Thank you, Sharon. First, I want to let our investor base and our employees know that for the fourth consecutive quarter, we have exceeded our internal EBITDA forecast. Our fourth quarter adjusted EBITDA was $39.7 million, which exceeded our forecast by almost $11 million. For the year, our adjusted EBITDA was $114.5 million compared to our disclosed adjusted EBITDA range of $95 million to $102 million for the year of 2021. This strong performance benefits us financially primarily in two ways. First, it helps us pay down our absolute debt at a much faster pace. And it also accelerates the reduction of our leverage ratio closer to our stated goal of below 4 times. Second, I believe this strong cash flow performance, along with significantly improved financial metrics should position us well with the bond rating agencies. This is a significant step to improving our ability to achieve a beneficial refinancing of our existing bonds by the end of the third quarter at a much cheaper cost of capital compared to what we are now paying. I'm very pleased that we are better positioned to achieve that goal. Now we need to continue to execute strong cash flow performance in 2022 in order to ultimately achieve our third quarter goal of refinancing this debt at a much lower cost. I'm very confident we can execute this plan. Now I'd like to discuss both our fourth quarter and our full year performance by business segment. Overall, as I previously mentioned, we had adjusted EBITDA of $39.7 million in the fourth quarter. This compared to adjusted EBITDA of $17.4 million in the fourth quarter of 2020. For the full year, we had adjusted EBITDA of $114.5 million compared to $94.9 million in 2020. For the fourth quarter, our largest cash flow contributor was our natural gas liquids segment, which had adjusted EBITDA of $12.8 million compared to just $2 million in the fourth quarter of 2020. The significant majority of our natural gas liquids cash flow was from the performance of our butane business, which had adjusted EBITDA of $11.1 million in the fourth quarter compared to a negative cash flow of $0.6 million a year ago. In the fourth quarter, we experienced expanded butane margins as strong refinery demand began in October. Just like every year, this was due to the seasonal change in gasoline vapor pressure rules which allow refineries to blend butane into their gasoline pool. Unlike a year ago, margins in this business were more typical of our historical fourth quarter butane margins. In the fourth quarter of 2020, we experienced reduced demand in our butane optimization business due to the impact of COVID-19 on refinery utilization and backwardation of the forward price curve delaying refinery purchases, causing misalignment of our physical sales and financially hedged volumes. This explains why there was a negative cash flow in last year's fourth quarter compared to more normal cash flow experienced in the fourth quarter this year. For the full year, our NGL segment had adjusted EBITDA of $28.4 million compared to $12 million in 2020. This improvement year-over-year was driven by our butane business, which experienced a normal fourth quarter in 2021 compared to the weak fourth quarter of 2020. Looking towards the first quarter of 2022, even though margins should be strong, first quarter cash flow will not be as much as the fourth quarter in our butane business as the volumes sold will be less. This is due to the smaller amount of inventory we have remaining in storage at December 31. In other words, we just have less to sell. Now I'd like to discuss our Sulfur Services segment, which was our second largest cash flow contributor in the fourth quarter. This segment had adjusted EBITDA of $11.4 million in the fourth quarter compared to $7.4 million a year ago. Our fertilizer business had adjusted EBITDA of $7.8 million in the fourth quarter compared to $5 million a year ago. Although our volume of fertilizers sold was very similar for both quarters, we experienced overall margin expansion in the fourth quarter, primarily driven by the fundamentals of supply and demand. This margin expansion was the primary reason for our improved cash flow in the fourth quarter compared to the fourth quarter of 2020. Our pure sulfur side of this segment had adjusted EBITDA of $3.6 million in the fourth quarter compared to $2.4 million a year ago. This improvement was primarily volume driven as refinery utilization was 88% in the fourth quarter compared to 77% a year ago, allowing us to handle more sulfur produced from refineries compared to 2020. For the year, our entire Sulfur Services segment had adjusted EBITDA of $34.3 million compared to $32.5 million a year ago. Our fertilizer business had adjusted EBITDA of $24 million in 2021 compared to $17.3 million in 2020. Just like the fourth quarter, for the full year of 2021, we experienced improved supply and demand fundamentals, which has contributed to continuing rising fertilizer prices, helping us to expand our margins compared to 2020. These improved margins were the primary driver for our improved cash flow performance in our fertilizer business. For the year, our pure sulfur side of the business had adjusted EBITDA of $10.3 million compared to $15.1 million a year ago. Negatively impacting our sulfur volumes was the impact of Winter Storm Erie in the first quarter of 2021 and Hurricane Ira in the third quarter of 2021. These extreme weather events had a significant operational impact to the Beaumont and Lake Charles area refineries, which produced the majority of the sulfur we handle. Additionally, in 2020 we had business interruption proceeds of $2.7 million, which did not occur in 2021. Looking toward the first quarter of 2022, we continue to see strength in our fertilizer business due to strong pricing and consistent demand. We also see stability in our pure sulfur business as refinery utilization and sulfur production have become more consistent. Our third strongest cash flow generator in the fourth quarter was our Terminalling and Storage business, which had adjusted EBITDA of $11 million compared to $10.6 million a year ago. Our packaged lubricant and grease business improved $0.9 million compared to last year's fourth quarter. This was primarily due to strengthening margins driven by improving supply and demand fundamentals. This has been a continuing trend throughout the year. Offsetting this was the cash flow at our Smackover refinery, which was down $1.1 million in the fourth quarter compared to a year ago. This was due to the scheduled contract reduction to the throughput rate related to capital recovery fees, which became effective January 1 of 2021. Additionally, the refinery experienced increased natural gas costs compared to a year ago. However, the refinery is protected against any natural gas cost above $4 per Mcf as commercial throughput contract that runs through 2031. For the year in this segment, our adjusted EBITDA was $43.5 million compared to $46.9 million a year ago. While our packaged lubricant and grease business had a cash flow increase of $1.8 million due to improving fundamentals, our Smackover refinery had a cash flow decrease of $3.6 million. This decrease was due to the scheduled contract reduction to the throughput rate in January 2021 and the increase in natural gas costs compared to a year ago. Looking toward the first quarter, we believe the cash flow from this business segment will be stable. Our final business segment to discuss is our Transportation segment, which had adjusted EBITDA of $8.8 million in the fourth quarter compared to $1.7 million a year ago. Our land transportation business saw a significant improvement as fourth quarter cash flow was $7.6 million compared to $3 million a year ago. While we experienced a modest low count increase of 3%, we were able to increase our revenue by 23% compared to a year ago. This revenue increase more than covered our increasing operating costs in our business. Our customer base has been very understanding of the inflationary pressure we are experiencing in our driver pay, insurance costs and other operating expenses and has supported our requested rate increases. Fundamentally, truck transportation was in very tight supply in 2021. And we continue to see tightness in the market continuing into 2022. Our Marine Transportation business also saw improvement compared to the fourth quarter of last year. Adjusted EBITDA was $1.2 million compared to a negative $1.3 million a year ago, an improvement of $2.5 million. This was the fourth consecutive quarter of increasing Marine Transportation cash flow as we continue to see steadily improving fundamentals in this business. Our daily barge rates are very similar to a year ago, but we experienced a significant 37% improvement in our third-party barge utilization. For the year, our Transportation segment had adjusted EBITDA of $24.1 million compared to $20 million in 2020. We saw significant improvement in our land transportation business as it had cash flow of $23.9 million in 2021 compared to $15.2 million a year ago. The cash flow in our land transportation business grew every quarter in 2021 when compared to the previous quarter. We believe there will be continuing cash flow growth in 2022 as fundamentals remain strong. For the year in our Marine Transportation business, we saw a decrease in cash flow from $4.8 million in 2020 to $0.2 million in 2021. Marine Transportation cash flow performance was strong in the first half of 2020 as we then operated under contract with rates that began to roll over to cheaper spot rate contract the second half of 2020. This weakness carried over into 2021, but we began to see slow improvement in cash flow throughout 2021, finally, turning positive in the third quarter. We believe this improving trends will continue throughout 2022, and our cash flow in this business will be better than 2021. This summarizes our performance by business segment for both the fourth quarter and the year. Now I would like to turn the call back over to Sharon to discuss our balance sheet, capital resources and our 2022 guidance.
