We reclassified certain accrued expenses to accounts payable trade accounts for the prior period to conform to the current year presentation. These reclassifications had no impact on the financial statements.

The increase in the long-term portion of the asset retirement obligation from $124 million at December 31, 2019 to $138 million at June 30, 2020 was due to $5 million of accretion, $6 million of liabilities incurred and

reclassification of $12 million from the current to long-term portion due to changes in anticipated spending and regulatory requirements. These increases were partially offset by $9 million of liabilities settled during the period.

Other non-current liabilities at June 30, 2020 and December 31, 2019 included approximately $31 million and $33 million of greenhouse gas liability, respectively.

Cash and cash equivalents consist primarily of highly liquid investments with original maturities of three months or less and are stated at cost, which approximates fair value. As part of our cash management system, we use a controlled disbursement account to fund cash distribution checks presented for payment by the holder. Checks issued but not yet presented to banks may result in overdraft balances, which amounts are immaterial for these periods, for accounting purposes in the accounts payable and accrued expenses account.
