QBE shares have gone into a trading halt pending an announcement on its North American operations.

The trading halt will be in effect until Tuesday.

The insurer requested the share-trading halt on the Australian Securities Exchange “in order to allow QBE time to finalise its analysis of information and review by the board, predominantly in relation to its North American operations, and the impact on QBE’s forecast financial result for the year ending 31 December 2013”.

QBE expects to brief investors on Monday.
