Poor’s and a Baa1 long-term rating from Moody’s. Our credit ratings are dependent, however, upon a number of factors, both qualitative and quantitative, and are subject to change at any time. The disclosure of our credit ratings is made in order to enhance investors’ understanding of our sources of liquidity and the impact of our credit ratings on our cost of funds. Based upon the preceding factors, and based on the fact that we were able to raise $1.0 billion of capital at attractive interest rates in April 2018, we expect to continue to have adequate access to the capital markets at a reasonable cost of funds for liquidity purposes when needed.
Our credit facility includes only one financial covenant, which is a limit of 60% on the ratio of funded debt to total capitalization. In addition, the credit facility contains customarynon-financial covenants, including a limit on Nucor’s ability to pledge the Company’s assets and a limit on consolidations, mergers and sales of assets. As of September 29, 2018, our funded debt to total capital ratio was 29%, and we were in compliance with allnon-financial covenants under our credit facility. No borrowings were outstanding under the credit facility as of September 29, 2018.
Our financial strength allows a number of capital preservation options. Nucor’s robust capital investment and maintenance practices give us the flexibility to reduce spending by prioritizing our capital projects, potentially rescheduling certain projects and selectively allocating capital to investments with the greatest impact on our long-term earnings power. Capital expenditures for 2018 are expected to be approximately $1.0 billion compared to $507.1 million in 2017. The increase in projected 2018 capital expenditures is primarily due to the fact that several major expansion projects are underway in 2018. The projects that we anticipate will have the largest capital expenditures in 2018 are the $230.0 million cold mill complex addition at Nucor Steel Arkansas, the $176.0 million hot band galvanizing line at Nucor Steel Gallatin, the two micro mill greenfield expansions in Sedalia, Missouri and Frostproof, Florida with a combined estimated cost of $490.0 million, and the $180.0 million merchant bar rolling facility at Nucor Steel Kankakee. In addition to these expansion projects, we also have an estimated $200.0 million project underway at Nucor Steel Louisiana for equipment and improvements.
In September 2018, Nucor’s Board of Directors declared a quarterly cash dividend on Nucor’s common stock of $0.38 per share payable on November 9, 2018 to stockholders of record on September 28, 2018. This dividend is Nucor’s 182nd consecutive quarterly cash dividend.
Funds provided from operations, cash and cash equivalents, short-term investments and new borrowings under our existing credit facilities are expected to be adequate to meet future capital expenditure and working capital requirements for existing operations for at least the next 24 months.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
In the ordinary course of business, Nucor is exposed to a variety of market risks. We continually monitor these risks and develop strategies to manage them.
Interest Rate Risk– Nucor manages interest rate risk by using a combination of variable rate and fixed rate debt. Nucor also occasionally makes use of interest rate swaps to manage net exposure to interest rate changes. Management does not believe that Nucor’s exposure to interest rate market risk has significantly changed since December 31, 2017. There were no interest rate swaps outstanding at September 29, 2018.
Commodity Price Risk – In the ordinary course of business, Nucor is exposed to market risk for price fluctuations of raw materials and energy, principally scrap steel, other ferrous and nonferrous metals, alloys and natural gas. We attempt to negotiate the best prices for our raw material and energy requirements and to obtain prices for our steel products that match market price movements in response to supply and demand. In periods of strong or stable demand for our products, we are more likely to be able to effectively reduce the normal time lag in passing through higher raw material costs so that we can maintain our gross margins. When demand for our products is weaker, this becomes more challenging. Our DRI facilities in Trinidad and Louisiana provide us with flexibility in managing our input costs. DRI is particularly important for operational flexibility when demand for prime scrap increases due to increased domestic steel production.
Natural gas produced by Nucor’s drilling operations is being sold to third parties to offset our exposure to changes in the price of natural gas consumed by our Louisiana DRI facility and our steel mills in the United States. For the nine months ended September 29, 2018, the volume of natural gas sold from our drilling operations was approximately 15% of the volume of natural gas purchased for consumption in our domestic steelmaking and DRI facilities.
