Important Notice About Information Presented in this
Free Writing Prospectus

The securities described in this free writing prospectus may not be appropriate for all investors. Potential investors must be willing to assume, among other things, market price volatility, prepayment, yield curve and interest rate risks. Investors should carefully consider the risks of these securities.

We do not intend that there be any sale of the securities discussed in this free writing prospectus in any state in which such offer or sale would be unlawful prior to registration or qualification of such securities under the securities laws of any such state.

The issuer has filed a registration statement (including a prospectus) on Form S-3 with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may obtain these documents for free by visiting EDGAR on the SEC web site at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in this offering will arrange to send you the prospectus if you so request by calling toll-free 1-800-667-9569.

We will provide information to you about the offered certificates in two separate documents that progressively provide more detail: (a) a prospectus, which provides general information, some of which may not apply to your series of certificates, and (b) a form of prospectus supplement which, along with this free writing prospectus, describes more specifically the terms of your series of certificates. This free writing prospectus does not contain all of the information that is required to be included in the prospectus and the prospectus supplement that will be prepared for your series of certificates. The information in this free writing prospectus is preliminary and is subject to completion or change. The information in this free writing prospectus supersedes information contained in any prior free writing prospectus relating to these securities prior to the time of your commitment to purchase. To understand the terms of the offered certificates, read carefully this entire free writing prospectus and the prospectus and the form of prospectus supplement we will provide you. You may obtain a copy of the prospectus by contacting WaMu Capital Corp. at 1-800-667-9569.

THE DATA DESCRIBING THE MORTGAGE POOL IN THIS FREE WRITING PROSPECTUS  REFLECTS THE CHARACTERISTICS OF THE MORTGAGE POOL AS OF 06/01/07. THE PROSPECTUS SUPPLEMENT THAT WILL BE PREPARED FOR THIS TRANSACTION WILL REFLECT THE FINAL MORTGAGE POOL DATA AS OF THE CUT-OFF DATE, WHICH IS 06/01/07. ONCE AVAILABLE, A FINAL PROSPECTUS AND PROSPECTUS SUPPLEMENT MAY BE OBTAINED WITHOUT CHARGE BY CONTACTING WAMU CAPITAL CORP. AT 1-800-667-9569.

This free writing prospectus is being delivered to you solely to provide you with information about the offering of the mortgage-backed securities referred to in this free writing prospectus. The mortgage-backed securities referred to in this free writing prospectus are being offered when, as and if issued. Our obligation to sell securities to you is conditioned on the securities having the characteristics described in this free writing prospectus. If that condition is not satisfied, we will notify you, and neither the issuer nor any underwriter will have any obligation to you to deliver all or any portion of the securities which you have committed to purchase, and there will be no liability between us as a consequence of the non-delivery.



 

 

Washington Mutual Mortgage Pass-Through Certificates, WMALT Series 2007-5

Trust

Structure

 

The Washington Mutual Mortgage Pass-Through Certificates, WMALT Series 2007-5 Trust will issue securities related to one or more loan groups, each of which will have one or more related classes of senior certificates and one or more classes of subordinate certificates.  Certain classes may receive payment from interest only bonds.  If there are multiple loan groups included in the final structure, the loan groups may or may not be completely or partially cross-collateralized.  With respect to any LIBOR Certificate under consideration, a yield maintenance agreement (“YMA”) may be purchased from an approved counterparty.  A YMA, dependent upon LIBOR certificates, is intended to partially mitigate the risk of LIBOR exceeding a predetermined value, in which case the mortgage loans will not generate enough interest to pay the full certificate interest rate on the related LIBOR certificate.  The YMA counterparty will be obligated to make payments under the YMA to the Trust based on an agreed upon formula.  A preliminary structure based on the above collateral groups is described here:
