GENEVA, May 22 (Reuters) - Richemont, the maker of Cartier watches, Piaget jewellery and Montblanc pens, said it is considering splitting itself into two units as it matched market forecasts with an 18 per cent rise in full-year net profit.

The Swiss luxury good company said it was mulling a proposal to become two entities -- a luxury business headquartered in Switzerland, and an investment vehicle which could be based in Luxembourg and structured as an investment fund.
