Please answer the given financial question based on the context.
Context: ireland . holdings ireland , everest dublin holdings , ireland re and ireland insurance conduct business in ireland and are subject to taxation in ireland . aavailable information . the company 2019s annual reports on form 10-k , quarterly reports on form 10-q , current reports on form 8-k , proxy statements and amendments to those reports are available free of charge through the company 2019s internet website at http://www.everestre.com as soon as reasonably practicable after such reports are electronically filed with the securities and exchange commission ( the 201csec 201d ) . item 1a . risk factors in addition to the other information provided in this report , the following risk factors should be considered when evaluating an investment in our securities . if the circumstances contemplated by the individual risk factors materialize , our business , financial condition and results of operations could be materially and adversely affected and the trading price of our common shares could decline significantly . risks relating to our business fluctuations in the financial markets could result in investment losses . prolonged and severe disruptions in the overall public and private debt and equity markets , such as occurred during 2008 , could result in significant realized and unrealized losses in our investment portfolio . although financial markets have significantly improved since 2008 , they could deteriorate in the future . there could also be disruption in individual market sectors , such as occurred in the energy sector in recent years . such declines in the financial markets could result in significant realized and unrealized losses on investments and could have a material adverse impact on our results of operations , equity , business and insurer financial strength and debt ratings . our results could be adversely affected by catastrophic events . we are exposed to unpredictable catastrophic events , including weather-related and other natural catastrophes , as well as acts of terrorism . any material reduction in our operating results caused by the occurrence of one or more catastrophes could inhibit our ability to pay dividends or to meet our interest and principal payment obligations . by way of illustration , during the past five calendar years , pre-tax catastrophe losses , net of reinsurance , were as follows: .
|calendar year:|pre-tax catastrophe losses|
|( dollars in millions )||
|2018|$ 1800.2|
|2017|1472.6|
|2016|301.2|
|2015|53.8|
|2014|56.3|
our losses from future catastrophic events could exceed our projections . we use projections of possible losses from future catastrophic events of varying types and magnitudes as a strategic underwriting tool . we use these loss projections to estimate our potential catastrophe losses in certain geographic areas and decide on the placement of retrocessional coverage or other actions to limit the extent of potential losses in a given geographic area . these loss projections are approximations , reliant on a mix of quantitative and qualitative processes , and actual losses may exceed the projections by a material amount , resulting in a material adverse effect on our financial condition and results of operations. .
