The reading of the excluded income ratio in the financial statements for the period ending June 2026 is not complete; the ratio rests on the items read. The statements will be read again, and the record's result will be given after that.

This is a measurement, not a religious ruling.

Calculation and source

Calculation: numerator ÷ denominatorTRY 4,969,072,573÷TRY 12,001,386,783 (total assets)× 100

RatioInterest-bearing loans / total assets

The measurement is a range. The lower bound counts only the amounts that the statements and notes prove; the upper bound also counts, as a precaution, every item that could not be proven. The threshold falls inside this range, so the outcome depends on the company's KAFİF declaration.

Upper bound. Debt items that may count as interest-bearing (line 6I of the KAFİF form) were taken in full from the public statements. Of the lease liabilities shown on the balance sheet, TRY 140,280,032 are debts that do not count under TKBB Guideline 6.2, so they were deducted from the debt numerator (source: balance sheet, page 4). Deductions on line 6J of the company's KAFİF declaration are taken only when the financial statements or notes confirm them. The ratio is therefore an upper bound for the items shown in the financial statements. (Loans from participation banks and lease certificates (sukuk) are deducted only when a note shows them separately; none of them was deducted in this measurement.) Notes that could not be used: Note 6 (Other payables): the item's table was not found in the note. Note 4 (Short-term borrowings): the columns of the note's table could not be read reliably. Note 4 (Long-term borrowings): the columns of the note's table could not be read reliably. There is no usable evidence from the notes, so the proven amount was set to 0 and the lower bound is 0%. The ratio is in the range 0.00% to 41.40%; the outcome depends on the company's declaration.

Upper bound

Calculation and source

Calculation: numerator ÷ denominatorTRY 186,216,918÷TRY 12,001,386,783 (total assets)× 100

RatioInterest-bearing cash and securities / total assets

Upper bound. Asset items that may count as interest-bearing (line 5F of the KAFİF form) were taken in full from the public statements. Assets proven not to count (line 5G of the KAFİF form) were deducted as far as the notes prove them; items that could not be separated stayed in the numerator, as a precaution. The ratio is therefore an upper bound for the items shown in the financial statements. Note 3: “Vadesiz mevduat” TRY 520,837,137: not counted (proven); “Vadeli mevduat” TRY 178,000,000: counted in the ratio (proven); “Diğer hazır değerler” TRY 7,576,314: undetermined, kept in the upper bound. Notes that could not be used: Financial investments (current and non-current): no note was found for this item (condensed interim report). The ratio is in the range 1.48% to 1.55%; both bounds give the same result.

Measured on the items read

Calculation and source

Calculation: numerator ÷ denominatorTRY 0÷TRY 5,591,041,120 (total income)× 100

RatioExcluded income / total income

On the KAP form this item is titled “Katılım Finans İlkelerine Uygun Olmayan Gelir”, which means income not in line with participation finance principles.

The deduction for income that does not count (line 4D of the KAFİF form) is not known and was set to 0. The ratio rests on the items read from the financial statements; the statements will be read again. Excluded income from business activities (line 4B of the KAFİF form) does not appear in the financial statements; it is only in the company's KAFİF declaration on KAP. This measurement sets it to 0. If there is a declaration, the record shows it separately, with a link. The notes were not part of this read, so the proven amount was set to 0. On the items read, the measured ratio is 0.00%.

The three ratios are calculated from the financial statements, and each bar is scaled to its own threshold. The measurement uses the company's latest published statements, and every record states the period. The official review uses audited six- and twelve-month statements (Standard 3.4), so the periods can differ. Method

This record is produced by Sağlama's calculation from the financial statements the company publishes. The method and the corrections log are public. Responsible for this record: Savaş Tutumlu, founder.

What this measurement covers

This record's financial statements will be read again. The ratios rest on the items read; the record's result will be given after the new reading. Method

The company's KAFİF declaration

The company's declaration on the KAP form (full year 2025): excluded income 0.0%, interest-bearing assets 0.9%, interest-bearing loans 33.5%. The company's own declaration puts at least one ratio above the threshold, but within the tolerance band. The rules allow a wait of one period; if the previous review also found a ratio above the threshold, the member leaves. View the form on KAP Review forecast

Purification calculation

Dividend-based method · CALCULATOR (DIVIDEND-BASED METHOD)

Purification calculator

A company within the threshold can still have a small amount of excluded income (interest income and other income the standard excludes). Under the TKBB standard, the part of this income that falls to your shares is given to charitable causes. This duty applies whether the company made a profit or a loss, and whether or not it paid a dividend. The amount set aside does not replace zakat or sadaqa.

Purification amount = gross dividend × excluded income ratio

The number of shares and the dividend are sample inputs. The ratio comes from the company's measurement. To calculate with your own figures, use the purification page.

Purification amount = gross dividend × excluded income ratio (dividend-based method). Under TKBB Standard 3.6.1, purification is needed even if the company makes a loss or pays no dividend. The method page quotes TKBB Standard 3.6, including the inflation deduction under 3.6.2. The ratio rests on the items read; the statements will be read again, so the ratio and the amount may change.

  • Excluded income is the part of a company's earnings that is not in line with participation finance principles. On the KAP form it is called “income not in line with participation finance principles.”
  • Purification is done even if the company makes a loss.
  • Purification is needed even if no dividend is paid. The calculation here uses the dividend-based method. TKBB Standard 3.6 also counts how long you held the shares (the share-days method), which this calculator does not do yet.
  • The purification amount does not replace zakat or sadaqa. Under the TKBB standard, it is given away, not kept.
  • You give the amount yourself, to a charitable cause of your choice. Sağlama does not direct donations.

This calculation uses the dividend-based method. TKBB Standard 3.6 also counts how long you held the shares (the share-days method). The standard is quoted on the method page.
