It can be worse. I got a letter recently from a mutual fund saying I'd done nothing with my account for years, and if they didn't hear from me soon, they were going to hand it over to the government. (I'm a buy and hold, hold, hold, hold, investor.)

1. Verify balances and look for any sign of fraud.
2. Verify contact information (address / phone / email).
3. Titling: As you get older, make sure you understand how your account is titled. Individual / POD / Joint / Joint WROS / Trust / etc. Each of these has specific consequences to you.
4. Beneficiaries: Similarly, make sure you understand the significance of submitting beneficiaries on your accounts.
Example: I missed updating an older account to include my new wife.
