The latest document regarding the disclosure of certain information about lobbyist-bundled contributions is the Notice of Proposed Rulemaking. In this November 2007 document the Commission wrote:
The Commission expects that these proposed rules will become final in early 2008, and that the new disclosure requirements will apply to reports filed three months later. Thus, the first semi-annual reporting period would be January 1 through June 30, 2008, and the first quarterly reporting period would be April through June, 2008.
As of this writing, the rules have not been made final.
