Our Organization has a custom object known as "Intiatives" that has connections to multiple opportunities via a Lookup Field.  We use a Method (see below) to  calculate the value of all renewal opportunities attached to the Initiative object.

This functionality had been working fine until recently when we started receiving an error for a specific reocrd type:

"Error:Apex trigger OpportunityTriggers caused an unexpected exception, contact your administrator: OpportunityTriggers: execution of BeforeUpdate caused by: System.NullPointerException: Attempt to de-reference a null object: Class.OpportunityTriggersMgr.populateInitiativeRenewals: line 233, column 1"

(Line 233 has been underlined in the method below) The only thing changed has been some sharing rule adjustment. Unfortunately we no longer work with the developer who authored the below method.  Any help or guidance on this would be GREATLY appreciated!!!
