12. Cash Dividends
 
On January 26, 2016, our board of directors declared a quarterly dividend of $0.05 per share of common stock to stockholders of record on March 4, 2016. On March 11, 2016, we paid $8.2 million in connection with such dividend payment. Unvested RSAs as of the record date are also entitled to dividends, which will only be paid when the RSAs vest and are released.
