Washington Revised Code Title 48. Insurance § 48.35.020. Deposit required--Amount

(1) An alien insurer may use this state as a state of entry to transact insurance in the United States by maintaining in this state a deposit of assets in a solvent trust company or other solvent financial institution having trust powers domiciled in this state and so designated by the commissioner.
