A principled approach to the markets — screening companies for ethical business conduct, financial integrity, and social responsibility using AAOIFI's internationally recognized standards.
AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions) publishes internationally recognized financial screening standards used by institutions worldwide. Their quantitative thresholds — covering debt ratios, revenue purity, and business activity — provide a disciplined framework that aligns naturally with broad ethical investing principles.
Companies whose core business involves excluded sectors are removed entirely — regardless of their financial ratios. This is the broadest filter and removes the majority of ethically problematic companies.
Even permitted businesses sometimes derive incidental revenue from excluded sources. AAOIFI sets a 5% threshold for impermissible revenue — companies exceeding this are excluded or flagged.
Companies with total debt exceeding 33% of total assets are considered over-leveraged under AAOIFI standards. Excessive leverage introduces financial risk and interest dependency that conflicts with principled investing.
Interest income must remain below 5% of total revenue. This limits exposure to companies that are functionally dependent on interest-bearing financial activity, even if their core business is permitted.
Financial ratios change every quarter. Nucore re-screens the entire universe daily using updated data feeds, ensuring no stock slips through a filter due to stale financial information.
Every screening decision is logged with the exact factor values that produced it. You can inspect why any stock passed or failed — no arbitrary decisions.
Some investments in the ethical universe may generate small amounts of incidental impermissible income. Our charitable allocation tool calculates the recommended amount to donate, helping investors maintain the integrity of their portfolio returns.
Based on each company's impermissible revenue percentage and your holding size, Nucore calculates the proportional recommended charitable allocation from your returns.
This amount is logged in your dashboard. You choose where to donate — Nucore simply provides the calculation and tracking.
True ethical investing isn't just about what you hold — it's about what you do with proceeds from imperfect holdings. Our tool brings the same analytical rigor to charitable giving that we bring to stock screening.
All charitable allocation history is exportable for your records.
