5. Noncontrolling Interest
Prior to October 2012, the Company owned 49.94% of the total capital stock of DC Bio. As of December 31, 2011, the other shareholders’ ownership interests in DC Bio were represented on the consolidated balance sheet by noncontrolling interest as a separate component of stockholders’ (deficit) equity. In October 2012 and December 2012, DC Bio repurchased the noncontrolling interests from these shareholders. Subsequent to these transactions, the Company owned 100% of DC Bio and eliminated its equity attributable to non-controlling interest through additional paid-in capital.
