Operating Activities Operating activities provided $2.5 million of net cash in 2023 and provided $8.9 million of net cash in 2022, a decrease in net cash provided by operating activities of $6.4 million.
Income tax benefit for 2021 was $0.1 million and related to losses generated in foreign jurisdictions. There was no associated tax benefit related to losses incurred in the U.S. due to a full valuation allowance on our related deferred tax assets. The effective tax rate for 2022 was (16.2)% on continued operations.
Income Tax Expense Income tax expense for 2023 and 2022 was $0.3 million and $0.5 million, respectively, and related to taxes on income earned in foreign jurisdictions. The effective tax rate from continuing operations for 2023 and 2022 was (2.1)% and (15.8)%, respectively.
The $6.0 million increase is primarily due to a $33.9 million increase in net income, an increase in cash inflows of $6.1 million related to accounts payable and accrued expenses, an increase in cash inflows of $1.2 million related to other non-current assets and non-current contract assets, an increase in cash inflows of $1.0 million related to accounts receivable, and a decrease in cash outflows of $0.1 million related to contract liabilities and long-term contract liabilities.
Partially offsetting these items were a change of $37.9 million related to non-cash items, driven by the $30.8 million gain on sale of the inertial navigation business in 2022 and the $6.0 million impairment of goodwill and long-lived assets, a $12.2 million decrease in cash outflows relating to inventories, a $8.4 million decrease in cash outflows relating to accrued compensation, product warranty and other expenses, a $1.2 million increase in cash inflows relating to accounts receivable, and a $0.8 million increase in cash inflows related to deferred revenue.
The $1.9 million decrease in net cash provided by financing activities is primarily attributable to the $2.0 million decrease in cash inflows relating to proceeds from stock options exercises and the employee stock purchase plan.
The $1.6 million increase in net cash provided by financing activities is primarily attributable to a $1.6 million increase in cash inflows relating to proceeds from the exercise of stock options and purchases under our employee stock purchase plan and a $0.2 million decrease in cash outflows related to the payment of finance leases, partially offset by a $0.2 million increase in cash outflows related to the repurchase of common stock to satisfy specific tax withholding obligations arising from accelerated vesting of executive stock grants. 33 Table of Contents Other Matters We intend to continue to invest in our global HTS network on a worldwide basis.
