The existence of these or other material weakness in our internal control over financial reporting could also result in errors in our financial statements that could require us to restate our financial statements, cause us to fail to meet our reporting obligations and cause stockholders to lose confidence in our reported financial information, all of which could materially and adversely affect our business and stock price.
We are involved in costly and time-consuming litigation and other regulatory proceedings which require significant attention from our management, which involve a greater exposure to legal liability and may result in significant damage awards and which may relate to the operations of our renewable energy facilities.
We have been and continue to be involved in legal proceedings, administrative proceedings, claims and other litigation that arise in the ordinary course of business, including proceedings related to the operation of our renewable energy facilities. For example, individuals or groups have in the past and may in the future challenge the issuance of a permit for a renewable energy facility or may make claims related to alleged impacts of the operation of our renewable energy facilities on adjacent properties. In addition, we are named as defendants from time to time in other lawsuits and regulatory actions relating to our business, some of which may claim significant damages. We have also been subject to claims arising out of our acquisition activities with respect to certain payments in connection with the acquisition of First Wind by SunEdison.
Due to the inherent uncertainties of litigation and regulatory proceedings, we cannot accurately predict the ultimate outcome of any such proceedings. Unfavorable outcomes or developments relating to these proceedings, or new proceedings involving similar allegations or otherwise, such as monetary damages or equitable remedies, could have a material adverse impact on our business and financial position, results of operations or cash flows or limit our ability to engage in certain of our business activities. Settlement of claims could adversely affect our financial condition, results of operations and cash flows. In addition, regardless of the outcome of any litigation or regulatory proceedings, such proceedings are often expensive, lengthy and disruptive to normal business operations and require significant attention from our management. We are currently and/or may be subject in the future to claims, lawsuits or arbitration proceedings related to matters in tort or under contracts, employment matters, securities class action lawsuits, shareholder derivative actions, breaches of fiduciary duty, conflicts of interest, tax authority examinations or other lawsuits, regulatory actions or government inquiries and investigations.
In the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We have been the target of such securities litigation in the past (see Note 19. Commitments and Contingencies to our consolidated financial statements, included in this Annual Report on Form 10-K) and we may become the target of additional securities litigation in the future, which could result in substantial costs and divert our management’s attention from other business concerns, which could have a material adverse effect on our business.
The settlement of certain existing litigation will trigger a requirement to issue additional Class A common stock to Brookfield.
We have agreed, in the Merger Agreement, to issue additional shares of Class A common stock to Brookfield for no additional consideration in respect of the final resolution of certain specified litigation (see Note 19. Commitments and Contingencies to our consolidated financial statements for a description of such litigation). The number of additional shares of Class A common stock to be issued to Brookfield is subject to a pre-determined formula as set forth in the Merger Agreement as described in greater detail in the Company's Definitive Proxy Statement filed on Schedule 14A with the SEC on September 6, 2017 and will compensate Brookfield for the total amount of losses we incur with respect to such specified litigation. The number of shares of Class A common stock to be issued to Brookfield could be significant, resulting in the dilution of the ownership interests of our remaining Class A common stockholders.
A significant portion of our assets consists of long-lived assets, the value of which may be reduced if we determine that those assets are impaired.
As of December 31, 2017, the net carrying value of long-lived assets represented $5,879.7 million, or 92%, of our total assets and consisted of renewable energy facilities and intangible assets. Renewable energy facilities and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate carrying values may not be recoverable. An impairment loss is recognized if the total future estimated undiscounted cash flows expected from an asset are less than its carrying value.
As a result of classifying substantially all of our portfolio of residential rooftop solar assets located in the United States as held for sale during the fourth quarter of 2016 and determining that the carrying value exceeded the fair value less
