Note 11—Concentrations and Associated Credit Risk

The Company holds cash, cash equivalents, and restricted cash at several major financial institutions, which may exceed FDIC insured limits. Historically, the Company has not experienced any losses due to such concentration of credit risk. The Company’s temporary cash investments policy is to limit the dollar amount of investments with any one financial institution and monitor the credit ratings of those institutions. While the Company may be exposed to credit losses due to the nonperformance of the holders of its deposits, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows or financial condition.

Utility companies offer purchase of receivable programs in most of the service territories in which GRE’s REPs operate. GRE’s REPs reduce their customer credit risk by participating in POR programs for a majority of their receivables. In addition to providing billing and collection services, utility companies purchase those REPs’ receivables and assume all credit risk without recourse to those REPs. GRE’s REPs’ primary credit risk is therefore nonpayment by the utility companies. Certain of the utility companies represent significant portions of GRE’s REPs’ revenues and gross trade accounts receivable balance and such concentrations increase the risk associated with nonpayment by those utility companies.
