How AAOIFI Halal Stock Screening Works

AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions) sets the global standard for Shariah-compliant equity screening. A stock passes AAOIFI screening if it meets 4 criteria: debt ratio below 33%, interest income below 5%, cash and interest-bearing securities below 33% of market cap, and the company's primary business activity is halal.

The 4 AAOIFI Screening Criteria

For a stock to be considered Shariah-compliant under AAOIFI standards, it must pass all four of the following financial and business activity screens:

Criterion Threshold What It Measures
1. Debt Ratio < 33% of market capitalization Total interest-bearing debt divided by the company's trailing 12-month average market cap. High debt levels mean the company relies heavily on interest-based financing, which is prohibited in Islamic finance.
2. Interest Income < 5% of total revenue Income earned from interest-bearing deposits, loans, or securities as a percentage of total revenue. Even halal companies may earn small amounts of interest from corporate cash management.
3. Cash & Securities < 33% of market capitalization Total cash and interest-bearing securities divided by market cap. Excessive cash held in interest-bearing instruments raises compliance concerns.
4. Business Activity Primary activity must be halal The company's core business must not involve prohibited activities: conventional banking/insurance, alcohol production, tobacco, gambling, pork products, weapons, or adult entertainment.

Understanding Each Criterion

Criterion 1: Debt Ratio (< 33%)

This is often the most impactful screen. Many companies use debt financing extensively, and interest-bearing debt is prohibited (riba) in Islamic finance. The 33% threshold acknowledges that most publicly traded companies carry some debt, but limits exposure to a minority position. Companies in capital-intensive industries (utilities, telecommunications, real estate) may struggle to meet this criterion.

Criterion 2: Interest Income (< 5%)

Even companies with entirely halal operations may earn incidental interest from corporate bank accounts or short-term investments. The 5% threshold allows for this reality while ensuring interest income remains a negligible portion of revenue. If a stock passes this screen but has some interest income, the corresponding portion of dividends should be purified (donated to charity) through the tatheer process.

Criterion 3: Cash and Interest-Bearing Securities (< 33%)

This criterion examines the asset side of the balance sheet. A company holding large amounts of cash in interest-bearing accounts or investing heavily in bonds and fixed-income securities is generating impermissible returns on a significant portion of its value. The 33% cap ensures the majority of the company's value comes from productive halal assets.

Criterion 4: Business Activity (Halal)

This is a qualitative screen. Companies whose primary business involves the following are automatically excluded, regardless of their financial ratios:

Status Categories

Based on the screening results, Rafiq assigns one of three compliance statuses:

Status Meaning Action
HALAL Passes all 4 AAOIFI criteria with comfortable margins Permissible to invest. Purify any non-compliant portion of dividends via tatheer.
NOT HALAL Fails one or more criteria significantly, or primary business is haram Not permissible to invest. If already holding, consult a scholar about divestment.
QUESTIONABLE Borderline on one or more ratios; scholars may differ Exercise caution. Review the exact ratios shown and consult your scholar.

What "Questionable" Really Means

A stock classified as QUESTIONABLE is not definitively halal or haram. It typically means the company is near a threshold on one or more criteria — for example, a debt ratio of 31% when the limit is 33%, or interest income at 4.5% when the limit is 5%. Different scholars and Shariah boards may reach different conclusions on borderline cases.

Rafiq shows the exact ratios for each criterion so you can see precisely where the company stands. This transparency allows you to make an informed decision in consultation with your own scholar or Shariah advisor.

Financial ratios also change quarterly as companies report new earnings. A stock that is borderline today may shift to clearly compliant or non-compliant after the next quarterly filing.
