I did a google search on the definition of mid single digit. Interestingly the only company that I could find that defined what they meant when referring to this type of term was Gap Inc. For mid single digit it was 3.5 - 6.4%
Based on the disappointing royalties that HALO has earned to date I would reckon that the 3.5% is highly likely. I admit my 2% was too low - or at least hope it was!
