Explanation
A custodian in mutual fund is a trust company, bank, or similar financial institution that is responsible for holding and safeguarding the securities owned within a mutual fund. The custodian also records and reports all transactions to the fund manager. The custodian does not oversee the general administration, construct and manage the portfolio, or calculate the NAVPU of the mutual fund. These are the roles of other entities such as the fund administrator, the fund manager, and the fund accountant.

Explanation
A LIF is a type of registered retirement income fund that is used to hold and pay out locked-in pension funds.
A LIF has both a minimum and a maximum withdrawal limit for each calendar year, which are determined by the federal or provincial pension legislation, the age of the annuitant, and the value of the fund. The minimum withdrawal limit is similar to that of a RRIF, but the maximum withdrawal limit is intended to ensure that the LIF provides income for the lifetime of the annuitant123 References = Canadian Investment Funds Course (CIFC) - Module 3: Registered Plans - Section 3.4: Life Income Fund (LIF)4 and web search results from search_web(query="maximum withdrawal limit for LIF RRSP RRIF DPSP")123

Explanation
A mutual fund trust is a type of unit trust that meets certain conditions under the Canadian Income Tax Act and is eligible for favourable tax treatment. A unit trust is a collective investment vehicle that holds assets and distributes profits to individual unit owners, also called unitholders, instead of reinvesting them in the fund. A mutual fund trust is not a corporation and does not have a board of directors or shareholders. It is also not a closed-end fund, which has a fixed number of shares that trade on an exchange. A mutual fund trust is an open-end fund, which can issue and redeem units at any time based on the net asset value of the fund.

Explanation
An eligible dividend is a type of dividend that is paid by a Canadian corporation that meets certain criteria and is eligible for the enhanced dividend tax credit. The dividend tax credit reduces the amount of tax payable on dividends by providing a credit against the tax liability. An eligible dividend has a higher gross-up rate and a higher dividend tax credit rate than a non-eligible dividend, which means that it results in a lower effective tax rate. A capital dividend is a type of dividend that is paid from the capital gains realized by a corporation and is tax-free to the shareholder. However, a tactical asset allocation fund is unlikely to pay capital dividends, as they are usually reserved for private corporations. A capital gain is the profit from selling an asset at a higher price than its purchase price. Only 50% of the capital gain is taxable, which means that it has a lower effective tax rate than interest income, which is fully taxable. However, a capital gain distribution from a mutual fund is not the same as a capital gain from selling the mutual fund units. A capital gain distribution is paid when the fund realizes a capital gain from selling its underlying assets, and it is taxable in the year it is received, regardless of whether the shareholder sells the fund units or not. Therefore, it does not benefit from the deferral of tax that occurs when the shareholder sells the fund units at a later date. An interest distribution is paid when the fund earns interest income from its underlying assets, such as bonds or money market instruments. Interest income is fully taxable at the marginal tax rate, which means that it has the highest effective tax rate among the four types of distributions.
To compare the amount of tax payable for each type of distribution, we can use the following formula:
Tax=(Distribution×Grossup)×MarginalTaxRate(Distribution×Grossup)×DividendTaxCreditRate For simplicity, we assume that Davis receives $100 of each type of distribution and that he does not have any other income or deductions. We also ignore any provincial taxes or credits. Using the formula, we can calculate the tax payable for each type of distribution as follows:
Capital Dividend: Tax=(100×0)×0.26(100×0)×0=0
Capital Gain: Tax=(100×0.5)×0.26(100×0.5)×0=13
Eligible Dividend: Tax=(100×1.38)×0.26(100×1.38)×0.15=10.14
Interest: Tax=(100×1)×0.26(100×1)×0=26
Therefore, an eligible dividend would result in the lowest amount of tax payable, followed by a capital gain, a capital dividend, and an interest distribution.
