(Assets) What is difference between "Expected Value After Useful Life" and "Value After Depreciation"?


I am struggling to import existing assets (unfortunately not so well documented how to do that for partially depreciated).

Does anyone know what the difference is between the two following columns in the Asset Doctype?

For “Expected Value After Useful Life” the documentation lists the following definition: “Useful Life is the time period over in which the company expects that the asset will be productive. After that period, either the asset is scrapped or sold. In case it is sold, mention the estimated value here. This value is also known as Salvage Value, Scrap Value, or Residual Value.”

What is the purpose of this column “Value After Depreciation (Finance Books)”? Is that a depreciated column in the Asset doctype or what is its function? (sorry for the pun…)
