Profit sharing introduction
Profit sharing in Mambu is an implementation of Islamic banking in the form of deposit products made up of Shari'ah law-based contracts. The principles of Islam, expressed by Shari'ah law, provide the foundation and the contracts built on these principles provide the structure for financial products. Mambu offers a foundation to support Islamic funding deposit-based contracts.
Principles of Islamic banking
The basic principles that all Shari'ah-compliant products adhere to are:
- Shari'ah-based: Operating on Shari'ah principles, which prohibit the charging or payment of interest (riba)
- Prohibition of interest: Charging, collecting, or paying interest within financial contracts is strictly prohibited.
- Asset-backed financing: Transactions are real asset based. Due to existence of goods and services no expansion of money takes place and thus no inflation is created.
- Profit or loss sharing: Financial contracts ensure the equitable sharing of profits or losses among participants.
- Avoidance of Haram transactions: Transactions involving forbidden (haram) products are strictly forbidden.
- Transparency and ethical considerations: Islamic banks often emphasise ethical and socially responsible investments. They ensure transparency and adherence to Shari'ah principles.
- Zakat and charity: Islamic banks offer accounts and products that facilitate Zakat (Islamic almsgiving) payments. They may encourage charitable giving as part of their operations.
- Contractual framework: specialised contracts, such as Mudarabah (profit-sharing), Murabaha (cost-plus-profit sale), Ijara (leasing), and more, which comply with Shari'ah principles are used.
Profit sharing process
There are three key stages:
- Profit calculation - to get a final equivalent profit rate for the Pool.
- Profit Approval (currently unavailable)
- Profit distribution (currently unavailable)
The diagram below outlines the key parameters involved in profit calculation:
- Income & expenses: Represent the profit for the investment period and can be allocated across multiple Pools based on specific allocation methods.
- Pools: Used to define the profit calculation frequency, the number of days in a month and year, and the type of balance used for calculating the average balance during the investment period.
- Product: Manages the weighting of accounts within a Pool. The daily profits are applied, and the percentages are shared between the customer and the bank.
