Operator Ladies and gentlemen, thank you for standing by, and welcome to ADTRAN's First Quarter 2021 Earnings Release Conference Call. [Operator Instructions] During the course of the conference call, ADTRAN representatives expect to make forward-looking statements, which reflect management's best judgments based on factors currently known. However, these statements involve risks and uncertainties, including the continued spread and expense of the impact of COVID-19 global pandemic, the ability of component supplies to align with customer demand, the successful development and market acceptance of our products; competition in the market for such products, the product and channel mix, component costs, manufacturing efficiencies and other risks detailed in our annual report on Form 10-K for the year ending December 31, 2020. These risks and uncertainties could cause actual results to differ materially from those in the forward-looking statements, which may be made during the call.
