Thanks, Mike. For the quarter, we delivered non-GAAP EPS of $0.76, within our expected range, while our net sales of $925 million fell below the low end of our expected range by $15 million. Next quarter, in our forecast, we are expecting higher net sales to include the timing of the large deals from this quarter, plus some additional sales.
First quarter GAAP diluted EPS, $0.16 per share, was well below our forecasted range. In the month of September, during the final earnout year for Network1, we made the determination to change the estimates and recorded $12.7 million in expense for the change in fair value of contingent consideration for Network1.
Consolidated net sales for the quarter decreased 1% to $925 million. The dollar impact on sales due to foreign currency translation was a positive $8 million, and acquisitions added $21 million to net sales. Organic net sales for both segments declined year-over-year, principally from lower big deals in North America as described earlier.
Gross profit dollars increased 16% year-over-year from higher gross margins, despite the lower sales. Our first quarter 2018 gross profit was 11.5%, up from 9.8% for the prior year, due to the addition of acquisition, lower big deals and better attainment of vendor programs.
On Slide 6 and 7, you can see our current quarter, sequential quarter and prior quarter margins by segment. SG&A expenses increased $9.9 million from the prior year quarter to $73 million for the first quarter of 2018. This increase reflects the addition of POS Portal and Intelisys, which was not fully reflected in the prior year quarter and to a lesser extent -- into a lesser extent, higher bad debt expense.
Our first quarter 2018 non-GAAP operating income was $30.6 million or 3.3% of net sales compared to $26.7 million or 2.9% in the prior year quarter. A key financial goal for fiscal year 2018 is to expand our non-GAAP operating margin. We have $103 million contingent consideration on our September 30, 2017, balance sheet, reflecting the present value of expected future earnout payments for our acquisition. For the first quarter, we recorded expense for the increase in fair value of contingent consideration of $16.9 million, which was much higher than expected from the $12.7 million for Network1 during the quarter.
For our second quarter 2018 forecast, we estimate the change in fair value of contingent consideration to be an expense of approximately $3 million, principally related to Intelisys.
Our effective tax rate was 39% for the first quarter of fiscal 2018, reflecting a $3 million -- sorry, reflecting a $300,000 item -- for a discrete item. Excluding the recognition of that discrete item, the effective rate for the quarter ended September 30, 2017, would have been 35.5%. For the second quarter fiscal year 2018 forecast, we are using a 35.3% effective rate. First quarter fiscal year 2018 net income was $4.1 million or $0.16 per diluted share, and non-GAAP net income of $19.4 million or $0.76 per diluted share.
Now shifting to the balance sheet and to the capital allocation plan. Our working capital balance sheet and cash flow measures are referenced on Slides 8 and 9 in our presentation. Cash from operations consumed $37 million this quarter, principally from higher inventory levels, and we have $51 million of operating cash flow generated over the last 12 months.
Our inventory, excluding POS Portal, decreased to 5.8x from 6.2x last quarter and 6x for the quarter ago -- for the year a quarter ago. The higher inventory levels include some strategic inventory purchases in inventory for big deals where the expected timing shifted to the December quarter.
Days sales outstanding, exiting POS Portal and Intelisys, came in at 63 days and reflects the aging of our receivables portfolio, primarily in North America. In addition, we experienced slower collections for our communications business in Latin America, including Brazil. And I want to note that our reseller financial services team worldwide has not changed our underwriting standards to take on more risk.
Our balance sheet remains very strong and continues to provide us with the ability to execute our capital allocation plan, which includes organic growth and strategic acquisitions. At September 30, 2017, we had cash and cash equivalent of approximately $24 million and debt of approximately $286 million for total net debt of approximately $262 million.
Our net leverage totaled roughly 2x trailing 12 months adjusted EBITDA, and our ROIC was 13% for the first quarter in fiscal 2018. On July 31, 2017, we closed on our acquisition of POS Portal and funded the initial cash purchase price of approximately $145 million with increased borrowings under our revolving credit facility. On August 8, 2017, we amended our revolving credit facility to increase committed borrowings from $300 million to $400 million. We now have a $400 million committed credit facility that matures April 3, 2022, to fund borrowings and to provide additional liquidity for investments.
Now turning to our forecast on Slide 10. We expect net sales for the second quarter fiscal 2018 to range from $950 million to $1.01 billion, GAAP diluted earnings per share to range from $0.54 per share to $0.60 per share and non-GAAP diluted earnings per share to range from $0.76 per share to $0.82 per share. Our forecast reflects mid-single-digit organic growth, a gross profit margin a little over 11% and includes POS Portal results for the full quarter. Our forecast also reflects higher average debt, principally from the POS Portal acquisition, including a $13.2 million earnout payment to be made on November 30. The higher average debt also leads to a higher borrowing rate and, therefore, higher interest expense for the quarter.
We expect foreign currency translation to positively impact sales for the December quarter by approximately $14 million. The foreign exchange rates used in our forecast are summarized in our presentation slides. I'd now like to turn the call back over to Mike for closing comments.
