Adding X, Y data to Attribute Table

Question

I am and have successfully added X,Y data using the built in ArcGIS toolbox 'data management tools' > 'Features' to add X, Y data to the attribute table from point data. However this has caused a problem, for I have been using the data to build up a model in Petrel, hence exporting the X,Y coordinates via a text file and my collegue dosen't understand why the coordinates have negative values. I suggested this is due to them being south of the 'equator' and west of the central meridian on the projection system I have been using.

Is there a way of exporting the X, Y values in Decimal Degrees rather than meters (which I think it exports the data as)? I have a screen shot below showing the negative attributes in the Y coloumn. The values are quite large intergers suggesting meters as the output type.

Oh, I see. I bet the negative DD values were in the latitude/Y field. Thanks!

Yep they were. This all worked out successfully, now to make the maps look beautiful...

Sorry about the attachment I must have made it too small.

The original XY plots were in meters and I used the calculate geometry tool to change this to DD. This worked just fine, but with some negative values. These values were commonly negative to -2 or -3 DD, these points fall outside of the UTM grid I was told to put the points into (37N) so are an eventuality I figure.

Thank you very much for your help.
