expected answer:
Trade error rate (Q1-Q4 2025): Q1: 0.012%, Q2: 0.009%, Q3: 0.007%, Q4: 0.005%. Current Q4 rate of 0.005% is well below industry thresholds. Year-over-year improvement of 58% (0.012% in Q1 → 0.005% in Q4).

Net capital ratio (Q1-Q4 2025): Q1: 18.2%, Q2: 19.3%, Q3: 20.5%, Q4: 21.8%. Current ratio of 21.8% is comfortably above the SEC Rule 15c3-1 minimum of 15%. Ratio increased every quarter, demonstrating strengthening capital position.

Regulatory examination status: Zero material findings in the last 2 completed FINRA examinations (EX-0003: May 2024, EX-0007: Oct 2025). Note: A routine cycle exam is currently in progress for Q1 2026.
