How can I compare the cost of two specific points in time?

On the Market level and on the Mill level, Analytical Cornerstone allows the comparison of two quarters at a time (two quarters of any years). To do so:

• After selecting the initial Cost Date to compare with on the Cash Cost Curve,
• click on Compare Dates

• select the quarter to compare with from the Cost Date for Comparison dropdown
• hit Compare Dates

• The page refreshes, showing, by default, the Data-Comparison report. The “scenario data” (usually the older date) shows in yellow colour, whereas the first/more recent data shows in grey/yellow colour
• Note that there are several tabs with the data reports for both quarters, as well as the graph of both dates, plus a graphic comparison

When to change the Balance Date:

1. Change the Balance Date if you are looking to evaluate the effect of some specific process change or investment that happened since, or to included mills that were closed since.
2. Keep the latest available Balance Date if you want to compare the latest operational setup with different unit costs. It will keep the mill data consistent at the latest available status, and only change cost date.
