Expressed as low frequency (meaning the loss event is possible but has rarely happened in the past and is not likely to occur in the future), moderate frequency (meaning the loss event has happened once in a while and can be expected to occur sometime in the future), or high frequency (meaning the loss event happens regularly and can be expected to occur regularly in the future). Workers compensation losses normally have a high frequency as do automobile collision losses. General liability losses are usually of a moderate frequency, and property losses often have a low frequency.
