The lender said it previously allocated about $500 million of bonds to syndicate brokers in the bookbuild conducted on 25 November 2010, and raised an additional $70 million from a security holder and customer offer.
In total, 5.7 million bonds were issued at $100 each and the CommBank Retail Bonds have started trading on the Australian Securities Exchange under the code CBAHA.
"We are pleased to have completed our first series of CommBank Retail Bonds and thank everyone that has participated in the offer," CBA chief financial officer David Craig said.
"This transaction has given investors an opportunity to diversify their investment portfolio and demonstrates our commitment to developing the Australian retail corporate bond market."
Additionally, CBA said it will pay interest of $1.85 per CommBank Retail Bond Series 1 Tranche A security on 15 April 2011.
