Why does net asset value of a business not change when assets are purchased on credit?

The net asset value of a business remains unchanged when assets are purchased on credit because the increase in assets is offset by an equal increase in liabilities. When a business acquires an asset, it adds to its total assets, but it simultaneously incurs a liability equal to the purchase price, reflecting the obligation to pay for the asset in the future. Thus, the overall net assets, calculated as total assets minus total liabilities, remain the same.
