LONDON, Oct 4 Sanofi-Aventis SA (SASY.PA) will
pay initial interest rates of less than 1 percent on the $15
billion of loans backing its hostile bid for U.S. rare-disease
specialist Genzyme Corp GENZ.O, a regulatory filing showed.
On Monday the French drugmaker went hostile with its $18.5
billion bid for Genzyme, taking the offer directly to
shareholders after being rebuffed by Genzyme management.
Sanofi Chief Executive Chris Viehbacher is benefiting from
what he terms "cheap debt", fuelled by ultra-low benchmark rates
and a revival in the market for acquisition finance.
Sanofi has arranged $10 billion of 18-month loans,
extendable for another six months, and $5 billion of 3-1/2 year
loans with BNP Paribas, JPMorgan and Societe Generale.
It is paying an initial average of just 93.2 basis points,
according to Reuters calculations.
The shorter loans pay a margin of just 55 basis points, or
0.55 percentage points, over inter-bank rates for the first
three months, a Securities and Exchange Commission (SEC) filing
With 3-month dollar LIBOR USD3MFSR=, over which such loans
are typically priced, standing at 0.29063 percent, that implies
an all-in borrowing cost of about 84 basis points.
The longer-term loan depends on Sanofi's credit ratings --
currently AA- from Standard & Poor's and A1, or the equivalent
of one notch lower, from Moody's Investors Service. That gives a
blended margin of 82.5 basis points.
The premiums are thinner than those on the $45 billion of
loans backing BHP Billiton's pursuit of Potash Corporation of
Saskatchewan Inc (POT.TO).
The miner, whose S&P rating is one notch lower, has agreed a
loan package including $25 billion of 1-year loans at 70 basis
Margins on Sanofi's $10 billion loan rise 20 bps every three
months for the first year, and 30 bps for the following two
quarters, so that after 15 months they are paying 1.75 percent.
The $5 billion loan pays more if Sanofi's credit standing
