On March 29, the SEC's Division of Corporation Finance posted a "Sample Letter Sent to Public Companies Asking for Information Related to Repurchase Agreements, Securities Lending Transactions, or Other Transactions Involving the Transfer of Financial Assets." Commonly referred to as a "Dear CFO" letter, the posting of a 'sample' or 'illustrative' letter by the SEC is a way for the agency to communicate to the general public (and to issuers in general) matters of focus for which the SEC is seeking particular information, or reminding registrants of particular reporting requirements.
According to the introductory paragraph above the March 29 Dear CFO Letter, the letter was sent "to certain public companies requesting information about repurchase agreements, securities lending transactions, or other transactions involving the transfer of financial assets with an obligation to repurchase the transferred assets."
The sample letter, signed by staff at the level of Senior Associate Chief Accountant, requests certain information in connection with Corp Fin's review of Form 10-K (the letter specifies which year's 10-K), particularly with respect to repos treated as sales (vs. financings) and regarding repo transactions and right-of-offset.
