Yeah you can do that, but often companies keep track of the purchase value minus depreciation. Which means that something like a building is on the balance sheet for 1m, but the actual value might be 10m. the equity is basically the assets minus the liabilities which should be the value. However, paying dividend to the shareholder will lower the equity, but it will earn the shareholders money. So I would see a lot of companies doing that to lower their equity to pay less taxes.
Evaluating intellectual property is also pretty hard to do. Generally it has an original value and you depreciate on it as well.
All of the above depends on the country, the size and type of company it is, but generally it is pretty similar. Across the western world.
Them being an absolute moron hasn't affected the product for me or my experience with the rest of the company.
If I would stop using any and old company that had some bullshit owner, some bullshit thing done in the past or done currently I would basically have nothing I can use. The moment the opionins of him will start to impact the product I am out, but considering there is a foundation above the company which means he has a limited amount of impact I will wait and see before I act.
