The need for basic earnings per share (EPS) information arises from the fact that shareholders and investors want to evaluate a company's financial performance and profitability on a per-share basis. Basic EPS provides a measure of the amount of profit or loss that is attributable to each outstanding ordinary share of a company's stock.

Here are some reasons why basic EPS information is important:

1. Comparison: Basic EPS provides a standardized metric that can be used to compare the financial performance and profitability of different companies in the same industry or sector. Investors can use this information to evaluate how well a company is performing relative to its peers.
2. Investment decision-making: Basic EPS information can help investors make informed investment decisions by providing insight into a company's financial performance and prospects. Higher EPS may indicate that a company is performing well, which may be attractive to investors looking for profitable investment opportunities.
3. Accountability: Basic EPS information can help hold a company's management accountable for their performance. By providing information on the amount of profit or loss that is attributable to each share of the company's stock, basic EPS information can help shareholders and other stakeholders evaluate the effectiveness of the company's management.
4. Transparency: Basic EPS information can help promote transparency in financial reporting by providing a standardized metric that is calculated and presented in a consistent manner across companies and industries. This can help ensure that investors have access to accurate and reliable information to make informed investment decisions.

Overall, basic EPS information is an important metric that investors use to evaluate a company's financial performance, profitability, and potential for future growth.
