NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

1.Basis of Presentation
The condensed consolidated financial statements included herein have been prepared by Repligen Corporation (the “Company”, “Repligen” or “we”) in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), for Quarterly Reports on Form
10-Q
and Article 10 of RegulationS-X and do not include all of the information and footnote disclosures required by U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes thereto included in the Company’s Annual Report on Form
10-K
for the fiscal year ended December 31, 2017.

2018.

The preparation of financial statements in conformity with U.S. GAAP 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.

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Repligen Sweden AB, (“Repligen Sweden”), Repligen GmbH, Repligen Singapore Pte. Ltd., our former subsidiary, TangenX Technology Corporation (“TangenX,” acquired on December 14, 2016 and merged into the Company as of June 30, 2017) and Spectrum LifeSciences, LLC and its subsidiaries (“Spectrum,” acquired on August 1, 2017)., C Technologies, Inc. (“C Technologies,” acquired on May 31, 2019), and Repligen Singapore Pte. Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of only normal, recurring adjustments necessary for a fair presentation of the financial position, results of operations and cash flows. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the entire year.

Recent Accounting Standards Updates
We consider the applicability and impact of all Accounting Standards Updates on our consolidated financial statements. Updates not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. Recently issued Accounting Standards Updates which we feel may be applicable to us are as follows:
Recently Issued Accounting Pronouncements

Standard Updates – Not Yet Adopted

In May 2014,August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”)
2018-13,
“Fair Value Measurement (Topic 820): Disclosure 
Framework – Changes 
to the Disclosure Requirements for Fair Value Measurement.”
ASU
2018-13
includes amendments that aim to improve the effectiveness of fair value measurement disclosures. The amendments in this guidance modify the disclosure requirements on fair value measurements based on the concepts in FASB Concepts Statement,
“Conceptual Framework for Financial Reporting
Chapter 8: Notes to Financial Statements
,
including the consideration of costs and benefits. The amendments become effective for the Company in the year ending December 
31
,
2020
and early adoption is permitted. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements.
In August 2018, the FASB issued ASUNo. 2014-09, “Revenue from Contracts
2018-15,
“Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.”
ASU
2018-15
aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with Customersthe requirements for capitalizing implementation costs incurred to develop or obtain
internal-use
software (and hosting arrangements that include an
internal-use
software license). The guidance also requires the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. The guidance becomes effective for the Company in the year ending December 31, 2020 and early adoption is permitted. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements.
In November 2018, the FASB issued ASU
2018-18,
“Collaborative Arrangements (Topic 606),”(“ASC 606”) which supersedes808): Clarifying the revenue recognition requirements in Accounting Standards CodificationInteraction between Topic 605,Revenue Recognition,808 and creates a newTopic 606.”
ASU
2018-18
clarifies the interaction between Topic 808,
“Collaborative Arrangements,”
and Topic 606,
Revenue from Contracts with Customers,. Two adoption methods are permitted: retrospectively
by making targeted improvements to all prior reporting periods presented,GAAP for collaborative arrangements and providing guidance on whether certain transactions between collaborative arrangement participants should be accounted for with revenue under Topic 606. This includes improving comparability in the presentation of revenue for certain practical expedients permitted; or retrospectively with the cumulative effect of initially adopting the ASU recognized at the date of initial application. The adoption of this ASU included updates as provided under ASU2015-14, “Revenue from Contracts with Customers (Topic 606): Deferraltransactions between collaborative arrangement participants by allowing presentation of the Effective Date”; ASU2016-08, “Revenue from Contractsunits of account in collaborative arrangements that are within

the scope of Topic 606 together with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”; ASU2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing”; and ASU2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” The Company adopted the provisions of ASC 606 using the modified retrospective method effective January 1, 2018. See Note 3 for further discussion of the effects of this standard on the Company’s consolidated financial statements.

In January 2016, the FASB issued ASUNo. 2016-01, “Financial Instruments—Overall (Subtopic825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” This guidance changes how entities measure equity investments that do not result in consolidation and are notrevenue accounted for under the equity method. Entities will be required to measure these investments at fair value at the end of each reporting period and recognize changes in fair value in net income. A practicability exception will be availableTopic 606. The guidance becomes effective for equity investments that do not have readily determinable fair values; however, the exception requires the Company to consider relevant transactions that can be reasonably known to identify any observable price changes that would impactin the fair value. This guidance also changes certain disclosure requirementsyear ending December 31, 2020 and other aspects of current U.S. GAAP.early adoption is permitted. The Company adoptedis currently assessing the impact that this guidance in the first quarter of 2018. Because the Company does not hold any equity securities as of December 31, 2017 and June 30, 2018, adoption of this standard did notwill have any impact on its consolidated financial statements.

Recently Issued Accounting Standard Updates – Adopted During the Period
In February 2016, the FASB issued ASU No.
2016-02,
 “Leases (Topic 842).
ASU
2016-02,
along with subsequent ASUs issued to clarify certain provisions of ASU
2016-02
(collectively known as “ASC 842”), establishes a
right-of-use
(“ASU2016-02”ROU”). ASU2016-02 model that requires lesseesa lessee to recognizerecord aright-of-use ROU asset and a lease liability on the consolidated balance sheet for most leases. Extensiveall leases with terms longer than 12 months. Certain qualitative and quantitative disclosures are also required. The Company adopted ASU
2016-02
and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing contracts. The accounting applied by a lessor is largely unchanged from that applied under the current standard. The standard provides for certain practical expedients and must be adoptedrelated amendments on January 1, 2019 using either a modified retrospectivean optional transition approach or retrospectivelymethod allowed with the cumulative effectissuance of initially adoptingASU
2018-11,
“Leases – Targeted Improvements (Topic 842),”
in July 2018. ASU
2018-11
gives entities the ASU recognized atoption to not provide comparative period financial statements and instead apply the date of initial application. This ASU is effective for public entities for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company has commenced its review of leasestransition requirements as part of this standard, but has not finalized its assessment of the impacteffective date of the new standardstandard. Pursuant to additional guidance under ASC 842, the Company also elected the optional package of practical expedients, which allowed the Company to not reassess: (i) whether expired or existing contracts contain leases; (ii) lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. As a result, the consolidated balance sheet prior to January 1, 2019 was not restated, continues to be reported under ASC 840,
“Leases”,
which did not require the recognition of operating lease liabilities on itsthe consolidated financial statements.balance sheet, and is not comparative. Under ASC 842, all leases are required to be recorded on the balance sheet and are classified as either operating leases or finance leases, which is determined at the inception of the lease. The lease classification affects the expense recognition in the consolidated statements of comprehensive income (loss). The expense recognition for operating leases and finance leases under ASC 842 is substantially consistent with ASC 840. Therefore, there is no significant difference in our results of operations presented in our consolidated statements of comprehensive income (loss) for each period presented. The Company expects this new standardalso elected under the package of practical expedients, to havecombine lease and
non-lease
components and not to record leases with an initial term of 12 months or less on the consolidated balance sheet. The Company adopted ASC 842 using the optional transition method for all leases existing at January 1, 2019. The adoption had a materialsubstantial impact on our balance sheet. The most significant impact was the recognition of the operating lease ROU assets and lease liabilities for operating leases. Upon adoption, leases that were classified as operating leases under ASC 840 were classified as operating leases under ASC 842, and we recorded ROU assets of $17.0 million and lease liabilities of $21.0 million, before considering deferred taxes. The lease liability is based on the present value of the remaining minimum lease payments, determined under ASC 840, discounted using our incremental borrowing rate at the effective date January 1, 2019. The difference between the ROU assets and the lease liabilities is due to $4.0 million of unamortized lease incentives and deferred rent at the Company’s Marlborough and Waltham facilities as of December 31, 2018. There was no impact to our beginning retained earnings upon adoption of ASC 842. See Note 5,
“Leases,”
below for more information on the Company’s adoption of ASC 842.
2.Fair Value Measurements
In determining the fair value of its assets and liabilities, the Company uses various valuation approaches. The Company employs a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:
Level 1 –Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.
Level 2 –Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly.
Level 3 –Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement.
As of June 30, 2019 and December 31, 2018, cash and cash equivalents on the Company’s consolidated balance sheet.

sheets included $118.4 million and $126.6 million, respectively, in a money market account. These funds are valued on a recurring basis using Level 1 inputs.


In AugustMay 2016, the FASBCompany issued ASUNo. 2016-15, “Statement of Cash Flows (Topic 203): Classification of Certain Cash Receipts and Cash Payments”. ASUNo. 2016-15 addresses eight specific cash flow issues and clarifies their presentation and classification in the Statement of Cash Flows. This ASU is effective for fiscal years beginning after December 15, 2017 and is to be applied retrospectively with early adoption permitted. The Company has historically classified payments up to the$115.0 million aggregate principal amount of its contingent consideration liability recognized at the dateNotes due June 1, 2021 (the “2016 Notes”). Interest is payable semi-annually in arrears on June 1 and December 1 of its acquisition as financing activities, with additional payments classified as operating activities. Because the Company has classified its contingent consideration payments as required by this standard, the adoptioneach year, beginning on December 1, 2016. As of this standard did not have any impact on its consolidated financial statements when applied on a retrospective basis.

In October 2016, the FASB issued ASU2016-16, “Intra-Entity Transfers of Assets Other Than Inventory.” ASU2016-16 requires that the income tax consequences of an intra-entity asset transfer other than inventory are recognized at the time of the transfer. An entity will continue to recognize the income tax consequences of an intercompany transfer of inventory when the inventory is sold to a third party. The Company adopted this standard on a modified-retrospective basis on January 1, 2018. See Note 12 for a discussion of the impact of this ASU on the Company’s financial statements.

In November 2016, the FASB issued ASUNo. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires that the statement of cash flows explain the change during the period in the total cash, which is inclusive of cash and cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances on the statement of cash flows upon adoption of this standard. The Company adopted this standard on a retrospective basis on January 1, 2018. The adoption resulted in an increase to cash, cash equivalents and restricted cash of $450,000 in the statement of cash flows at December 31, 2016 and June 30, 2017. The Company did not hold any restricted cash at December 31, 2017 or June 30, 2018.

In January 2017, the FASB issued ASU No.2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”, which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted this standard as of January 1, 2018, and the adoption of ASU2017-01 did not have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASUNo. 2017-04, “Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” eliminating the requirement to calculate the implied fair value, essentially eliminating step two from the goodwill impairment test. ASUNo. 2017-04 requires goodwill impairment to be based upon the results of step one of the impairment test, which is defined as the excess of2019, the carrying value of the 2016 Notes was $105.7 million, net of unamortized discount, and the fair value of the 2016 Notes was $310.5 million. The fair value of the 2016 Notes is a reporting unit over itsLevel 1 valuation and was determined based on the most recent trade activity of the 2016 Notes as of June 30, 2019. The 2016 Notes are discussed in more detail in Note 8,

“Convertible Senior Notes”
to these consolidated financial statements.

3.Acquisition of C Technologies, Inc.
On April 25, 2019, Repligen agreed to reclassify to retained earnings tax effects related to items that have been stranded in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (the “Act”). For all entities, the guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Entities can choose whether to apply the amendments retrospectively to each period in which the effect of the Act is recognized or to apply the amendments in the period of adoption. The Company has not assessed the impact of the new standard on its consolidated financial statements, but does not expect this new standard to have a material impact on the Company’s consolidated financial statements.

The unaudited pro forma information for thesix-month period ended June 30, 2018 was calculated after applying the Company’s accounting policies and the impact of acquisition date fair value adjustments. The unaudited pro forma net income for thesix-month period ended June 30, 2018 was adjusted to exclude acquisition-related transaction costs, as these expenses would have been incurred in the prior year assuming the Spectrum Acquisition closed on January 1, 2016.

These pro forma condensed consolidated financial results include certain adjustments to reflect the pro formacombined results of operations of Repligen and C Technologies as if the acquisition had occurred as ofon January 1, 2016.2018 after giving effect to certain pro forma adjustments. The pro forma adjustments reflected herein include only those adjustments that are directly attributable to the C Technologies Acquisition, factually supportable and have a recurring impact. These pro forma adjustments include a $2.2 million and a $2.7 million net increase in amortization expense in 2019 and 2018, respectively, to record amortization expense for the $90.8 million of acquired identifiable intangible assets, adjustments to stock-based compensation of $0.3 million and $0.4 million, respectively, for equity compensation issued to C Technologies employees and the income tax effect of the adjustments made at the statutory tax rate of the United States (approximately 25%). In addition, acquisition-related transaction costs of $4.0 million and a $1.2 million purchase accounting adjustment to record inventory at fair value were excluded from pro forma net income in 2019.

3. Revenue Recognition

Adoption oflife science and biopharmaceutical industries. Under ASC Topic

606
,
Revenue from Contracts with Customers,

The Company adopted ASC 606 on January 1, 2018, using the modified retrospective method for all contracts not completed as of the date of adoption. For contracts that were modified before the effective date, the Company reflected the aggregate effect of all modifications when identifying performance obligations and allocating transaction price in accordance with the practical expedient in paragraph ASC606-10-65-1-(f)-4, which did not have a material effect on the cumulative impact of adopting ASC 606. Results for reporting periods beginning January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for the prior period. The impact to the Company’s consolidated financial statements as a result of applying ASC 606 was immaterial. Deferred

revenue resulting from contracts with customers is included in accrued expenses on the Company’s consolidated balance sheet.

Revenue Recognition

Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer (“transaction price”). 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 utilizing the expected value method or the most likely amount method, depending on the facts and circumstances relative to the contract. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. 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. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in paragraph606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of June 30, 2018.

Contracts with customers may contain multiple performance obligations. For such arrangements, the transaction price is allocated to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on 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 taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The Company recognizes product revenue under the terms of each customer agreement upon transfer of control to the customer, which occurs at a point in time.

When disaggregating revenue, the Company considered all of the economic factors that may affect its revenues. Because all of its revenues are from bioprocessing customers, there are no differences in the nature, timing and uncertainty of the Company’s revenues and cash flows from any of its product lines. However, given that the Company’s revenues are generated in different geographic regions, factors such as regulatory and geopolitical factors within those regions could impact the nature, timing and uncertainty of the Company’s revenues and cash flows. In addition, a significant portion of the Company’s revenues are generated from two customers; therefore, economic factors specific to these two customers could impact the nature, timing and uncertainty of the Company’s revenues and cash flows.

Filtration Products

The Company’s protein product line generatesfiltration products generate revenue through the sale of Protein A ligands and growth factors. Protein A ligands are an essential component of Protein A chromatography resins (media) used in the purification of virtually allmAb-based drugs on the market or in development. The Company manufactures multiple forms of Protein A ligands under long-term supply agreements with major life sciences companies, who in turn sell their Protein A chromatography media to end users (biopharmaceutical manufacturers). The Company also manufactures growth factors for sale under long-term supply agreements with certain life sciences companies as well as direct sales to its customers. Each protein product is considered distinct and therefore represents a separate performance obligation. Protein product revenue is generally recognized at a point in time upon transfer of control to the customer.

Filtration Products

The Company’s filtration product line generates revenue through the sale of KrosFlo

®
hollow fiber (“HF”) TFF membranes and modules, ProConnex
®
single-use flow path connectors, flat sheet TFF cassettes and hardware, and XCell™ XCell
alternating tangential flow (“ATF”) devices and related consumables.

The Company markets the KrosFlo line of HF cartridges and TFF systems and the ProConnex line of
single-use
flow path connectors which were acquired as part of the acquisition of Spectrum in August 2017.LifeSciences, LLC (the “Spectrum Acquisition”). These products are used in the filtration, isolation, purification and concentration of biologics and diagnostic products. Sales of large-scale systems generally include components and consumables as well as training and installation services at the request of the customer. Because the initial sale of components and consumables are necessary for the operation of the system, such items are combined with the systems as a single performance obligation. Training and installation services do not significantly modify or customize these systems and therefore represent a distinct performance obligation.

The Company’s other filtration product offerings are not highly interdependent of one another and are therefore considered distinct products that represent separate performance obligations. Revenue on these products is generally recognized at a point in time upon transfer of control to the customer. The Company invoices the customer for the installation and training services in an amount that directly corresponds with the value to the customer of the Company’s performance to date; therefore, revenue recognized is based on the amount billable to the customer in accordance with the practical expedient under ASC
606-10-55-18.

The Company also markets flat sheet TFF cassettes and hardware. TFF is a rapid and efficient method for separation and purification of biomolecules that is widely used in laboratory, process development and process scale applications in biopharmaceutical manufacturing. The Company’s
single-use Sius™
SIUS
TFF cassettes and hardware are not highly interdependent of one another and are therefore considered distinct products that represent separate performance obligations. SiusSIUS TFF product revenue is generally recognized at a point in time upon transfer of control to the customer.

The Company also markets the XCell™ XCell
ATF System, a technologically advanced filtration device used in upstream processes to continuously remove cellular metabolic waste products during the course of a fermentation run, freeing healthy cells to continue producing the biologic drug of interest. ATF Systems typically include a filtration system and consumables (i.e., tube devices, metal stands) as well as training and installation services at the request of the customer. The filtration system and consumables are considered distinct products and therefore represent separate performance obligations. First time purchasers of the systems typically purchase a controller that is shipped with the tube device(s) and metal stand(s). The controller is not considered distinct as it is a proprietary product that is highly interdependent with the filtration system; therefore, the controller is combined with the filtration system and accounted for as a single performance obligation. The training and installation services do not significantly modify or customize the ATF system and therefore represent a distinct performance obligation. ATF system product revenue related to the filtration system (including the controller if applicable) and consumables is generally recognized at a point in time upon transfer of control to the customer. ATF system service revenue related to training and installation services is generally recognized over time, as the customer simultaneously receives and consumes the benefits as the Company performs. The Company invoices the customer for the installation and training services in an amount that directly corresponds with the value to the customer of the Company’s performance to date; therefore, revenue recognized is based on the amount billable to the customer in accordance with the practical expedient under ASC
606-10-55-18.

Chromatography Products

The Company’s chromatography product line includesproducts include a number of products used in the downstream purification and quality control of biological drugs. The majority of chromatography revenue relates to the OPUS
pre-packed
chromatography column line and Protein A chromatography resins. OPUS columns typically consist of the outer hardware of the column with a resin as ordered by the customer packed inside of the column. OPUS columns may also be ordered without the packed resin. In either scenario, the OPUS column and resin are not interdependent of one another and are therefore considered distinct products that represent separate performance obligations. Chromatography product revenue is generally recognized at a point in time upon transfer of control to the customer.

Other


Protein Products

The Company’s other products include ELISA test kits used by quality control departments to detect and measureProtein product line generates revenue through the presencesale of leached Protein A and/orligands and growth factorfactors. Protein A ligands are an essential component of Protein A chromatography resins (media) used in the final product.purification of virtually all monoclonal antibody (“mAb”)-based drugs on the market or in development. The Company manufactures multiple forms of Protein A ligands under long-term supply agreements with major life sciences companies, who in turn sell their Protein A chromatography media to end users (biopharmaceutical manufacturers). The Company also manufactures growth factors for sale under long-term supply agreements with certain life sciences companies as well as direct sales to its customers. Each ELISA kitprotein product is considered distinct and therefore represents a separate performance obligation. Protein product revenue is generally recognized at a point in time upon transfer of control to the customer.
Process Analytics Products
On May 31, 2019, the Company consummated its acquisition of C Technologies and added a fourth franchise, Process Analytics, to our bioprocessing business. The Process Analytics product line generates revenue primarily through the sale of the SoloVPE and FlowVPE systems and consumables. These products will complement and support our existing Filtration, Chromatography and Proteins franchises as they allow end users to make in-line protein concentration measurements in filtration, chromatography and fill-finish applications, designed to allow for real-time process monitoring.
Other Products
The Company’s other products include operating room products sold to hospitals. Other product revenue is generally recognized at a point in time upon transfer of control to the customer.

Transaction Price Allocated to Future Performance Obligations

Remaining performance obligations represents the transaction price of contracts for which work has not been performed or has been partially performed. The Company’s future performance obligations relate primarily to the installation and training of certain of its systems sold to customers. These performance obligations are completed within one year of receipt of a purchase order from its customers. Accordingly, the Company has elected to not disclose the value of these unsatisfied performance obligations as provided under ASC
606-10-50-14.

A contract asset is created when the Company satisfies a performance obligation by transferring a promised good to the customer. Contract assets may represent conditional or unconditional rights to consideration. The right is conditional, and recorded as a contract asset, if the Company must first satisfy another performance obligation in the contract before it is entitled to payment from the customer. Contract assets are transferred to billed receivables once the right becomes unconditional. If the Company has the unconditional right to receive consideration from the customer, the contract asset is accounted for as a billed receivable and presented separately from other contract assets. A right is unconditional if nothing other than the passage of time is required before payment of that consideration is due.


When consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract, a contract liability is recorded. Contract liabilities are recognized as revenue after control of the products or services is transferred to the customer and all revenue recognition criteria have been met.

Costs to Obtain or Fulfill a Customer Contract

The Company’s sales commission structure is based on achieving revenue targets. The commissions are driven by revenue derived from customer purchase orders which are short term in nature.

Applying the practical expedient in paragraph340-40-25-4, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs are included in selling, general, and administrative expenses. When shipping and handling costs are incurred after a customer obtains control of the products, the Company accounts for these as costs to fulfill the promise and not as a separate performance obligation.

5.Leases
On January 1, 2019, the Company adopted ASC 842 using the optional transition method which allows entities to initially apply the lease accounting transition requirements at the adoption date and recognize a cumulative effect adjustment to the opening balance sheet of retained earnings in the period of adoption without restating comparative prior periods presented. The Company recorded operating lease right of use assets of $17.0 million and operating lease liabilities of $21.0 million as of January 1, 2019. The difference between the right of use assets and the lease liabilities was due to $4.0 million of unamortized lease incentives and deferred rent at the Company’s Waltham and Marlborough facilities as of December 31, 2018.
The Company is a lessee under leases of manufacturing facilities, office spaces, machinery, certain office equipment, vehicles and information technology equipment. A majority of the Company’s leases are operating leases with remaining lease terms between three months and 11 years. Finance leases are immaterial to our consolidated financial statements. The Company determines if an arrangement qualifies as a lease and what type of lease it is at inception. The Company elected the package of practical expedients permitted under the transition guidance within the new lease standard, which among other things, allowed it to continue to account for existing leases based on the historical lease classification. The Company also elected the practical expedients to combine lease and
non-lease
components and to exclude right of use assets and lease liabilities for leases with an initial term of 12 months or less from the balance sheet.
Some of the lease agreements the Company enters into include Company options to either extend and/or early terminate the lease, the costs of which are included in our operating lease liabilities to the extent that such options are reasonably certain of being exercised. Leases with renewal options allow the Company to extend the lease term typically between 1 and 5 years per option, some of its leases have multiple options to extend. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain that the Company would exercise such options.
As of June 30, 2019, operating lease right of use assets 
were $
19.5
million and operating lease liabilities were 
$
23.5

During the second quarter of 2019 we added leases related to our acquisition of C Technologies on May 31, 2019 which resulted in an increase of right of use assets and lease liabilities of $3.8 million as of June 30, 2019. Amounts related to financing leases were immaterial. The maturity of the Company’s operating lease liabilities as of June 30, 2019 are as follows (amounts in thousands):

6.Goodwill and Other Intangible Assets
Goodwill
Goodwill represents the difference between the purchase price and the estimated fair value of identifiable assets acquired and liabilities assumed. Goodwill acquired in a business combination and determined to have an indefinite useful life is not amortized, but instead is tested for impairment at least annually in accordance with ASC Topic 260, “Earnings Per Share,” which establishes standards for computing and presenting earnings per share. Basic earnings per share is computed by dividing net income available to common shareholders by350. The following table represents the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares and dilutive common share equivalents then outstanding. Potential common share equivalents consist of restricted stock awards and the incremental common shares issuable upon the exercise of stock options. Under the treasury stock method, unexercised“in-the-money” stock options and warrants are assumed to be exercised at the beginning of the period or at issuance, if later. The assumed proceeds are then used to purchase common shares at the average market price during the period. Share-based payment awards that entitle their holders to receivenon-forfeitable dividends before vesting are considered participating securities and are consideredchange in the calculationcarrying value of basic and diluted earnings per share. There were no such participating securities outstanding duringgoodwill for the three- andsix-month periodssix months ended June 30, 2018 and 2017.

During each of the Company’s common stock at a weighted average exercise price of$26.72per share and716,996restricted stock units. Forfourth quarters of 2018, 2017 and 2016, we completed our annual impairment assessments and concluded that goodwill was not impaired in any of those years. The Company has not identified any “triggering” events which indicate an impairment of goodwill in the three- andsix-month periodsthree months ended June 30, 2018,551,012and615,930options to purchase shares of the Company’s common stock, respectively, were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares, and were therefore anti-dilutive.

At June 30, 2017, there were outstanding options to purchase 803,532 shares of the Company’s common stock at a weighted average exercise price of $20.16 per share and 393,338 restricted stock units. For the three- andsix-month periods ended June 30, 2017, 187,072 and 222,001 options to purchase shares of the Company’s common stock, respectively, were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares, and were therefore anti-dilutive.

As provided by the terms of the indenture underlying the Company’s 2.125% Convertible Senior Notes due 2021 (the “Notes”), the Company has a choice to settle the conversion obligation2019.

Other Intangible Assets
Intangible assets, except for the Notes in cash, shares or any combination of the two. The Company currently intends to settle the par value of the Notes in cash and any excess conversion premium in shares. The Company applies the provisions of ASC 260,Earnings Per Share, Subsection10-45-44, to determine the diluted weighted average shares outstanding as it relates to the conversion spread on its convertible notes. Accordingly, the par value of the Notes will not be included in the calculation of diluted income per share, but the dilutive effect of the conversion premium will be considered in the calculation of diluted net income per share using the treasury stock method. The dilutive impact of the Company’s convertible notes is based on the difference between the Company’s current period average stock price and the conversion price of the convertible notes, provided there is a premium. Pursuant to this accounting standard, there is no dilution from the accreted principal of the Notes as of June 30, 2018 and June 30, 2017.

6. Inventories

Inventories relate to the Company’s bioprocessing business. The Company values inventory at cost or, if lower, market value, using thefirst-in,first-out method. The Company reviews its inventories at least quarterly and records a provision for excess and obsolete inventory based on its estimates of expected sales volume, production capacity and expiration dates of raw materials,work-in-process and finished products. Expected sales volumes are determined based on supply forecasts provided by key customers for the next 3 to 12 months. The Company writes down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value, and inventory in excess of expected requirements to cost of product revenue. Manufacturing of bioprocessing finished goods is done to order and tested for quality specifications prior to shipment.

A change in the estimated timing or amount of demand for the Company’s products could result in additional provisions for excess inventory quantities on hand. Any significant unanticipated changes in demand or unexpected quality failures could have a significant impact on the value of inventory and reported operating results. During all periods presented in the accompanying financial statements, there have been no material adjustments related to a revised estimate of inventory valuations.

8. Intangible Assets

Intangible assetsATF tradename, are amortized over their useful lives using the straight-lineestimated economic benefit method, as applicable, and the amortization expense is recorded within selling, general and administrative expense in the Company’s statements of comprehensive income.

income (loss). The Company reviews its indefinite-lived intangible assets not subject to amortization, including the ATF tradename, to determine if adverse conditions exist or a change in circumstances exists that would indicate an impairment. Intangible assets and their related useful lives are reviewed at least annually to determine if any adverse conditions exist that would indicate the carrying value of these assets may not be recoverable. More frequent impairment assessments are conducted if certain conditions exist, including a change in the competitive landscape, any internal decisions to pursue new or different technology strategies, a loss of a significant customer, or a significant change in the marketplace, including changes in the prices paid for our products or changes in the size of the market for our products. An impairment results if the carrying value of the asset exceeds the estimated fair value of the asset. If the estimate of an intangible asset’s remaining useful life is changed, the remaining carrying amount of the intangible asset is amortized prospectively over the revised remaining useful life. The Company continues to believe that its intangible assets are recoverable at June 30, 2018.

were approximately $111.1 million.
The 2016 Notes bear interest at the rate
of 2.125% per annum, payable

in arrears on June 1 and December 1 of each year, beginning

The 2016 Notes will mature on
June 1, 2021
,
unless earlier repurchased, redeemed or converted in accordance with their terms. Prior to March 1, 2021, the 2016 Notes will be convertible at the option of holders of the 2016 Notes only upon satisfaction of certain conditions and during certain periods, and thereafter, the notes2016 Notes will be convertible at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, holders of the 2016 Notes will receive shares of the Company’s common stock, cash or a combination thereof, at the Company’s election. It is the Company’s current intent and policy to settle all conversions through combination settlement, which involves satisfying the principal amount outstanding with cash and any note conversion value over the principal amount in shares of the Company’s common stock.

On July 19, 2019, the Company exchanged, with a limited number of holders in privately negotiated transactions, $

92.0
million aggregate principal amount of the existing 2016 Notes for a combination of cash and shares of the Company’s common stock. For more information on this transaction, see Note 16,
“Subsequent Events – Exchange and Redemption of 2016 Notes,”
below.
2016 Notes with a par value of $17,000 were submitted for conversion in the first quarter of 2019, and the conversion was settled in the second quarter. 2016 Notes with a par value of $11,000 were submitted for conversion in the fourth quarter of 2017, and this conversion was settled in the first quarter of 2018. The conversionconversions resulted in the issuance of a nominal amountnominal-amount of shares of the Company’s common stock, and the Company recorded a loss of $1,000 on the conversion of these Notes.

notes of approximately $3,000 in the second quarter of 2019 and $1,000 in the first quarter of 2018 in their consolidated statements of comprehensive 

income (loss).
During the second quarter of 2018,2019, the closing price of the Company’s common stock exceededcontinued to exceed 130% of the conversion price of the 2016 Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the 2016 Notes are convertible at the option of the holders of the 2016 Notes during the third quarter of 2018. The2019, the quarter immediately following the quarter when the conditions were met, as stated in the terms of the 2016 Notes. These terms have been met each quarter since the second quarter of 2018 and, expecting to continue meeting these terms, the Company reclassifiedcontinues to classify the carrying value of the 2016 Notes from long term liabilities toas a current liabilitiesliability on the Company’s consolidated balance sheet as of June 30, 2018.2019. As of June 30, 2018,2019, the
if-converted
value of the 2016 Notes exceeded the aggregate principal amount by approximately $63.8$195.5 million. As mentioned above, $17,000 par value notes were submitted for conversion at the end of the date of this filing, no Notes have been converted by the holders of such Notes in the thirdfirst quarter of 2018.2019 and settled during the second quarter. In the event the closing price conditions are met in the third quarter of 20182019 or a future fiscal quarter, the 2016 Notes will be convertible at a holder’s option during the immediately following fiscal quarter.

The conversion rate for the 2016 Notes will initially be 31.1813 shares of the Company’s common stock per $1,000 principal amount of 2016 Notes, which is equivalent to an initial conversion price of approximately $32.07 per common share, and is subject to adjustment under the terms of the 2016 Notes. Holders of the 2016 Notes may require the Company to repurchase their 2016 Notes upon the occurrence of a fundamental change prior to maturity for cash at a repurchase price equal to 100% of the principal amount of the 2016 Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

The Company will not have the right to redeem the Notes prior

Subsequent to June 5, 2019, but maythe Company has had the ability to redeem the 2016 Notes, at its option, in whole or in part, on any business day on or after June 5, 2019 and prior to the maturity date if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides written notice of redemption. The redemption price will be equal to 100% of the principal amount of the principal amount of2016 Notes to be redeemed plus accrued and unpaid interest to, but excluding, the redemption date.

The 2016 Notes contain customary terms and events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving the Company) occurs and is continuing, the holders of at least 25% in aggregate principal amount of the outstanding 2016 Notes may declare 100% of the principal of, and any accrued and unpaid interest on, all of the 2016 Notes to be due and payable. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company, 100% of the principal of and accrued and unpaid interest, if any, on all of the 2016 Notes will become due and payable automatically. Notwithstanding the foregoing, the 2016 Notes provide that, to the extent the Company elects and for up to 270 days, the sole remedy for an event of default relating to certain failures by the Company to comply with certain reporting covenants consist exclusively of the right to receive additional interest on the 2016 Notes. The Company is not aware of any events of default, current events or market conditions that would allow holders to call or convert the 2016 Notes as of June 30, 2018.

2019.

The cash conversion feature of the 2016 Notes required bifurcation from the 2016 Notes and was initially accounted for as an equity instrument classified to stockholders’ equity, as the conversion feature was determined to be clearly and closely related to the Company’s stock. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies in the same industry and asset base and with similar maturity, the Company estimated the implied interest rate, assuming no conversion option. Assumptions used in the estimate represent what market participants would use in pricing the liability component, including market interest rates, credit standing, and yield curves, all of which are defined as Level 2 observable inputs. The estimated implied interest rate was applied to the 2016 Notes, which resulted in a fair value of the liability component of $96,289,000$96.3 million upon issuance, calculated as the present value of implied future payments based on the $115 million aggregate principal amount. The equity component of the 2016 Notes was recognized as a debt discount, recorded in additional
paid-in
capital, and represents the difference

between the aggregate principal of the 2016 Notes and the fair value of the 2016 Notes without conversion option on their issuance date. The debt discount is amortized to interest expense using the effective interest method over five years, or the life of the 2016 Notes. The Company assesses the equity classification of the cash conversion feature quarterly, and it is not re-measured as long as it continues to meet the conditions for equity classification.

which includesincluded the interest on the 2016 Notes, amortization of the debt discount and debt issuance costs. As of June 30, 2018,2019, the carrying value of the 2016 Notes was approximately $101.3
$115.0 million
 and the fair value of the principal was approximately $178.8
$310.5 million. 
The fair value of the 2016 Notes was determined based on the most recent trade activity of the 2016 Notes as of June 30, 2018.

In May 2019, the Company entered into a fifth amendment of the existing lease to expand the rented space from approximately 76,000 square feet to approximately 108,000 square feet at 41 Seyon Street, Waltham, Massachusetts, the Company’s corporate headquarters and primary location for all manufacturing, research and development, sales and marketing and administrative operations. The Company expects to be completely moved into the new space by the beginning of 2020. Under the terms of the fifth amendment lease, the initial fixed rental rate is $29.00 per square foot, per annum, of the additional square footage (approximately 32,000 square feet) and will increase at a rate of $1.00 per annum.
Licensing and Research Agreements
The Company licenses certain technologies that are, or may be, incorporated into its technology under several agreements and also has entered into several clinical research agreements which require the Company to fund certain research projects. Generally, the license agreements require the Company to pay annual maintenance fees and royalties on product sales once a product has been established using the technologies. Research and development expenses associated with license agreements were immaterial amounts for the three months ended June 30, 2019 and 2018.
In September 2018, we entered into a collaboration agreement with Sartorius Stedim Biotech, a leading international supplier for the biopharmaceutical industry, to integrate XCell
ATF cell retention control technology into Sartorius’s BIOSTAT
®
STR large-scale,
single-use
bioreactors to create novel perfusion-enabled bioreactors. As a result of this collaboration,
end-users
will stand to benefit from a single control system for 50L to 2,000L bioreactors used in perfusion cell culture applications. The single interface is designed to control cell growth, fluid management and cell retention in continuous and intensified bioprocessing and, ultimately, simplify the development and manufacture of biotechnological drugs under current good manufacturing practices.
In June 2018, we secured an agreement with Navigo for the exclusive
co-development
of multiple affinity ligands for which Repligen holds commercialization rights. We are manufacturing and have agreed to supply the first of these ligands,
NGL-Impact
A, exclusively to Purolite Life Sciences (“Purolite”), who will pair our high-performance ligand with Purolite’s agarose jetting base bead technology used in their Jetted A50 Protein A resin product. We also signed a long-term supply agreement with Purolite for
NGL-Impact
A and other potential additional affinity ligands that may advance from our Navigo collaboration. The Navigo and Purolite agreements are supportive of our strategy to secure and reinforce our proteins business. We made payments to Navigo of $2.4 million during the year ended December 31, 2018 in connection with this program, which were recorded to research and development expenses in our consolidated statements of comprehensive income (loss).

“Intra-Entity Transfers of the Act enacted in December 2017. The effective tax rate for thesix-month period ended June 30, 2018 was higher than the U.S. statutory tax rate of 21% due to state tax effects and the impact of the GILTI tax. For the three- andsix-month periods ended June 30, 2017, the effective tax rate was lower than the U.S. statutory tax rate of 34% primarily due to the sale of intellectual property from Repligen Corporation to Repligen Sweden AB. The Company utilized certain of its U.S. deferred tax assets as a result of this sale and reduced its valuation allowance on these deferred tax assets by approximately $9,200,000 in the second quarter of 2017. The Company recorded a tax benefit of $5,625,000 on the Company’s consolidated statement of operations as a result of the sale of the intellectual property.

The Company adopted the provisions of this ASU in the first quarter of 2018. The adoption resulted in a decrease of $5,609,000$5.7 million to other assets, a decrease of $4,932,000$5.0 million to deferred tax liabilities and a decrease of $677,000$0.7 million to accumulated deficit at January 1, 2018.

In December 2017, the complexities involved in accounting for the enactment of the Act, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which allowsto address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to recordcomplete the accounting for certain income tax effects of H.R.1. The Company recognized the provisional tax impacts related to deemed repatriated earnings and the revaluation of deferred tax assets and liabilities and included these amounts in its consolidated financial statements for the year ended December 31, 2017. During 2018, final adjustments noted below were made to the provisional amounts recorded during a measurement period not to extend beyond one year of the enactment date. Under the SAB 118 guidance,2017, and the Company has determined that althoughcompleted its accounting for the effect of certain provisionsvarious tax impacts of the Act is incomplete, it is able to make reasonable estimates for certain effects of tax reform and therefore have recorded provisional amounts.

The Act lowered the Company’s U.S. statutory federal tax rate from 35% to 21% effective January 1, 2018. The Company recorded a tax benefit of $12,812,000$12.8 million in the year ended December 31, 2017 for the reduction in its US deferred tax assets and liabilities resulting from the rate change.

The Companyaccounting for this item is subjectcomplete and no adjustments were made to a territorial tax system under the Act, in which the Company is required to provide for tax on GILTI earned by certain foreign subsidiaries. Additionally, the Company is required to make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred as a period expense. As of June 30, 2018, the Company is still evaluating the effects of the GILTI provisions as guidance and interpretations continue to emerge. Therefore, the Company has not determined its accounting policy on the GILTI provisions. However, the standard requires that the Company reflects the impact of the GILTI provisions as a period expense until the accounting policy is finalized. Therefore, the Company has included the provisional estimate of GILTI related to current-year operations in its estimated annual effective tax rate only and will be updating the impact and accounting policy as the analysis related to the GILTI provisions is completed.

13. Fair Value Measurement

In determining

13.
Earnings Per Share
The Company reports earnings per share in accordance with ASC 260,
“Earnings Per Share,”
which establishes standards for computing and presenting earnings per share. Basic earnings per share is computed by dividing net income available to common shareholders by the fairweighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares and dilutive common share equivalents then outstanding. Potential common share equivalents consist of restricted stock awards and the incremental common shares issuable upon the exercise of stock options. Under the treasury stock method, unexercised
“in-the-
24
money”
stock options and warrants are assumed to be exercised at the beginning of the period or at issuance, if later. The assumed proceeds are then used to purchase common shares at the average market price during the period. Share-based payment awards that entitle their holders to receive
non-forfeitable
dividends before vesting are considered participating securities and are considered in the calculation of basic and diluted earnings per share. There were no such participating securities outstanding during the three-month periods ended June 30, 2019 and 2018.
Basic and diluted weighted average shares outstanding were as follows:

At June 30, 2019, there were outstanding options to purchase 985,266 shares of the Company’s common stock at a weighted average exercise price of $30.16 per share and 766,986 shares of common stock issuable upon the vesting of RSUs. For the three and six months ended June 30, 2019, 119,026 and 
180,160
 options to purchase shares of the Company’s common stock, respectively, were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares and were therefore anti-dilutive.
At June 30, 2018, there were outstanding options to purchase 1,058,834 shares of the Company’s common stock at a weighted average exercise price of $26.72 per share and 716,996 shares issuable upon the vesting of RSUs. For the three- and
six-
month periods ended June 30, 2018, 551,012 and 615,930 options to purchase shares of the Company’s common stock, respectively, were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares and were therefore anti-dilutive.
As provided by the terms of the indenture underlying the 2016 Notes, the Company has a choice to settle the conversion obligation for the 2016 Notes in cash, shares or any combination of the two. The Company currently intends to settle the par value of its assetsthe 2016 Notes in cash and liabilities, the Company uses various valuation approaches.any excess conversion premium in shares. The Company employs a hierarchy for inputs used in measuring fairapplies the provisions of ASC 260,
“Earnings Per Share”,
Subsection 10-45-44, to determine the diluted weighted average shares outstanding as it relates to the conversion spread on the 2016 Notes. Accordingly, the par value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available2016 Notes is not included in the circumstances. The fair value hierarchycalculation of diluted income per share, but the dilutive effect of the conversion premium is broken down into three levels based on the source of inputs as follows:

Level 1 –Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access
Level 2 –Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly
Level 3 –Valuations based on inputs that are unobservable and significant to the overall fair value measurement

The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservableconsidered in the market,calculation of diluted net income per share using the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levelstreasury stock method. The dilutive impact of the fair value hierarchy.

The Company’s fixed income investments have historically comprised of obligations of U.S. government agencies and corporate marketable securities. These investments have been initially valued at the transactioncurrent period average stock price and subsequently valued, at the end of each reporting period, utilizing third party pricing services or other market observable data. The pricing services utilize industry standard valuation models, including both income and market based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. At least annually, the Company validates applicable prices provided by third party pricing services by reviewing their pricing methods and matrices, obtaining market values from other pricing sources, analyzing pricing data in certain instances and confirming that the relevant markets are active.

As of June 30, 2018 and December 31, 2017, the Company had no assets or liabilities for which fair value measurement is either required or has been elected to be applied.

The Notes are discussed in more detail in Note 10, “Convertible Senior Notes.

Overview

Repligen and its subsidiaries, collectively doing business as Repligen Corporation (“Repligen”, “we”, “our”, or “the Company”) is a leading provider of advanced bioprocessing technologytechnologies and solutions used in the process of manufacturing biologic drugs. Our products are made to substantially increase biopharmaceutical manufacturing efficiencies and flexibility. As the global biologics market continues to experience strong growth and expansion, our customers – primarily large biopharmaceutical companies and contract manufacturing organizations – face critical production cost, capacity, quality and time pressures that our products are made to address. Our commitment to bioprocessing is helping to set new standards for the way our customers manufacture biologic drugs – including monoclonal antibodies (“mAb”), recombinant proteins, vaccines and gene therapies. We are dedicated to inspiring“inspiring advances in bioprocessingbioprocessing” as a trusted partner in the production of biologic drugs that improve human health worldwide.

disposable columns that replace the Company was focused onuse of traditional and more permanent glass columns used in downstream purification processes. By designing OPUS to be a technologically advanced and flexible option for the purification of biologics from process development through clinical-scale and some commercial manufacturing, Repligen has become a leader in PPC columns.
Our filtration products offer a number of advantages to manufacturers of biologic drugs at volumes that span from pilot studies to clinical and commercial-scale production. XCell ATF
systems are used primarily in upstream perfusion, or continuous manufacturing, processes to increase cell concentration and significantly improve biologic product yield from a bioreactor. To address increasing industry demand for
“plug-and-play”
technology, we developed and launched in 2016
single-use
formats of the original stainless steel XCell ATF device. In December 2016, we acquired TangenX Technology Corporation (“TangenX”), balancing our upstream XCell ATF offering with a downstream portfolio of flat-sheet filters and cassettes used in biologic drug development,purification and formulation processes. The TangenX portfolio includes the
single-use
SIUS
TFF brand, providing customers with clinical trial costs supported by bioprocessinga high-performance,
low-cost
alternative to reusable TFF products. In August 2017, we completed our acquisition of Spectrum LifeSciences, LLC (“Spectrum”). Our Spectrum filtration brands include the KrosFlo
®
family of products, ProConnex
®
disposable flow-path products, TFF systems and others. The Spectrum Acquisition significantly strengthened our Filtration product sales. At that timeline and diversifies our bioprocessing business was largely represented by salesend markets beyond mAbs to include vaccine, recombinant protein and gene therapies.
We are a leading OEM manufacturer and supplier of Protein A ligands which we sell through long term original equipment manufacturer (“OEM”) supply agreements. Our 2011 acquisition of Novozymes Biopharma Sweden AB further expanded our proteins product portfolio and provided the impetus to set a new direction for the company. Bymid-2012, we permanently discontinued and have since divested all drug development programs. We retained our proteins OEM business and, through internal innovation and strategic acquisitions, we have built chromatography and filtration product offerings that we sell directly to biologics manufacturers. We continue to seek out strategic opportunities to strengthen and expand our bioprocessing business.

We currently operate as one bioprocessing business, with a comprehensive suite of products to serve both upstream and downstream processes in biologic drug manufacturing. Building on over 35 years of industry expertise, we have developed a broad and diversified product portfolio that reflects our commitment to build abest-in-class bioprocessing technology company with a world-class direct sales and commercial organization.

Our Protein products are represented by ourlife sciences companies. Protein A affinity ligands and cell culture growth factor products. In addition to long-standing OEM supply agreements with GE Healthcare, MilliporeSigma and Purolite Life Sciences for these products, in June 2018 we securedare an agreement with Navigo Proteins GmbH for the exclusive co-developmentessential “binding” component of multiple affinity ligands for which Repligen holds commercialization rights. We are manufacturing and have agreed to supply the first of these ligands, NGL-Impact A, exclusively to Purolite Life Sciences, who will pair our high performance ligand with their agarose jetting base bead technology used in Purolite’s Jetted A50 Protein A resin.

Ourdirect-to customer Chromatography product line includes a number of productschromatography resins used in the downstream purification and quality control of biologicalvirtually all mAb based drugs on the market or in development that our customers sell to end users, including a broad range of OPUS®pre-packed chromatography columns, chromatography resins and ELISA test kits.

Ourdirect-to-customer Filtration product line includes our XCell™ ATF system for use in upstream process intensification, our Sius™ TFF cassettesbiopharmaceutical manufacturers, for use in downstream purification of mAbs. We also manufacture and formulation processes,sell growth factor products used to supplement cell culture media in order to increase cell growth and productivity in a bioreactor.

C Technologies Acquisition
On April 25, 2019, the Company entered into a Stock Purchase Agreement (“Purchase Agreement”) with C Technologies, Inc. (“C Technologies”), a New Jersey corporation, and Craig Harrison, an individual and sole stockholder of C Technologies. The deal was consummated on May 31, 2019, the acquisition date (the “C Technologies Acquisition”).
C Technologies sells instruments, consumables and accessories that are designed to allow bioprocessing technicians to measure the protein concentration of a liquid sample using C Technologies’ Slope Spectroscopy method, which eliminates the need for manual sample dilution. C Technologies’ lead product, the SoloVPE instrument platform, was launched in our XCell ATF systems2008 for

Product revenues
Since 2016, we have been increasingly focused on selling our products directly to customers in the pharmaceutical industry and to our contract manufacturers. Direct sales represent approximately 71% of our product revenue in the second quarter of 2019 and 72% of our product sales for the first half of 2019. We expect that direct sales will continue to account for an increasing percentage of our product revenues. Sales of our bioprocessing products increased 47.2%can be impacted by the timing of large-scale production orders and 46.9%the regulatory approvals for such antibodies, which may result in significant quarterly fluctuations.
Revenue from our chromatography products includes the three-sale of our OPUS and six-month periodsOPUS PD chromatography columns, chromatography resins and ELISA test kits. Revenue from our filtration products includes the sale of our XCell ATF Systems and consumables, KrosFlo filtration products and SIUS filtration products. Revenue from protein products includes the sale of our Protein A ligands and cell culture growth factors. Revenue from our Process Analytics products includes the sale of our SoloVPE and FlowVPE systems and consumables. Other revenue primarily consists of revenue from the sale of our operating room products to hospitals as well as freight revenue.
During the three and six months ended June 30, 2018,2019, product revenue increased by $22.9 million, or 48% and $38.7 million, or 41.9%, respectively, as compared to the correspondingsame periods of 2018. The increase in the prior year. This increase was primarilyboth periods is due to the continued adoption of our products by our key bioprocessing customers, particularly our chromatography and for the three- andsix-month periods of 2018, the addition of revenues following the Spectrum Acquisition.filtration products. Sales of our bioprocessing products are impacted by the timing of orders, development efforts at our customers or
end-users
and regulatory approvals for biologics that incorporate our products, which may result in significant quarterly fluctuations. Such quarterly fluctuations are expected, but they may not be predictive of future revenue or otherwise indicate a trend.

Additionally, there was a $2.2 million increase in revenue for the three and six months ended June 30, 2019, as compared to the same periods of 2018 due to revenues generated by C Technologies.


Royalty revenues
Royalty revenues in the three and six months ended June 30, 2019 and 2018 relate to royalties received from a third-party systems manufacturer associated with our OPUS PD chromatography columns. Royalty revenues are variable and are dependent on sales generated by our partner.
Costs and operating expenses

Total costs and operating expenses for the three-three andsix-month periods six months ended June 30, 20182019 and 20172018 were comprised of the following:

Gross margins were 56.6% and 56.2% in the prior year. Thisthree and six months ended June 30, 2019, respectively. The gross margin for the three and six months ended June 30, 2019 includes $1.2 million of amortization on an inventory
step-up
recorded in purchase accounting related to C Technologies Acquisition. Excluding this
step-up
amortization, gross margins for the three and six months ended June 30, 2019 were 58.2% and 57.1%, respectively. The increase in gross margins is primarily duea result of the increase in revenue mentioned above offset by an increase in manufacturing headcount subsequent to the increased product revenues noted above.June 30, 2018. Gross margins may fluctuate in the third and fourthfuture quarters of 2018 based on expected production volume and product mix.

Research and development expenses
Research and development expenses increasedare related to bioprocessing products, which include personnel, supplies and other research expenses. Due to the small size of the Company and the fact that these various programs share personnel and fixed costs, we do not track all of our expenses or allocate any fixed costs by 210.8%program, and 151.7% intherefore, have not provided historical costs incurred by project. In addition to the three-legacy product research and six-month periodsdevelopment, the current
single-use
XCell ATF project incurs expenses related to product development, sterilization, validation testing, and other research related expenses.
Research and development expenses decreased 9.5% and 2.4% during the three and six months ended June 30, 2018,2019, respectively, compared to the correspondingsame periods in the prior year. This increaseof 2018. The decrease is driven byprimarily due to $2.3 million of investments made induring the second quarter of 2018 to expand our proteins product offeringsoffering through our development agreement with Navigo Proteins GmbH. Additionally,GmbH compared to only $0.5 million in the three and six months ended June 30, 2019, respectively. This decrease was partially offset by an increase in research and development headcount subsequent to June 30, 2018 and an increase in stock-based compensation expense resulting from the increase is related to productin headcount and share price period over period.
We expect our research and development activities acquired as partexpenses for the rest of the Spectrum Acquisition and increased activity on our various bioprocessingyear to increase slightly in order to support new product development projects.

Selling, general and administrative expenses increased 48.3%
Selling, general and 59.5% inadministrative (“SG&A”) expenses include the three-costs associated with selling our commercial products and six-month periodscosts required to support our marketing efforts, including legal, accounting, patent, shareholder services, amortization of intangible assets and other administrative functions.
During the three and six months ended June 30, 2018,2019, SG&A costs increased by $7.1 million, or 42.9%, and $10.2 million, or 31.4%, respectively, as compared to the correspondingsame periods in the prior year. Thisof 2018. The increase is due to selling and administrative activities incurred following the Spectrum Acquisition, as well as the continued buildout of our administrative infrastructure to support future growth and continued expansion of our customer-facing activities to drive sales of our bioprocessing products.

Investment income

Investment incomeproducts and to the continued buildout of our administrative infrastructure, primarily through increased headcount, to support expected future growth. In addition, transaction fees related to the C Technologies Acquisition of $3.5 million and $4.0 million for the three-three andsix-month periods six months ended June 30, 2019, respectively, were included in SG&A,


for which there were no comparable costs for the same periods of 2018. Sales commissions were higher in 2019 due to the increase in revenue and stock compensation expense increased during both periods in 2019 as compared to 2018 due to the increase in headcount and 2017 was as follows:

Investment income
Investment income includes income earned on invested cash balances. The increase in investment income inof $0.5 million and $1.0 million for the three-three andsix-month periods six months ended June 30, 20182019, respectively, as compared to the corresponding prior yearsame periods isof 2018 was attributable to higher average invested cash balances and higher interest rates on such invested cash balances.

We expect investment income to vary based on changes in the amount of funds invested and fluctuation of interest rates.

Interest expense

Interest expense primarily includes interest related to our issuance of 2.125% Convertible Senior Notes due 2021 (the “2016 Notes”) in May 2016. Interest expense increased $0.1 million for the three-three andsix-month periods six months ended June 30, 2019, as compared to the same periods of 2018, and 2017 was as follows:

The effective tax rate was 18.7%15.8% and 22.1%19.8% for the three-three andsix-month periods six months ended June 30, 2018,2019, respectively, and is based upon the estimated income for the year and the composition of the income in different jurisdictions. The effective tax rate for the three-month period ended June 30, 2018 was lower than the U.S. statutory rate of 21% due to R&D credit activity and windfall benefits on stock option exercises and restricted stock vestings, partially offset by state tax effects and the impact of the Global IntangibleLow-Taxed Income (“GILTI”) tax enacted as part of the Tax Cuts and Jobs Act (the “Act”) enacted inending December 2017. The effective tax rate for thesix-month period ended June 30, 2018 was higher than the U.S. statutory tax rate of 21% due to state tax effects and the impact of the GILTI tax.

The effective tax rate was lower than the U.S. statutory tax rate of 34%21% due primarily due to a benefitwindfall benefits on stock option exercises and the vesting of approximately $5,625,000 related to the reduction of the Company’s valuation allowance on its deferred tax assets resulting from the sale of certain intellectual property from Repligen Corporation to Repligen Sweden AB in the second quarter of 2017.

Non-GAAP
Financial Measures

We provide
non-GAAP
adjusted income from operations; adjusted net income; and adjusted EBITDA as supplemental measures to GAAP measures regarding our operating performance. These financial measures exclude the items detailed below and, therefore, have not been calculated in accordance with GAAP. A detailed explanation and a reconciliation of each
non-GAAP
financial measure to its most comparable GAAP financial measure is provided below.

We include this financial information because we believe these measures provide a more accurate comparison of our financial results between periods and more accurately reflect how management reviews its financial results. We excluded the impact of certain acquisition-related items because we believe that the resulting charges do not accurately reflect the performance of our ongoing operations for the period in which such charges are incurred.

Liquidity and Capital Resources

We have financed our operations primarily through revenues derived from product sales, research grants, proceeds and royalties from license arrangements, sales of equity securities andthe issuance of convertible debt.the 2016 Notes in May 2016 and our 2019 Notes (defined below) in July 2019 and the issuance of common stock in our July 2019, May 2019 and July 2017 public offerings. Our revenue for the foreseeable future will primarily be limited to our bioprocessing product revenue.

At June 30, 2018,2019, we had cash and cash equivalents of $175,611,000$208.9 million compared to cash, and cash equivalents of $173,759,000$193.8 million at December 31, 2017.

2018.

We acquired C Technologies on May 31, 2019 for $239.9 million in cash and shares of our common stock. The C Technologies Acquisition was funded through payment of approximately $195.0 million in cash and 779,221 unregistered shares of the Company’s common stock totaling $53.9 million.
During the second quarter of 2019, the closing price of the Company’s common stock exceeded 130% of the conversion price of the 2016 Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the 2016 Notes are convertible at the option of the holders of the 2016 Notes during the third quarter of 2019. The 2016 Notes have a face value of $115.0 million and a carrying value of $105.7 million and are classified as current liabilities on the Company’s consolidated balance sheet as of June 30, 2019.

On May 3, 2019, the Company completed a public offering in which 3,144,531 shares of its common stock, which includes the underwriters’ exercise in full of an option to purchase up to an additional 410,156 shares, were sold to the public at a price of $64.00 per share. The total proceeds received by the Company from this offering, net of underwriting discounts and commissions, totaled approximately $190.2 million. Proceeds from this public offering were partially used to fund the C Technologies Acquisition on May 31, 2019.
On July 19, 2019, the Company completed a public offering in which 1,587,000 shares of its common stock, which includes the underwriters’ exercise in full of an option to purchase an additional 207,000 shares, were sold to the public at a price of $87.00 per share for $130.7 million in net proceeds to the Company, after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company (the “Stock Offering”).
On July 19, 2019, the Company issued $287.5 million aggregate principal amount of 0.375% Convertible Senior Notes due 2024 (“2019 Notes”), which includes the underwriters’ exercise in full of an option to purchase an additional $37.5 million aggregate principal amount of 2019 Notes (the “Notes Offering” and, together with the Stock Offering, the “Offerings”). The net proceeds of the Notes Offering, after deducting underwriting discounts and commissions and other estimated offering expenses payable by the Company, were $278.4 million. See Note 16,
“Subsequent Events – Public Offering of Convertible Senior Notes,”
included in this report
for more information on this transaction. We intend to use the net proceeds from the Offerings for working capital and other general corporate purposes, including up to $115 million to finance the redemption, or a portion of the consideration due in connection with an exchange or purchase of, the 2016 Notes and the remainder for working capital and other general corporate purposes, including to fund possible acquisitions of, or investments in, complementary businesses, products, services and technologies. It is the Company’s policy and intent to settle the face value of the 2019 Notes in cash and any excess conversion premium in shares of our common stock.
Substantially concurrent with the closing of the Notes Offerings, the Company completed privately negotiated transactions with certain holders of the 2016 Notes to exchange an aggregate of $92.0 million aggregate principal amount of the 2016 Notes for a combination of cash and shares of the Company’s common stock (the “Note Exchanges”). The Company used $92.3 million in cash and issued 1,850,155 shares of common stock, to settle the Note Exchanges.
Contemporaneously with the closing of the Offerings, the Company issued a notice of redemption in respect of the 2016 Notes, which provides that, on September 23, 2019, the Company will redeem all 2016 Notes that have not been converted, repurchased or exchanged prior to such date at a redemption price in cash equal to 100% of the principal amount thereof plus accrued and unpaid interest.

above, including the C Technologies Acquisition.

Our future capital requirements will depend on many factors, including the following:

the expansion of our bioprocessing business;

our identification and execution of strategic acquisitions or business combinations;

the ability to sustain sales and profits of our bioprocessing products;

market acceptance of our new products;

our ability to acquire additional bioprocessing products;

our identification and execution of strategic acquisitions or business combinations;
the resources required to successfully integrate our recently acquired businesses and recognize expected synergies;

the scope of and progress made in our research and development activities;

the extent of any share repurchase activity;

and

the election of any Note holders to convert their Notes during an eligible period; and

the success of any proposed financing efforts.

Absent acquisitions of additional businesses, products, product candidates or intellectual property, we believe our current cash balances are adequate to meet our cash needs for at least twelvethe next 24 months from the date of this filing. We expect operating expenses for the rest of the year to increase as we integrate Spectrum into our business, continue to developexpand our bioprocessing business. We expect to incur continued spending related to the development and expandexpansion of our bioprocessing product lines and expandexpansion of our commercial capabilities for the foreseeable future. Our future capital requirements may include, but are not limited to, purchases of property, plant and equipment, the acquisition of additional bioprocessing products and technologies to complement our existing manufacturing capabilities, and continued investment in our intellectual property portfolio and future repayment of convertible debt.

In order to acquire such assets, we may need to seek additional financing to fund these investments.

Contractual Obligations and Commitments

In February 2018, we entered into an agreement to lease 63,761 square feet of office and manufacturing space in Marlborough, Massachusetts from U.S. REIF 111 Locke Drive Massachusetts, LLC (the “Premises”).

The lease commences during the second quarter of 2018 (the “Commencement Date”) and shall continue for a period of 126 consecutive months, unless earlier terminated in accordance with the terms of the lease (the “Lease Term”). Under the lease, the Company has the option to extend the Lease Term for two additional five-year periods.

Fixed rent with respect to 40,000 square feet of the Premises only shall commence on the Commencement Date, and rent for the full 63,761 square feet of the Premises shall begin 19 months following the Commencement Date.

Net Operating Loss Carryforwards
At December 31, 2018, we had utilized our remaining $19.5 million of net operating loss carryforwards. We had business tax credits carryforwards of $2.9 million available to reduce future federal income taxes, if any. The business tax credits carryforwards will continue to expire at various dates through December 2038. Net operating loss carryforwards and available tax credits are subject to review and possible adjustment by the Internal Revenue Service, state and foreign jurisdictions and may be limited in the event of certain changes in the ownership interest of significant stockholders.
Effects of Inflation
Our assets are primarily monetary, consisting of cash, cash equivalents and marketable securities. Because of their liquidity, these assets are not directly affected by inflation. Since we intend to retain and continue to use our equipment, furniture and fixtures and leasehold improvements, we believe that the incremental inflation related to replacement costs of such items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase our level of expenses and the rate at which we use our resources.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk

Rate Risk

We have historically invested fundsheld investments in commercial paper, U.S. Government and agency securities as well as corporate bonds and other debt securities. As a result, we have been exposed to potential loss from market risks that may occur as a result of changes in interest rates, changes in credit quality of the issuer or otherwise. As of June 30, 2018, weWe do not have any such investments; however, we may seek to invest fundsinvestments as of June 30, 2019. As a result, a hypothetical 100 basis point increase in similar investment vehiclesinterest ratees would have no effect on our cash position as of June 30, 2019.
We generally place our marketable security investments in the future,high quality credit instruments, as specified in our investment policy guidelines. OurWe believe that the conservative nature of our investments mitigates our interest rate exposure, and our investment policy limits the amount of our credit exposure to any one issue, issuer (with the exception of U.S. government and agency securities)obligations) and type of instrument.

We do not expect any material loss from our marketable security investments and therefore believe that our potential interest rate exposure is limited.


Foreign exchange risk

Exchange Risk

The reporting currency of the Company is U.S. dollars, and the functional currency of each of our foreign subsidiaries is its respective local currency. Our foreign currency exposures include the Swedish kronor, Euro, British pound, Chinese yuan, Japanese yen, Singapore dollar, South Korean won and Indian rupee; of these, the primary foreign currency exposures are the Swedish kronor, Euro and British pound. Exchange gains or losses resulting from the translation between the transactional currency and the functional currency are included in net income. Fluctuations in exchange rates may adversely affect our results of operations, financial position and cash flows. We currently do not seek to hedge this exposure to fluctuations in exchange rates.

ITEM 4. CONTROLS AND PROCEDURES

ITEM 4.CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Company’s management, with the participation of the principal executive officer and the principal financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules
13a-15(e)
or
15d-15(e)
under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as of the end of the period covered by this report. Based on such evaluation, the principal executive officer and principal financial officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, on a timely basis, and is accumulated and communicated to the Company’s management, including the Company’s principal executive officer and the Company’s principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control

We acquired Spectrum LifeSciences, LLC (“Spectrum”) in August 2017.C Technologies on May 31, 2019. The financial results of SpectrumC Technologies are included in our unaudited consolidated financial statements as of June 30, 2019 and for the three-quarter then ended. The C Technologies business represented approximately $2.2 million of revenue andsix-month periods ($1.5) million of net loss, respectively, for the quarter ended June 30, 2018. Spectrum represented approximately $36,331,000 of our total assets as of June 30, 2018 and $24,031,000 of revenues for thesix-month period ended June 30, 2018.2019. As this acquisition occurred duringin the second halfquarter of 2017,2019, the scope of our assessment of our internal control over financial reporting does not include Spectrum.C Technologies. This exclusion is in accordance with the SEC’sSecurities and Exchange Commission’s general guidance that an assessment of a recently acquired business may be omitted from our scope in the year of acquisition. We are actively reviewing and updating Spectrum’s internal control policies and procedures, and management will include Spectrum in its report on internal control over financial reporting as of and for the year ended December 31, 2018.

Effective January 1, 2018, we adopted the provisions of ASC 606, “Revenue from Contracts with Customers.” As part of the adoption of this standard, we reviewed our control procedures and have modified certain of our processes to ensure compliance with the new standard.

Other than the foregoing, there have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Securities Exchange Act Rule
13a-15
or Rule
15d-15
that occurred in the three months ended June 30, 20182019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
