Sale of small shareholdings

March 2012

On 14 March 2012 Henderson Group plc (Henderson Group) offered a free share sale facility (Facility) to eligible shareholders with shares valued at less than A$500 or the equivalent (called an unmarketable parcel).

Due to the proportionately higher brokerage costs that may otherwise be faced in selling the shares and the expense to Henderson Group of administering small shareholdings, we took the opportunity to encourage eligible shareholders to sell their existing shareholding through the Facility.

Eligible shareholders were identified based on shareholdings at close of business on 9 March 2012. The share price used to determine whether holdings qualified as an unmarketable parcel was the closing price of Henderson Group CHESS Depositary Interests (CDIs) on the ASX on 9 March 2012 of A$1.75 per share. The closing price of Henderson Group ordinary shares on the LSE on 9 March 2012 was 115.80 pence per share.

Following expiry of the notice period, 2,173,732 shares were sold under the Facility on behalf of 17,320 participating shareholders. The average price obtained was 121.1099 pence per share.

Holders of CDIs listed on the ASX received payment in Australian or New Zealand dollars, according to the holder's previous instructions, at A$1.883743 or NZ$2.390121 per share respectively.

Payments to participating shareholders were despatched on 11 May 2012.
