Methodology / AAOIFI
AAOIFI Shari'ah Standard No. 21
PrimaryAAOIFI — as Akinda applies it. The standard Akinda's own verdict follows. Every status, rating and ratio elsewhere on Akinda is this one.
Who writes it
Owner of the standard
AAOIFI writes and maintains this methodology.
Akinda is not affiliated with them and does not use their screening data. What Akinda applies is their published financial ratios, recomputed on Akinda's own extracted filings.
The screens
Screening rules
Every ratio below is measured against 12-quarter average market cap. The comparator matters: this methodology's own wording is reproduced exactly, so a < is not silently read as a ≤.
Non-compliant income
Rule
prohibited income (interest + prohibited) > 5% → NOT HALAL; impure income (including half-weighted doubtful) > 5% → DOUBTFUL
Variables: interest income + revenue from prohibited segments. Doubtful revenue is counted at half weight, which is what separates a DOUBTFUL verdict from a NOT HALAL one.
Field on the API: non_compliant_revenue_perc
Debt
Rule
(short-term + long-term debt) ÷ 12-quarter average market cap — fails at ≥ 30%
Variables: short-term debt + long-term debt + capital lease obligations. Operating liabilities (e.g. payables) are excluded when they do not bear interest.
Field on the API: debt_ratio_perc
Cash / liquidity
Rule
(cash + short-term investments) ÷ 12-quarter average market cap — fails at ≥ 30%
Variables: cash & cash equivalents + short-term investments (interest-bearing cash equivalents, money-market holdings, short-term marketable securities). Receivables can optionally be included as a stricter mode — disabled by default to match AAOIFI Standard 21.
Field on the API: liquidity_ratio_perc
Business activity
What this methodology excludes
The base list: conventional banks and regional banks, mortgage lenders, asset managers, stock and securities exchanges, derivatives dealers and clearing houses, insurance and life insurance, healthcare plans, tobacco, alcohol (brewers, distillers, vintners), gambling and casinos, and pork / non-halal meat.
Preferred shares and fixed-income instruments are excluded by instrument, whatever the company does.

Re-screened
On every new audited statement — Akinda re-screens nightly
Scope
What this screen covers
Akinda computes the ratios above, nightly, on its own extracted filings. Three boundaries are worth stating plainly:
- Index buffers and grace periods are not applied. This methodology publishes none.
- The business classification is Akinda's own, built from company filings — not the provider's dataset.
- Index membership, index weights and purification amounts are the index owner's to publish, not Akinda's.
Detail
Worth knowing
No averaging window is written into the standard. Akinda uses a 12-quarter average market cap, and says so rather than leaving it implied.
The doubtful category and its half-weighting are an Akinda convention that follows AAOIFI. The four index methodologies have no doubtful state — their result is pass or fail.
What this page is, and is not
Akinda applies each methodology's published financial ratios. The business-activity classification is Akinda's own, built from company filings. It is not the index provider's own screening data. Akinda is not affiliated with, endorsed by, or licensed by AAOIFI, S&P Dow Jones Indices, FTSE Russell, MSCI or Yasaar.
These are raw-ratio verdicts, computed as if the stock were screened today. Index buffers and grace periods are not applied. A verdict here can therefore differ from a company's actual membership of an index.
AAOIFI is Akinda's primary methodology. The status, rating and ratios shown everywhere else on Akinda are AAOIFI.
The other four methodologies
Every screen Akinda runs, side by side, with the AAOIFI verdict the rest of the product publishes.
