The former managing director said he relied on "people he trusted" telling him that lines of the prospectus were true.
"If [the statement] hadn't been signed off by the general manager of finance, I would have been concerned," Petricevic said.
After being told by Mr Cathcart to put himself in "an investor's shoes" and asked if someone would have taken comfort in the statement about the cash float, Petricevic said: "The prospectus needs to be read in total, not just by one line."
However, earlier in cross-examination the former director said he did not read the prospectus in full himself before signing it.
"I read the mark-ups. I didn't read the full prospectus," Petricevic said.
The trial continues today and is expected to run until March.
