Since 1st January 1999, a number of changes have been made to the Group's reporting structure. Major changes, for which comparative figures have been restated as appropriate, are: Retail Financial Services has re-organised the management of its business around customer segments to deliver services and products. For reporting purposes it is organised into Retail Customers, Wealth Management and Barclaycard. Retail Customers and Wealth Management have absorbed the relevant customer segments from the previous business groupings of UK Retail Banking, International Premier, Private, Savings and Investment and Africa and Caribbean, with Barclaycard remaining unaffected. Retail Customers comprises UK Retail Banking (excluding UK Premier), the African business, UK retail mutual funds and Barclays Life. Wealth Management comprises the former International Premier, Private, Savings and Investment business (excluding UK retail mutual funds and Barclays Life), UK Premier and the Caribbean business. The Structured Export Finance business and a number of large corporate assets have been transferred from Barclays Capital to Corporate Banking. Certain internal charges have been re-allocated between Retail Financial Services and Corporate Banking. In addition, Retail Financial Services has revised its presentation of income and costs within its profit and loss account. There is no effect on total Group revenue or costs as a result of these changes. Management of central information technology and operations' services for Retail Financial Services, Corporate Banking and Group central functions in the UK has been transferred to Retail Financial Services in the year. Prior periods have been restated accordingly. Certain support services, including the Brand programme, previously reported in Head office functions are now included in Central services.
