The most significant items where estimates are used are contingent liabilities, the liability for employee severance benefits and the useful life of tangible capital assets. Actual results could significantly differ from those estimated. Management’s estimates are reviewed periodically and, as adjustments become necessary, they are recorded in the financial statements in the year they become known.

4. Parliamentary Authorities

The Agency receives most of its funding through annual Parliamentary authorities. Items recognized in the Statement of Operations and Agency Net Financial Position and the Statement of Financial Position in one year may be funded through Parliamentary authorities in prior, current or future years. Accordingly, the Agency has different net results of operations for the year on a government funding basis than on an accrual accounting basis. The differences are reconciled in the following tables:
