I'm a bit confused about dealing with situations in which you are presented with XD adjustment and income (and also, to make things particularly jolly, tax).
For example assignment X4 Question 9 part (iv) gives;
- a series of capital values I(t);
- a series of XD adjustments XD(t);
- a series of accrued interest amounts Acc(t).
It asks you to calculate a suitable total return against which to measure a fund over a three month period, assuming the fund pays 30% tax on income (only).
The solution gives the following formula for the total return from one period to the next;
TR(t-1,t) = {I(t) +(1-T) [XD(t)-XD(t-1)]-T(Acc(t)-Acc(t-1))}/I(t-1)
Right, I get the bit about stripping out the tax on the XD series at the rate at which the fund is paying tax. However, it's the accrued interest bit that baffles me. I thought the XD adjustment itself was supposed to represent income (in this case coupon payments) over the year to date. In that case, what's the second adjustment about? Is it interest on the income?
Please let me know if anyone has any thoughts on this.
Thanks
