The accompanying financial statements reflect the consolidated operations of Insulet and its subsidiaries (the “Company”). The unaudited consolidated financial statements in this Quarterly Report on Form 10-Q have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP” or "GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2019, or for any other subsequent interim period.

Use of Estimates in Preparation of Financial Statements
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the application of certain of its significant accounting policies that may materially affect the reported amounts of assets, liabilities, equity, revenue and expenses. Actual results may differ from those estimates.

Segment Reporting
Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis by the chief operating decision-maker ("CODM") in deciding how to allocate resources to an individual segment and in assessing performance of the segment. The Company has concluded its Chief Executive Officer ("CEO") is the CODM as the CEO is the ultimate decision maker for key operating decisions, determining the allocation of resources and assessing the financial performance of the Company. These decisions, allocations and assessments are performed by the CODM using consolidated financial information. The Company’s products are relatively consistent and manufacturing is centralized and consistent across product offerings. Based on these factors, key operating decisions and resource allocations are made by the CODM using consolidated financial data and as such the Company has concluded that it operates as one segment.


Shipping and Handling Costs
The Company does not typically charge its customers for shipping and handling costs associated with shipping its product to its customers unless non-standard shipping and handling services are requested. These shippingShipping and handling costs are included in general and administrative expenses and were $2.6$2.3 million and $1.01.4 million for the three months ended March 31,June 30, 2019 and 2018, respectively, and were $4.9 million and $2.5 million for the six months ended June 30, 2019 and 2018, respectively.


Reclassification of Prior Period Amounts
Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. Software license costs have been reallocated from general and administrative expenses to research and development and sales and marketing expenses based on license usage. These reclassifications have no effect on previously reported net income.


Recently Adopted Accounting Standards
Effective January 1, 2019, the Company adopted ASUAccounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (" (“ASU 2016-02"2016-02”). ASU 2016-02 and its related amendments (collectively referred to as ASC 842), which amends the guidance in former ASC Topic 840, Leases. The new standard increases transparency and comparability most significantly by requiring the recognition byrequires lessees ofto recognize right-of-use (“ROU”) assets and lease liabilities on the balance sheet for those leases classified as operating leases. The Company adopted ASC 842 on January 1, 2019 using the modified retrospective method, whereby the new guidance is applied prospectively as of the date of adoption and prior periods are not to be restated. The Company elected the package of practical expedients which permitsthat permit the Company to not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, and (3) any initial direct costs for any existing leases as of the effective date. The Company also excludes leases with an expected term of less than one year from the application of ASC 842. The adoption of the lease standard did not change the Company's previously reported consolidated statements of operations and did not result in a cumulative catch-up adjustment to opening equity. Adoption of the lease standard had a material impact on itsthe Company's consolidated balance sheet, (Note 13)which is disclosed in Note 11.
Effective January 1, 2019, the Company adopted ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"). ASU 2017-12 updates the current hedge accounting guidance with the objective of improving the financial reporting of hedging activities by better portraying the economic results of an entity's risk management activities in its financial statements. As the Company currently does not use derivative financial instruments, this guidance did not have any impact on the Company's financial statements upon adoption.
Effective January 1, 2019, the Company early adopted ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (" (“ASU 2018-15"2018-15”). ASU 2018-15 requires that entities capitalize certain costs to implement a cloud computing arrangement that is a service contract to be capitalized consistent with the rules applicable to internal useinternal-use software capitalization projects. The Company adopted this new guidance effective January 1, 2019, prospectively. Upon adoption, theThe Company defers

eligible costs related to the implementation of cloud computing arrangements within other current and non-current assets and amortizes thesesuch costs over the expected term ifof the hosting arrangement to the same income statement line as the associated cloud operating expenses. Adoption of this standard resulted in the Company capitalizing $1.3$0.7 million and $2.0 million of cloud computing implementation costs to the consolidated balance sheet for the period ending March 31, 2019.three and six months ended June 30, 2019, respectively.
Accounting Standards Issued and Not Yet Adopted
In January 2017, the Financial Accounting Standards Board ("FASB") issued ASU 2017-04, Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 simplifies the accounting for goodwill impairments by eliminating "Step 2" from the goodwill impairment test, which requires an entity to calculate the implied fair value of goodwill to measure a goodwill impairment charge, and alternatively, requires an entity to measure the impairment of goodwill assigned to a reporting unit as the amount by which the carrying value of the assets and liabilities of the reporting unit, including goodwill, exceeds the reporting unit's fair value. The guidance is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted for all entities. The Company is currently evaluating the impact of ASU 2017-04 but does not expect it to be material to the consolidated financial statements.
In August 2018, the FASB issued ASU 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13"). ASU 2018-13 modifies certain disclosure requirements related to fair value measurements primarily associated with Level 3 investments. The guidance is effective no later than January 1, 2020 for the Company and can be early-adopted prospectively in any interim period for certain disclosure requirements or retrospectively for others. The Company does not expect the adoption of this guidance to have a material impact on its fair value disclosures.
In June 2016, the FASB issued ASU 2016-13, Credit Losses(Topic 326) ("ASU 2016-13"). ASU 2016-13 requires that financial assets measured at amortized cost, such as trade receivables and contract assets, be presented net of expected credit losses, which may be estimated based on relevant information such as historical experience, current conditions, and future expectation for each pool of similar financial asset. The new guidance requires enhanced disclosures related to trade receivables and associated credit losses. The guidance is effective beginning January 1, 2020. The adoption of this guidance is expected to increase the level of disclosures related to the Company's trade receivables and is not expected to have a material impact on its consolidated financial statements.

Level 1 — quoted prices in active markets for identical assets or liabilities;
Level 2 — observable inputs other than quoted prices in active markets for identical assets or liabilities;
Level 3 — unobservable inputs infor which there is little or no market data, available, which require the reporting entityCompany to develop its own assumptions.

The Company recorded a debt discount of $120.7 million related to the 1.375% Notes resulting from the allocation of a portion of the proceeds to the fair value of the conversion feature reflecting a nonconvertible debt borrowing rate of 6.8% per annum. The debt discount was recorded as additional paid-in capital and is being amortized as non-cash interest expense over the seven year term of the 1.375% Notes. The Company also incurred debt issuance costs and other expenses related to the 1.375% Notes of approximately $10.9 million, of which $3.3 million was reclassified as a reduction to the value of the conversion feature allocated to equity. The remaining $7.6 million of debt issuance costs is presented as a reduction of debt in the consolidated balance sheet and is being amortized using the effective interest method as non-cash interest expense over the seven year term of the 1.375% Notes. As of March 31, 2019, the Company included $294.9 million on its balance sheet in long-term debt related to the 1.375% Notes.
1.25% Convertible Senior Notes
In September 2016, the Company issued and sold $345.0 million in principal amount of 1.25% Convertible Senior Notes, due September 15, 2021 (the "1.25% Notes"). The interest rate on the notes is 1.25% per annum, payable semi-annually in arrears in cash on March 15 and September 15 of each year. The 1.25% Notes are convertible into the Company’s common stock at an initial conversion rate of 17.1332 shares of common stock per $1,000 principal amount of the 1.25% Notes, which is equivalent to a conversion price of approximately $58.37 per share, subject to adjustment under certain circumstances. The 1.25% Notes will be convertible prior to the close of business on the business day immediately preceding June 15, 2021 only under certain circumstances and during certain periods, and will be convertible on or after June 15, 2021 until the close of business on the second scheduled trading day immediately preceding September 15, 2021, regardless of those circumstances.
The Company recorded a debt discount of $66.7 million related to the 1.25% Notes resulting from allocating a portion of the proceeds to the fair value of the conversion feature reflecting a nonconvertible debt borrowing rate of 5.8% per annum. The debt discount is being amortized as non-cash interest expense over the five year term of the 1.25% Notes. The Company incurred debt issuance costs and other expenses related to this offering of approximately $11.3 million, of which $2.2 million was reclassified as a reduction to the value of the amount allocated to equity. The remainder is presented as a reduction of debt in the consolidated balance sheet and is being amortized using the effective interest method as non-cash interest expense over the five year term of the 1.25% Notes. As of March 31, 2019, the Company has $304.8 million, net of discounts and issuance costs, on its balance sheet in long-term debt related to the 1.25% Notes.
2% Convertible Senior Notes
In June 2014, the Company issued and sold $201.3 million in principal amount of 2% Convertible Senior Notes due June 15, 2019 (the "2% Notes"). The 2% Notes were convertible into the Company’s common stock at an initial conversion rate of 21.5019 shares of common stock per $1,000 principal amount of the 2% Notes, which is equivalent to a conversion price of approximately $46.51 per share. In separately negotiated transactions, the Company repurchased $134.2 million in principal of the notes in September 2016 and $63.4 million in principal of the notes in November 2017. The Company elected to call the remaining notes in March 2018 and settled the outstanding principal and conversion feature of the notes for $6.7 million in cash in the second quarter of 2018. The Company allocated approximately $3.2 million of the settlement to the fair value of the equity component and $3.5 million to the debt component, which was consistent with the carrying value of the notes as of the settlement date, resulting in no gain or loss on extinguishment.


Note 6. Net Income (Loss) Per Share
Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period, excluding unvested restricted common shares. Diluted net income (loss) per share is computed using the weighted average number of common shares outstanding and, when dilutive, potential common share equivalents from outstanding stock options and restricted stock units (using the treasury-stock method), and potential common shares from the Company's convertible debt (using the if-converted method).

The following table below sets forth the components used in the computation of basic and diluted net income (loss) per share for the three and six months ended March 31, 2019.June 30, 2019. Because the Company reported a net loss for the three and six months ended March 31,June 30, 2018, all potential dilutive common shares have been excluded from the computation of the diluted net loss per share for the three and six months ended March 31,June 30, 2018, as the effect would have been anti-dilutive.

For the three and six months ended March 31,June 30, 2019, certain potential outstanding shares from stock options, restricted stock units and convertible debt were excluded from the computation of diluted net income per share because the effect of including these items was anti-dilutive. Additionally, certain performance-based restricted stock units were excluded from the computation of diluted net income per share because the underlying performance conditions for such restricted stock units had not yet been met as of these dates.met.

Product Warranty Costs
The Company generally provides a four-year warranty on its PDMsPersonal Diabetes Managers (“PDMs”) sold in the United States and Europe and a five-year warranty on its PDMs sold in Canada and may replace any OmnipodPods that doesdo not function in accordance with product specifications. The Company estimates its warranty at the time the product is shipped based on historical experience and the estimated cost to service the claims. Since the Company continues to introduce new products and versions, the anticipated performance of the product over the warranty period is also considered in estimating warranty reserves. Warranty expense is recorded in cost of goods sold onin the consolidated statementstatements of operations. Cost to service the claims reflects the current product cost. As these estimates are based on historical experience, and the Company continues to introduce new products and versions, the Company also considers the anticipated performance of the product over its warranty period in estimating warranty reserves.

Note 12.10. Commitments and Contingencies
Legal Proceedings
Between May 5, 2015 and June 16, 2015, three class action lawsuits were filed by shareholders in the U.S. District Court, for the District of Massachusetts, against the Company and certain individual current and former executives of the Company. Two suits subsequently were voluntarily dismissed. Arkansas Teacher Retirement System v. Insulet, et al., 1:15-cv-12345, (“ATRS”) alleged that the Company (and certain executives) committed violations of Sections 10(b) and 20(a) and Rule 10b-5 of the Securities Exchange Act of 1934 by making allegedly false and misleading statements about the Company’s business, operations, and prospects. On February 8, 2018, the parties executed a binding stipulation of settlement, under which all claims were released and a payment was made tointo an escrow account for the plaintiffs and the class they purport to represent. On August 6, 2018, the Court issued an order approving the settlement. The Company had previously accrued fees and expenses in connection with this matter for the amount of the final settlement liability that was not covered by insurance, the amount of which amount was not material to the Company's consolidated financial statements.


In addition, on April 26, 2017, a derivative action (Walker v. DeSisto, et al., 1:17-cv-10738) (“Walker”) was filed, and on October 13, 2017, a second derivative action (Carnazza v. DeSisto, et al., 1:17-cv-11977) (“Carnazza”) was filed, both on behalf of the Company, each by a shareholder in the U.S. District Court for the District of Massachusetts against the Company (as a nominal defendant) and certain individual current and former officers and directors of the Company. The allegations in the actions are substantially similar to those alleged in the securities class action. The actions seek, among other things, damages, disgorgement of certain types of compensation or profits, and attorneys’ fees and costs. On July 11, 2018, the parties executed a binding stipulation of settlement, under which all claims were released and a payment of attorneys’ fees and reimbursement of expenses will be paid to plaintiffs’ counsel, subject to the Court’s approval. On July 13, 2018, the plaintiffs filed a motion for preliminary approval of the settlement, which is pending. The Company expects that such fees and expenses payable to plaintiff's counsel will be covered by the Company's insurance.

The Company is, from time to time, involved in the normal course of business in various legal proceedings, including intellectual property, contract, employment and product liability suits. Although the Company is unable to quantify the exact financial impact of any of these matters, the Company believes that none of these currently pending matters will have an outcome material to its financial condition or business.
Fees To Former European Distributor
Following the expiration of its distributionan agreement with a former European distributor on June 30, 2018, the Company iswas required to pay to its former European Distributor a quarterly per-unit fee for Omnipod sales by the Company between July 1, 2018 and June 30, 2019 to certain customers of the former European Distributor.distributor for a one-year period through June 30, 2019.

The actualmethodology applicable for determining the total fee under under the distribution agreement is subject to an active arbitration proceeding in Switzerland. The final amount of the fee could vary significantly depending on the number of customers who count for purposes of calculating the fee under the terms of the distribution agreement, and the methodology applicable for determining this number under the agreement is subject to an active arbitration proceeding between the parties in Switzerland.agreement. The Company estimates that the final aggregate fee for the applicable twelve-month period could beis in the range of approximately $10$5 million to $55 million. As of March 31,June 30, 2019, the Company hashad recognized approximately $6.4$7.8 million for fees related to Omnipod devices sold to qualifying customers during the period from July 1, 2018 through March 31,June 30, 2019.


Note 13.11. Leases

In February 2016, the FASB issued guidance codifiedAs discussed in Note 2, ASC Topic 842 Leases, which amends the guidance in former ASC Topic 840, Leases. The new standard increases transparency and comparability most significantly by requiring the recognition byrequires lessees of right-of-useto recognize ROU assets and lease liabilities on the balance sheet for those leases classified as operating leases. The Company adopted ASC 842 on January 1, 2019. In accordance with the new lease standard,ASC 842, the Company determines if an arrangement is a lease at inception. Operating leases are included in otherlease ROU assets other current liabilities, and other long-term liabilities on our consolidated balance sheets. The Company does not have any significant finance leases. On January 1, 2019, upon the adoption of ASC 842, the Company recorded right-of-use assets of $8.8 million and an operating lease liability of $10.8 million on its consolidated balance sheet. The difference between the approximate value of the right-of-use assets and the approximate value of the lease obligations is attributable to a cease-use liability and deferred rent.
Operating lease right-of-use assets (ROU) and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, theThe Company uses its incremental borrowing rate in determining the present value of future payments.payments since most of its leases do not provide an implicit interest rate. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. On January 1, 2019, upon the adoption of ASC 842, the Company recorded ROU assets of $8.8 million and operating lease liabilities of $10.8 million on its consolidated balance sheet. The difference between the approximate value of the ROU assets and the approximate value of the lease obligations is primarily attributable to a former cease-use liability.
The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.
As of March 31, 2019, the Company's right-of-use assets obtained in exchange for lease obligations are $8.3 million included in other assets and total operating lease liabilities of $10.2 million included in other current liabilities and other long-term liabilities on the consolidated balance sheet.
The Company has an operating lease ofleases approximately 100,000 square feet of laboratory and office space in Billerica, Massachusetts. The lease expires in November 2022 and contains escalating payments over its life. Additionally, the Company leases approximately 29,000 square feet of warehousing space in Billerica, Massachusetts under a lease expiring in September 2019. The Company also leases international and certain other U.S. facilities. These operating leases expire at various dates through 2026, some of which may include options to extend the leases for up to 5 years, and some of which may include options to terminate the leases at certain times within the lease term. In the normal course of business, it is expected that these leases will be renewed.

The Company's total operating lease cost, was approximately $0.9 million and $0.8 million for the three months ended March 31, 2019 and March 31, 2018, respectively. Operating lease costwhich is recorded in general and administrative expenses in the consolidated statements of operations.

Executive Level Overview
We are primarily engaged in the development, manufacturing and sale of our proprietary Omnipod System (“Omnipod”), an innovative, discreet and easy-to-use continuous insulin delivery system for people with insulin-dependent diabetes. There are two primary types of insulin therapy practiced today: MDImultiple daily injection (“MDI”) therapy using syringes or insulin pens; and pump therapy using insulin pumps. Insulin pumps are used to perform continuous subcutaneous insulin infusion, or insulin pump therapy, and typically use a programmable device and an infusion set to administer insulin into the person’s body. Insulin pump therapy has been shown to provide people with insulin-dependent diabetes with numerous advantages relative to MDI therapy. We estimate that approximately one-third of the Type 1 diabetes population in the United States and less than one fifthone-fifth of the Type 1 diabetes population outside of the United States use insulin pump therapy. An even smaller portion of the Type 2 diabetes population in and outside of the United States who are insulin-dependent use insulin pump therapy. The Omnipod System features two discreet, easy-to-use devices: a small, lightweight, self-adhesive disposable tubeless Omnipod device which(“Pod”) that is worn on the body for approximately three days at a timetime; and its wireless companion, the handheld PDM.Personal Diabetes Manager (“PDM”). The Omnipod System which features two discreet, easy-to-use devices, communicates wirelessly, provides for virtually pain-free automated cannula insertion and eliminates the need for traditional MDI therapy or the use of traditional pump and tubing. We believe that the Omnipod System’sOmnipod’s unique proprietary design and features allow people with insulin-dependent diabetes to manage their diabetes with unprecedented freedom, comfort, convenience, and ease.

We began commercial sale ofhave been selling the Omnipod in the United States in 2005. Wesince 2005 and currently sell the Omnipod throughboth direct sales to customers, or through our distribution partners.partners and most recently through the pharmacy channel. The Omnipod is currently available in multiple countries in Europe, as well as in the United States, Canada and Israel. On July 1, 2018 we assumed all commercial activities (including, among other things, distribution, sales, marketing, training and support) for our Omnipod System across Europe following the expiration of our prior distributionan agreement with our former European Distributor on June 30, 2018.distributor.

In addition to the diabetes market space, we have partnered with pharmaceutical and biotechnology companies to tailor the Omnipod System technology platform for the delivery of subcutaneous drugs across other therapeutic areas. The majority of our drug delivery revenue currently consists of sales of podsPods to Amgen supplying the Neulasta® Onpro® kit, an innovative delivery system for Amgen’s white blood cell booster to help reduce the risk of infection during intense chemotherapy.

In June 2018, the FDA cleared our Omnipod DASHTM Insulin Management System (“Omnipod DASH”) for commercial distribution. The Omnipod Dash is our next-generation digital mobile Omnipod platform, featuring a secured Bluetooth enabled Pod and PDM with a touch screen color user interface supported by smartphone connectivity. We began a full market release of Omnipod DASH in the United States at the end of the first quarter of 2019.
We have substantially completedDuring the constructionsecond quarter of a2019, we began producing product from our new highly-automated manufacturing facility in Acton, Massachusetts, with planned production out of the facility beginning in the second quarter of 2019. The facility also serves as our global headquarters.Massachusetts. We expect that, following start up related activities, the new facility will allow us to lower our manufacturing costs, increase supply redundancy, add capacity closer to our largest customer base and support growth. From the purchase of this facility in late 2016 through March 31, 2019, capital expenditures for the construction of the Acton facility and related equipment purchases have been approximately $233 million. In 2019, we expect to invest additional capital in this facility to support our growth, funded by our existing cash and investments.


In January 2018, we announced that the Centers for Medicare & Medicaid Services ("CMS") has issued guidance clarifying that Medicare Part D Plan Sponsors may provide coverage for products such as the Omnipod System under the Medicare Part D (prescription drug) program. We have been securing coverage with Medicare Part D carriers to ensure beneficiaries living with diabetes have access to the Omnipod System. Securing Medicare Part D coverage also provides us with a direct pathway to increased Medicaid coverage at the state level, as many state-run Medicaid programs follow CMS prescription drug guidance to determine coverage. This allows access for lower-income individuals and families on Medicaid for whom Omnipod currently is not a covered option. In April 2018, we also significantly increased our market access when we secured in-network coverage of Omnipod with United Healthcare, the largest commercial payer in the United States.

In June 2018, the FDA provided clearance for the commercial distribution of our DASH TM System, which is our next-generation digital mobile Omnipod platform, featuring a secured Bluetooth enabled Pod and PDM with a touch screen color user interface supported by smartphone connectivity. We began a U.S. full market release of Omnipod DASH TM at the end of the first quarter of 2019.
FirstSecond Quarter 2019 Revenue Results:
Total revenue increased 43% year over year to $177.1 million and consisted of $159.6 millionthe following:
U.S. Omnipod revenue of $86.1$98.1 million,
an increase of 26%;
International Omnipod revenue of $56.9$62.7 million,
an increase of 120%; and
Drug Delivery revenue of $16.6$16.3 million,
a decrease of 8%.
Our long-term financial objective is to sustain profitable growth. We expect our efforts infor the remainder of 2019 to focus primarily on constructingproduct and commissioning our U.S. manufacturing facility, continuing to establish our European operations, launching new products, such as the DASH TM Omnipod System, continuing ourbusiness model innovation and product development, efforts, andincluding the continued roll out of Omnipod DASH, expanding penetration in our existing markets, working with Medicare, Medicaid and commercial payors and intermediaries to further expand access.access, and ramping up production at our new, highly automated U.S. manufacturing facility. Achieving these objectives is expected to require additional investments in certain initiatives and personnel, as well as enhancements to our supply chain operation capacity, efficiency and effectiveness.

Drug Delivery revenue decreased $1.4 million, or 8%, to $16.3 million over the same period in 2018 due to lower volume during the current period.
Total revenue for the six months ended June 30, 2019 increased $88.9 million, or 36%, to $336.7 million, compared with the six months ended June 30, 2018, due to strong growth in our International and U.S. Omnipod revenue. International Omnipod revenue increased $52.7 million, or 79%, to $119.6 million, due to the continued adoption of our product in existing international markets and more favorable pricing as a result of our shift to direct sales of the Omnipod in Europe. U.S. Omnipod revenue increased $35.9

For 2019, we expect strong Omnipod revenue growth driven by continued Omnipod expansion globally,penetration in our existing markets, partially offset by lower drug deliveryDrug Delivery revenue. Internationally, we expect higher revenues primarily due to increasing sales volume as a result of greater awareness and availability forof the Omnipod and the full year effect of more favorable pricing for the first half of the year as a result of our mid-2018 transition to direct commercial operationssales in Europe. In the U.S., we expect higher revenues primarily due to increasingan increase in sales volume as a result of expanded payor coverage, greater awareness and availability forof the Omnipod, the launch of Omnipod DASH and additional expansion of our U.S. sales force and customer support personnel to support our continued growth.force.
Cost of Revenue
Cost of revenue for the three months ended June 30, 2019 increased to $52.9 million, up $5.1$18.5 million, or 11%44%, in the first quarter of 2019to $60.7 million, compared towith the same period in 2018 dueand increased $23.6 million, or 26%, to increased$113.6 million for the six months ended June 30, 2019, compared with the same prior year period. These increases in cost of revenue were driven by higher sales volumes as well as start-up costs and inefficiencies related to our new U.S. manufacturing operations, partially offset by continued improvements in manufacturing and supply chain operations.
Gross Margin
Gross margin increased to 66.9%, up 550for the three months ended June 30, 2019 decreased 30 basis points to 65.7%, compared with the same period in 2018. The slight decrease in gross margin, which we expected, was primarily due to start-up costs and inefficiencies related to our new U.S. manufacturing operations.
Gross margin for the first quarter ofsix months ended June 30, 2019 increased 260 basis points to 66.3%, compared towith the same period in 2018. The increase in gross margin was primarily due primarily to (i) favorable pricing following the expiration of our former distributordistribution agreement in Europe and (ii) lower product cost as a result of continued improvements in manufacturing and supply chain operations. For 2019, weAs expected, these increases were partially offset by start-up costs and inefficiencies related to our new U.S. manufacturing operations. We expect full year 2019 gross marginsmargin to be relatively consistentlevel with 2018, as the benefits of continued improvements in manufacturing and supply chain operations and the full year effect of our mid-2018 assumption oftransition to direct commercial operations in Europe is expected to be offset by start-up costs and inefficiencies as we ramp up our new U.S. manufacturing operations.

Research and Development
Research and development expenses increased to $32.0 million, up $11.7 million, or 58%, for the three month periodmonths ended March 31,June 30, 2019 increased $13.5 million, or 72%, to $32.3 million, compared towith the same period in 2018.

These increases were primarily due to an increase in research and development expenses was primarily due to an increase in expenses related to our development projects, including Omnipod DASH and our Omnipod® HorizonTM automated insulin delivery system. Research and development expenses also increased due to engineering and operational costs, such as training and start up activities, associated with our newly constructed U.S. manufacturing facility, with planned production beginning in the second quarter of 2019. For 2019, wefacility. We expect overall research and development spending for the full year 2019 to increase as compared to 2018 primarily due to the development efforts for our ongoing projects.with 2018.

These increases were primarily attributable to investments to support our assumption in mid-2018 oftransition to direct commercial support forsales of Omnipod in Europe as well as the expansion of our U.S. sales force and customer support personnel.force. We expect sales and marketing expenses infor the full year 2019 to increase as compared towith 2018 due to additional expansion of our U.S. sales force and customer support personnel to support our continued growth and the full year effect of our mid-2018 assumption oftransition to direct commercial operationssales in Europe.

This increase was2018 and increased $10.1 million, or 23%, to $55.0 million for the six months ended June 30, 2019, compared with the same prior year period. These increases were primarily attributable to severance-related charges for certain executives as well as increased personnel-related costs and fees related to 2018 hires to support the establishment of our assumption in mid-2018 of direct support for Omnipodoperations in Europe. For 2019, weWe expect overall general and administrative expenses for 2019 to increase as compared towith 2018 as we continue to grow theour business and make investments in our operating structure to support continued growth as well as due to the full-year effect of our establishment oftransition to direct commercial operations in Europe in 2018.Europe.

Liquidity and Capital Resources
As of March 31,June 30, 2019, we had $129.3$119.9 million in cash and cash equivalents and $263.9$252.6 million of investments in marketable securities. We believe that our current liquidity will be sufficient to meet our projected operating, investing and debt service requirements for at least the next twelve months.
To lower our manufacturing costs, increase supply redundancy, add capacity closer to our largest customer base and support growth, we are constructingconstructed a highly-automated manufacturing facility in Acton, Massachusetts, with planned production out of the facility beginning infrom which we began producing product during the second quarter of 2019. This facility also serves as our global headquarters. As a result, capitalCapital expenditures have increasedin both 2018 and 2019 were above historic levels due to fundfunding the construction of the Acton facility and related equipment purchases. AsFrom the purchase of March 31,the facility in late 2016 through June 30, 2019, investments incapital expenditures for the construction of the Acton facility and related equipment purchases have been approximately $270 million.

Critical Accounting Policies and Estimates

OurThe preparation of our consolidated financial statements in conformity with U.S. GAAP requires management to use judgment in making estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities.
We believe that our accounting policies for revenue recognition, fair value measurements, accounts receivable and allowance for doubtful accounts, inventories, product warranty costs, convertible debt, commitments and contingencies and stock-based compensation are based on, the selection and application of generally accepted accounting principles, which require us to make estimatesamong other things, judgments and assumptions made by management that include inherent risks and uncertainties. There have been no significant changes to the above critical accounting policies or in the underlying accounting assumptions and estimates used in such policies from those disclosed in our annual consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K filed for the year ended December 31, 2018.

Accounting Standards Issued and Not Yet Adopted
In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 requires an entity to measure the impairment of goodwill assigned to a reporting unit as the amount by which the carrying value of the assets and liabilities of the reporting unit, including goodwill, exceeds the reporting unit's fair value. The guidance is effective for us beginning in the first quarter of 2020. Early adoption is permitted. We do not expect the adoption of this guidance to impact our consolidated financial statements.
In June 2016, the FASB issued ASU 2016-13, Credit Losses(Topic 326) (“ASU 2016-13”). ASU 2016-13 requires financial assets measured at amortized cost, such as trade receivables and contract assets, to be presented net of expected credit losses, which may be estimated based on relevant information such as historical experience, current conditions, and future expectation for each pool of similar financial assets. The new guidance also requires enhanced disclosures related to trade receivables and associated credit losses. The guidance is effective for us beginning in the first quarter of 2020. The adoption of this guidance is expected to increase the level of disclosures related to our trade receivables, but is not expected to have a material impact on our consolidated financial statements.

We have reviewed our policies and estimates to determine our critical accounting policies for the three months ended March 31, 2019. We have made no material changes to the critical accounting policies describedThe risk factors discussed in “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2018 and in this Quarterly Report could cause our results to differ materially from those expressed in forward-looking statements. In addition, there may be other risks and uncertainties that we are unable to predict at this time or that we currently do not expect to have a material adverse effect on our business. Actual results could differ materially from those projected in the forward-looking statements; accordingly, you should not rely upon forward-looking statements as predictions of future events.

required by law.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
We currently do not use derivative financial instruments in our investment portfolio and have no foreign exchange contracts. Our financial instruments consist of cash, cash equivalents, short-term and long-term investments, accounts receivable, accounts payable, accrued expenses, debt and long-term obligations. The primary objectives of our investment strategy are to preserve principal, maintain proper liquidity to meet operating needs and maximize yields. To minimize our exposure to an adverse shift in interest rates, we invest mainly in short-term investments and cash equivalents. We do not believe that a 10% change in interest rates would have a material impact on the fair value of our investment portfolio or our interest income.
As of March 31,June 30, 2019, we had outstanding convertible debt related to our Convertible Senior Notes recorded on our consolidated balance sheet of $599.6$607.4 million, net of unamortized discount and issuance costs totaling $147.9$140.1 million. Changes in the fair value of our outstanding debt, which could be impacted by changes in interest rates, are not recorded in these consolidated financial statements as the debt is accounted for at cost less unamortized discount and issuance costs. The fair value of the debt, which is disclosed in Note 5 to the consolidated financial statements, is also impacted by changes onin our stock price.
Our business is subject to risks, including, but not limited to: unique economic conditions, changes in political climate, differing tax structures, other regulations and restrictions, and foreign exchange rate volatility. A substantial portion of our operations are located in the United States, and the majority of our sales since inception have been made in United States dollars. Accordingly, we have assessed that we do not have any material net exposure to foreign currency exchange rate fluctuations at this time. However,States; however, as our business in markets outside of the United States continues to increase, we will be increasingly exposed to foreign currency exchange risk related to our foreign operations. Fluctuations in the rate of exchange between the United States dollar and foreign currencies, primarily the Euro, British Pound and Canadian Dollar, and the British Pound, could adversely affect our financial results, including our revenues, revenue growth rates, gross margins, income and losses as well as assets and liabilities.
We will continue to monitor and evaluate our internal processes relating to foreign currency exchange, including the potential use of hedging strategies.


Item 4. Controls and Procedures
Disclosure Controls and Procedures
Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31,June 30, 2019. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on

the evaluation of our disclosure controls and procedures as of March 31,June 30, 2019, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.
Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the three months ended March 31,June 30, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
