Intro: Uncle Sam guarantees that deposits at banks are insured up to a hundred thousand dollars. But even if you don?t have nearly that much in a bank, you should still understand how the system works. Bankrate.com makes it easy…

Voice over 1: Its common knowledge that the federal deposit insurance corporation insures bank deposits up to $100,000.

Voice over 2: (Cover with banking video) But even if you don?t have 100 grand in a bank now, maybe you know someone who does?like a grandparent for example. What if the bank goes bust?

Voice over 3: It’s happened before: When Superior Bank in Hillsdale, IL went under, 65 million dollars of excess…and thus uninsured… deposits were lost. In another instance, Hamilton Bank in Miami went under, and 94 million dollars was uninsured.

Voice over 4: (Cover with banking video) So this stuff does happen: maybe because the rules are trickier than they seem.

Voice over 5: (Money Video. Freeze and add Chyron: Insured Deposits? 1. In Grandma?s Name: $100,000 2. In joint name, with Grandma and Junior: $100,000. Covered) For example, say grandma has two $100,000 savings accounts. One is just in her name, the other is a joint account with Junior. The bank goes under. Are both accounts covered? (Add ?Covered? here, maybe like a big stamp.) Yes, because technically they have different owners.

Voice over 6: (Money Video. Freeze and add Chyron as discussed: Insured Deposits? 1. In Grandma?s Name: $100,000 2. In Grandma?s name, payable on death to junior: $100,000.) Now say Grandma has the same Savings Accounts. One is her name alone. The other is in her name, but with Junior as beneficiary, payable on her death. Again, two different accounts. But are both insured? (Add ?Not Covered? here) No. So how accounts are titled can make all the difference.

STANDUP: Bottom line? If you?re even close to going over the $100,000 mark at a bank, do some homework. Because there are few situations where the devil is more in the details. For Bankrate.com, I’m Kristin Arnold.
