How to Account for Angel Investments:
When your request is approved, you will receive a deposit of funds in your bank account. This amount should be recorded in the cash journal as a cash receipt and reflected in the cash budget as an "other cash receipt". It should also be reflected in the balance sheet (added to Assets: Cash, and added to Stockholder’s Equity: Common Stock).
For New Firms:
This amount of money becomes the value of your Common Stock (for example, if you are given a $200,000 equity investment: you will have issued 20,000 shares of common stock at a $10 par value for a total value of $200,000).
For Existing Firms:
You will simply add this as additional shares of Common Stock (for example, your balance sheet from last year shows $90,000 of common stock and you were given a $200,000 equity investment: the value of your common stock is now $290,000 and you will have issued an additional 20,000 shares at a $10 par value for a total of 29,000 shares of common stock outstanding at a total value of $290,000).
