* Shares, change to shares, sold shares, shares held after: split-adjusted.
* Reported price: this doesn't represent the actual buy or sell price. It is the split-adjusted price of the security as of the last day of the reported period.
* Current price: this can be a delayed price and may not reflect the real-time market value, however it is too close.
* Value or Price: If the security is completely sold out, we show the reported value (or price) prior to the actual period.
* Held since / Held for: calculated since the latest "new buy" position. If the security was previously exited and re-entered, only the most recent holding period is counted. 2013 Q2 is the earliest period we have data for, so "2013 Q2*" means "2013 Q2 or earlier".
