So what

YY reported fourth-quarter revenue of 4.64 billion renminbi, about $675 million. This was up 28% from the year-ago quarter. Non-GAAP (generally accepted accounting principles) earnings per share for the period was $1.87, down from $2.27 in the year-ago quarter. 

On average, analysts were expecting revenue of $667 million and non-GAAP EPS of $1.77. 

The company's strong top-line growth was driven by an 18.1% year-over-year increase in mobile live streaming monthly active users and a 36.6% year-over-year increase in live streaming paying users.
