Why are you concerned with divvy sustainability???Think how much better you would be if Corus invested at least a half of the divvy cash in a new revenue sources!!!
Had the management been able to define, develop and execute successful business plan to grow revenue from digital technology (and perhaps new business lines), you would benefit in capital gain much more than from collecting $1.14 per year.
Unfortunatelly the current management is totally inept at growing and developing this company, so collect divvy as long as they last..., and they may not last that long given present and foreseen decline in revenue from tv ads.
