Thank you, Tony, and good afternoon, everyone. The net loss from continuing operations of $112 million in the fourth quarter represented a loss of $16.46 per share. The fourth quarter included $162 million of pretax gains from debt exchanges and repurchases, partially offset by charges of $71 million mainly from asset impairments for a net after tax gain of $52 million. Fourth quarter results compared to a loss of $161 million or $23.42 per share in the third quarter. The third quarter included net after tax gains of $6 million related to gains from debt repurchases, asset impairments and severance costs. Revenue from operations for the fourth quarter was $443 million, a sequential gain of 1%. Revenue improved in most segments with only International and Rig Tech partially offsetting those increases. In the Lower 48, despite some deterioration in the average pricing for our fleet, drilling revenue of $103 million increased by $6.9 million or 7% as our rig count improved by 11%. Lower 48 rig count at 53.6 was up sequentially by 5.4 rigs, which is 2.4 rigs more than we had anticipated. Daily rig revenue in the Lower 48 at $20,950 decreased by about $800 as we continue to sign contracts at current market rates that are lower than the average for our fleet. In aggregate, revenue in our other US markets decreased by $3 million, reflecting a reduction in our offshore activity as one of our rigs finalized its contract in the prior quarter. Fourth quarter revenue fell with a lower rig count as well as with the absence of the demobilization revenue we invoiced in the third quarter. International drilling revenue at $245 million decreased by $3.3 million or 1%. This decrease was primarily related to declines in activity across several markets, as rig count fell by almost nine rigs or 12%. This rig count reduction was higher than anticipated. Saudi rig count decreased by five rigs, two more than expected due to temporary suspensions as Saudi Aramco adjusted its drilling activity towards the end of the year. Kazakhstan and Colombia each had a one rig termination, both of which we did not anticipate. In addition, Algeria and Kuwait had contracts expiring late in the third quarter that were not renewed. The softer rig count was offset by approximately $4 million in revenue from early terminations and from the restoration of full day rates for customers with negotiated COVID rates. Canada drilling revenue was $14.8 million, an increase of $4.1 million or 38%. Rig count increased by 2.3 rigs on the usual seasonal ramp up in activity. The quarter also benefited from $700 increase in revenue per day. Nabors' Drilling Solutions revenue of $32 million, up $2.7 million or 9% primarily reflected strong increases in our high margin performance drilling offerings as well as our RigCLOUD installations. During the quarter, we continued to increase the penetration of these services with Nabors and third party rigs, while also benefiting from the higher lower 48 rig count. Rig Technologies revenue decreased by $1.1 million or 4% as several clients delayed deliveries beyond the end of the year. Total adjusted EBITDA for the quarter was $108 million compared to $114 million in the third quarter. The decrease was driven by $7.4 million reduction in our International segment and a more modest reduction in Rig Technologies. These were partially compensated by improvement in NDS as well as U.S. and Canada Drilling. U.S. Drilling adjusted EBITDA of $62.2 million was up by $1.6 million or 3.1% sequentially. The Lower 48 performance came in better than expected on the stronger rig count and on higher margins. Daily rig margin of $9,541 was about $500 above the high end of our previous guidance and in line with the third quarter level. Decreased costs, mainly a reduction of property tax expenses, offset the pricing deterioration we experienced in the fourth quarter. Cost control efforts continue to be a strong focus as we bring rigs back to work. As an example, we have improved our rig stacking and reactivation procedures, and the related costs are significantly better than in the last cycle. For the first quarter, we expect daily rig margins of approximately $8,500, driven mainly by the repricing of renewals as rigs continue to roll off pre pandemic contracts and by the return to more normal levels of property taxes, with an adverse impact of approximately $600 per day. We forecast a two to three rig increase for the first quarter of 2021. Our current rig count in the Lower 48 is 57 rigs. International adjusted EBITDA decreased by $7.4 million to $64.5 million in the fourth quarter or 10% sequentially. The lower rig count was somewhat offset by early termination revenue and return to full day rates from several customers. Average international rig count was 62.6, a reduction of 8.7 rigs or 12%. Daily gross margin for the quarter was $13,500 as compared to $12,700 for the prior quarter. The fourth quarter included approximately $800 per day in early termination revenue. Turning to the first quarter. We expect an international rig count increase of two to three rigs as several Saudi rigs returned to work progressively during the quarter, and for gross margin per day to settle between $12,500 and $13,000 per day. Our current rig count in the International segment is 67 rigs. Canada adjusted EBITDA of $3.5 million increased by $1.4 million. Rig count at 9.7 rigs was 2.3 higher sequentially. Gross margins per day of $4,633 also increased due to the higher activity level. We expect both rig count and daily margins to improve again in the first quarter by three rigs and $500 respectively. We currently have 14 rigs operating in Canada. Drilling Solutions posted adjusted EBITDA of $10.3 million, up from $7.1 million in the third quarter or 44%. The improvement reflected mainly the higher revenues from performance drilling offerings and RigCLOUD infrastructure. In addition, a shift in our US casing running services from manual to integrated materially improved the profitability of that business line. We expect adjusted EBITDA in the first quarter to be in line with the strong fourth quarter. Rig Technologies reported adjusted EBITDA of $0.5 million in the fourth quarter, a decrease of $800,000. The first quarter EBITDA should be similar to the fourth quarter. Now let me review our liquidity and cash generation. Looking back at 2020, it was a challenging year. Nevertheless, we maintain our focus on improving liquidity and leverage, and we made significant headway. The capital and cost discipline actions we announced earlier, including cost cuts to corporate and operations overhead, salaries, dividends and capital expenses, were fully executed. These actions were instrumental in helping Nabors deliver $184 million in free cash flow for the full year. In 2020, we reduced overhead spend by 24%. These reductions began in the second quarter and translated into cash savings of approximately $90 million over the last nine months of the year. Our run rate in the fourth quarter represents a nearly 28% reduction over the 2019 quarterly average. The decrease in overhead, combined with CapEx reductions of $170 million and dividend cuts of $7 million, translate into total cash savings of approximately $267 million versus our initial plan for 2020. Despite the substantial drop in activity and consequent EBITDA shortfall, Nabors delivered free cash flow almost in line with our initial pre COVID target. In the fourth quarter, net debt declined by $290 million to $2.49 billion. This reduction was driven by positive free cash flow and by several debt exchanges we completed during the quarter. Free cash flow, defined as net cash from operating activities less net cash used for investing activities, totaled $66 million. This compares to free cash flow of approximately $9 million in the prior quarter. The fourth quarter included minimal interest payments as compared to semiannual interest payments of approximately $80 million in the third quarter. During the fourth quarter, we experienced a slowdown in collections from a significant number of our customers. While our quarterly free cash flow was affected by some $30 million, we expect this situation to prove temporary. For the first quarter, we anticipate breakeven cash flow. Please keep in mind that semiannual interest payments for all our senior notes are paid in the first and third quarters. In addition, the first quarter has an unusually high number of onetime annual payments, such as property taxes and bonus payments to our workforce. These payments and other onetime annual outflows in the first quarter typically amount to about $30 million. Offsetting these negative impacts on our cash flow, we anticipate a strong recovery in our quarterly collections. We have already experienced an increase in collections during the month of January. During the fourth quarter, we completed a public debt exchange and various private exchanges. These transactions reduced our total debt obligations by $284 million and reduced our near term maturities. During 2020, we reduced through repayments, buybacks or exchanges, near term notes with maturities in or before 2023 by an aggregate amount of $1.5 billion. Subsequent to year end, we further addressed our capital structure by completing additional debt exchanges and open market purchases of our notes. These transactions reduced our debt obligations by an additional $22 million. Let me continue with a comment on capital expenses. Capital spending in the fourth quarter was $41 million compared to $39 million in the prior quarter. For all of 2020, CapEx totaled $190 million, $10 million less than we had planned. We are targeting CapEx of $50 million for the first quarter and of $200 million for the full year 2021, excluding Saudi newbuilds for SANAD. At this point, SANAD has been awarded three drilling contracts by Saudi Aramco, and we have issued one purchase order for the first rig. We do not expect that any newbuilds we delivered in 2021. Nonetheless, CapEx for SANAD newbuilds, if any, would be paid out of SANAD funds. The final comment, it is worth mentioning that we determined together with our SANAD management team and with our JV partner, Saudi Aramco, that at year end 2020, SANAD held cash balances beyond its future needs. Consequently, a cash payment of roughly $50 million to each partner was approved. This payment was executed in the month of January. With that, I will turn the call back to Tony for his concluding remarks.
