Item 2.01 Completion of Acquisition or Disposition of Assets

Description of the Certificates and the Mortgage Pool

On December 21, 2006 (the “Closing Date”), a series of certificates, entitled IndyMac Residential Mortgage-Backed Trust, Series 2006-L4 (the “Certificates”), was issued pursuant to a pooling and servicing agreement, dated as of December 1, 2006 (the “Agreement”), attached hereto as Exhibit 4.1, among IndyMac ABS, Inc. as depositor (the “Depositor”), IndyMac Bank F.S.B. (“IndyMac Bank”) as seller (the “Seller”) and as servicer (the “Servicer”) and Deutsche Bank National Trust Company as trustee (the “Trustee”). The Certificates consist of seven classes of certificates (collectively, the “Certificates”), designated as the Class A Certificates, Class IO Certificates, Class M Certificates, Class B Certificates, Class C Certificates, Class P Certificates and Class R Certificates. The Certificates evidence in the aggregate the entire beneficial ownership interest in a trust fund (the “Trust Fund”), consisting of a pool (the “Mortgage Pool”) of fixed rate and adjustable-rate residential lot mortgage loans (the “Mortgage Loans”) that were transferred to the Trust Fund on the Closing Date. The Mortgage Loans had an aggregate principal balance of $119,310,802.61 as of December 1, 2006 (the “Cut-off Date”).

The Class A Certificates, Class IO Certificates and Class M Certificates were sold by the Depositor to Lehman Brothers Inc. as representative of the underwriters (the “Underwriters”), pursuant to an Underwriting Agreement, dated December 14, 2006 (the “Underwriting Agreement”) among the Depositor, IndyMac Bank and the Underwriters. The Class B Certificates, Class C Certificates and Class P Certificates were delivered by the Depositor to the Seller as partial consideration for the Mortgage Loans constituting the pool assets. The Class R Certificates were sold to Citigroup Global Markets Realty Corp.

The Certificates have the following initial Certificate Balances and Pass-Through Rates:

Class Offered Certificates	Initial Certificate Principal Balance⁽¹⁾			Pass-Through Rate⁽²⁾
A	$	156,880,000.00			Variable
IO	$	160,000,000.00	⁽³⁾		Variable
M	$	1,120,000.00			Variable

⁽¹⁾	Approximate.

⁽²⁾	The pass-through rate on each class Certificates will be based on one-month LIBOR plus the applicable margin set forth in the Agreement, subject to the rate caps described in the Agreement.

⁽³⁾	The Class IO Certificates will be interest only certificates and will not have a class certificate balance. The initial notional balance is set forth in the table but is not included in the aggregate class certificate balance of all certificates offered.

The Certificates, other than the Class B Certificates, Class C Certificates, the Class P Certificates and the Class R Certificates, are more particularly described in the Prospectus Supplement, dated December 14, 2006 (the “Prospectus Supplement”), and the Prospectus, dated December 11, 2006, as previously filed with the Securities and Exchange Commission pursuant to Rule 424(b). The Class B Certificates, Class C Certificates, the Class P Certificates and the Class R Certificates have not been and will not be publicly offered by the Depositor.
