- Please be aware of the natural limitations of the residual cash functions. These functions don"t have the minute precision of other projections functions.
- There"s no DayCount and Periods, and no ability to calculate the function on a cash basis - if you think about it, this is just not possible given the data inputs.
- The answer will depend to some extent on the value of Base. In other words, in a cashflow where you want to change the Base every so often to run the model on different timebases, don"t expect to get the exact same answers under different timebases. We"ve tried to ensure that in most common cases you do - but again the fundamental data inputs do not permit minute accuracy. For example, a cashflow that has multiple +ve and -ve changes in sign within a timeperiod will necessarily return an "average" result - to capture the detail, you have to run the model on a more detailed timebase.
- All the above having been said, these functions are very useful on the bottom line of most cashflows, since there is no other way to calculate residual interest effects, and these functions are as accurate as you could get.
- Another thing to note about this group of functions is the sign convention. Debt has a +ve balance, cash a -ve one, interest paid is -ve and interest received is +ve, and principal repaid is -ve and principal drawn down +ve.
