The Corporation must, in a manner and form determined by the Corporation, maintain a separate account for each employer in which the Corporation records—
(a) the premiums, fees and supplementary payments charged to the employer; and
(b) the amounts paid by an employer; and
(c) the costs related to claims (whether under this Act or at common law) arising from employment by the employer, distinguishing the costs related to claims for unrepresentative injuries from the other claims; and
(d) all other costs attributable to the employer; and
(e) any other matter that the Corporation thinks fit.
