The manager

Calculus Capital was founded by John Glencross and Susan McDonald in 1996; both are still actively involved. Calculus Capital is an experienced EIS and VCT fund manager and a pioneer in the tax efficient arena, having launched the UK’s first approved EIS fund in 1999/2000.

Investment strategy 

Calculus’s focus has always been the same: unlisted companies seeking development or scale-up capital that have:

  • A robust business model
  • A strong management team
  • Evidence of market opportunity
  • Potential, in the manager’s view, of achieving a target IRR of 20%

Most of the deals come to Calculus via corporate advisers.

Calculus aims to find and back capable management teams in companies that are already successfully selling products and services. Sectors of interest include agritech, leisure, telecoms, transportation, healthcare and business services. Once the VCT finds successful founders, it is likely to back them in their successive ventures.

Exit track record

Calculus Capital has achieved a number of exits over the years. A recent example is shown below. Please remember, past performance is not a guide to the future.

Synpronics – Calculus VCTSynpromics

Synpromics is a Scottish biotech company and the market leader in gene control therapeutics.

Its synthetic promoters are designed to improve gene regulation and precisely control protein production, therefore, creating better targeted gene therapies. Its technology has wide applications, including potentially treating conditions such as haemophilia, liver and heart disease.

Calculus Capital first invested in 2015 and then in 2017. The total investment was £5.6 million through its EIS and VCT. In August 2019, Synpromics was acquired by AskBio, the American pioneer in gene therapeutics, for an undisclosed amount, allowing the VCT to achieve a profitable exit. 

Portfolio overview

As of August 2019, the Calculus VCT holds investments in 29 qualifying companies across a wide range of sectors. The majority of the qualifying portfolio is held in unquoted companies and a small proportion in AIM-listed stocks. Three of the top four holdings of the enlarged portfolio are money market funds. As at 31 July 2019, 42.4% was held in Aberdeen Sterling Liquidity Fund, Goldman Sachs Sterling Liquidity Fund and Fidelity Sterling Liquidity Fund.

In the year to February 2019, the company made 10 new qualifying investments as well as two follow-on deals. The latest available portfolio breakdown is shown below, as at February 2019.

Examples of portfolio companies

Arecor – Calculus VCTArecor Limited

Arecor is a biopharmaceutical company that focuses on creating more effective formulations of pre-existing drugs. To do so, it has developed its own technology, Arestat, which significantly improves drug stability in liquid formats, preventing drug breakdown.

The company is currently working on treating diabetes, a disease that is estimated to affect close to 415 million people worldwide. Arecor has developed three proprietary versions of insulin and glucagon drugs for rapid treatment and more effective glycemic control. 

Aside from its own drug development, Arecor also partners with other pharmaceutical companies to reformulate and improve existing products.

Calculus led a £6 million funding round in September 2018 alongside Downing Ventures and Albion Capital. The investment will be used to fund clinical trials as well as drug development for other conditions.

WeedingTech – Earthworm EISWeedingtech

A cleantech company, Weedingtech treats weeds and moss using environmentally friendly hot foam, replacing the need for harmful herbicides.

The company has gained traction in recent years as governments and regulators have become increasingly concerned about the risks of relying on chemical herbicides. Just this year, France enforced a ban on weedkillers containing glyphosate, a potential carcinogen. Weedingtech has already been adopted by UK businesses like Yeo Valley Family Farms and South West Water and has expanded into countries across Europe and North America. 

Calculus invested £2.2 million in April 2019; the investment will be used to help support the company’s growth in North America.

Air Leisure Group Limited

As is to be expected, not all investments work out. Air Leisure Group operated and owned trampoline parks across Europe. The company opened its first site in Gloucester in October 2015 before expanding into Denmark with three new sites.

Unfortunately, due to difficult trading conditions the company went into administration in early 2019. The VCT had invested £200,000 in 2017, this was written down in full.

Performance and dividends

The VCT targets a regular annual dividend of 4.5% of NAV. Dividends are variable and not guaranteed. The dividend track record and annual performance data of the D share class is shown below. However, past performance is not a guide to the future.

Risks: important

This, like all investments available through Wealth Club, is only for experienced investors happy to make their own investment decisions without advice.

VCTs are high-risk so should only form part of a balanced portfolio and you should not invest money you cannot afford to lose. They also tend to be illiquid and hard to sell and value. Before you invest, please carefully read the Risks and Commitments and the offer documents to ensure you fully understand the risks. 

Tax rules can change and benefits depend on circumstances.

VCTs can now only invest new money in growth capital deals. Management buyouts, replacement capital deals and investments in mature companies are no longer permitted. This results in considerably higher risks.

Calculus Capital has an exclusive focus on EIS and VCT investments, both of which are subject to HMRC rules, which can change frequently. This could leave the firm and its investee companies vulnerable if rules change unfavourably in future.

  • Invest by 28 August 2020 for allotment in the 2020/21 tax year.

Dividend reinvestment scheme

There is a dividend reinvestment scheme which allows shareholders to reinvest future cash dividend payments in new shares, if desired. As these are new shares they should be eligible for tax relief (you will need to claim this on your tax return or directly with HMRC) and the shares will count towards the VCT annual subscription limit.

Share buyback policy

The board intends to buy back shares at a discount of no greater than 5% (or 10% in respect of buybacks made before 28 February 2020) to the most recently published net asset value per share. This is subject to availability and board and shareholder approval. 

Annual rebate when you invest through Wealth Club

The Calculus VCT offer includes an annual rebate for Wealth Club investors, payable for the first three years. This is a rebate of our renewal commission and should be equivalent to 0.10% of the Net Asset Value of the Offer Shares issued to you when you invest. You will find the terms and conditions for annual rebates within our Terms of Business.

Our view

With assets of around £15 million, this is one of the smallest established VCTs currently fundraising. It gives access to many of the investments also featured in the Calculus EIS fund, but with a much lower entry point – the minimum investment is for this VCT is £5,000.
