# Understanding a Balance Sheet: Assets, Liabilities and Equity

> A clear, fully sourced introduction to the balance sheet — what assets, liabilities and shareholders' equity mean, and why they always balance.

A balance sheet is one of the three main financial statements companies publish, alongside the income statement and the cash-flow statement. It is a snapshot, on a single date, of what a company owns and owes. [1]

## The accounting equation

Every balance sheet is built around one identity: Assets = Liabilities + Shareholders' Equity. The SEC's investor guide states this plainly: 'A company's assets have to equal, or balance, the sum of its liabilities and shareholders' equity.' [1]

## Assets

The IFRS Conceptual Framework defines an asset as 'a present economic resource controlled by the entity as a result of past events,' where an economic resource is 'a right that has the potential to produce economic benefits.' [2] Examples include cash, inventory, equipment and buildings.

## Liabilities

The same IFRS framework defines a liability as 'a present obligation of the entity to transfer an economic resource as a result of past events.' [2] Examples include bank loans, accounts payable and unpaid taxes.

## Equity

Equity is what is left for the owners after liabilities are subtracted from assets. The IFRS framework defines equity as 'the residual interest in the assets of the entity after deducting all its liabilities.' [2]

## Why it always balances

Because equity is defined as the residual (Assets − Liabilities), the two sides of the balance sheet are mathematically equal by construction. [1][2]
