A comfort letter is a document prepared by an accounting firm assuring the financial soundness or backing of a company.[1] The comfort letter can be issued by a CPA declaring no indication of false or misleading information in the financial statements and that the company's prospectus follows GAAP. This is sometimes used in connection with an initial public offering.[2] Comfort letters are also sometimes provided by those involved in evaluating a company's assets, for instance, in the case of oil and gas companies, third-party reserve engineering firms.
A comfort letter may also be used as written assurance by a subsidiary's parent company or bank used to offer 'comfort' to the buyer as to the seller's ability or willingness to perform its obligations. Comfort letters are often used because the seller is unable or unwilling to provide a guarantee on a certain outcome, such as the performance of a security.[3]
Comfort letters are typically signed prior to the pricing decision or closing date for a given public offering or other transaction, as a part of the due diligence process. Subsequently, a "bring-down" letter is used to re-verify, as of a later date, that the original comfort letter is still valid.
The legal and accounting circumstances surrounding comfort letters were the subject of a 1975 novel,[4] The Comfort Letter by Arthur R.G. Solmssen, a Philadelphia lawyer and novelist.
Letter of Comfort (LOU) in finance terminology is a type guarantee provided by one bank to other bank. Letter of Comfort is also used by importers to arrange funds in products like buyers credit.
