Investopedia explains 'Auction Rate Security - ARS'
In essence, an auction rate security is a long-term debt issue, but it acts as if it were a shorter term issue. This is because interest rates are reset approximately every month, depending on whether the issue is tax exempt, and the interest is paid either shortly after the auction yield is settled or every quarter or half year.
