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.
Index / note cards _ I organize my thoughts by creating slides in "thumbnail view". I select a slide, type my thoughts, and add any visualizations I want. With PowerPoint in "thumbnail view", I move slides around as if they are index cards as I organize my thoughts. Add / delete slides as appropriate. Then print all slides as 6 or 9 slides/per page to have a printout of the "note cards". Give PowerPoint a second look and see if you can use it as an idea visualization tool. Love it rather than leave it and you just might convey your thoughts and organize your messages more effectively.cle Source: http://EzineArticles.com
