               Equity Loan Pass-Through Certificates, Series 1999-LB1.
               File No. 333-56213-01.

          Ladies and Gentlemen:

          Enclosed herewith for filing on behalf of the trust fund (the
          "Trust") created pursuant to a Pooling and Servicing Agreement
          dated as of  June 1, 1999 (the "Pooling and Servicing
          Agreement") among Ace Securities Corp., a Delaware corporation, in
          its capacity as depositor (the "Depositor"), Long Beach Mortgage
          Company, a Delaware corporation, in its capacity as servicer (the
          "Servicer"), and the Bank of New York, a New York banking
          corporation, in its capacity as trustee (the "Trustee"), is a
          Current Report on Form 8-K (the "Report").

          The Home Equity Loan Pass-Through Certificates will consist of the
          following classes:  Class A1, Class A2, Class B and Class R
          (together, the "Certificates").

          The Class A1 and A2 Certificates are referred to herein as the
          "Senior Certificates."  Only the Class A1, Class A2 and Class B
          Certificates (the "Offered Certificates") are offered hereby.  The
          Class A1, Class A2 and Class B Certificates are referred to herein as
          the "LIBOR Certificates."  The Class B and Class R Certificates are
          referred to herein as the "Subordinate Certificates."  The Class R
          Certificate is also referred to as the "Residual Certificate."

          The Class R Certificate will be issued as a single Certificate in
          fully registered, certificate form.

          The Certificates represent beneficial ownership interests in a trust
          fund (the "Trust Fund"), the assets of which consist primarily of (1)
          two pools ("Pool 1" and "Pool 2," respectively, and each, a "Mortgage
          Pool") of conventional, adjustable and fixed rate, fully amortizing
          and balloon, first lien residential mortgage loans (the "Mortgage
          Loans"), (2) the assets that from time to time are identified as
          deposited in respect of the Mortgage Loans in the Collection Account
          and the Certificate Account, (3) property acquired by foreclosure of
          Mortgage Loans or deed in lieu of foreclosure, (4) the MBIA Insurance
          Policy, (5) any other applicable insurance policies and all proceeds
          thereof, (6) the Cap Agreement, and (7) the Reserve Fund.

          The Offered Certificates were registered under the Securities Act of
          1933, as amended, by a Registration Statement on Form S-11 (File No.
          333-56213-01).  As a result, the Trust is subject to the filing
          requirements of Section 15(d) of the Securities Exchange Act of 1934,
          as amended (the "Exchange Act").  The Trust intends to fulfill these
          filing requirements in the manner described herein:

          The Trust will file, within 15 business days after each Distribution
          Date (as defined in the Pooling and Servicing Agreement), a Current
          Report on Form 8-K in substantially the form attached herewith,
          including as an exhibit thereto the applicable Distribution Date
          report.  Each such Current Report will also disclose under Item 5 any
          matter occurring during the relevant reporting period which would be
          reportable under Item 1, 2, 4 or 5 of Part II of Form 10-Q.

          The Trust will file a Current Report on Form 8-K promptly after the
          occurrence of any event described under Item 2, 3, 4 or 5 thereof,
          responding to the requirements of the applicable Item.

          Within 90 days after the end of each fiscal year, the Trust will file
          an annual report of Form 10-K which responds to Items 2, 3, and 4 of
          Part I, Items 5 and 9 of Part II, Items 12 and 13 of Part III and
          Item 14 of Part IV thereof, and include as exhibits thereto certain
          information from the Distribution Date reports aggregated for such
          year and a copy of the independent accountants' annual compliance
          statement required under the Pooling and Servicing Agreement.

          The Trust will follow the above procedures except for any fiscal year
          as to which its reporting obligations under Section 15(d) of the
          Exchange Act have been suspended pursuant to such Section.  In such
          event, the Trust will file a Form 15 as required under Rule 15d-6.

          Should you wish to discuss the above filing procedures, please call
          Judy L. Gomez at (714) 253-7562.
