Accounting Treatment for fee Income

Hi guys, I have question in regard of accounting treatment for fee income such as ( management fee, Up front fee and commitment fee). Do you think such fees should be Amortization over the loan period and is this accounting treatment is inline with IFRS and International GAAP?
I had a serious discussion with our accountant adviser and he said the following:

According to International Accounting Standard # 18 (illustrative example related to rendering of services para 14) which states:

"Fees received by the entity relating to the creation or acquisition of a financial asset, such fees may include compensation for activities such as evaluating the borrower's financial condition, evaluating and recording guarantees, collateral and other security arrangements, negotiating the terms of the instrument, preparing and processing documents and closing the transaction. These fees are an integral part of generating an involvement with the resulting financial instrument and, together with the related transaction costs (as defined in IAS 39), are deferred and recognised as an adjustment to the effective interest rate."

as result fees related to evaluation of borrower's financial condition should be deferred and recognized as an adjustment to the effective interest rate.

What is your opinion in regards of such fee and do you believe such fee should not be amortized?

Thanks in advance for your contribution and input
