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 to turn the business around and boost value in the shares. This is an active hands-on investment approach, which is rare when investing in AIM-quoted companies. 

The £100 million AIM IHT portfolio is run by the Downing public equity team, which manages a total of £400 million (February 2022) across a range of investment funds, all broadly following the same investment philosophy. The AIM IHT ISA portfolio is, however, more diversified, with additional exposure to larger and more mature businesses which should help mitigate risk. 

In addition, investors can benefit from 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.

Important: The information on this website is for experienced investors. It is not a personal recommendation to invest. If you’re unsure, please seek advice. Investments are for the long term. They are high risk and illiquid and can fall as well as rise in value: you could lose all the money you invest.

The manager

Downing LLP was founded in 1986 and is a specialist investment management business with a focus on tax efficient investments. Today, the business has over 25,000 clients who collectively have over £1.5 billion invested with Downing. 

The public equity team is headed by Judith MacKenzie, Partner and Head of Public Equity. She has 20 years’ experience investing in small UK businesses. Judith is supported by three fund managers and an investment analyst. Together they manage £333 million across a number of UK equity investment mandates, £81 million of which the Downing AIM IHT & ISA service.

Downing LLP is the portfolio Discretionary Investment Manager, responsible for the day-to-day management of investor portfolios. The Custodian is IBP Markets Ltd, holding shares on investors’ behalf. The downside protection and life cover is provided by an A rated insurer.

Investment strategy

The Downing public equity 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 value investing one step further. It looks to buy a material minority shareholding so as to be able to influence the company management with the aim of unlocking potential value in the company. 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. However, to temper the risks the strategy entails, the AIM IHT ISA portfolio includes some larger, more mature companies. 

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 and computer services, which together account for 34.3% of the portfolio. 

The service has a bias towards smaller AIM stocks, approximately 40% of the portfolio is currently invested in businesses valued at £250 million or less. The service has minimal exposure to AIM stocks valued in excess of £1 billion (December 2021).

Examples of portfolio companies

Volex – Downing AIM IHTVolex Plc

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 three years since, Volex has increased its operating profits by 250% to $30 million and grown its revenue by more than $100 million , Volex's recovery appears to be underway (not guaranteed). The share price was 344.50p as at 31 December 2021. Please not, past performance is not a guide to the future.

Volex Plc is currently the largest holding within the AIM IHT ISA portfolio.

James Latham – Downing AIM IHTJames Latham Plc

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 James Latham Plc. The company dates back to 1756 and is one of the UK’s leading distributors of timber products. The business operates from 12 locations across the UK and Ireland. In its latest full-year accounts to March 2021, the business made operating profits of £19 million on revenues of £250 million, earnings per share has grown from 56p to 75.4p over the previous five financial years, against a share price of £12.80 (31 December 2021). Past performance is not a guide to the future.  

Northbridge Industrial Services Plc 

As is to be expected, not all investments work out. Northbridge Industrial Services Plc is an example. Northbridge is a provider of specialist industrial equipment and power sources to extreme environments across the globe. Past projects have included supplying power to oil fields and the Olympics. The business had previously been an acquisition vehicle and Downing liked its diversified nature. However, the business suffered following the downturn in oil & gas markets, as it became apparent it had more exposure to oil and gas than the company’s management team had initially believed. Downing sold its stake in the business, realising a 40-50% loss for investors. The downturn subsequently led to a series of profit warnings, and further share price declines for investors.


Growing investor confidence in backing out of favour AIM companies saw Downing’s investment strategy make a swift return to favour in 2021, boosting its longer-term track record, which has endured several years of poor investor sentiment.

Access to your investment  

Investors can request partial or full withdrawals from the portfolio at any time, subject to liquidity. In normal market conditions, Downing aims to fulfil withdrawal requests within ten working days but this is not guaranteed. For withdrawal requests greater than £30,000 Downing reserves the right to take longer as it may be required to ensure the orderly disposal of investments. 

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. 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. 

There is considerable key person risk as Judith MacKenzie is central to the service.

Our view

There are a number of interesting aspects to this AIM IHT ISA service. Firstly, it comes with a downside protection policy at no additional cost to investors. This is designed to cover a loss in value of up to 20% of the net initial investment for at least two years, provided the investor is under age 90 at death. The policy reduces some of the risks of investing in AIM, which might be appealing to some investors. 

The service also benefits from a high-quality investment team. Judith MacKenzie is a highly regarded fund manager with two decades of experience investing in smaller companies. The team’s sole focus is investing in UK smaller companies.  Past performance however is not a guide to the future. 

The focus on smaller, and often unloved companies may bring diversification to existing portfolios of larger and more popular AIM stocks. For investors considering investing smaller sums into an AIM IHT service this year, the Wealth Club minimum of £20,000 could be attractive.
