1 May 2013

Henderson Group plc ('Henderson Group' or 'the Group') is publishing its first Interim Management Statement for 2013 today. The comments below refer to the period from 1 January 2013 to 31 March 2013 ('the period'), unless otherwise stated.

Key points

·; AUM up £3.2bn to £68.9bn at 31 March 2013.

·; Strong net flows into our SICAV and US Mutual retail funds.

·; Consistently strong investment performance over one and three years.

·; Net cash increased to £31.9m (31 December 2012: £17.9m); balance sheet continues to strengthen.

Andrew Formica, Henderson Group's Chief Executive, said:

"I am pleased with the performance of our retail funds especially our SICAV funds which recorded strong positive net flows as investor sentiment improved over the quarter in both Europe and Asia. In addition, positive cash flows improved the Group's financial strength."

"I would also like to take this opportunity to welcome our new Chairman, Richard Gillingwater, and thank our out-going Chairman, Rupert Pennant-Rea, for his guidance and support."

Investment performance

Henderson's investment performance across asset class and product type is strong. Over one year, 77% and 84% (81% and 79%: FY12) of Equity and Fixed Income funds respectively outperformed and 68% and 82% (72% and 79%: FY12) over three years.

AUM by channel

AUM by asset type

AUM and flows

Total AUM increased by £3.2bn during the period to £68.9bn due to favourable market and FX movements of £4.5bn offset by net outflows of £1.3bn.

Net Retail inflows were £188m. This is the first quarter of positive growth since Q1 2011 and is an encouraging result since it includes outflows of £400m from the previously announced loss of two investment trust mandates, but does not capture the win of a new investment trust mandate (Henderson Value Trust, with £143m of assets under management), which transferred to us on 1st April 2013. Our European SICAVs range had strong net inflows of £480m across the European Corporate Bond, Global Technology and Global Property Equities funds. Our US Mutual fund range also experienced good net inflows, in particular into the Global Equity Income fund which was our best performing fund in that range in terms of inflows.

Net Absolute Return inflows were £36m for the period. We are encouraged by the continued improvement in investment performance since Q2 2012 which has been sustained into Q1 2013 and there are early signs of an improving demand environment for such products.

Net Institutional outflows, excluding Phoenix, were £1.2bn during the period of which £840m was due to one ex-Gartmore client exiting from a global equity mandate and an outflow of £331m in Property primarily due to the winding up of a 10-year old fund as the fund reached the end of its life. Overall, our current pipeline for institutional business is positive, with notable wins in credit, and is expected to fund in Q2 2013. In addition, we have a large pipeline of uninvested client commitments totalling £1.1bn in Property.

90 West Asset Management

Henderson has acquired a 33% interest in 90 West Asset Management, an Australian-based global natural resources investment management firm. In addition to acquiring this equity position, Henderson and 90 West have entered into an exclusive global distribution agreement.

The acquisition follows the hire late last year of a US credit specialist team based in Philadelphia and the acquisition of a 50% interest in Northern Pines Capital a US long short hedge fund. These transactions support our strategy of diversifying our business outside the UK and Europe.

Gartmore pension scheme

In April 2012 the Trustee of the Gartmore Pension Scheme (the Scheme) entered into a buy-in agreement with Pension Insurance Corporation (PIC) and has now commenced winding up the Scheme as part of the arrangement with PIC. This will remove any residual risk to the Group.

Balance sheet and cash position

The Group's balance sheet at 31 March 2013 shows total net assets of £817.2m (31 December 2012: £781.2m) including unrestricted cash and cash equivalents of £181.9m (31 December 2012: £167.9m). The net cash position is £31.9m at 31 March 2013 (31 December 2012: £17.9m).

A final dividend for 2012 of 5.05 pence per share, totalling approximately £56.3m, will be paid on 31 May 2013 subject to approval at the AGM on 1 May 2013.

2013 interim results

The Group intends to release its 2013 interim results on 8 August 2013.
