Capital Stock

17.  CAPITAL STOCK

Authorized capital stock consists of 25 million preferred shares with a par value of $1 per share, none of which was outstanding at 30 September 2011, and 300 million shares of common stock with a par value of $1 per share.

In 2007, the Board of Directors authorized the repurchase of up to $1,000 of our outstanding common stock. We repurchase shares pursuant to Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended, through repurchase agreements established with several brokers. During fiscal year 2011, we purchased 7.4 million of our outstanding shares at a cost of $649.2, which completed our 2007 $1,000 share repurchase program.

On 15 September 2011, the Board of Directors authorized a new $1,000 share repurchase program. At 30 September 2011, $1,000 in share repurchase authorization remains.
