USA.

Assets and liabilities of non-US dollar subsidiaries are translated to US dollars at year-end rates of exchange, whilst their statements of income and cash flows are translated at quarterly average rates. Translation differences arising on consolidation are taken directly to a currency translation differences account within equity. Upon divestment or liquidation of an entity, cumulative currency translation differences related to that entity are taken to income.
