Magister Scientiae - MSc / We investigate some simulation-based approaches for the valuing of the employee stock options. The mathematical models that deal with valuation of such options include the work of Jennergren and Naeslund [L.P Jennergren and B. Naeslund, A comment on valuation of executive stock options and the FASB proposal, Accounting Review 68 (1993) 179-183]. They used the Black and Scholes [F. Black and M. Scholes, The pricing of options and corporate liabilities, Journal of Political Economy 81(1973) 637-659] and extended partial differential equation for an option that includes the early exercise. Some other major relevant works to this mini thesis are Hemmer et al. [T Hemmer, S. Matsunaga and T Shevlin, The influence of risk diversification on the early exercise of employee stock options by executive officers, Journal of Accounting and Economics 21(1) (1996) 45-68] and Baril et al. [C. Baril, L. Betancourt, J. Briggs, Valuing employee stock options under SFAS 123 R using the Black-Scholes-Merton and lattice model approaches, Journal of Accounting Education 25 (1-2) (2007) 88-101]. The underlying assets are studied under the GARCH (generalized autoregressive conditional heteroskedasticity) effects. Particular emphasis is made on the American style employee stock options. / South Africa

The objective of my thesis is to outline the evolution of accounting regulation. The thesis describes development of accounting, first regulation forms, emergence of double entry and present globally accepted accounting standards. In my work I enlarge the development of two well known accounting standards GAAP and IAS and their regulation. The convergence project between standard setters' bodies is elaborated as part of present development of accounting regulation. One of next titles in my thesis is the accounting harmonization process in EU as part of accounting regulation and the adoption of IAS standards by EU Commission

The work aims to analyze the new leasing standard which is supposed to be adopted by IFRS as well as US GAAP. The new standard represents one of the steps in the process of harmonization and convergence between two predominant world accounting standards, which has been in progress since the year 2002. The work provides readers with the comparison of these two leasing standards, resulted from which the need of common lease standard arose. This led to the first exposure draft of convergence standard issue, and finally the re-exposure draft issue. Because the new accounting standard is still in progress, I provide the analysis of the process as at the end of August.

As a response to the financial crisis of 2008 the IASB and the FASB developed IFRS 9 and ASC 326, respectively. These accounting regulations are supposed to increase reporting transparency and promote financial stability by determining the calculation and recognition of loan loss provisions. However, previous literature has brought up concerns that loan loss provisions can negatively impact the lending activity in banks. If that was the case, they would negatively affect the amount of capital available in an economy and thereby threaten financial stability and economic growth especially during times of economic downturns. To shed light on this topic, this thesis investigates the relationship between loan loss provisions and lending activity in banks applying IFRS and US GAAP. The thesis provides practical as well as theoretical implications as it discusses the findings in a practical context and relates it to relevant theories.  The dataset utilized includes empirical data from Q1 2020 until Q4 2022 and covers 330 banks from 38 countries. The data was gathered from Refinitiv´s Eikon database as well as from the International Monetary Fund. It was then statistically analyzed by conducting different kinds of statistical inference. All methods applied are of a quantitative nature and the underlying methodology is positivist. The results of this thesis suggest that loan loss provisions under IFRS 9 are on average higher than under ASC 326. Further, it was found that loan loss provisions under IFRS 9 exhibit a statistically significant negative relationship with lending activity. In contrast, this relationship was found to be insignificant under ASC 326. Together, these findings suggest that higher loan loss provisions have a negative effect on lending activity. It is concluded that the impairment model of IFRS 9 might compromise financial stability by limiting lending activities during times of economic turmoil.  Additionally, due to the increased room for managerial judgment under IFRS 9 it is theorized that the higher loan loss provisions can be the result of earnings management. Loan loss provisions under IFRS 9 could thus be more supported by Agency theory. On the other hand, ASC 326 offers less room for managerial discretion and could be more supported by Stewardship theory. This thesis also suggests topics for potential future research. The knowledge about loan loss provisions and their effects on lending activity could be extended by using different variables in the regression model. Additionally, a longer timeframe as well as other accounting standards could be investigated. Furthermore, the effects of loan loss provisions on loan quality and risk management in banks are in need of further examination. Lastly, the capital requirements of Basel III and their impact on procyclicality should be researched.

The aim of this thesis is to create a comprehensive view of financial reporting of lease contracts from lessee's and lessor's point of view in accordance with International Financial Reporting Standards (IFRS) and US Generally Accepted Accounting Principles (US GAAP). The thesis is divided into four parts. The first part is devoted to basic characteristics of the lease and its reporting according to the currently applicable standards - IAS 17 and ASC 840. Content of the next part is Convergence of Accounting Standards. Second half of the thesis focuses on the Exposure Draft and Comment Letters.
