1.    Summary of Significant Accounting Policies

Basis of Presentation

We prepared the consolidated financial statements included herein pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations. We believe that the disclosures are adequate to make the information presented not misleading. We recommend that these consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in our latest annual report on Form 10-K for the fiscal year ended December 31, 2017,2018, filed with the SEC on February 28, 2018.March 1, 2019.

In our opinion, these unaudited consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary to present fairly our financial position as of March 31, 2018,2019, our results of operations for the three months ended March 31, 2018,2019, and our cash flows for the three months ended March 31, 2018.2019.  The results of operations for the interim period are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2018.2019.

Basis of Consolidation

The consolidated financial statements include all the assets, liabilities, revenues, expenses and cash flows of Stamps.com Inc. and the entities in which we have a 100% voting and/or economic control, which includes Stamps.com Inc., Auctane LLC (ShipStation), Interapptive, Inc. (ShipWorks), MetaPack Limited (MetaPack), PhotoStamps Inc., PSI Systems, Inc. (Endicia), and ShippingEasy Group, Inc. (ShippingEasy) and PhotoStamps Inc.. In July 2016,August 2018, we completed our acquisition of 100% of the outstanding shares of ShippingEasy.MetaPack. Please see Note 2 - “Acquisitions” in our Notes to Consolidated Financial Statements for further description. References in this Report to "we" "us" "our" or "Company" are references to Stamps.com Inc. and its subsidiaries.
Intercompany accounts and transactions between consolidated entities have been eliminated in consolidation.
Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements. SignificantThere are significant estimates and judgments inherent in the preparation of the consolidated financial statements include estimatesincluding the fair value of loss contingenciesassets and liabilities for allocation of the realizabilitypurchase price of deferred income taxes.companies acquired.
Prior Period Reclassifications
Certain amounts in prior periods have been reclassified to conform with current period presentation.
Business Combinations

The acquisition method of accounting is used for business combinations. The results of operations of acquired businesses are included in our consolidated financial statements prospectively from the date of acquisition. The fair value of purchase consideration is allocated to the assets acquired and liabilities assumed from the acquired entity and is generally based on their fair value at the acquisition date. The excess of the fair value of purchase consideration over the fair value of the assets acquired and liabilities assumed is recorded as goodwill. Historically, the primary items that have generated goodwill include anticipated synergies between the acquired business and the Company and the acquired assembled workforce, neither of which qualifies for recognition as an intangible asset. Acquisition-related expenses are recognized in our consolidated financial statements as incurred.

Contingencies and Litigation

In the ordinary course of business, we are subject to various routine litigation matters as a claimant and a defendant. We record any amounts recovered in these matters when received. We establish loss provisions for claims against us when the loss is both probable and can be reasonably estimated.  If either or both of the criteria are not met, we assess whether there is at least a reasonable possibility that a loss, or additional losses, may have been incurred. If there is a reasonable possibility that a loss or additional loss may have been incurred for such proceedings, we disclose the estimate of the amount of loss or possible range of loss, or disclose that an estimate of loss cannot be made, as applicable.

Deferred Revenue

Our deferred revenue relates mainly to service revenue, which generally arises due to the timing of payment versus the provision of services for certain customers billed in advance. Approximately $4.2 million of revenue recognized in the three months ended March 31, 2019 was included in the deferred revenue balance at December 31, 2018. Approximately $2.1 million of revenue recognized in the three months ended March 31, 2018 was included in the deferred revenue balance at December 31, 2017.

Fair Value of Financial Instruments

Carrying amounts of certain of our financial instruments, including cash and cash equivalents, accounts receivable and accounts payable, approximate fair value due to their short maturities. The Company’s outstanding debt held by third-party financial institutions is carried at cost, adjusted for debt issuance costs. The Company’s debt is not publicly traded and the carrying amount typically approximates fair value for debt that accrues interest at a variable rate for companies with similar financial characteristics as the Company, which are considered Level 2 fair value inputs as defined in Note 8 in our Consolidated Financial Statements.
Foreign Currency Translation

The functional currency of the Company’s major foreign subsidiaries is generally the local currency. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded in accumulated other comprehensive income as a component of stockholders’ equity. Foreign currency transaction gains and losses are included in foreign currency exchange gain (loss), net. All assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the average exchange rate during the period.
Goodwill and Indefinite-Lived Intangible Assets

Goodwill represents the excess of the fair value of consideration given over the fair value of the tangible assets, identifiable intangible assets and liabilities assumed in a business combination. We are required to test goodwill for impairment annually and whenever events or circumstances indicate the fair value of a reporting unit may be below its carrying value. A reporting unit is the operating segment or a business that is one level below that operating segment. Reporting units are aggregated as a single reporting unit if they have similar economic characteristics. We aggregated our reporting units into a single reporting unit because we determined they have similar economic characteristics.

Goodwill is reviewed for impairment annually on October 1 utilizing either a qualitative assessment or a two-step process. We have an option to make a qualitative assessment of a reporting unit's goodwill for impairment. If we choose to perform a qualitative assessment and determine the fair value more likely than not exceeds the carrying value, no further evaluation is necessary. When we perform the two-step process, the first step requires us to compare the fair value of ourthe reporting unit, which we primarily determine using an income approach based on the present value of discounted cash flows, to the respective carrying value, which includes goodwill. If the fair value of ourthe reporting unit exceeds its carrying value, the goodwill is not considered impaired. If the carrying value is higher than the fair value, there is an indication that impairment may exist and the second step is required. In step two, the implied fair value of goodwill is calculated as the excess of the fair value of ourthe reporting unit over the fair values assigned to its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of ourthe reporting unit's goodwill, the difference is recognized as an impairment loss. As of March 31, 2018,2019, we are not aware of any indicators of impairment that would require an impairment analysis other than our annual goodwill impairment analysis.
Indefinite-lived intangible assets are reviewed for impairment annually on October 1.1 and whenever events or circumstances indicate that the fair value of an indefinite-lived intangible asset may be below its carrying value. In assessing other intangible assets not subject to amortization for impairment, the Company also has the option to perform a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of such an intangible asset is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of such an intangible asset is less than its carrying amount, then the Company is not required to perform any additional tests for assessing those intangible assets for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, then it is required to perform a quantitative impairment test that involves a comparison of the estimated fair value of the intangible asset with its carrying value. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. As of March 31, 2018,2019, we are not aware of any indicators of impairment that would require an impairment analysis other than our annual indefinite-lived intangible assets impairment analysis.

Long-Lived Assets and Finite-Lived Intangible Assets
Long-lived assets including intangible assets with finite useful lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
We account for property and equipment at cost less accumulated depreciation and amortization. We compute depreciation using the straight-line method over the estimated useful life of the asset, generally three to five years for furniture, fixtures, and equipment and ten to forty years for building and building improvements. Leasehold improvements are capitalized and amortized over the shorter of the useful life of the asset or the remaining term of the lease. We have a policy of capitalizing expenditures that materially increase assets' useful lives and charging ordinary maintenance and repairs to operations as incurred. When property or equipment is disposed of, the cost and related accumulated depreciation and amortization are removed, and any gain or loss is included in income from operations.

Income Taxes

We are subject to income taxes in the US and Foreign jurisdictions. We provide for income taxes at the current and future enacted tax rate and consistent with the laws applicable in each jurisdiction. We account for income taxes in accordance with Financial Accounting Standards Board (FASB) ASC Topic No. 740, Income Taxes (Income Taxes), which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax basis of recorded assets and liabilities. Income Taxes also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the net deferred tax assets will not be realized. We record a valuation allowance to reduce our gross deferred tax assets to the amount that is more likely than not (a likelihood of more than 50 percent) to be realized.  In order for us to realize our deferred tax assets, we must be able to generate sufficient taxable income. We evaluate the appropriateness of our deferred tax assets and related valuation allowance in accordance with Income Taxes based on all available positive and negative evidence.

Leases

On January 1, 2019, we adopted a new lease accounting standard (ASC Topic No. 842, Leases) (Leases) that sets out the principles for the recognition, measurement, presentation, and disclosure of leases for both lessees and lessors. For information regarding the impact of adoption, see “Summary of Significant Accounting Policies - Accounting Guidance Adopted in 2019.”

Under Leases, we determine if an arrangement is a lease at inception. Right-of-use (ROU) assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. For this purpose, we consider only payments that are fixed and determinable at the time of commencement. As most of our leases do not provide an implicit rate, the interest rate used to determine the present value of future lease payments is an estimated incremental borrowing rate. Many of our leases include one or more options to renew. These options are factored into the determination of the lease term and lease payments when their exercise is considered to be reasonably certain.

Our lease agreements generally contain lease and non-lease components. Non-lease components primarily include payments for maintenance and utilities. We elected the practical expedient to combine fixed payments for non-lease components with our lease payments and account for them together as a single lease component which increases the amount of the ROU assets and liabilities.

We also elected to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of income on a straight-line basis over the lease term.

Operating leases are included in lease right-of-use assets, current portion of lease right-of-use liabilities, and long-term portion of lease right-of-use liabilities on our condensed consolidated balance sheets. Operating lease expense is recognized on a straight-line basis over the lease term in income from operations on our consolidated statements of income.

Revenue Recognition

We recognize revenues when we transfer control of promised goods or services to our customers in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. Our payment terms vary by the products and services offered. The term between billings and when payment is due is not significant.

Revenues are presented on a disaggregated basis on the consolidated statements of income.operations.

We also provide mailing and shipping services for which the cost of postage or delivery is included in the cost of the service and, therefore, is recognized as service revenue.

Product revenue consists of products sold through the mailing and shipping supplies stores which are available to our customers from within some of our mailing and shipping solutions. Products sold include shipping labels, mailing labels, dedicated postage printers, scales, and other mailing and shipping-focused office supplies. We recognize product revenue on product purchases upon delivery of the order to the customer.

Segment Information

We have organized our operations into two segments: Stamps.com and MetaPack. Please see Note 10 - “Segment and Geographical Information” in our Notes to Consolidated Financial Statements for further description. 

Short-Term Financing Obligations

We utilize short-term financing, which is separate from our debt, to fund certain Company operations.  Short-term financing obligations are included in accounts payable and accrued expenses in the accompanying consolidated balance sheets.  As of March 31, 2018,2019, we had $16.3$18.0 million in short-term financing obligations and $89.2$50.1 million of unused credit. As of December 31, 2017,2018, we had $17.2$23.8 million in short-term financing obligations and $103.4$96.7 million of unused credit.

Stock-Based Compensation

We account for share-based employee compensation plans under the fair value recognition and measurement provisions in accordance with applicable accounting standards, which require all share-based payments to employees, including grants of stock options and restricted stock units (RSUs), to be measured based on the grant date fair value of the awards, with the resulting expense generally recognized on a straight-line basis over the period during which the employee is required to perform service in exchange for the award.

We account for forfeitures as they occur. Prior to the adoption of ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, in 2017, share-based compensation expense was recorded net of estimated forfeitures, which were based on historical forfeitures and adjusted to reflect changes in facts and circumstances, if any.

We use the Black-Scholes-Merton option valuation model to estimate the fair value of share-based payment awards on the date of grant, which requires us to use a number of complex estimates and subjective assumptions, including stock price volatility, expected term, and risk-free interest rates, and projected employee stock option exercise behaviors.rates. In the case of options we grant, our assumption of expected volatility is based on the historical volatility of our stock price over the term equal to the expected life of the options. We base the risk-free interest rate on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life of the options assumed at the date of grant. The estimated expected life represents the weighted average period the stock options are expected to remain outstanding, determined based on an analysis of historical exercise behavior.

Trademarks, Trade Names, and Other Intangible Assets (excluding Goodwill)

Acquired trademarks, trade names, and other intangibles (excluding goodwill) include both amortizable and non-amortizable assets and are included in intangible assets, net in the accompanying consolidated balance sheets. Intangible assets are carried at cost less accumulated amortization. Cost associated with internally developed intangible assets is typically expensed as incurred as research and development costs. Amortization of amortizable intangible assets is calculated on a straight-line basis, which is consistent with the expected future cash flows.

Treasury Stock

During the three-monthsthree months ended March 31, 20182019 and March 31, 2017,2018, we repurchased approximately 235,461 shares and 120,000 shares and 356,000 shares for $23.2$32.0 million and $43.9$23.2 million, respectively. Also, duringin the three-months ended March 31,first quarter of 2019 and the first quarter of 2018, and March 31, 2017, we withheld 21,0761,039 and 6,67021,076 of shares, respectively, to satisfy income tax obligations related to performance-based inducement equity awards issued to the General Manager and the then Chief Technology Officer of ShippingEasyShippingEasy.

Accounting Guidance Adopted in 2019

Disclosure Update and Simplification

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. The Company adopted the new presentation for its consolidated statement of stockholders' equity in the first quarter of 2019.

Leases

In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases, a new accounting standard for leases. The new standard generally requires the recognition of financing and operating lease liabilities and corresponding ROU assets on the balance sheet. For financing leases, a lessee recognizes amortization of the ROU asset as described in an operating expense over the lease term separately from interest on the lease liability. For operating leases, a lessee recognizes its total lease expense as an operating expense over the lease term.Note 2 - “Acquisitions.”

We adopted the new guidance on January 1, 2019 using the modified retrospective transition approach. We elected the practical expedient to apply the new standard to all leases existing at the date of initial application and not restating comparative periods. We also elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification of finance or operating lease, our assessment on whether a contract was or contains a lease, and our initial direct costs for any leases that existed prior to January 1, 2019.

Accounting Guidance Adopted in 2018

Definition of a Business

In January 2017, the FASB issued ASU 2017-01, guidance that changes the definition of a business for accounting purposes. Under the new guidance, an entity first determines whether substantially all of the fair value of a set of assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set of assets is not deemed to be a business. If this threshold is not met, the entity then evaluates whether the set of assets meets the requirement to be deemed a business, which at minimum, requires there to be an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance became effective on a prospective basis for the Company on January 1, 2018. The Company's adoption of the guidance on January 1, 2018 did not have a material impact on the Company’s consolidated financial statements.

Modification of Share-Based Payments

In May 2017, the FASB issued ASU 2017-09, guidance that clarifies when changes to the terms and conditions of share-based awards must be accounted for as modifications. The guidance does not change the accounting treatment for modifications. The guidance became effective for the Company on January 1, 2018 and was adopted on a prospective basis. The adoption of the guidancenew standard on January 1, 2019 resulted in recording operating lease ROU assets and operating lease liabilities of approximately $11.8 million and $13.6 million, respectively. The adoption did not have a material impact on the Company’sour beginning retained earnings, or our prior year condensed consolidated financial statements.
Revenue Recognitionstatements of income and statements of cash flows.

In May 2014,For information regarding the FASB issued ASU 2014-09, Revenue from Contracts with Customers,an updated standard on revenue recognition. This ASU superseded the revenue recognition requirements in Accounting Standards Codification Topic 605, Revenue Recognition,accounting policy and most industry-specific guidance.  ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using U.S. GAAP and International Financial Reporting Standards.  The core principle ofrequired disclosures under the new standard, is for companies to recognize revenue to depict the transfersee “Summary of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies may be required to use more judgment Significant Accounting Policies - Leases” and make more estimates than under current authoritative guidance.
During fiscal 2017, the FASB issued additional clarification guidance on the new revenue recognition standard which also included certain scope improvements and practical expedients. The new revenue recognition standard became effective for the Company on January 1, 2018 and could be applied retrospectively to each prior reporting period presented (full retrospective method) or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method)Note 11 - “Leases,” respectively.
On January 1, 2018, the Company adopted the guidance under the modified retrospective method. The adoption of the guidance did not have a material impact on the Company's consolidated financial statements.

Accounting Guidance Not Yet Adopted

Goodwill Impairment

In January 2017, the FASB issued ASU 2017-04, a standard which simplifies the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.  The guidance will become effective on a prospective basis for the Company on January 1, 2020 and is not expected to have a material impact on the Company's consolidated financial statements.

LeasesFinancial Instruments - Credit Losses

In FebruaryJune 2016, the FASB issued ASU 2016-02,2016-13, a new accounting standard that replaces the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. We will be required to use a forward-looking expected credit loss model for leases.accounts receivables, loans, and other financial instruments. The new standard generally requires the recognition of financing and operating lease liabilities and corresponding right-of-use assets on the balance sheet. For financing leases, a lessee recognizes amortization of the right-of-use asset as an operating expense over the lease term separately from interest on the lease liability. For operating leases, a lessee recognizes its total lease expense as an operating expense over the lease term. The amendments areguidance will become effective for the Company in the first quarter of 2019on January 1, 2020 using a modified retrospective approach with early adoption permitted. The Company is currentlyWe are evaluating the impact of adopting this guidance on the adoption of this standard will have on itsCompany's consolidated financial statements.

We are not aware of any material subsequent events or transactions that have occurred that would require recognition in the financial statements or disclosure in the notes to the financial statements.

2.    Acquisitions

We have accounted for all of our acquisitions under the acquisition method of accounting in accordance with the provisions of FASB ASC Topic No. 805, Business Combinations.

ShippingEasyMetaPack Acquisition

On July 1, 2016,August 15, 2018, we, through our wholly owned subsidiary Pacific Shelf 1855 Limited (Pacific Shelf), completed ourthe acquisition of ShippingEasy Group,MetaPack Limited, a private limited company incorporated in England and Wales, pursuant to a share purchase agreement dated July 24, 2018, as amended (the “Agreement”), by and among certain key sellers named in the Agreement (the “Key Sellers”), MetaPack, Pacific Shelf, and Stamps.com Inc. (ShippingEasy). The netas Pacific Shelf’s guarantor. MetaPack provides multi-carrier enterprise-level solutions to many of the world’s preeminent e-commerce retailers and brands.
Pursuant to the Agreement and a related agreement to purchase Minority Shares (as defined below), Pacific Shelf acquired 100% of MetaPack’s issued and to be issued share capital by purchasing (i) all of the Key Sellers’ shares of MetaPack, representing approximately 80% of the total outstanding shares and (ii) all other issued and to be issued shares of MetaPack (Minority Shares), for a final adjusted purchase price, including adjustments for net working capital totaledall such shares, of approximately $55.4£171 million, andor $217.7 million using the August 15, 2018 GBP to USD exchange rate. Total cash paid for the acquisition was funded from current cash and investment balances.

In connectionStamps.com granted inducement stock options for an aggregate of 320,250 shares of Stamps.com common stock to 72 new employees after completion of its acquisition of MetaPack. The stock options were granted as inducements material to the new employees entering into employment with Stamps.com, pursuant to the Stamps.com 2018 MetaPack Equity Inducement Plan, which was approved by Stamps.com’s Compensation Committee. The awards were granted without stockholder approval in accordance with Nasdaq Listing Rule 5635(c)(4). Each option vests 25% on the one year anniversary of the grant date with the remaining 75% vesting in approximately equal monthly increments over the succeeding thirty-six months, provided that the option holder is still employed by Stamps.com or one of its subsidiaries on the vesting dates. The stock options have a ten year term and an exercise price equal to closing price of Stamps.com common stock on the grant date of August 15, 2018.

Under the acquisition method of accounting under ASC 805, the total purchase price of the acquired company is allocated to the assets acquired and the liabilities assumed based on their fair values. We have made significant estimates and assumptions in determining the preliminary allocation of the purchase price. The Company has made a preliminary allocation of the purchase price of MetaPack to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair value. The preliminary allocation of the purchase price is based upon management's estimates and is subject to revision, as a more detailed analysis of intangible assets and tax and other liabilities is completed and additional information on the fair value of assets and liabilities becomes available. A change in the fair value of the net assets may change the amount of the purchase price allocable to goodwill, and could impact the amounts of amortization expense.
The purchase price of MetaPack has been allocated on a preliminary basis as follows to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair value based on the August 15, 2018 GBP to USD exchange rate (in thousands, except years):

The fair value of the assets acquired and liabilities assumed were preliminarily determined using income, cost and market participant approaches. The fair value measurements were primarily based on significant inputs that are not observable in the market and thus represent a Level 3 measurement as defined in ASC 820. The identified intangible assets consist of trade names, developed technology, and customer relationships. The estimated fair values of the trade names and developed technology were determined using the “relief from royalty” method. The estimated fair value of customer relationships was determined using the “excess earnings” method. The rate utilized to discount net cash flows to their present values was approximately 15% and was determined after consideration of the overall enterprise rate of return and the relative risk and importance of the assets to the generation of future cash flows. Intangible assets are being amortized on a straight-line basis over their estimated useful lives. Based on the August 15, 2018 exchange rate, we expect the amortization of acquired intangibles will be approximately $1.6 million per quarter for the remaining estimated useful lives.

Deferred taxes were adjusted to record the deferred tax impact of acquisition accounting adjustments primarily related to intangible assets. The incremental deferred tax liabilities were calculated based on the tax effect of the step-up in book basis of the net assets of MetaPack, excluding the amount attributable to goodwill, using the estimated statutory tax rates.

Goodwill represents the excess of the consideration given over the sum of the fair values assigned to identifiable assets acquired less liabilities assumed in a business combination. The goodwill balance is primarily attributable to the expanded market opportunities for the Company internationally and MetaPack in the United States and the Company's ability to generate future technology. None of the goodwill recognized is expected to be deductible for income tax purposes. The goodwill recorded as part of this acquisition is included in the MetaPack segment (see Note 6 - “Goodwill and Intangible Assets” in our Notes to Consolidated Financial Statements).

Immediately following the acquisition, we issued performance-based inducement equity awards to eachrepaid in full MetaPack's existing revolving credit facility balance of the General Manager and Chief Technology Officer of ShippingEasy. These inducement awards cover an aggregate of up to 43,567 common shares each if earnings targets for ShippingEasy are achieved over a two and one-half year period which began July 1, 2016. The awards are subject to proration if at least 75% of the applicable target is achieved and are subject to forfeiture or acceleration based on changes in employment circumstances over the performance period.approximately $12.7 million.

In fiscal 2016, we determined the achievement of 100% of the earnings target for the six months ended December 31, 2016 was probable, therefore, we recognizedWe incurred approximately $1.9$2.5 million in transaction costs included in general and administrative expense and $1.0 million of stock-based compensation expense, representing 21,783 shares, for these inducement equity awards duringnonrecurring foreign currency exchange loss directly related to the six months ended December 31, 2016. The equity award for the first phase was issued in the first quarter of 2017 with 15,113 shares distributed and 6,670 shares withheld to satisfy income tax obligations. In fiscal 2017, we determined the achievement of 100% of the earnings target for the twelve months ended December 31, 2017 was probable, therefore, we recognized approximately $4.9 million of stock-based compensation expense, representing 56,638 shares, for these inducement equity awardsacquisition during the year ended December 31, 2017. The equity award for the second phase was issued in the first quarter of 2018 with 35,562 shares distributed and 21,076 shares withheld to satisfy income tax obligations. In the first quarter of 2018, we determined the achievement of 100% of the earnings target for the twelve months ended December 31, 2018 is probable, therefore, we recognized approximately $189,000 of stock-based compensation expense, representing 25% of the 8,713 shares that would be earned in the year ending December 31, 2018, for these inducement equity awards during the three months ended March 31, 2018.

We also issued inducement stock option grants for an aggregate of approximately 62,000 shares of Stamps.com common stock to 48 new employees in connection with our acquisition of ShippingEasy.

On February 8, 2018, a putative class action complaint was filed against us in a case entitled Juan Lopez and Nicholas Dixon v. Stamps.com, Inc., Case No. 2:18-cv-01101, in the United States District Court for the Central District of California, Western Division, alleging wage and hour claims on behalf of our current and former “non-exempt” hourly call center employees. The complaint seekssought class certification, unspecified damages, unpaid wages, penalties, restitution, interest, and attorneys’ fees and costs. On July 24, 2018, we entered into a preliminary settlement that would resolve this matter for a non-material payment to be distributed to the participating class members. The court granted preliminary approval of the settlement and, at a hearing held on April 29, 2019, requested additional documentation. Therefore the timing of final approval of the settlement is now pending court approval at a time convenient to the court.

On February 28, 2019, a putative class action complaint was filed against us in a case entitled Grabisch v. Stamps.com, Inc. et al, Case No. 2:19-cv-01497, in the United States District Court for the Central District of California, Western Division, alleging violations of the Securities Exchange Act of 1934 purportedly on behalf of all those who purchased, or otherwise acquired, Stamps.com common stock between May 3, 2017 and February 21, 2019. On March 13, 2019, a second putative class action complaint, with the same allegations, was filed against us in a case entitled Karinski v. Stamps.com, Inc. et al, Case 2:19-cv-01828, in the United States District Court for the Central District of California, Western Division. On April 22, 2019, the Grabisch action was dismissed in its entirety without prejudice. The remaining Karinski complaint seeks class certification, unspecified damages, attorneys’ fees and costs. Lead plaintiff motions were filed on April 29, 2019, but a lead plaintiff has not yet been appointed and a consolidated complaint has not yet been filed. We expectbelieve that the case is without merit and intend to defend this case vigorously. Due to the preliminary naturevery recent filing date of the case, neither the likelihood that a loss, if any, will be realized, nor an estimate of the possible loss or range of loss, if any, cannotcan be determined.

7.    Income Taxes

Our income tax expense was $6.7 million for the three months ended March 31, 20182019. The income tax expense for the three months ended March 31, 2019 was primarily due to (a) our pre-tax income multiplied by an estimated annual effective tax rate and 2017(b) discrete tax benefits related to the exercises of stock awards of approximately $0.4 million. Our income tax expense was $1.6 million and $660,000, respectively.for the three months ended March 31, 2018. The income tax expense for the three months ended March 31, 2018 was primarily due to (a) our pre-tax income multiplied by an estimated annual effective tax rate and discrete tax benefits of approximately $10.7 million recorded during the quarter related to exercises of stock awards.  The income tax expense for the three months ended March 31, 2017 was primarily due to our pre-tax income multiplied by an estimated annual effective tax rate and discrete tax benefits of approximately $12.6 million recorded during the quarter related to exercises of stock awards. Our income tax expense for the three months ended March 31, 2018 was higher than our income tax expense for the three months ended March 31, 2017 primarily due to higher pre-tax income and lower(b) discrete tax benefits related to the exercises of stock awards.


awards of approximately $10.7 million.

Our effective income tax rate differs from the statutory income tax rate primarily as a result of permanent tax adjustments for non-deductible expenses, state taxes, and tax benefits from exercises of stock awards and research and development tax credits as well as nondeductible items and state taxes.exercises of stock awards. As of March 31, 20182019 and December 31, 2017,2018, we have recorded a valuation allowance of $490,000$1.3 million and $410,000$1.2 million against certain state research and development credits for which we believe it is more likely than not that these deferred tax assets will not be realized. We also have recorded a valuation allowance against the activity of certain foreign jurisdictions.

We recorded provisional amounts as of December 31, 2017 related to certain income tax effects of the Tax Cuts and Jobs Act
enacted December 22, 2017 under guidance set forth in Staff Accounting Bulletin No. 118 (SAB 118). These amounts have not been adjusted as of March 31, 2018, and we will continue to monitor any changes to the provisional amounts during the measurement period or until the accounting is complete. Any subsequent adjustment to the these amounts will be recorded to current tax expense in the quarters of 2018 when the analysis is complete.

8.    Fair Value Measurements

Financial assets measured at fair value on a recurring basis are classified in one of the three categories described below:

Level 1 - Valuations based on unadjusted quoted prices for identical assets in an active market

Level 2 - Valuations based on quoted prices in markets where trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets
 
Level 3 - Valuations based on inputs that are unobservable and involve management judgment and our own assumptions about market participants and pricing

10.    Segment Information and Geographic Data

Segment Information

Operating segments are defined as components of an enterprise for which discrete financial information is available that is evaluated regularly by the chief operating decision maker (CODM) for purposes of allocating resources and evaluating financial performance. The Company's Chairman and Chief Executive Officer has been identified as the CODM as defined by guidance regarding segment disclosures.
The Company’s reportable segments have been determined based on the distinct nature of their operations and customer bases, and the financial information that is evaluated regularly by the CODM. Following the MetaPack acquisition (see Note 2) in 2018, the Company added a new segment for the MetaPack business. Previously, the Company had a single reportable segment.
The Stamps.com segment derives revenue from external customers from offering postage online and shipping software solutions offered to consumers, small businesses, e-commerce shippers, enterprise mailers, and high volume shippers. The Stamps.com reportable segment includes the results of brand names Stamps.com, Endicia, ShippingEasy, ShipStation, and ShipWorks. Stamps.com's customers are primarily located in the US.
The MetaPack segment consists of the operations of MetaPack which derives revenues from external customers from offering multi-carrier enterprise-level shipping software solutions to large e-commerce retailers and brands. MetaPack's customers are primarily located outside the US.
Revenues, cost of revenues, and operating expenses are generally directly attributed to our segments. Inter-segment revenues are not presented separately, as these amounts are immaterial. Our CODM does not evaluate operating segments using asset information.

We are not aware of any material subsequent events or transactions that have occurred that would require recognition in the financial statements or disclosure in the notes to the financial statements, except as described below and in Note 3 - “Commitments and Contingencies” in our Notes to Consolidated Financial Statements.

Prior to issuance, we became aware of potential adverse amendments, renegotiations, changes, or termination of certain contracts between the USPS and certain of our strategic partners who are part of the USPS’s reseller program, and through which we derive material revenues and profits (such potential events, collectively the "Reseller Restructuring"); however there is significant uncertainty as to whether, how and when any Reseller Restructuring may be implemented. As such, an estimate of any future financial impact for accounting purposes cannot be made at this time.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Quarterly Report on Form 10-Q (this "Report") contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). You can find many (but not all) of these statements by looking for words such as "approximates," "believes," "expects," "anticipates," "estimates," "projects," "seeks," "intends," "plans," "could," "would," "may" or other similar expressions in this Report. Our forward-looking statements relate to future events or our future performance and include, but are not limited to, statements concerning our business strategy, future commercial revenues, market growth, capital requirements, new product introductions, expansion plans and the adequacy of our funding. Other statements contained in this Report that are not historical facts are also forward-looking statements.

We claim the protection of the safe harbor contained in the Private Securities Litigation Reform Act of 1995.  We caution investors that any forward-looking statements presented in this Report, or that we may make orally or in writing from time to time, are based on beliefs and assumptions made by us and information available to us at the time made.  Such statements are based on assumptions, and the actual outcome will be affected by known and unknown risks, trends, uncertainties, and factors that are beyond our control or ability to predict. Although we believe that our assumptions are reasonable, they are not guarantees of future performance, and some will inevitably prove to be incorrect. As a result, our actual future results can be expected to differ from our expectations, and those differences may be material. Accordingly, investors should use caution in relying on forward-looking statements to anticipate future results or trends.

Please refer to the risk factors under "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 20172018, as well as those described elsewhere in this Report and in our other public filings.  The risks included are not exhaustive, and additional factors could adversely affect our business and financial performance. We operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time, and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. This Report and all subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We do not undertake any obligation to release publicly any revisions to our forward-looking statements to reflect events or circumstances after the date of this Report.

Product revenue is primarily driven by labels,label sales, such as NetStamps, and DYMO Stamps, which are used for mailing. As our growth in postage has been driven more by shipping than mailing over the recent years, our product revenue has not kept pace with our growth in total revenue and is approximately flat year over year.

On November 18, 2015, we entered into a Credit Agreement with a group of banks, which provided for a term loan of $82.5 million and a revolving credit facility with a maximum borrowing of $82.5 million. Our Credit Agreement matures on November 18, 2020. In connection with entering into the Credit Agreement, we incurred approximately $1.8 million in debt issuance costs which were recorded as debt discount and are being accreted as interest expense over the life of the Credit Agreement. Interest expense associated with the debt issuance costs for botheach of the three months ended March 31, 20182019 and 2017March 31, 2018 was approximately $93,000. In December 2017, we repaid all of our revolving credit facility outstanding debt of $62.0 million.

Borrowings under the term loan are payable in quarterly installments which began on December 31, 2015. We pay interest on our Credit Agreement equal to the London Interbank Offered Rate plus an applicable margin, between 1.25% and 2.00%, based upon certain financial measures. As of March 31, 2018,2019, our applicable margin was our applicable margin was 1.25% and the interest rate on our outstanding loan was approximately 3.24%3.75%. We are subject to certain customary quarterly financial covenants under our Credit Agreement such as a maximum total leverage ratio and a minimum fixed charge coverage ratio. As of March 31, 2018,2019, we were in compliance with the covenants of the Credit Agreement.

The Credit Agreement includes negative covenants, subject to exceptions, restricting or limiting our ability to among other things, incur additional indebtedness; grant liens; repurchase stock; pay dividends; and engage in certain investment, acquisition, and disposition transactions. The Credit Agreement imposes certain requirements in order for us to make dividend payments. As of March 31, 2018,2019, such requirements were: (1) our Consolidated Total Leverage Ratio, as defined in the Credit Agreement, must be less than 2.752.50 to 1.00; (2) our Fixed Charge Coverage Ratio, as defined in the Credit Agreement, must be greater than 1.25 to 1.00; and (3) our Liquidity as defined in the Credit Agreement must be greater than $20 million. As of March 31, 2018,2019, our Consolidated Total Leverage Ratio was 0.280.25 to 1.00, our Fixed Charge Coverage Ratio was 23.1916.92 to 1.00 and our Liquidity was approximately $278$193 million, which includes cash and cash equivalent balances, as well as the available balance under the revolving credit facility. Based on our actual financial condition and results of operations, we do not believe that the provisions of the Credit Agreement currently represent a restriction to our ability to pay dividends in permissible amounts.

Immediately following the acquisition of MetaPack, we repaid in full MetaPack's existing revolving credit facility balance of approximately $12.7 million.

We believe our available cash and marketable securities, together with the cash flow from operations, will be sufficient to fund our business for at least the next twelve months.


Segment Analysis

We acquired MetaPack on August 15, 2018, and, accordingly, there is no inclusion of MetaPack’s results prior to our ownership within this Report. Given the absence of MetaPack data in our results prior to our ownership of MetaPack, and the inclusion of segment financial information contained in Note 10 to the Notes to Consolidated Financial Statements contained in this Report, we believe that, as of the filing of this Report, a segment presentation in this Management's Discussion and Analysis of Results of Operations section is not necessary to form an understanding of our overall business. We intend to provide a segment analysis in our future Management's Discussion and Analysis of Results of Operations sections when appropriate to facilitate an understanding of our business.

Business Outlook and Forward-Looking Statements

The following forward-looking statements are accompanied by, and should only be read in conjunction with, the qualifications and limitations described in the forward-looking statements discussion at the beginning of this Item 2 and the risks and other factors set forth in Item 1A "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 20172018, filed with the SEC on February 28, 2018.March 1, 2019.

As previously disclosed, our agreement with the USPS that provided for Package Incentive Payments to be paid directly to us by the USPS for certain classes of shipping labels terminated on December 31, 2018. In addition, we have recently become aware of potential adverse amendments, renegotiations, changes, or termination of certain contracts between the USPS and certain of our strategic partners who are part of the USPS’s reseller program, and through which we derive material revenues and profits (such potential events, collectively the "Reseller Restructuring"); however there is significant uncertainty as to whether, how and when any Reseller Restructuring may be implemented.
We expect our mailing and shipping revenue to increasedecrease in 20182019 compared to 2017. We expect our mailing and shipping revenue growth in 2018 primarily due to be less than the growth we achieved in 2017 now that we have passed the one year anniversarytermination on December 31, 2018 of our ShippingEasy acquisition.agreement with the USPS which provided for Package Incentive Payments and the potential Reseller Restructuring, partially offset by an increase due to MetaPack results being included for the full fiscal year in 2019, compared to the period from August 15 through year end in 2018. Our ability to grow our mailing and shipping revenue is partlyalso dependent on our ability to increase our sales and marketing spend to acquire new customers and to retain our existing customers. To the extent we are not able to achieve our target increase in spending and acquire or retain customers, this would further negatively impact our 20182019 mailing and shipping revenue growth expectations.

Our expectations of mailing and shipping revenue reflect the discontinuation of Package Incentive Payments as well as the uncertainty regarding any potential Reseller Restructuring. As a result, our revenue and operating results will be adversely affected unless we are successful in timely replacing the lost revenue with similar compensation from the USPS or other potential partners. While we have strategies to replace some portion of these revenues with new carrier relationships, these plans are in various stages, and we do not expect any material replacement of such revenues to occur during the 2019 fiscal year. Further, there is no assurance as to when, if or to what extent we may ultimately succeed in implementing such strategies, all of which carry negotiation and execution risks. Unless and until we replace these lost revenues and associated profit margins, our operating results in 2019 and beyond may be materially less than in 2018. See "Risk Factors--Risks Related to our Industry--The discontinuation of certain financial compensation arrangements with the USPS will have an adverse effect on our revenues and operating results, unless we are successful in replacing the lost revenue and profit with similar compensation from the USPS or other potential partners, of which there is no assurance," "Risk Factors--Risks Related to our Industry--The USPS could modify, discontinue or terminate agreements and other financial compensation arrangements, which would have an adverse effect on our revenue and operating results," "Risk Factors--Risks Related to our Industry--The USPS or our integration partners could cause discounts our customers receive to be diminished or terminated, which would have an adverse effect on our results of operations, reputation and competitiveness," and "Risk Factors--Risks Related to our Industry--Strategic business Partners or carriers could modify or terminate agreements and other financial compensation arrangements, which could materially adversely affect our results of operations and prospects," in our Annual Report on Form 10-K for the fiscal year ended December 1, 2018, filed with the SEC on March 1, 2019.
We expect customized postage revenue to decline in 20182019 compared to 2017,2018, due to certain high volume business purchases occurring in 2017,2018, which may not be repeated in 2018.2019. High volume business orders for customized postage can fluctuate significantly from quarter to quarter and therefore historical trends may not be indicative of future results for customized postage revenue.

We expect our sales and marketing expenseexpenses to increasebe higher in 20182019 as compared to 2017. We2018 and we expect the percent increase in sales and marketing expense in 20182019 to be greaterless than the percent increase in 20172018. The increases are as wea result of the inclusion of MetaPack, the annualized effect of our headcount investments in 2018, and our plan to increase our investments in headcount and non-headcount resources in 20182019 to drive growth. We will continue to monitor our customer metrics and the state of the economy and adjust our level of spending accordingly. Sales and marketing spend is expensed in the period incurred, while the revenue and profits associated with the acquired customers are earned over the customers’ lifetimes. As a result, increased sales and marketing spend in future periods could result in a reduction in operating profit and cash flow compared to past periods.

We expect research and development expenses to be higher in 20182019 as compared to 2017 as2018 and we expect to hire additional research and development personnel in 2018. We expect the percent increase in research and development expense in 20182019 to be lessgreater than the percent increase in 2017.

2018. The increases are a result of the inclusion of MetaPack, the annualized effect of our headcount investments in 2018, and our plan to increase our investments in headcount resources in 2019 to drive growth.
We expect general and administrative expenses to be higher in 20182019 as compared to 2017 as we expect to hire additional general and administrative personnel2018. The increase is a result of the inclusion of MetaPack, the annualized effect of our headcount investments in 2018, and our plan to continue to incur sales tax expense.increase our investments in headcount resources in 2019. We expect the percent increase in general and administrative expense in 20182019 to be greaterless than the percent increase in 2017.

2018.
We expect our stock-based compensation expense to be lowerhigher in 20182019 compared to 2017 due to smaller executive grants in 2018.

We expect our interest expenseand other income (expense), net in 20182019 to be lower than 2017approximately similar to 2018 due to higher expected interest rates, partially offset by lower outstanding debt balances under our credit facility.

balances.
We expect our effective tax rate for 20182019 to be higher than 2017 as we benefited from excess2018. The increase in our estimated effective tax benefitsrate for 2019 was primarily driven by an increase in projected non-deductible expenses related to the exercise of stock optionsexecutive compensation coupled with a reduction in 2017 which we do not expect to recur at the same levels in 2018. However, there are other factors that impact taxable income compared toprojected pre-tax book income which can be difficult to predict and can change from quarter-to-quarter.

income.
As discussed earlier in this Report, our expectations are subject to substantial uncertainty and our results are subject to macro-economic factors and other factors which could cause these trends to be worse than our current expectation or which could cause actual results to be materially different than our current expectations. These expectations are “forward looking statements,” are made only as of the date of this Report and are subject to the qualifications and limitations on forward-looking statements discussion in the beginning of Item 2 of this Report and the risks and other factors set forth in Item 1A of Part II of this Report and Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2017,2018 filed with the SEC on February 28, 2018.March 1, 2019. Our business has grown through acquisitions during 2014 through 2016;2018; however the expectations above do not assume any future acquisitions or dispositions, any of which could have a significant impact on our current expectations. As described in our forward-looking statements discussion, we do not undertake any obligation to release publicly any revisions to our forward-looking statements to reflect events or circumstances after the date of this Report.


Critical Accounting Policies and Judgments

Management's discussion and analysis of our financial condition and results of operations is based on our unaudited financial statements. The preparation of these financial statements is based on the selection of accounting policies and the application of significant accounting estimates, some of which require management to make judgments, estimates, and assumptions that affect the amounts reported in the financial statements and notes. Except as noted below, forFor more information regarding our critical accounting estimates and policies, see Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations-Critical Accounting Policies and Judgments" of our Annual Report on Form 10-K for the year ended December 31, 2017,2018, filed with the SEC on February 28, 2018.March 1, 2019.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOUSURESDISCLOSURES ABOUT MARKET RISK

On November 18, 2015, we entered into a Credit Agreement with a group of banks, which provided for a term loan of $82.5 million and a revolving credit facility with a maximum borrowing of $82.5 million. Our Credit Agreement matures on November 18, 2020. As of March 31, 2018,2019, the debt outstanding under our Credit Agreement, gross of debt issuance costs, was $68.1$58.8 million.  Borrowings under the term loan are payable in quarterly installments which began on December 31, 2015. We pay interest on our Credit Agreement at a rate equal to the London Interbank Offered Rate plus an applicable margin, which is between 1.25% and 2.00%, based upon certain financial measures. As of March 31, 2018,2019, our applicable margin was our applicable margin was 1.25% and the interest rate on our outstanding loan was approximately 3.24%3.75%. Interest expense would not be significantly affected by either a 10% increase or decrease in the rates of interest on our debt.

We do not hold or issue financial instruments for trading purposes. We do not have material exposure to market risk with respect to investments. We do not useduse derivative financial instruments in our investment portfolio.  None of the instruments in our investment portfolio are held for speculative or trading purposes. However, we may adopt specific hedging strategies in the future.

Our cash equivalents consist primarily of money market securities and had a weighted average maturity of 2716 days and a weighted average interest rate of 1.4%2.4% at March 31, 2018.2019. The aggregate value of our cash and cash equivalents was $195.8$110.9 million at March 31, 2018.2019. Interest rate fluctuations impact the carrying value of the portfolio. The fair value of our portfolio of marketable securities would not be significantly affected by either a 10% increase or decrease in the rates of interest due primarily to the short-term nature of the portfolio. We do not believe that the future market risks related to the above securities will have a material adverse impact on our financial position, results of operations, or liquidity.
