Imported Maya 2014 animation won't loop

I have a simple animation that I have imported from Maya 2014 and have hooked up to a state in my mecanim animation controller. While running the game, I can see the bar on the state repeatedly fill to show looping, but the animation only plays the first time through.

If I look at the animation clip, the loop pose option is not checked, but that property window is grayed out. I've read that this is because the animation was imported from Maya, but I can't figure out what to change in Maya that would impact that flag.

I'm also not 100 percent sure how to access that specific animation clip through the script that hooks up to my animation controller, but I'd prefer to simply author the animation correctly in the first place anyway if I can.

Thanks in advance for the assistance!
