Options on 100 Million shares at $10 are worth about $0.00 if the price of the stock is $2.If the price of the stock rises to $12, then those options are worth at least $200 Million.
If the price of the stock rises to $14, then those options are worth at least $400 Million.
Stock prices rise and fall every day. Some people will exercise their options at the right time. Other people will wait and the stock will drop down below $10 making their options worthless again (generally). Timing is everything. You won't know what those options cost the company until they are all exercised or expired.
In the history of investing, some 80% of all options expire worthlessly.
If you force a company to guess at what the options will be worth when they are exercised, then you will be forcing companies to engage in pretend accounting. That company's books will no longer reflect the actual cash on hand, but will reflect a guess of what its cash should be if option-holders behave a certain way and the stock price moves a certain way.
That's not accounting. That's fantasy-land. Alice is through the looking glass once corporations start making guesses as to how much cash they "should" have on hand under certain market conditions.
No, the better solution is to do what we are doing today: counting the actual revenue and the actual expenses paid, when those expenses are finally paid. At least this method tells us accurately where we are financially today.
Changing over to this new "expensing options" craze will destroy even that last tidbit of worthy justification for accounting. Might as well save your money by not doing any accounting as to force companies to write such guesses on future option-values into the books.
