In 2009, Roche Holding AG (Roche) made an offer to acquire all remaining outstanding shares of US biotechnology company Genentech. To pay for the deal, Roche planned to sell a record $32 billion in bonds at various maturities from 1 year to 30 years, and in three different currencies (USD, Euro, British pound). For simplicity, let us assume they only issue 10 year dollar-denominated bonds. The 10 year interest rates on corporate bonds, and the median earnings to interest expense ratios (EBITDA/interest expense coverage ratio) for US rated industrial companies at the time were as follows:
Rating | Interest rate | Coverage ratio |
---|---|---|
AAA | 4.0% | 114.0 |
AA | 4.9% | 44.0 |
A | 5.6% | 12.8 |
BBB | 7.0% | 8.2 |
With the acquisition of Genentech, suppose we project that Roche will have earnings (EBITDA) of $23 billion, and their interest expense will be $32 billion (the debt) times the interest rate. If we use the coverage ratio to estimate the bond rating, and we use the bond rating to estimate the interest rate, what rating will we assign to Roche's debt?
AAA
AA
A
BBB
