*The current Market-Clearing Yield/Final Auction Yield is calculated as Yield to Worst (YTW) which is the lowest yield of yield to maturity, yield to call, yield to put, or other yields when a bond is callable, puttable, exchangeable, or has other features. If a bond is called, put or exchanged before maturity, the bondholder only earns interest on the time that has elapsed between purchasing the bond and its early redemption. The resulting yield is less than what would have been earned had the bond been held until maturity.
