I need the components of WACC and I need it computed for Starbucks
(2004) in order to continue on my project.  I got stuck on Rd, because
I do not know what the YTM is.

I'm assuming you mean Rd, the average return on the company's debt. If
that's the case, YTM probably stands for yield-to-maturity. Because
bonds have contractually fixed coupon payments (how much interest the
bond pays), the market adjusts the bond's price so that the bonds
YIELD is in line with the market.

Finding the weighted-average YTM for all Starbucks debt may be
difficult... could you use their weighted-average coupon rate instead?
(yes, that's "backward looking" WACC rather than the current market's
assessment, but simple is sometimes better).

I am not sure.  The purpose of finding the WACC is to use it as the
discount rate to discount future dividends to present value.

Starbucks has very little long term debt, but I need the rate that
they pay on their long term debt, or the YTM if they have any bonds.

Hi,

If you're performing valuation using DDM, you should use the cost of
equity capital as the discount rate, not the WACC. You can estimate
the cost of equity capital using CAPM, for example.

You would use WACC as the discount rate, if you were performing
valuation using the free cash flow method (FCFF).
