Section 158.49 - Handling of PFC's(a) Collecting carriers shall establish and maintain a financial management system to account for PFC's in accordance with the Department of Transportation's Uniform System of Accounts and Reports ( 14 CFR part 241 ). For carriers not subject to 14 CFR part 241 , such carriers shall establish and maintain an accounts payable system to handle PFC revenue with subaccounts for each public agency to which such carrier remits PFC revenue.(b) Collecting carriers must account for PFC revenue separately. PFC revenue may be commingled with the air carrier's other sources of revenue except for covered air carriers discussed in paragraph (c) of this section. PFC revenues held by an air carrier or an agent of the air carrier after collection are held in trust for the beneficial interest of the public agency imposing the PFC. Such air carrier or agent holds neither legal nor equitable interest in the PFC revenues except for any handling fee or interest collected on unremitted proceeds as authorized in § 158.53 .(c)(1) A covered air carrier must segregate PFC revenue in a designated separate PFC account. Regardless of the amount of PFC revenue in the covered air carrier's account at the time the bankruptcy petition is filed, the covered air carrier must deposit into the separate PFC account an amount equal to the average monthly liability for PFCs collected under this section by such air carrier or any of its agents. (i) The covered air carrier is required to create one PFC account to cover all PFC revenue it collects. The designated PFC account is solely for PFC transactions and the covered air carrier must make all PFC transactions from that PFC account. The covered air carrier is not required to create separate PFC accounts for each airport where a PFC is imposed.(ii) The covered air carrier must transfer PFCs from its general accounts into the separate PFC account in an amount equal to the average monthly liability for PFCs as the "PFC reserve." The PFC reserve must equal a one-month average of the sum of the total PFCs collected by the covered air carrier, net of any credits or handling fees allowed by law, during the past 12-month period of PFC collections immediately before entering bankruptcy.(iii) The minimum PFC reserve balance must never fall below the fixed amount defined in paragraph (c)(1)(ii) of this section.(iv) A covered air carrier may continue to deposit the PFCs it collects into its general operating accounts combined with ticket sales revenue. However, at least once every business day, the covered air carrier must remove all PFC revenue (Daily PFC amount) from those accounts and transfer it to the new PFC account. An estimate based on 1/30 of the PFC reserve balance is permitted in substitution of the Daily PFC amount. (A) In the event a covered air carrier ceases operations while still owing PFC remittances, the PFC reserve fund may be used to make those remittances. If there is any balance in the PFC reserve fund after all PFC remittances are made, that balance will be returned to the covered air carrier's general account.(B) In the event a covered air carrier emerges from bankruptcy protection and ceases to be a covered air carrier, any balance remaining in the PFC reserve fund after any outstanding PFC obligations are met will be returned to the air carrier's general account.(v) If the covered air carrier uses an estimate rather than the daily PFC amount, the covered air carrier shall reconcile the estimated amount with the actual amount of PFCs collected for the prior month (Actual Monthly PFCs). This reconciliation must take place no later than the 20th day of the month (or the next business day if the date is not a business day). In the event the Actual Monthly PFCs are greater than the aggregate estimated PFC amount, the covered air carrier will, within one business day of the reconciliation, deposit the difference into the PFC account. If the Actual Monthly PFCs are less than the aggregate estimated PFC amount, the covered air carrier will be entitled to a credit in the amount of the difference to be applied to the daily PFC amount due.(vi) The covered air carrier is permitted to recalculate and reset the PFC reserve and daily PFC amount on each successive anniversary date of its bankruptcy petition using the methodology described above.(2) If a covered air carrier or its agent fails to segregate PFC revenue in violation of paragraph (c)(1) of this section, the trust fund status of such revenue shall not be defeated by an inability of any party to identify and trace the precise funds in the accounts of the air carrier.(3) A covered air carrier and its agents may not grant to any third party any security or other interest in PFC revenue.(4) A covered air carrier that fails to comply with any requirement of paragraph (c) of this section, or causes an eligible public agency to spend funds to recover or retain payment of PFC revenue, must compensate that public agency for those cost incurred to recover the PFCs owed.(5) The provisions of paragraph (b) of this section that allow the commingling of PFCs with other air carrier revenue do not apply to a covered air carrier.(d) All collecting air carriers must disclose the existence and amount of PFC funds regarded as trust funds in their financial statements.Doc.
