Severe weather conditions during February negatively impacted our primary operating lanes and limited our ability to achieve internal targets set for the quarter . We recovered well and regained momentum as we progressed through March but not enough to fully recover the February lost opportunities . We will continue to focus on the challenging driver market and are doing whatever is necessary to find , retain , and grow our driving force , which is our most valuable asset . We have been encouraged by our rate improvement results so far this bid season and anticipate additional improvement as we progress through the year . We are also encouraged by the cost control and operating efficiency goals that we believe remain achievable throughout the remainder of the year . " About P.A.M. Transportation Services , Inc. P.A.M.
