A Citadel holder group will fight Great Western.

Hecco Ventures, an investment group with an 8.8% stake in Citadel Holding Corp., parent of Fidelity Federal Savings & Loan Assn. of Glendale, said it will oppose Great Western Financial Corp.’s bid to acquire Citadel in a stock swap. The group, led by Los Angeles theater owner Michael Forman, said the Great Western offer is unfair to Citadel shareholders because it undervalues the thrift’s stock. Hecco said the group will seek other potential suitors.
