Cost Method Businesses

Actua’s carrying value of its holdings in cost method businesses was $17.3 million as of December 31, 2017 and December 31, 2016, as reflected in the line item "Cost method businesses" in Actua’s Consolidated Balance Sheets.

During the year ended December 31, 2016, Actua increased its interest in Parchment Inc., a cost method business, by $0.7 million. Actua also elected to sell a portion of its interest in InstaMed Holdings Inc. ("InstaMed"), a cost method business, pursuant to a tender offer in September 2016. This sale resulted in a $1.6 million decrease in Actua's interest in InstaMed, as well as a gain of $2.8 million. See Note 12, "Other Income (Loss), Net," for additional information.
