Background and Nature of Operations

Pentair Ltd., formerly known as Tyco Flow Control International Ltd. (as used prior to the Merger (as defined below), “Flow Control”), is a company organized under the laws of Switzerland. In these notes, the terms “the Company,” “Pentair,” “us,” “we” or “our” refer to Pentair Ltd. and its consolidated subsidiaries. Our business took its current form on September 28, 2012 as a result of a spin-off of Flow Control from its parent, Tyco International Ltd. (“Tyco”), and a reverse acquisition involving Pentair, Inc.

Prior to the spin-off, Tyco engaged in an internal restructuring whereby it transferred to Flow Control certain assets related to the flow control business of Tyco, and Flow Control assumed from Tyco certain liabilities related to the flow control business of Tyco. On September 28, 2012 prior to the Merger (as defined below), Tyco effected a spin-off of Flow Control through the pro-rata distribution of 100% of the outstanding common shares of Flow Control to Tyco’s shareholders (the “Distribution”), resulting in the distribution of 110,898,934 of our common shares to Tyco’s shareholders. Immediately following the Distribution, an indirect, wholly-owned subsidiary of ours merged with and into Pentair, Inc., with Pentair, Inc. surviving as an indirect, wholly-owned subsidiary of ours (the “Merger”). At the effective time of the Merger, each Pentair, Inc. common share was converted into the right to receive one of our common shares, resulting in 99,388,463 of our common shares being issued to Pentair, Inc. shareholders. The Merger is intended to be tax-free for U.S. federal income tax purposes. After the Merger, our common shares are traded on the New York Stock Exchange under the symbol PNR. Tyco equity-based awards held by Flow Control employees and certain Tyco employees and directors outstanding prior to the completion of the Distribution were converted in connection with the Distribution into equity-based awards with respect to our common shares and were assumed by us. Pentair, Inc. equity-based awards outstanding prior to the completion of the Merger were converted upon completion of the Merger into equity-based awards with respect to our common shares and were assumed by us.

The Merger was accounted for as a reverse acquisition under the purchase method of accounting with Pentair, Inc. treated as the acquirer, reflecting the control maintained by the executive management and board of directors of Pentair, Inc. after the Merger. As such, on the acquisition date of September 28, 2012, the assets and liabilities of Flow Control have been assessed at fair value and the assets and liabilities of Pentair, Inc. are carried over at historical cost. For periods prior to September 28, 2012, the Consolidated Statements of Operations and Comprehensive Income (Loss) and Consolidated Statements of Cash Flows include the historical results of Pentair, Inc. The consolidated financial statements include the results of Flow Control from the date of the Merger. Flow Control’s net sales and net loss from continuing operations for the period from the acquisition date to December 31, 2012 were $886.5 million and $117.0 million, respectively.

Our common share balances prior to the Merger have been adjusted to reflect the one-for-one conversion of the Pentair, Inc. shares to Pentair Ltd. shares, with the difference in par value recorded in Capital contribution reserve.

Based on the price of Pentair, Inc. common stock and our common shares issued on the date of the Merger, the purchase price was composed of the following:


In thousands
Value of common shares issued to Tyco shareholders ⁽¹⁾	$	4,811,363
Cash paid to Tyco shareholders in lieu of fractional common shares ⁽²⁾		542
Value of replacement equity-based awards to holders of Tyco equity-based awards ⁽³⁾		111,239


Total purchase price	$	4,923,144

(1)

Equals 110,886,444 Pentair Ltd. shares distributed to Tyco shareholders multiplied by the Merger date share price of $43.39.

(2)

Equals cash paid to Tyco shareholders in lieu of 12,490 Pentair Ltd. fractional shares multiplied by the Merger date share price of $43.39.

In accordance with applicable accounting guidance, the fair value of replacement equity-based awards attributable to pre-combination service is recorded as part of the consideration transferred in the Merger, while the fair value of replacement equity-based awards attributable to post-combination service is recorded separately from the business combination and recognized as compensation cost in the post-acquisition period over the remaining service period. The fair value of our equivalent stock options was estimated using the Black-Scholes valuation model utilizing various assumptions.

During the fourth quarter of 2012, we recorded fair value adjustments to our preliminary purchase price allocation, which resulted in an increase to goodwill of $32.6 million.

The purchase price has been preliminarily allocated based on the estimated fair value of net assets acquired and liabilities assumed at the date of the Merger. The preliminary purchase price allocation is subject to further refinement and may require significant adjustments to arrive at the final purchase price allocation. These adjustments will primarily relate to accounts receivable, inventories, property, plant and equipment, certain contingent liabilities and income tax-related items. We expect the purchase price allocation to be completed in the second quarter of 2013. There can be no assurance that such finalization will not result in material changes from the preliminary purchase price allocation. The purchase price is subject to a working capital and net indebtedness adjustment.

The following table summarizes our preliminary fair values of the assets acquired and liabilities assumed in the Merger:


In thousands
Cash and cash equivalents	$	691,702
Accounts and notes receivable		771,576
Inventories		1,046,165
Other current assets		98,212
Property, plant and equipment		822,001
Goodwill		2,520,110
Intangibles		1,425,072
Other non-current assets		275,103
Current liabilities		(856,341	)
Long-term debt		(914,530	)
Income taxes, including current and deferred		(364,573	)
Other liabilities and redeemable noncontrolling interest		(591,353	)


Total purchase price	$	4,923,144

The excess of purchase price over tangible net assets and identified intangible assets acquired was allocated to goodwill in the amount of $2.5 billion. Goodwill has been preliminarily allocated to our reporting segments as follows: $321.4 million to Water & Fluid Solutions, $1,342.6 million to Valves & Controls and $856.1 million to Technical Solutions. None of the goodwill recognized from the Merger is expected to be deductible for income tax purposes. Goodwill recognized from the Merger reflects the value of future income resulting from synergies of our combined operations. Identifiable intangible assets acquired as part of the Merger were $1.4 billion and include $362.3 million of indefinite life trade name intangibles and the following definite-lived intangibles: $905.7 million of customer relationships with a weighted average useful life of 14.2 years, $115.9 million of proprietary technology with weighted average useful life of 13.7 years and $41.2 million of customer backlog with a weighted average useful life of less than one year.
