We have written to investors in class "I" shares of the Henderson Multi-Manager Manged Fund. This is to advise them that we are changing the name of the share class from class "I" to class "B".

We are proposing to merge the Henderson Global Bond Fund into the Henderson Overseas Bond Fund (the host fund). If the merger is approved by investors in the Henderson Global Bond Fund the merger will take place on 25 October 2012. Investors in the Henderson Overseas Bond Fund are not required to vote on the merger because there is no material impact on their investment. It will, however, be necessary to suspend dealing on the Henderson Overseas Bond Fund whilst the merger is undertaken. Dealing in the Henderson Overseas Bond Fund will be suspended immediately after the valuation point on Thursday 25 October and normal dealing will resume on Monday 29 October 2012. Sample letters relating to the dealing suspension can be found below.

We are proposing to merge two funds in September 2012. This involves merging funds that have historically had a high institutional investor base into similar funds we manage. Since there are some retail investors in the Gartmore Long Term Balanced Fund, which is proposed to merge with the Henderson Diversified Growth Fund, the necessary sample letters and circulars can be found below. For the proposed merger of the Henderson UK Equity Income Trust with the Henderson UK Equity Income Fund, retail investors are only affected by the temporary dealing suspension on the Henderson UK Equity Income Fund as there are no direct retail investors in the Henderson Equity Income Trust. Sample letters relating to the dealing suspension for host funds can be found below. In addition, we are terminating the Henderson Japan Absolute Return Fund. The necessary circular and accompanying sample letters can also be found below.

Earlier this year we announced that we would be undertaking some further rationalisation of our UK-domiciled fund range. In July 2012 we will be undertaking the second phase of this programme. This involves four funds being merged into host funds. Full details of the proposals can be found in the relevant documents below.

The KIID is a pre-contractual information document which will replace the Simplified Prospectus and must be in place by 1 July 2012. We will replace the Simplified Prospectus for Henderson funds on 18 June 2012. This communication is relevant to intermediaries involved in or intending to recommend all UCITS funds under the Henderson UK fund range.
