Both report in USD. Amounts are as filed, not converted.

Why this pair: same peer group, revenue within 4x in the same currency. Peer groups are curated by hand from each company's business as described in its own 10-K/20-F (what it sells, not its SIC code). A company can sit in more than one group. Within a group, a pair is listed when both companies report in the same currency and the larger company's latest fiscal-year revenue is at most 4x the smaller one's; each company keeps its 4 nearest peers by revenue ratio. Companies reporting in different currencies are never size-matched (amounts are not converted); a short list of obvious same-industry pairs across currencies is added by hand, with the reason, as are two direct competitor pairs outside the size rule (AMD vs NVIDIA, Intel vs NVIDIA).
