Tricky times for Foxconn

30 October 2012 Last updated at 14:00 GMT

Taiwan's Hon Hai, which trades under the name Foxconn, is set to report its third quarter earnings, amid unrest amongst its workers and rising production costs.

Issues relating to Apple's iPhone 5 led some staff to take strike action and production at a north China plant was halted in September following a riot.

The company, which makes smartphones, tablet computers and other gadgets for some of the biggest technology companies, is also facing rising costs, which could see it lose its competitive edge.
