Industrial Organic Chemicals — 같은 업종, 그리고 규모가 비슷한 기업Industrial Organic Chemicals — and other companies of a similar size

SEC가 같은 업종(Industrial Organic Chemicals)으로 분류한 기업이 먼저 오고, 그다음은 제출된 매출로 가까운 순입니다 — 가장 최근 연간 값이며, 연간 값이 없으면 최근 네 분기 합입니다. Companies the SEC assigns to the same industry (Industrial Organic Chemicals) come first, then the nearest by revenue as filed — the latest annual figure, or the last four quarters where no annual one is filed. 순서일 뿐 값이 싸거나 비싸다는 뜻이 아닙니다.Order only — it does not say a company is cheap or expensive.
