Re: Sentence analysis
Hi Noran,
Welcome to Using English. We're glad to have you.
The entire paragraphs is full of errors and I expect it was not written by a native speaker.
The sentence you highlight is no worse than some of the others, and I expect its intended meaning is "In some companies, the financial analysis is performed in-house" or "In some companies, financial analysis reports are prepared internally."
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
