Commonwealth Bank completed the retail component of its entitlement offer on Friday, raising A$1.5 billion dollars and leaving it with some work to do to reach the target it set when it launched its capital raising last month.On August 12 the bank said it would raise $5 billion of capital through a pro rata (one new share for every 23 shares held) renounceable entitlement offer at $71.50 a share.A week later it completed the institutional offer and bookbuild, raising $2.1 billion.The bank is still looking for around $1.4 billion of equity capital and on Friday it announced that the entitlements of eligible shareholders who did not participate in the retail entitlement offer and of ineligible retail shareholders (about 21 million entitlements) would be offered for sale through a bookbuild to institutional investors, starting that day.The take-up of the retail component of the offer is a disappointment for the bank, which had expected it to raise $3 billion.Following the completion of the capital raising the bank expects to have a common equity tier one capital ratio of 10.4 per cent.
