I maintain a saved report of my retirement accounts to show a combined value of all accounts I have earmarked for retirement. One of the accounts, a rollover IRA, is showing a value in this report significantly higher than is shown in the account register—and the register matches the value of this account at Vanguard.
In other reports I can run, it shows the correct value. What could possibly be happening in this one report, that shows the value of a single account being 10-15% higher than it should be. This report contains several accounts, and all the other show correct valuations.
