What type of information does Schedule D contain regarding a company?

Schedule D provides a summary of investments held by an insurance company, specifically detailing the allocation of its investments by country. This schedule is important as it gives insight into the geographical spread of an insurer's investments, which can help assess the risks associated with economic fluctuations in different regions. This information is crucial for understanding how well an insurance company is diversified and whether it has exposure to any particular country’s economic conditions. Additionally, it reflects the overall financial strategy and investment policy of the insurance company.

In the context of other options, insurance underwriting practices focus on how risks are evaluated and premiums are determined, which is not what Schedule D covers. Claims and loss ratios relate to the performance of claims made by policyholders and the company's loss history, while rate-making procedures involve establishing the rates that policyholders are charged for coverage. None of these topics fall within the scope of Schedule D, which is specifically focused on investments.
