Income statement data need adjustment to become quarterly information

[dkgaraujo]

Banco Central do Brasil's IF.Data originally presents bank income statement accounts cumulatively in each semester: the values for the second and fourth quarters also contain the income and expenses of the first and third quarters, respectively.

Ideally brazilianbanks should offer users a quarterly income statement, whereby the values for each quarter only represent amounts earned or expensed during that period, with the option to retain the income data on a semester basis as originally reported.
