Thank you, and good morning. Net sales for the first fiscal quarter of 2016 were $142.3 million versus $113 million last year, up 26% from a year ago. Adjusted operating income was 20.7% or $29.5 million, resulting in an adjusted EPS of $0.78 per share versus $0.69 per share last year.
This quarter, we had approximately 2 months of contribution from Sargent Aerospace & Defense.
The breakdown of revenue components this period was 63% were aerospace revenues, 37% were industrial revenues. We're trending to 70%, 30% breakdown between industrial and aerospace, aerospace being the 70% and industrial being the 30% going forward.
Adjusted EBITDA of $37.3 million was generated during the period. Adjusted gross margin came in at 38.7% versus 38.8% last year. Pre-Sargent RBC margins were 39.8% versus 38.8% last year. Consolidated aerospace sales were up 45% for the quarter. And on RBC aerospace revenues, pre-Sargent, let's refer to them as "RBC classic" revenues, these were down 3.4%. This was driven mainly by defense. Last year, defense was unusually strong in the first quarter. The timing of orders this year versus last year played a role here, plus a small impact from currency.
Looking ahead, we see this sector strengthening each quarter this year as both the major plane OEMs have announced the step-up in production rates in calendar '16 and demand from defense customers normalizes, and actually, that demand will increase.
RBC classic aerospace OEM revenues were up a few percentage points, and the aftermarket revenues were 11% better than last year.
Turning to our industrial markets. Sales expanded 2.9%. Net of the contribution of Sargent, the Sargent acquisition, sales were down 5%. Industrial distribution sales were off 8% -- 8.1% driven principally by a lower demand from our Swiss business.
Demand for Swiss industrial products are off nationally as a result of the currency strengthening last January and the effect overall on industrial demand in Switzerland. Industrial demand for us is steady, but it's off.
Lower requirement for bearings from the oil aftermarket was also a contributor to the decline. And finally, currency played about a 1% role in this equation.
Total industrial OEM products were up 9.3%. Net of the Sargent contributions, sales were down 3.2%, with currency playing a small role and mining OEMs contributing to most of the decline.
As you remember, last year, our mining sales were strong in the first quarter as OEM recovered inventory positions that had been completed, and that's no longer happening.
Integration of the Sargent acquisition has begun with no surprises to report. We expect to see this business realignment as we integrate this business with RBC. Some of the units will be more efficiently aligned with RBC management's strengths, markets or geography and will fall more with the RBC management alignment than the historical Sargent management alignment.
Sargent has become a very active participant in the RBC of today. Early benefits are increased penetration at core accounts with additional products; new account introductions with immediate critical mass; a long list of product in-sourcing opportunities that fall well within our production competencies; design and testing expertise in important markets such as aerospace and defense that are well complemented by RBC's manufacturing skill base; and substantial new contracts at early stages of start-up that will be important contributors to the future.
I'll now turn the call over to Dan, who will provide more color on the quarter.
