The Castillo Products Company was started in 2008. The company manufactures components for personal digital assistant (PDA) products and for other handheld electronic products. A difficult operating year, 2009, was followed by a profitable 2010. However, the founders (Cindy and Rob Castillo) are still concerned about the venture's liquidity position and the amount of cash being used to operate the firm. Following are income statements and balance sheets for the Castillo Products Company for 2009 and 2010.

A. Use year-end data to calculate the current ratio, the quick ratio, and the NWC to-total-assets ratio for 2009 and 2010 for Castillo Products. What changes occurred?

C. Convert the annual cash build and cash burn amounts calculated in Part B to monthly cash build and cash burn rates. Also indicate the amount of the net monthly cash build or cash burnrate.
