Great Grey EUPAC Trust Class R1 (GEPABX) for international exposure in work 401k

Has anyone ever heard of this investment before for international coverage in a work sponsored 401k? It holds about 348 stocks outside of the US and the expense ratio is noted at 0.41. I am very heavy in large cap American companies and I am looking to diversify a bit. I would allocate 30% to this fund but would like feedback from anyone and input. The other 70% of my allocation will be to a low cost S&P fund, specifically Fxaix. Thank you!
