Such reserves shall at all times be subject to the claims of the Corporation’s creditors. To the extent such trust or other vehicle is established, and assets contributed, for the purpose of fulfilling the Corporation’s obligations hereunder, then such obligation of the Corporation shall be reduced to the extent such assets are utilized to meet its obligations hereunder.
