Find a stock split and create and describe a scenario of your investment (when did you originally purchase and how many shares at what price, what did the stock split do to your investment, where there any tax consequences).

Why did the company split their stock and what happened since then to the valuation? Did you sell you stock, if so when at what price and where there any tax consequences? As always, pick a stock you are interested in, and it doesn't have to be a US stock.
