ItemThe demand determinants of non-audit services: an empirical analysis with implications for auditor independence( 2001)Auditor independence is being increasingly questioned in a public debate about the joint provision of audit and non-audit services (NAS) by auditors to their corporate clients. Regulators are concerned that auditor firms which provide material consultancy services to their audit clients are likely to have their independence impaired either through conflicts of interest or fee dependence or both. Public accounting firms (the auditors) deny these risks. Positive accounting theories, such as agency theory and costly contracting theory, have supported the regulators' concerns by arguing that economic bonding between auditor and client is likely to be increased by the provision of NAS by the incumbent auditor, and hence lead to an impairment (real or perceived) of auditor independence. However, academic research into the nature of the association between auditor independence and the provision of non-audit services has been inconclusive and has failed to provide a definitive resolution to the debate. A reliable, comprehensive NAS fee model is a necessary prequel to greater insights into this debate. Guided by Firth (1997) and Craswell, Guz and Francis (2000), this study hypothesises a model reflecting three demand determinants for NAS: (i) the company's ex ante need for NAS, (ii) the auditor's NAS industry expertise and (iii) the company's willingness to appoint the auditor (given a portfolio of endogenous corporate governance practices and given a set of exogenous agency cost and political cost circumstances). The data set of 432 companies is selected from the "Top 500" Australian companies listed on the ASX in 1997. OLS regression analysis strongly confirms the model's first two demand determinants. First, a company's complexity, the extent of its restructuring activities, its appointment of a new CEO and its poor performance are all shown to be significant dimensions of its "need for NAS". Secondly, the important role of a NAS industry expert is a significant new finding in the NAS fee literature. The third determinant, the "willingness to appoint" is not comprehensively tested. Nevertheless some auditor independence issues associated with the "willingness to appoint" are explored. Auditor independence appears to be of concern to companies exposed to high political costs while it does not seem to be of concern to companies facing high agency costs. However, this study argues that auditor independence needs to be considered as part of a portfolio of other corporate governance practices/positions, which taken together, influence a company's willingness to appoint an incumbent auditor to the NAS consultancy. The demand determinants for NAS are also found to be robust across various partitionings of the data and in a novel re-specification of the model focussing on periodic increases in the level of NAS fees. Some limitations are acknowledged but exciting prospects for further fruitful research are recommended.

ItemAccounting conservatism: evidence from the oil and gas industry( 2004)Prior evidence in the oil and gas industry suggests that investors, when assessing firm value, seem to distinguish between different degrees of accounting conservatism that result from the application of the successful efforts (SE) method versus the full cost (FC) method. However, research addressing the valuation implications of accounting choice in the oil and gas industry primarily investigated periods prior to the issuance of SFAS 121. The effect of SFAS 121 on accounting conservatism in the oil and gas industry and hence on the usefulness of the SE method, relative to the FC method, remains untested. This study extends the existing literature by re-examining the effect of accounting conservatism on the usefulness of accounting numbers produced by SE and FC methods during the period 1995-2001, a period in which both SFAS 121 and the ceiling test rules were applied. Empirical results show that in an environment of both SFAS 121 and the ceiling test, there is no difference between SE and FC firms with respect to conservatism associated with the application of accounting rules. Moreover, the results show that the usefulness of accounting numbers to investors does not differ across SE and FC methods. That is, investors attach no valuation premium of one method over the other in the oil and gas industry. This examination provides updated evidence that should be of interest to regulators and standards setters.
