Is my money that I have on deposit at SCU Credit Union insured?

Your money is insured by the National Credit Union Administration (NCUA), an independent agency of the United States Government. Your savings is federally insured up to $250,000 and backed by the full faith and credit of the United States Government.

The shares and deposits of the credit union in excess of NCUA limits are fully insured by the Massachusetts Credit Union Share Insurance Corporation (MSIC). Your money is 100% insured regardless of the amount at SCU Credit Union. MSIC provides Excess Share and Deposit Insurance to all members of SCU Credit Union automatically. The coverage is a benefit of membership and comes at no direct cost to you. MSIC insures the portion of any legal, verifiable share or deposit account that exceeds NCUSIF coverage with no limit.
