Thanks, Mike, and let me say that I am most appreciative to you and the Board of Directors for the opportunity over the last 4 years. ScanSource is a truly exciting growth company, and I am confident in its long-term success and the strategic initiatives that we have executed on.
As Mike indicated, first quarter financial results exceeded expectations. On Slide 6, net sales for the first quarter increased 7%, $930 million, and includes acquisitions. Net sales rebounded strongly from the June quarter, up $55 million and 6% quarter-over-quarter.
Our first quarter 2017 gross profit margin was 9.8% compared to 9.4% for the sequential quarter and 10.1% for the year-ago quarter, reflects the sales mix for more big deals and lower international margins. This can be seen more clearly in the segment financial charts on Slide 7 and 8, where the Worldwide Barcode, Networking and Security segment gross margins declined to 7.9% compared to 8.1% for the sequential quarter and 8.4% in the prior year quarter. The gross margin for the Worldwide Communications & Services segment of 13.9%, which includes Intelisys, reflects an improvement from 12.1% for the sequential quarter and 13.3% for the prior year quarter.
SG&A expenses, excluding amortization of intangible assets and acquisition costs, were $65 million or 7% of net sales compared to $59 million or 6.8% of net sales in the prior year quarter. This year-over-year increase includes expenses from the KBZ and Intelisys not in the prior year.
Our first quarter 2017 non-GAAP operating income was $26.7 million or 2.9% of net sales compared to $28.4 million or 3.3% in the prior year quarter. Sequentially, non-GAAP operating income improved from $18.9 million. Non-GAAP operating margins for the Worldwide Barcode & Security segment were basically unchanged from the prior year. Non-GAAP operating margins for the Worldwide Communications & Services decreased 60 basis points, in part from higher bad debt expense.
With the acquisition of Intelisys, we recorded a $95 million contingency consideration, reflecting the present value of expected future earn-out payments. For the first quarter 2017, we recorded a change in fair value of contingency consideration of $800,000. For the second quarter 2017, we expect the change in fair value of contingency consideration to total approximately $3.1 million.
In addition, we recorded intangible assets of $63 million, with related amortization of $0.5 million in the first quarter of 2017 and $1.6 million expected for the second quarter 2017. These purchase accounting entries will have a significant impact on the GAAP reported financials going forward but not on the non-GAAP. To illustrate, for the month of September, Intelisys was dilutive to GAAP EPS by less than $0.01 and added $0.03 for the non-GAAP EPS for the quarter.
Our effective tax rate was 34.8% for the first quarter 2017 and 34.5% for the prior year period. For the fiscal year 2017 forecast, we're using 34.8% effective tax rate. First quarter 2017 GAAP EPS of $0.58 increased $0.02 year-over-year and non-GAAP EPS of $0.68 was unchanged.
Average diluted shares for the first quarter 2017 totaled 25.8 million, down 8% from the year earlier period as a result of share repurchases.
Now shifting to the balance sheet and capital allocation plan. Our working capital, balance sheet and cash flow measures are referenced in Slides 9 and 10 in our presentation. One of the highlights from Slide 9 is $116.8 million of operating cash flow generated over the last 12 months. Although some of this relates to timing, the business teams have done an excellent job of improving our working capital by increasing inventory turns and reducing the paid-for inventory days.
Inventory turns improved to 6x compared to 5.3 turns a year ago. As you may recall in the prior year, we increased our inventory levels to support the SAP go-live implementation in North America. This decrease in inventory levels was part of our plan, and the team has executed well by achieving this. We expect continued improvements in working capital efficiency for the remainder of fiscal year 2017. The DSO excluding Intelisys came in at 59 days, higher than our typical range and primarily reflects the aging of customer-specific accounts in North America and Brazil.
One point of clarification relates to the Intelisys working capital model. We have included 2 months of accrued accounts commissions receivable and accrued accounts commissions payable on the balance sheet, as required by U.S. GAAP. These 2 accruals basically offset one another and therefore have no impact on our overall working capital results.
As Mike said earlier, the balance sheet remains very strong. At September 30, 2016, we had cash and cash equivalents of $45 million and debt of $166 million or net debt of $121 million. Our leverage totaled approximately 1x trailing 12-months adjusted EBITDA from increased debt following our acquisition of Intelisys. ROIC was 13.1% for the first quarter 2017. And again, as Mike mentioned earlier, regarding the full year, we expect strong growth in adjusted EBITDA and a higher ROIC compared to last year, partially from Intelisys. We paid $83.8 million for the initial cash purchase price of Intelisys and repurchased $17 million of shares. As of the end of the quarter, we had approximately $103 million remaining on our share authorization.
I would now like to turn the call back over to Mike.
