We believe a normal gross profit percentage range for our business is 51% to 53%. This is based on our current mix of products, geographies, end markets, and end market uses (such as industrial production business versus maintenance business). Our business operated below our expected gross profit range at the end of 2009, and expanded into the low end of this range during 2010. In the second quarter of 2010, we moved into the middle of the range as the three components of gross profit improved, the contribution being split fairly evenly between the three components. We remained in the middle of the range until the fourth quarter of 2011. In the fourth quarter of 2011, our gross margin felt pressure and dropped to the lower end of the range. This drop was primarily due to changes in our transactional margin (primarily due to changes in product and customer mix), lower vendor incentive gross profit, and lower freight utilization. The latter two items created half of the gross margin drop and are more of a seasonal issue. In the first quarter of 2012, our gross margin improved nominally over the previous quarter. This was primarily caused by the seasonal improvement of vendor volume allowances as rising fuel prices offset our improvements in freight utilization. In the second, third, and fourth quarters of 2012, our gross margin improved when compared to the first quarter. Most of this improvement related to improvements in our transactional gross margin. The improvement was partially offset by the weakening of our selling prices in certain foreign markets due to changes in the exchange rate. One item of note, in the fourth quarter of 2012, we experienced a drop off in the freight component of our gross margin due to lower freight utilization, a typical pattern due to the seasonal drop off in business; this gross margin decline was offset by an improvement in the remaining portion of our transactional gross margin that centers on product gross margin.
