Description

A comprehensive guide to understanding the implications and applications of valuing employee stock options in light of the new FAS 123 requirements Due to the new requirements of the Proposed Statement of Financial Accounting Standards (FAS 123) released by the Financial Accounting Standards Board (FASB)-namely the fact that employee services received in exchange for equity instruments be recognized in financial statements-companies are now scrambling to learn how to value and expense employee stock options (ESOs). Based on author Dr. Johnathan Mun's consulting and advisory work with the FASB consulting projects with several Fortune 500 firms, Valuing Employee Stock Options provides readers with a comprehensive look at this complex issue. Filled with valuable information on binomial lattice and closed-form modeling techniques, Valuing Employee Stock Options can help financial professionals make informed decisions when attempting to ascertain the fair-market value of ESOs under the new requirements. Johnathan Mun, PhD, MBA, MS, CFC, FRM (San Francisco, CA), is Vice President of Analytical Services at Decisioneering, Inc., the makers of Crystal Ball analytical software. He is also the author of Applied Risk Analysis (0-471-47885-7), Real Options Analysis (0-471-25696-X), and Real Options Analysis Course (0-471-43001-3), all of which are published by Wiley.
