Depreciation of property and equipment was $281 million, $297 million and $262 million during the years ended December 31, 2021, 2020 and 2019, respectively.

For the year ended December 31, 2021, we recognized $5 million of impairment losses related to one of our hotels, which was classified as held for sale as of June 30, 2021, and subsequently sold in July 2021, as the estimated selling costs were expected to reduce the gross proceeds below the net book value of the property.

For the year ended December 31, 2020, we recognized $90 million of impairment losses, primarily related to one of our hotels, and our inability to recover the carrying value of the asset because of COVID-19.

In October 2016, we completed the sale of 600 rooms at the Hilton Waikoloa Village to HGV in connection with timeshare projects. The net book value of these assets was approximately $177 million. Due to our continuing involvement, this transaction was not recognized as a sale and was accounted for as a sales-leaseback liability under the financing method. Pursuant to an arrangement representing a lease, we reserved exclusive rights to occupy and operate these rooms beginning on the date of transfer and continuing until the end of the lease term, which expired on December 31, 2019. During 2017, 134 of the 600 rooms at the Hilton Waikoloa Village previously transferred to HGV and leased back by us were released to HGV; accordingly, we derecognized $38 million of property and equipment, net, and the related $39 million liability due to HGV. During 2018, we transferred a restaurant at the Hilton Waikoloa Village to HGV and derecognized $3 million of property and equipment, net and $3 million of the related liability due to HGV. On December 31, 2019, the remaining 466 rooms at the Hilton Waikoloa Village were released to HGV and we derecognized $123 million of property and equipment, net, and the related $135 million liability due to HGV, and recognized a gain of $12 million within other (loss) gain, net in our consolidated statements of comprehensive (loss) income.

In September 2017, Hurricanes Irma and Maria caused damage and disruption at certain of our hotels in Florida and the Caribe Hilton in Puerto Rico. The Caribe Hilton remained closed throughout 2018 and reopened on May 15, 2019. Our insurance coverage provides us with reimbursement for the replacement cost for the damage to these hotels, which includes certain clean-up and repair costs, exceeding the applicable deductibles, in addition to loss of business. Claims related to the Hilton Caribe were fully settled in December 2019, and claims related to our Florida hotels were fully settled in January 2021.

During the year ended December 31, 2019, we recognized $70 million of insurance recoveries, of which $39 million related to property damage, $28 million related to business interruption, and $3 million related to expense reimbursements. Business interruption proceeds are included within ancillary hotel revenue in our consolidated statements of comprehensive (loss) income. Additionally, we recognized a net gain of $18 million within impairment and casualty loss, net in our consolidated statements of comprehensive (loss) income, which includes a gain of $27 million for amounts recovered from insurance in excess of the insurance receivable and a loss of $9 million relating to property damage at certain of our hotels that we may not recover from insurers.
