The regulatory environment related to information security, data collection and use, and privacy is increasingly rigorous, with new and frequently changing requirements, and compliance with those requirements could result in additional costs. These costs associated with information security, such as increased investment in technology, the costs of compliance with privacy laws, and costs incurred to prevent or remediate information security breaches, could be substantial and adversely affect our business. A significant compromise of sensitive employee, Distribution Partner, client or supplier data in our possession could result in legal damages and regulatory penalties. In addition, the costs of defending such actions or remediating breaches could be material.
Damage to our information technology and software systems could impair our ability to effectively provide DIRTT Solutions, harm our reputation, and adversely affect our business.
Our information technology and software networks and systems, which include the processing, transmission and storage of information, are integrated with our manufacturing processes and essential to our business operations. These systems are vulnerable to, among other things, damage or interruption from power outages, network failures or natural disasters, loss or corruption of data, human error, employee misconduct and difficulties associated with upgrades, installations of major software or hardware, and integration with new systems. While we maintain retention backupsto geo-diverse digital and physical locations and have a recovery data center, the data center and other protective measures we take could prove to be inadequate. Any disruption in our systems or unauthorized disclosure of information could result in delayed manufacturing and delivery of our DIRTT Solutions, legal claims, a loss of intellectual property and a disruption in operations, all of which could adversely affect our reputation, relationships with clients, financial condition and results of operations.
We are subject to fluctuations in the prices of our commodities, including raw materials, which could adversely affect our financial condition and results of operations.
We experience fluctuations in the cost of our raw materials, including aluminum, glass and wood. A variety of factors over which we have no control, such as global demand for aluminum, fluctuations in transportation costs, speculation in commodities futures, changes in laws or regulations, and the creation of new materials or products based on new technologies may affect the purchase and transportation costs and availability of raw materials that we use to manufacture DIRTT Solutions. These factors may also magnify the effect of economic cycles on our business. In addition, we have not historically entered into long-term agreements with vendors and, if we continue to do so, we may be exposed to short-term and long-term price fluctuations as a result.
Aluminum represents the largest component of our raw materials consumption. Substantial, prolonged upward trends in aluminum prices could significantly increase the cost of our aluminum needs and have an adverse effect on our financial condition and results of operations. We have experienced fluctuations in the price of aluminum and anticipate that these fluctuations will continue in the future. In 2018, the U.S. government imposed tariffs on steel and aluminum and limited the amounts of steel and aluminum coming into the United States based on the countries of origin of those imports. In 2018 and 2019, we sourced the majority of our aluminum from North America and sourced under 10% of our raw materials from outside North America. Nonetheless, tariffs and import limitations may increase the prices we pay for aluminum. Increases in the price that we pay for our commodities, including raw materials, could adversely affect our liquidity, operating margins, and financial condition.
We rely on a limited number of outside suppliers for certain key components and materials, and failure or delay in obtaining the necessary components or materials could delay or prevent the manufacturing or distribution of our DIRTT Solutions.
We rely on certain key suppliers for raw materials and components, including aluminum, glass and wood. We maintain multiple suppliers for key materials, although two suppliers accounted for approximately 32% and 21% of our aluminum supply for the year ended December 31, 2019. While we believe there are other vendors for most of our key requirements, certain materials meeting our quality standards are available only through a limited number of vendors. If we are required to obtain another source for these materials or components, we may not be able to obtain pricing on as favorable terms or on terms comparable to our competitors. Any failure or delay in obtaining the necessary raw materials in the quantities and quality required may result in increased costs and delays in manufacturing or distributing our products, which could have a material adverse effect on our liquidity, financial condition, or results of operations. A vendor may also choose, subject to existing contracts, to modify its relationship with us due to general economic concerns or specific concerns relating to that vendor or us, at any time. These modifications might include additional requirements from our suppliers that we provide them additional security in the form of prepayments or with letters of credit. Any significant change in the terms that we have with our key suppliers could materially and adversely affect our liquidity, financial condition, or results of operations.
