Side letter

Definition

An informal or undisclosed written agreement between a buyer and seller that modifies the terms of the primary contract. Side letters are a primary vehicle for revenue fraud because they may grant informal return rights, extend payment terms, or condition the sale on future events, each of which would prevent revenue recognition under IFRS 15 or ASC 606.
