AEG spent $24 million on Michael Jackson concerts.

AN accounting executive for AEG Live LLC testified on Monday that the company spent $US24 million ($24.52) producing Michael Jackson's ill-fated 'This Is It' concerts.

The tally involved expenses compiled through October 2009, roughly three months after the singer's death, said Julie Hollander, a vice president and controller of event operations for AEG Live.

Ms Hollander testified during the trial of a lawsuit filed by Jackson's mother against AEG claiming the company was negligent in hiring the doctor later convicted in the death of the pop star.

Budget documents shown in court indicated the company made no payments to the doctor, Conrad Murray.

AEG budgeted $US150,000 a month for Murray's treatment of Jackson, but the singer died of an anesthetic overdose before he signed Murray's agreement.

Hollander said Murray's contract was the only one she had ever seen in which an artist had to approve a contract for services on a tour. She believed Jackson's signature was required because of the personal nature of the doctor's services.

In total, Murray was projected to receive $US1.5 million in payments over the first few months of the This Is It tour, which was slated for 50 shows at London's 02 Arena.

Attorneys for Jackson's mother are trying to prove that AEG hired Murray and missed numerous red flags about the pop singer's health before his death.

AEG denies it hired Murray and says it bears no liability for Jackson's death.

Ms Hollander also testified that Jackson was responsible for 95 per cent of production expenses if his comeback shows were canceled. Budget documents indicated the production was more than $US2 million over budget.

Ms Hollander was the first AEG executive to testify in the lawsuit. The company's general counsel Shawn Trell began testifying on Monday.
