stock options simplified method

We are a small public accounting firm, Accountants CPA Hartford Connecticut, never having simplified publicly traded clients. SFAS allowed our nonpublic companies to continue to use the intrinsic value method of APB Opinion No. Since minimum value could be computed using either a present stock computation or an option pricing model, our firm always opted for the former method, avoiding the more mathematically forbidding one. However, with the implementation of SFAS R, the calculated value method is now required for nonpublic companies without an internal market for its stocks or options or for those unable to identify similar public entities for which share or option price information is available. The implementation of the simplified value method requires the use of an option pricing model and a volatility measure of an appropriate industry sector index. Like biblical exegesis scholars, our professional staff studied SFAS R searching for a comprehensive simplified of the calculated value method, illustrating in minute detail each step in its calculations method the valuing of a typical stock option of a method company. Unable to find such, and after spending days attempting to figure out the precise calculations required by eclectically piecing together what we found in the options literature, we decided to publish the results of our efforts in the hope of helping others who might have experienced similar difficulty in implementing the simplified value method and who desired a more comprehensive example illustrating its implementation in its entirety than is found in the Statement. SFAS R simplified that stock lattice model and a closed-form model are valuation techniques meeting its criteria for estimating fair values of employees share options, specifically mentioning the binomial model and the Black-Scholes-Merton formula as examples of stock, respectively. Although simplified Statement does not specify a preference for a particular valuation technique, as our option pricing model, we chose the Black-Scholes-Merton model to illustrate the calculated value method because not only is it the most widely known option-pricing model, but companies have rarely used the binomial model to measure option values under SFAS No. The Black-Scholes-Merton formula is options given in SFAS R. Method formula that we are employing in this illustration is the following:. Here, the assumptions under the option-pricing model are the following:. Typically the first three stock are fairly obvious and not worth further discussion; however, the latter three require further elaboration. The expected dividends on the stock is expressed as a continuously compounded annual percentage of stock price. To arrive stock a continuously compounded rate, one must take the natural logarithm of 1 plus the rate, k: Similarly, the risk-free rate, r, also method to be expressed as a continuously compounded yield for stock Black-Scholes-Merton model. Treasury zero-coupon issues with a remaining term equal to the expected term…. Again, one must take the natural logarithm of 1 plus the rate, which is the U. Treasury zero-coupon yield, y: Perhaps the most difficult variable to derive for the calculated value method of the pricing-option model involves the expected volatility. Here, expected volatility is the annualized standard deviation of the differences in the natural logarithms of the comparable industry sector indices for a options of time equal in length to the expected term of the option prior to the grant date. The annualized standard deviation is simply the product of the standard deviation as computed above times the square root of the number of periodic observations method the index in method year. If daily observations are used in the derivation of the standard deviation, simply multiply it by the square root of Stock historical values of the Dow Jones industry sector indexes can be obtained from the website, options With method index data downloaded into an Excel spreadsheet, add an adjacent column options the closing value ratio for each closing method In the next adjacent column, insert the natural logarithms of the closing value ratios just computed: Further assume that method company does not have an active market for its shares, and that there are no sufficiently comparable stock from which it could derive the value of its options. Further assume that the company has offered the following dividends over the past ten years:. The average dividend percentage is 4. Looking in the Wall Street Journal on February 28, for the U. Treasury zero-coupon simplified for an instrument maturing on February 28,one would find a yield of 4. The risk-free rate, a continuously compounded rate, is computed as follows:. Downloading the table in Stock, adding columns for the ratios of closing values and for their natural logarithms, and computing the annualized standard deviation are illustrated below:. Now one is ready to simplified the values of the variables into the Black-Scholes-Merton formula. Using Excel, we solve for:. Excel greatly simplifies the above calculations by providing readily computed values of the standard deviation and the standard normal distributions, which otherwise would require innumerable entries into options statistical calculator and simplified use of standard normal tables. Saving the Excel representation of the Black-Scholes-Merton formula and inserting the six requisite assumptions under the option-pricing model i.
