Interim Management Statement

1 November 2012

Henderson Group plc ('Henderson Group' or 'the Group') is publishing its second Interim Management Statement for 2012 today. The comments below refer to the period from 1 July 2012 to 30 September 2012 ('the period'), unless otherwise stated.

Key points

·; AUM up £1.2bn to £64.8bn at 30 September 2012.

·; Positive net flows into European retail and Property funds.

·; Strong investment performance over one and three years.

Commenting on the Interim Management Statement, Andrew Formica, Henderson Group's chief executive said: "I am encouraged by the strong investment performance across our clients' portfolios. Although investors remained cautious in their appetite for risk products, confidence improved during the period particularly about Europe and therefore outflows from our retail funds slowed compared to the second quarter. Our strict cost discipline allows us to continue to invest in the business and enhance the service we provide to our clients. This means that we are well positioned to benefit from any improvements in investor sentiment."

Investment performance

Henderson's investment performance across the majority of asset classes and product types has improved. Over one year, 70% and 92% (58% and 78%: 1H12) of Equity and Fixed Income funds respectively outperformed and 73% and 85% (66% and 98%: 1H12) over three years.

AUM and flows

Total AUM increased by £1.2bn during the period to £64.8bn due to favourable market and FX movements of £2.3bn offset by net outflows of £1.1bn.

Net retail outflows were £296m. This was predominantly driven by outflows from the UK OEIC range. We continue to experience outflows as clients and advisers reposition their portfolios in advance of the implementation of the Retail Distribution Review as well as having some core funds, notably in our multi manager range, underperforming. We are encouraged by the turnaround in our European SICAV range, which showed positive net flows in the period, driven by excellent investment performance, and in particular strong inflows into our award winning Henderson Horizon Euro Corporate Bond fund. We have also seen a more positive trend in our US Mutual fund range as we moved through the period.

Institutional net outflows, excluding Phoenix, were £585m during the period. Funding activity was particularly low during the period and hence there was little to offset against a range of previously notified outflows. In addition, the modest current year and one year returns on our absolute return fund range, combined with industry aversion to Europe and equity long short strategies, has led to an increase in both notified and actual redemptions. Performance improved over the period and, if maintained through the remainder of the year, then we should see an improvement in flows as we move into 2013.

Property had net inflows of £50m during the period as disposals were more than offset by £195m investment of client commitments over the period.

Balance sheet

The Group's balance sheet at 30 September 2012 shows total net assets of £730m (30 June 2012: £736.7m) including unrestricted cash and cash equivalents of £119.4m (30 June 2012: £87.8m). The net debt position has halved to £30.6m at 30 September 2012 (30 June 2012: £62.2m).

Board and Committee changes

As previously announced, Sarah Arkle has been appointed as a Non-Executive Director to the Henderson Group Board, effective from 5 September 2012. In addition, Sarah joined the Board Risk, Nomination and Remuneration Committees in October 2012.
