Doing a financial analysis of Enron and I have no idea how to answer this question?

1) Identify other financial resources (i.e. other than assets, etc.) at Enrons disposal and indicate the relevance of these resources to Enrons liquidity as of December 31, 2000. Address any concerns about off balance sheet obligations that will need to be met during the upcoming year. Also address any guarantees that Enron may be contingently liable for.
