An insurer's premiums recorded as written in a specific period, net of premiums assumed and ceded. The difference between written premiums and earned premiums is amortization. For example, a one-year policy written in November has its premium recorded as written entirely in that year, while 1/12 of the premium is earned each month over the period insured.

The total sum of all types of premiums written by an insurer, minus any premiums ceded to reinsurers.

This item represents gross premium written, direct and reinsurance assumed, less reinsurance ceded.
