What type of information would be relevant for assessing supplier costs?

The relevant information for assessing supplier costs is found in company annual reports. Annual reports provide comprehensive financial data about a company's performance over the past year, including revenue, expenses, profit margins, and overall financial health. This information is crucial for understanding how suppliers might price their products and services, as well as assessing their ability to meet financial obligations and invest in quality improvements.

Annual reports also often contain insights into the company’s operational efficiency, cost structure, and market position, allowing for a deeper analysis of how supplier costs are influenced by various internal and external factors. By closely reviewing these reports, organizations can effectively evaluate potential suppliers for cost competitiveness and financial stability, which is essential for making informed sourcing decisions.

The other options do not directly relate to supplier cost assessments. Consumer feedback surveys focus more on customer satisfaction and product quality rather than supplier financials. Sales forecasts provide predictions about future sales but typically do not convey information about suppliers’ pricing structures or financial situations. Marketing strategies mainly outline how a company plans to promote and sell its products, without giving insight into supplier costs.
