RatioInterest-bearing loans / total assets

Debts proven not to count (line 6J 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. Of the lease liabilities shown on the balance sheet, TRY 194,690,016 are debts that do not count under TKBB Guideline 6.2, so they were deducted from the debt numerator (source: balance sheet, page 4). For the other lease liabilities on the balance sheet (TRY 229,212,945), the breakdown in the notes was used. The ratio rests on the items read from the financial statements; the statements will be read again. Note 8: “Kiralama işlemlerinden uzun vadeli borçlanmaların kısa vadeli kısmı” TRY 229,212,945: not counted (proven). Note 8: “vadeli kısmı” TRY 194,690,016: undetermined, kept in the numerator. Notes that could not be used: Other payables: no note was found for this item (condensed interim report). On the items read, the measured range is 0.00% to 0.93%.

Calculation and source

Calculation: numerator ÷ denominatorTRY 4,237,476÷TRY 845,216,732 (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.

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. 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. Note 19: “Kira gelirleri” TRY 2,502,201: not counted (proven); “Vade farkı geliri” TRY 1,863,108: not counted (proven); “Kambiyo karları” TRY 476,172: not counted (proven); “Hurda ve malzeme satış gelirleri” TRY 205,028: not counted (proven); “Ticari borç reeskont geliri” TRY 0: undetermined, kept in the numerator; “Diğer” TRY 4,117,815: undetermined, kept in the numerator.

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. The ratio rests on the items read; the statements will be read again, so the ratio and the amount may change. On the items read, the measured range is 0.01% to 0.50%; the purification amount is calculated with the 0.50% found from the items read.

  • 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.
