| ü |     | FOR the Advisory Approval of our Executive Compensation                                                                        |

#### Quorum Required
The presence at the Annual Meeting, via live webcast or by proxy, of holders of Common Shares entitled to cast a majority of all the votes entitled to be cast on any matter to be considered at the Annual Meeting or at any postponement or adjournment thereof shall constitute a quorum. Abstentions and broker non-votes are each included in the determination of the number of shares present at the Annual Meeting for the purpose of determining whether a quorum is present.

A broker non-vote occurs when an intermediary holding shares for a beneficial owner delivers a properly-executed proxy but does not vote on a particular proposal because the intermediary does not have discretionary voting power for that particular matter and has not received instructions from the beneficial owner.

#### Vote Required
If a quorum is present, then the affirmative vote required to approve the proposals described in this Proxy Statement are as follows:

| Proposal                                                                           |     | Vote Required                                                            |
| Election of a Trustee                                                              |     | A majority of votes cast for and against the election of such nominee(1) |
| Ratification of KPMG as our Independent Registered Public Accounting Firm for 2025 |     | A majority of votes cast on the proposal                                 |

The vote on compensation is advisory and not binding on our Board. However, our Board and CNCG Committee value all shareholder feedback and will continue to consider the outcome of the vote in reviewing executive compensation each year.
