D4 Holdings LLC, owner of American Communications Network, on Thursday completed its takeover of VoIP provider deltathree Inc. (DDDC.OB)

The transaction closed just nine days after the companies announced that D4 Holdings would buy a 54.3 percent stake in deltathree, whose business has crumbled under management changes and money troubles including declining sales.

So what’s next for deltathree under D4’s auspices? There’s not much information beyond a D4 Holdings statement issued earlier today.

“We are delighted to welcome deltathree into our strategic portfolio, and look forward to realizing the synergies that are so immediately apparent between deltathree and our other entities,” Robert Stevanovski of D4 Holdings.

Readily apparent to D4 Holdings, maybe, but not necessarily to the rest of us.
