DUBAI, May 11 (Reuters) - Abu Dhabi sovereign investor Mubadala is expected to raise $1.5 billion from a sale of bonds maturing in 10-1/2 and 30 years, a bank document showed on Thursday.

Initial price guidance was 140 to 150 basis points (bps) over current 10-year U.S. Treasuries for the 10-1/2-year tranche and about 180 bps over UST for the 30-year portion, which is a Formosa tranche, the document on the sale showed.

Formosa bonds are debt sold in Taiwan by foreign borrowers and are denominated in currencies other than the Taiwanese dollar.

Abu Dhabi Commercial Bank ADCB.AD, BNP Paribas BNPP.PA, Citi C.N, First Abu Dhabi Bank FAB.AD, JPMorgan JPM.N and Standard Chartered STAN.L are joint global coordinators. Barclays BARC.L, Credit Agricole CAGR.PA, Emirates NBD Capital ENBD.DU, Mizuho 8411.T, Natixis and SMBC Nikko 8316.T are also on the deal.

Mubadala has $1.8 billion in debt maturing this year, including $1.4 billion in bonds, an investor presentation reviewed by Reuters showed. Another $3 billion in debt, including $1.8 billion in bonds, is due year.
