OMAHA, Neb. (AP) — Warren Buffett’s company will release its second-quarter earnings report on Friday afternoon.

Investors will also be looking for clues about what Buffett might invest in next and whether the economy will improve because Berkshire Hathaway’s results offer a glimpse into an assortment of industries.

The bottom line profit Berkshire reports on Friday is likely to be hurt by the paper value of its derivatives that are tied to several stock-market indexes.

The true value of the derivatives won’t be clear for at least several years, because they don’t mature until nearly a decade from now. But Berkshire is required to estimate their value every time the company reports earnings.
