Discover Card Misclassification, page 17

1.     As it relates to Discover management   s incorrect classification of
Consumer cards as
       Commercial cards, and as we relayed in a telephone conference with
Discover   s
       management on October 2, 2024, we have considered the information
conveyed in
       both your letter dated September 3, 2024 and during a conference call
with Discover   s
       management on September 17, 2024. Based on that information, we object
to the
       Company   s methodology for the correction of errors in the application
of ASC 605,
       Revenue Recognition, as well as ASC 606, Revenue from Contracts with
Customers.
       Please provide to us a revised analysis that reassesses the methodology
it has
       employed to correct the revenue errors under ASC 250 related to the
incorrect
       classification of Consumer cards as Commercial cards, including how you
propose to
       correct your historical financial statements. The reassessment should
contemplate the
       Consumer rates and tiers in effect during the respective periods and the
historical

       classification of properly classified Consumer cards in those respective
periods.
2.     Explain whether any additional analysis is required under other relevant
GAAP and
       provide us with a supporting analysis with specific citation to relevant
accounting
       guidance. For example, this analysis should explain whether any
additional liabilities
       were required to be recognized, the type of liability that results from
the revenue
       correction (e.g., refund liability, financial liability, contingent
liability, etc.) as well as
       the appropriateness of disclosures previously provided. This analysis
should also
       address whether and how your subsequent accounting after the second
quarter of 2023
       will be revised as a result of your reevaluation.
3.     Provide a comprehensive materiality analysis, addressing both accounting
and
       disclosure.
4.     We acknowledge the October 4, 2024 letter provided by Discover Financial
Services,
       in connection with our review of their December 31, 2023 Form 10-K, in
which
       Discover   s management confirms that they will also consider our
objection noted
       above in responding to the comments in our letter dated September 20,
2024 related to
       internal control over financial reporting.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence
of action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.
