Common shares provide voting rights to the shareholders which provide the shareholders the ability to participate in major corporate decisions such as election of directors, mergers and acquisitions, selection of auditors, etc. When electing the members of the board of directors, there are two commonly used methods of voting: Statutory Voting and Cumulative Voting.
Under the statutory voting system, directors are elected one at a time. Each director is voted on one at a time. Therefore, a shareholder may give any one candidate, as a maximum, only a number of votes equal to the number of shares owned. Statutory voting favors majority shareholders.
Under cumulative voting system, total number of votes each shareholder may cast = (# of shares owned) x (# of directors to be elected). With cumulative voting, a shareholder may give all the votes he/she holds to a single candidate. Cumulative voting favors minority shareholders.

Example
“A” has 50 x 5 = 250 votes (all for Z)
“B” has 249 x 5 = 1,245 votes (÷ 5 = 249 for T, U, V, W, and Y)
