Jamie Dimon (JP Morgan Chase), Warren Buffet (Berkshire Hathaway), Mary Barra (General Motors), Jeff Immet (GE), Larry Fink (Blackrock) and other executives think so and have published a set of "Commonsense Principles of Corporate Governance" for public companies. There are more specifics in the Principles, but the key points cribbed from the front page of the new website are as follows:

Truly independent corporate boards are vital to effective governance, so no board should be beholden to the CEO or management. Every board should meet regularly without the CEO present, and every board should have active and direct engagement with executives below the CEO level;

■ Diverse boards make better decisions, so every board should have members with complementary and diverse skills, backgrounds and experiences. It’s also important to balance wisdom and judgment that accompany experience and tenure with the need for fresh thinking and perspectives of new board members;

■ Every board needs a strong leader who is independent of management. The board’s independent directors usually are in the best position to evaluate whether the roles of chairman and CEO should be separate or combined; and if the board decides on a combined role, it is essential that the board have a strong lead independent director with clearly defined authorities and responsibilities;

■ Our financial markets have become too obsessed with quarterly earnings forecasts. Companies should not feel obligated to provide earnings guidance — and should do so only if they believe that providing such guidance is beneficial to shareholders;

■ A common accounting standard is critical for corporate transparency, so while companies may use non-Generally Accepted Accounting Principles (“GAAP”) to explain and clarify their results, they never should do so in such a way as to obscure GAAP-reported results; and in particular, since stock- or options-based compensation is plainly a cost of doing business, it always should be reflected in non-GAAP measurements of earnings; and

■ Effective governance requires constructive engagement between a company and its shareholders. So the company’s institutional investors making decisions on proxy issues important to long-term value creation should have access to the company, its management and, in some circumstances, the board; similarly, a company, its management and board should have access to institutional investors’ ultimate decision makers on those issues.

I expect that shareholder activists, proxy advisory firms, and corporate governance nerds like myself will scrutinize the specifics against what the signatories’ companies are actually doing. Nonetheless, I commend these business leaders for at least starting a dialogue (even if a lot of the recommendations are basic common sense) and will be following this closely.
