Ashish,
For my job, I oftentime in the past used
CapitalIQ,
Moody's, and of course my favorite of all, Bloomberg's terminals.
Both CapIQ and Moody's require purchasing a license though, as far as I know at least. If it's for your job that you need the data, perhaps you can check if your company has/can get access to a license?
I hope some other EFer is able to point you to free resources of this type, if they are available - you didn't specify whether you were hoping to access the info for free or whether paying for a license wasn't an issue.
Good luck!
