The department, if I've found it correctly on the sheet, has very few students enrolled in it but logs tens of thousands of credit hours a year: this is presumably mostly students taking a foreign language course as part of general education requirements. I imagine that's where the bulk of the tuition income allocated to the department is coming from.
Presumably the idea is something like, if we axe the department, we dump 16 tenure-track and 32 total FTEs and something like 60 students lose their program: good trade. You just write off the linguistics and TESOL programs completely along with the handful of foreign language majors, and you figure that you can give out uhhhh... Duolingo credits to the students in other programs that cared about their foreign language/lit classes and keep them around.
Of course you're abandoning the pretense of really being a university and offering well-rounded education and broad opportunities and all that... but at least you can keep all the administrators.
