Final answer:
Without specific information on the FWCJUA Tier 2 coverage, we cannot determine the correct annual fee percentage. Additional details on the FWCJUA coverage tiers are needed to provide an accurate answer.
Step-by-step explanation:
The question pertains to the Florida Workers Compensation Joint Underwriting Association (FWCJUA), more specifically, the required payment for a company that is assigned to Tier 2 for coverage. Unfortunately, without specific information related to the Tier structures and the corresponding percentages from the FWCJUA, the exact answer to the question of whether a company in Tier 2 must pay 5%, 10%, 15%, or 20% of the annual fee cannot be provided. The financial breakdown provided from the 2005-2008 seasons, including costs related to nest protection and subsequent percentage calculations, is not sufficiently related to the FWCJUA coverage tiers to deduce the correct percentage for a Tier 2 assignment payment. Therefore, the correct answer to this question would require additional information specific to the FWCJUA tiered coverage plan.
