Person-Years of employment for an employer are estimated by dividing the employer's payroll by the average wage rate for the industry the employer operates in.  The assumption being made is that wage rates are the same for all employers in the industry.  For example, a person year is equivalent to one person working fulltime at an occupation for a one year period.
Serious Claims include all Non-HCO claims first-paid in the month of injury or in the following three months which also meet at least one of the following criteria: 28 or more days of wage loss in the period; health care costs equivalent to 28 or more days of wage loss; a fatality; one of 275 ICD9 serious codes.
Serious Injury Rate represents the serious injury claims per 1,000 Person Years. (Derived from # ICD9 Serious Injury Claims and # Person Years).
STD (Short-term Disability) Duration represents an estimate of the average number of STD Days paid for each STD claim.  It is calculated according to the methodology developed by the Association of Workers' Compensation Boards of Canada (AWCBC), and is based on all STD days paid in the year including days lost on injuries that occurred prior to the start of the 12-month period.  Days arising from rehabilitation payments are excluded from the calculation.
STD/LTD/Fatal claims refers to the number of short-term disability, long-term disability, and fatal claims accepted in the year (for all years of injury).  It does not include health-care-only claims.
Work Days Paid is the total short term disability (STD) days and rehabilitation income continuity (code R) days paid in the year regardless of year of injury.
