FAQQuestions

What business area does Profit Equalization Reserve belong to?
Profit Equalization Reserve sits in the Deposits and Investment Accounts business area — Shariah-compliant deposit and investment accounts, where returns come from profit-sharing and safekeeping rather than interest. It follows the BIAN Manage functional pattern over the Profit Equalization Reserve asset, with the Profit Equalization Reserve Management Plan as its control record.
How is this isolated from conventional banking?
Completely. The Islamic landscape shares no code, repositories, namespaces or events with the conventional platform. This domain lives in the isb-deposits namespace with an isb-* repository and com.bank.islamic package, so the two can never mix by accident.
Is this a certified Shariah-compliant product?
No. It is an educational reference implementation in the BIAN service-domain style. Actual Shariah compliance of any real deployment requires certification by a qualified Shariah Supervisory Board. Standards referenced: AAOIFI, IFSB, IIFM.
