A proposed $13.2 million settlement of claims related to last year's Indiana State Fair stage collapse stalled Wednesday when one of the companies involved determined that not enough claimants had agreed to the settlement to meet “minimum participation requirements.”

Greenfield, Ind.-based Mid-America Sound Corp. and Knoxville, Tenn.-based James Thomas Engineering Inc., named as defendants in suits stemming from the Aug. 13, 2011, stage collapse, had agreed to provide $7.2 million in settlement funds to be added to $6 million in supplemental settlement funds approved by the Indiana Legislature.

The companies had agreed to pay the $7.2 million in exchange for a sufficient number of claimants releasing them from lawsuits. Ultimately, 51 of 62 stage collapse victims had agreed to the settlement by the Aug. 1 deadline.

But Mid-America Sound said in a statement Wednesday, “The state's proposal required a sufficient ratio of claimants from the largest claims categories to accept the settlement in order for it to become effective,” adding that the condition had not been met.

In a statement Mid-America Sound said it was "hopeful that future efforts seeking to resolve the claims associated with the tragic events of Aug. 13, 2011 are successful to bring full and satisfactory resolution to the claims now pending."

In a statement Wednesday, Indiana Attorney General Greg Zoeller said the state would move forward with plans to distribute its $6 million portion of the settlement “and will seek to facilitate discussions between claimants and the second company, JTE.” The state had previously paid out $5 million to stage collapse victims.

Seven people were killed last year when the stage roof and scaffolding collapsed during a severe storm prior to a concert by the country duo Sugarland.

Earlier this year, reports examining engineering reasons for the stage collapse and emergency preparedness at the Indiana State Fair determined that the stage lacked adequate lateral support and that the state fair organization suffered from the lack of defined emergency decision-making and information sharing procedures at the time of the stage collapse.
