This slide presents an IBCS compliant Z chart showing ORLEN’s quarterly EBITDA LIFO together with the Moving Annual Total. The redesign highlights how short term volatility contrasts with the stable long term trend, making the +12% MAT increase easy to see at a glance. By structuring the data clearly and reducing visual noise, the chart helps the viewer understand the relationship between quarterly fluctuations and overall performance.
