Subsequent Events [Abstract]
Subsequent Events	Note 16 – Subsequent Events On January 13, 2012 the Company, the Staff of the NYPSC and other intervenor parties filed a Joint Proposal (the “Proposal”) with the NYPSC to resolve all issues in the rate case. The Proposal provides for revenue increases to Corning’s rates in the first year (May 1, 2012 to April 30, 2013) of $944,310; in year two (May 1, 2012 to April 30, 2014) of $899,674; and in year three (May 1, 2014 to April 30, 2015) of $323,591. The cumulative revenue increases over the three years total $4,955,869. The Proposal also provides the Company the opportunity to earn $545,284 from local production before sharing, a 118% increase from the $250,000 allowed today. The Proposal also provides for property tax reconciliation, treatment of future local production investment, allocations to the Company’s new Leatherstocking operations, consolidation of the three divisional rate tariffs into a single rate tariff and recovery of forecasted capital and operation and maintenance costs for the period May 1, 2012 to April 30, 2015. The rates are based on a 9.5% return on equity. The Proposal will be reviewed by the Administrative Law Judges presiding in the rate case, who will then recommend approval or disapproval of the Proposal to the NYPSC. The NYPSC is expected to render a decision in April 2012, with rates becoming effective May 1, 2012. On January 27, 2012, the Company completed a private placement of its common stock, par value $5.00 per share, pursuant to the terms of a Purchase Agreement, dated as of January 23, 2012, between the Company and the Article 6 Marital Trust under the First Amended and Restated Jerry Zucker Revocable Trust dated April 2, 2007 (the “Purchaser”). The 138,889 shares of common stock (the “Common Stock”) issued pursuant to the Purchase Agreement were sold at a per share cash price of $14.40 and raised gross proceeds of $2 million for the Company which will be used for general corporate purposes. In connection with the private placement, the Company entered into a Registration Rights Agreement, dated as of January 23, 2012, which grants the Purchaser certain demand and piggy-back registration rights with respect to the Common Stock. The issuance and sale of the Common Stock was not registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and the shares may not be sold in the United States absent registration or an applicable exemption from registration requirements. The Common Stock was offered and sold in reliance on the exemption from registration afforded by Section 4(2) of the Securities Act and corresponding provisions of state securities laws.
