We manage our credit risk exposure through assessment of our counterparty creditworthiness. Cash equivalents consist primarily of time deposits, and money market funds. We place our cash and cash equivalents in what we believe to be credit-worthy financial institutions. Our money market funds are carried at fair market value. Voyage receivables consist of (i) operating lease receivables associated with revenues from leases accounted for under ASC 842, <i style="font-style:italic;">Leases </i>(ASC 842), which are primarily unbilled amounts due from pools; and (ii) billed and unbilled non-operating lease receivables associated with revenues from services accounted for under ASC 606, <i style="font-style:italic;">Revenue from Contracts with Customers</i> (ASC 606), which are due within one year. We perform ongoing evaluations to determine customer credit and we limit the amount of credit we extend. We maintain allowances for estimated credit losses and these losses have generally been within our expectations. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;padding-left:18pt;text-indent:-18pt;margin:0pt;"><span style="background-color:#ffff00;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 0pt 18pt;">With respect to non-operating lease receivables, the Company recognizes as an allowance its estimate of expected credit losses in accordance with ASC 326, <i style="font-style:italic;">Financial Instruments – Credit losses</i> (ASC 326), based on troubled accounts, historical experience, other currently available evidence, and reasonable and supportable forecasts about the future. The Company makes significant judgements and assumptions to estimate its expected losses. We make judgments about the creditworthiness of customers based on ongoing credit evaluations including analysis of the counterparty’s established credit rating or assessment of the counterparty’s creditworthiness based on our analysis of their financial statements when a credit rating is not available, country and political risk </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 0pt 18pt;">of the counterparty, and their business strategy. We manage our non-operating lease receivable portfolios using delinquency as a key credit quality indicator. The Company performs the following steps in estimating expected losses: (i) gather historical losses over 5 years; (ii) assume outstanding billed amounts over 180 days as additional expected losses; and (iii) make forward-looking adjustments to the expected losses to reflect future economic conditions by comparing credit default swap rates of significant customers over time. In addition, the Company performs individual assessments for customers that do not share risk characteristics with other customers (for example a customer under bankruptcy or a customer with known disputes or collectability issues).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 0pt 18pt;"><span style="margin-left:0pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 0pt 18pt;">The allowance for credit losses is recognized as an allowance or contra-asset and reflects our best estimate of probable losses inherent in the voyage receivables balance. Provisions for credit losses associated with voyage receivables are included in provision for credit losses on the consolidated statements of operations. Activity for allowance for credit losses is summarized as follows:</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 0pt 18pt;"><span

The most significant estimates relate to the depreciation of vessels and other property, amortization of drydocking costs, judgments involved in identifying performance obligations in revenue contracts, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each performance obligation, estimates used in assessing the recoverability of equity method investments and other long-lived assets, liabilities incurred relating to pension benefits, and income taxes. Actual results could differ from those estimates.</p>
