how they might be augmented by incoming directors. We believe that directors are in the best position to assess the optimal size for the board, but we would be concerned if a board seemed too small to have an appropriate balance of directors or too large to be effective.
There are matters for which the board has responsibility that may involve a conflict of interest for executives or for affiliated directors. BlackRock believes that shareholders’ interests are best served when the board forms committees of fully independent directors to deal with such matters. In many markets, these committees of the board specialize in audit, director nominations and compensation matters. An ad hoc committee might also be formed to decide on a special transaction, particularly one with a related party or to investigate a significant adverse event.
Auditors and audit-related issues
Comprehensive disclosure provides investors with a sense of the company’s long-term operational risk management practices and, more broadly, the quality of the board’s oversight. In the absence of robust disclosures, we may reasonably conclude that companies are not adequately managing risk.
BlackRock recognizes the critical importance of financial statements, which should provide a true and fair picture of a company’s financial condition. We will hold the members of the audit committee or equivalent responsible for overseeing the management of the audit function. We take particular note of cases involving significant financial restatements or ad hoc notifications of material financial weakness.
The integrity of financial statements depends on the auditor being free of any impediments to being an effective check on management. To that end, we believe it is important that auditors are, and are seen to be, independent. Where the audit firm provides services to the company in addition to the audit, the fees earned should be disclosed and explained. Audit committees should have in place a procedure for assessing annually the independence of the auditor.
Capital structure, mergers, asset sales and other special transactions
The capital structure of a company is critical to its owners, the shareholders, as it impacts the value of their investment and the priority of their interest in the company relative to that of other equity or debt investors. Pre-emptive rights are a key protection for shareholders against the dilution of their interests.
Effective voting rights are central to the rights of ownership and we believe strongly in one vote for one share as a guiding principle that supports good corporate governance. Shareholders, as the residual claimants, have the strongest interest in protecting company value, and voting power should match economic exposure.
We are concerned that the creation of a dual share class may result in an over-concentration of power in the hands of a few shareholders, thus disenfranchising other shareholders and amplifying the potential conflict of interest, which the one share, one vote principle is designed to mitigate. However, we recognize that in certain circumstances, companies may have a valid argument for dual-class listings, at least for a limited period of time. We believe that such companies should review these dual-class structures on a regular basis or as company circumstances change. Additionally, they should receive shareholder approval of their capital structure on a periodic basis via a management proposal in the company’s proxy. The proposal should give unaffiliated shareholders the opportunity to affirm the current structure or establish mechanisms to end or phase out controlling structures at the appropriate time, while minimizing costs to shareholders.
In assessing mergers, asset sales or other special transactions, BlackRock’s primary consideration is the long-term economic interests of shareholders. Boards proposing a transaction need to clearly explain the economic and strategic rationale behind it. We will review a proposed transaction to determine the degree to which it enhances long-term shareholder value. We would prefer that proposed transactions have the unanimous support of the board and have been negotiated at arm’s length. We may seek reassurance from the board that executives’ and/or board members’ financial interests in a given transaction have not adversely affected their ability to place shareholders’ interests before their own. Where the transaction involves related parties, we would expect the recommendation to support it to come from the independent directors and it is good practice to be approved by a separate vote of the non-conflicted shareholders.
BlackRock believes that shareholders have a right to dispose of company shares in the open market without unnecessary restriction. In our view, corporate mechanisms designed to limit shareholders’ ability to sell their shares are contrary to
