A business isn’t just worth the price of its fixed assets. In the case of compensatory damages they are going to look at current lost revenue, expectations for future lost revenue, personal damages to the owners that may make it harder for them to open up new businesses or get jobs, yada yada. It’s complex.
For example, let’s say you work out a business plan for a new business. You invest $1 million in the business infrastructure, and you understand that business will ramp up slowly and you need to build a community presence, goodwill, and trust before the big bucks come in. So in the first year you barely break even, and in the aecond year you make $10,000. But business is growing, and you are on track to be earning maybe 10 times as much in five years, then your plan is to expand and grow.
Now someone comes across and defames you in your second year, and organizes a boycott based on lies, and does grave damage to your reputation and forces you to close. How much damage did you suffer? Just the $10,000? Or $10,000 plus the million is cost you to start the business? What if you had spent another million on advertising? What if you were on track to be making $500,000 per year in five years, and that’s no longer going to happen?
Or for a closer scenario, let’s say you had a family business that had been in the area for 80 years, and you had built up extensive goodwill and name recognition, and you could expect your business to keep running for another 80 years. Then someone irreparably damages you and forces you to close. Are uou only entitled to the fixed value of the business? Clearly not. Things like brand value and relationships with suppliers and customers also have value, as does expectation of future profit.
I don’t know what the correct number is in Gibson’s case, but it sure as hell is 't the value of their fixed assets or a year’s worth of income. It’s much more than that.
