In January 2019, we entered into an agreement to acquire the business of our distributor in South Korea. The transaction is expected to close in April 2019.

In February 2019, we announced a share repurchase program for calendar-year 2019 authorizing the repurchase of up to 800,000 shares of our common stock from time to time on the open market or in privately-negotiated transactions as permitted under the Securities Exchange Act of 1934 Rule 10b-18. The number of shares to be repurchased and the timing of such transactions will depend on a variety of factors, including market conditions. This share repurchase program is expected to be completed by December 31, 2019. Our previously-authorized share repurchase program expired on December 31, 2018.
