The National Credit Union Administration (NCUA), a U.S. government agency, insures your account up to $250,000 per member. When your accounts exceed $250,000, the maximum level of coverage provided through NCUA, you are also insured up to an additional $250,000. Your board of directors has chosen to provide this exceptional level of insurance through a private company. This supplemental insurance is provided by Excess Share Insurance (ESI) Corporation. ESI is a subsidiary of American Share Insurance, the nation's largest private deposit insurer for credit unions. Excess share insurance is available only to credit unions meeting the company's rigid requirements and standards of performance.
