Schwab Acquisition of optionsXpress FAQs for Schwab Active Investor Customers

April 1, 2011

Q: Why is Schwab acquiring optionsXpress?

A: optionsXpress will bring product breadth and diversity to the extremely important Active Investor business, allowing Schwab to deepen its capabilities in this area. Specifically, optionsXpress offers sophisticated trading tools and technology for options traders as well as the ability to trade futures and forex. optionsXpress also offers extensive education on derivatives trading that will deepen Schwab’s existing educational offer.

Q: When will the acquisition be complete?

A: We are targeting Q3, 2011 for completion; however, the acquisition is subject to optionsXpress stockholder approval, regulatory approvals, and customary closing conditions.

Q: What impact will this have on me, an existing Schwab client?

A: For now, there will be no impact on Schwab or optionsXpress clients. Until the acquisition is complete, optionsXpress will continue to operate separately as an independent company. After the deal closes, we look forward to making innovative technology from optionsXpress available to Schwab clients and making Schwab’s breadth of investment products and services available to optionsXpress clients.

Q: Will commission rates be changing because of this acquisition?

A: All decisions about commissions at Schwab and optionsXpress will continue to be made by Schwab or optionsXpress, respectively, as independent companies until the transaction closes. We will provide information related to the transition as soon as possible after the transaction is completed.

Q: As a Schwab client, do I need to move over to the optionsXpress trading platforms?


A: There will be no change in the trading experience for Schwab clients before the transaction closes. After closing, we will leverage the combined strengths of optionsXpress and Schwab to deliver an outstanding trading experience to clients interested in equity, options, futures, and forex trading.

Q: I am a Schwab client and already have an account with optionsXpress. Who should I call regarding customer service issues?

A: If the issue is related to your Schwab account, you should call Schwab customer service. If the issue is related to your optionsXpress account, you should call optionsXpress customer service. Once the acquisition is complete, we will provide more information related to customer service.

Q: I just started using StreetSmart Edge™. After the acquisition is complete, will Schwab be merging this platform with the optionsXpress trading platform or retiring it and replacing it with the optionsXpress platform?

A: We will continue to develop StreetSmart Edge and encourage clients to try this new platform for their trading. After the acquisition is complete, we plan to incorporate the best of optionsXpress’s trading platform capabilities so that clients are able to get the best possible trading experience.

Q: How quickly can I expect to see some integration efforts between Schwab and optionsXpress?

A: Not until after the acquisition is complete, as Schwab and optionsXpress will remain separate, independent companies until then. Our first priority is to work on closing the acquisition deal, and we are targeting Q3 for that. However, the acquisition is subject to optionsXpress stockholder approval, regulatory approvals, and customary closing conditions.

Q: I trade on Schwab.com. How will my trading experience change?

A: It is too early to say. Until closing, the pending acquisition will have no impact on the Schwab.com trading experience. Once the acquisition is complete, we will look at the capabilities of both firms and determine how to bring the best possible trading experience to our clients.

Q: Will optionsXpress clients be allowed to participate in the Active Investor Community?

A: Until closing, Schwab and optionsXpress are still separate and independent companies, and optionsXpress clients are unable to utilize the Schwab AI Community unless they are also Schwab AI clients.


Q: I trade futures through Lind-Waldock. Will this continue or will I need to trade futures through optionsXpress?

A: Nothing is changing for Schwab clients trading futures at Lind-Waldock. Until the transaction is complete, optionsXpress and Schwab will continue to operate separately as independent companies, and there will be no impact on the trading experience of clients at either firm.

Q: How will my options trading experience improve as a result of this acquisition?

A: The combined strengths of optionsXpress and Schwab should deliver an outstanding trading experience to clients interested in equity, options, futures, and forex trading. It is premature at this time to discuss specifics.

Q: Will my Schwab options service be changing as a result of this acquisition?

A: There are no planned changes to your Schwab options service as a result of this acquisition.

Q: Should I move to optionsXpress now, since it will become part of Schwab?

A: While the acquisition is pending, the two companies will continue to operate and compete as separate and independent companies, so we do not encourage movement. The closing of the acquisition is subject to optionsXpress stockholder approval, regulatory approvals, and customary closing conditions.
