Summary of significant accounting policies | 2. Summary of significant accounting policies Principles of consolidation . The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, all of which are inactive. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”), 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 the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Cash and cash equivalents Cash equivalents represent short-term, highly liquid investments, which are readily convertible to cash and have maturities of three months or less at time of purchase. Cash equivalents, which are carried at fair value or amortized cost, as applicable, consist of holdings in a money market fund and in U.S. Treasury Bills. Cash and cash equivalents amounted to approximately $125,000 and $90,000 at December 31, 2023 and 2022, respectively. Investment Valuation The Company’s investments in marketable securities consist of investments in debt securities which are U.S. Treasury bills, and equity securities which are mutual funds. The Company carries its investments at fair value. Fair value is an estimate of the exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants (i.e., the exit price at the measurement date). Fair value measurements are not adjusted for transaction costs. A fair value hierarchy provides for prioritizing inputs to valuation techniques used to measure fair value into three levels: Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 Inputs other than quoted market prices that are observable, either directly or indirectly, and reasonably available. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the Company. Level 3 Unobservable inputs. Unobservable inputs reflect the assumptions that the Company develops based on available information about what market participants would use in valuing the asset or liability. An asset or liability's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Availability of observable inputs can vary and is affected by a variety of factors. The Company uses judgment in determining fair value of assets and liabilities and Level 3 assets and liabilities involve greater judgment than Level 1 or Level 2 assets or liabilities. As of December 31, 2023 and 2022, the Company held $2,409,000 and $4,130,000, respectively, in U.S. government debt securities, and $735,000 and $0 in equity securities which are mutual funds, respectively. U.S. government securities are valued using a model that incorporates market observable data, such as reported sales of similar securities, broker quotes, yields, bids, offers, and reference data. Certain securities are valued principally using dealer quotations. Money market and mutual funds are valued at the closing price reported by the fund sponsor from an actively traded exchange. U.S. government securities are categorized in Level 2 of the fair value hierarchy, depending on the inputs used and market activity levels for specific securities. Mutual funds are categorized in Level 1 of the fair value hierarchy, depending on the unadjusted quoted prices in active markets for identical assets. The U.S. government debt securities, which , are reported as Cash and cash equivalents, and those with longer maturities are reported as investments, on the consolidated balance sheets as of December 31, 2023 and 2022. Short-term investments in marketable securities have a stated maturity of twelve months or less from the balance sheet date. These securities are considered as available for sale and are reported at fair value. For debt securities, unrealized gains and losses are recorded net of tax as a component of Accumulated other comprehensive income within stockholders' equity. Declines in market value from the original cost deemed to be "other-than-temporary" are charged to Interest and other income, net, in the period in which the loss occurs. The Company considers both the duration for which a decline in value has occurred and the extent of the decline in its determination of whether a decline in value has been “other than temporary.” Realized gains and losses are calculated based on the specific identification method and are included in Interest and other income, net, in the Consolidated Statement of Operations. The Company follows the guidance in ASC 321, “Investments – Equity Securities” (“ASC 321”) for its investments in equity securities with unrealized and realized gains and losses recorded as Interest and other income, net, on the Consolidated Statement of Operations. The following table presents the Company’s financial instruments measured at fair value on a recurring basis (in thousands): Fair Value Measurements as of December 31, 2023 Total Quoted Prices Significant Significant Investments in U.S. Treasury bills $ 2,409 $ - $ 2,409 - Investments in Mutual Funds 735 735 - - Total $ 3,144 735 $ 2,409 - Fair Value Measurements as of December 31, 2022 Total Quoted Prices Significant Significant U.S. Treasury bills $ 4,130 $ - $ 4,130 - Investments in debt and equity securities as of December 31, 2023 are summarized by type below (in thousands).

There were no amounts reclassified from accumulated other comprehensive income to interest income and other income for the year ended December 31, 2022. Changes in the accumulated other comprehensive income balance, net of income taxes, relates solely to net unrealized gain on available-for-sale debt securities for the year ended December 31, 2023 is as follows: Balance at December 31, 2022 $ 32 Amounts reclassified from accumulated other (6 ) 26 Net current-period other comprehensive income 14 Balance at December 31, 2023 $ 40 There were no unrealized or realized gain (loss) for equity securities for the year ended December 31, 2023. The Company may be exposed to credit losses through its available-for-sale investments. An available-for-sale security is impaired when its fair value declines below its amortized cost basis. Unrealized losses resulting from the amortized cost basis of any available-for-sale debt security exceeding its fair value are evaluated for identification of credit losses. When evaluating the investments for impairment at each reporting period, the Company reviews factors such as the extent of the unrealized loss, historical losses, current and future economic market conditions, and financial condition of the issuer. As of December 31, 2023, the Company has not recognized an allowance for expected credit losses related to its available-for-sale securities as the Company has not identified any unrealized losses for these investments attributable to credit factors. Investment in undeveloped land The Company owns certain non-strategic assets, including an investment in land and certain flowage rights in undeveloped property (the “properties”) primarily located Killingly, Connecticut. The properties were fully impaired as of December 31, 2018. Per share data Loss per share for the year ended December 31, 2023 and 2022, respectively, is calculated based on 20,620,711 and 20,504,457 weighted average outstanding shares of common stock, including weighted average issuable shares of 182,905 at December, 31 2022. Stock-based compensation Stock-based compensation cost for employees is measured at the grant date based on the fair value of the award and is recognized as an expense on a straight-line basis over the requisite service period, which is generally the vesting period. In accordance with ASU 2016-09, the Company has made the accounting policy election to continue to estimate forfeitures based upon historical occurrences. See Note 7 to the Consolidated Financial Statements for further information regarding the Company’s stock-based compensation assumptions and expense. Income taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to carryforwards and to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The accounting for uncertain tax positions guidance requires that the Company recognize the financial statement benefit of a tax position only after determining that the Company would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company recognizes interest and penalties on income taxes, including those related to uncertain tax positions as interest and other expenses, respectively. The Company had no income tax uncertainties at December 31, 2023 and 2022. Concentrations of credit risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and investments. Investments in cash and money market funds are insured up to $250,000 per depositor, per insured bank. Investments in U.S. Treasury Bills are insured up to $500,000. For the years ended December 31, 2023 and 2022, a substantial portion of the Company’s investments in cash, U.S. Treasury Bills, and mutual funds are in excess of these limits. |
