In MasterPlan, Common Pool Assets include cash and securities assets. We call them Common Pool Assets because many of the data entry items (fields) such as the Per Share Value of a common stock is the same price on the same day for every person who owns that stock.
We keep these items in a "library" which we call the Common Pool. This means that every time you add a stock such as IBM to anyone on your database, MasterPlan will store the items that are common to everyone who owns that asset in the Common Pool for Stocks and display them on the client's stock window.
If an item (such as the Per Share Value) has changed, you can make the change right on the client's portfolio or in the Common Pool library window. We store the new value back into the Common Pool, so you have essentially updated the stock record for everyone who owns that stock.
The Common Pool greatly speeds up data entry time and makes editing these records a snap.
