The National Securities Clearing Corporation (NSCC) is in the process of modernizing the Web applications as some of the technology used to support them is nearing end of life. The initiative is being rolled out in stages, with each application having its own timeline, along with associated important notice and connectivity guide. Depending on the applications used that your firm uses, the impact varies. For further information, view the comprehensive technical network connectivity guide associated with your application.
