The 10-Year Treasury is an index rate; a published interest rate (or interpolation of rates) usually corresponding to the current yield of a US Treasury note or bond, Prime Rate, LIBOR, etc. The Final Note Rate is typically equal to the sum of the index rate plus the spread. Index rate yields are typically published in daily papers by financial information services (e.g. Wall Street Journal, Bloomberg). Daily rates can be seen to the right in the helpful resources.
