             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of
RiverSource Large Cap Series, Inc.:

We have examined management's assertion, included in the accompanying Management
Statement Regarding Compliance with Certain Provisions of the Investment Company
Act of 1940, that RiverSource Growth Fund of RiverSource Large Cap Series, Inc.
(the Fund) complied with the provisions of subsection (b) and (c) of Rule 17f-2
under the Investment Company Act of 1940 as of April 30, 2007 and during the
period from September 30, 2006 (the date of our last examination) through April
30, 2007. Management is responsible for the Fund's compliance with those
provisions. Our responsibility is to express an opinion on management's
assertion about the Fund's compliance based on our examination.

Our examination was made in accordance with standards established by the Public
Company Accounting Oversight Board (United States) and, accordingly, included
examining, on a test basis, evidence about the Fund's compliance with those
requirements and performing such other procedures as we considered necessary in
the circumstances. Included among our procedures were the following tests
performed as of April 30, 2007 and the period from September 30, 2006 through
April 30, 2007, with respect to securities transactions:

- -    Count and inspection of all securities located in the vault, if any, of
     Ameriprise Trust Company, the Custodian, without prior notice to
     management;

- -    Confirmation of all securities, if any, held by institutions in book entry
     form (Wells Fargo Bank Minnesota, N.A., The Bank of New York, and The
     Depository Trust Company);

- -    Confirmation or examination of underlying documentation of all securities
     purchased but not received, hypothecated, pledged, placed in escrow, or out
     for transfer with brokers, pledges and/or transfer agents;

- -    Reconciliation of all such securities to the books and records of the Fund
     and the Custodian; and

- -    Test of selected security transactions since the date of our last report.

We believe that our examination provides a reasonable basis for our opinion. Our
examination does not provide a legal determination on the Fund's compliance with
the specified requirements.




In our opinion, management's assertion that the Fund was in compliance with the
above mentioned provisions of Rule 17f-2 of the Investment Company Act of 1940
as of April 30, 2007 and for the period from September 30, 2006 through April
30, 2007 is fairly stated in all material respects.

This report is intended solely for the information and use of management of the
Fund and the Securities and Exchange Commission and should not be used for any
other purpose and is not intended to be and should not be used by anyone other
than these specified parties.
