What happens if a company or fund stops being Shariah compliant?

The holding is normally identified at the next screening review and disposed of within a defined window, with any tainted gain purified.

The exact treatment depends on the fund's methodology and certificate, but the pattern is consistent: periodic re-screening, a disposal period once a breach is found, purification of the non-compliant portion of income or gain, and disclosure in the fund's reporting.

For a fund as a whole, losing certification is a more serious event - it may be re-screened, restructured, or cease to be described as compliant. The fund's own disclosure is the authority on what happened and when.
