Costs to refi debt are one timers and are well worth the interest savings and alignment for debt credit rating. I'd be a buyer but like I said the other day, I found a once in a lifetime op in something else, and I'm all over it.
I'm not entirely out of NXP, I hold 10% of my former holding. The 90% was sold at 27.50, cost me 26+. Should NXP trade down to those levels again, I may establish another position.
