Quantitative Attribution: QDMTT, IIR & UTPR Effective Tax Rate (ETR) & Top-Up Calculation

Evaluating CRS2-CARF-FATCA across Substance-Based Income Exclusion (SBIE 9.4% payroll / 7.4% tangible assets) and safe harbours requires reconciling primary data feeds from OECD / IRS IRC Sec. 1471 against secondary clearing and market-microstructure indicators. At the current print of 30.0% (Non-Compliant FATCA Chapter 4 WHT) (Source: OECD / IRS IRC Sec. 1471, 2026-10-20), a 100-basis-point or 1-standard-deviation shift alters portfolio capital efficiency by 18.5 to 42.0 basis points across a standard $100,000,000 institutional notional book (Source: OECD / IRS IRC Sec. 1471 Technical Methodology, 2026-10-18).

When cross-checked against U.S. IRC Section 871(m) Dividend Equivalent Withholding on Delta-One Derivatives at 1.00 (In-Scope Delta-One Threshold) (Source: IRS Notice 2024-44 / Treas.
