Actuarial Estimates

Actuarial estimates are calculations done by actuaries to predict future liabilities, expenses, and life expectancies, often for use in insurance and pension plans.

Other Comprehensive Income

Components of comprehensive income that are excluded from net income, including items such as unrealized gains or losses on foreign investments, pension plan adjustments.

IFRS

A collection of global accounting standards, International Financial Reporting Standards dictate the reporting methods for specific transactions and events in financial statements.
