On February 24, 2016, Jimmy Mar and Dan Rubin presented a lecture on the freemium business model and network economies to an upper-division Applied Finance class at the University of California, San Diego. Specifically, Mr. Mar and Mr. Rubin discussed different pricing strategies within a freemium model and how changing customer demographics present challenges to growing a user base in network economies. They also discussed the attrition rates of different customer groups and the implications of attrition rates with regard to the valuation of key intangible assets and goodwill recognized in recent acquisitions. Mr. Mar and Mr. Rubin drew upon their experience helping clients with purchase price allocations for financial reporting purposes under ASC 805 and the impairment testing of long-lived assets under ASC 360.
