In a company, partnership, or sole proprietorship venture, its financial statement shows the financial well being or condition of the company. A balance sheet constitutes 3 basic aspects: assets, liabilities, and equity. Needless to say, for a company to be profitable, the liabilities need to be lesser than the assets. The difference in amount shows the 'net worth' of the company. If you are new to such sheets and wondering how it is done, you can search the internet for many sheet examples. A typical company statement of financial position presents assets and liabilities in 2 different sections and the total should always balance. If the sheet does not show the same amount in both assets and liabilities, it has to be redrawn.
Also, how long is your investment horizon? Is it really that important to you to project out to 30 years or is 3λ years sufficient along with a terminal value that represents the expected NPV beyond 5 years? Usually this latter approach works best and looks the most credible to potential investors. There are numerous ways to calculate terminal value including multiples, current market values projected forward, and round guesstimates. Obviously these decisions are affected by your personal preference and the type of investment for which you're calculating present value.
