Salam,
I plan to use the AAOIFI purification method. I understand how to make the calculation. The problem I have is what numbers do I use? Are those percentages of non-complaint revenues based on the last fiscal year data? The problem is that there is usually a lag in the time of the fiscal year ending and the time the report is filed, often months. The other issue is that the number of outstanding shares varies from month to month. The other problem is each company chooses its own fiscal year. What is a simplified approach to doing this calculation? I think the lack of automated calculation is the achilles heal of this app. Those using Zoya are already concerned about halal/haram, so the app should go all the way and actually make these calculations for us. I have too many stocks to make this practical by hand. JAK
