Frequently Asked Questions

Is Westlake Corporation (WLK) halal to invest in?
Westlake Corporation (WLK) is rated Not Halal under AAOIFI Standard 21 screening. It fails either the business activity screen (primary involvement in prohibited sectors such as conventional banking, alcohol, or gambling) or one of the quantitative financial ratio thresholds. Muslim investors should avoid or exit this position.
Why did Westlake Corporation get a F compliance rating?
Westlake Corporation (WLK) received a grade of F (Non-Compliant) based on three AAOIFI Standard 21 financial ratios: debt-to-market-cap of 51.7% (limit 30%); interest-bearing deposits of 27.1% (limit 30%); prohibited income of 1.02% (limit 5%). The grade reflects the margin of safety across all three ratios relative to their thresholds.
What could change Westlake Corporation's Shariah verdict?
Westlake Corporation's verdict is re-evaluated at each annual re-screen. Three events could change it: (1) the debt-to-market-cap ratio crossing 30%, typically from new debt issuance or a major drop in share price; (2) interest-bearing deposits exceeding 30% of market cap; or (3) prohibited revenue (alcohol, gambling, conventional finance, etc.) exceeding 5% of total revenue. Verdict flips are tracked in the compliance history section above.
