The Saudi Capital Markets Authority has 
approved an approximate 41% reduction in the paid of capital of 
Kingdom Holding Company subject to approval by shareholders at an  Extraordinary General Meeting.  Securing shareholder approval won't be a problem as Amir AlWaleed owns 95% of KHC.
The proposal is to reduce the number of shares from 6,300,000,000 to 3,705,882,300 and the capital from SAR 63,000,000,000 (US$16,8 billion) to SAR 37,058,823,000 (US$9.9 billion).
As per 
information at the Saudi Stock Exchange, KHC's shareholders' equity has decreased from SAR51.2 billion (US$13.7 billion) at 31 December 2008 to SAR22.3 billion (US$5.9 billion) at 30 September 2009.
A bit of hopefully informed speculation:  The reduction is an accounting exercise designed to eliminate negative retained earnings.  KHC will move roughly SAR 26 billion from the paid in capital account to the retained earnings account.   The transaction has no economic effect.  It is designed to have a legal effect.
Why would KHC want or need  to do this?
While I don't know the corporate law in Saudi, I assume that there are restrictions on the payment of dividends by companies with negative retained earnings.  As well, it could be a matter of optics.  It's hard to sell shares in a company with negative retained earnings - the growth story is less believable.
