MAJOR CUSTOMERS AND CONCENTRATIONS OF CREDIT RISK

NOTE I – MAJOR CUSTOMERS AND CONCENTRATIONS OF CREDIT RISK

Major Customers

For the fiscal quarter ended June 30, 2012, General Chemical Corporation, Suffolk Sales and SGR Energy LLC accounted for approximately 17%, 16% and 15% of Regional’s revenues, respectively, and approximately 28%, 25% and 3% of Regional’s accounts receivable, respectively. MeadWestvaco Specialty Chemicals, Inc., accounted for 5% of Regional's revenues and 10% of Regional's accounts receivables. No other individual customer accounted for more than 10% of Regional's revenues and accounts receivable.

Concentrations of Credit Risk

The balance sheet items that potentially subject Central to concentrations of credit risk are primarily cash and cash equivalents and accounts receivable. Central maintains cash balances in different financial institutions. Balances in accounts other than “Noninterest-Bearing Transaction Accounts” are insured up to Federal Deposit Insurance Corporation (FDIC) limits of $250,000 per institution. Noninterest-Bearing Transaction Accounts have unlimited FDIC insurance coverage through December 31, 2012. At June 30, 2012, Central did not have any cash balances in financial institutions in excess of FDIC insurance coverage. Concentrations of credit risk with Regional’s accounts receivable are mitigated by Regional’s ongoing credit evaluations of its customers.
