Maternity leave at a PEO

I'm about to be hired by a PEO in California, on behalf of my out-of-state employer (based in a U.S. territory, not a state). I'm planning on having my second child, say, a year after being hired, and I want to know whether the PEO or my "real" employer will be considered to be my employer for the purposes of qualification for unpaid leave under the FMLA (and/or other maternity-related federal or California laws). I can hope, at least, that my PEO will employ at least 50 people in my metro area, but with my real employer there's no chance. Which one is it?

Thanks

The PEO will be your employer. Their name will be the one on your paychecks.
