Thank you, John and good morning everyone. I'd like to begin my comments on the financial results by highlighting the fact that Robinson achieved record results across the board. Gross revenues, net revenues, and operating income for both the quarter and the full year were at all-time highs. All three of our reportable segments contributed to the success by growing both net revenues and operating income at a double-digit rate in the fourth quarter. Each segment expanded operating margin significantly in the quarter as well. From a cash flow perspective, we knocked it out of the park generating over $700 million in free cash flow and returning nearly $600 million to our shareholders during the year. Our enterprise platform has been carefully and thoughtfully constructed over many years for both scale and leverage through all types of environments and cycles. We are appropriately proud of this performance. Now, on to Slide 4 and our financial results. Fourth quarter total revenues increased 4.5% to $4.1 billion driven by higher pricing across most transportation service lines. Volume growth in LTL, ocean, and customs and higher fuel cost. Total company net revenues increased $82 million or 13% in the quarter to $714 million. Net revenue growth was led by truckload services up $53 million and LTL services up $12 million. We delivered double-digit net revenue growth in ocean, air, and customs for a combined increase of $15 million in the quarter. Fourth quarter monthly net revenue per business day was up 10%, 11%, and 13% respectively in October, November, and December. Total operating expenses increased $37 million an 8.9% increase versus the prior year period. Personnel expenses increased 8.9% primarily as a result of increases in our performance based compensation that aligns the interest of our employees with our shareholders. Total company average headcount increased slightly in the quarter and slowed sequentially from the 2.6% growth in the third quarter. The fourth quarter included headcount reductions in both Global Forwarding and Robinson Fresh. SG&A expenses were up 8.8% in the quarter to $119 million. The primary drivers were increases in outside professional services, occupancy, and travel and entertainment costs. Total operating income was a record $256 million in the fourth quarter, up 21.2% over last year. Operating margin expanded 240 basis points versus last year and 40 basis points sequentially to 35.8%. Our teams did an excellent job of achieving operating margin leverage in the quarter and the year. This has been and will remain a top priority for our organization. Fourth quarter net income was $187 million, an increase of 22.7%. Our diluted earnings per share was $1.34 in the fourth quarter up from $1.08 last year. Slide 5 covers other income statement items. The fourth quarter effective tax rate was 23.9%, up from 21.1% last year. Recall that the year ago period included one-time tax benefits totaling $31.8 million. For the full year our tax rate was 24.5% and we expect our effective tax rate to be between 24% and 25% again in 2019. As noted throughout the year, we adopted the new accounting standards update for revenue recognition in the first quarter of 2018. As a result, in-transit shipments are now included in our financial results. This policy did not have a material impact on our overall operating results for the year. However, it did significantly decrease gross revenues in our Robinson Fresh sourcing business including a $37 million reduction in the fourth quarter of this year. For the full year, sourcing gross revenues were negatively impacted by $121 million. Fourth quarter interest and other expense totaled $9.5 million, down from $17.5 million last year. Every quarter we are required to revalue our U.S. dollar working capital and cash balances against the functional currency in each country where we conduct business and hold U.S. dollars. The resulting gain or loss is reflected on the income statement. The U.S. dollar strengthened against several of our key currencies this quarter resulting in a $2.4 million gain from currency revaluation. Movements in currency valuations will continue to have an impact on our quarterly net income and we will continue to break out this impact in future quarters. The gain in currency valuation was partially offset by higher interest expense due to higher interest rates, while our overall debt balance was down. Our share count in the quarter was down just over 1% as share repurchases were partially offset by the impact of activity in our equity compensation plans. Turning to Slide 6, we had another strong quarter of cash generation. Cash flow from operations totaled $264 million in the quarter, up 59% versus last year. For the full year, cash flow from operations increased nearly 107% to $793 million. A combination of increased earnings and improved working capital performance drove the fourth quarter and full year improvement. Capital expenditures totaled $14.3 million for the quarter and $63.9 million for the year. In 2019 we expect capital expenditures to be between $80 million and $90 million. The increased spending will be primarily dedicated to technology. Our capital distribution is summarized on Slide 7. We've returned $168 million to shareholders in the quarter through a combination of share repurchases and dividends, a 42% increase versus the prior year period. For the full year we returned $590 million to shareholders, a 28% increase. In 2019 we will continue to evaluate and deploy our capital to add value to our network of customers and carriers and generate returns for our employees and shareholders. We will look to acquire quality companies that fit our strategies, business model and culture, and we will continue to reward our shareholders through buybacks and dividends. Now, on to the balance sheet on Slide 8. Working capital increased 12% versus the prior year period, driven by higher gross revenues and the resulting increase in accounts receivables. The contract assets and accrued transportation expense lines on the balance sheet primarily reflect in-transit activity in accordance with the adoption of revenue recognition. Our debt balance at the quarter was $1.35 billion. Across our credit facility, private placement debt, accounts receivable securitization and senior notes, our weighted average interest rate was 4% in the quarter. Slide 9 captures our full-year financial performance. We delivered double-digit growth in net revenues and operating income and a 100 basis point improvement in operating margin. Strong operating profit performance combined with improved working capital and the benefits of corporate tax reform drove a 32.5% increase in our earnings per share. Once again it bears mentioning, 2018 net revenues, operating income, earnings per share, and cash flow from operations all represent record levels of performance for C.H. Robinson. I'd like to congratulate all of our teams across the globe on your outstanding performance in 2018. Our great results this year reflect our focus on profitable growth and our vigorous efforts to grow our business while maintaining strong operational excellence. I'll wrap up my comments this morning with a look at our current trends. Our consistent practice is to share the per business day comparison of net revenues and volume. January 2019 global net revenues per business day have increased approximately 9% and North American truckload volumes have increased approximately 3%. As we look ahead to the balance of the first quarter, we wanted to highlight an item from our 2018 first quarter results. Driven by the tight truckload market last year we saw sequential acceleration in our net revenue growth during the first quarter of 2018. Last year net revenue per business day increased 7%, 12%, and 12% respectively in January, February, and March. Additionally, the 2019 first quarter has one last business day versus the first quarter of 2018. Thank you all for joining us this morning. We appreciate you all listening. I will now turn it over to Bob to provide additional context on our segment performance.
