Lazard Group intends to use a portion of the net proceeds from the Offering to repurchase or redeem up to $250 million aggregate principal amount of the 2020 Notes, and to pay fees and expenses related to the foregoing, and to use the remaining amount for general corporate purposes, including potential repurchases of shares of Lazard Ltd’s Class A common stock.
