Fortune Magazine released its annual

of top-grossing companies in the U.S., and Wal-Mart reigns supreme after coming in second place last year.

But, there's one notable drop for one local company. General Motors drops from No. 6 to No. 15. As Fortune points out, it's the first time in the automaker's 101-year history it wasn't in the top 10.

Ford, however, is in the top 10, although it dropped one rung from No. 7 to No. 8 this year.

Other companies in the top 10, in descending order: Exxon Mobil, Chevron, General Electric, Bank of America, ConocoPhillips, AT&T, Ford, J.P. Morgan Chase and Hewlett-Packard.

Elsewhere in the top 100, Dow Chemical ranks at No. 46 (down from No. 38).
