We continue to adhere to a common-sense view of risk - how much we can lose and the probability of losing it. While this perspective may seem over simplisticor even hopelessly outdated, we believe it provides a vital clarity about the true risks in investing.

Beware leverage in all its forms. Borrowers - individual, corporate, or government - should always match fund their liabilities against the duration of their assets. Borrowers must always remember that capital markets can be extremely fickle, and that it is never safe to assume a maturing loan can be rolled over. Even if you are unleveraged, the leverage employed by others can drive dramatic price and valuation swings; sudden unavailability of leverage in the economy may trigger an economic downturn.

Almost no one will accept responsibility for his or her role in precipitating a crisis: not leveraged speculators, not willfully blind leaders of financial institutions, and certainly not regulators, government officials, ratings agencies or politicians.

In contrast to the speculators preoccupation with rapid gain, value investors demonstrate their risk aversion by striving to avoid loss.

In a world in which most investors appear interested in figuring out how to make money every second and chase the idea du jour, there's also something validating about the message that it's okay to do nothing and wait for opportunities to present themselves or to pay off. That's lonely and contrary a lot of the time, but reminding yourself that that's what it takes is quite helpful.

Investing today may well be harder than it has been at any time in our three decades of existence.

If another person were to enter the building, it would once again be empty.
