market_value = traded_price (price date) / depositary_ratio x latest point-in-time SEC shares outstanding (share-count date shown; from the filing cover page, summed across share classes only where the issuer filing verifies the classes are economically equivalent (rule + evidence URL in the source text), else withheld; priced at the primary listed class, so where other classes trade at a different price the value is an approximation; restated only for issuer-verified splits after the count date); weighted-average share counts are never used
