U.S. Liquids, a liquid waste management company based in Houston, is looking to refinance a $100 million revolver led by Bank of America and Fleet Bank this summer. The existing line was set to mature this month, but has been extended to June 2, after an extension was provided to allow for an audit to be completed, said a source familiar with the situation. The same banks are likely to lead, he added. Earl Blackwell, cfo of U.S. Liquids, confirmed the refinancing, but declined further comment, including potential pricing or exact timing of launch. Pricing on the existing line, reduced from $111 million at the time of the extension, is LIBOR plus 3 3/4%, according to Capital DATA Loanware.
