            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 Disciplined Equity Fund,
RiverSource Large Cap Equity Fund and RiverSource Large Cap Value Fund of
RiverSource Large Cap Series, Inc. (the Funds) complied with the provisions of
subsection (b) and (c) of Rule 17f-2 under the Investment Company Act of 1940
as of July 31, 2006 and during the period from May 31, 2006 (the date of our
last examination) through July 31, 2006. Management is responsible for the
Funds' compliance with those provisions. Our responsibility is to express an
opinion on management's assertion about the Funds' 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 Funds' 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 July 31, 2006 and the period from May 31, 2006
through July 31, 2006, with respect to securities transactions:

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

o    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);

o    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;

o    Reconciliation of all such securities to the books and records of the
     Funds and the Custodian; and

o    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 Funds'
compliance with the specified requirements.


In our opinion, management's assertion that the Funds were in compliance with
the above mentioned provisions of Rule 17f-2 of the Investment Company Act of
1940 as of July 31, 2006 and for the period from May 31, 2006 through July 31,
2006 is fairly stated in all material respects.

This report is intended solely for the information and use of management of
the Funds 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.
