Thanks, Dane. It is a pleasure to be with you today. Total revenue was $258,000 for the fourth quarter of 2021 compared to $191,000 in the fourth quarter of last year. And fourth quarter product sales this year increased by 149% sequentially from the third quarter of 2021, an increase of 146%. Revenue in both periods was driven by sales to neurotherapy clinics in Canada that had been authorized to provide our PoNS therapy and remained impacted by the significant business disruption in Canada related to the COVID-19 pandemic as well as reduced introductory pricing. However, beginning late in the third quarter of 2021, some of the COVID restrictions in Canada were loosened, creating an uptick in activity. For the fourth quarter of 2021, our gross profit increased to $129,000 versus a gross loss of $10,000 in the prior year, which was impacted by an increase in the inventory reserve. Operating expenses for the fourth quarter of 2021 increased to $4.2 million compared to $3 million in the fourth quarter of 2020, an increase of $1.2 million. The planned increase primarily resulted from increased clinical and development activities preparing for the U.S. commercial launch of PoNS. Operating loss for the fourth quarter of 2021 was $4.1 million as compared to $3 million for the prior year period. We reported net loss for the fourth quarter of 2021 of $4.1 million or a loss of $1.31 per share compared to a net loss of $2.9 million or $1.70 per share - $1.77 per share for the same period last year. Turning to a discussion of our balance sheet condition and recent financing activities. Our cash burn from operations for 2021 was $13.4 million compared to $11.7 million during 2020, adding $3.5 million during the fourth quarter, which was only slightly above the average quarterly burn rate through the first three quarters as we manage spending while preparing for our U.S. commercial launch. As of December 31, 2021, we had $11 million of cash and no debt. In addition, we have $14.4 million available under our equity line of credit with Lincoln Park Capital, subject to the terms and conditions therein, ensuring a source of equity capital, if and as needed, which could significantly extend our runway. Turning to our outlook. We currently expect first quarter 2022 revenue to range from $150,000 to $170,000, approximately double the first quarter revenue in 2021. We expect subsequent quarterly revenue to increase sequentially each quarter throughout the year as the U.S. commercialization of PoNS takes hold. To date, we have been successful in securing our first PoNS prescriptions, and we currently expect the first U.S. shipment to occur in April. With that, operator, let's now open the call for questions.
