General Electric has completed its split of the one-time conglomerate into three separate companies, as its aerospace and energy businesses started trading on the New York Stock Exchange as separate entities on Tuesday.

General Electric is revealing the names of the three companies that will operate on their own after the historic split of the one-time conglomerate.

Paycom Software’s Chad Richison and Advanced Micro Devices’ Lisa Su are among the top paid CEOs in the S&P 500 index.

General Electric narrowed its losses in its third quarter as it trimmed expenses and managed to post an adjusted profit that surprised Wall Street. GE lost $1.19 billion, or 13 cents per share, for the three months ended Sept.30. A year earlier the Boston-based company lost $9.47 billion, or 15 cents per share. Earnings, adjusted for one-time costs and asset impairment costs, were 6 cents per share. For the year to date, it has reduced debt by $11.7 billion, including $8.1 billion in GE Industrial debt and $3.6 billion in GE Capital debt.
