| Earnings Per Share [Text Block] | 12. SHARES AND PREFERRED SHARES Ordinary Shares In connection with the Redomiciliation, STERIS UK shareholders received STERIS plc shares pursuant to a scheme of arrangement under UK law. Each STERIS UK ordinary shareholder received one ordinary share, par value $75.00, of STERIS plc for each STERIS UK ordinary share held, which STERIS UK shares were canceled. On May 3, 2019, the par value of STERIS plc shares issued pursuit to the scheme of arrangement was reduced to $0.001 per share. We calculate basic earnings per share based upon the weighted average number of shares outstanding. We calculate diluted earnings per share based upon the weighted average number of shares outstanding plus the dilutive effect of share equivalents calculated using the treasury stock method. The following is a summary of shares and share equivalents outstanding used in the calculations of basic and diluted earnings per share:

Additional Authorized Shares The Company has an additional authorized share capital of 50,000,000 preferred shares of $0.001 par value each, plus 25,000 deferred ordinary shares of €1.00 par value each, in order to satisfy minimum statutory capital requirements for all Irish public limited companies.
