Thank you, Len. With first quarter revenues up almost 93% over the same period last year, we demonstrated the leverage and flexibility of our business model to quickly scale to meet the growing demands of our customer base. Sequentially, quarterly revenue grew 31.8% to $9.7 million as we delivered our on backlog of orders. Gross margins reached 43.2% in the first quarter, a significant improvement from the 30.6% during the first quarter of 2016, but down from last quarter's 46.2% Gross margins tend to vary from quarter-to-quarter dependent on the mix of business. Operating expenses for the first quarter decreased sequentially as percentage of revenue from 30.1% to 25.4%, while increasing in absolute dollars by 11.3%. Selling and shipping for the quarter was 2.2% lower sequentially at $285,000 compared with $292,000. R&D declined to $70,000 from $129,000 in the fourth quarter of 2016, as our focus turned towards order execution versus development. Going forward, as Len mentioned, we plan to increase our investment in R&D as we develop new applications and expand our Tantaline business. General and administrative expenses for the quarter increased 17.7% to $2.1 million from the prior quarter as we began the installation and implementation of a new ERP system in order to more efficiently handle our growth. We are also in the process of scaling our workforce to support new and existing customers and applications that will be necessary to grow our Tantaline business as well as our core business. Overall, we saw an increase in personnel during the quarter as total employees reached 201 compared to 173 at the end of the fourth quarter. First quarter net income was $1 million compared to $770,000 in the fourth quarter and a loss of $338,000 a year ago. This resulted in earnings per diluted share of $0.16 compared with $0.12 in the fourth quarter and a loss of $0.05 in the first quarter of 2016. We expect this trend to continue as we deliver on our backlog of orders and continue to grow our business. During the quarter net accounts receivable increased to $8 million from $600,000 at the end of last quarter due to the timing of shipments and customer payments. As a result, we ended the quarter with $18.4 million in cash and cash equivalents, compared to $21.7 million at the end of last year. Working capital increased by $1 million to $21.5 million from $20.5 million at December 31, 2016. Backlog at the end of the quarter was $30.1 million, an increase of 8.3% from the end of last quarter. In closing, our first quarter financial performance showed substantial improvement both sequential and year-over-year, continuing the trend of the second half of last year. Looking at the rest of 2017, we expect this financial performance to continue as we fulfill orders, increase our core business and begin to add Tantaline to the mix. With that, I will turn the call over to the operator for questions. Thank you.
