It would allow federally regulated private sector and Crown Corporation employers to offer a
TBP to their employees, or to convert an existing DB pension
plan into a
TBP.
So if a funding deficit arises in a
TBP (because of underfunding, or lower - than - expected investment returns, say), part or all of it can be compensated for by reducing accrued benefits to employees whereas a traditional DB
plan would require the entire deficit to be funded by increased contributions on the part of the employer — the federal government (and by extension, the taxpayer).
