# Reading simulation results

Select a scenario or portfolio and CRQ Pro simulates it automatically, filling the **Results dock** at the bottom of the Scenarios page. Results re-run on their own whenever you change inputs, appetite, or the iteration setting (you will briefly see "Updating…"), and there is a **Re-run** button for manual runs.

Simulations use a fixed random seed, so the same inputs always produce the same results.

## Summary statistics

| Statistic                      | Meaning                                                                                                        |
| ------------------------------ | -------------------------------------------------------------------------------------------------------------- |
| **Expected Annual Loss (ALE)** | The mean of the annual loss distribution. The long-run average yearly cost.                                    |
| **Median (P50)**               | Half of simulated years lose less than this, half lose more. Often far below the mean for skewed cyber losses. |
| **P90**                        | A 1-in-10-year loss level.                                                                                     |
| **95% VaR**                    | A 1-in-20-year loss level (95th percentile).                                                                   |
| **P99**                        | A 1-in-100-year loss level.                                                                                    |
| **Max simulated**              | The single worst year in the run. Indicative only; it moves with iteration count.                              |
| **P(any loss / yr)**           | The share of simulated years with at least one loss event.                                                     |

A **risk rating badge** (Low, Moderate, High, or Critical) shows how the rated statistic compares to your [risk appetite](/crq-pro/guides/risk-appetite.md).

## Tabs

* **Scenario**: details of the selected item.
* **Taxonomy**: factor sensitivity for a single scenario, showing which parts of the model drive the result.
* **Stats**: expected values per factor for a single scenario.
* **Loss Exceedance**: the LEC plots, for each loss amount, the probability that annual losses exceed it. Read it as "there is a 5% chance of losing more than X in a year." Exportable as CSV or PNG.
* **Histogram**: the shape of the annual loss distribution. Exportable as CSV or PNG.
* **Simulations**: the raw per-run table, one row per simulated year, sortable, with per-run exceedance percent. Drilling into a single scenario also shows the realized event count (LEF) and per-event loss. The full table can be exported to CSV.
* **Contributors** (portfolios): ranks member scenarios by contribution to the mean and to the tail.

## Iteration count

**Settings > Application > Simulation > Default iterations** sets the trials per simulation: 10,000, 50,000 (default), 100,000, or 250,000. Higher is more precise, especially in the tail (P99 and beyond), but slower. 50,000 is a good working default; bump it for final numbers going into a report.
