looking at IRR as a comparison to folio ytm. I am using the following as the stream of cash flows for the IRR...

[-ask+accrued int] as the first amount and then each of the remaining payments less the 1% fee.

i am getting a fairly consistent .3 to.55 higher than the folio calculated ytm which i am thinking may have something to do with the fact that I am taking into account accrued interest in the first amount.... not sure if folio is?

my question is that every now and then i will come across a note where my calculated IRR is 1.5 to 2.0 hight than the folio ytm. when i look at these notes, i cant find anything out of the ordinary from the others that mostly seem in line with my calculations. any ideas? here is an example.

my IRR uses [-66+.37] as the first cash flow and then 23 payments of [3.16-.03] as the remaining
