What was the global effective tax rate for Terex in the second quarter of 2021
xample our new Genie micro scissors increases on the job productivity. Terex Utilities recently introduced a new bigger gear for construction and maintenance of the electric grid and MP continues to develop, implement and rollout digital solutions, such as Connected Dealer Inventory, Telematics and e-commerce.
Finally we are investing in inorganic opportunities for future growth. We recently completed two actions. First, we acquired a facility in China to localize production to meet increasing demand for our industry-leading mobile crushing and screening products and we are excited about the growth prospects in China. Second, we completed a bolt-on acquisition, purchasing MDS International, which is a well-established business of heavy duty aggregate trommels that broadens our product offerings. While this was not financially significant investment, it demonstrates our progress with inorganic growth, via bolt-on acquisitions, as we previously communicated. Terex is well positioned for growth in 2021 and beyond because we have strong businesses, strong brands and strong market positions. We continue to invest, including a new innovative products, digital capabilities and manufacturing capacity.
Turning to Slide 6. The AWP and MP segments continue to perform well, allowing us to capture the benefits from the positive market fundamentals that we are seeing. First in Genie, the current market dynamics point to a multi-year replacement cycle for access equipment. The average age of fleet globally is increasing and customers need to replenish their fleets, so the replacement cycle is kicking in. We are beginning to see positive indicators for nonresidential investment as well as continued strong order activity. Before wrapping up my comments regarding Genie, I am pleased that we announced earlier this week that Simon Meester, was named President of Genie. I thoroughly enjoyed working with Simon and the Genie team over the past year. Simon is the right leader for the Genie business.
Turning to our Utilities business. Demand is strong across its end markets of tree care, rental and investor-owned utilities. In addition, we are experiencing strong growth in our utilities parts and service business.
Next on Materials Processing. We expect global demand for crushing and screening equipment to continue to grow. Broad-based economic growth, construction activity and aggregates consumption, are the primary market drivers. We are seeing strong markets for the cement mixer, material handling and environmental businesses. In addition, global monetary and fiscal stimulus programs has supported stronger demand in our end markets. Overall, we are seeing robust market conditions around the world for our industry leading products and solutions.
With that, let me turn it over to Duffy.

Thanks John. Turning to Slide 7. Let's look at our second quarter results. Overall revenues of $1 billion were up 50% year-over-year with both of our operating segments revenues up significantly. For the quarter, we recorded an operating profit of $123 million compared to only $7 million in the second quarter of last year. We achieved an operating margin of approximately 12% from disciplined cost control and fulfilling as much customer demand as possible, given the realities of the global supply chain during the quarter.
The second quarter operating profit does include $4 million of benefits from the release of a financing receivable reserve and the recording about that receivable related to prior years, offset by a $1 million charge for business impairment and restructuring. Improved gross margins and lower SG&A as a percent to sales allowed Terex to expand operating margin significantly year-over-year. Interest and other expense was approximately $22 million higher than Q2 of last year driven by $26 million of costs in connection with the refinancing of a significant portion of our capital structure, offset by $4 million in interest savings.
