Sales, gross profit, and net profit, our key performance indicators all were higher, and reflect excellent execution from our team, as we complete existing projects and add on new projects. Sewage treatment systems revenue was up over 20% for the year, and our two largest projects, in Lianjiang and Wuyishan are progressing through Phase 2, collectively with approximately $23.2 million in contract revenue to be recognized in coming quarters.
