Ameritrade Holding Corporation (Nasdaq:AMTD) and Starwood Hotels & Resorts Worldwide, Inc. (NYSE:HOT) announced a marketing partnership designed to promote Ameritrade to Starwood Preferred Guest(R) members and to reward existing Ameritrade clients with Starpoint offers. Starting today, Starwood Preferred Guests can earn up to 20,000 Starpoints when opening a new individual or joint Ameritrade(R) account. For more details, visit www.ameritrade.com/spg/. Starting later this year, all Ameritrade clients will have the opportunity to stock up on Starpoints when adding funds to existing accounts.

"This powerful marketing partnership offers even more compelling reasons for self-directed investors to choose Ameritrade," said Anne Nelson, Ameritrade's chief marketing officer. "By strategically aligning ourselves with the Starwood Preferred Guest program, we can now provide a special opportunity to help our clients achieve both their travel and financial goals."
