IndyMac Bancorp, Inc. (NYSE: NDE) is the holding company for IndyMac Bank®, the largest savings and loan or bank headquartered in Los Angeles County and the 14th largest thrift nationwide (based on assets). Founded in 1985, IndyMac® is in the business of designing, manufacturing, and distributing cost-efficient financing for the acquisition, development, and improvement of single-family homes. IndyMac also provides financing secured by single- family homes to facilitate consumers’ personal financial goals and strategically invests in single-family mortgage related assets. We facilitate the acquisition, development, and improvement of single-family homes through our award-winning e-MITS® (Electronic Mortgage Information and Transaction System) platform that automates underwriting, risk-based pricing and ratelocking on a nationwide basis via the Internet at the point of sale. IndyMac Bank offers highly competitive mortgage products and services that are tailored to meet the needs of both consumers and business professionals.

IndyMac is structured to achieve synergies among its operations and to enhance customer service. Operating through its three main segments, IndyMac Mortgage Bank, IndyMac Consumer Bank and the Investment Portfolio Group, the common denominator of the Company’s business is providing consumers with single-family residential mortgages through relationships with each segment’s core customers via the channels in which each operates.

IndyMac Mortgage Bank is focused on providing consumer mortgage products through relationships with mortgage and real estate professionals. The Mortgage Bank also provides commercial loans to homebuilders for the purpose of constructing new, single- family residences.

IndyMac Consumer Bank provides the platform for the mortgage and FDIC-insured deposit products and services that IndyMac offers directly to consumers.

The Investment Portfolio Group serves as the main link to customers whose mortgages we service. Through its investments in single-family residential mortgages, mortgage-backed securities and the servicing of over $37 billion of single-family mortgage loans, the Investment Portfolio Group generates core spread and fee income and provides critical support to IndyMac’s mortgage lending operations.

IndyMac’s management is committed to delivering superior returns and shareholder value. IndyMac’s total annualized return to shareholders for the period December 31, 1992 through December 31, 2003 of 24%, under its current management team, has exceeded the comparable returns of 13% and 11% for the Dow Jones Industrial Average and S&P 500, respectively, for the same period.
