A classified board of directors, also known as a staggered board, is a corporate governance structure that dictates the election cycle of board members. This arrangement divides the board into separate classes with overlapping terms. The structure controls the speed at which shareholders can replace the entire board. This mechanism influences the balance of power between management and shareholders, making it a significant factor in evaluating a firm’s governance profile.
Understanding the Structure of a Classified Board
A classified board operates by dividing its total number of directors into classes, most commonly three. These classes are typically of equal size, and the structure is established within the company’s corporate charter or bylaws. The defining feature is that the terms of the directors in these classes do not expire at the same time.
Directors are generally elected for three-year terms, with one class up for re-election at each annual shareholder meeting. This staggering mechanism ensures that only a fraction of the board, usually one-third, stands for a new term in any given year. A majority of the board members remain in place after the annual meeting, providing continuity. A shareholder seeking to replace a majority of the board must succeed in two consecutive annual elections.
The Difference Between Classified and Declassified Boards
The classified board structure contrasts sharply with a declassified, or unitary, board, where all directors are elected annually. In a declassified system, every director serves a one-year term and must stand for re-election at the subsequent annual meeting. This provides shareholders the opportunity to vote on the entire composition of the board every year.
The core distinction lies in the frequency and volume of directors subject to shareholder approval. The declassified structure provides shareholders with a direct mechanism to alter the board’s direction. Conversely, the classified structure limits shareholders to voting only on the directors in a single class each year, insulating the board from rapid change.
Strategic Advantages for Companies
Companies often favor a classified structure for the stability it provides to corporate operations. By ensuring directors serve multiple-year terms, the board retains experienced members through volatile market conditions or executive transitions. This continuity allows the board to focus on long-term strategic planning without the pressure of re-election.
The primary strategic advantage of a classified board is its function as a defense against a hostile takeover attempt. This mechanism makes it impossible for an activist investor to gain immediate control of the board. A bidder must wait for two separate annual meetings to elect a majority of directors, a delay that provides the current board time to negotiate or explore alternatives. The necessity of a multi-year effort often deters potential hostile bidders.
Impact on Shareholder Rights and Accountability
While classified boards offer stability, investors criticize them for reducing director accountability. Since directors are not subject to a full shareholder vote every year, they may become less responsive to investor concerns or underperforming company results. This insulation can lead to the entrenchment of existing management, making it difficult for shareholders to effect change.
The structure limits the effectiveness of proxy access, which is the right of shareholders to nominate their own candidates. Even if shareholders win a proxy contest, they can only replace one-third of the board in that election cycle, preventing a swift overhaul. Studies indicate that classified boards can be associated with reductions in company valuation due to poor governance metrics. This suggests the market perceives lower accountability as a detractor from shareholder wealth.
The Shift Away from Classified Boards
The historical popularity of classified boards has steadily declined due to increasing pressure from the investment community. Institutional investors, such as large pension funds and mutual funds, oppose these structures, viewing them as obstacles to good governance. Proxy advisory firms, including Institutional Shareholder Services (ISS) and Glass Lewis, also recommend that shareholders vote in favor of declassification proposals.
This collective pressure has driven a widespread trend toward declassification, particularly among the largest public companies. For instance, the percentage of S&P 500 companies with classified boards has dropped to approximately 10-12%. Removing this structure requires a shareholder vote to amend the corporate charter or bylaws, and declassification proposals routinely receive overwhelming support. This shift reflects a broader demand for greater board transparency and direct shareholder oversight.
