10.Common Stock The following transactions occurred during the years ended December 31, 2017, 2016 and 2015: Reverse Stock Split On May 5, 2017, the Company effected a one-for-ten reverse stock split of the outstanding shares of the Company’s common stock, together with a corresponding proportional reduction in the number of authorized shares of the Company’s capital stock. Each ten shares of the Company’s common stock, par value $0.0001 per share, issued and outstanding at the effective time of the reverse stock split were reclassified and combined into one share of common stock par value $0.0001 per share.
