HARTFORD, Conn. (AP) - High-tech manufacturers and other technology-driven companies are urging Connecticut lawmakers to scrap a proposal that would limit the tax credits firms can use for research and development.

Pitney Bowes, a Stamford-based mail and document-managing company, spent about $200 million on research and development last year, much of it in Connecticut. Carole Bilson, a vice president, says the state's R&D tax credit helps Pitney Bowes counterbalance the high cost of doing business in the state.

Paul Pescatello, president and CEO of Connecticut United for Research Excellence, says biophamaceutical companies need to know they can rely on a stable tax environment for years to come. It can cost about $1 billion and take 12 to 15 years to develop some medicines.
