Sharia screening

Sharia screening is the process that decides whether a listed company is permissible to own. It runs in two layers. The first asks what the business does: a company earning its living from something impermissible is excluded outright, regardless of how well it is run. The second asks what its balance sheet looks like: even a company in a permissible line of business can fail if it is financed largely by interest-bearing debt or if too much of its income comes from interest. Both layers have to pass. A screened index or fund is simply the list of companies that survived both, re-checked on a fixed schedule.

The activity layer excludes conventional banking, insurance and brokerage, alcohol, tobacco, pork-related food, gambling, adult entertainment, and weapons. Some standards also exclude parts of hospitality and entertainment. The exclusion that changes a portfolio most is conventional financials, because interest is the core of what a conventional bank sells. Banks and insurers make up a large share of most broad indices, so removing them leaves a visible hole and pushes the remaining weight towards technology, healthcare and industrials. Almost every difference between a screened fund and its parent index traces back to this one exclusion rather than to the smaller ones.

The financial layer is three ratios plus an income test. Interest-bearing debt, cash and interest-bearing securities, and accounts receivable are each measured against a denominator and capped. In broad terms the debt and cash limits sit near a third, and the receivables limit somewhat higher, with the exact numbers set by whichever standard the fund follows. Separately, income from non-permissible sources is capped at a small share of total revenue, usually around five percent. What matters as much as the numbers is the denominator: some standards measure against total assets, others against a trailing average of market capitalisation. The same company can therefore pass one screen and fail another without anything about the company changing, which is why two funds that both describe themselves as compliant can hold different names.

Two things follow from all of this. First, compliance is a status, not a property: screens are re-run quarterly or semi-annually, and a company that leans harder on debt in one year can drop out at the next review. Second, screening reduces impermissible income but rarely eliminates it, which is where purification comes in. Most screened funds publish a purification ratio: the portion of income treated as non-permissible, which the holder is expected to give away rather than keep. Purification is not the same thing as zakat, which is a separate obligation on wealth and is calculated differently depending on whether shares are held to trade or to hold for the long term. Both remain the investor's responsibility; a fund can compute the ratio, but only the investor can act on it.

For a Gulf household, the practical problem is that most of the world's investable equity sits in markets that were never screened. The US alone is well over half of global market capitalisation, and its broad indices are led by exactly the conventional financials that the activity layer excludes. That leaves three routes: hold a screened fund and accept a different sector mix, screen individual companies yourself and accept the research burden, or stay in cash and deposits and accept that purchasing power erodes. The first route is what most people can actually sustain, which is why understanding what the screens do is worth more than memorising the thresholds.

Three threads pull this together. First, a screened equity fund is still an ETF with all the usual mechanics, so the ordinary questions about cost and structure still apply, and screened funds carry a visibly higher expense ratio than unscreened ones. Second, the screens shape the equity side only; the fixed-income side of an asset allocation is where sukuk do the work that conventional bonds cannot, and the bonds versus stocks distinction still governs how much of each you hold. Third, because screening removes conventional financials, a screened portfolio is more concentrated than its headline company count suggests, and that concentration is the real risk to manage rather than the screening itself.
