5. Cash and Cash Equivalents, Customer Concentrations, and Allowances for Credit Losses

Cash and Cash Equivalents

Highly liquid investments with a maturity of three months or less when purchased are considered to be cash equivalents. As of March 31, 2025 and September 30, 2024, there were no cash equivalents.

Cash deposit accounts are maintained at financial institutions and, at times, balances may exceed federally insured limits guaranteed by the FDIC. During 2023, the Company entered into enhanced deposit arrangements with two financial institutions in which monies are deposited through a brokerage account and are further placed on deposit by the broker amongst U.S. banks pre-screened by the broker in amounts per bank that do not exceed the individual $250 FDIC per depositor limit. The aggregate amount of all funds on deposit under these accounts was $14,804 and $14,515 as of March 31, 2025 and September 30, 2024, respectively. The Company also holds funds in various other bank accounts that may exceed FDIC insured limits. These uninsured amounts, in aggregate, were $2,949 and $5,194 as of March 31, 2025 and September 30, 2024, respectively. We have never experienced any material losses related to cash on deposit with banks.

Customer Concentrations

The Company’s single largest customer made up just over 10% of the Company’s consolidated revenues for the three and six-month periods ended March 31, 2025.

The Company has two customers that, in aggregate, made up approximately 26% and 27% of the consolidated accounts receivable balance as of March 31, 2025 and September 30, 2024, respectively. These two customers are offered extended payment terms due to the frequency and volume of our services that they utilize. Each maintains excellent creditworthiness and the Company has not historically experienced any losses related to these two customers.

Allowance for Credit Losses

The Company extends credit to its various customers based on evaluation of the customer’s financial condition and ability to pay the Company in accordance with the payment terms. An allowance for credit losses is recorded as a charge to bad debt expense where collection is considered to be doubtful due to credit issues. The Company adopted the methodology under ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), during the quarter ended December 31, 2023. The amendments in ASU 2016-13 replace the probable incurred loss impairment methodology underlying our previous allowance for doubtful accounts with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Under ASU 2016-13, an allowance is recorded with a corresponding charge to bad debt expense for expected credit losses in our accounts receivable including consideration of the effects of past, present and future conditions that may reasonably be expected to impact credit losses. The Company charges off uncollectible accounts against the allowance once the invoices are deemed unlikely to be collectible. The allowance for credit losses is reflected in the unaudited condensed consolidated balance sheet as a reduction of accounts receivable. The impact of the adoption of ASU 2016-13 was immaterial to the Company’s unaudited condensed consolidated financial statements.

As of March 31, 2025 and September 30, 2024, the allowance for credit losses was $133 and $144, respectively.

A summary of changes in this account is as follows:

Liabilities for Direct Hire Placement Falloffs

Direct hire placement service revenues from contracts with customers are recognized when the Company has met each of the criteria under Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606), including its performance obligations under the contracts. This generally occurs when the employment candidates accept offers of employment and have started their newly placed positions, less a provision for estimated credits or refunds to customers as the result of applicants not remaining employed for the entirety of the Company’s guarantee period (referred to as “falloffs”). The Company’s guarantee periods for permanently placed employees generally range from 60 to 90 days from the date of hire.

Charges for expected future falloffs are recorded as reductions of revenues for estimated losses due to applicants not remaining employed for the Company’s guarantee period. Liabilities for falloffs and refunds during the period are reflected in other current liabilities in the unaudited condensed consolidated balance sheets in the amounts of $59 and $102, as of March 31, 2025, and September 30, 2024, respectively. The corresponding charges included in the unaudited condensed consolidated statements of operations as reductions of direct hire placement service revenues were approximately $30 and $(14) for the three-month periods and $252 and $230 for the six-month periods ended March 31, 2025 and 2024, respectively.
