IN F7 i have learned that non current liability should be recorded at present value i can calculate it but i am unable to understand that why we need to record at present value what is the reason behid this concept
Sorry, but I’m not too sure what you mean in your question. Amounts shown in non-current liabilities are measured using whichever is the correct method. This could be the present value of future cash flows if it is a financial liability but will be different for other balances such as deferred tax.
