(d) For purposes of this section, an assessment is authorized at the time a resolution by the board is passed under which an assessment will be called immediately or in the future from member insurers for a specified amount and an assessment is called at the time a notice has been issued by the association to member insurers requiring that an authorized assessment be paid within a period stated in the notice. An authorized assessment becomes a called assessment at the time notice is mailed by the association to member insurers.
