I Am Working On My Final Paper But I Am Unsure How To Answer These 3 Questions

I am working on my final paper, but I am unsure how to answer these 3 questions:

First, if assets are insured for a financial institution like First National Bank of Michigan or Scottrade Financial Services, who are they insured by and where would I find that information?

Second, Primary Source of funds. What does that mean and where would I find that information for a company such as First National Bank of Michigan or Scottrade Financial Services (there are many more in my project, I am using those as a starting point).

Third, aren’t all individuals a companies primary customer? How would you define a primary customer for companies such as First National Bank of Michigan or Scottrade Financial Services?

I’d appreciate any help in answering these questions, or guidance as to where I could locate such information. I am trying the companies websites, but finding that to be more challenging as it doesn’t answer some of these specific questions.

Thank you!
