The December 31, 2017, Condensed Consolidated Balance Sheet amounts have been derived from the previously audited Consolidated Balance Sheet of Kaman Corporation and subsidiaries (collectively, the “Company”), but do not include all disclosures required by accounting principles generally accepted in the United States of America ("US GAAP"). In the opinion of management, the condensed consolidated financial information reflects all adjustments necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the interim periods presented. All such adjustments are of a normal recurring nature, unless otherwise disclosed in this report. Certain amounts in prior year financial statements and notes thereto have been reclassified to conform to current year presentation. The statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The results of operations for the interim periods presented are not necessarily indicative of trends or of results to be expected for the entire year.

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230) - Restricted Cash". The objective of this standard update is to address the diversity in classification and presentation of changes in restricted cash on the statement of cash flows. Under this ASU, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption was permitted. The adoption of this standard update had no impact on the Company's consolidated financial statements.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory". Under this ASU, income tax consequences of an intra-entity transfer of an asset other than inventory is recognized when the transfer occurs. The standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption was permitted. The adoption of this standard update did not have a material impact on the Company's consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments". This standard update was issued to address diversity in practice in how certain cash receipts and cash payments are presented and classified. The provisions of ASU 2016-15 will beare effective for interim and annual periods beginning after December 15, 2017. Early adoption was permitted. The adoption of this standard update did not have a material impact on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities”. The objective of this standard update is to remove inconsistent practices with regards to the accounting for financial instruments between US GAAP and International Financial Reporting Standards (“IFRS”). The standard update intends to improve the reporting model for financial instruments to provide users of financial statements with more decision-useful information. The provisions of this standard update are effective for interim and annual periods beginning after December 15, 2017. The adoption of this standard update had no impact on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASC 606"). The objective of this standard update is to remove inconsistent practices with regard to revenue recognition between US GAAP and IFRS. The standard intends to improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. The provisions of ASU No. 2014-09 are effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted for annual periods beginning after December 15, 2016. On January 1, 2018, the Company adopted ASC 606 using the modified retrospective method. As a result, the Company applied ASC 606 only to contracts that were not completed as of January 1, 2018. The adoption of ASC 606 resulted in a net reduction to opening retained earnings of approximately $9.6 million, net of tax, on January 1, 2018.

In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The objective of this standard update is to simplify the subsequent measurement of goodwill, eliminating Step 2 from the goodwill impairment test. Under this ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, assuming the loss recognized does not exceed the total amount of goodwill for the reporting unit. The standard update is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. The impact of the adoption of this standard update is dependent on the Company's goodwill impairment assessment.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. Under this ASU as amended, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting is largely unchanged under this ASU as amended. This standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company has developed a project plan that includes a three-phase approach to implementing this standard update. Phase one, the assessment phase, was completed in the third quarter of 2017. The Company began the second phase in the fourth quarter of 2017, which includes implementing new lease administration software, establishing policies and understanding the initial financial impact this standard update will have on the Company's consolidated financial statements. Phase three, which the Company anticipates beginning in the second half of 2018, will include integrating the standard update into financial reporting processes and systems and developing a more robust understanding of the financial impact of this standard update. The Company anticipates the ASU will have a material impact on its assets and liabilities due to the addition of right-of-use assets and lease liabilities to the balance sheet; however, it does not expect the ASU to have a material impact on the Company's cash flows or results of operations.

Under ASC 606, the amount of revenue recognized for any goods or services reflects the consideration that the Company expects to be entitled to receive in exchange for these goods or services. To achieve this core principle, the Company applies the following five step approach: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to performance obligations in the contract; and (5) recognize revenue when or as a performance obligation is satisfied.

A contract is accounted for when there has been approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance obligations under a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. In certain instances, the Company has concluded distinct goods or services should be accounted for as a single performance obligation that iswhen they are a series of distinct goods or services that have the same pattern of transfer to the customer. To the extent a contract includes multiple promised goods or services, the Company must apply judgment to determine whether the customer can benefit from the goods or services either on their own or together with other resources that are readily available to the customer (the goods or services are distinct) and if the promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract (the goods or services are distinct in the context of the contract). If these criteria are not met, the promised services are accounted for as a single performance obligation. The transaction price is determined based on the consideration that the Company will be entitled to in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price, generally utilizing the expected value method. Determining the transaction price requires significant judgment. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis. Standalone selling price is determined by the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Performance obligations are satisfied either over time or at a point in time as discussed in further detail below. In addition, the Company's contracts with customers generally do not include significant financing components or non-cash consideration.

In certain instances, the Company has accounted for contracts using the portfolio approach, a practical expedient permissible under the standard. The determination of when the use of the portfolio approach is appropriate requires judgment from management based on consideration of all the facts and circumstances. The Company uses the portfolio approach when the effect of accounting for a group of contracts or a group of performance obligations would not differ materially from considering each contract or performance obligation separately. This determination requires the use of estimates and assumptions that reflect the size and composition of the portfolio. The Company primarily uses the portfolio approach within its over time revenue streams throughout the Distribution segment as well as for its commercial bearings and structures, and defense bearings and structures businesses.businesses in the Aerospace segment. The Company's primary criteria considered when using the portfolio approach areis the commonality of economic factors, which generally follow the product type based on consistent production costs and standard pricing for the products.

The Distribution segment has historically recognized the majority of its revenue when the sales price was fixed, collectability was reasonably assured and the product's title and risk of loss had transferred to the customer. This method of revenue recognition remains substantially the same as revenue will be recognized at the point in time when title transfers to the customer, as this is when the performance obligations are generally controlled by the customer. A small percentage of revenue within the Distribution segment, specifically certain contracts for value-add services, engineering services and repairs, are accounted for over time under ASC 606. For the over time contracts within ourthe Distribution segment, revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company generally uses the cost-to-cost measure of progress for its contracts because it best depicts the transfer of assets to the customer which occurs as cost is incurred under the contracts. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company performs detailed quarterly reviews of the progress and execution of its performance obligations under certain larger contracts. As part of this process, management reviews information, primarily its estimated costs at completion and costs incurred to date by its vendors as a majority of production costs at the segment are incurred by third party vendors. These estimated costs are included in ourthe calculation of the measures of progress towards completion.

Additionally, the Company includes freight costs charged to customers in net sales and the correlating expense as a cost of sales. Sales tax collected from customers is excluded from net sales in the Company's Condensed Consolidated Statements of Operations.

The majority of long-term contracts in the Aerospace segment were historically accounted for under the percentage-of-completion method using units-of-delivery as a measurement basis. Many of these contracts moved to an over time revenue model under ASC 606. For example, revenue for the Company's Joint Programmable Fuze ("JPF") program with the U.S. Government ("USG") moved from percentage-of-completion using units-of-delivery as the measurement basis to the over time revenue recognition model using input costs as the basis for recognizing progress to completion. Conversely, revenue for the K-MAX® program moved from cost-to-cost revenue recognition under percentage-of-completion accounting to the point-in-time method, with revenue on these aircraft being recognized upon delivery to the end customer. For certain programs, early-contract unit costs in excess of the average expected cost over the life of the contract and general and administrative costs were previously capitalized and amortized over the period of performance of the contract. With the adoption of this standard update, $32.5 million of previously capitalized deferred costs in excess of the contract average and previously contractually recoverable general and administrative costs were adjusted within the cumulative effect to retained earnings and will not be amortized into earnings after January 1, 2018.

To determine the appropriate revenue recognition model for the Aerospace segment's long-term contracts, the Company evaluates whether a contract exists, considering whether multiple contracts should be combined as one single contract and then whether the contract should be accounted for as more than one performance obligation. This evaluation requires significant judgment, as these decisions could change the amount of revenue and profit recorded in a given period. For certain programs, the Company may promise to provide distinct goods or services within a contract, in which case these are separated into more than one performance obligation.

For many of thecertain programs in the Aerospace segment, the Company recognizes revenue over time because of continuous transfer of control to the customer. For USG contracts, this continuous transfer of control to the customer is supported by clauses in the contract that provide lien rights to the customer over the work in progress, thereby control transfers as costs are incurred. For non-USG contracts, the customer typically controls the work in progress because the Company is producing products that do not have an alternative use to the Company and where contractual termination clauses provide the Company rights to payment for work performed to date plus a reasonable profit.

Revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company generally uses the cost-to-cost measure of progress for its contracts because it best depicts the transfer of assets to the customer which occurs as cost is incurred under the contracts. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Total estimated contract costs generally include labor, materials and subcontractors’ costs, other direct costs and related overhead costs. These estimates also include the estimated cost of satisfying offset obligations, as required under certain contracts. The complexity of certain programs as well as technical risks and uncertainty as to the future availability of materials and labor resources could affect the Company’s ability to accurately estimate future contract costs.

For contracts that recognize revenue over time, the Company performs detailed quarterly reviews of the progress and execution of its performance obligations under these contracts. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes in estimates of revenues and costs. The risks and opportunities include management's judgment about the ability and cost to achieve the schedule (e.g. the number and type of milestone events), technical requirements (e.g., a newly-developed product versus a mature product) and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to complete the performance obligation (e.g. to estimate increases in wages and prices for materials and related support cost allocations), execution by subcontractors, the availability and timing of funding from customers and overhead cost rates, among other variables. Based upon these reviews, the Company will record the effects of adjustments in profit estimates each period. If at any time management determines that in the case of a particular contract total costs will exceed total contract revenue, a provision for the entire anticipated contract loss is recorded at that time. The amount of revenue recognized in the three-month and six-month fiscal periodperiods ended March 30,June 29, 2018 from performance obligations satisfied (or partially satisfied) in previous periods was $1.6 million. This amount was$1.4 million and $3.0 million, respectively. These amounts were primarily related to changes in the estimates of the stage of completion of Aerospace contracts, more specifically the JPF contract with the USG, the AH-1Z contract and the AH-1Z contract.SH-2G contract with Peru. For the three-month and six-month fiscal periodperiods ended March 31,June 30, 2017, there was awere net increaseincreases in the Company's operating income of $1.0 million fromattributable to changes in contract estimates. This increase wasestimates of $1.1 million and $2.1 million, respectively. These increases were primarily a result of improved performance on the JPF USG Program, the AH-1Z program and AH-1Z contracts.the SH-2G program with Peru. These improvements were partially offset by cost growth on certainthe K-MAX® contracts.and A-10 programs.

Due to the nature of the work required to be performed on many of the Company's performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. From time-to-time the Company enters into long-term contracts with the USG that contain award fees, incentive fees or other provisions that can either increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. The Company estimates variable consideration at the most likely amount to which it expects to be entitled. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company's anticipated performance and all information (historical, current and forecasted) that is reasonably available. The Company does not include financing components as variable consideration if less than one year. At March 30,June 29, 2018, the Company did not have any significant financing components.

Contracts are often modified to account for changes in contract specifications and requirements. The Company considers contract modifications to exist when the modification either creates new or makes changes to the existing enforceable rights and obligations. Contract modifications for goods or services that are not distinct from the existing contract are accounted for as if they were part of that existing contract. In these cases, the effect of the contract modification on the transaction price and the measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis, except when such modifications relate to a performance obligation that is a series of substantially the same distinct goods or services. If the modification relates to a performance obligation for a series of substantially the same distinct goods or services, the modification is treated prospectively. Contract modifications for goods or services that are considered distinct from the existing contract are accounted for as separate contracts. The Company applied the practical expedient for any contracts that were modified prior to January 1, 2018; therefore, the contracts were not restated retrospectively for those modifications.

For other contracts within the Aerospace segment, excluding the long-term contracts discussed above, the method of revenue recognition will remain substantially the same under ASC 606. For these contracts, revenue will be primarily recognized at the point in time when the title transfers to the customer, as this is when the performance obligation is controlled by the customer. Additionally, a small percentage of revenue related to certain contracts for repairs and overhauls within the Aerospace segment is accounted for over time under ASC 606. Under these contracts, revenue is generally recognized as work is performed in proportion to the actual costs incurred as compared to total estimated contract costs.

For the three-monthsix-month fiscal period ended March 30,June 29, 2018, the Company realized changes of asset and liability accounts as described above, with no impact to the Company's cash flows from operating activities.

For the three-month and six-month fiscal periodperiods ended March 30,June 29, 2018, the only adjustmentadjustments to comprehensive income when comparing the balances with ASC 606 and the balances without ASC 606 included the adjustmentadjustments to net earnings.earnings presented above.

The Company's receivables, net, consist of amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. The Company maintains an allowance for doubtful accounts, which reflects management’s best estimate of probable losses inherent in the trade accounts receivable and billed contracts balance. Management determines the allowance based on known troubled accounts, historical experience and other currently available evidence.

The Company's contract assets include unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is applied and revenue recognized exceeds the amount billed to the customer, and right to payment is not just subject to the passage of time. Amounts do not exceed their net realizable value. Contract assets are generally classified as current as such amounts are billable and collectible within twelve months.

Contract costs consist of costs to obtain and fulfill a contract. Costs to fulfill a contract primarily consist of nonrecurring engineering costs incurred at the start of a new program for which such costs are expected to be recovered under existing and future contracts. Such costs are amortized over the estimated revenue amount of the contract. Costs to obtain a contract consist of commissions and agent fees paid in connection with the award of a contract. If these costs are determined to have an amortization period of less than one year, the Company applies the practical expedient and the related costs are expensed as incurred. If the amortization period is determined to be greater than a year and the incremental costs to obtaining the contract qualify as an asset, then the contract costs are recorded and amortized over the estimated contract revenue. At March 30,June 29, 2018, costs to fulfill a contract and costs to obtain a contract were $9.8$9.5 million and $6.1$6.8 million, respectively. These amounts are included in contract costs, current portion and contract costs, noncurrent portion on the Company's Condensed Consolidated Balance Sheets at March 30,June 29, 2018.

The Company's contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue. Advance payments and billings in excess of revenue recognized are classified as current or noncurrent based on the timing of when recognition of revenue is expected. At March 30,June 29, 2018, the noncurrent portion of contract liabilities was $81.7$76.3 million, which is included in contract liabilities, noncurrent portion in the Company's Condensed Consolidated Balance Sheets.

The decrease in commercial and other government contracts cost and accrued profit - not billed was primarily attributable to the adoption of ASC 606.

Contract assets consist of unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. Contract costs consist of costs to obtain and fulfill a contract. Costs to fulfill a contract primarily consist of nonrecurring engineering costs incurred at the start of a new program for which such costs are expected to be recovered under existing and future contracts. Such costs are amortized over the estimated revenue amount of the contract. Costs to obtain a contract consist of commissions and agent fees paid in connection with the award of a contract. Contract liabilities consist of advance payments and billings in excess of costs incurred and deferred revenue.

Contract assets includes amounts for matters such as contract changes, negotiated settlements and claims for unanticipated contract costs. These amounts are as follows:

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date.

The Company uses a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: 

The following table presents the carrying value and fair value of financial instruments that are not carried at fair value:

The above fair values were computed based on quoted market prices and discounted future cash flows (observable inputs), as applicable. Differences from carrying values are attributable to interest rate changes subsequent to when the transactions occurred.

The fair values of cash and cash equivalents, accounts receivable, net and accounts payable - trade approximate their carrying amounts due to the short-term maturities of these instruments.

The Company holds derivative instruments for foreign exchange contracts that are measured at fair value using observable market inputs such as forward rates and ourits counterparties’ credit risks. Based on these inputs, the derivative instruments are classified within Level 2 of the valuation hierarchy. At March 30,June 29, 2018, the derivative instruments have been included in other current assetsliabilities on the Condensed Consolidated Balance Sheets. At December 31, 2017, the derivative instruments were included in other current assets and other assets on the Condensed Consolidated Balance Sheets. Based on the Company's continued ability to trade and enter into forward contracts and interest rate swaps, we considerthe Company considers the markets for ourits fair value instruments to be active.

The Company is exposed to certain risks relating to its ongoing business operations, including market risks relating to fluctuations in foreign currency exchange rates and interest rates. Derivative financial instruments are recognized on the Condensed Consolidated Balance Sheets as either assets or liabilities and are measured at fair value. Changes in the fair values of derivatives are recorded each period in earnings or accumulated other comprehensive income, depending on whether a derivative is effective as part of a hedged transaction. Gains and losses on derivative instruments reported in accumulated other comprehensive income are subsequently included in earnings in the periods in which earnings are affected by the hedged item. The Company does not use derivative instruments for speculative purposes.

The Company holds forward exchange contracts designed to hedge forecasted transactions denominated in foreign currencies and to minimize the impact of foreign currency fluctuations on the Company’s earnings and cash flows. Some of these contracts are designated as cash flow hedges. The Company will include in earnings amounts currently included in accumulated other comprehensive income upon recognition of cost of sales related to the underlying transaction. These contracts were not material to the Company's Condensed Consolidated Balance Sheets as of March 30,June 29, 2018 and December 31, 2017. The activity related to these contracts was not material to the Company's Condensed Consolidated Financial Statements for the three-month and six-month fiscal periods ended March 30,June 29, 2018 and March 31,June 30, 2017.

The decrease in contracts and other work in process (including certain general stock materials) was primarily attributable to the adoption of ASC 606.

Inventories include amounts associated with matters such as contract changes, negotiated settlements and claims for unanticipated contract costs. These amounts are as follows:

The following table sets forth the change in the carrying amount of goodwill for each reportable segment and for the Company:

Other intangible assets consisted of:
