STANADYNE HOLDINGS, INC. AND SUBSIDIARIES

STANADYNE CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

(dollars in thousands, except where noted otherwise)

(1) Business, Organization and Significant Accounting Policies

Description of Business. Stanadyne Holdings, Inc. (“Holdings”) owns all of the outstanding common stock of Stanadyne Intermediate Holding Corp. (“SIHC”). SIHC owns all of the outstanding common stock of Stanadyne Corporation (together with its consolidated subsidiaries, “Stanadyne”). A majority of the outstanding common stock of Holdings is owned by funds managed by Kohlberg Management IV, L.L.C. (“Kohlberg”). Collectively, Holdings, SIHC and Stanadyne hereinafter are referred to as the “Company.” Holdings and Stanadyne are separate reporting companies.

Holdings is a holding company with no operations beyond those of its indirectly, wholly-owned subsidiary, Stanadyne. Stanadyne is a leading designer and manufacturer of highly engineered, precision manufactured engine components, including fuel injection equipment primarily for diesel engines and, more recently for high pressure gasoline engines. Stanadyne sells engine components to original equipment manufacturers (“OEMs”) in a variety of applications, including agricultural and construction vehicles and equipment, industrial products, automobiles, light duty trucks and marine equipment. The aftermarket is a core element of Stanadyne’s operations. The Company sells replacement parts and units through various global channels to service its products, including the service organizations of its OEM customers, its own authorized network of distributors and dealers, and major aftermarket distribution companies.

Principles of Consolidation. The condensed consolidated financial statements of Holdings include the accounts of Holdings and all of Holdings’ direct and indirect wholly-owned subsidiaries: SIHC, Stanadyne, Stanadyne, SpA (“SpA”), and Stanadyne Changshu Corporation (“SCC”). The condensed consolidated financial statements of Stanadyne include the accounts of Stanadyne and Stanadyne’s wholly-owned subsidiaries: SpA and SCC. A joint venture, Stanadyne Amalgamations Private Limited (“SAPL”), is fully consolidated with Holdings and Stanadyne based on Stanadyne’s controlling share, while the remaining share is recorded as a non-controlling interest. Intercompany balances have been eliminated in consolidation.

Basis of Presentation. The condensed consolidated financial statements presented herein have been prepared in accordance with accounting principles generally accepted in the United States of America and, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement for the periods presented. The Company’s quarterly results are subject to fluctuation and consequently the results of operations and cash flows for any quarter are not necessarily indicative of the results and cash flows for any future period. For further information, refer to the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. These notes to condensed consolidated financial statements apply to both Holdings and Stanadyne unless otherwise noted.

Income Tax Accounting. For the three months ended March 31, 2013 and 2012, the Company applied an estimated annual effective tax rate to interim period pre-tax income (loss) to calculate the income tax expense (benefit) as the effective tax rate method provides a reliable estimate for computing income taxes in interim period. In addition to the effective annual tax rate, Stanadyne provided an additional discrete tax benefit for the impact of 2012 research and development credit resulting from the American Taxpayer Relief Act of 2012 enacted retroactively and signed into law on January 3, 2013. As of December 31, 2012, the Company had a valuation allowance of $3.9 million placed against deferred tax assets in India, China and Italy. It is reasonably possible that some or all of the existing valuation allowance may decrease within the next 12 months, primarily due to the Company’s ability to generate sufficient income prior to the expiration of those deferred tax assets. Although realization is not assured, management believes that during the next 12 months that some or all of these deferred tax assets will be realizable. The Company expects that any such changes would have a material impact on its annual effective tax rate.

Income tax benefit for Stanadyne in the first quarter of 2013 totaled $2.4 million and 43.9% of pre-tax loss versus an income tax expense of $0.6 million and 32.8% of pre-tax income in the first quarter of 2012. The effective income tax rates differed from the amount computed by applying the U.S. statutory rate of 35% to pre-tax (loss) income in the first quarter of 2013 and 2012. The difference resulted primarily from profitability in the foreign jurisdictions where the related tax impact was offset by corresponding changes in the foreign valuation allowances as well as by the tax benefit of research and development credits.

Income tax expense for Holdings in the first quarter of 2013 totaled $1.4 million and (15.9)% of pre-tax loss versus an income tax benefit of $0.1 million and 5.5% of pre-tax loss in the first quarter of 2012. The effective income tax rates differed from the amount computed by applying the U.S. statutory rate of 35% to the pre-tax loss in the first quarter of 2013 and 2012. The difference in 2013 resulted primarily from changes to the valuation allowances as well as non-deductible interest expense at Holdings. The difference in the effective tax rate as compared to the statutory rate for 2012 resulted primarily from non-deductible interest expense and from profitability in foreign jurisdictions where the related tax impact was offset by corresponding changes in the foreign valuation allowances.

Risks and Uncertainties. The Company’s financial position, results of operations and cash flows have been and may continue to be adversely affected by the global recession, significant volatility in the worldwide capital, credit and commodities markets, lower corporate profits and increased capital spending, and concerns about inflation. Holdings incurred consolidated net losses and negative cash flows from operations in each of the last three years and the three months ended March 31, 2013. Stanadyne incurred a net loss and negative cash flows from operations in the first quarter of 2013 and in 2011. Holdings and Stanadyne are both highly leveraged with total short-term and long-term debt of $312.2 million and $212.2 million, respectively, outstanding at March 31, 2013. The indenture governing Stanadyne’s Senior Subordinated Notes limits the amount of dividends that can be paid to an amount calculated under a Restricted Payments Basket (as defined by the terms of the indenture) (“RP Basket”). Holdings relies on dividends from SIHC which are received from Stanadyne to make semi-annual interest payments on its senior discount notes. Failure to make these interest payments would result in an event of default under the terms of the senior discount notes. Kohlberg has advised Holdings that it will provide financial assistance to Holdings, to the extent necessary, in meeting the semi-annual interest payments that will come due through February 15, 2014. If necessary, Kohlberg will provide Holdings with additional equity of up to $8.0 million. The Company believes that with cash and cash equivalents on hand, availability under the U.S. Revolver, expected operating cash flow, and limited financial assistance from Kohlberg, if necessary, it has sufficient liquidity over the next 12 months to meet its obligations. However, the factors described above create potential uncertainty, and management will continually monitor the Company’s revenues and operating cash flow against expectations. In the event the Company’s forecasts to generate sufficient operating cash flow are not realized, the Company may need to reduce headcount, reduce other spending, reduce or delay capital investments and product development, incur more indebtedness, restructure existing indebtedness, or raise additional equity capital, or a combination of these items, which may have a further negative impact on its business, results of operations, and cash flows. In addition, the Company’s current debt agreements limit its ability to incur additional indebtedness, so the ability to borrow additional money may be limited by the Company’s debt holders or by conditions in the credit markets.

(dollars in thousands, except where noted otherwise)

The fair values of the Senior Subordinated Notes and Holdings’ Senior Discount Notes are based on bid prices and are classified within Level 1 of the valuation hierarchy. The fair value of the Senior Subordinated Notes at March 31, 2013 and December 31, 2012 was $158.8 and $148.8 million, respectively. The fair value of Holdings’ Senior Discount Notes at March 31, 2013 and December 31, 2012 was $70.5 and $68.0 million, respectively. The fair values of the Company’s other borrowings approximated their recorded values at March 31, 2013 and December 31, 2012 based on similar borrowing agreements offered by other major institutional banks and are classified within Level 2 of the valuation hierarchy.

On February 13, 2013, Stanadyne and Jefferies Finance LLC (“Jefferies”) entered into a Second-Lien Term Loan Agreement (the “Term Loan Agreement”) providing for a term loan in an aggregate original principal amount of $25.0 million (with potential incremental term loans up to an additional $15.0 million in aggregate). The term loan is guaranteed by Stanadyne’s immediate parent, SIHC and is secured by a second-lien position in certain tangible and intangible assets of Stanadyne, including property, plant and equipment, fixed assets, copyrights, trademarks and patents. Covenants include restrictions on pre-payments, restrictions on dividends, and limitations on sales of assets and sale and leaseback transactions. The term loan bears interest at 10.0% per annum and matures on June 30, 2014. Interest only is payable quarterly. Prepayment may be required upon sales of assets or a change of control. Stanadyne has taken these actions in order to enhance its available liquidity during the production launch of new high pressure gasoline and diesel fuel pump products.

On August 13, 2009, Stanadyne (as borrower) and SIHC (as guarantor) entered into a revolving credit agreement (the “U.S. Revolver”) with Wells Fargo Capital Finance, LLC (“Wells Fargo”). The U.S. Revolver, as amended through 2012, provided for maximum borrowings of $55.8 million based on availability, as defined, and is secured by all Stanadyne and SIHC assets, as well as a pledge of 65% of Stanadyne’s stock in SpA, SAPL, and SCC. The U.S. Revolver is comprised of a domestic inventory and accounts receivable facility, a domestic fixed asset facility, a foreign accounts receivable sub-facility guaranteed by the Export-Import Bank of the United States and a guaranteed facility, as defined by the credit agreement. The terms of the agreement also allow the Company to permanently reduce the amount of available credit under the Guaranteed Facility, in increments of $1.0 million, with a 10 day notice, in the event equity infusions are made to Holdings at the direction of Kohlberg. Interest on borrowings under the U.S. Revolver is at a Base Rate (as defined by the agreement) or LIBOR, plus an applicable margin ranging between 1.25% and 1.75% through 2012, depending on the level of excess availability. All borrowings under the U.S. Revolver are due and payable on April 30, 2014. The U.S. Revolver is subject to a fixed charge coverage ratio covenant of 1.1 if availability is less than $4.0 million, and certain other affirmative and negative covenants common to an asset-backed loan agreement. The U.S. Revolver also limits the amount of dividends and other payments that can be made by Stanadyne to SIHC. Further, the Company is required to provide annual audited financial statements to the bank within 105 days of year end.

On February 13, 2013, Stanadyne and Wells Fargo entered into a Fifth Amendment to Credit Agreement (the “Fifth Credit Amendment”) and a Fifth Amendment to EXIM Guarantied Credit Agreement (the “Fifth EXIM Amendment”). The Fifth Credit Amendment increased the maximum revolver amount by $5 million, increasing the total commitment to $60.8 million. The Fifth Credit Amendment also increased interest rates by 0.25% based on levels of Availability (as defined by the Credit Agreement), and modified certain clauses within the inventory sub-facility to add an inventory block and within the accounts receivable sub-facility to increase the revolving line limit and to modify customer concentration limits. In connection with this amendment, Stanadyne also entered into a Fifth EXIM Amendment to incorporate the modifications added by the Fifth Credit Amendment into the EXIM Guarantied Credit Agreement. All other terms of the credit agreements were materially unchanged from the prior agreements.

As of March 31, 2013, the U.S. Revolver had Availability, as defined, of $35.2 million, after reflecting $11.2 million of borrowings and $3.5 million used for standby letters of credit, as well as other limitations related to inventory and accounts receivable.

(5) Pension Plans and Other Postretirement Health Care and Life Insurance Plans

The Company has a noncontributory defined benefit pension plan for eligible domestic employees and also has two nonqualified plans, which are designed to supplement the benefits payable to designated employees. The components of the net periodic pension expense for the periods shown are as follows:

	Three months ended March 31,
	2013			2012
Interest cost	$	1,260		$	1,403
Expected return on plan assets		(1,788	)		(1,602	)
Recognized net actuarial loss		925			732
Net periodic pension cost	$	397		$	533

The Company funds the pension plan in an amount at least equal to the minimum required contribution as determined by the plan’s actuaries, but not in excess of the maximum tax-deductible amount under Section 404 of the Internal Revenue Code. The Company may make discretionary contributions of any amount within this range based on financial circumstances and strategic considerations, which typically vary from year to year.

The Company contributed $0.8 million to the pension plan during the three months ended March 31, 2013. The Company expects the minimum required contributions to the pension plan to total approximately $4.1 million in 2013. The Company contributed $1.2 million to the pension plan during the three months ended March 31, 2012 and $5.0 million for the full year of 2012.

Postretirement Health Care and Life Insurance

The Company’s U.S. subsidiaries make available certain health care and life insurance benefits for eligible retired employees. The components of the net periodic benefit for the periods shown were as follows:

	Three months ended March 31,
	2013			2012
Service cost	$	7		$	9
Interest cost		20			27
Recognized net actuarial gain		(156	)		(171	)
Net periodic postretirement income	$	(129	)	$	(135	)

(6) Property, Plant and Equipment

During the first quarter of 2013, the Company consolidated its operations on the Windsor, Connecticut campus from three buildings to two buildings in an effort to reduce costs and better utilize the available space. The book value of the vacated building was depreciated down to its net realizable value, resulting in an additional $2.9 million of accelerated depreciation recognized in the quarter.

(7) Equity Compensation Plan

In 2004, Holdings established the 2004 Equity Incentive Plan (the “Option Plan”) to provide for the award of non-qualified stock options to attract and retain people who are in a position to make a significant contribution to the success of the Company and its subsidiaries. Awards granted under the Option Plan vest over a period of one to four years contingent upon achievement of certain financial performance targets as defined by the Option Plan and expire 10 years after the date of grant.

The Company uses a Black-Scholes option-pricing model to calculate the fair value of options. The key assumptions for this valuation method include the expected term of the option, stock price volatility, risk-free interest rate, dividend yield, exercise price, fair value of common stock, probability that financial targets will be met, and forfeiture rate. Many of these assumptions are judgmental and highly sensitive in the determination of compensation expense.

During the three months ended March 31, 2013 and 2012 , there were no stock options exercised, cancelled or granted.

For the three months ended March 31, 2013 and 2012, no compensation expense was recognized as management determined that it is not probable that the financial performance targets associated with the stock option awards will be achieved.

(8) Redeemable Non-controlling Interest and Financial Instruments

The expansion of manufacturing operations in SAPL in 2010 was funded through a combination of new debt and equity issuances. The process included entering into a put arrangement with the existing non-controlling interest partners as part of an amendment to the SAPL Joint Venture Agreement with respect to the common securities that represent the 35.1% non-controlling interest. The non-controlling partners have an option to put their ownership interests to Stanadyne during a 90-day period beginning March 1, 2015. Due to the put option, the non-controlling interest is redeemable and does not qualify as permanent equity. As a result, redeemable non-controlling interest is recorded in the mezzanine section of the condensed consolidated balance sheets and is reported at estimated redemption value. At March 31, 2013 and December 31, 2012, the redemption value was $1.0 million and $0.9 million, respectively. Changes in the redemption value are charged to retained earnings if available or to additional paid-in capital.

(9) Fair Value Measurements

Fair value, as defined in accounting guidance, is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In addition, fair value should be the exit price, or price received to sell the asset or liability as opposed to the entry price, or price paid to acquire an asset or assume a liability.

The following table below shows how the Company categorized certain financial assets and liabilities based on the types of inputs used in valuation techniques for measuring fair value:

	Fair Value Measurements at March 31, 2013
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Financial liabilities:
SAPL debenture embedded conversion option	$	—	$	—	$	1,157	$	1,157
	Fair Value Measurements at December 31, 2012
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Financial liabilities:
SAPL debenture embedded conversion option	$	—	$	—	$	1,150	$	1,150

The conversion option embedded in the SAPL debenture is considered a derivative and is recorded at its fair value. The value of the option is calculated using a Monte Carlo simulation approach, which takes into account certain assumptions which include the value of SAPL equity, the discount yield of 15.75%, volatility of 35% and risk free rate of 6.71%, among others. Increases or decreases in any of the input assumptions would not result in a material change to the fair value measurement of the SAPL debenture embedded conversion option.

An unrealized gain, which is included in other income in the condensed consolidated statement of operations, amounting to $8 and $58 was the only activity for Level 3 liabilities for the three months ended March 31, 2013 and 2012, respectively.

(10) Segments

The Company has one reportable segment. The Company manufactures its own proprietary products including fuel pumps for diesel and gasoline engines, injectors and filtration systems for diesel engines, and various non-proprietary products manufactured under contract for other companies. The Company’s proprietary products currently account for the majority of its sales.

(11) Commitments and Contingencies

The Company is involved in various legal and regulatory proceedings generally incidental to its business. While the results of any litigation or regulatory issue contain an element of uncertainty, management believes that the outcome of any known, pending or threatened legal proceeding, or all of them combined, will not have a material adverse effect on the Company’s consolidated financial position or results of operations.

The Company is subject to potential environmental liabilities as a result of various claims and legal actions, which are pending or may be asserted against the Company. Reserves for such liabilities have been established, and no insurance recoveries have been anticipated in the determination of the reserves. In management’s opinion, the aforementioned claims will be resolved without material adverse effect on the consolidated results of operations, financial position or cash flows of the Company. In conjunction with the acquisition of SIHC from Metromedia Company (“Metromedia”) on December 11, 1997, Metromedia agreed to partially indemnify Stanadyne for certain environmental matters. The effect of this indemnification is to limit the Company’s financial exposure for known environmental issues.

ITEM 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Management’s Discussion and Analysis of Financial Condition and Results of Operations reflects the results of operations and financial condition of Holdings and its subsidiaries, which are materially the same as the results of operations and financial condition of Stanadyne and its subsidiaries. Therefore, the discussions provided are applicable to both Holdings and Stanadyne except where otherwise noted.

We are a leading designer and manufacturer of highly-engineered, precision manufactured engine components. We manufacture our own proprietary products including fuel pumps for diesel and gasoline engines, injectors and filtration systems for diesel engines, and various non-proprietary products manufactured under contract for other companies.

Our business in the first quarter of 2013 continued to reflect the low levels of demand for our products sold in Europe, India and China that we began to experience in the second half of 2012. A number of factors have contributed to this lower level of demand. First, our major original equipment manufacturer (“OEM”) customers have indicated that the slow economies in those regions continue to limit demand for agricultural, industrial and construction equipment as well as on-highway vehicles that use our fuel injection and filtration products. Furthermore, decreases in U.S. government spending have reduced demand for our military style pumps sold to General Engine Products (“GEP”) for use on the HUMMWV. Finally, our independent aftermarket distribution network is reporting more than ample inventory levels now that the backlogged orders from 2012 have been filled. Sales for the three months ended March 31, 2013 totaled $54.4 million, reflecting a decrease of $13.8 million or 20.3% when compared to sales for the three months ended March 31, 2012. Sales to all of our OEMs and service customers were lower in the first quarter of 2013 when compared to the same period in 2012, with few exceptions. While demand in our base business was sluggish in this first quarter, we also received approval from General Motors (“GM”) to begin production of our new high pressure gasoline pump. Sales of this product totaled $1.3 million during the initial production ramp up period in the first quarter of 2013 and are expected to increase significantly through the rest of the year.

Stanadyne’s operating income in the first quarter 2013 totaled less than $0.1 million and 0.1% of sales , representing a decrease of $6.9 million from operating income of $7.0 million and 10.2% of sales in the first quarter 2012. This $6.9 million decrease in operating income was driven primarily by lower gross profits on the lower sales volumes in the first quarter of 2013, as well as $2.9 million of accelerated depreciation on a portion of our Windsor, Connecticut site that was vacated at the end of the quarter as a part of an overall campus consolidation initiative. Adjustments to the workforce in all of our locations were made in order to maintain a high level of manufacturing efficiency during the first quarter, despite the lower levels of production. Factory overhead was $0.8 million lower in the first quarter of 2013 when compared to the first quarter of 2012 due primarily to cost reduction actions implemented late last year in response to the lower levels of business. Our SG&A costs were $1.1 million lower in the first quarter 2013 when compared to the first quarter 2012, when we engaged consulting services to help us establish more effective management processes for the “new” global manufacturing organization established in 2011.

Liquidity remained sufficient in the first quarter 2013, with cash on hand as of March 31, 2013 totaling $1.3 million and availability under the U.S.-based revolving credit facility of $35.2 million, after reflecting $11.2 million of borrowings and $3.5 million used for standby letters of credit, as well as other limitations related to available inventory and accounts receivable. Stanadyne’s operating cash flows in the first quarter 2013 improved by $1.2 million compared to the first quarter 2012, due primarily to lower working capital requirements. To ensure sufficient liquidity during the new product launches in 2013, in February the Company amended the terms of the U.S. Revolver to increase the overall facility by $5.0 million and entered into a $25 million term loan agreement with Jefferies Finance, LLC. Although the Company’s cash flows from operations in 2013 may continue to be pressured by lower customer demand for our products, cash requirements for capital expenditures for our new high pressure gasoline and diesel pump product launches, and interest payments on our outstanding debt, this added liquidity should be sufficient for the next twelve months. Refer to “Liquidity and Capital Resources” for further information regarding our liquidity.

Comparison of Results of Operations

The Three Months Ended March 31, 2013 for Holdings and Stanadyne Compared to

The Three Months Ended March 31, 2012 for Holdings and Stanadyne

Net Sales. Sales in the first quarter 2013 totaled $54.4 million and were $13.8 million or 20.3% less than sales of $68.3 million in the first quarter 2012. Demand from our customers in China, Europe and India was much lower in the first quarter of 2013 due to sluggish economies in those regions. Additionally, sales were lower in the first quarter 2013 when compared to the comparable period a year earlier that included $3.9 million of sales for past due orders that accumulated in 2011 during the manufacturing reorganization.

Sales by Category

(dollars in millions)

	OEM Sales			%			Service Sales			%			Total Sales			%
Three months ended March 31, 2012	$	35.5			52.0		$	32.8			48.0		$	68.3			100.0
Three months ended March 31, 2013		25.7			47.3			28.7			52.7			54.4			100.0
Change	$	(9.8	)		(27.5	)	$	(4.1	)		(12.5	)	$	(13.8	)		(20.3	)

Sales to OEM customers decreased to $25.7 million and represented 47.3% of our first quarter 2013 revenues as compared to $35.5 million and 52.0% of our first quarter 2012 revenues. Sales to most OEM customers decreased in the first quarter 2013. One notable exception was the start of production and sales of our new high pressure gasoline pump to GM. First quarter sales to GM during the initial months of the ramp up totaled $1.3 million. Sales to Deere were $9.0 million lower, reflecting a combination of reduced demand for our products used in their agriculture, construction, forestry equipment, and utility tractors, as well as a $3.1 million of OEM sales included in first quarter 2012 for past due orders that accumulated in 2011 during the manufacturing reorganization. Sales to GEP were $1.0 million less in the first quarter of 2013 as compared to the first quarter of 2012 due to lower demand for our fuel pumps used to power the military HUMMWV.

Sales to service customers in the first quarter 2013 totaled $28.7 million and 52.7% of total revenue as compared to $32.8 million and 48.0% of our first quarter 2012 revenue. This $4.1 million decrease in first quarter service sales was due primarily to lower demand from Deere and our independent distribution network. Additionally, sales were lower in the first quarter of 2013 when compared to the comparable period a year earlier that included $1.1 million of sales for past due orders that accumulated in 2011 during the manufacturing reorganization. All of the remaining past due orders were filled during the first quarter of 2013, and our major distributors reported more than adequate inventory levels relative to market demand.

Cost of Goods Sold and Gross Profit. Gross profit totaled $9.4 million and 17.2% of net sales in the first quarter 2013 compared to $17.6 million and 25.7% of net sales in the first quarter 2012. This $8.2 million reduction in gross profit was due to the following increases and decreases in first quarter 2013 cost of goods sold when compared to the first quarter 2012 cost of goods sold:

Decreases in gross profit -
Lower sales volume and market/product mix	-	$	5.9
Higher factory overhead expenses in China	-	$	0.3
Accelerated depreciation	-	$	2.9
Increases in gross profit -
Overhead cost reductions in U.S. operations	+	$	0.9

Approximately $5.9 million of the decrease in first quarter 2013 gross profit was due to lower year-over-year sales volumes in both the OEM and service markets. Operational efficiencies improved in the first quarter 2013 when compared to the same period in 2012.

Factory overhead costs in the U.S. operations were $0.9 million lower overall in the first quarter 2013 when compared to the same period last year, reflecting cost reduction actions taken in response to the lower production requirements. Factory overhead costs in our China operations were $0.3 million higher in the first quarter of 2013 when compared to the same period in 2012, reflecting the added cost needed to support the fuel injector manufacturing operations transferred from our U.S. factories during 2012.

STANADYNE CORPORATION AND SUBSIDIARIES

Depreciation expense in the first quarter 2013 was $2.9 million greater than the same period in 2012. In the first quarter of 2013, the Company committed to a plan to consolidate the remaining operations on its Windsor, Connecticut campus by the end of the quarter. This plan allowed the Company to vacate one of its buildings, resulting in a decrease in operating costs and a more efficient utilization of available space. The book value of the vacated building and the related building improvements was depreciated down to its salvage value, resulting in $2.9 million of additional depreciation expense in the first quarter of 2013.

Selling, General and Administrative Expenses (“SG&A”). Stanadyne’s SG&A costs decreased by $1.1 million to $8.6 million and 15.8% of sales in the first quarter 2013 from $9.7 million and 14.2% of sales in the first quarter 2012. In the fourth quarter 2012, we discontinued utilizing outside consulting services to assist us with establishing operational and management processes for the reorganized operations in the U.S., which decreased SG&A costs by $1.5 million in the first quarter of 2013 when compared to the same period in 2012. This decrease was partially offset by a $0.4 million increase in realized and unrealized losses on foreign currency denominated positions in our international operations. Research and development costs were relatively unchanged in the first quarter of 2013.

Amortization of Intangible Assets. Amortization of intangible assets totaled $0.7 million in the first quarter 2013 and 2012.

Management fees. There were no fees charged to the Company by Kohlberg & Company L.L.C. for management services in the first quarter 2013, due to the low levels of business. Management fees were $0.2 million in the first quarter 2012.

Operating Income. Stanadyne’s operating income for the first quarter 2013 totaled less than $0.1 million and 0.1% of sales as compared to operating income of $7.0 million and 10.2% of net sales in the first quarter 2012. This $6.9 million decrease in operating income resulted from $8.2 million lower gross profit driven primarily by lower sales volumes and accelerated depreciation on our Windsor, Connecticut operations, partially offset by a $1.1 million decrease in our first quarter SG&A costs as well as a $0.2 million reduction in our first quarter management fees.

Income tax expense (benefit). Income tax benefit for Stanadyne in the first quarter 2013 totaled $2.4 million and 43.9% of pre-tax loss versus an income tax expense of $0.6 million and 32.8% of pre-tax income in the first quarter 2012. The effective income tax rates differ from the amount computed by applying the U.S. statutory rate of 35% to pre-tax income (loss) in the first quarter 2013 and 2012. The difference results primarily from profitability in foreign jurisdictions where the related tax impact is offset by corresponding changes in the valuation allowances. Additionally, the tax benefit for the first quarter of 2013 includes the tax benefit impact of a 2012 research and development credit resulting from the American Taxpayer Relief Act of 2012 enacted retroactively and signed into law on January 3, 2013.

Income tax expense for Holdings in the first quarter 2013 totaled $1.4 million and 15.9% of pre-tax loss versus an income tax benefit of $0.1 million and 5.5% of pre-tax loss in the first quarter 2012. The effective income tax rates differ from the amount computed by applying the U.S. statutory rate of 35% to the pre-tax loss in the first quarter 2013 and 2012. The difference results primarily from profitability in foreign jurisdictions where the related tax impact is offset by corresponding changes in the valuation allowances. Further, a percentage of Holdings interest expense is not deductible for income tax purposes.

Liquidity and Capital Resources

Our principal sources of liquidity are cash and cash equivalents on hand, which totaled $1.3 million on March 31, 2013, and cash flows from operations, supplemented, as needed, by our short term financing arrangements described below.

Our revolving credit agreement with Wells Fargo Capital Finance, LLC (“U.S. Revolver”) provides for borrowings of up to $60.8 million, based on Availability, as defined, and is secured by all Stanadyne and SIHC U.S.-based assets, as well as a pledge of 65% of Stanadyne’s stock in SpA, SAPL, and SCC. There was $11.2 million borrowed under the U.S. Revolver as of March 31, 2013. As of March 31, 2013, the U.S. Revolver had Availability of $35.2 million, after reflecting $11.2 million of borrowings and $3.5 million used for standby letters of credit, as well as other limitations related to available inventory and accounts receivable.

Indebtedness for Stanadyne as of March 31, 2013 totaled $212.2 million and was comprised of $160.0 million of Notes, $25.0 million of U.S. term debt, $11.2 million of borrowings under the U.S. Revolver, $9.2 million in foreign overdraft and revolving credit facilities, $1.3 million of SAPL debentures and $5.5 million in foreign term loans. The U.S. Revolver is subject to a fixed charge coverage ratio covenant test if availability is less than $4.0 million, and certain other affirmative and negative covenants common to an asset-backed loan agreement. The U.S. Revolver also limits the amount of dividends and other payments that can be made by Stanadyne.

On February 13, 2013, the U.S. Revolver was amended to increase the maximum availability by $5 million, increase interest rates and modify certain clauses within the inventory sub facility to add an inventory block and within the accounts receivable facility to increase the eligible collateral and to update customer concentration limits.

Also on February 13, 2013, Stanadyne and Jefferies Finance LLC (“Jefferies”) entered into a Second-Lien Term Loan Agreement (the “Term Loan Agreement”) providing for a term loan in an aggregate original principal amount of $25 million (with potential incremental term loans up to an additional $15 million in aggregate). The term loan is guaranteed by Stanadyne’s immediate parent, SIHC and is secured by a second-lien position in certain tangible and intangible assets of Stanadyne, including property, plant and equipment, fixed assets, copyrights, trademarks and patents. Covenants include restrictions on pre-payments, restrictions on dividends, and limitations on sales of assets and sale and leaseback transactions. The term loan bears interest at 10.0% per annum and matures on June 30, 2014. Interest only is payable quarterly. Prepayment may be required upon sales of assets or a change of control. Stanadyne has taken these actions in order to enhance its available liquidity during the production launch of new high pressure gasoline and diesel fuel pump products.

Indebtedness for Holdings as of March 31, 2013 totaled $312.2 million comprised of the same debt balances for Stanadyne, plus an additional $100.0 million of Discount Notes. The Discount Notes accreted to their full face value in August 2009 and carry a 12% coupon that is payable semi-annually in February and August. The payments are made by Holdings via dividends paid by SIHC which are received from Stanadyne. These dividends must be in compliance with the terms of the U.S. Revolver and the indenture governing the Notes.

Our financial position, results of operations and cash flows have been and may continue to be adversely affected by the global recession, significant volatility in the worldwide capital, credit and commodities markets, concerns about inflation, lower corporate profits and increased capital spending. Holdings incurred consolidated net losses and negative cash flows from operations in each of the last three years and the three months ended March 31, 2013. Stanadyne incurred a net loss and negative cash flows from operations in 2011 and in the first quarter of 2013. Holdings and Stanadyne are both highly leveraged with total short-term and long-term debt of $312.2 million and $212.2 million, respectively, outstanding at March 31, 2013. The indenture governing Stanadyne’s Senior Subordinated Notes limits the amount of dividends that can be paid to an amount calculated under a Restricted Payments Basket (as defined by the terms of the indenture) (“RP Basket”). Holdings relies on dividends from SIHC which are received from Stanadyne to make semi-annual interest payments on its senior discount notes. Failure to make these interest payments would result in an event of default under the terms of the senior discount notes. Kohlberg has advised Holdings that it will provide financial assistance to Holdings, to the extent necessary, in meeting the semi-annual interest payments that will come due through February 15, 2014. If necessary, Kohlberg will provide Holdings with an equity infusion of up to $8.0 million. The Company believes that the combination of cash and cash equivalents on hand, availability under the U.S. Revolver, expected cash flows from operations, and ongoing liquidity initiatives will provide sufficient liquidity over the next 12 months to meet its obligations. However, the factors described above create potential uncertainty, and management will continually monitor the Company’s revenues and operating cash flows against expectations. In the event the Company’s forecasts to generate sufficient operating cash flows are not realized, the Company may need to reduce headcount, reduce other spending, reduce or delay capital investments and product development, incur more indebtedness, restructure existing indebtedness, raise additional equity capital, or a combination of these items, which may have a further negative impact on its business, results of operations, and cash flows. In addition, the Company’s current debt agreements limit its ability to incur additional indebtedness, so the ability to borrow additional money may be limited by the Company’s debt holders or by conditions in the credit markets.

Cash Flows from Operating Activities. Stanadyne’s cash flows from operating activities consumed $5.3 million cash during the three months ended March 31, 2013 as compared to $6.5 million cash consumed during the same period of 2012. Lower cash requirements for working capital accounts were partially offset by lower operating income, resulting in $1.2 million less cash consumed by operating activities in the three months ended March 31, 2013 versus the comparable period in 2012.

Changes in asset and liability accounts, primarily working capital accounts, consumed $5.3 million less cash in the three months ended March 31, 2013 versus the same period in the prior year. The significant changes to our working capital accounts were as follows:

• Cash flows from changes in accounts receivable required $2.8 million less cash in the three months ended March 31, 2013 when compared to the three months ended March 31, 2012, due primarily to lower sales in the three months ended March 31, 2013 versus the same period in 2012. These lower levels of accounts receivable were partially offset by slower payments from our customers in Europe and India. The average days sales outstanding increased from 52.3 days at the end of the first quarter 2012 to 61.0 days at the end of the first quarter 2013. Stanadyne continues to carefully manage customer credit and collections activities.

• Cash flows from changes in inventory levels required $1.0 million more cash in the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. Inventory increased in the three months ended March 31, 2013 by $0.5 million, as compared to a $0.5 million decrease in the three months ended March 31, 2012. Inventory levels in the first quarter of 2013 increased primarily in support of the growing production requirements in the U.S. operations for our new high pressure gasoline pumps for GM. Business activity in our international operations in China, India and Italy was lower in the three months ended March 31, 2013 resulting in $0.9 million of positive cash flows from lower levels of inventory. Inventory turnover for Stanadyne for the three months ended March 31, 2013 totaled 5.5x, compared to the 5.4x turns realized for the three months ended March 31, 2012.

• Cash flows from changes in other current asset accounts consumed $0.7 million more cash in the three months ended March 31, 2013 than in the same period of 2012, due primarily to amounts incurred for production tooling that will be reimbursed by our customers later in the year, as well as changes in timing of deposits and annual prepaid expenses.

• Cash flows from changes in accounts payable balances provided $3.9 million more cash in the three months ended March 31, 2013 than the same period in 2012. Accounts payable balances increased by $3.3 million in the three months ended March 31, 2013 versus the $0.7 million decrease in accounts payable balances in the same period in 2012 due to a higher value for purchased materials related to the production ramp up in our gasoline pump program, as well as amounts owed for new capital equipment that will be paid in the second quarter 2013.

• Cash flows from changes in all other asset and liability accounts provided $0.3 million more cash in the three months ended March 31, 2013 than in the comparable period of 2012. This difference was due primarily to amounts accrued in 2013 for our employee bonus plans, partially offset by a $0.7 million reimbursement of cash to Holdings, representing the amounts paid in prior years for stock options exercised by former employees.

Cash flows from operating activities for Holdings in the three months ended March 31, 2013 were $5.3 million less than the amount reported for Stanadyne due to $6.0 million of interest payments made for the Discount Notes reduced by the $0.7 million of cash reimbursed from Stanadyne.

Cash Flows from Investing Activities. Cash flows from investing activities for the three months ended March 31, 2013 totaled $3.7 million and were $2.3 million more than the three months ended March 31, 2012. Capital expenditures were $3.6 million during the three months ended March 31, 2013 compared to $1.5 million during the three months ended March 31, 2012. These higher capital expenditures were primarily for equipment needed to produce the new high pressure gasoline pump for GM. Capital expenditures are expected to increase during 2013 as we install the remaining equipment in our U.S. plants to support the gasoline pump program and acquire equipment for our China operation to produce diesel common rail fuel pumps.

Cash Flows from Financing Activities. Stanadyne’s cash flows from financing activities in the three months ended March 31, 2013 provided $7.4 million in cash compared to $7.8 million in cash provided in the three months ended March 31, 2012.

Cash flows from financing activities in our U.S. operations in the three months ended March 31, 2013 included $25.0 million of proceeds from a new term loan with Jefferies partially offset by $1.5 million of debt origination costs, as well as $9.9 million of net cash payments against the U.S. Revolver, $5.3 million of dividends paid by Stanadyne, and other cash flows from financing activities in our international operations described below.

Cash flows from financing activities in SAPL during the three months ended March 31, 2013 consumed $1.2 million of cash for payments against outstanding revolving loan and term loan commitments of $0.7 million and $0.5 million, respectively. Cash flows from financing activities in SpA included $0.4 million net cash proceeds provided by overdraft borrowings used to finance working capital requirements and $0.1 million in payments of capital lease obligations. Cash flows from financing activities in SCC included $0.2 million of cash provided by short term banker acceptance borrowing arrangements.

Cash flows from financing activities for Holdings in the three months ended March 31, 2013 included the amounts reported for Stanadyne less the dividends paid by Stanadyne.

Pension Plans. We maintain the Stanadyne Corporation Pension Plan, a qualified defined benefit pension plan (the “Pension Plan”), which covers substantially all domestic hourly and salary employees and the Supplemental Retirement Benefit Plan, an unfunded nonqualified plan that provides benefits in excess of amounts permitted to be paid under the provisions of the tax law to participants in the Pension Plan.

The value of the invested Pension Plan assets grew to $95.5 million at March 31, 2013, representing a $4.9 million increase from the $90.6 million value at December 31, 2012. The Company contributed $0.8 million to the Pension Plan during the three months ended March 31, 2013 and expects the minimum required contributions to the Pension Plan to total approximately $4.1 million in 2013. The Company contributed $1.2 million to the Pension Plan in the three months ended March 31, 2012 and $5.0 million for the full year of 2012.

Critical Accounting Policies

We prepare our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. As such, we are required to make certain estimates, judgments and assumptions that we believe are reasonable based upon the information available. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. The issues involving significant accounting policies which we believe are the most critical to aid in fully understanding and evaluating our reported financial results include: product warranty reserves, inventory valuation adjustments for excess or obsolescence, realization of goodwill and other long-lived assets, pension and postretirement benefit liabilities, workers’ compensation liabilities, self-insurance reserves and determination of income tax balances including valuation allowances.

Product Warranty. The Company provides an accrual for the estimated future warranty costs of its products at the time the sale is recognized. These costs are based upon analyses of historical experience of product returns and the related cost.

Inventories. Inventories are stated at the lower of cost or market. The principal components of costs included in inventories are materials, labor, subcontract costs and overhead. The Company uses the last-in/first-out (“LIFO”) method of valuing its inventory, except for the inventories of SpA, SAPL and SCC, which are valued using the first-in/first-out (“FIFO”) method. Application of purchase accounting to the Company’s inventories in conjunction with the 2004 change in control resulted in a base year LIFO inventory value that was greater than the current FIFO inventory value. The LIFO inventory reserve value represents the amount necessary to state the Company’s U.S.-based inventories valued on a FIFO to LIFO basis.

Impairment of Long-Lived Assets, Goodwill and Other Intangible Assets. The Company evaluates the carrying value of long-lived assets (including property and equipment, goodwill and other intangible assets) when events or circumstances warrant such a review. Goodwill and intangible assets with indefinite lives are tested for impairment annually during the fourth fiscal quarter each year or more often if events or circumstances indicate a reduction in the fair value below the carrying value. Goodwill is allocated and reviewed for impairment by reporting unit. The goodwill is allocated to the reporting unit in which the business that created the goodwill resides. To test for goodwill impairment, the carrying value of the reporting unit is compared with its fair value. If the carrying value of the goodwill or long-lived asset is considered impaired, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the asset.

Pension and Other Postretirement Benefits. The Company amortizes unrecognized gains and losses exceeding 10% of the accumulated benefit obligation for the pension plans and for the health and life insurance benefits over the average remaining service period of the plan participants. This period approximates the period during which the benefits are earned. This amortization method of postretirement benefit obligations distributes gains and losses over the benefit period of the participants, thereby minimizing any volatility caused by actuarial gains and losses.

Self-Insurance Reserves. The Company is self-insured for a substantial portion of its health care and workers’ compensation insurance programs. With advice and assistance from outside experts, reserves are established using estimates based on, among other factors, reported claims to date, prior claims history, and projections of claims incurred but not reported. Future medical cost trends are incorporated in the projected costs to settle existing claims. If actual results in any of these areas change from prior periods, adjustments to recorded reserves may be required.

Income Taxes. Income taxes are accounted for in accordance with the asset and liability method. Stanadyne is included in the consolidated federal income tax return filed by Holdings. In accordance with its historical tax accounting policy, taxes for Stanadyne are recorded as if they had been calculated on a separate company basis. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the tax basis of assets and liabilities and their financial reporting amounts and are measured at the current enacted tax rates. A valuation allowance is assessed and recorded when realization of the deferred tax asset is not more likely than not. A valuation allowance is assessed for Stanadyne on the basis of its projected separate return results and is recorded when realization of deferred tax assets is not more likely than not.
