Barclays RI Notes FOR INFORMATION ONLY To transact, please contact your broker or investment advisor 02 September 2010 14:33:56 Product Overview Product Type Product Listings New Issues Secondary Mkts Educational Product Primers Contacts Website Overview Welcome to the Barclays Retirement Income Notes™ informational website. Two major societal trends are currently converging: pension schemes have been shifting from “defined benefit” plans to “defined contribution” arrangements, (such as 401k plans,) where individuals take responsibility for growing their own retirement investments, and a huge demographic group known as the “Baby Boomers” is beginning to enter retirement. Once people reach retirement after having grown the value of their defined-contribution assets, they are faced with the problem of how to convert that lump-sum value into a stream of payments that will cover their ongoing expenses during retirement. Since suitable options to manage cash flows may be limited, investors are looking for innovative ideas and creative solutions to mitigate risk, generate income, and maintain control over their investments. The BARCLAYS RETIREMENT INCOME NOTES™ suite of products seeks to provide a cost-efficient, transparent, and flexible alternative for generating retirement income. These products are securities that may be bought, sold, or transferred, and each security is constructed to pay a minimum monthly nominal or inflation-adjusted cash amount, which includes a monthly return of principal spread over time. In addition to those seeking to generate retirement income, these notes may be equally useful to anyone seeking to generate a smoothed cash-flow profile of payments that include a monthly return of principal spread over time. There are currently two types of Barclays Retirement Income Notes™: Level-Pay Notes and Inflation-Indexed Level-Pay Notes. Product Primers offer summary explanations of how these notes work. New Issues offer an overview of Barclays Retirement Income Notes™ that may be issued in the near future and become available for sale. Secondary Mkts give summary indications of the remaining value for which previously issued Barclays Retirement Income Notes™ may be sold. A summary listing of both new-issue and previously issued RI Notes™ can be seen in Product Overview on the Homepage. Please use the drop-down filter. By clicking on the summary line for an individual note, you can drill down to see complete details, including the freewriting prospectus and prospectus supplement filed with the SEC. If you are interested in buying or selling a Barclays Retirement Income Note™, please speak to your broker or investment advisor. Inflation-Indexed Level-Pay Notes Barclays Inflation-Indexed Level-Pay Notes (IILP Notes) are securities that provide inflation-adjusted monthly payments for a fixed period. Unlike a standard bond that pays periodic interest and returns 100% of principal at maturity, Inflation-Indexed Level-Pay Notes distribute monthly payments that consist of both inflation-adjusted interest and a partial return of inflation-adjusted principal. IILP Notes may be used as an effective cash flow management tool and as part of an investment or retirement portfolio. Our Firm Accessibility Privacy Policy © Barclays Bank PLC 2010
