Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	NOTE 1 - NATURE OF OPERATIONS AND BASIS OF PRESENTATION (A) NATURE OF OPERATIONS Ridgefield Acquisition Corp. (the "Company") was incorporated under the laws of the State of Colorado on October 13, 1983. Effective June 23, 2006, the Company was reincorporated under the laws of the State of Nevada through the merger of the Company with a wholly-owned subsidiary of the Company. Since July 2000, the Company has suspended all operations, except for necessary administrative matters. The Company has no principal operations or revenue producing activities. The Company is now pursuing an acquisition strategy whereby it is seeking to arrange for a merger, acquisition or other business combination with a viable operating entity. (B) BASIS OF PRESENTATION The accompanying unaudited interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules and regulations of the United States Securities and Exchange Commission for interim financial information. The financial information as of December 31, 2010 is derived from the audited financial statements presented in the Company's Annual Report on Form 10-K for the years ended December 31, 2010 and 2009. The unaudited interim financial statements should be read in conjunction with the Company's Annual Report on Form 10-K, which contains the audited financial statements and notes thereto, together with the Plan of Operations for the year ended December 31, 2010. Certain information or footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a comprehensive presentation of financial position, results of operations, or cash flows. It is management's opinion, however, that all material adjustments (consisting of normal recurring adjustments) have been made which are necessary for a fair financial statement presentation. The interim results for the three months ended September 30, 2011 are not necessarily indicative of results for the full fiscal year. INCOME PER COMMON SHARE Basic income (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding during the year. Diluted income per common share is calculated by adjusting outstanding shares, assuming conversion of all potentially dilutive convertible equity instruments consisting of options. There is no difference in the calculation of basic and diluted income per share for 2011 and 2010, respectively. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NEW ACCOUNTING STANDARDS There are no new accounting standards that are expected to have a significant impact on the Company.
