Just to add, Ameridan's approach also deals with how you can record the distribution for the purposes of Income Tax on the distribution (noting that there is no Income Tax on the equalisation payment, as that is a repayment of capital), if you later want to produce a report for Income Tax purposes. TBH, I don't bother with that step in my non-taxable accounts (SIPPs, ISAs) because it seems rather pointless as there are no tax reporting requirements/no tax to pay (I also don't bother recording the equalisation payment/its accumulation as a return of capital transaction, given that there is no Capital Gains Tax to pay in these accounts) . I also suspect that it may distort the return calculations (TR All, Ann. Ret.) shown in the Portfolio Manager - as income has simply been rolled-up within the fund, the income is already reflected in the unit price. Hence, assuming that there haven’t been any further transactions since the original purchase, the correct way to calculate total return would be ((current value - initial value) / initial value), whereas including the phantom distribution would make it ((current value - initial value + income) / initial value), potentially showing a higher and inaccurate return. Albeit I appreciate that also having the reinvestment of the distribution as a return of capital transaction would then make the calculation ((current value - initial value + income - return of capital) / initial value) ..... ignoring any time weighting/money weighting of the income and return of capital amounts, and with the income and return of capital amounts cancelling each other out if they have the same value. Hence in order to get accurate return numbers, you either have to enter both the income distribution and its reinvestment (as a negative ROC transaction), or neither of them.
As I mentioned, as these are cashless transactions on ACCumulation units, you can make them cashless by deleting out the "Transfer to:" account. But Ameridan's suggestion of having two transactions which zero out each other out in your cash account will work as well, if you are happy to have two phantom cash transactions in that account.
On the subject of the TR All and Ann. Ret. calculations, it would be interesting to know if any members of this group have any insight into the calculations that sit behind those calculations. I've always assumed that they are relatively simple money-weighted returns (IRRs) rather than being time-weighted returns (TWRs), but it would be interesting to understand how the timing of each transaction (Buy, Sell, Dividend, Return of Capital, etc) is taken into account in the calculations, particularly if there is a Buy, followed by a partial Sell, followed by another Buy, followed by another partial Sell. The calculations appear to produce very odd results when there is a Buy, followed by a total Sell, followed by a Buy. I would expect the returns which then show to only be based on the second Buy and the value of that shareholding (including any dividends received since that Buy), but it appears to me that the returns produced by the previous holding which was sold in its entirety are also rolled into the calculations. Hence where there are partial Sells I’m not sure how accurate the returns are.
