Benefits of Purchasing Company Stock at a Discount
If your purchases are done at year end, but the money withheld over that 12 month period, the 17% return is for an average time of 6 months, and the return annualizes to 38% or so. All due respect to Alex B, the return would be 100/85 as he states, if the investment were funded in January and sold in December. But this isn't the case on ESPP, the average time you are out that money is 6 months.  I will warn you. Don't let the tax tail wag your investing dog. It's easy to wait for long term gains to kick in and then ignore the stock. You then find yourself overloaded on one stock and risk some bad losses. I enjoyed my 15% discount all the way to the stock crashing by 60%+. If you must wait and hold some, be religious about selling the long term shares like clockwork. The 15% is virtually risk free (unless the shares crash between purchase and hitting your account.)
