The improvement in admissions spending per capita for the first six months of 2020 was primarily due to recurring monthly membership revenue in the first quarter of 2020 from members who retained their memberships on a monthly basis after their initial 12-month commitment period ended. Prior to the suspension of park operations, when the company began deferring this revenue while park operations were suspended, these payments were recognized as received. Higher guest spending per capita by single-day guests prior to the suspension of operations also contributed to the improvement. The decrease in in-park spending per capita was driven by attendance at the company’s drive-through Safari, which lacks in-park spending opportunities.
Active Pass Base
The company is working with its members and season pass holders to extend their usage privileges to compensate for any lost days due to its temporary park closures, and is offering higher-tiered benefits to members in return for maintaining their current payment schedule. The company has also offered members the option to pause payments on their current membership. However, as anticipated, the company sold fewer season passes and memberships while its parks were not operating compared to the same period in 2019. As a result, the Active Pass Base decreased 38 percent as of the end of the second quarter of 2020 compared to the same prior year period. Included in the Active Pass Base were 2.1 million members, compared to 2.6 million members at the end of 2019 and 2.4 million members at the end of the first quarter of 2020.
Deferred revenue was $182 million as of June 30, 2020, a decrease of $53 million, or 22 percent, from June 30, 2019. The decrease in deferred revenue was primarily due to lower season pass and membership sales. This was partially offset by the deferral of revenue from members and season pass holders.
For those members whose initial 12-month commitment period ended, but who continued paying for membership on a monthly basis after the parks temporarily closed for the pandemic, revenue will be deferred until the end of their membership. In contrast, payments from members whose initial 12-month commitment period had ended in 2019 were recognized as they were received and had limited contribution to deferred revenue in the prior year period.
Balance Sheet and Liquidity
As of June 30, 2020, the company had cash on hand of $296 million and $460 million available under its revolving credit facility, net of $21 million of letters of credit, or total liquidity of $756 million. Based on the parks that are currently open, the company estimates that its net cash outflow2 through the end of 2020 will be, on average, $25-$30 million per month. The company has no debt maturities until 2024.
In the first half of 2020, the company invested $73 million in new capital projects, net of property insurance recoveries, paid $21 million in dividends, and prepaid $51 million of its 4.875 percent notes due 2024. Net debt as of June 30, 2020, calculated as total reported debt of $2,620 million less cash and cash equivalents of $296 million, was $2,324 million.
In April, the company amended its credit facility to, among other things, suspend testing of its senior secured leverage ratio financial maintenance covenant through December 31, 2020. The company’s lenders also approved modified testing of the senior secured leverage ratio financial maintenance covenant through December 31, 2021. Through the duration of the amendment period ending December 31, 2021, the company agreed to suspend paying dividends and repurchasing its common stock, and to maintain minimum liquidity of $150 million.
In response to curtailed operations, and to preserve the company’s liquidity position and prepare for multiple contingencies, the company continues to take actions to reduce operating expenses and defer or eliminate certain discretionary capital projects planned for 2020 and 2021. The company is able to take additional measures or further modify park operations and park schedules based on changing conditions.
At this time, the company anticipates it has sufficient liquidity to meet its cash obligations through the end of 2021 even if the currently open parks are forced to close; however, if its operations continue to be
