CALGARY, ALBERTA--(Marketwired - May 17, 2013) - ATCO Ltd. announced today that its Board of Directors has approved a two-for-one share split of the outstanding Class I Non-Voting Shares and Class II Voting Shares. The two-for-one share split will take the form of a share dividend whereby share owners will receive one Class I Share for each Class I Share held and one Class II Share for each Class II Share held.

The record date will be June 13, 2013 and the payment date will be June 14, 2013. Ex-distribution trading in the shares on a split-adjusted basis will commence on June 17, 2013.

The Toronto Stock Exchange has determined to implement due bill trading in connection with the share split. A due bill is an entitlement attached to listed securities undergoing a material corporate action, such as a share split. In this instance, the entitlement is to the share dividend. The Class I Shares and Class II Shares will trade on a due bill basis from June 11, 2013 to June 14, 2013 inclusive. Any trades that are executed during this period will be flagged to ensure purchasers receive the entitlement to the share dividend. The due bill redemption date will be June 19, 2013.

Share owners do not need to take any action. Share certificates representing the additional Class I Shares and Class II Shares will be mailed to registered share owners after June 14, 2013. Existing share certificates should be retained by the share owners and should not be sent to ATCO or its transfer agent, CIBC Mellon Trust Company. Share owners with Class I Shares and Class II Shares held through a brokerage account will have their accounts automatically updated to reflect the share split.

No income tax will be payable by Canadian residents in respect of the share splits, and the share splits will not dilute share owners' equity. All share and per share data for future periods will reflect the share splits.

ATCO is undertaking the share splits to make the Class I Shares and Class II Shares more readily accessible to individual share owners, increase and broaden its share owner base, and improve the liquidity of the market for the shares.
