| THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | |
| THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | NOTE 1 – THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION AND NATURE OF OPERATIONS Ridgefield Acquisition Corp. (“we”, “us”, “our”, “Ridgefield” or 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. GOING CONCERN AND LIQUIDITY At March 31, 2020, the Company had a working capital deficit and an accumulated deficit. The Company has continued to sustain losses from operations. In addition, the Company has not generated positive cash flow from operations. Management is aware that its current cash resources are not adequate to fund its operations for the following year. The Company cannot provide any assurances as to if and when it will be able to attain profitability. These conditions, among others, raise substantial doubt about the Company's ability to continue operations as a going concern. No adjustment has been made in the consolidated financial statements to the amounts and classification of assets and liabilities, which could result, should the Company be unable to continue as a going concern. The Company will be dependent upon the raising of additional capital through debt or the placement of our common stock in order to implement its business plan or merge with an operating company. The officers and directors have committed to advancing certain operating costs of the Company. The accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty. BASIS OF PRESENTATION The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission for the presentation of interim financial information, but do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. The accompanying financial statements should be read in conjunction with the December 31, 2019 consolidated financial statements that were filed in our annual report on Form 10‑K. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three-month period ended March 31, 2020 are not necessarily indicative of the results that may be expected for the year ended December 31, 2020. |

| RELATED PARTY TRANSACTIONS | NOTE 2 – RELATED PARTY TRANSACTIONS The Company previously occupied a portion of the offices leased by BKF Capital Group, Inc., on a month to month basis for a rental fee of $50 per month that was intended to cover administrative costs. Steven N. Bronson, the Company's Chairman, CEO, and majority shareholder, is also the Chairman, CEO and majority shareholder of BKF Capital Group, Inc.

There were no payments made to BKF during the three months ended March 31, 2020. Steven N. Bronson, the Company's Chairman, President, CEO, and majority shareholder has loaned the Company money to fund working capital needs to pay operating expenses.
