technology, human resources and other systems and infrastructure, and also include transitioning the project-level O&M and asset management services in-house or to third party service providers. While these efforts are largely complete, they involve a number of new risks and challenges that may materially adversely affect our business, results of operations and financial condition.
Finalizing these changes may take longer than we expect, cost more than we expect, and divert management’s attention from other aspects of our business. We may also incur substantial legal and compliance costs in many of the jurisdictions where we operate.
If we are deemed to be an investment company, we may be required to institute burdensome compliance requirements and our activities may be restricted, which may make it difficult for us to complete strategic acquisitions or affect combinations.
If we are deemed to be an investment company under the Investment Company Act of 1940 (the “Investment Company Act”) our business would be subject to applicable restrictions under the Investment Company Act, which could make it impractical for us to continue our business as contemplated. We believe our company is not an investment company under Section 3(b)(1) of the Investment Company Act because we are primarily engaged in a non-investment company business, and we intend to conduct our operations so that we will not be deemed an investment company. However, if we were to be deemed an investment company, restrictions imposed by the Investment Company Act, including limitations on our capital structure and our ability to transact with affiliates, could make it impractical for us to continue our business as contemplated.
Potential future delays in the filing of our reports with the SEC, as well as further delays in the preparation of audited financial statements at the project level, could have a material adverse effect.
We did not file with the SEC on a timely basis our Annual Reports on Form 10-K for each of the years ended December 31, 2015 and 2016 and our Quarterly Reports on Form 10-Q for each of the quarters ended March 31, 2016, June 30, 2016, September 30, 2016, March 31, 2017, June 30, 2017 and March 31, 2018. We filed our Annual Reports on Form 10-K for the year ended December 31, 2017 and 2018, and our Quarterly Reports on Form 10-Q for each of the quarters ended September 30, 2017 and June 30, 2018 after the applicable filing deadline but within the applicable grace period provided by the SEC. During the period of these delays, we received notification letters from Nasdaq that granted extensions to regain compliance with Nasdaq’s continued listing requirements, subject to the requirement that we file our SEC reports and hold our annual meeting of stockholders by certain deadlines. While we are now current in our filing of periodic reports under the Exchange Act, and are in compliance with Nasdaq's continued listing requirements, in the event that any future periodic report is delayed, there is no assurance that we will be able to obtain further extensions from Nasdaq to maintain or regain compliance with Nasdaq’s continued listing requirements with respect to any such delayed periodic report. If we fail to obtain any such further extensions from Nasdaq, our Class A common stock would likely be delisted from the Nasdaq Global Select Market.
The delay in filing our Annual Reports on Form 10-K and our Quarterly Reports on Form 10-Q and related financial statements has at times impaired our ability to obtain financing and access the capital markets, and to the extent we fail to make timely filings in the future, our access to financing may be impaired. For example, as a result of the delayed filing of our periodic reports with the SEC, we will not be eligible to register the offer and sale of our securities using a short-form registration statement on Form S-3 until we have timely filed all periodic reports required under the Exchange Act for one year. Additional delays may also negatively impact our ability to obtain project financing and our ability to obtain waivers or forbearances to the extent of any defaults or breaches of project-level financing. An inability to obtaining financing may have a material adverse effect on our ability to grow our business, acquire assets through acquisitions or optimize our portfolio and capital structure. Additionally, a delay in audited financial statements may make our Board less comfortable with approving the payment of dividends.
Financial statements at the project-level have also been delayed over the course of 2016, 2017 and 2018. This delay created defaults under most of our non-recourse financing agreements, which have been substantially cured or waived as of the date hereof. To the extent any remaining defaults remain uncured or unwaived, or new defaults arise because of future delays in the completion of audited or unaudited financial statements, our subsidiaries may be restricted in their the ability to make distributions to us, or the related lenders may be entitled to demand repayment or enforce their security interests, which could have a material adverse effect on our business, results of operations, financial condition, our ability to pay dividends and our ability to comply with corporate-level debt covenants.
Our future tax liability may be greater than expected if we do not generate NOLs sufficient to offset taxable income or if tax authorities challenge certain of our tax positions.
