13. Environmental Matters

The Corporation is currently performing certain remedial actions in connection with the sale of real estate previously owned. Environmental exposures are difficult to assess and estimate for numerous reasons including lack of reliable data, the multiplicity of possible solutions, the years of remedial and monitoring activity required, and identification of new sites. In the opinion of management and in consideration of advice from the Corporation’s consultants, the potential liability for all environmental proceedings of approximately $1,100 at June 30, 2013 is considered adequate based on information known to date.
