<p><strong>Risk summary.</strong> This is a high risk investment. You could lose all the money you invest and you are unlikely to be protected if something goes wrong. Investments are illiquid compared with cash savings and returns are not guaranteed. Past performance is not a reliable indicator of future results. Do not invest more than you can afford to lose. If you are unsure whether investing is right for you, seek independent financial advice.</p>

| Backed by a physical asset | Yes, real UK property | No | No |
| Shariah compliant | Independent Shariah board | Usually | Rarely |
| Daily market swings | Not traded on stock markets | Yes | No |

Difference:
Illustrative only, based on an assumed rate of 4% a year for illustration purposes. The bank figure assumes your money sits still with no growth.

FAQs
Straight answers.
What do I actually own with Amana?
Amana is an indirect investment. You do not buy or own property directly. Your money is invested through Amana into real UK property, and any returns are paid to you as dividends.
Is Amana regulated by the FCA?
Amana by Bayuti is a trading name of Elite Capital and Management Services Limited, which is regulated by the Financial Conduct Authority (FRN 822039).
How is Amana Shariah compliant?
The product is structured to be Shariah compliant and is overseen by an independent Shariah board. Any returns come as dividends funded by property income, never from interest, so there is no riba at any point.
How do returns work?
Any returns are paid as dividends, funded by the income the underlying properties generate. Dividends are not guaranteed and the value of your investment can go down as well as up.
How much do I need to start?
You can start from £50.

Withdrawals below £50,000 are typically processed within 3 working days. Withdrawals of £50,000 or above are processed within 30 calendar days.
