Neustar successfully submitted its proposal on April 5, 2013, which was the deadline previously announced by the NAPM. The RFP process has been a matter of public record since May 2011, was subject to a robust public comment process, and the deadline for submission of responses was published 60 days in advance of the filing deadline. The process was designed to promote competition and provided interested parties with sufficient time to meet the submission requirements. Neustar filed its response in a timely manner and in accordance with the RFP submission requirements.
