Thank you, Hermann, and thank you all for joining us here today in this call. I would like to now give you an overview of the financial results of last year and an outlook for 2021. Given that this is my first conference call as CFO at Biofrontera, I would like to briefly introduce myself before we move on to the business part. As you probably already know, I've been Chief Financial Officer of Biofrontera since March 1 of this year, which is just under 6 weeks. Before that, after completing my studies in the U.S., I was CFO at brillen.de, HRS, Astaro [ph], which was acquired by SOPHOS and also two publicly listed companies, Intershop Communications AG and Poet Holdings, Inc. The latter, like Biofrontera, was listed in Germany as well as in the U.S. So my capital market experience therefore spans both sides of the Atlantic, which I will also be bringing to Biofrontera. I must admit that I could hardly have chosen a better time to be appointed CFO, I mean, which CFO is not delighted to start a company -- in a company where a capital increase has just been successfully completed, and the financing of the corporate strategy secured for the time being. Turning now to the key financial figures. Hermann just -- has already discussed the revenue developments, our key market and our key markets in the pandemic year 2020. To better understand the full extent of the impact of the pandemic and thus, our financial results, let me reiterate in more detail. As we've just heard, the corona crisis has led to a declining number of treatments and thus to sharp declines in sales, particularly in our key sales markets, the United States. On March 20 of last year, i.e., shortly after the pandemic spread of the virus became known, the company announced that it was taking comprehensive preventative measures to reduce and control costs. As such, short-term work was introduced for all employees in Germany until the end of July of 2020. Similar measures were implemented in the subsidiaries in Spain and the U.K. U.S subsidiary Biofrontera Inc. had also initiated significant cost cutting measures. There, the workforce was significantly reduced and a furlough program was introduced under which all employees were required to take temporary unpaid leave. In addition, the members of the Management Board and the Supervisory Board of Biofrontera AG, the parent and the management of Biofrontera Inc., voluntarily waived a part of their compensation. Furthermore, among other things, cost and non essential training and continued education were reduced in the reporting year. While these cost saving measures were in effect, the company was able to still ensure full compliance with all legal requirements in medical and capital market regulatory respect without interruption as well as meeting all continuous disclosure obligations. Due to COVID-19 crisis, the continued challenging business environment has impacted the valuation of some of the company's assets and liabilities. During the crisis, the sales strategy in the U.S market has focused on our flagship product Ameluz and the target that relaunch to improve the positioning of our in-licensed product Xepi has been delayed. The reduced sales of Xepi led to a reassessment of the medium term business and earnings prospects for Xepi, and thus to an impairment of Xepi -- of the Xepi license in the first quarter of 2020. To a minor extent, inventories were written down as of December 31, 2020 due to an anticipated expiration of shelf life. Beyond this, no significant risks have arisen in relation to financial instruments, particularly no extraordinary write downs of receivables. So what does it actually mean for our results? On the cost side, especially for G&A expenses as well as sales expenses, we saw a significant reduction compared to the previous year due to cost saving measures introduced in the COVID-19 pandemic. G&A expenses amounted to €9.2 million in fiscal 2020 compared to €16.3 million in the previous year. This was mainly due to the aforementioned cost saving measures as well as lower legal and consulting expenses of just under €2 million compared to €6.9 million in 2019. Sales and marketing expenses amounted to €20.5 million, a significant reduction compared to previous year's figure of €28.9 million. The effects of the cost saving measures implemented were offset by a noncash impairment of Xepi -- of the Xepi license in the amount of €2 million. €4.8 million in research and development costs which also include the expenses for maintaining regulatory approvals were the only item of expenditure in the reporting period that was slightly above the previous year's level of €4.6 million. At €7.6 million in 2020, the loss from operating activities improved by €15.8 million compared to previous year loss of €23.4 million, mainly as a result of cost cutting measures and the effects on the first time consolidation of Cutanea included in the previous -- in previous year's figures. What is particularly encouraging and I'd like to point your attention to is that we've reached the operating breakeven point at group level for the first time in the fourth quarter of 2020. Other income and expenses totaled €2.4 million in the reporting period compared to the previous year income of €21.2 million, whereby again, the previous year figures includes one-time effect from the acquisition of Cutanea Life Sciences, Inc., amounting to €21 million. In 2020, translation expenses of €3.6 million were included compared to a currency translation gain of €0.3 million in 2019. As a result, our loss before tax for 2020 was €12.6 million compared to a loss of €4.8 million in 2019. I would now like to turn briefly to the current development of our business, which I'm pleased to report its showing [technical difficulty] in the first quarter of 2021, based on the preliminary sales figures. Thereafter, I will turn to the guidance for the current year. As already reported last Thursday, when we published the preliminary unaudited revenue numbers for Q1, revenue in the first quarter of this year has not yet reached the level of the previous period and was approximately €5.6 million compared to €6.5 million in 2019. While revenues in Germany maintain -- remained relatively stable compared to the previous year. Revenue in the U.S., in January and February were still significantly lower than last year. The pandemic became noticeable in our revenues from the second half of March 2020 onwards. And from this point on, the significant upturn was evident in the U.S this year compared to 2020. In March, we were able to increase our sales by approximately 46% year-on-year indicating a significant recovery of the situation in the U.S., which is probably also the [technical difficulty] and destination. We're confident in the continued recovery and look forward to the coming year even more than in fall of last year before the positive clinical results of the corona vaccines. Turning on to the outlook and guidance for our key financial indicators. First of all, I would like to emphasize that even after a year of exposure to the coronavirus crisis, it is still difficult to assess global business developments during the pandemic. The forecast for the full year 2021 reflect our assessment of the timing and speed of recovery from the pandemic. We expect that due to the vaccination programs, the pandemic will slowly subside in our most important markets, allowing growth momentum to become apparent and show results in the second half of 2021. At group level, we expect revenue from product sales between €25 million to €32 million in fiscal 2021. I would like to emphasize once again that our sales and therefore business activities are highly dependent on the further course of infections and the associated easing of containment measures. I would also like to point out that starting with 2021 reporting year, EBITDA and EBIT will be introduced as key performance indicators in our reporting. Both have been established internationally as target metrics and will replace the previously reported KPI results from operation activities. As a reminder, group EBITDA includes earnings before interest, taxes, depreciation of tangible and amortization of intangible assets. EBIT includes earnings before interest and taxes. These KPI indicators are suitable for describing and comparing operating performance as non-operating fluctuation variables, for example, valuation adjustments and amortization of acquired assets are not included. Based on the assumptions mentioned above, we expect that EBITDA loss between €11 million and €14 million and an EBIT loss between €13 million and €16 million at group level for 2021. And on the last key indicator, liquidity. From today's perspective, considering the earnings expectations with the cash and cash equivalents of €16.5 million as of December 31, 2020, and the capital increase carried out in February of 2021 with gross proceeds of around €24.7 million, the group is sufficiently funded for the coming 12 months, at least. That pretty much sums it up for my part. And at this point, I'd like to hand over back to Hermann, for some concluding remarks.
Hermann Lübbert: Yes. Thank you, Ludwig. Now before we turn to the to the questions, I would like to comment briefly on the status of the various lawsuits. Two such lawsuit is ongoing, and unfortunately we were not able to reach an agreement, so the next step will be to enter into the actual trial of the case in front of a jury. The court has already set a preliminary date for this jury trial, which is scheduled to begin at the end of November 2021. However, this may be further delayed. We take the clear position that these lawsuits are without merit, and intend to do defend ourselves vigorously. Of course, this does not guarantee that we will be successful in doing so. However, DUSA's request for an injunction to stop our sales activities has already been largely rejected by the court, with the court merely stating that Biofrontera may not use any documents or information derived from documents that originated from do so. Contrary to German conventions, legal costs in the U.S are generally not borne by the losing side. So that Biofrontera must continue to expect substantial legal costs in the coming year, which will not be reimbursed to the company even if the outcome of the trial is positive for Biofrontera. On the other hand, we dropped our own lawsuit against DUSA last year, as the accused business practices were largely discontinued by DUSA, following an investigation of the Department of Justice and the legal costs incurred would therefore not -- therefore have been disappropriate to the added value. The ruling of the Cologne Higher Regional Court regarding the action for annulment filed by the Balaton group against the resolutions of the 2017 Annual General Meeting was set aside by the Federal Court of Justice and referred back to the Cologne Higher Regional Court for a new hearing and decision. The decision on the action for annulment against resolutions of the 2019 Annual General Meeting is still pending. Our lawsuit against the Balaton group and Mr. Zours in New York is currently suspended due to the mediation process between the two parties. The ruling of the Cologne Higher Regional Court regarding the action for annulment filed by the Balaton group -- second in the mediation process with the Deutsche Balaton group, we asked the U.S court by mutual agreement for further extension until the end of August 2021, which was granted. Moving the Annual General Meeting to August is already a result of these discussions. The pandemic, but also the uncertainty surrounding our shareholder structure, did not do our share price any good. Despite the successfully completed significantly oversubscribed capital measures, the share price has not yet been able to discover sustainably. However, we would like to solicit our confidence that we have strategically positioned Biofrontera in the best possible way to generate sustainable growth. The pandemic has certainly hit us hard on the sell side in the USA, so that we have not yet achieved the planned sales goals and thus also the financial independence of Biofrontera. However, we have not abandoned the path to this goal, but have merely had to slow down the pace so that we remain fully convinced both of our products and of the sales activities that aim to tap the enormous potential. We expect a significant recovery of the general economic situation in the course of this year and subsequently want to continue our steep growth from 2016 to 2019 in a seamless manner. Finally, we would like to express our sincere thanks to our employees, our supervisory board and our shareholders for their commitment, their support and their loyalty to the company. I would now like to open the line for questions. Thank you.
