shelf registration

Explanation:

The delay between registering new securities with the securities exchange commission and selling them can be avoided by use of shelf-registration.

Shelf registration, is a form of public offering whereby some issuers can offer and also be able to sell their securities to the public such that a separate prospectus isn't required for each offering and also a further prospectus isn't required as well.

The main advantage of the shelf registration is that it's timely and certain such that the capital markets can be accessed even when it's required.
