FNDE
Schwab Fundamental Emerging Markets Equity ETF
stock NYSE ETF

I think it's pretty solid.
Your US portion has Large-Cap Blend (IVV), Large-Cap Growth (SPMO), and Large-Cap Value (SCHD). You should consider adding Small-Cap Value (AVUV) to round it out. If you replaced your SCHD with FNDX (The US version of your FNDF), it would be identical to my US portfolio.
You could complement your Developed portion with Small-Caps (AVDV), as well as add some Emerging Markets with FNDE and/or AVES.

At the present time, TIPS bonds real yield is pretty high. Tipswatch.com had a note on it just today. You could buy a TIPS bond which matures in 17 years. But I think you should have some stocks too, you do have ti e to grow the pile. I like FNDX FNDA FNDE FNDF at present.. the Schwab Fundamental Index ETFs. I'm 65, retired. I've seen many market conditions. Generally don't take advice from people who weren't investing prior to 2009. They have no real bear market experience.
