Nearly 78 percent of exchange company Nasdaq OMX Group’s bond offering is tendered to its $428 million repurchase offer, The Wall Street Journal reports. Notes worth $334.7 million are validly tendered and not withdrawn. The convertible senior notes, which carry a coupon rate of 2.5 percent, are due to mature in 2013.

Nasdaq is seeking to cut down its borrowing costs and lengthen the maturity profile of its debt obligations. The offer was launched in September along with a five-year $1.2 billion senior unsecured credit facility.
