[1] Revenue information provided for each segment includes amounts grouped as Interest and other in the accompanying statements of operations. Corporate revenue is net of an intercompany revenue elimination.

[2] Interest expense (income), net for Newsstand Distribution Services and Corporate and Other principally includes inter-segment interest income that is eliminated in consolidation.

[3] The Company uses EBITDA (which the Company defines as income before net interest expense, income taxes, depreciation and amortization, and non-cash impairment charges) in addition to net income (loss) as a key measure of profit or loss for segment performance and evaluation purposes.
