What makes a company halal to invest in?

Two main tests

When a company is assessed for Shariah-compliant investing, the process normally starts with two questions: what does the company do, and how is it financed?

Business activities

The company's main activities and sources of revenue are reviewed. Businesses centred on prohibited activities are excluded. A methodology may also set limits for small amounts of incidental revenue from non-compliant sources.

Financial screening

A company can have a permissible core business but still fail a Shariah screen because of its financial structure. Screening methodologies therefore examine selected financial ratios, commonly including measures connected with interest-bearing debt, cash or receivables.

Different recognised methodologies use different definitions, thresholds and denominators. That is why the same company may not receive the same result under every Shariah index or screening provider.

Screening is ongoing

Compliance is not necessarily permanent. A company's debt, revenue mix or business activities can change, and screening providers review companies periodically. An investment fund may therefore add or remove companies when its underlying Shariah methodology is updated.

There can also be legitimate scholarly differences between methodologies. Rather than treating a 'halal' label as universal, it is useful to understand which methodology and Shariah governance process is being used.
