Mezzanine Financing is usually at 13%-25% interest with a convertible feature which cant be converted unless the loan is truly in default.....They usually are not very long term loans..
As for the 10Q info....Your concern about the info contained within is justified....More than likely they will just list it under the "subsequent events" section as an FYI feature to shareholders possibly with details of the terms of the loan...
They are saying that the 10Q is being held up until this deal is finalized and this information is added to the 10Q...
Whether this happens as they say remains to be seen...
