 quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data. |
| Level 3 – |     | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs.                                     |

The estimated fair values of accounts receivable, contract assets, accounts payable, accrued expenses, and indebtedness with unrelated parties approximate their carrying amounts due to the relatively short maturity or time to maturity of these instruments. Notes payable with related parties may not be arms-length transactions and therefore may not reflect fair value.

The fair value of the New Convertible Debentures are measured at each reporting date in accordance with ASC 820-10, Fair Value Measurement, using a Monte Carlo simulation model. This model incorporates Level 3 inputs, including, current stock price, stock price volatility (historical and implied), risk-free interest rate (U.S. Treasury rates) and expected term to maturity. The fair value measurement is classified as Level 3 in the fair value hierarchy due to the use of unobservable inputs. At March 31, 2024 the following assumptions were used in to estimate the fair value of the New Convertible Debentures: stock price of $ 0.3195, a risk free rate of 4.51%, implied volatility of 123% and a remaining term of 2.44years.
