AUROC curve is more than 1

hi all,
Is it possible that AUROC is more than 1?

There's a very nice explanation of interpretations of the area under an ROC curve here:

The Area Under an ROC curve describes:

Accuracy is measured by the area under the ROC curve. An area of 1 represents a perfect test; an area of .5 represents a worthless test.

So, no, greater than 1 is not possible, as that would be more than 100%.
