Nope, I did not. I clearly mentioned the account initial balance etc., and most importantly I did not want to set up a whole charter of accounts. You cannot simply say the sum of all accounts should be zero, depending on the convention used, the balance of account can all be positive. The only thing you can say for sure is that sum of all credit amounts minus all debit amounts should be zero.

I don't think those listed companies tend to undervalue their inventories as it will make their balance sheet ugly and potentially reducing their ability to raise more capital. But even if they did do so, those gaps should be shown in accounts like unrealized loss etc instead of just evaporate. Tesla has a professional accounting team, it's impossible they made such mistakes.
