OREANDA-NEWS. Fitch Ratings has published a periodic review and update of its methodology for rating insurance-linked securities (ILS). This report replaces the criteria of the same title published in August 2014.

Fitch added clarity surrounding ILS impairments, treatment of investment volatility within collateral accounts and interpretation of the calibration matrix. None of these updates had any effect or altered any current ILS credit ratings.

Fitch's 'Insurance-Linked Securities Methodology' is a sector-specific rating criteria, so it also draws on other criteria from Structured Finance and Insurance in developing the rating.

The full report 'Insurance-Linked Securities Methodology' is freely available on the Fitch website at 'www.fitchratings.com'.
