The analysis in this report is based on information provided by ACE Securities Corp. (the “Depositor”). Investors are urged to read the base prospectus and the prospectus supplement and other relevant documents filed or to be filed with the Securities and Exchange Commission because they contain important information. Such documents may be obtained without charge at the Securities and Exchange Commission's website. Once available, the base prospectus and prospectus supplement may be obtained without charge by contacting Deutsche Bank Securities Inc.’s (“DBSI”) trading desk at (212) 250-7730. This free writing prospectus is not required to contain all information that is required to be included in the base prospectus and the prospectus supplement (collectively, the “Prospectus”). The information in this free writing prospectus is preliminary and is subject to completion or change. The information in this free writing prospectus, if conveyed prior to the time of your commitment to purchase, supersedes information contained in any prior similar free writing prospectus relating to these securities. This free writing prospectus is not an offer to sell or a solicitation of an offer to buy these securities in any state where such offer, solicitation or sale is not permitted. You should consult your own counsel, accountant, and other advisors as to the legal, tax, business, financial and related aspects of a purchase of these securities.
 
The attached information contains certain tables and other statistical analyses (the “Computational Materials”) which have been prepared by DBSI in reliance upon information furnished by the Depositor. Numerous assumptions were used in preparing the Computational Materials that may or may not be reflected herein. As such, no assurance can be given as to whether the Computational Materials and/or the assumptions upon which they are based reflect present market conditions or future market performance. These Computational Materials should not be construed as either projections or predictions or as legal, tax, financial or accounting advice. Any weighted average lives, yields and principal payment periods shown in the Computational Materials are based on prepayment assumptions, and changes in such prepayment assumptions may dramatically affect such weighted average lives, yields and principal payment periods. In addition, it is possible that prepayments on the underlying assets will occur at rates slower or faster than the rates shown in the attached Computational Materials. Furthermore, unless otherwise provided, the Computational Materials assume no losses on the underlying assets and no interest shortfalls. The specific characteristics of the securities may differ from those shown in the Computational Materials by a permitted variance of +/- 10% prior to issuance. Neither DBSI nor any of its affiliates makes any representation or warranty as to the actual rate or timing of payments on any of the underlying assets or the payments or yield on the securities.  
 
An investor or potential investor in the certificates (and each employee, representative, or other agent of such person or entity) may disclose to any and all persons, without limitation, the tax treatment and tax structure of the transaction (as defined in United States Treasury Regulation Section 1.6011-4) and all related materials of any kind, including opinions or other tax analyses, that are provided to such person or entity. However, such person or entity may not disclose any other information relating to this transaction unless such information is related to such tax treatment and tax structure.

Transaction Overview (Cont.)

 
Capitalized Interest Account:
On the Closing Date and if required pursuant to the pooling and servicing agreement, the depositor will deposit cash into the Capitalized Interest Account. The amount on deposit in the Capitalized Interest Account will be specifically allocated to cover shortfalls in interest on each class of Offered Certificates and the Class M-11 Certificates related to the Mortgage Loans that may arise as a result of the utilization of the Prefunding Account for the purchase by the trust of Subsequent Mortgage Loans after the Closing Date. Any amounts remaining in the Capitalized Interest Account (including investment earnings) and not needed for such purpose will be paid to the depositor and will not thereafter be available for payment to the certificateholders. Amounts on deposit in the Capitalized Interest Account will be invested in permitted investments. The Capitalized Interest Account will not be included as an asset of any REMIC pursuant to the pooling and servicing agreement.
   
Optional Termination:
On any Distribution Date on which the aggregate outstanding principal balance of the Mortgage Loans as of the last day of the related Due Period is less than or equal to 10% of the aggregate outstanding principal balance of the Mortgage Loans as of the Cut-off Date, the Master Servicer may repurchase all of the Mortgage Loans and REO properties remaining in the trust, causing an early retirement of the Certificates, but is not required to do so.
   
Monthly Servicer Advances:
The Servicer will collect monthly payments of principal and interest on the Mortgage Loans and will be obligated to make advances of delinquent monthly principal and interest payments. The Servicer is required to advance delinquent payments of principal and interest on the Mortgage Loans only to the extent such amounts are deemed recoverable. If the Servicer fails to make any such advance, the Master Servicer will be required to do so subject to its determination of recoverability. The Servicer and the Master Servicer are entitled to be reimbursed for these advances, and therefore these advances are not a form of credit enhancement.
   
Credit Enhancement:
1) Excess Interest;
 
2) Net Swap Payments received from the Swap Provider (if any);
 
3) Overcollateralization (“OC”); and
 
4) Subordination.
   
Allocation of Losses:
Any Realized Losses on the Mortgage Loans will be allocated on any Distribution Date, first, to Net Monthly Excess Cashflow and Net Swap Payments received from the Swap Provider, if any, second, to the Class CE Certificates, third, to the Class M-11 Certificates, fourth, to the Class M-10 Certificates, fifth, to the Class M-9 Certificates, sixth, to the Class M-8 Certificates, seventh, to the Class M-7 Certificates, eighth, to the Class M-6 Certificates, ninth, to the Class M-5 Certificates, tenth, to the Class M-4 Certificates, eleventh, to the Class M-3 Certificates, twelfth, to the Class M-2 Certificates, and thirteenth to the Class M-1 Certificates. There will be no allocation of Realized Losses to the Class A Certificates. Investors in the Class A Certificates should note, however, that although Realized Losses cannot be allocated to such Certificates, under certain loss scenarios there may not be enough principal and interest on the Mortgage Loans to distribute to the holders of the Class A Certificates all principal and interest amounts to which they are then entitled. 
   
 
Once Realized Losses have been allocated to the Mezzanine Certificates, such amounts with respect to such Certificates will no longer accrue interest and such amounts will not be reinstated thereafter. However, the amount of any Realized Losses allocated to the Mezzanine Certificates may be distributed to such certificates on a subordinated basis on any Distribution Date from Net Monthly Excess Cashflow, to the extent available on such Distribution Date and any Net Swap Payments paid by the Swap Provider.

Transaction Overview (Cont.)

Required Overcollateralization Amount:
Overcollateralization refers to the amount by which the aggregate principal balance of the Mortgage Loans exceeds the aggregate certificate principal balance of the Certificates. This excess (the “Overcollateralization Amount”) is intended to protect the certificateholders against shortfalls in payments on the Certificates. The Required Overcollateralization Amount for the Certificates, which will be fully established at issuance, is anticipated to be approximately 2.25% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date. On or after the Stepdown Date and provided that a trigger event is not in effect, the Required Overcollateralization Amount may be permitted to decrease to approximately 4.50% of the aggregate principal balance of the Mortgage Loans as of the last day of the related Due Period, subject to a floor amount of approximately 0.50% of the aggregate outstanding principal balance as of the Cut-off Date. If, due to losses, the Overcollateralization Amount is reduced below the Required Overcollateralization Amount, excess spread, if any is available, will be paid to the Certificates then entitled to receive distributions in respect of principal in order to reduce the certificate principal balance of such Certificates to the extent necessary to reach the Required Overcollateralization Amount. In addition, Net Swap Payments paid by the Swap Provider may be used to restore or maintain the Required Overcollateralization Amount.
   
Overcollateralization Increase Amount:
An Overcollateralization Increase Amount for any Distribution Date is the lesser of (i) the Net Monthly Excess Cashflow and Net Swap Payments received from the Swap Provider, if any, for that Distribution Date and (ii) the excess of the Required Overcollateralization Amount over the current Overcollateralization Amount.
   
Overcollateralization Reduction Amount:
An Overcollateralization Reduction Amount for any Distribution Date is the amount by which the current Overcollateralization Amount exceeds the Required Overcollateralization Amount after taking into account all other distributions to be made on the Distribution Date limited to the distribution of principal on the Mortgage Loans.
   
Stepdown Date:

Net Monthly Excess
Cashflow:
For any Distribution Date is equal to the sum of (i) any Overcollateralization Reduction Amount and (ii) the excess of the Available Distribution Amount, net of any Net Swap Payment and the Swap Termination Payment, if any, required to be made by the Securities Administrator, on behalf of the supplemental interest trust (described below), to the Swap Provider under the Swap Agreement, over the sum of (w) with respect to the Class A Certificates, the Senior Interest Distribution Amount for such Distribution Date, (x) with respect to the Mezzanine Certificates, the Interest Distribution Amount for such Distribution Date and (y) the amount of principal required to be distributed to the holders of the Certificates on such Distribution Date.
   
Net WAC Pass-
Through Rate:
Class A-1 and Class A-2 Certificates: The per annum rate (subject to adjustment based on the actual number of days elapsed in the related Interest Accrual Period) equal to the product of (i) 12 and (ii) a fraction, expressed as a percentage, the numerator of which is the sum of (a) the amount of interest which accrued on the Mortgage Loans in the related loan group in the prior calendar month minus the fees payable to the Servicer, Master Servicer and the Credit Risk Manager with respect to the related Mortgage Loans for such Distribution Date, and (b) the Group I Allocation Percentage or Group II Allocation Percentage, as applicable, of any Net Swap Payment or Swap Termination Payment made to the Swap Provider for such Distribution Date (which was not caused by a Swap Provider Trigger Event, as defined in the interest rate swap agreement), and the denominator of which is the aggregate principal balance of the Mortgage Loans in the related loan group as of the last day of the immediately preceding Due Period (or as of the Cut-off Date with respect to the first Distribution Date), after giving effect to principal prepayments received during the related Prepayment Period.
   
 
Mezzanine Certificates: The per annum rate equal to the weighted average (weighted in proportion to the results of subtracting from the aggregate principal balance of each loan group, the certificate principal balance of the related Class A Certificates), of (i) the Net WAC Pass-Through Rate for the Class A-1 Certificates and (ii) the Net WAC Pass-Through Rate for the Class A-2 Certificates.
   
 
Group I Allocation Percentage: The aggregate principal balance of the Group I Mortgage Loans divided by the sum of the aggregate principal balance of the Group I Mortgage Loans and the Group II Mortgage Loans.

Net WAC Rate
Carryover Amount:
If on any Distribution Date the Pass-Through Rate for any class of Certificates is limited by the related Net WAC Pass-Through Rate, such class will be entitled to the “Net WAC Rate Carryover Amount” which will be equal to the sum of (i) the excess of (a) the amount of interest that would have accrued on such class based on one-month LIBOR plus the related margin over (b) the amount of interest accrued on such class based on the related Net WAC Pass-Through Rate and (ii) the unpaid portion of any related Net WAC Rate Carryover Amount from the prior Distribution Date together with accrued interest on such unpaid portion at a rate equal to one-month LIBOR plus the related margin for the most recently ended Interest Accrual Period. Any Net WAC Rate Carryover Amount will be paid on such Distribution Date or future Distribution Dates to the extent of funds available. The Net WAC Rate Carryover Amount will be distributed from certain amounts received by the Securities Administrator, on behalf of the Supplemental Interest Trust (described below), under the Swap Agreement, if any, and from the Net Monthly Excess Cashflow on a subordinated basis on the same Distribution Date or on any subsequent Distribution Date to the extent of available funds. The ratings on each class of Certificates do not address the likelihood of the payment of any Net WAC Rate Carryover Amount from Net Monthly Excess Cashflow.

Swap Agreement:
On the Closing Date, the Trustee will enter into a Swap Agreement with the Swap Provider as described in the final prospectus supplement. The Swap Agreement will have an initial notional amount of $615,730,544. Under the Swap Agreement, commencing on the Distribution Date occurring in April 2007, the trust (through a supplemental interest trust) will be obligated to pay an amount equal to [5.07]% per annum on the notional amount as set forth in the Swap Agreement to the Swap Provider and the Swap Provider will be obligated to pay to the supplemental interest trust, for the benefit of the holders of the Offered Certificates and the Class M-11 Certificates, an amount equal to one-month LIBOR on the notional amount as set forth in the Swap Agreement until the Swap Agreement is terminated. Only the net amount of the two obligations will be paid by the appropriate party (the “Net Swap Payment”). See the attached schedule.
   
 
A separate trust created under the pooling and servicing agreement (the “Supplemental Interest Trust”) will hold the Swap Agreement. The Swap Agreement and any payments made by the Swap Provider thereunder will be assets of the Supplemental Interest Trust but will not be assets of any REMIC.
   
 
Upon early termination of the Swap Agreement, the Supplemental Interest Trust or the Swap Provider may be liable to make a termination payment (the ‘‘Swap Termination Payment’’) to the other party (regardless of which party caused the termination). The Swap Termination Payment will be computed in accordance with the procedures set forth in the Swap Agreement. In the event that the Securities Administrator, on behalf of the Supplemental Interest Trust, is required to make a Swap Termination Payment, that payment will be paid on the related Distribution Date, and on any subsequent Distribution Dates until paid in full, and, if such Swap Termination Payment is not due as a result of the occurrence of a Swap Provider Trigger Event (as defined in the Swap Agreement), such payment will be prior to distributions to Certificateholders.
   
Available Distribution
Amount:
For any Distribution Date, net of the administrative fees, an amount equal to (i) the aggregate amount of scheduled monthly payments on the Mortgage Loans due on the related Due Date and received on or prior to the related Determination Date; (ii) unscheduled payments in respect of the Mortgage Loans (including prepayments, insurance proceeds, liquidation proceeds, subsequent recoveries and proceeds from repurchases of and substitutions for the Mortgage Loans occurring during the Prepayment Period or proceeds from the repurchase of the Mortgage Loans due to the Optional Termination of the Trust); (iii) all P&I Advances with respect to the Mortgage Loans received for the Distribution Date; and (iv) all Compensating Interest paid by the Servicer or the Master Servicer in respect of Prepayment Interest Shortfalls for the related Prepayment Period.

Class A Principal
Distribution Amount:
The Class A Principal Distribution Amount will be distributed to the holders of the Class A-1 Certificates and the Class A-2 Certificates concurrently, on a pro rata basis based on the related Class A principal allocation percentage (for any Distribution Date, the percentage equivalent of a fraction, the numerator of which is the principal remittance amount for the Group I Mortgage Loans (in the case of the Class A-1 Certificates) or the principal remittance amount for the Group II Mortgage Loans (in the case of the Class A-2 Certificates) and the denominator of which is equal to the principal remittance amount for all of the Mortgage Loans).
   
 
Until the Stepdown Date, or if a Trigger Event occurs, the Class A Certificates will receive the principal collected on the Mortgage Loans plus any excess interest and any net swap payment received required to maintain the Required Overcollateralization Amount until the aggregate certificate principal balance of the Class A Certificates has been reduced to zero. On or after the Stepdown Date, if no Trigger Event occurs, principal paid on the Class A Certificates will be an amount such that the Class A Certificates will maintain approximately a 46.60% Credit Enhancement Percentage (2x the Class A Initial Credit Enhancement Percentage). The Class A Principal Distribution Amount will be distributed to the holders of the Class A-1 Certificates and the Class A-2 Certificates to the extent of their respective group-based principal distribution amount.
   
 
Principal distributions to the Class A-2 Certificates will be allocated sequentially to the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates, in that order, until the certificate principal balance of each such class has been reduced to zero; provided, however, on any Distribution Date on which the aggregate certificate principal balance of the Mezzanine Certificates has been reduced to zero, all principal distributions will be distributed to the Class A-2 Certificates concurrently, on a pro rata basis, based on the certificate principal balance of each such class, until the certificate principal balance of each such class has been reduced to zero.
   
Class M Principal
Distribution Amount:
Unless the Class A certificate principal balance is reduced to zero, the Mezzanine Certificates will not receive any principal payments until the Stepdown Date.
