Deutsche Bank is shopping a $700 million asset-based refinancing for Maryland-based Williams Scotsman. The company, which operates mobile office and storage unit lease fleets, recently completed a bond deal, said a banker. The credit consists of a $500 million revolver and $200 million term loan, both with five-year maturities. Pricing on the deal is LIBOR plus 3% across the board. Officials at the company could not be reached for comment. BT Commercial Group and NationsBank led the previous credit line arranged in 1997, according to Capital DATA Loanware.
