On our April investor call, we referenced rising inflation across our P&L at structurally high single digits with some select spikes of 150% to 200%.
In Q4, this raw material availability cost us an estimated $100 million in revenue.
Our full-year consolidated sales increased 11% to $6.1 billion, our EBIT margin increased by 150 basis points, and adjusted EBIT was up 26.5%.
Operating cash flow climbed nearly 40% to a record $766.2 million, and our adjusted EBIT margin climbed to 12.8%, which was also a record.
This team launched our MS-168 manufacturing system, which is allowing us to produce better products more quickly, more cost-effectively, and more sustainably.
In addition, we reduced our global manufacturing footprint by 28 facilities, consolidating production to more strategically advantageous plants.
Our original target was 31 plants but consolidation efforts were slowed by the COVID pandemic.
Through our financial realignment, we consolidated 46 accounting locations, improved controls, developed more effective and efficient accounting processes, and reduced costs.
Similar initiatives were undertaken in our IT infrastructure as we have migrated 75% of our organization to one to four group-level ERP platforms.
Over the course of the three-year MAP to Growth program, we have returned $1.1 billion of capital to shareholders through a combination of cash dividends and share repurchases.
While we have reached the 2020 MAP to Growth conclusion, there will be some runoff from the MAP to Growth program in fiscal '22, during which we expect to capture approximately $50 million in incremental savings.
Over the next six to 12 months, we will be working on a MAP 2.0 program in conjunction with our operating leaders.
We remain fully committed to achieving our long-term goal of a 16% EBIT margin, and we will be sharing more information about our progress for a new program in the coming quarters.
For the fourth quarter, we generated consolidated net sales of $1.74 billion, an increase of 19.6%, compared to the $1.46 billion reported in the year-ago period.
Sales growth was 13.9% organic, 2.2%, the result of recent acquisitions, and 3.5% due to foreign currency translation tailwinds.
Adjusted diluted earnings per share increased 13.3% to $1.28, compared to $1.13 in the fiscal 2020 fourth quarter.
Our adjusted EBIT was $236.2 million, compared to $213.6 million during the year-ago period, which was an increase of 10.6%.
If you exclude the impact of our nonoperating segment from both years, our four operating segments combined generated impressive sales growth of 19.6% and adjusted EBIT growth of 27.5% as they overcame margin pressures and supply availability challenges.
Construction products group net sales were a record $629.4 million during the fiscal 2021 fourth quarter, which was an increase of 33.2%, compared to fiscal 2020 fourth-quarter net sales of $472.4 million.
Organic growth was 28.4% and foreign currency translation provided a tailwind of 4.8%.
Adjusted EBIT was a record $110.4 million, compared to adjusted EBIT of $77.3 million reported during the year-ago period.
This represents an increase of 42.7%.
The segment's net sales were $283.3 million during the fiscal 2021 fourth quarter, which was an increase of 20.5%, compared to the $235.1 million reported a year ago.
Organic sales increased 12.9% and acquisitions contributed 2.9%.
Foreign currency translation increased sales by 4.7%.
Adjusted EBIT was $31 million during the fourth quarter of fiscal 2021, compared to $23.7 million during the year-ago period, representing an increase of 31.2%.
Our consumer group reported record net sales of $628.9 million during the fourth quarter of fiscal 2021, an increase of 2%, compared to net sales of $616.2 million reported in the fourth quarter of fiscal 2020.
Organic sales decreased 3.8% since this was the first quarter in which we comped against the surge in demand at the beginning of the pandemic.
Acquisitions contributed 3.8% to sales.
Foreign currency translation increased sales by 2%.
Fiscal 2021 fourth-quarter adjusted EBIT was $93.6 million, a decrease of 10.4%, compared to adjusted EBIT of $104.5 million reported during the prior-year period.
The specialty products group reported record net sales of $202.8 million during the fourth quarter of fiscal 2021, which increased 49.9%, compared to net sales of $135.2 million in the fiscal 2020 fourth quarter.
Organic sales increased 46.2% while acquisitions contributed 0.7% to sales and foreign currency translation increased sales by 3%.
Adjusted EBIT was a record $36.3 million in the fiscal 2021 fourth quarter, an increase of 395%, compared to adjusted EBIT of $7.3 million in the prior-year period.
Our fiscal 2021 cash flow from operations, as Frank mentioned, was a record $766.2 million, compared to last year's record of $549.9 million.
At year end, our total liquidity was $1.46 billion and included $246.7 million of cash and $1.21 billion in committed available credit.
Our net leverage ratio, as calculated under our bank agreements, was 2.17 as of May 31, 2021.
This was an improvement, as compared to 2.89 a year ago.
Total debt at the end of fiscal 2021 was $2.38 billion, compared to $2.54 billion a year ago.
Since the beginning of the fourth quarter, we repurchased approximately 38 million of stock.
As a result of the lag impact from our FIFO accounting methodology, we expect that our fiscal 2022 first-half performance will be significantly impacted by inflation throughout our P&L, which is currently averaging in the upper teens.
More importantly, the limited availability of certain key raw material components is negatively impacting our ability to meet demand.
Our most significant challenge for the first half of fiscal 2022 will be in our consumer group.
We expect consolidated sales to increase in the low to mid-single digits compared to Q1 of fiscal 2021 when sales grew 9%, creating a difficult year-over-year comparison.
Sales in our consumer group are expected to decline double digits as it continues to experience difficult comparisons to the prior year when organic growth was up 34%.
However, the consumer group's fiscal 2022 Q1 sales are expected to be above the pre-pandemic record, indicating that we have expanded the user base for our products since then.
Based on the anticipated decline in this one segment, our Q1 consolidated adjusted EBIT is expected to decrease 25% to 30% versus a difficult prior-year comparison when adjusted EBIT in last year's first quarter was up nearly 40%.
As discussed earlier, the challenges in this segment are anticipated to result in a significant decline in adjusted EBIT against difficult prior-year comparisons when sales were up 21% and adjusted EBIT was up 66%.
We anticipate that the Q2 decline in consumers will be mostly offset by the combined EBIT growth in our three other segments, leading to consolidated adjusted EBIT being roughly flat versus another difficult prior-year comparison when consolidated adjusted EBIT was up nearly 30%.

Summary:
For the fourth quarter, we generated consolidated net sales of $1.74 billion, an increase of 19.6%, compared to the $1.46 billion reported in the year-ago period.
Adjusted diluted earnings per share increased 13.3% to $1.28, compared to $1.13 in the fiscal 2020 fourth quarter.
