Marty Freeman
Executive Vice President and Chief Operating Officer at Old Dominion Freight Line
Thank you, Greg, and good morning. I want to first of all start by thanking Greg for his leadership and significant contributions to OD over his career, while also recognizing each OD employee for their critical role in our success. Together, we have produced remarkable improvements in our financial and operating results over the long term. And I can assure you that OD's team remains focused on continuing our record of strong profitable growth.
With respect to our first quarter, we delivered solid financial results, especially when considering the ongoing softness in the domestic economy and decrease in volumes. Although these factors contributed to the first decrease in quarterly revenue and earnings per diluted share since the second quarter of 2020, our market share has remained relatively consistent. As a result, we believe our decrease in volumes was largely due to some shippers simply having fewer shipments than normal due to the economy. Although there have been others that are beginning to emphasize price versus service and choosing lower-priced carriers. The operating environment has become more challenging than we anticipated and the expected acceleration in volumes has obviously not occurred. Despite these factors, we have maintained a commitment to our long-term strategic plan. We will continue to focus on providing shippers with superior service to support our ability to maintain our price discipline. Our consistent cost-based approach to manage yield and account profitability has been critical to our ability to improve our financial position over time, which has helped us support and continue to invest in technology and service center capacity. While capacity is not currently an industry issue due to the weakness in industry volumes, we believe this will once again become a critical differentiator for us when the economy improves. We believe our long-term consistent investment in service center capacity has been and remains a strategic advantage that supports our long-term market share goals.
During this period of revenue decline, we will also maintain a disciplined approach to managing our variable cost and discretionary spending to protect our profitability. This starts with a commitment to maximizing the operating efficiency of our fleet and network. Some of our productivity measurements in the first quarter were negatively impacted by the general loss of operating density associated with the decrease in our shipments and weight per shipment. This was evidenced by a 4.9% decrease in our line haul latent load average and a 1.0% decrease in our P&D shipments per hour. We improved our platform productivity; however, and generated a 5.8% increase in our platform shipments per hour. We also reduced our reliance on purchase transportation as compared to the first quarter of 2022 which allowed us to improve the overall efficiency of our operations. This contributed to the improvement in our variable cost as a percent of revenue during the first quarter.
We will also continue to work on improving the efficiency of our operations as we make our way through the balance of this year, which provides an opportunity to generate additional cost savings. While productivity is always a focus, we cannot and we will not allow it to impact our best-in-class service performance. Our team continued to deliver superior service during the first quarter with an on-time service of 99% and a cargo claims ratio of 0.1%. This service performance remains critical to support our yield management strategies.
We have said many times before that to produce long-term improvement in our operating ratio will continue to require a balance between operating density and yield management, both of which generally require a favorable macroeconomic environment. As just mentioned, we lost operating density in the quarter in the current environment due to the decline in volumes and the expansion of our network. Our yield has continued to consistently improve; however, and revenue per hundredweight, excluding fuel surcharges increased 8.6% during the first quarter. We will continue to demonstrate value to our customers by balancing our superior service offering with a consistent cost-based approach to our pricing. The resulting value proposition is unmatched in the LTL industry and will continue to support our ability to increase market share over the long term.
As we look forward to remaining quarters of this year, we currently anticipate the softer demand environment will continue. The second quarter is generally the period when volumes begin to accelerate, but we have yet to see an inflection towards growth. Nevertheless, I want to emphasize that we are well positioned to respond to any acceleration in volumes that might occur if and when the economy improves. Until that time comes, we will continue to focus on managing our costs and delivering value to our customers through our value proposition of on-time claims-free service at a fair price.
Delivering value is a central element of our long-term strategic plan, and we remain committed to execute on this plan regardless of the economic cycle. As a critical part of this plan, we will also continue to execute our capital expenditure program and most importantly, invest in the training, education and development of our OD family of employees. The economy will eventually recover, and we will -- and we are confident that when it does, our team's execution will allow us to achieve further growth and profitability while also increasing our shareholder value. Thanks for joining us today. Adam will now discuss our first quarter financial results in greater detail.
