I certify to the following HIGH NET WORTH INVESTOR STATEMENT:
If you meet condition A or B below, you may choose to be classified as a high net worth individual for the purposes of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005.
- A) In the last financial year, you had annual income of £170,000 or more. Income does NOT include any one-off pension withdrawals.
- B) Net assets of £430,000 or more. Net assets do NOT include: your home (primary residence), any loan secured on it or any equity released from it, your pension (or pension withdrawals) or any rights under insurance contracts. Net assets are total assets minus any debts you owe.
I declare that I have answered yes to A and/or B and wish to be treated as a high net worth individual.
I understand this means: a) I can receive financial promotions where the contents may not comply with rules made by the Financial Conduct Authority (FCA); b) I can expect no protection from the FCA, the Financial Ombudsman Service or the Financial Services Compensation Scheme.
I am aware that it is open to me to seek advice from someone who specialises in advising on investments.
I accept that I could lose all of the money that I invest.
I confirm that I am an Independent Financial Advisor authorised and regulated by the Financial Conduct Authority.
I accept the terms and conditions.
If you meet condition A, B or C below you may choose to be classified as a self-certified sophisticated investor for the purposes of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005.
Have you:
- A) Worked in a professional capacity in the equity sector, or in the provision of finance for small and medium enterprises in the last two years?
- B) Been the director of a company with an annual turnover of at least £1.6 million, in the last two years?
- C) Been a member of a syndicate of business angels for more than six months, and are you still a member?
I declare that I have answered yes to A and/or B and/or C and wish to be treated as a self-certified sophisticated investor.
I understand that this means: a) I can receive financial promotions where the contents may not comply with rules made by the Financial Conduct Authority (FCA); b) I can expect no protection from the FCA, the Financial Ombudsman Service or the Financial Services Compensation Scheme.
I am aware that it is open to me to seek advice from someone who specialises in advising on investments.
I accept that I could lose all of the money that I invest.
I make this statement so that I can receive promotional communications relating to non-readily realisable securities as a restricted investor. I declare that I qualify as a restricted investor because:
- In the twelve months preceding today's date, I have not invested more than 10% of my net assets in non-readily realisable securities.
- I undertake that in the twelve months following today's date, I will not invest more than 10% of my net assets in non-readily realisable securities.
Net assets for these purposes do not include: the property which is my primary residence or any money raised through a loan secured on that property; any rights under a qualifying contract of insurance; any benefits (in the form of pensions or otherwise) payable on termination of service or on death or retirement; or any withdrawals from pension savings (except where used directly for income in retirement).
I accept that the investments to which the promotions will relate may expose me to a significant risk of losing all of the money or other property invested. I am aware that it is open to me to seek advice from an authorised person who specialises in advising on non-readily realisable securities.
I confirm that I am a Professional Client as defined by the Financial Conduct Authority. I accept the terms and conditions.
