I worked for a company that pulled a lot of LIFO tricks on its books. We struggled for a long time but our statements did a really good job of hiding this fact.
I knew what they were up to and I even participated in it to a certain extent. I didn't feel great about it but I was conflicted. I really needed that job, and if the company looked like it was struggling it could start to loose contracts and investors. I was perpetuating a lie because I benefited from it.
In the end the company went under anyway. All the accounting tricks in the world could not have saved it towards the end. It was a shame, they were not bad to work for generally, they just had some shady ideas about what it took to stay in business.
