@MrMoody - Yeah, I agree. You need to calculate the true loan cost with any loan you take to finance your business, to know if you are really getting a good deal.
Corporations report on their outstanding loans in their financial statements and loans are one of those figures that help to reflect on the financial state of the business, in addition to the accounting method use, like the article says.
On that point, I think a really savvy investor looking at the financial statement should understand the meaning of the different accounting methods. It’s quite possible that a set of figures reported using an accrual method would look different if reported through some other method, and lead the investor to a different conclusion about the company’s financial picture.
