This thesis examines the extent to which benchmark beating by Australian firms around the earnings level and earnings changes thresholds can be reliably interpreted as evidence of earnings management. A number of recent academic papers challenge the earnings management explanation for the observed kinks in the distribution of net Income. In response to this criticisms, this thesis is motivated to conduct tests of earnings management with a refined methodology of selecting a subset of firms immediately above the threshold that have a priori incentives to achieve the benchmark. This approach allows for investigations to focus on benchmark beating observations where earnings manipulations would be more prevalent and thereby provide a powerful test for the existence of opportunistic reporting. The paper uses a number of unexpected accruals measures including the Kothari et al. (2005) performance matched models. In testing the hypotheses, this thesis utilises two approaches which were; the regression approach and the test of difference of means approach. Based on a broad sample drawn from all listed Australian firms for the years 1995-2007, small profit firms and small increase firms with high price-to-sales ratio were found to have evidence consistent with opportunistic benchmark beating behaviour. Similar results are also documented for benchmark beating firms with low book-to-market (high market-to-book) ratio. This thesis also finds that firms with equity offering incentives who reported improvement in earnings display unexpected accruals consistent with earnings management. In addition, the accounting behaviour of firms which previously incurred a loss is consistent with earnings management explanation. Firms with long strings of earnings increases also appear to use accounting discretion in order to avoid earnings deterioration. Similarly, evidence of earnings management are also displayed by small profit firms which have consistently reported negative earnings. Finally, this thesis provides evidence that resolves the apparent paradox that benchmark beating is evidence of earnings management which is devoid of the statistical artefact argument posited by Durtschi and Easton (2005) and Durtschi and Easton (2008).

Redovisningskvalitet på små aktiebolag har påvisats minska sedan revisionskravet slopades. Det förekommer en diskussion om huruvida revisionskravet behöver återinföras eller om gränsvärdena för revisionsplikten ska utökas. Debatten är för tillfället delad, en part menar att gränsvärdena för när aktiebolag ska ha revisor ska höjas. Den andra menar att fördelen med att även små aktiebolag har revisor är att det säkerställer kvaliteten på redovisningen. Att redovisningskvaliteten säkerställs är av intresse för intressenter till små aktiebolag på grund av informationsasymmetrin som råder. Det finns fördelar för bolagen med att inte omfattas av revisionsplikt, den främsta fördelen är ekonomiska lättnader för bolagen. Studien exemplifierar konsekvenser som kan drabba fler än de intressenter som är närmast anknyta till bolaget. Samhället kan drabbas negativt om bolagen inte sköter sin redovisning alternativt begår ekonomisk brottslighet som en konsekvens av att extern granskning av räkenskaperna saknas. Tidigare forskning visar att det föreligger ett samband mellan oväntade periodiseringar och redovisningskvalitet. Studien som genomförts påvisar att det föreligger ett samband mellan att redovisningskvaliteten har minskat och slopandet av revisionsplikten. Av resultatet framgår att kvaliteten på redovisningen, som undersökts genom oväntade periodiseringar, har minskat för små aktiebolag inom byggbranschen, sedan revisionskravet har slopats. Konsekvenser av att revisionsplikten slopats kan leda till att intressenter inte förlitar sig på bolaget. Det kan skada både bolag och intressenter att förtroendet för små aktiebolag minskar som en följd av att det inte längre finns ett krav på revisor. Undersökningen som gjorts påvisar att redovisningskvaliteten har minskat över tid och som följd har belastningen på myndigheter ökat, sedan revisionsplikten slopades. / The quality of the accounting in small companies has proven to decline since the audit requirement was abolished. An ongoing discussion exists concerning whether the audit requirement should be implemented once again or if the limit values should be expanded. The parties in the discussion currently have different opinions where one party argues that the limit value concerning the audit requirement should increase. The other party claims that the pro of small companies using an auditor is that the auditor ensures the quality in the financial reports. High quality in the accounting is of interest for the stakeholders of small companies since information asymmetry is present. There are pros for companies that are not obligated to use an auditor, where the major pro is economic relief for the companies. However, except for the stakeholders with the closest connection to the company, consequences can also affect other parties. Society could be negatively affected if companies produce inadequate information in the financial reports or if the companies commit economic crime which are both consequences of the lack of external auditing of the financial information. Previously research indicate a relationship between unexpected accruals and accounting quality. The results indicate that the quality of the accounting, measured through unexpected accruals, has declined for small companies within the building sector, since the audit requirement was abolished. Consequences of the abolishment of the audit requirement could be that the stakeholders don't trust the company. Lost trust in small companies as a consequence of the abolishment of the audit requirement could hurt both the small companies and the stakeholders. The study proves that the quality of the accounting has decreased and the load on the authorities has increased over time, after the audit requirement was abolished.
