Data sources and calculation methods

Primary source: the annual securities report of Perseus Proteomics Inc. on EDINET, the FSA’s disclosure system (free to read)
Corporate number: 1013201011111 / Accounting standard: Japanese GAAP

  • Amounts: machine transcription of EDINET XBRL (no manual re-keying). Long narrative notes are text and not in the account list. Identifiers: machine transcription of the EDINET code list (retrieved 2026-08-22)
  • ★: position of the value calculated from disclosed figures among the 4,240 companies on this site, on a five-step scale. Not a judgement of the company. No forecasts usedThe formulas and how they are counted
  • No rank: net assets as a share of total assets, cash conversion and revenue per employee (size alone does not show quality). Industry median shown for comparison. Cash conversion of 100%: operating cash flow equal to operating profit
  • Profit-and-loss chart: only where “sales − cost of sales − SG&A = operating income” holds between disclosed values. Cost breakdown: the six largest SG&A items
  • Trend charts: key financial indicators of the annual securities report. Amounts in billions of yen (dividend per share in yen). Long-run chart joins reports filed in different years (newer report for overlapping years). Some items stop part-way after a change of accounting standard. A stock split changes the weight of one share. Consolidated and parent-only in separate tables
  • Revenue scale in the same industry: bars of revenue (disclosed values) of companies in the same industry grouping as the industry pages, largest first. Only the top three and the two companies either side of this one. Each company’s latest fiscal year. An order of size, not a ranking of quality or an investment view
  • Share prices: not published (no data source allows redistribution). No share-price-based indicators (such as the price earnings ratio) and no extension of past growth into the future
  • Average age, average length of service and average annual salary: the reporting company alone (the parent). At a holding company, a small head-office staff. Payout ratio (basic facts): dividend per share ÷ consolidated earnings per share, calculated here (the payout ratio in the annual securities report is the reporting company’s figure, on a different basis). Representative and founding date: gBizINFO (Ministry of Economy, Trade and Industry), some companies only
  • “Retrieved disclosed figures”: every value readable as a number from the annual securities report. Company-wide values only (no segment or other breakdowns)
  • Segment table: machine transcription of the segment information in the annual securities report. Business names as labelled by the company in its XBRL. No table where segment sales differ from the disclosed total by more than 1%. Adjustments, corporate, eliminations and “other” left out of the table and the share denominator, as they are not businesses
  • Breakdowns of amounts, not diagrams of how the business works. Who pays whom, and for what, is not in the disclosed figures; no lines drawn from guesswork
