(c) Making sufficient test checks to establish the audit's accuracy and compliance with Basic Manual rules when using summary type records as the payroll source;

(e) Providing guidance on recordkeeping practices to aid in future audits, including, but not limited to, maintenance of verifiable payroll records.

(a) Type of entity. With respect to the type of entity being insured, the insurer shall include factors and circumstances as follows:

(b) Sources and reconciliation. The insurer shall indicate the source record used to conduct the audit and the record used for reconciliation purposes. The most commonly used records include, but are not limited to, time records, payroll journal, individual earnings records, prepared summary, check book, cash book, petty cash book, general ledger, confidential ledger, bank statements, job cost records and tax returns (Federal, Social Security/State Unemployment). The auditor must be able to reconcile the audit product with the source record and be certain that appropriate records have been examined to verify the inclusion of all payroll. When summary type records are used as the audit source, sufficient sampling of the original payroll records must be made to ensure the inclusion of all payroll. The insurer must be sure that the auditor is able to check and list the dates (and amounts if readily available) of the opening and closing payroll period or periods (e.g., weekly and semi-monthly) in order to establish proper continuity from prior audits and for subsequent audits. This is also necessary for the purpose of proper audit review.

(c) Remuneration. The insurer shall investigate all possible sources of earnings, including those for uninsured contract employment.

(d) Overtime. The insurer shall indicate whether overtime was paid and, if so, whether the records are maintained in such manner as to permit the exclusion of overtime remuneration from total payroll, as allowed by Basic Manual rules. If overtime was paid but not properly recorded in the insured's records, the auditor shall provide the insured with guidance for maintaining overtime remuneration records to allow for credit on subsequent audits. This action shall be documented on the auditor's worksheet.

(e) Out of state operation. The insurer shall determine if the insured uses Oregon subject workers to perform work outside Oregon. Payroll for Oregon subject workers performing work outside Oregon must be included in the premium, based on protection provided through the extra-territorial provisions of Oregon law.

(f) Clerical employees, salesmen and drivers. The insurer shall:

(g) Classifications. The insurer shall determine the proper classifications. The insurer shall explain if the classifications assigned to the insured at audit differ from those shown on the insured's policy information page or bureau Inspection Report. Final premium charges are subject to ORS 737.310. The insurer shall obtain a detailed description of the insured's operations from the person or persons in the insured's organization best able to answer inquiries regarding the following:

(h) Additional classification information. The insurer shall examine the insured's first reports of occupational injury or illness as an additional source of classification information when classification issues require additional inquiry. The insurer's review may include electronic or paper documentation.

(i) Location. The insurer shall document any changes in the insured's locations. The insurer shall review payroll to assure that all locations have been included in the audit.

(j) Rate splits. The insurer shall determine if rate changes or normal anniversary rating dates require payrolls to be split;

(k) New construction or alteration. The insurer shall determine if structural alterations or new construction work on the insured's premises has been conducted by employees of the insured during the audit period. Payroll for these activities must be separately rated.

(l) New operations. The insurer shall identify any new operations, acquisitions or changes in operations.

(m) Longshore and Harbor Workers' Compensation Act operations. The insurer shall determine if the insured is engaged in operations subject to the Longshore and Harbor Workers' Compensation Act and if such operations are covered under the policy as evidenced by endorsement.

(n) Division of payroll. The insurer shall determine if the insured's records support a division of payroll between different classifications due to an interchange of labor, as provided for by OAR 836-042-0050 to 836-042-0060.
