The changes in our net operating assets and liabilities were primarily due to a $7.5 million increase in accounts receivable, an increase in other assets of $2.7 million, and an increase in non-trade receivable of $1.8 million, partially offset by a $4.2 million decrease in inventory, a $1.6 million decrease in prepaid expenses, and a $1.2 million increase in accounts payables and accrued liabilities.
The changes in our net operating assets and liabilities were primarily due to an increase in contract fulfillment assets of $4.5 from the capitalization of certification costs, an increase of $3.0 million in accounts receivable due to the timing of sales at year-end, and an increase of $2.6 million in inventory due to the timing of shipments at year-end.
As a result of the foregoing, substantial doubt exists regarding our ability to continue as a going concern for a period of at least one year from the date of issuance of the audited consolidated financial statements included in this Annual Report on Form 10-K. 45 To mitigate the risks noted above, our management is currently evaluating various funding alternatives and may seek to raise additional funds through the issuance of equity, mezzanine or debt securities, through arrangements with strategic or investment partners with greater resources or access to funds, or through obtaining credit from government or financial institutions.

We sell our mobile phones and accessories primarily to wireless carriers in both the United States and Canada, who then resell our products in conjunction with network services to end customers. We sell our tablets to a customer that rebrands them, and sells to customers in the U.S.
These carriers then resell our products, along with network services, to end customers focusing on two primary end markets: industrial enterprise and public sector. In 2023 and 2022, tablets were sold to a customer who resold them to a carrier in the U.S.
Because our U.S. sales channel is primarily comprised of large wireless carriers, the number of customers that we sell to is limited. For the year ended December 31, 2022, 53% of our revenues came from large wireless carriers and 41% came from our top three carrier customers. Our tablet customer accounts for 42% of our revenue.
