Pro Forma EBITDA is a supplemental non-GAAPfinancial measure that InterDigital uses for compensation purposes as described in this proxy statement. InterDigital defines Pro Forma EBITDA as total revenues minus operating expenses plus depreciation and amortization, intellectual property enforcement costs, and other items. Other items include restructuring costs, impairment charges and other non-recurringitems, as further described below. This non-GAAPfinancial measure may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. A detailed reconciliation of Pro Forma EBITDA to the most directly comparable GAAP financial measure is provided below.
