Cost - Price Graph

This graph overlays the share price (NAV) with the out of pocket cost for each share. This out of pocket cost can plot either the per share cost of the currently owned shares, or the historical per share cost for the investment. The menu command Graphs / Options / Historical Cost controls which type of cost is plotted. This graph allows you to see graphically the current price with the break even point.

The historical out of pocket cost is calculated by adding all purchases, subtracting all redemptions, and subtracting all received distributions. This sum is then divided by the total number of shares owned to obtain the out of pocket cost for each share. The purchases only include out of pocket purchases, not reinvested distributions. The received distributions only include distributions paid to the investor in cash, not reinvested distributions. This cost is not the same as the tax basis cost, but shows the break even point for the full history of your investment. The historical out of pocket cost is calculated with the formula:

The current out of pocket cost is calculated by adding up the cost to purchase all the currently owned shares, and subtracting off any received distributions from the currently owned shares. The first in first out method is used for determining this cost. This sum is then divided by the total number of shares owned to obtain the out of pocket cost for each currently owned share. The purchases only include out of pocket purchases, not reinvested distributions. The received distributions only include distributions paid to you, not reinvested distributions. This calculation shows the break even price point on the remaining balance of shares currently held. The current out of pocket cost is calculated with the formula:

The vertical axis is price and cost. The horizontal axis displays the date. If auto scaling is on the vertical axis automatically scales to cover from the minimum to the maximum achieved during the displayed period. The top vertical axis label will specify the maximum, and the bottom vertical axis label will specify the minimum achieved during the displayed period.

The graph will be labeled with **CST-NAV-H** or **CST-NAV-C** to stand
for Cost - NAV in either historical (**-H**) or current (**-C**) cost
mode. The ending share price displayed on the legend will be labeled with the
current currency symbol of the investment. The ending out of pocket cost will be
labeled with **C:** (Cost). The change in these values from the previous day
is also displayed in parenthesis.

If the yields are turned on (View / Yields) they will be displayed above the graphs. See Yield Calculations for information on the reported yields.

**Comments:** The out of pocket share cost only changes after a purchase,
redemption, or any distribution. (A reinvested distribution increases the number
of shares owned and a received distribution decreases the amount invested.) The
historical cost may actually go negative if you have redemptions plus received
distributions totaling more than the sum of all purchases.
