Sean's distribution is reinvested at a NAVPU of $19.75 and he receives approximately 31.65 additional units.
When a mutual fund declares a distribution, it reduces its NAVPU by the amount of the distribution per unit.
In this case, the NAVPU drops from $21 to $19.75 after the distribution of $1.25 per unit. Sean's distribution is $625 ($1.25 x 500 units), which he reinvests in the mutual fund at the new NAVPU of $19.75. He receives

additional units. The total value of Sean's mutual fund holdings after the distribution and reinvestment is (500+31.65)×19.75=$10,500
, not $9,875. The NAVPU of the mutual fund does change after the distribution, regardless of whether Sean reinvests his distribution or not. References: [Unit 7: Mutual Funds Administration]

A Registered Education Savings Plan (RESP) is a tax-advantaged savings plan that helps parents and family members save for a child's post-secondary education. The government also contributes to the plan through the Canada Education Savings Grant (CESG) and the Canada Learning Bond (CLB), depending on the family income and the amount of contributions. However, there are some rules and limits that apply to RESP contributions and government grants. One of them is the lifetime contribution limit, which is the maximum amount that can be contributed to an RESP for a beneficiary from all sources. The lifetime contribution limit is $50,000 per beneficiary, regardless of how many RESPs are opened for them or who contributes to them.
Therefore, statement A is correct. Justin and Yvonne may contribute a combined lifetime maximum of
$50,000 for Grace to their RESP.
The other statements are incorrect for the following reasons:
* Statement B: RESPs are not tax-free investment plans. They are tax-deferred plans, meaning that the contributions are made with after-tax dollars and the investment income earned in the plan is not taxed until it is withdrawn as an educational assistance payment (EAP) for the beneficiary. The EAPs are taxed in the hands of the beneficiary, who usually has little or no income and pays little or no tax.
* Statement C: There is no annual contribution limit for RESP contributions. However, there is an annual limit for the CESG, which is 20% of the first $2,500 contributed per beneficiary per year, up to a maximum of $500 per year. The CESG also has a lifetime limit of $7,200 per beneficiary.
* Statement D: Contributions made to an RESP are not eligible for a tax deduction in the year they are contributed. They are made with after-tax dollars and do not reduce the contributor's taxable income.

Defined benefit pension plans base retirement income on formulas that may use:
Career average earnings # lower protection against inflation.
Final average earnings (last few years of salary) # better protection against inflation, since the calculation reflects recent, higher earnings that have already adjusted for inflation.
Defined contribution and group RRSPs do not guarantee inflation-adjusted benefits.
Thus, the Final average pension plan offers better inflation protection before retirement.

The independent review committee approves actions involving conflicts of interest only if they achieve a fair and reasonable result for the fund. The feedback from the document states:
"The Independent Review Committee will only approve actions where a conflict of interest arises if certain requirements are met, including, most importantly, the action achieves a fair and reasonable result for the fund."

A life income fund (LIF) is a type of registered retirement income fund (RRIF) that can be used to hold locked-in pension funds as well as other assets for an eventual payout as retirement income. A LIF cannot be withdrawn in a lump sum and has minimum and maximum withdrawal amounts each year. A LIF can only be funded by transferring money from a locked-in retirement account (LIRA) or another LIF. Therefore, D is the correct answer.
