RSC Holdings last week announced that David Mathieson, senior vice president and chief financial officer, is leaving the company to pursue other opportunities. Patricia Chiodo, currently the company’s vice president and controller, will serve as interim chief financial officer while the company conducts a search for his successor. The transition is effective immediately; in addition, Mathieson will be available to assist in transition matters as needed.

“I’d like to thank David for his contributions to RSC, including his assistance on several important debt offerings and cost reduction efforts that helped the company effectively navigate through the recent difficult economic environment,” said Erik Olsson, president and CEO “With our business performing in line with the guidance we provided in February and the environment recovering as anticipated, the company is positioned to emerge from the recession with the strongest possible team.”

The company has commenced a nationwide search for a new chief financial officer who will continue to build out a best-in-class finance function and work collaboratively with the rest of senior management to set corporate strategy and support the operations of the business toward generating superior shareholder value.

“We are fortunate to have a first-rate finance team in place that will assure the seamless operation of our department during this interim period and pleased that David will be available to assure a smooth transition,” Olsson concluded.

RSC Holdings, based in Scottsdale, Ariz., is the holding company for the operating entity RSC Equipment Rental, which is No. 2 on the RER 100.
