United Products Inc. has the following balance sheet:

Current assets	$5,000	Accounts payable	$1,000
		Notes payable	1,000
Net fixed assets	5,000	Long-term debt	4,000
		Common equity	4,000
Total assets	$10,000	Total liabilities and equity	$10,000

Business has been slow; therefore, fixed assets are vastly underutilized. Management believes it can double sales next year with the introduction of a new product. No new fixed assets will be required, and management expects that there will be no earnings retained next year. What is next years additional funding requirement?
