Warren Buffett's Berkshire Hathaway made public the state of its portfolio of investments and disclosed a stake in insurer Chubb.

Shares of Chubb rose 5.9% to $268 in after-hours trading, with the stock up 27% over the past 12 months.

Berkshire owned 25.9 million shares in Chubb at the end of March, according to a Securities and Exchange Commission filing published after the close on Wednesday. The investment was worth $6.72 billion.

In its latest results, Chubb said first-quarter total company net premiums written climbed more than 14% to $12.22 billion amid a 26% increase in life insurance net premiums written.

"Looking forward, we are confident in our ability to continue growing operating earnings at a rapid pace through P&C revenue growth and underwriting margins, investment income, and life income," Chief Executive Evan Greenberg said.
