On the fourth day of the City Harvest trial, the prosecution tried to establish that the church was closely connected to an external company, Xtron Productions.

Third witness Koh Siow Ngea, a current director of Xtron, said he had been appointed to the position by the church. He said he was asked to take on the role by church pastor Tan Ye Peng, and he agreed to the position as he saw it as "a calling and a ministry" to the church.

But it emerged during the prosecution's questioning that he was not intimately aware of the goings-on in the company. He told the court that he "could not give details" on several documents, including financial statements and bond paperwork, even though these had his signature on them.

He also told the court that Xtron was "independent" from the church. However, he testified that it was the church that decided for Xtron to enter into an agreement with trustees of the church for the purchase of a property at The Riverwalk at Upper Circular Road, and it was also the church that was behind Xtron's decision to issue bonds. He was merely "informed" about these decisions, after they were made.

The church had also made decisions on who should be appointed as Xtron's full-time staff.

The trial surrounds six church leaders who are alleged to have funnelled $24 million into sham bond investments in companies such as Xtron, to further the career of church founder Kong Hee's pop-singer wife. They are then said to have devised a series of transactions amounting to $26.6 million to clear the engineered bond investments off the church's accounts.
