Thank you, Robert, and welcome again to our first quarter 2015 conference call. First, I'd like to remind everyone that our results for 2014 reflect the business as it existed when it was part of Kimberly-Clark. As a result, included in 2014 are pre-spin costs associated with execution of the spin-off. Let me start with some key information from our press release.
First quarter sales were $394 million, a 2% decrease in constant currency compared to the prior year. First quarter results reflect higher G&A expenses associated with becoming a standalone company. These costs are on plan as we establish our functional capabilities. With that, we had an adjusted operating margin of 11.6% for the quarter compared to prior year of 18.6%. Adjusted EBITDA was $55 million compared to $86 million in the prior year.
Now taking a more detailed look at our results for the first quarter. Overall sales of $394 million were down 4% compared to $411 million a year ago. Exchange rates negatively impacted net sales by 2% or approximately $10 million. Lower volumes and price each negatively impacted net sales by 1%.
Adjusted gross margin fell from 38% to 34.3%. Contributing to this decline were the dissynergies from the spin-off consistent with our plan. In addition, distribution expense was higher than anticipated as a result of the West Coast dock workers labor dispute, which led to supply chain inefficiencies across our U.S. network. During the quarter, we encountered more than 1,000 containers that required some type of redeployment or special handling to minimize customer impact.
Adjusted operating profit for the quarter was $46 million, down from $77 million a year ago. The decrease was driven by lower sales and gross margins mentioned earlier as well as increased G&A standalone costs, which are tracking to plan.
During the quarter, we realized a $12 million gain from the sale of one of our Thailand manufacturing facilities. This gain as well as $11 million in post-spin-related charges and $6 million in intangible amortization expense were excluded from adjusted operating profit. As a result, adjusted operating profit margin was 11.6% for the quarter. Adjusted diluted earnings per share for the quarter were $0.51.
Looking at our performance on a segment basis. First, S&IP net sales declined 8% in the quarter to $255 million, down 5% on a constant currency basis. The variability and the timing of distributor orders impacted our performance as customers and distributors worked through their prior quarter's inventory build.
As a result, we had lower volumes in protective apparel, exam gloves and surgical drapes and gowns, primarily in North America and in Europe, Middle East and Africa, or EMEA. Net selling prices were 1% lower, driven primarily by lower prices in exam gloves in North America as favorable commodity costs continue to make this a very competitive category.
For the quarter, S&IP operating profit of $20 million was lower compared to the prior year as a result of lower sales volumes in several product categories, unfavorable currency exchange rates, higher distribution costs and higher year-over-year spending on G&A related to standalone expenses.
Turning to our second segment, Medical Devices. Sales for the quarter were $122 million, down 6% compared to the prior year, which equates to a 4% decline on a constant currency basis. Volumes were lower by 3%. Changes in pricing and currency each negatively impacted performance by 1%.
I remain excited about the growth generated in interventional pain, up 23%, as our cooled radiofrequency business, branded COOLIEF, posted growth of 93% in North America. Volume growth in digestive health was up mid-single digits in EMEA and North America.
Overall surgical pain volume declined 14%, driven in part by competitive activity in North America. Also reflected in our surgical pain results are lower IV pump sales for the quarter as sales in the prior year quarter were strong due to the timing of distributor orders in both North America and EMEA.
In North America, the surgical pain market dynamics seem to be improving as we continue to execute our direct marketing and physician education programs that demonstrate the benefits and efficacy of our pain management portfolio. This, along with clinical evidence, which supports the effectiveness of our ON-Q therapy, gives us confidence that over time, surgical pain volumes will grow as more physicians seek nonnarcotic pain therapies that have proven better outcomes for patients.
Segment operating profit for the quarter was $25 million compared to $31 million a year ago. Our results were driven by lower sales and higher G&A expense related to standalone costs.
Turning to our balance sheet and cash generation. For the quarter, cash from operations was $40 million compared to $26 million a year ago. At quarter end, we had $166 million of cash on hand, $17 million higher than year-end despite a $20 million increase in capital spending due to investments to complete the transition from Kimberly-Clark. Overall, our capital spending is on plan.
In summary, for the quarter, net sales were down 2% on a constant currency basis. We generated positive cash flow, and we ended the quarter with $166 million of cash on the balance sheet. Our solid financial profile positions us to continue to execute our strategy of transforming our product portfolio to higher-margin Medical Devices.
Now I'll turn the call back to Robert to discuss our outlook for the balance of the year. Robert?
