It's tricky finding information on private companies, but public ones have to open their books, and their reports are in my experience always posted to their websites. Look for "investor relations."

Fidelity is private. I can find you some financials on them via a subscription database, if you're still interested.
State Street Annual Reports
U.S. Bancorp Financial Info/SEC filings
Deutsche Bank reports
JP Morgan Annual Report and Proxy
GE financial reporting
Bank of America Investor Relations

I'm sorry that I don't actually know what to do with the financials now that I've found them. I suspect 10+ weeks later the need has expired anyway. Sorry about that.
