The purpose of the calls was to request that a vote be made so that a quorum would be met as required in order for the vote to be valid. If a quorum does not vote the expense of a new vote would be needed. A quorum is the minimum number of votes of shares outstanding necessary to conduct the business of the Company. Ordinarily, this is a majority of shares outstanding.
I do not understand why anyone would want the Company to buy back stock or otherwise prop up the PPS with its cash even it they could. We know how dearly we have paid to obtain the cash the Company has. Our salvation, if we are to be saved, is IMHO in the development of a successful product(s). We have very little time or money to accomplish that.
It should be noted again that the Company had to agree to allow the "rats" to veto any use of money obtained in the sell of any Company asset as all assets of the Company are security for the loan of money the "rats" made to the Company.
