Final answer:
The shareholder (SH) at record date determines who is eligible to vote. Quorum is the minimum required attendees for a valid voting session, proxy in writing allows shareholders not present to vote through an appointee, and a voting pool or trust consolidates voting power among shareholders.
Step-by-step explanation:
The significance of shareholder (SH) at record date in relation to quorum, proxy in writing, and voting pool or trust is multifaceted. Firstly, 1) SH at record date determines the eligibility to vote; only those shareholders listed on the record date are entitled to vote at the shareholders' meeting. Secondly, 2) Quorum refers to the minimum number of shareholders that must be present, either in person or by proxy, for the meeting to be legally valid and for votes to be carried out. Thirdly, 3) Proxy in writing is an authorization allowing shareholders who cannot attend the meeting to appoint another person to vote on their behalf. Lastly, 4) Voting pool or trust refers to an agreement between shareholders to combine their voting power, usually in an effort to strengthen their position on certain matters or to ensure a more unified decision-making process.
