Contract Balances
Substantially all the Company's receivables relate to contracts with customers. Accounts receivable are recorded when the right to consideration becomes unconditional. Payment terms on invoices range from 30 to 120 days depending on the customary business practices of the jurisdictions in which we do business.
    Certain short-term and longer-term sales contracts require up-front payments prior to the Company’s fulfillment of any performance obligation. These contract liabilities are recorded as current or long-term deferred revenue, depending on the lag between the prepayment and the expected delivery of the related products. Additionally, deferred revenue or contract assets originate from contracts where the allocation of the transaction price to the performance obligations based on their relative stand-alone selling prices results in the timing of revenue recognition being different from the timing of the invoicing. In this case, deferred revenue is amortized into revenue based on the transaction price allocated to the remaining performance obligations and contract assets are realized through the contract invoicing.
    The Company did not have any contract asset balances as of December 31, 2022. Contract assets as of December 31, 2021 were $1.2 million, which are included in "Prepaid expenses and other current assets" on the Consolidated Balance Sheets.
Current deferred revenue is included in "Other accrued liabilities" and long-term deferred revenue is included in "Other long-term obligations" on the Consolidated Balance Sheets. The following table provides our contract liability balances as of December 31, 2022 and 2021.
December 31, 2022December 31, 2021
(Dollars in thousands)
Current deferred revenue$27,878 $9,840 
Long-term deferred revenue— 4,303 
The amount of revenue recognized in 2022 that was included in the December 31, 2021 deferred revenue current and long-term balances was $2.5 million and $0.1 million, respectively. The increase in the December 31, 2022 current deferred revenue balance versus the prior year was primarily driven by shipments relative to some contractual prepayments being postponed to the following year. Additionally, the balance includes cashed bank guarantees relative to outstanding arbitration proceedings whose outcome will determine timing of revenue recognition. The amount of revenue recognized in 2021 that was included in the December 31, 2020 deferred revenue current balance was $5.5 million.
Transaction Price Allocated to the Remaining Performance Obligations
The following table presents estimated revenues expected to be recognized in the corresponding period below related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of reporting period. The revenue associated with our LTAs is expected to be approximately as follows:

(Dollars in millions)
Estimated LTA revenue
$235-$275
$100-$135(1)
(1) Includes expected termination fees from a few customers that have failed to meet certain obligations under their LTAs.
The majority of the LTAs are defined as pre-determined fixed annual volume contracts while a small portion are defined with a specified volume range. For the years 2023 and 2024, the contractual revenue amounts above are based upon the minimum volume for those contracts with specified ranges. The actual revenue realized from these contracted volumes may vary in timing and total due to contract non-performance, force majeure notices, arbitrations, credit risk associated with certain customers facing financial challenges and customer demand related to contracted volume ranges. As it relates to the conflict between Ukraine and Russia, we have provided force majeure notices with respect to certain impacted LTAs. In the event of a force majeure, the LTAs provide our counterparties with the right to terminate the LTA if the force majeure event continues for more than six months after the delivery of the force majeure notice, with no continuing obligations of either party. Certain of our LTA counterparties have challenged the force majeure notices, but we will continue to enforce our contractual rights, while other LTAs have been terminated as a result of the force majeure period elapsing. The estimates of LTA revenue as set forth above in the immediately preceding table includes (i) our current view of the validity of such force majeure notices and (ii) our current expectations of termination fees from our customers who have failed to meet certain obligations under their LTAs.
