Our Petroleum Segment's financial results are primarily affected by margin between refined product prices and prices for crude oil and other feedstocks. Historically, refining margins have been volatile and vary by region, and we believe they will continue to be volatile in the future. We do not produce crude oil and must purchase all of the crude oil we refine long before we refine it and sell the refined products to our customers. Price level changes during the period between purchasing feedstocks and selling the refined products from these feedstocks could have a significant effect on our financial results. The Market prices for these and other commodities depend upon a wide range of factors beyond our control, including regional and global supply of and demand for crude oil, gasoline, diesel, and other feedstocks and refined products, which supply and demand is subject to volatility based on, among other things, the availability and quantity of imports, the capacity and production levels of U.S. and foreign refineries and suppliers, levels of refined petroleum product inventories and the availability of petroleum alternatives, productivity and growth (or the lack thereof) of U.S. and global economies, U.S. foreign trade policy and relationships with foreign governments, political affairs, and the extent of governmental regulation, including executive orders. A decline in market prices of these feedstocks and refined products may negatively impact the carrying value of our inventories. In addition, the profitability of our Petroleum Segment is also subject to our ability to purchase crude oil at a discount to benchmark crude oils, such as WTI. Crude oil differentials can fluctuate significantly based upon overall economic and crude oil market conditions. Adverse changes in crude oil differentials can adversely impact our refining margins, earnings and cash flows. Further, the Petroleum Segment's purchases of crude oil, although based on WTI prices, have historically been at a discount to WTI because of the proximity of the Refineries to the sources, existing logistics infrastructure, and quality differences. Any changes to these factors could result in a reduction of the discount to WTI and may result in a reduction of the Petroleum Segment's cost advantage.
For example, as described further below, volatile commodity pricing and higher industry utilization and oversupply have had an unfavorable impact on our petroleum business and have negatively impacted our cash from operating activities and liquidity. As a result, in October 2024, the Board elected to suspend payment of the cash dividend, defer new growth capital spending, and reduce certain expected capital expenditures. Refer to Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources" of this Report for further discussion of our liquidity.
Additionally, our Renewables Segment is exposed to fluctuations in the prices of Vegetable oils and other feedstocks and renewable fuels, which are affected by numerous factors, such as Vegetable oil production capacity, system inventory, local and regional market conditions, inflation, and the operating levels of other facilities. Widespread expansion or upgrades of third-party facilities, price volatility, international political and economic developments, and other factors are likely to continue to play an important role in renewable fuel industry economics. These factors can impact, among other things, inventory levels in the market, resulting in renewable fuels price and product margin volatility.
Our Nitrogen Fertilizer Segment is exposed to fluctuations in nitrogen fertilizer demand in the agricultural industry. These fluctuations historically have had, and could in the future have, significant effects on prices across all nitrogen fertilizer products and, in turn, our results of operations, financial condition and cash flows. Nitrogen fertilizer products are commodities, the price of which can be highly volatile. A decrease in nitrogen fertilizer prices could have a material adverse effect on our business, cash flow, and ability to make distributions. The prices of nitrogen fertilizer products depend on a number of factors, including general economic conditions, cyclical trends in end-user markets, supply and demand imbalances, governmental policies, and weather conditions, which have a greater relevance because of the seasonal nature of fertilizer application. If seasonal demand exceeds the projections on which we base our production levels, customers may acquire nitrogen fertilizer products from competitors, and our profitability may be negatively impacted. If seasonal demand is less than expected, we may be left with excess inventory that will have to be stored or liquidated. Supply is affected by available capacity and operating rates, raw material costs, government policies and global trade.
In addition, the international market for nitrogen fertilizers is influenced by such factors as the relative value of the U.S. dollar and its impact upon the cost of importing nitrogen fertilizers, foreign agricultural policies, the existence of, or changes in, import or foreign currency exchange barriers in certain foreign markets, changes in the hard currency demands of certain countries, and other regulatory policies of foreign governments, as well as the laws and policies of the U.S. affecting foreign trade and investment.
We cannot predict future changes in U.S. policy with respect to foreign trade (including the imposition of trade barriers, tariffs on Canadian and other goods, or economic or trade sanctions, from the new administration or otherwise), including whether existing trade policies will be maintained or modified or whether the entry into new bilateral or multilateral trade agreements will occur, nor can we predict the effects that any such changes would have on our business. Changes in U.S. trade policy have resulted and could again result in reactions from U.S. trading partners, including adopting responsive trade policies which could make it more difficult or costly to obtain feedstocks or market our products. Such changes in U.S. trade policy or in laws and policies governing foreign trade, and any resulting negative sentiments towards the U.S. as a result of such changes, could materially and adversely affect our business, financial condition, results of operations and liquidity.
