[1] * Performance for the 5 Years and 10 Years period has been adjusted to align with the Fund’s audited Financial Highlights for the fiscal year ended December 31, 2021, which reflect the correction of an expense accrual. If performance had been calculated based on the net asset value (“NAV”) per share as of December 31, 2021 without the expense accrual adjustment, performance would have been higher.
