Thank you, Richard. Our fourth quarter consolidated sales were $979 million, down 3% compared to the fourth quarter of last year. Full-year consolidated sales were $3.7 billion, up nearly 3%. On a constant currency basis, consolidated sales for the quarter were down 2% and, for the full year, were up 1%.
Results for the quarter and year were driven by strong growth in our B2B operations, including our Industrial Products Group, our North America and Europe B2B technology business, this strong growth in B2B was offset by weakness in our consumer channel sales.
Turning to our channels, our fourth quarter B2B channel sales grew 9% compared to last year. Our fourth quarter consumer channel sales declined 13%. Full-year B2B channel sales grew 12% compared to last year, and consumer channel sales declined 7%.
On a geographic basis, our fourth quarter North American sales were $698 million, a decrease of 4% compared to last year and accounted for 71% of our total sales.
Our fourth quarter European sales were $282 million, essentially flat compared to last year and accounted for 29% of our total sales.
Full-year North American sales grew 2% to $2.6 billion compared to last year, and European sales grew 5% to $1.1 billion.
Turning to our business units, in our Technology Products Group. Our Technology Products group's fourth quarter worldwide sales were down 5% to $895 million and up 1% to $3.4 billion for the full year compared to last year. Technology Products' fourth quarter operating income was $17.7 million or $18.3 million, excluding one-time charges, and $68 million for the full year or $62.4 million, excluding one-time gains.
Our European Technology business had modest fourth quarter sales growth on a local currency basis, driven by the U.K., Holland and Ireland markets. Our other European markets were soft, primarily as a result of the economic environment throughout Europe.
Overall, we had a strong bottom line performance in the quarter, driven by the U.K. and France operations as we benefited from opportunistic product purchases and efficiencies from our larger operating footprint.
Our North American technology B2B operations saw a mid-single-digit revenue increase in the quarter. We continue to benefit from IT upgrade trends and the investments in sales agents we made earlier in the year as agents worked through the typical ramp-up period in building their account books.
Going forward, we remain focused on converting web sales into managed accounts and prudently investing in our sales force.
Conversely, fourth quarter results for the North American consumer operations were soft, reflecting the competitive environment, freight promotional trends, the launch of our new private label business and reduced sales in our television shopping channel. We ended the year with 42 retail stores, unchanged from third quarter.
We are preparing for our grand opening of our second store in Puerto Rico next month, and we remain active in the evaluation of potential new store locations.
In our Industrial Products business, fourth quarter sales increased 27% to $83 million compared to last year. Full-year sales grew 28% to $320 million. Fourth quarter operating income grew 39% and 45% for the full year compared to last year.
We further expanded various product lines and ended the fourth quarter with 485,000 total investor SKUs, up nearly double the amount last year and up 10% sequentially. We continue to benefit from the scalability of our e-commerce infrastructure and make additional investments to support our growth.
In that regard, we will open a new outbound call center in the Western U.S. late in the first quarter of this year and are enhancing our logistics footprint to accommodate our growth.
Consolidated gross margins for the quarter grew to 14.3%, a 70 basis point improvement from last year. Gross margin for the full year grew to 14.4%, an 80 basis point improvement from last year. Consolidated operating margin for the quarter was up slightly at 2.1% and, for the full year, grew 30 basis points to 2.2%. Excluding one-time items, consolidated operating margin for the year was essentially flat.
Fourth quarter SG&A expense was 12.1% of sales versus 11.4% last year. Full year SG&A expense was 12.4% of sales versus 11.6% last year.
Special charges during the quarter were $0.6 million on a pretax basis or $0.01 per share after-tax and consisted primarily of legal and professional fees related to a previously disclosed investigation and settlement for the former executive.
Special net gains for the full year were $5.6 million on a pretax basis or $0.10 per share after-tax. The effective tax rate for the fourth quarter was 25.4%. For the full year, the effective tax rate was 30.9% compared to 35.6% last year.
The lower effective tax rate this year reflects the company having higher pretax income in France compared to last year. The pretax income in France is partially offset by the use of net operating loss carryforwards that have a full valuation allowance applied.
Earnings per diluted share totaled $0.40 for the quarter, up 18% compared to last year and were $1.47 for the full year, up 30%.
As of December 31, our balance sheet included $355 million of working capital, an increase of $54 million from last year, and $97 million in cash, an increase of $5 million from last year, reflecting our continuing efforts to proactively manage our balance sheet.
The current ratio at December 31 was 1.9:1 and total debt was less than $10 million. With that, we would like to open the call up for questions. Operator?
