11 November 2011 Last updated at 11:59 GMT

Land Securities chairman Alison Carnwath says you need to try to ensure your company is robust enough to cope if the unthinkable should happen, a lesson she learned during the collapse of property values during 2007/2008.

Alison appeared on The Bottom Line, which was broadcast on BBC Radio 4, the BBC World Service and the BBC News Channel. You can also download the podcast.
