The World Bank has finally calculated Thailand's expected cost of rehabilitation and needed flood prevention measures in the wake of the nation's worst floods in 50 years.

The figure isn't pretty: $2.1 billion.

Dow Jones reports that roughly one-third of that World Bank recovery figure is expected to come from the government. The flood damage is also predicted to shave 1.2 percent from 2011's GDP growth, which will likely land at about 2.4 percent.

The good news? The disaster won't compel many business to relocate, according to the World Bank, which still regards Thailand as "an attractive investment destination," according to Asia One.
