TORONTO - The OMERS pension fund is reporting a 6.7 per cent net return last year on the investments it manages for municipal and other public-sector workers across Ontario.

OMERS says its assets grew by $5 billion last year after expenses to about $77 billion, with 52 per cent in public investments and 48 per cent in private investments.

Returns for its private investments -- including shares of private companies, infrastructure and real estate -- outperformed public investments last year.

OMERS says its public investments earned 0.7 per cent while the private investments gained 14.5 per cent in 2015.

It also received $3.8 billion in contributions from plan members and employers, and paid out $3.4 billion in benefits.

The fund administrator says the results exceeded its long-term funding requirement for a 6.5 per cent annual return. Its funded status improved to 91.5 per cent from 90.8 per cent in 2014.
