Wachovia Securities is leading the $160 million credit facility backing ceramics manufacturer Ceradyne's $136 million acquisition of ESK Ceramics from German silicon and chemical manufacturer Wacker-Chemie. The deal comprises a five-year, $50 million revolver and seven-year, $110 million "B" loan. Price talk is LIBOR plus 2% on the revolver and LIBOR plus 2 1/2% on the "B" loan. Pro forma leverage will be around 2.3 times. ESK, a producer of technical ceramics and non-oxide powers, was purchased by Wacker-Chemie in 1933. Wachovia bankers and Jerry Pellizzon, Ceradyne's cfo, did not return calls.
