How they deal with Incureable and cureable aspects when doing the Cost approach seems a little odd. They tend to use the ratio of effective age to total economic life for items that relate to Cureable Phsyical depreciation to get the amount of incureable physical deprecation.
But they just subtract out cureable functional, incureable functional without using the ratio method. I’m assuming you only use the ratio of effective age to total economic life when finding the INCUREABLE PHYSICAL depreciation but not the Incureable Function.
It’s a blue box question on page 50. Think that must be the case or is there some logic I’m mssing. Thanks
