Thank you, Craig and good afternoon, everyone. Before I begin my prepared remarks, I'd like to call your attention to our fourth quarter and year end earnings press release that was issued earlier this morning. If you need a copy, it can be accessed on our Web site at ashes.com at press releases under the investors tab. Now turning to our fourth quarter results. For the three months ended December 31, 2020, total revenue was $4,608,000, a decrease of 3.7% compared with $4,786,000 reported for the fourth quarter of 2019. Fourth quarter revenue for the company's proton therapy system installed at Orlando Health in Florida was $1,403,000, a decrease of 5.6% when compared to the fourth quarter of 2019. Total proton therapy fractions decreased 25% compared to the fourth quarter of 2019. Revenue for the company's Gamma Knife operations was $3,205,000, 0.8% decrease compared with the fourth quarter of 2019. Gamma Knife procedures increased by 3.1% to 427 for the fourth quarter of 2020 from 414 in the same period of the prior year. Gross margin for the fourth quarter of 2020 decreased to $1,027,000 or 22.3% of revenue compared to gross margin of $1,441,000 or 30.1% of revenue for the fourth quarter of 2019. Selling and administrative costs increased by 22.5% to $1,052,000 for the fourth quarter compared to $859,000 for the fourth quarter of 2019. The period over period increase is due to increases in tax and added expense, stock based compensation and software related expenses. Operating loss for the fourth quarter of 2020 was $8,543,000 compared to operating income of $279,000 in the fourth quarter of 2019. Excluding the pretax write down of impaired asset in the quarter that totaled $8,264,000, the operating loss was $279,000. Net loss for the fourth quarter of 2020 was $6,231,000 or $1.01 per share, which includes the pretax write down of impaired assets of $8,264,000. This compares to net income for the fourth quarter of 2019 of $193,000 or $0.03 per diluted share. Adjusted EBITDA, a non-GAAP financial measure, was $2,538,000 for the fourth quarter of 2020 compared to $2,056,000 for the fourth quarter of 2019.
