Letter of transmittal
In Finance, a letter of transmittal is a document used by a security holder to accompany certificates surrendered in an exchange or other corporate action.
Transmittal letters often accompany reports and inform of a report's context. Typically, the letter includes information not found in the report. For example, the letter contains information about the particular project and/or due dates. A Transmittal Letter is a business letter and should be formatted accordingly; that is, you should include the recipient's address, your address, a salutation and closing. Depending on the project, you may also need to include contact information. Always check with your instructor to determine whether or not you should attach a transmittal letter to your report.
