This is a measurement, not a religious ruling.

MEASUREMENT TABLE

Interest-bearing loans

21.4%

Upper bound

Calculation and source

Calculation: numerator ÷ denominatorTRY 293,486,376÷TRY 1,374,801,373 (total assets)× 100

RatioInterest-bearing loans / total assets

Upper bound. TRY 4,770,371 that is proven not to count was deducted from the debt numerator (source: Note 9). As a precaution, financial liabilities other than leases shown on separate lines outside the main debt total were added once, after they were confirmed against their section total. This is an assumption: it is not proven that these items carry interest. Because extra items are included, the ratio is an upper bound for the items shown in the financial statements. Note 9: “Banka Kredileri” TRY 261,908,950: undetermined, kept in the upper bound. Note 9: “Kiralama İşlemlerinden Borçlanmalar” TRY 4,770,371: not counted (proven). Notes that could not be used: Note 6-13 (Other payables): no note was found for this item. The ratio is in the range 0.00% to 21.35%; both bounds give the same result.

Interest-bearing assets

6.6%

Upper bound

Calculation and source

Calculation: numerator ÷ denominatorTRY 89,991,845÷TRY 1,374,801,373 (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 8: “Yatırım Fonları(*)” TRY 3,984,882: undetermined, kept in the upper bound; “Vadesi 3 Aydan Uzun Vadeli Mevduatlar” TRY 9,097,669: counted in the ratio (proven).

The ratio is in the range 6.26% to 6.55%; both bounds give the same result.

Excluded income

within the threshold
3.8%

Measured on the items we can calculate

Calculation and source

Calculation: numerator ÷ denominatorTRY 19,625,029÷TRY 523,890,044 (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.

Measured on the items we can calculate. Income items that may count as excluded (line 4C of the KAFİF form) were taken in full from the public statements. Income that the notes prove does not count (line 4D of the KAFİF form) was deducted. Items that could not be separated stayed in the numerator, as a precaution. For these income lines (line 4C), the ratio is an upper bound. 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. Note 35: “Faal. Kayn. Kur Farkı Geliri” TRY 7,684,992: not counted (proven); “Konusu Kalmayan Karşılıklar” TRY 2,429: not counted (proven); “Teşvik Gelirleri” TRY 2,126,222: not counted (proven); “Diğer Gelirler” TRY 4,331,234: undetermined, kept in the upper bound. Note 38: “Faiz Gelirleri” TRY 14,946,687: counted in the ratio (proven); “Kur Farkı Geliri” TRY 3,797,831: not counted (proven). Note 36: “Finansal Yat Satış ve Değ. Karları” TRY 347,108: undetermined, kept in the upper bound. The ratio is in the range 2.85% to 3.75%; both bounds give the same result.

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.

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. This is a cautious calculation. The amount may be higher than the true figure, because it uses all of the interest income, not only the part above inflation. The ratio is the upper bound of the measurement (the lower bound is 2.85%); the purification amount is calculated on the upper bound, as a precaution.

  • 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.
