Independent Auditor’s Report

Partners

Krestmark Industries, L.P.

Dallas, Texas

We have audited the accompanying combined financial statements of Krestmark Industries, L.P. and affiliates, which comprise the combined balance sheets as of December 31, 2015 and 2014, and the related combined statements of income, changes in partners’ capital and cash flows for each of the three years in the period ended December 31, 2015, and the related notes to the combined financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these combined financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation and maintenance of internal control relevant to the preparation and fair presentation of combined financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on these combined financial statements based on our audits.  We conducted our audits in accordance with auditing standards generally accepted in the United States of America.  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the combined financial statements.  The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the combined financial statements, whether due to fraud or error.  In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the combined financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control.  Accordingly, we express no such opinion.  An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the combined financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the combined financial statements referred to above present fairly, in all material respects, the financial position of Krestmark Industries, L.P. and affiliates as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in accordance with accounting principles generally accepted in the United States of America.

Note 1:                                     Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations

Krestmark Industries, L.P. (Krestmark) was formed in the state of Texas as a limited partnership on April 1, 2004.  Krestmark earns revenues predominately from the manufacturing of aluminum and vinyl windows and doors.  Products are sold primarily to builders and distributors in the central and southern United States.  The combined affiliates are Crest Vinyl Extrusions, L.L.C. (Crest) and Legacy Vinyl Windows, LP (Legacy).  Crest was formed in the state of Texas as a limited liability company on July 18, 2013.  Crest earns revenues predominately from the manufacturing of vinyl window components.  To date the majority of Crest revenues have been generated through the sale of products to Krestmark.  Legacy was formed in the state of Texas as a limited partnership on September 10, 2014.  Legacy, which began operations in 2015, manufactures windows.  Krestmark, Crest and Legacy (collectively, the Company) have common management and ownership and therefore management has elected to present combined financial statements.

Principles of Combination

All significant intercompany accounts and transactions of the Company have been eliminated in the combined financial statements.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all liquid investments with original maturities of three months or less to be cash equivalents.  At December 31, 2015 and 2014, cash equivalents consisted primarily of money market accounts.

At December 31, 2015, the Company’s cash accounts exceeded federally insured limits by approximately $10,514,000.

Accounts Receivable

Accounts receivable are stated at the amount the Company expects to collect.  The Company provides an allowance for doubtful accounts, which is based upon a review of outstanding receivables, historical collection information and existing economic conditions.  Accounts receivable are ordinarily due 30 days after the issuance of the invoice.  Accounts past due more than 120 days are considered delinquent.  Interest is generally not charged on overdue receivables.  Delinquent receivables are written off based on individual credit evaluation and specific circumstances of the customer.

If the financial condition of the Company’s customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required.

Inventory Pricing

Inventories consist of raw materials, work-in-process and finished goods.  Inventories include costs of materials, labor and overhead.  Inventories are stated at the lower of cost or market.  If needed, the Company records a reserve for obsolete and slow-moving inventory based on current inventory levels and historical and expected future sales levels.

Property and Equipment

Property and equipment acquisitions are stated at cost less accumulated depreciation and amortization.  Depreciation and amortization is charged to expense on the straight-line basis over the estimated useful life of each asset.  Leasehold improvements are amortized over the shorter of the lease term or their respective estimated useful lives.

The estimated useful lives for each major depreciable classification of property and equipment are as follows:

Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized.  Expenditures for maintenance and repairs are charged to expenses as incurred.

Long-lived Asset Impairment

The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable.  If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value.  No asset impairment was recognized during the years ended December 31, 2015, 2014 and 2013.

Income Taxes

The Company is not a tax paying entity for federal or state (except Texas) income tax purposes.  Therefore, taxable income or loss is reported to the individual partners and members for inclusion in their respective tax returns and no provision for federal income is included in these statements.

The Company is subject to a franchise tax in the state of Texas.  Although the subject legislation states that the franchise tax is not an income tax, it has the characteristics of an income tax as it is determined by applying a tax rate to a base that considers both revenues and expenses.  Therefore, the Company accounts for the Texas franchise tax as an income tax.

With a few exceptions, the Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2011.

Revenue Recognition

Revenues are generally recorded at the time products are delivered and are reported net of returns and allowances.

Taxes Collected from Customers and Remitted to Governmental Authorities

Taxes collected from customers and remitted to governmental authorities are presented in the accompanying combined statements of income on a net basis.

Shipping and Handling Costs

Shipping and handling costs are included in cost of goods sold.

Deferred Rent

The Company’s operating leases for its warehouses and office space contain free rent periods and escalating payments during the lease terms.  For these leases, the Company recognizes rent expense on a straight-line basis over the minimum lease terms and records the difference between the amounts charged to expense and the rent paid as deferred rent.
