The actual results of BGC Partners, Inc. ("we," "our" or "the Combined Company") and the outcome and timing of certain events may differ significantly from the expectations discussed in the forward-looking statements. Factors that might cause or contribute to such a discrepancy for the Combined Company include, but are not limited to, our relationship with Cantor and its affiliates and any related conflicts of interests, competition for and retention of brokers and other managers and key employees, pricing and commissions and market position with respect to any of our products, and that of our competitors, the effect of industry concentration and consolidation, and market conditions, including trading volume and volatility, as well as economic or geopolitical conditions or uncertainties. Results may also be impacted by the extensive regulation of our businesses and risks relating to compliance matters, as well as factors related to specific transactions or series of transactions, including credit, performance and unmatched principal risk as well as counterparty failure.
