profits from some of our subsidiaries in 2021 and a VND77.0 billion increase in deferred income tax expense primarily attributable to a VND143.6 billion increase from investment gains from changes in the price of common stock of Vinhomes and Vingroup. This increase was partially offset by a VND57.2 billion decrease from a realization of deferred tax liabilities arising in 2020 from a fair value gain on cross-currency interest rate swap contracts.
Net loss for the year
For the reasons described above, our net loss for the year increased by VND13,268.7 billion, or 70.0%, to VND32,219.0 billion for the year ended December 31, 2021 compared to VND18,950.2 billion for the year ended December 31, 2020.
Liquidity and Capital Resources
We have had negative net cash flows from operating activities and expect our cash flows to remain negative at least for the near term as we scale and ramp up production and sales of our vehicles, establish our manufacturing operations and expand our marketing, sales and service network in our target markets outside of Vietnam. Since our inception, we have financed our operations primarily though debt and equity financing activities, including support from our parent company, Vingroup, for borrowings, corporate loan guarantees, and capital contribution.
We had net losses of VND18,950.2 billion, VND32,219.0 billion and VND49,848.9 billion ($2,111.2 million) in 2020, 2021 and 2022 respectively. We had net cash flows used in operating activities of VND9,349.2 billion, VND28,969.1 billion and VND35,628.4 billion ($1,508.9 million) in 2020, 2021 and 2022, respectively. We expect to continue to incur operating and net losses in the near term as we scale the production of our VF e34 (C-segment), VF 5 (A-segment), VF 6 (B-segment), VF 7 (C-segment), VF 8 (D-segment) and VF 9 (E-segment) vehicles, establish our manufacturing operations and expand our marketing, sales and service network in our target markets outside of Vietnam. In addition, we had total current liabilities of VND66,225.2 billion ($2,804.7 million) and accumulated losses of VND127,188.5 billion ($5,386.6 million) as of December 31, 2022.
As of December 31, 2022, we had cash and cash equivalents of VND4,271.4 billion ($180.9 million). We hold and maintain cash and cash equivalents taking into account our current business plans, expected monthly cash flows from operations and expected monthly cash outlays on a monthly basis.
As of December 31, 2022, we had VND2,406.7 billion ($101.9 million) of undrawn lines of credit for short-term financing under our existing credit facilities, and VND4,271.4 billion ($180.9 million) in cash and cash equivalents, of which 3.6% was held in Vietnamese Dong and the remaining 96.4% were held in foreign currencies, such as U.S. dollars, Euros, Australian dollars, Canadian dollars and Singapore dollars. Our primary requirements for liquidity are to finance working capital, capital expenditures and general corporate purposes. See “Description of Certain Indebtedness.”
Our capital expenditures (which are our purchases of property, plant and equipment and intangible assets) paid during the years ended December 31, 2020, 2021 and 2022 were VND9,672.2 billion, VND6,007.9 billion and VND17,681.7 billion ($748.8 million), respectively. In 2020, our capital expenditures primarily consisted of purchases of property, plant and equipment and intangible assets, such as the Lang Proving Ground (Australia), supplier park and machineries and equipment for ICE projects. In 2021, our capital expenditures primarily comprised the purchase of machineries and equipment for our EV projects and the supplier park in our Hai Phong facility. In 2022, our capital expenditures primarily consisted of purchases of machineries and equipment for our EV projects, construction of showrooms and charging stations at target markets and construction of the factory in the U.S. As of December 31, 2022, we had committed capital expenditures of VND12,618.2 billion ($534.4 million), which was primarily related to the purchase and installation of machinery and equipment, information technology systems and deployment of site clearance and construction of factories, showrooms and charging stations.
