Schedule of Unrecognized Tax Benefits Roll Forward
Included in the balance of total unrecognized tax benefits at December 31, 2016 are potential benefits of $3.4 million, which if recognized, would affect the effective rate on income from continuing operations. Given the Company's current valuation allowance position, no benefit is expected to result from the reversal of any uncertain tax position associated with the acquired U.S. attributes.
