Essilor has carried out the private placement of $300 million worth of notes with 18 investors in the U.S. The senior unsecured notes will help refinance a bank loan due in 2014, while extending the maturity of its debt and broadening its base of investors. The maturities of the notes range from 2017 to 2023, and the ten-year tranche offers a favorable 3.4 percent rate for the annual coupon. Essilor had initially announced a $150 million transaction, but it was more than seven times oversubscribed.
