Numbers, method and sources
Share of revenue per customer as tagged in the filing’s XBRL (ConcentrationRiskPercentage, benchmark revenue). US GAAP requires disclosure only for customers with at least 10% of revenue; a year without a customer means below 10% or not disclosed. Labels like “Customer A” are the filer’s own; the same label is not guaranteed to be the same customer every year.
