* Sees $20 mln-$30 mln losses from windstorm Xynthia
* Says actual losses may vary from estimates
March 12 (Reuters) - Bermuda reinsurer Validus Holdings Ltd (VR.N) said it expects losses of $170 million to $270 million related to the recent earthquake in Chile.
Validus also said it expects losses for expected claims from the European windstorm, Xynthia, to be between $20 million and $30 million.
Reinsurers essentially provide insurance to other insurers, allowing the risk of loss to be spread among several carriers.
