Hello! I have probably a silly question but I haven't done this for a while...! I was wondering if someone could walk me through how to calculate a single equivalent discount rate by hand? For example, if we take the first 5 years of the gilt curve as at 28 Feb 2019 (just for ease, but hoping this method extrapolates out for the whole curve!) how I would I calculate the single equivalent? Year Gilt 1 0.771001 2 0.802474 3 0.856910 4 0.917013 5 0.974830 Thanks in advance!
