Share of revenue per customer, as the filing states it. 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.

Source: the filing’s tagged data (XBRL ConcentrationRiskPercentage, benchmark revenue), or the filing text where a share is not tagged.
