Blue Cross Blue Shield of Texas wants to increase its individual health insurance plan premiums by an average of 57.3 percent to 59.4 percent in 2017.
The insurance company said in a statement: "It’s also important to understand the magnitude of the losses … experienced in the individual retail market over the past two years."
According The Associated Press, Blue Cross Blue Shield of Texas said that it lost $592 million in 2015 and $416 million in 2014.
The Houston Chronicle reported in 2015 that Blue Cross Blue Shield of Texas' Chicago-based parent company, Health Care Service Corp. (HCSC), "was sitting on a $9.9 billion surplus" when it previously requested and received a near 20 percent rate increase in Texas that went into effect in January.

HCSC CEO Patricia Hemingway Hall made about $11.7 million in 2014, including more than $10 million in bonuses, making her the sixth-highest earning insurance executive for that year.
However, HCSC said that it operated on "thin margins," and noted that it suffered a $282 million net loss for 2014.
HCSC said in a statement that it "remains strongly committed to a not-for-profit structure," and added: "We do not measure success by how much money we make. Instead, we set our sights on meeting the health care needs of our members and facilitating their use of the health care system."
