Peter Mellen - OPTIKA - M – company profile, ID number 33730385

Profit to net sales = profit after tax / net sales × 100. Net sales may not include all revenues, so we do not refer to this ratio as net profit margin. Equity ratio = equity / assets × 100; we keep negative values.

Median is the middle value; the middle 50% is the range between the first and third quartiles. We calculate the individual ratios of companies, not the ratio of totals. Missing values ​​and zero or negative denominators do not enter the given indicator. The minimum is 30 valid reports per indicator.

Source: saved RÚZ statements of the MUJ account type (687) and POD account (699), each type separately. Five previous years are available. The group also includes the evaluated company, if it was already saved at the time of the calculation. This is not an industry benchmark or a risk score. The coverage of RÚZ in our database is not complete; year is the year of the end of the statement and the length of the accounting period is not verified.
