Adequate Reserves for Repairs of Environmental Damage

Pollution cleanups are often costly, and there is a good likelihood that a cleanup may cause a heavy loss to business.
Ricoh sets aside adequate reserves for possible future losses from repairs of environmental damage based on reasonable cost estimates.
As of March 31, 2010, Ricoh had set aside ¥970 million in reserves for soil purification.
