Oct. 4 (Bloomberg) -- Liberty Mutual Holding Co. insurance units may be upgraded by Standard & Poor’s for doing a better job than the industry of limiting costs from natural disasters.

The outlook was raised to “positive” from “stable” as “performance compares favorably to that of peers,” the ratings firm said today in a statement on the Boston-based insurer. “Liberty has strong catastrophe risk controls and we don’t expect the company to be a negative outlier in terms of natural catastrophe losses.”
