For your information, a phrase much used in official and business letters, is almost always padding, inserted without thought and without significance.
For your information this machine is required for the abovementioned power station.

For your information I would inform you that it will be necessary for you to approach the local Agricultural Executive Committee.
This last example, taken from a letter I received myself, shows up the futility of this curious cliché. It was not even true that I was being told this "for information"; "for action" would have been more appropriate.
