The nearly bankrupt U.S. Postal Service on Thursday reported losses of $57 million per day in the last quarter and warned it will miss another payment due to the U.S. Treasury, just one week after its first-ever default on a payment for future retiree health benefits.

From April to June, losses totaled $5.2 billion, up $2.1 billion from the same period last year.

The mail agency said it is being hurt significantly by mounting expenses for future retiree health benefits. Those expenses, mandated by Congress in 2006, made up $3.1 billion of the post office's quarterly loss, while workers compensation tacked on another $1.1 billion in expenses. The agency's operating loss was $1 billion, mostly due to declines in first-class mail.
