MW Mamonal plant.
Approximately $77 million of the purchase price was allocated to goodwill and is being amortized over 32 years.
The TermoCandelaria power plant has been included in discontinued operations in the accompanying consolidated financial statements.
The table below presents supplemental unaudited pro forma operating results as if all of the acquisitions had occurred at the beginning of the periods shown (in millions, except per share amounts).
No pro forma operating results are provided for 2001, because the impact would not have been material.
The pro forma amounts include certain adjustments, primarily for depreciation and amortization based on the allocated purchase price and additional interest expense:
## Table 0 ##
The pro forma results are based upon assumptions and estimates that the Company believes are reasonable.
The pro forma results do not purport to be indicative of the results that actually would have been obtained had the acquisitions occurred at the beginning of the periods shown, nor are they intended to be a projection of future results.3.
DISCONTINUED OPERATIONS Effective January 1, 2001, the Company adopted SFAS No.144.
This statement addresses financial accounting and reporting for the impairment or disposal of long-lived assets.
SFAS No.144 requires a component of an entity that either has been disposed of or is classified as held for sale to be reported as discontinued operations if certain conditions are met.
During the year, the Company decided to exit certain of its businesses.
These businesses included Power Direct, Geoutilities, TermoCandelaria, Ib Valley and several telecommunications businesses in Brazil and the U. S.  The businesses were either disposed of or abandoned during the year or were classified as held for sale at December 31, 2001.
For those businesses disposed of or abandoned, the Company determined that significant adverse changes in legal factors and/or the business climate, such as unfavorable market conditions and low tariffs, negatively affected the value of these assets.
The Company has certain businesses that are held for sale, including TermoCandelaria.
The Company has approved and committed to a plan to sell these assets, they are available for immediate sale, and a plan has been established to locate a buyer at a reasonable fair market value price.
The Company believes it will sell these assets within one year and it is unlikely that significant changes will be made to the plan to sell.
At December 31, 2001, the assets and liabilities associated with the discontinued operations are segregated on the consolidated balance sheets.
A majority of the long-lived assets related to discontinued operations are for the TermoCandelaria competitive supply business located in Colombia.
The revenues associated with the discontinued operations were $287 million, $74 million and $7 million for the years ended December 31, 2001, 2000 and 1999, respectively.
The pretax losses associated with the discontinued operations were $58 million, $31 million and $4 million for each of the years ended December 31, 2001, 2000 and 1999, respectively.
The loss on disposal and impairment write-downs for those businesses held for sale, net of tax associated with the discontinued operations, was $145 million for the year ended December 31, 2001.
Owned and leased hotel revenues decreased during the year ended December 31, 2017 compared to the year ended December 31, 2016, as a result of unfavorable foreign currency changes, which decreased revenues by $41 million, offset by an increase in revenues on a currency neutral basis of $39 million.
On a currency neutral basis, owned and leased hotel revenues increased primarily as a result of an increase at our comparable hotels of $41 million due to an increase in RevPAR of 4.8 percent, attributable to increases in ADR and occupancy of 3.2 percent and 1.2 percentage points, respectively.
This increase was partially offset by a decrease in revenues of $5 million due to a net disposal of properties between January 1, 2016 and December 31, 2017.
Owned and leased hotel revenues decreased during the year ended December 31, 2016 compared to the year ended December 31, 2015, primarily as a result of the effect of foreign currency changes and property disposals.
Foreign currency changes accounted for $62 million of the decrease.
On a currency neutral basis, revenues decreased $82 million, which was attributable to a net decrease in revenues of $85 million from properties disposed between January 1, 2015 and December 31, 2016.
Excluding foreign currency changes and property disposals, revenues increased at our comparable owned and leased hotels due to an increase in RevPAR of 2.1 percent, primarily attributable to an increase in ADR of 2.9 percent.
## Table 1 ##
The increases in other revenues during the years ended December 31, 2017 and 2016 compared to the years ended December 31, 2016 and 2015, respectively, were primarily the result of recoveries of $28 million and $9 million, respectively, from the settlement of a claim by Hilton to a third party relating to our defined benefit plans.
OPERATING EXPENSES
## Table 2 ##
Owned and leased hotel expenses decreased during the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily as a result of the effect of foreign currency changes of $40 million.
On a currency neutral basis, owned and leased hotel expenses increased $31 million as a result of an increase of $39 million at our comparable hotels, due to increased variable operating costs driven by increased occupancy.
This increase in owned and leased hotel expenses was partially offset by a decrease at our non-comparable hotels, primarily attributable to a decrease of $10 million in expenses due to a net disposal of properties between January 1, 2016 and December 31, 2017.
Owned and leased hotel expenses decreased during the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily as a result of the effect of foreign currency changes and property disposals.
Foreign currency changes accounted for $65 million of the decrease.
On a currency neutral basis, owned and leased hotel expenses decreased $54 million, primarily as a result of the decrease in expenses of $66 million from properties disposed between January 1, 2015 and December 31, 2016.
## Table 3 ##
The decrease in depreciation and amortization expenses during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily a result of a decrease in amortization expense due to certain capitalized software costs being fully amortized between December 31, 2016 and December 31, 2017.
The decrease in depreciation and amortization expenses during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily a result of the recognition of $13 million in accelerated amortization in 2015 on a management contract intangible asset for a property that was managed by us prior to our acquisition of it and its transfer of ownership to Park upon completion of the spin-offs.
The increase in general and administrative expenses during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily the result of increased share-based compensation expense of $29 million mainly due to an increase in retirement eligible participants, resulting in the acceleration of expense recognition, as well as additional expense recognized from a special equity grant to certain participants in connection with the spin-offs.
Additionally, $18 million in
invested assets was due to increased cash flows from the sales of fixed annuity products and more customers electing the fixed option on variable annuity sales, which were reinvested primarily in fixed maturity securities, other invested assets and mortgage loans.
Yields were adversely impacted by the severe downturn in the global financial markets which primarily impacted real estate joint ventures, fixed maturity securities and cash, cash equivalents and short-term investments.
The moderate improvement in the equity markets in 2009 led to an increase in yields on other limited partnership interests and certain other invested assets, which partially offset the overall reduction in yields.
To manage the needs of our intermediate to longer-term liabilities, our portfolio consists primarily of investment grade corporate fixed maturity securities, structured finance securities, mortgage loans and U. S.  Treasury, agency and government guaranteed fixed maturity securities and, to a lesser extent, certain other invested asset classes, including real estate joint ventures in order to provide additional diversification and opportunity for long-term yield enhancement.
As is typically the case with fixed annuity products, higher net investment income was somewhat offset by higher interest credited expense.
Growth in our fixed annuity policyholder account balances increased interest credited expense by $177 million in 2009 and higher average crediting rates on fixed annuities increased interest credited expense by $37 million.
Operating earnings were negatively impacted by $348 million of operating losses related to the hedging programs for variable annuity minimum death and income benefit guarantees, which are not embedded derivatives, partially offset by a decrease in the liability established for these variable annuity guarantees.
The various hedging strategies in place to offset the risk associated with these variable annuity guarantee benefits were more sensitive to market movements than the liability for the guaranteed benefit.
Market volatility, improvements in the equity markets, and higher interest rates produced operating losses on these hedging strategies in the current year.
Our hedging strategies, which are a key part of our risk management, performed as anticipated.
The decrease in annuity guarantee benefit liabilities was due to the improvement in the equity markets, higher interest rates and the annual unlocking of future market expectations.
Other expenses increased by $221 million primarily due to an increase of $122 million from the impact of market conditions on certain expenses.
These expenses are largely comprised of reinsurance costs, pension and postretirement benefit expenses, and letter of credit fees.
In addition, variable expenses, such as commissions and premium taxes, increased $76 million, the majority of which have been offset by DAC capitalization.
The positive impact of our Operational Excellence initiative was reflected in lower information technology, travel, professional services and advertising expenses, but was more than offset by increases largely due to business growth.
Finally, policy fees and other revenues decreased by $100 million, mainly due to lower average separate account balances in the current year versus prior year.
Corporate Benefit Funding
## Table 4 ##
Corporate Benefit Funding benefited in certain markets in 2009 as a flight to quality helped drive our increase in market share, especially in the structured settlement business, where we experienced a 53% increase in premiums.
Our pension closeout business in the United Kingdom continues to expand and experienced premium growth during 2009 of almost $400 million, or 105% before income taxes.
However, this growth was more than offset by a decline in our domestic pension closeout business driven by unfavorable market conditions and regulatory changes.
A combination of poor equity returns and lower interest rates have contributed to pension plans being under funded, which reduces our customers’ flexibility to engage in transactions such as pension closeouts.
Our customers’ plans funded status may be affected by a variety of factors, including the ongoing phased implementation of the Pensions Protection Act of 2006.
For each of these businesses, the movement in premiums is almost entirely offset by the related change in policyholder benefits.
The insurance liability that is established at the time we assume the risk under these contracts is typically equivalent to the premium earned.
Market conditions also contributed to a lower demand for several of our investment-type products.
The decrease in sales of these investment-type products is not necessarily evident in our results of operations as the transactions related to these products are recorded through the balance sheet.
Our funding agreement products, primarily the London Inter-Bank Offer Rate (“LIBOR”) based contracts, experienced the most significant impact from the volatile market conditions.
As companies seek greater liquidity, investment managers are refraining from repurchasing the contracts when they mature and are opting for more liquid investments.
In addition, unfavorable market conditions continued to impact the demand for global guaranteed interest contracts, a type of funding agreement.
