A material weakness in our internal controls could have a material adverse effect on us. Effective internal controls are necessary for us to provide reasonable assurance with respect to our financial reports and to mitigate risk of fraud. If material weaknesses in our internal controls are discovered or occur in the future, our consolidated financial statements may contain material misstatements and we could be required to restate our financial results, which could materially and adversely affect our business and results of operations or financial condition, restrict our ability to access the capital markets, require us to expend significant resources to correct the weaknesses or deficiencies, subject us to fines, penalties or judgments, harm our reputation, or otherwise cause a decline in investor confidence.
The loss of key employees and difficulties in hiring and retaining employees could adversely affect our business. We depend on the contributions and abilities of our senior management and other key employees. Our Company has grown significantly in recent years and our management remains concentrated in a small number of highly qualified individuals. If we lose one or more of our key employees, we could suffer a loss of managerial experience, and management resources would have to be diverted from other activities to compensate for this loss. We do not have employment agreements with any of our executive officers. Further, we continue to face a competitive market for hiring and retaining skilled employees. Difficulties in hiring and retaining skilled employees may restrict our ability to adequately support our business needs and/or result in increased personnel costs. There is no assurance that we will be able to attract and retain the personnel necessary to maintain the Company’s strategic direction.
Unfavorable future tax law changes could adversely affect our tax expense. Our income tax positions result in a significant net deferred income tax liability on our consolidated balance sheet. Unfavorable future tax law changes, including increasing U.S. corporate tax rates, could increase this net liability and negatively impact our provision for income taxes and net income.
The impairment of a significant portion of our goodwill and intangible assets would adversely affect our results of operations. Our balance sheet includes goodwill and intangible assets that represent a significant portion of our total assets as of June 30, 2023. On an annual basis, and whenever circumstances require, we review our goodwill and intangible assets for impairment. If the carrying value of a material asset is determined to be impaired, it will be written down to fair value by a charge to operating earnings. An impairment of a significant portion of our goodwill or intangible assets could have a material negative effect on our operating results.
An increase in interest rates could increase our borrowing costs. Although our debt borrowing levels have historically been low, we may require additional or increased borrowings in the future under existing or new debt facilities to support operations, finance acquisitions, or fund stock repurchases. Our current credit facilities bear interest at variable rates. Increases in interest rates on variable-rate debt would increase our interest expense, which could negatively impact our results of operations.
