Short-term invest.
Net receivables

Need help finding the amount of assets and equity for December 31, 2013.

First thing you have to find is equity for 2012. The basic accounting equation is:
Assets = Liabilities + Equity

Rewritten as:
Equity = Assets - Liabilities

Now you can find Equity for 2013. The formula is:
Ending Equity (2013) = Beginning Equity (2012) + Stock Issuances + Net Income - Cash Dividends

Now that you have Equity for 2013 you can solve for Assets for 2013. The formula is:
Assets (2013) = Liabilities (2013) + Equity (2013).
