T. Rowe Price Spectrum International Equity Fund

Supplement to Summary Prospectus Dated May 1, 2020, as supplemented

At a meeting held on February 10, 2021, the fund’s shareholders approved an amended and restated investment management agreement, which will result in changes to the fund’s overall expense structure, as described below.

The fund does not currently charge a management fee. However, the fund incurs acquired fund fees and expenses, which represent the fund’s proportionate share of the expenses of the underlying T. Rowe Price Funds in which it invests (Underlying Funds). In addition, the fund passes through its direct operating expenses to its Underlying Funds and the fund effectively does not directly pay any operating expenses.

On or about March 23, 2021, the fund will begin charging an all-inclusive management fee of 0.89% based on the fund’s average daily net assets. The all-inclusive management fee will cover investment management and all of the fund’s operating expenses except for interest; expenses related to borrowings, taxes, and brokerage; nonrecurring, extraordinary expenses; and any acquired fund fees and expenses.

The fund currently invests in the Investor Class of its Underlying Funds. Effective on the date that the fund begins charging an all-inclusive management fee, the fund will end the pass-through of its direct operating expenses to its Underlying Funds and will convert its Investor Class shares of each Underlying Fund to Z Class shares. Since T. Rowe Price is contractually obligated to waive and/or bear all of the Z Class’ expenses, with certain limited exceptions, the fund’s total acquired fund fees and expenses associated with investing in the Underlying Funds’ Z Classes are expected to be less than 0.01%.

Effective on the date that the fund implements these changes, which is expected to be March 23, 2021, the fee table and expense example are revised as follows:

Fees and Expenses of the Fund

Shareholder fees (fees paid directly from your investment)
Maximum account fee	$20	a
Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)
Management fees	0.89	%b
Distribution and service (12b-1) fees	—
Other expenses	—
Acquired fund fees and expenses	—	b
Total annual fund operating expenses	0.89	b

aSubject to certain exceptions, accounts with a balance of less than $10,000 are charged an annual $20 fee.

bRestated to reflect current fees.

Example This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 year	3 years	5 years	10 years
$91	$284	$493	$1,096

The date of this supplement is February 16, 2021.
