Shareholders of record of the Company's common stock will receive an Internal Revenue Service Form 1099-DIV from Computershare, the Company's 2021 distribution paying agent. If shares were held in "street name" during 2021, the IRS form will be provided by a bank, brokerage firm, or nominee. Because the Company's tax return has not yet been filed for the year ended December 31, 2021, the distribution allocations presented herein have been calculated using the best available information to date.

The tax treatment of these distributions by state and local authorities varies and may not be the same as the IRS's treatment. Because federal and state tax laws affect individuals differently, the Company cannot advise shareholders on how distributions should be reported on their tax returns. The Company encourages shareholders to consult with their own tax advisors with respect to the federal, state and local income tax consequences of these distributions.
