One number that shot up was the cost of subscription products which hit $167.3 million in the most recently ended year, a rise of 25.6 percent from $133.2 million in 2014.

Net income was dented by increased amortization of finite-lived intangible assets arising from acquisitions, as well as increased stock-based compensation.
