Liquidity and Capital Resources
During the three months ended September 30, 2022, the Company utilized a portion of its cash balance at June 30, 2022 ($12,365,000 of $41,730,000) to fund operations ($1,965,000) and to purchase marketable securities and other investments ($10,028,000) and property, plant and equipment ($372,000). The Company believes its current working capital, cash flows from operations and its revolving credit agreement will be sufficient to fund the Company’s operations through the next twelve months.
Accounts receivable at September 30, 2022 decreased by $7,876,000 to $21,342,000 as compared to $29,218,000 at June 30, 2022. This decrease is primarily the result of the higher sales volume of equipment during the quarter ended June 30, 2022, which is typically the Company’s highest, as compared to the quarter ended September 30, 2022.
Inventories, which include both current and non-current portions, increased by $14,051,000 to $63,837,000 at June 30, 2022 as compared to $49,786,000 at June 30, 2022. The increase was due primarily to higher costs of component parts and freight-in as well as a build-up of inventory of the Company’s radio products in order to mitigate potential supply chain interuptions of these products.. The increase was also due to the ongoing shortages of certain component parts and the Company purchasing large quantities of these hard to source component parts when they become available.
Accounts payable and accrued expenses, not including income taxes payable, decreased by $645,000 to $23,980,000 as of September 30, 2022 as compared to $24,625,000 as of June 30, 2022. This decrease is primarily due to a decrease in the Company’s accrued refund liability, which is explained in Note 2 to the Notes to the Company’s Consolidated Financial Statements, and a decrease in accrued annual bonuses and commissions as partially offset by an increase in accounts payable which relates to the increase in invertory discussed above.
As of September 30, 2022 and 2021, long-term debt consisted of a revolving line of credit of $11,000,000 (“Revolver Agreement”), with no amounts outstanding, which expires in June 2024. The revolving credit facility contains various restrictions and covenants including, among others, restrictions on borrowings and compliance with certain financial ratios, as defined in the agreement. The Company’s long-term debt is described more fully in Note 8 to the condensed consolidated financial statements.
As of September 30, 2022 the Company had no material commitments for capital expenditures or inventory purchases other than purchase orders issued in the normal course of business.
ITEM 3: Quantitative and Qualitative Disclosures About Market Risk
The Company's principal financial instrument is long-term debt (consisting of a revolving credit facility) that provides for interest based on the prime rate or LIBOR as described in the agreement. The Company is affected by market risk exposure primarily through the effect of changes in interest rates on amounts payable by the Company under these credit facilities.
All foreign sales transactions by the Company are denominated in U.S. dollars. As such, the Company has shifted foreign currency exposure onto its foreign customers. As a result, if exchange rates move against foreign customers, the Company could experience difficulty collecting unsecured accounts receivable, the cancellation of existing orders or the loss of future orders. The foregoing could materially adversely affect the Company's business, financial condition and results of operations. We are also exposed to foreign currency risk relative to expenses incurred in Dominican Pesos ("RD$"), the local currency of the Company's production facility in the Dominican Republic. The result of a 10% strengthening or weakening in the U.S. dollar to the RD$ would result in an annual increase or decrease in income from operations of approximately $868,000.
ITEM 4: Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management to allow timely decisions regarding required disclosure.
