Audit style implies that two companies audited by the same auditor, subject to the same audit style, are more likely to have comparable earnings than two firms audited by two different audit firms with different styles.

In the present study used correlation method and multiple regression and is performed regression analysis for hypothesis test. The findings show that the clients of audit firms in the same industry and year than to their non-clients have more similar in accruals and earnings structure. Also the auditor style has an effect on clientele accruals, and that a change to the same auditor leads to more similar accruals.
