This memorandum discusses Groupon's use of non-GAAP financial measures in its S-1 and S-1/A filings. Specifically, it focuses on Groupon's exclusion of online marketing expenses from its adjusted consolidated segment operating income (ACSOI) measure. The SEC has questioned this exclusion, as online marketing represents a normal recurring operating expense for Groupon and excluding it could mislead readers. While Groupon claims marketing expenses are not indicative of future expenses, it also states these expenses are based on the growth it wishes to pursue. Therefore, the SEC argues exclusion of marketing is not justified as Groupon's business relies on acquiring new customers regularly through online marketing. The memorandum agrees with the SEC's position. It
