MediMedia USA Inc. is looking at some debt maturities and interest payments in the coming year that likely will strain the health care media marketing company's liquidity further, Dow Jones DBR Small Capt reported today. The Yardley, Pa.-based company, which is owned by private equity firm Vestar Capital Partners, paid down some of its revolving credit facility and term loan and pushed maturities out last year after selling its veterinary unit to VCA Antech Inc. for $146 million in August 2011. Still, about $15 million of the $45 million revolver matures later this year, and another $6 million of the term loan is due next year.
