There's definitely a pecking order to the choice if you are not given K(d) from the get go.

1. I would first use the YTM on future issues (Like we said above)
2. YTM on most recent issue
3. If given S/T Debt & L/T Debt and int I would calculate the weightings of each portion of debt and then multiply that by the firm's int pmt.
4. YTM on S/T Debt

I think you would use the coupon pmts as a last resort. This is from the top of my head so let me check my notes.
