In late 2005, ATA secured $100 million in committed financing from the firm of MatlinPatterson, and Southwest's original deal with ATA was modified such that Southwest no longer retained the 27.5% stake (or any other financial interest), in ATA. The codeshare arrangement was expanded, with some internal controversy, to include all of ATA's domestic destinations and more than 60 of Southwest's 63 destinations. In 2006, Southwest's pilot union approved a codeshare sideletter to their contract with limitations on the growth of this and other codeshare agreements. While these restrictions today are minor, outsourcing remains a growing concern in the unions' current contract negotiations.
