It would appear that it is giving you the BaseAmount for the whole year before where you currently are:

Where are you currently in the Year Group hierarchy? Wherever it is, go back up to the Year. (So, if you were in 14 Feb 2014, go to the year 2014). (That's the ANCESTOR.)

Then go back a year (so, go to the year 2013). (That's the LAG)

Is that reflective in what you see as the result?
