All financial information and period-to-period references are on a continuing operations basis unless otherwise noted.  Reconciliations to discontinued operations and generally accepted accounting principles (GAAP) and non-GAAP reconciliations are provided in the attached financial tables. 2011 fourth quarter and year-to-date results have been recast to reflect Flomatic as a discontinued operation.

Fourth Quarter/Full Year Highlights:

·                  Fourth quarter 2012 sales were essentially flat compared with fourth quarter of 2011, with organic growth and acquired growth being substantially offset by the impact of negative foreign exchange, related primarily to a weakening of the euro against the U.S dollar.

·                  Adjusted 2012 fourth quarter EPS of $0.61 represents an increase of 8.9% over the fourth quarter of 2011.  Excluding the acquisition of tekmar Control Systems (tekmar), the net effect of the share repurchase program and the effect of the negative impact of a weakening euro, the increase was 4% over the fourth quarter of last year.

·                  Adjusted earnings were positively affected by a favorable blended tax rate in EMEA driven by the mix of earnings by country.

·                  Adjusted operating margin of 10.4% for the fourth quarter of 2012 was essentially flat with the fourth quarter of 2011; operating margins on a GAAP basis increased 1.2 percentage points to 8.6% in the fourth quarter of 2012, as compared to the fourth quarter of 2011.

·                  Full year 2012 sales increased mainly due to acquisitions and organic growth, offset substantially by a negative foreign exchange impact.  Full year sales were the highest since 2008.

·                  Adjusted 2012 full year EPS from continuing operations of $2.18 was flat with 2011. Excluding the results of acquisitions, the share repurchase program (net) and the effect of foreign exchange, adjusted EPS from continuing operations was $2.10, or 4% below 2011 adjusted EPS.

·                  2012 free cash flow of $104.8 million represented a 148% cash conversion rate of free cash flow to net income from continuing operations. 2012 is the fifth consecutive year that free cash flow has exceeded net income.

·                  Completed the disposal of Flomatic Corporation (Flomatic) in the fourth quarter of 2012, recognizing a net after-tax loss on disposal of approximately $3.8 million in discontinued operations.  Results for the years ended December 31, 2012 and 2011 have been recast to reflect Flomatic as a discontinued operation.  EPS was reduced by $0.02 for the full year 2012 and $0.01 for the full year 2011.

North American sales increased $8.9 million to $205.9 million in the fourth quarter of 2012, compared to $197.0 million for the fourth quarter of 2011.  This increase was due to an organic sales increase of $4.7 million, or 2.4%, acquired sales of $3.6 million and by favorable foreign exchange movements of $0.6 million associated with the strengthening of the Canadian dollar against the U.S. dollar.  Sales into the North American wholesale market were flat organically during the fourth quarter as compared to the same period in 2011.  Organic sales into the North American DIY home improvement market increased 9.0% for the fourth quarter of 2012 as compared to the fourth quarter of 2011, primarily from increased sales of residential and commercial products and water quality products.

Europe, Middle East and Africa (EMEA) sales decreased $9.1 million to $145.3 million for the fourth quarter or 2012, compared to $154.4 million for the fourth quarter of 2011.  The decrease was due to unfavorable foreign exchange movements associated with the weakening of the Euro versus the U.S. dollar of $5.7 million and a reduction in organic sales of $3.4 million or (2.2%).  Organic sales in the EMEA wholesale market increased by approximately 1% but were offset by a 4% reduction in OEM sales, as compared to the fourth quarter of 2011.  EMEA segment sales represented approximately 40% and 43% of total Company sales in the fourth quarters of 2012 and 2011, respectively.

The full year 2012 sales increase of $17.5 million was due to growth from acquisitions of $51.5 million and organic growth of $10.3 million, offset by unfavorable foreign exchange movements of $44.3 million.  Organic sales growth in North America of 1.9% was substantially offset by a decrease in EMEA organic sales of 1.5%.  Asia organic sales increased 18% for the year by expanded marketing and sales efforts in that region.

Full year free cash flow was $104.8 million in 2012, as compared to free cash flow of $105.6 million in 2011.  The conversion rate of free cash flow to net income from continuing operations was 148% as compared to 164% in 2011.  This is the fifth consecutive year that the Company generated free cash flows in excess of 140% of net income. At December 31, 2012, net debt to capitalization ratio was 10.7%, as compared to 13.9% at December 31, 2011, the decrease driven primarily by cash generation during the year. As of year-end, the Company had approximately $272 million of cash on hand and approximately $265 million in available credit under our credit agreement.

David J. Coghlan, Chief Executive Officer, commented, “We were pleased with our overall performance in the quarter.  Compared to the fourth quarter of 2011, our organic sales increased by approximately 1%, with increases in both the North America and Asia segments being offset by a decrease in the EMEA segment.  Adjusted operating margins of 10.4% were consistent with the third quarter driven by stronger sales than anticipated in North America.  Overall, this year again proved challenging for the end markets we serve as sales increased organically by only 1%. EMEA organic sales decreased by 1.5% for the year.  However, given the overall market environment within Europe, we were pleased with that result. In North America, we invested in our lead-free conversion program, which negatively affected 2012 results, but we expect positions us well for the future. We were also very pleased with our continued progress in Asia, as we saw 18% organic growth in 2012, albeit it from a small base.”

Mr. Coghlan concluded, “In closing, as part of our One Watts strategy we made some important investments in both people and systems which affected near-term operating margins but will position us well as we move ahead.  We took a leadership position in initiating the transition to lead-free products, which we believe will be an important driver in our industry for many years. We are seeing the start of a residential construction recovery in the U.S. and we expect Europe will continue to be a challenge.  However, we like our position in the expanding emerging Eastern Europe and Middle East export markets.  Lastly, we are starting to see some meaningful growth in our Asia business as we continue to invest and focus our efforts in leveraging the substantial market expansion opportunities we see there.”

In this press release we refer to non-GAAP financial measures (including adjusted operating income, adjusted operating margins, adjusted net income from continuing operations, adjusted earnings per share, adjusted earnings per share excluding acquisitions, share repurchases and foreign exchange impact, free cash flow, net debt to capitalization ratio and the cash conversion rate of free cash flow to net income from continuing operations) and provide a reconciliation of those non-GAAP financial measures to the corresponding financial measures contained in our consolidated financial statements prepared in accordance with GAAP. We believe that these financial measures are appropriate to enhance an overall understanding of our historical financial performance and future prospects. Adjusted operating income, adjusted operating margins, adjusted net income from continuing operations and adjusted earnings per share eliminate certain expenses incurred in the periods presented that relate primarily to our global restructuring programs, impairment charges, CEO separation costs and CFO retention costs, significant legal settlements, product liability and workers’ compensation accrual increases or decreases, acquisition earn out adjustments, due diligence costs, acquisition accounting costs, tax adjustments, and other costs and related tax benefits. Also, adjusted earnings per share excluding acquisitions, share repurchases and foreign exchange impact, exclude the effect of each of those items on adjusted EPS. Management then utilizes these adjusted financial measures to assess the run-rate of the Company’s continuing operations against those of comparable periods without the distortion of those factors.  Free cash flow and the net debt to capitalization ratio, which are adjusted to exclude certain cash inflows and outlays, and include only certain balance sheet accounts from the comparable GAAP measures, are an indication of our performance in cash flow generation and also provide an indication of the Company’s relative balance sheet leverage to other industrial manufacturing companies. The cash conversion rate of free cash flow to net income from continuing operations is also a measure of our performance in cash flow generation. These non-GAAP financial measures are among the primary indicators management uses as a basis for evaluating our cash flow generation and our capitalization structure. In addition, free cash flow is used as a criterion to measure and pay certain compensation-based incentives. For these reasons, management believes these non-GAAP financial measures can be useful to investors, potential investors and others. The Company’s non-GAAP financial measures may not be comparable to similarly titled measures reported by other companies. The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial measures prepared in accordance with GAAP.
