Options come with the obligation to pay for the underlying asset, so unless they are valued above the strike price, they are effectively worse than worthless.
Face value is unlikely to be the amount reported - I doubt the options are granted below the last reported market rate. Hence it's probably relative to the amount of underlying stock the options represent.
You'd have to check the SEC-filings for more accuracy than that.
Less than worthless would be when exercised, not exercising would be worth 0 - unless you paid for the option contract, in which case not exercising would represent a loss.
