How is Britam Money Market Fund interest calculated and taxed?

For liquid, low-risk savings it is competitive: around 8.3% net with next-day access beats the 3–4% on a bank savings account. It is regulated by the Capital Markets Authority, with assets held by an independent custodian. It is not capital-guaranteed and not covered by KDIC deposit insurance.
