Downing AIM Estate Planning Service ISA

The Downing AIM IHT ISA portfolio aims to make long-term investments into smaller, often unloved, AIM-quoted businesses available at what Downing considers to be an attractive valuation. The team frequently buys material minority shareholdings and looks to exert some influence over the management to help turn the business around and boost share value. This is an active hands-on approach, which is rare when investing in AIM-quoted companies. 

The £100 million AIM IHT portfolio is run by Downing Fund Managers, the boutique investment arm of Downing LLP, which manages a total of £581 million (March 2023) across a range of investment funds, all broadly following the same investment philosophy. 

The portfolio offers built-in downside protection insurance for at least the first two years, designed to cover the first 20% of losses on the net initial investment on death, for investors below the age of 90. There is also optional life cover for investors under the age of 85 at the time of investment.

Investment strategy

The team aims to invest in companies when it believes they are undervalued and there is a catalyst for the company to recover. Companies often become undervalued when there is a perception something is wrong with them, which prevents investors from taking a closer look, causing, in turn, the shares to trade cheaply. For this reason, value investing is not for the fainthearted as some companies in this category may be in financial distress. 

The team takes it one step further, looking to buy a material minority shareholding so as to be able to influence the company management. This can involve working with other institutional shareholders to appoint a new management team with a new strategy, sell off non-core assets, restructure the business, or put in place long-term incentive plans. 

This strategy is applied across all the funds the team manages. Companies in the AIM IHT ISA portfolio will vary in size but will have a market capitalisation of no more than £500 million at the time of the initial investment. 

Current portfolio overview

The portfolio currently contains approximately 30 companies, spread across a variety of sectors and the market cap spectrum. There is a skew towards industrial support services and software & computer services, which together account for 37.4% of the portfolio. 

The service has a bias towards smaller AIM stocks, approximately 70% of the portfolio is currently invested in businesses valued at £250 million or less. The service has limited exposure (6.3%) to AIM stocks valued in excess of £500 million (March 2023). The average market cap of the portfolio is £244.2 million.

Examples of portfolio companies

Volex – Downing AIM IHTVolex

Volex is a global supplier of power cords and cable assembly solutions, providing either contract manufacturing or product development services. 

Volex is an example of a turnaround situation favoured by Downing. Before investing, the business had undergone several years of chronic underperformance. The share price had fallen from £3.77 in 2010, to just 28p in 2016. Downing believed Volex had lost its way under the direction of a succession of weak boards following multiple changes in both management and strategy resulting in the company becoming unfocused and mismanaged. 

In 2015, Nat Rothschild bought a 25% stake in the business and appointed himself Executive Chairman. He introduced several changes, including cutting loss-making contracts, rationalising the cost base, seeking new markets, and rolling out an acquisition strategy to consolidate smaller cable assembly businesses. Whilst other Downing investment mandates invested in Volex at an earlier (and riskier) stage of this transition, the IHT service backed the company during a fundraising at 75p per share in 2018. In the four years since, Volex has increased its operating profits by 367% to $41 million and grown its revenue by almost $300 million. In a full year trading update in April 2023, it announced another year of strong growth with both revenue and operating profit ahead of market expectations. Please note, past performance is not a guide to the future. 

Volex currently has a market cap of £451.1 million (June 2023).

Ramsdens-Downing-AIM-ISA.jpgRamsdens Holdings

In addition to the team’s strategic investments in companies undergoing some form of turnaround, Downing also looks to back what it views as attractively valued more mature businesses which could provide some ballast to the portfolio. An example is Ramsdens Holdings (“Ramsdens”). 

The company was founded in Stockton-on-Tees in the 1970s with its first store opening in 1987. Today, it has 158 stores and a workforce of over 700.

Ramsdens operates across four segments: foreign currency exchange, pawnbroking loans, jewellery retail, and precious metal purchasing. The business’s strategy revolves on increasing its footprint in the UK through a branch-based model as well as developing an online proposition for jewellery sales.

In its latest financial year (to September 2022), the company reported revenues of £66.1 million, up from £40.7 million in 2021. Profit before tax also rose in the period to £8.3 million, up from £0.6 million in the prior year as the business recovered from difficult trading conditions during the pandemic. Ramsdens attributed its recent performance to its diversified revenue streams with all four segments delivering strong results and foreign currency profit rebounding as international travel returned. Past performance is not a guide to the future.

The current market cap of the business is £77.7 million (June 2023).

Alliance Pharma 

As is to be expected, not all investments work out. Alliance Pharma (“Alliance”) is an example. 

Alliance is an international healthcare group which specialises in marketing healthcare and pharmaceutical products. The Group has a large portfolio of consumer brands and prescription medicines which it sources through acquisitions or licensing deals. 

In 2022, the Group’s share price declined sharply on the back of disappointing half-year results and a fine from the Competition & Markets Authority (CMA) amid an ongoing investigation. These factors, plus concern over a potential acquisition, led Downing to remove the position from its model in August 2022 and sell down the holding across all client accounts.


The Downing AIM IHT Service was launched in March 2014. The chart below shows performance over five years compared with other AIM IHT portfolios available through Wealth Club. 

The track record prior to December 2019 is based on the return of first investor’s portfolio in the Downing AIM Estate Planning Service and the Downing AIM ISA Service, net of fees. From December 2019 onwards, all investors’ performance across both products have been consolidated, on a net of fee basis. 

Like other IHT portfolios, this is a discretionary managed service so each portfolio is likely to be different.

Downside protection cover and optional life cover 

Investors in the Downing AIM IHT ISA service can benefit at no extra cost from a downside protection policy underwritten by an A-rated insurance provider.

Key details of the downside protection cover are:

  • The policy is designed to cover a loss in value of up to 20% of net initial investment, after fees, for at least two years
  • Cover is for all subscribers under the age of 90 at death
  • There are no exclusions for pre-existing medical conditions
  • There are no medical questionnaires
  • There is no additional cost to investors: the premium is paid by Downing

There is also a separate and optional life cover policy for the first two years, which effectively makes the portfolio IHT free from day one. The policy is designed to pay 40% of the gross subscription (including all fees) in the event of death within the first two years. Investors opting for the life cover policy will only start benefiting from the downside protection cover after two years. Investors must be under age 85 at the time of making investment to qualify. 

Terms and conditions apply, and some exclusions also apply to the life cover option: please read the provider documents carefully.

Access to your investment

Investments in this portfolio are for the long term. However, if your circumstances change, you can sell some or all of your shares, although sometimes this can take a while depending on market conditions and liquidity. Partial withdrawals are subject to a minimum remaining portfolio value of £15,000. In normal market conditions, Downing aims to fulfil withdrawal requests within 15 working days but this is not guaranteed. For large withdrawal requests, Downing reserves the right to take longer as it may be required to ensure the orderly disposal of investments. Any amount you withdraw will no longer be IHT free. Withdrawals may result in a Capital Gains Tax liability unless held in an ISA. 

Risks – important

This, like all investments available through Wealth Club, is only for experienced investors happy to make their own investment decisions without advice. Those considering AIM Inheritance Tax Portfolios should be comfortable with the significant risks of investing on AIM.

AIM IHT portfolios should only form part of a balanced portfolio. Your capital is at risk and you should not invest money you cannot afford to lose. If a service is managed by a small investment team, it could create key person risk. The fewer the companies included in the portfolio, the higher the risk of loss if things don’t go to plan. 

AIM stocks can be hard to sell, particularly at the smaller end of the market, and can be illiquid. AIM shares can be very volatile especially if the market falls sharply. The difference between the buying and selling price (spread) of AIM shares is often wider than the spread for shares listed on the main market. 

Eligibility for BPR, based on current rules, is assessed at the date of death and will depend on the companies in the portfolio remaining qualifying. Broadly speaking, you will need to have held a BPR qualifying stock for at least two years and still hold it on death to qualify. Tax rules can change and benefits depend on circumstances.

Before you invest, please carefully read the Risks and Commitments and the offer documents to ensure you fully understand the risks.

Our view

The Downing AIM ISA comes with an innovative downside protection policy at no additional cost to investors. It aims to cover a loss in value of up to 20% of the net initial investment for at least two years, if they die before the age of 90. The policy could be appealing as it reduces some of the risks of investing in AIM.

Another point of interest is the optional life cover for the first two years (an additional premium applies for this).

Judith MacKenzie is a highly regarded fund manager with more than two decades of experience investing in smaller companies. 

The focus on smaller, and often unloved companies may bring diversification to existing portfolios of larger and more popular AIM stocks. 

The portfolio’s fees are higher than some of its peers. The minimum of £20,000 could make it a contender for this year’s ISA subscription.
