Workers’ Compensation Insurance: WCI is based upon several factors, and is primarily composed of the Trade Rate, based on the type of work the Contractor performs, and the firm's Experience Modification Rating (EMR), which is based on the Contractor's specific claim history. The Trade Rate is statutorily mandated and can be derived directly from the WCI policy premium calculation provided by the insurance company. To reward Contractors with a low EMR or that have earned other discounts on their WCI policy, the Trade Rate used on the HLRW will not be adjusted lower than the rate incurred by the Contractor, which would effectively reduce the labor rate for these earned discounts. However, to properly compensate Contractors that incur additional WCI premiums for higher EMR's, or pay other adjustments to their premiums, an adjustment field has been provided to capture these increases in WCI cost. This adjustment field should only be used if the net of all adjustments to the policy premium results in higher premium charges. Once the combined WCI rate has been determined, populate the appropriate cell in the HLRW - the HLRW will not automatically update based on the calculations below.
