Preclinical research with animal testing raising ethical concerns.
What You Should Know

Debt/assets is 34.45%, above the examined FTSE, MSCI and Malaysia asset limits; disclosed interest income is 0.10% of revenue. While supporting drug development is permissible, extensive animal testing raises Islamic ethical concerns.

Business-activity disclosure
Charles River provides preclinical research services, laboratory models and related products for drug development. The activity supports healthcare research, but extensive animal testing creates a material ethical question for Islamic investors.
Limitation: The filing does not allocate revenue into a scholar-approved prohibited-activity numerator for animal breeding, testing, product supply or customer end uses.
Purification
Charles River discloses $1.033 million of interest income but does not provide a scholar-approved purification percentage or a complete prohibited-activity numerator.
Inputs, assumptions and primary sources

- The filing does not quantify a universal prohibited-activity revenue numerator for animal research, product supply or customer end uses.
This is a reproducible financial screen, not a fatwa. A failed total-assets screen can coexist with a pass under a market-cap methodology. ZakatInvest keeps the qualitative assessment separate so numerical thresholds do not erase material context.
