Section 7. Regulation FD

Item 7.01 Regulation FD Disclosure

CWHEQ Home Equity Loan Trust, Series 2007-S1 (the “Issuing Entity”) has the benefit of the Credit Insurance Policy (the “Policy”) which insures certain Mortgage Loans (referred to as the “Covered Loans”) against certain losses. The Issuing Entity also has the benefit of the Sponsor Loss Coverage Obligation provided by Countrywide Home Loans, Inc. (“Countrywide”). The Sponsor Loss Coverage Obligation is intended to cover Realized Losses on the Covered Loans with respect to which a claim for payment is denied by the insurer due to an exclusion in the Policy (such denied claims, “Covered Claims”), up to the Sponsor Loss Coverage Amount.

Historically it has been Countrywide’s policy not to make Loss Coverage Payments under its Sponsor Loss Coverage Obligation for Covered Claims until it had completed all of its efforts to obtain payment from the insurer, including exercising any appeal rights under the Policy with respect to denied claims. In connection with the implementation of a change in this policy to a policy of making Loss Coverage Payments upon the initial denial of claims, Countrywide included payment for Covered Claims on the April 2008 Distribution Date that related to initial claim denials received in a period prior to the related Due Period for such Distribution Date (such Covered Claims, the “Aged Claims”). The table below summarizes the amount of the Loss Coverage Payment by Countrywide on the April 2008 Distribution Date that would have been paid on that prior Distribution Date if Loss Coverage Payments relating to Aged Claims had been made upon the initial denial of claims.

April 2008 Distribution Date

Month of Distribution (if paid upon Initial Denial)	Number of Loans	Loss Coverage Payment
November 2007	3	$233,450.25

Countrywide does not expect the Loss Coverage Payments on subsequent Distribution Dates to include amounts for Aged Claims of a similar magnitude as were paid on the April 2008 Distribution Date.

The payment described in the preceding paragraph affects the timing of payments from the Sponsor Loss Coverage Obligation. In addition, upon final resolution of each Aged Claim the Sponsor Loss Coverage Obligation may be affected. In cases where the insurer agrees to pay an Aged Claim, Countrywide will be entitled to receive the amount covered by the insurer and the remaining Sponsor Loss Coverage Amount will increase by that amount. In cases where Countrywide’s appeals are unsuccessful, there will be no adjustment to the Sponsor Loss Coverage Amount.

No assurances are being provided herein that Loss Coverage Payments by Countrywide on Distribution Dates prior to the April 2008 Distribution Date did not include payments attributable to Aged Claims. In addition, there can be no assurance that additional Loss Coverage Payments will be made at any time prior to Countrywide making all efforts to obtain payment from the related insurer in respect of claims which are initially denied.

Capitalized terms used herein and not defined herein shall have the meanings set forth in the Pooling and Servicing Agreement, dated as of February 1, 2007, by and among Countrywide, CWHEQ, Inc., as depositor, Park Granada LLC, as a seller, Park Monaco Inc., as a seller, Park Sienna LLC, as a seller, Countrywide Home Loans Servicing LP, as master servicer, and The Bank of New York, as trustee.
