Nothing more than date of, and I'm sure that at this particular time with said changes occurring, the only home/office phone might be if you called:
"Company appointed Mr. Mark Dresner to serve as the new Chief Executive Officer and a director of the Company." at his home if you can track him down.
I've done that in the past calling a new company/ceo/shell but I'd advise against it. I really pissed the person off at the time, and had nothing to say, lol
