[1] Cash flows in 2013 include the $25.0 million gain from the sale of RGSE stock, the sale of GVE and the discontinuation of the DRTV Business Unit.
[2] Net cash provided by operating activities for discontinued operations during 2012 includes approximately $18.7 million of net cash provided by purchased Vivendi Entertainment ("Vivendi") working capital, which was used to partially fund the acquisition of Vivendi. Excluding the net cash flows from the purchased Vivendi working capital, net cash used by operating activities for discontinued operations would have been zero during 2012.
