Ann: Thunderbird Construction Over 75% Complete, page-21

The $27m is well and truly covered by the existing contingencies and cost overrun facility. In fact, even after the recently reported increase KMS still has in excess of $50m available in remaining cost overrun/contingencies.

With only 25% of construction now remaining, and approximately half that covered by the fixed price contract with GR Engineering or already spent, I think SFX is in a pretty healthy position right now. They'd have to see cost blowouts of 100% on the remaining construction in order to use up their remaining available contingency.
