Risk factors
An investment in the Puma AIM Inheritance Tax Service may not be suitable for all investors.
An investment in the Service carries risk and you should take your own independent advice. You should only invest in the Service on the basis of the Investment Overview and Investor Agreement which details the risks of the investment. Below are the key risks of the Service:
Tax reliefs are not guaranteed: Tax rules may change, which could affect the reliefs available for IHT purposes. Tax reliefs are subject to an individual’s personal circumstances and independent tax advice should be taken. While the Tax Adviser will also carry out an annual review of the portfolio, we can’t guarantee that all portfolio investments will qualify for BR. If a company should be non-qualifying at the time of being selected for the portfolio or become non-qualifying thereafter, then any applicable BR could be reduced accordingly.
Long-Term investment: An investment in the Puma AIM Inheritance Tax Service should be considered a long-term investment.
Capital at risk: The value of investments can go down as well as up, so investors may not receive their full amount invested. An investment in smaller companies is likely to be higher risk than many other investments. Companies quoted on AIM are likely to be more risky and have less rigorous listing requirements than companies quoted on the main list of the London Stock Exchange. Dealing costs may be significant, particularly in respect of a relatively small investment in the Service.
Past performance: The past performance of the Puma AIM Inheritance Tax Service, Puma Investments, the funds Puma Investments manages or the companies it advises, is not a reliable indicator of future performance. Future performance may be materially different from past results. There is no guarantee that can be given as to the overall performance or level of return that can be achieved from investments made, or that the objectives of the Service will be achieved.
Potentially illiquid investment: AIM stocks are largely small and illiquid. They are characterised by significant spreads and low trading volumes. A sale of such shares may be difficult, slow and only achievable at lower than indicated market price.
