How this growth is measured
Year-over-year growth here compares each year's median payment with the year before, not the calendar-year total. Ex-dividend dates drift, so a quarterly payer can book five ex-dates in one calendar year and four in the next. Comparing raw yearly totals would show a phantom cut of around 25% in a year where the company did nothing but pay slightly earlier. Using the median payment removes that distortion, and also ignores one-off special dividends.
Years marked “timing” booked a different number of payments than IRM's usual cadence, so their total is not directly comparable with neighbouring years.
