Description of reclassification result       The company has revised its classification of deferred consideration payments associated with our acquisition of TCI in September 2012. The previously reported condensed consolidated statement of cash flows was changed to reflect a reclassification resulting in a $1 million increase in cash flows from operating activities and a corresponding decrease in cash flows from financing activities. The revision had no impact on the Company’s financial position or net income for the periods impacted.
