They are the ones that have been spent on the business or those that have been used to keep the business alive. The owner's equity is the capital that is used to start the business. This is need to be know in order to really see if the capital has been earned back, has the possibility of being earned back or impossible to earn back at all. Financial statements contain the data needed to be compared in order for the owner to know if his company or business is actually earning something or not.
Although it may be tough to keep or make a financial statement since you have to know well every money that goes out and goes in, it is just a matter of keeping records of your transactions may it be involved with incoming or outgoing money.
