amortized cost financial

"Debt issued measured at amortized cost"

Amortized cost is an accounting method that shows the value of a loan or bond on a company’s books by starting with what was paid and then gradually adjusting that amount as principal is repaid and any extra fees or discounts are spread out over time. Think of it like tracking the remaining balance on a mortgage after each scheduled payment. For investors, it matters because it determines the reported value and earned interest of debt holdings, affecting income, balance sheet strength, and comparisons between companies.

designated at fair value financial

"Debt issued designated at fair value"

non-controlling interests financial

"Equity attributable to non-controlling interests"

An ownership stake in a subsidiary held by outside shareholders rather than the parent company, representing the portion of that subsidiary’s assets and profits the parent does not control. For investors, it shows what part of consolidated earnings and equity belongs to others — like a roommate who owns part of a house — which affects how much value and profit per share are truly attributable to the parent company’s shareholders.

IFRS Accounting Standards technical

"prepared in accordance with IFRS Accounting Standards"

International Financial Reporting Standards (IFRS) are a set of common rules for preparing company financial reports so numbers like profit, assets and debt are presented consistently across countries. Think of them as a standardized recipe or blueprint that helps investors compare businesses the same way they would compare cars using the same list of features; consistent reporting reduces surprises and makes it easier to assess value, risk and performance.
