rf / PS (it looks like a KLUDGE or some sort of MacGyverism)
rf is the market risk free rate as read from the Temporary Structure Of Interest Rate or Yield Curve. PS is the probability of success for the Corporation or (1-Probability Of Default)
This is the catch! Probability of Default or Probability Of Success is not easy to get. You will need to run an algorithm entitled: Altman Z-Score (by Professor Edward I. Altman) with the following figures belonging to a "Columbian" Corporation listed on BVC:
Working Capital=333,060,600
Total Assets=1312,650,600
EBIT=117,550,800
Sales=2546,934,000
Market value of equity is :744,488,400
Total Liabilites: 470,203,200
Retained Earnings: 587,754,000
- T1 = Working Capital / Total Assets
- T2 = Retained Earnings / Total Assets
- T3 = Earnings Before Interest and Taxes / Total Assets
- T4 = Market Value of Equity / Total Liabilities
- T5 = Sales/ Total Assets
- Z = 1.2T1 + 1.4T2 + 3.3T3 + 0.6T4 + .999T5
- Z > 2.99 -“Safe” Zones
- 1.81 < Z < 2.99 -“Gray” Zones
- Z < 1.81 -“Distress” Zones
The Altman Z-Score is a Gaussian statistic and for this corporation = 4.11522388059702. This means a probability of success = 0.999980659810466 (you can use NORMSDIST function embedded on any spreadsheet to get this value)
The very same day these Financial Reports were issued, the "Columbian" yield curve for a 10 year Bond is 7.84% after applying our formula and if we want to issue our Corporate Bond our cost would be 7.8402%
Is this cost a straight jacket or alluring to investors? maybe not! you have to compare this one to the cost you would face if you were taking a loan from a bank or an ensemble of them. So thus, the coupon rate of your bond could be defined by the following interval [rf, ActiveRate]
After all, other than full control and a lower cost of corporate debts you are looking for an arbitrage opportunity. The cheapest bank in this country is paying on a 10 year CD 8% and for a 10 year loan is collecting 16% a year...Our new coupon rate would be 0.08/0.999980659810466 = 8.000154725%
Either a bank or the yield curve. The day this debt is issued to be market traded, the market's discount rate will be higher than your coupon rate...Beware of not selling your bonds at a discount rate near or above the cost of a loan from any Bank....
WHAT IF? By using the yield curve the key reference rate is negative? No problem, at least one of the rates per maturity will be positive....We can use this one to build our Yield curve by applying calculation of the short rate curve
