Redovisning av personaloptioner enligt IFRS 2 : En studie i värderingsmodellerna och dess indata
Abstract (Summary)19th February 2004 the IASB introduced the IFRS 2. IFRS 2 means that the corporations must handle employee stock options as a cost in the income statement. It is not regulated in the constitution which model that should be used to value the options. Because of this the income statement can be affected by which model that is used by the corporation. The purpose of this paper is to confirm which affects different valuing models has to the value of the corporations employee options and even describe which assumptions of the in data that are used by the corporations and examine if this assumptions are theoretical correct. The paper is based on a case study of ten corporations who has employee stock option programs which are accounted according to the IFRS 2. At the comparing of the option valuing models the corporations in data is placed into the two models and calculations are made to see if the values vary between the models. Because that volatility is a very important factor in the option valuing models and affects the theoretical value at a significant extent an examination which is mean to give a picture of how the corporations has create the volatility assumption and that even will study if this value is correct theoretical value. Only 35 of the original 102 (34 %) corporations had employee stock options which are accounted according to the IFRS 2. Only 10 of these 35 (28,57 %) had a complete information about the in data. After my estimation of the historical volatility, five years back in time, my estimated volatility was in average 216,43 % higher than what the corporations had estimated and the average value of the options was 179,53 % higher. An estimation of the historical volatility one year back in time I get a lower value of the volatility that is in average 41,39 % higher than the corporations estimation and a option price that is 39,13 % higher. The differences of the risk free interest rate are huge, from 2,00 % to 4,30 %, a difference at 215 %. The calculated variation between the Black & Scholes model and the binomial method is tiny. The average difference between the ten examined corporation are only 0,0059 %, i.e. a hardly noticeable difference.
