Financial data reporting II

Creating data extracts for the various reporting systems at an insurance group. Gross premium written (GWP): "When a non-life insurance company closes a contract to provide insurance against loss, the revenues (premiums) expected to be received over the life of the contract are called gross premiums written. Insurance companies often purchase reinsurance to protect themselves against the risk of a loss above a certain threshold; the cost of reinsurance (reinsurance premiums) is deducted from gross premiums written to arrive at net premiums written."
