                                     PART I


Item 1. Business

     The Discover Card Trust 1991 F (the "Trust") was formed pursuant to a
Pooling and Servicing Agreement dated as of November 1, 1991 (the "Pooling and
Servicing Agreement") among Greenwood Trust Company ("Greenwood") as Servicer,
Discover Receivables Financing Group, Inc. ("DRFG") as Seller, and Wilmington
Trust Company as Trustee (the "Trustee").  The Trust's only business is to act
as a passive conduit to permit investment in a pool of retail consumer
receivables.


Item 2. Properties

     The property of the Trust includes a portfolio of receivables (the
"Receivables") arising under selected Discover Card accounts (the "Accounts")
originated by Greenwood, all monies due or to become due in payment of the
Receivables, all proceeds of the Receivables, all monies on deposit in certain
accounts and a certain limited credit enhancement for the exclusive direct
benefit of holders of 8.35% Class B Credit Card Pass-Through Certificates of
the Trust (the "Class B Certificates").  At or prior to the time of the Trust's
formation, Sears, Roebuck and Co. ("Sears") sold or contributed to DRFG,
Receivables existing under the Accounts as of November 1, 1991 and theretofore
acquired by Sears from Greenwood; SCFC Receivables Corp. ("SRC") sold or
contributed to DRFG Receivables existing under the Accounts as of November 1,
1991 and theretofore acquired by SRC from Greenwood; and Greenwood sold to
DRFG, all other Receivables existing under the Accounts as of November 1, 1991
and all Receivables existing under the Accounts from time to time thereafter.
DRFG, in turn, transferred to the Trust all Receivables existing under the
Accounts as of November 1, 1991 and all Receivables arising under the Accounts
from time to time thereafter until the termination of the Trust.  Information
related to the performance of the Receivables during 1996 is set forth in the
ANNUAL AGGREGATE REPORT filed as Exhibit 99(A) to this Annual Report on Form
10-K.


Item 3. Legal Proceedings

     Greenwood is involved from time to time in various legal proceedings that
arise in the ordinary course of its business.  Greenwood does not believe that
the resolution of any of these proceedings will have a material adverse effect
on Greenwood's financial condition or on the Receivables.  There can be no
assurance, however, regarding any of these effects.

Certain legal and administrative proceedings challenged, under the laws of
several states, the imposition of late payment fees (or other incidental
charges) by Greenwood on Discover Cardmembers.  In each of these matters, the
party proceeding against Greenwood claimed that applicable state law
prohibits or limits the imposition of late payment fees, sought to enjoin
Greenwood from imposing late payment fees on Discover Card accounts of
residents of the state in question and sought refunds of (and, in some
cases, civil penalties with respect to) late payment fees previously imposed on
such accounts.  Greenwood asserted a defense in these proceedings that federal
law preempts any state law prohibition against or limitation on


                                      2
<PAGE>   3
charging a late fee payment or other fee with respect to Discover Card
accounts.  On June 3, 1996, the United States Supreme Court issued a decision
holding that state laws limiting late charges are preempted with respect to
national banks by federal law, and the Court remanded for reconsideration
lower-court decisions that had held that such state laws were not similarly
preempted with respect to other federally insured banks.  In light of these
rulings, all of the outstanding legal and administrative proceedings
challenging, on the basis of state law, Greenwood's imposition of late fees and
other incidental charges on Discover Cardmembers were resolved in 1996 in
Greenwood's favor.  No such proceedings are currently pending.

Item 4. Submission of Matters to a Vote of Security Holders

     None


                                    PART II

Item 5. Market for Registrant's Common Equity and Related Stockholder Matters

     The 7.85% Class A Credit Card Pass-Through Certificates (the "Class A
Certificates") and the Class B Certificates are held and delivered in
book-entry form through the facilities of The Depository Trust Company ("DTC"),
a "clearing agency" registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended.  The definitive Class A
Certificates and Class B Certificates are held by Cede & Co., the nominee of
DTC.


Item 9. Changes in and Disagreement with Accountants on Accounting and
          Financial Disclosure

     None


                                    PART III

Item 12. Security Ownership of Certain Beneficial Owners and Management

     As of March 17, 1997, 100% of the Class A Certificates and the Class B
Certificates was held in the nominee name Cede & Co. for beneficial owners.

     As of March 17, 1997, Greenwood and DRFG, as tenants-in-common, held 100%
of the Seller Certificate, which represented beneficial ownership of a residual
interest in the assets of the Trust as provided in the Pooling and Servicing
Agreement.

Item 13. Certain Relationships and Related Transactions

     None
