Numerous value relevance investigations use the Ohlson (1995) model to empirically explore the value relevance of accounting variables such as earnings and goodwill amortisation by employing equity price as the dependent variable, but do not incorporate the most recent prior period’s equity price as an additional explanatory variable. The Ohlson (1995) model and the efficient market literature indicate that, since share prices represent the present value of future permanent earnings in an efficient market, the most recent prior period’s equity price should be a crucial variable for explaining the current price in value relevance models. This thesis therefore outlines how the Ohlson (1995) model incorporates the most recent prior period’s price as a potentially important value relevant explanatory variable, and reformulates the Ohlson (1995) model to demonstrate how the empirical specification of value relevance regression models can be greatly improved by including the most recent prior period’s price as an additional explanatory variable. We revisit the Jennings, LeClere, and Thompson (2001) empirical specification used to study whether goodwill amortisation is value relevant and potentially informative with respect to future earnings to illustrate the improvement to the Ohlson (1995) value relevance model empirical specification. When the model specification is improved by including the most recent prior period’s price as an additional explanatory variable, trailing earnings are shown, using time series, cross-sectional, and returns-based analysis, to be at best marginally value relevant when empirically explaining share prices in value relevance regression models. The thesis also indicates that goodwill amortisation should not be deducted from earnings in accounting statements because the presence of goodwill amortisation is significantly positively (not negatively) related to equity prices. This effect is eliminated when the most recent prior period’s price is included as an additional explanatory variable in the regression analysis, thus indicating that goodwill amortisation information as well as trailing earnings information have already been incorporated into the most recent prior period’s price. The thesis further indicates that value relevance studies that use the Ohlson (1995) model should use, for econometric reasons, change in price or else returns, not the price level, as the dependent variable. When returns are used to test the value relevance of goodwill amortisation, firms that report positive goodwill amortization actually have higher subsequent returns, a result that could possibly be due to the fact that growing firms tend to possess goodwill when they use acquisitions to expand. Results obtained when using returns to test whether goodwill amortisation is value relevant therefore extend the existing literature, since the prevailing expectation in the accounting literature is that goodwill amortization either represents a reduction in the value of goodwill over time or is not value relevant.

The perennial controversy in business combinations accounting and its dialectic with stakeholders’ interests under the complexity of the Mergers and Acquisitions (M&A) activity is the centrepiece of analysis in this thesis. It is argued here that the accounting regulation should be as neutral as possible for the economic activity, although it is recognised that accounting changes may result in economic effects. In the case of the changes for business combinations accounting in the USA, lobbying was so fierce that in order to achieve the abolition of accounting choice in M&A accounting, it forced the standard-setter to compromise and to change substantially some of its earlier proposals. Such fierce lobbying cast doubts about whether it was effectively possible to mitigate such economic effects, resulting in a possible impact of the accounting changes on the M&A activity. The occurrence of M&A in waves is yet to be fully theorised. Nevertheless, existing literature established relationships between M&A activity and some key economic and financial factors, and has provided several interesting theories and other meaningful contributions for this thesis. It was therefore possible to examine whether the changes in the accounting rules produced any significant impact on the M&A activity. The findings obtained from the testing of the research hypotheses suggest that the new M&A accounting rules did not result in significant impacts on overall M&A activity. Nevertheless, from the study of managers’ perceptions, and from the examination of annual reports of S&P 500 companies, a considerable impact on the financial reporting was found.

The principal goal of this research study was to critically evaluate the current accounting treatment of purchased goodwill in terms of a theoretical framework established, including an evaluation of the true nature of goodwill. The main conclusion of this study is that goodwill is an intangible asset representing various intangible factors contributing to the enterprise's earning capacity and providing returns in excess of a normal return on assets employed for which an acquiring enterprise is willing to pay an amount in excess of the fair value of the identifiable net assets acquired. The cost of purchased goodwill is measured as the difference between the total purchase price and the fair value of the net assets acquired after ensuring that all assets, tangible and intangible, had been properly identified. Purchased goodwill should be amortised over the estimated period that the enterprise is expected to benefit from the acquisition of the goodwill. / Financial Accounting / M. Com.
