NOTES TO FINANCIAL STATEMENTS

Note 1 — Summary of Significant Accounting Policies

Company Activities and Operating Cycle — The Company is engaged in the energy services industry. A majority of its contracts are fixed-price type contracts that are completed within a year, although some may extend over one or more years.

Cash and Cash Equivalents — For the purposes of the statement of cash flows, the Company considers all short-term debt securities purchased with a maturity of three months or less to be cash equivalents.

Revenue Recognition — The Company’s revenue is derived primarily form providing engineering services under fixed-fee arrangements. The revenue is recognized on the percentage-of-completion method, measured by the proportion of costs incurred to date to estimated total costs for each job. This method is used because management considers costs incurred to be the best available measure of progress on jobs in process.

The costs of jobs in process include all direct material and labor costs and those indirect costs related to job performance. Selling, general and administrative costs are charged to expense as incurred. Provisions for estimated losses on uncompleted jobs are made in the period in which the revisions are determined. The costs of jobs in process are charged to earnings on the percentage-of-completion method used to recognize revenues.

The asset “Costs and estimated earnings in excess of billings on uncompleted contracts,” represent revenues recognized in excess of amounts billed. The liability “Billings in excess of costs and estimated earnings on uncompleted contracts,” represent billings in excess of revenues recognized.

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 that reporting period. Actual results could differ from those estimates.

S Corporation — Income Tax Status — The Company is organized as a Limited Liability Company in the State of Kansas, with the consent of its members, the Company has elected under the Internal Revenue Code to be an S Corporation. In lieu of corporate income taxes, the shareholders of an S Corporation are taxed on their proportionate share of the Company’s taxable income. Therefore, no provision or liability for federal income taxes has been included in the financial statements.

Advertising — The Company expense advertising production costs as they are incurred and advertising communication costs the first time the advertising takes place.

NOTES TO FINANCIAL STATEMENTS

Note 1 — Summary of Significant Accounting Policies (continued)

Trade Accounts Receivable — Trade accounts receivables are reported at the amount management expects to collect from outstanding balances. Differences between the amount due and the amount management expects to collect are reported in the results of operations of the year in which those differences are determined, with an offsetting entry to a valuation allowance for trade accounts receivable. Balances that still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to trade accounts receivable. Based on management’s assessment of the credit history with customers having outstanding balances and current relationships with them, it has concluded that accounts receivable is fully collectible; accordingly, no allowance for doubtful accounts is required.

Investments — The Company classifies its marketable securities as “available for sale.” Securities classified as “available for sale” are carried in the financial statements at fair value. Realized gains and losses, determined using the first-in, first-out (FIFO) method, are included in earnings; unrealized holding gains and losses are reported in other comprehensive income.

Fair value measurements - The Company has adopted the provisions of FASB ASC 320-10. Under this standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the “exit price”) in an orderly transaction between market participants at the measurement date.

In determining the fair value, the Company uses Level 1 valuation as defined in FASB ASC 320-10. Level 1 valuations are based on quoted prices in active markets for identical assets or liabilities that the Association has the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.

Note 2 — Concentration of Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of temporarily cash investments, accounts receivable due on contracts and costs and estimated earnings in excess of billings on uncompleted contracts. The company places its temporary cash investments with a financial institution; however for the year ended December 31, 2012, the Company had not limited its credit exposure with this financial institution for temporary cash investments in excess of FDIC depository insurance and repurchase agreements from the financial institution secured by securities guaranteed by the United States of America. The Company’s credit exposure for the year ended December 31, 2012 was $778,210.

NOTES TO FINANCIAL STATEMENTS

Note 2 — Concentration of Credit Risk (continued)

On November 9, 2010, the FDIC issued a Final Rule implementing section 343 of the Dodd-Frank Wall Street Reform and Consumer Protection Act that provides for unlimited insurance coverage of noninterest-bearing transaction accounts. Beginning December 31, 2010, through December 31, 2012, all noninterest-bearing transaction accounts are fully insured, regardless of the balance of the account, at all FDIC-insured institutions. The unlimited insurance coverage is available to all depositors, including consumers, businesses, and government entities. This unlimited insurance coverage is separate from, and in addition to, the insurance coverage provided to a depositor’s other deposit accounts held at an FDIC-insured institution.

The Company’s customers are mainly located within an approximate radius of 500 miles of Lawrence, Kansas. The Company is exposed to a regional concentration of credit risk in accounts receivable due on contracts in the amount of $154,506 as of December 31, 2012, and costs and estimated earnings in excess of billings in uncompleted contracts in the amount of $56,118 as of December 31, 2012.

Note 3 — Trade Accounts Receivable

Amounts due on contracts as of December 31, 2012, were as follows:

Note 4 — Investments

Available-for-sale securities are carried in the financial statement at fair value. Net unrealized holding losses on available-for-sale securities in the amount of $3,834 for the year ended December 31, 2012, have been included in accumulated other comprehensive income. All unrealized losses at December 31, 2012 were held less than 12 months.

The Company’s investment in marketable equity securities consists primarily of investment in open/closed end mutual funds. The unrealized losses does not impend on the Company’s evaluation of the fair value assessment to be other-than-temporary and the Company’s intent and ability to hold these investment for a reasonable period of time sufficient for a forecasted recovery of fair value at December 31, 2012.
