Their commitment and dedication continue to deliver excellent results for our customers, provide increasing opportunities for our employees, and bring crucial services to our communities. Careful discipline and great execution resulted in quarterly EPS that doubled compared to the same quarter last year. In addition to increased revenue and earnings, we also achieved over $400 million of quarterly cash flow.”
