The state of Delaware says the company authorized the reverse. The transfer agent acknowleges the documents submitted. NASDAQ approved the reverse and stated so. The stock charts reflect the 1:200 reverse. DTC acknowleges the reverse.
Where in this equation would there be a concern that somehow it wouldn't happen ?
Of course, selling the old DCUT, risks a short buy-back if the certs are not delivered in time....but, that is the owners' decision.
