No, it really happened Simfan. I'm just not sure if it will be sustained or if this is a one time thing.
As the full article points out, and wormyguy alluded to in an attempt to appear clever, April is more often than not a surplus month for reasons that should be obvious. A slip back into deficit is not just likely but expected.
A surplus was recorded in 44 of the last 58 Aprils. Whereas 2009, 2010 and 2011 were among those 14 'bad' Aprils, 2012 was not one of them. Therefore, an economic recovery is indisputably underway.
