AFMChapter 8 (valuation of debt finance)

Hi Mr John, Just want to make sure that I got few things in chapter 8 right: - Is the (gross redemption yield) and the (redemption yield) the same thing? - The Gross redemption yield is the same thing as the required rate of return by investors, which equals IRR. (correct?) - The only difference between the gross redemption yield and the cost to the company (kd), is that when we come to calculate the IRR, we take account for the tax relief in the interest rate bit. Thank you, I just like to be certain about the basics as although my questions seem simple, these things could cause a great confusion later if I am wrong about them Regards, Maha
