Good example. You can just say, “Syria is in tatters” instead of “the Syrian country”

A few things here. First, you have an agreement problem. The first part says, “After being unable to refinance,” so you have to think of who “is unable to refinance” and that is the company. So the second half of your sentence has to start with “the company” – instead, you started it with “the company’s plans.” But the plans weren’t unable to refinance, the company was. So you’d have to rearrange this and make “the company” the subject of the second half: “After being unable to refinance its loans due to the rapid increase in interest rates, the company found its plans to restore its solvency were in tatters.”
