General and administrative expenses went down by 26% year-over-year, and stood at $2,760,666 at year-end 2013, ESP Resources said. This decrease was due to a reduction in the number of employees, the company added. The decrease was also due to lower international business development costs, the company said.

Regarding net losses, at year-end the amount was $5,237,777, the company said, noting that this was higher than the amount at year-end 2012. This was due to discontinued operations, the company said.
