~~The accompanying notes are an integral part of the consolidated financial statements.~~

See ~~TECO Energy, Inc.’s 2015~~TEC’s Annual Report on Form 10-K for the year ended December 31, 2016 for a complete discussion of ~~the company’s~~ accounting policies. The significant accounting policies for ~~all utility and diversified operations~~TEC include:

For the purposes of its consolidated financial reporting, TEC is comprised of the electric division, referred to as Tampa Electric, and the natural gas division, referred to as PGS.

Intercompany balances and transactions within the divisions have been eliminated in consolidation. In the opinion of management, the unaudited consolidated condensed financial statements include all adjustments that are of a recurring nature and necessary to state fairly the financial position of ~~TECO Energy, Inc. and its subsidiaries~~TEC as of ~~Sept.~~September 30, ~~2016~~2017 and ~~Dec.~~December 31, ~~2015,~~2016, and the results of operations and cash flows for the periods ended ~~Sept.~~September 30, ~~2016~~2017 and ~~2015.~~2016. The results of operations for the three and nine months ended ~~Sept.~~September 30, ~~2016~~2017 are not necessarily indicative of the results that can be expected for the entire fiscal year ending ~~Dec.~~December 31, ~~2016.~~2017.

The use of estimates is inherent in the preparation of financial statements in accordance with U.S. GAAP. Actual results could differ from these estimates. The year-end consolidated condensed balance sheet data was derived from audited financial statements; however, this quarterly report on Form 10-Q does not include all year-end disclosures required for an annual report on Form 10-K by U.S. GAAP.

TEC is a wholly owned subsidiary of TECO Energy. On July 1, 2016, TECO Energy and Emera completed the Merger contemplated by the Merger Agreement entered into on ~~Sept.~~September 4, 2015. ~~As a result of the Merger, the Merger Sub Company merged with and into TECO Energy with TECO Energy continuing as the surviving corporation and becoming~~Therefore, TEC continues to be a wholly owned ~~indirect~~ subsidiary of ~~Emera.~~TECO Energy and became an indirect wholly owned subsidiary of Emera as of July 1, 2016. The acquisition method of accounting was not pushed down to TECO Energy or its ~~subsidiaries. See~~ ~~Note 14~~ ~~for further information.~~subsidiaries, including TEC.

As of ~~Sept.~~September 30, ~~2016~~2017 and ~~Dec.~~December 31, ~~2015,~~2016, unbilled revenues of ~~$71.3~~$71 million and ~~$81.1~~$54 million, respectively, are included in the “Receivables” line item on the Consolidated Condensed Balance Sheets.

Tampa Electric and PGS are allowed to recover certain costs from customers on a dollar-per-dollar basis through rates approved by the FPSC. The amounts included in customers’ bills for franchise fees and gross receipt taxes are included as revenues on the Consolidated Condensed Statements of Income. Franchise fees and gross receipt taxes payable by Tampa Electric and PGS are included as an expense on the Consolidated Condensed Statements of Income in “Taxes, other than income”. These amounts totaled ~~$32.6~~$31 million and ~~$89.2~~$86 million for the three and nine months ended ~~Sept.~~September 30, ~~2016,~~2017, respectively, ~~compared to $31.7~~and $33 million and ~~$88.3~~$89 million for the three and nine months ended ~~Sept.~~September 30, ~~2015,~~2016, respectively.

NMGC is an agent in the collection and payment of franchise fees and gross receipt taxes and is not required by a tariff to present the amounts on a gross basis. Therefore, NMGC’s franchise fees and gross receipt taxes are presented net with no line-item impact on the Consolidated Condensed Statements of Income.

~~The new U.S. GAAP accounting policies that are applicable to and were adopted by the company are described as follows:~~

~~In April 2015, the FASB issued Accounting Standard Update (ASU) 2015-03,~~ ~~Interest – Imputation of Interest~~, which simplifies the presentation of debt issuance costs. The amendments require debt issuance costs be presented on the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs is not affected. The company adopted this standard in the first quarter of 2016, and Dec. 31, 2015 balances have been retrospectively restated. This change resulted in $27.7 million of debt issuance costs as of Dec. 31, 2015, previously presented as “Deferred charges and other assets”, being reclassified as a deduction from the carrying amount of the related “Long-term debt, less amount due within one year” line item on its Consolidated Condensed Balance Sheet. In accordance with ASU 2015-15 ~~Interest: Imputation of Interest~~, the company continues to present debt issuance costs related to its letter of credit arrangements and related instruments in “Prepayments and other current assets” on its Consolidated Condensed Balance Sheets.

~~Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships~~

~~In March 2016, the FASB issued ASU 2016-05,~~ ~~Derivatives and Hedging Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.~~ The standard clarifies that a change in the counterparty to a derivative contract, in and of itself, does not require the dedesignation of a hedging relationship provided that all other hedge accounting criteria continue to be met. The company early adopted in the third quarter of 2016 as permitted.

~~In March 2016, the FASB issued ASU 2016-09,~~ ~~Compensation – Stock Compensation~~ to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, accounting for forfeitures, classification of awards as either equity or liabilities, and presentation on the statement of cash flows. The company early adopted as permitted in the first quarter of 2016. Each aspect has an accounting impact and was implemented as follows:

~~The company~~TEC considers the applicability and impact of all ~~ASUs~~Accounting Standard Updates (ASU) issued by the FASB. The ~~following updates~~ASUs that have been issued, ~~by FASB~~ but ~~have~~that are not yet ~~been adopted by TECO Energy. Any ASUs not included below were assessed and determined to be either not applicable to~~effective, are consistent with those disclosed in TEC’s Annual Report on Form 10-K for the ~~company or are not expected to have a material impact on~~year ended December 31, 2016, with the ~~consolidated financial statements.~~

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which creates a new, principle-based revenue recognition ~~framework.~~framework, codified as Accounting Standards Codification (ASC) Topic 606. The ~~core principle is that a company should recognize revenue when it transfers promised goods or services~~FASB issued amendments to ~~customers in an amount that reflects the consideration~~ASC Topic 606 during 2016 to ~~which the company expects~~clarify certain implementation guidance and to ~~be entitled to.~~reflect scope improvements and practical expedients. The guidance will require additional disclosures regarding the nature, amount, timing and uncertainty of revenue and related cash flows arising from contracts with customers. This guidance will be effective for annual reporting periods, including interim reporting

within those periods, beginning ~~in 2018, with early adoption permitted in~~after December 15, 2017 and will allow for either full retrospective adoption or modified retrospective adoption. ~~The company~~TEC will adopt this guidance effective ~~Jan.~~January 1, ~~2018. The company has developed~~2018, using the modified retrospective approach.

TEC implemented a revenue recognition project plan in 2016. In the first quarter of 2017, TEC concluded that the accounting for contributions in aid of construction will be out of the scope of the new standard. In the second quarter of 2017, TEC completed an ~~implementation plan~~analysis of material regulated revenue streams and ~~is continuing to evaluate the available adoption methods. While the company does not expect the impact to~~collectibility risk and concluded that there will be ~~significant, it is continuing to evaluate the impact of~~no material changes on adoption of this standard. In the third quarter of 2017, TEC evaluated the disclosure requirements and determined that the disaggregation of revenue information required by the new standard will not have a significant impact on ~~its consolidated~~TEC’s information gathering processes and procedures as the revenue information required by the standard is consistent with historical revenue information gathered by TEC for financial ~~statements~~reporting purposes. TEC continues to monitor the assessment of ASC Topic 606 by the AICPA Power and ~~disclosures.~~Utilities Revenue Recognition Task Force for developments.

~~Financial Instruments –~~ Recognition and Measurement of Financial Assets and Financial Liabilities

In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Recognition and Measurement of Financial Assets and Financial ~~Liabilities.~~ Liabilities. The standard provides guidance for the recognition, measurement, presentation and disclosure of financial assets and liabilities. ~~The company~~This guidance will be effective for annual reporting periods, including interim reporting within those periods, beginning after December 15, 2017.

This guidance will be~~new disclosure requirements effective ~~for annual reporting periods, including interim reporting within those periods, beginning after Dec. 15, 2017.~~ January 1, 2018 and does not expect a significant impact.

In February 2016, the FASB issued ASU 2016-02, ~~Leases.~~ Leases. The standard, codified as ASC Topic 842, increases transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet for leases with terms of more than 12 months.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities which amends the hedge accounting recognition and presentation requirements in ASC 815. This standard improves the transparency and understandability of information about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities and simplifies the application of hedge accounting. The standard will make more financial and nonfinancial hedging strategies eligible for hedge accounting, amends the presentation and disclosure requirements for hedging activities and changes how entities assess hedge effectiveness.

Tampa Electric’s ~~retail business~~results reflect the stipulation and ~~PGS~~settlement agreement entered into on September 6, 2013, between Tampa Electric and the intervenors in its Tampa Electric division base rate proceeding, which resolved all matters in Tampa Electric’s 2013 base rate proceeding. On September 11, 2013, the FPSC unanimously voted to approve the stipulation and settlement agreement.

This agreement provided for the following revenue increases: $58 million effective November 1, 2013, an additional $8 million effective November 1, 2014, an additional $5 million effective November 1, 2015, and an additional $110 million effective the date that the expansion of Tampa Electric’s Polk Power Station went into service, which was January 16, 2017. The agreement also provided for Tampa Electric’s allowed regulatory ROE to be a mid-point of 10.25% with a range of plus or minus 1%, with a potential increase to 10.50% if U.S. Treasury bond yields exceed a specified threshold. The agreement provided that Tampa Electric cannot file for additional base rate increases to be effective sooner than January 1, 2018, unless its earned ROE were to fall below 9.25% (or 9.5% if the allowed ROE were increased as described above) before that time. If its earned ROE were to rise above 11.25% (or 11.5% if the allowed ROE were increased as described above) any party to the agreement other than Tampa Electric could seek a review of its base rates. Under the agreement, the allowed equity in the capital structure is 54% from investor sources of capital and Tampa Electric began using a 15-year amortization period for all computer software beginning on January 1, 2013.

On September 27, 2017, Tampa Electric filed with the FPSC an amended and restated settlement agreement that replaces the existing 2013 base rate settlement agreement discussed above and extends it another four years through 2021. The FPSC approved the agreement on November 6, 2017.

The amended agreement provides for solar base rate adjustments (SoBRAs) for TEC’s substantial investments in solar generation. It includes the following SoBRAs: $31 million for 150 MWs effective September 1, 2018, $51 million for 250 MWs effective January 1, 2019, $31 million for 150 MWs effective January 1, 2020, and an additional $10 million for 50 MWs effective on January 1, 2021. In order for each tranche of SoBRA to take effect, Tampa Electric must show they are ~~regulated separately~~cost-effective and each individual project has a cost cap of $1,500/kWac. Additionally, in order to build the last tranche of 50 MWs, the first two tranches of 400 MW must be constructed at or below $1475/kWac. The agreement includes a sharing provision that allows Tampa Electric to retain 25% of any cost savings for projects below $1500/kWac. Tampa Electric plans to invest approximately $850 million in these solar projects over four years and will accrue AFUDC during construction.

The agreement maintains Tampa Electric’s allowed regulatory ROE at a mid-point of 10.25% with a range of plus or minus 1%, with a potential increase to 10.50% if U.S. Treasury bond yields exceed a specified threshold. The agreement provides that Tampa Electric cannot file for additional base rate increases to be effective sooner than January 1, 2022, unless its earned ROE were to fall below 9.25% (or 9.5% if the allowed ROE were increased as described above) before that time. If its earned ROE were to rise above 11.25% (or 11.5% if the allowed ROE were increased as described above) any party to the agreement other than Tampa Electric could seek a review of its base rates. Under the agreement, the allowed equity in the capital structure remains at 54%. The agreement contains certain customer protections related to potential changes in federal tax policy. An asset optimization provision that allows Tampa Electric to share in the savings for optimization of its system once certain thresholds are crossed is also included and Tampa Electric agrees to a five-year financial hedging moratorium for natural gas and no investments in gas reserves.

Prior to the September 6, 2013 stipulation and settlement agreement, Tampa Electric was accruing $8 million annually to an FPSC-approved self-insured storm reserve. Effective November 1, 2013, Tampa Electric ceased accruing for this storm reserve as a result of the 2013 rate case settlement. However, in the event of a named storm that results in damage to its system, Tampa Electric can petition the FPSC to seek recovery of those costs over a 12-month period or longer as determined by the ~~FPSC.~~FPSC, as well as replenish its reserve to $56 million, the level of the reserve as of October 31, 2013. As of December 31, 2016, the balance of the self-insured storm reserve was $56 million.

As a result of several named storms, including Tropical Storm Colin, Hurricane Hermine and Hurricane Matthew, Tampa Electric incurred $10 million of storm costs in 2016. In the first quarter of 2017, Tampa Electric applied the $10 million of storm costs to the storm reserve. This resulted in a storm reserve balance of $46 million as of March 31, 2017. Tampa Electric was impacted by Hurricane Irma in the third quarter of 2017 and has currently estimated the total incurred incremental cost of restoration to be approximately $70 million, of which $60 million was charged to the storm reserve, $4 million was charged to O&M expense, and $6 million was charged to capital expenditures. At September 30, 2017, the amount of $60 million charged to the storm reserve exceeded the $46 million balance by $14 million, which is ~~also subject~~currently recorded as a regulatory asset on the balance sheet. Based on an FPSC order, if the charges to ~~regulation~~the storm reserve exceed the account balance, the excess is to be carried as a regulatory asset. Tampa Electric expects to petition the FPSC in early 2018 for recovery of the storm costs in excess of the reserve as well as replenish the balance in

the reserve to the $56 million level that existed as of October 31, 2013 for a total of $70 million. See the Regulatory Assets and Liabilities table below.

On June 28, 2016, PGS filed its depreciation study with the FPSC seeking approval for new depreciation rates. After communications with the FPSC staff, on December 15, 2016, PGS and OPC filed a settlement with the FPSC agreeing to new depreciation rates that reduce annual depreciation expense by $16 million, accelerate the amortization of the regulatory asset associated with environmental remediation costs as described below, include obsolete plastic pipe replacements through the existing cast iron and bare steel replacement rider, and decrease the bottom of the ROE range from 9.75% to 9.25%. The settlement agreement provided that the bottom of the ROE range will remain until the earlier of new base rates established in PGS’s next general base rate proceeding or December 31, 2020. The top of the ROE range will continue to be 11.75%, and the ROE of 10.75% will continue to be used for the calculation of return on investment for clauses and riders. On February 7, 2017, the FPSC approved the settlement agreement. No change in customer rates resulted from this agreement.

As part of the settlement, PGS and OPC agreed that at least $32 million of PGS’s regulatory asset associated with the environmental liability for current and future remediation costs related to former MGP sites, to the extent expenses are reasonably and prudently incurred, will be amortized over the period 2016 through 2020. At least $21 million will be amortized over a two-year recovery period beginning in 2016. In 2016, PGS recorded $16 million of this amortization expense. This additional amortization expense in 2016 was offset by the ~~FERC. The FPSC has jurisdiction over rates, service, issuance~~decrease in depreciation expense as discussed above with no impact to 2016 earnings. For the three and nine months ended September 30, 2017, PGS recorded amortization expense of ~~securities, safety, accounting~~$1 million and depreciation practices and other matters. In general, the FPSC sets rates based on a cost of service methodology which allows utilities to collect total revenues (revenue requirement) equal to their cost of providing service, plus a reasonable return on invested capital.$4 million, respectively.

NMGC is subject to regulation by the NMPRC. The NMPRC has jurisdiction over the regulatory matters related, directly and indirectly, to NMGC providing service to its customers, including, among other things, rates, accounting procedures, securities issuances, and standards of service. NMGC must follow certain accounting guidance that pertains specifically to entities that are subject to such regulation. Comparable to the FPSC, the NMPRC sets rates at a level that allows utilities to collect total revenues (revenue requirement) equal to their cost of providing service, plus a reasonable return on invested capital.

Tampa Electric ~~PGS~~ and ~~NMGC~~PGS apply the FASB’s accounting standards for regulated operations. Areas of applicability include: ~~deferral of revenues under approved regulatory agreements;~~ revenue recognition resulting from cost-recovery clauses that provide for monthly billing charges to reflect increases or decreases in fuel, purchased power, conservation and environmental costs; the deferral of costs as regulatory assets to the period in which the regulatory agency recognizes them when cost recovery is ordered over a period longer than a fiscal year; and the advance recovery of expenditures for approved costs such as future storm ~~damage~~restoration or the future removal of property. ~~All regulatory assets are recovered through the regulatory process.~~

The effective tax rates for the three months ended Sept. 30, 2016 and 2015 were 19.86% and 39.12%, respectively. The effective tax rate decreased to 34.19% for the nine months ended Sept. 30, 2016 from 39.10% for the same period in 2015.

The decrease in the three-month effective tax rate of 19.26% in 2016 versus the same period in 2015 is primarily due to tax benefits recorded in the third quarter of 2016 for federal R&D credits, lower non-deductible Merger transaction costs and other permanent book-to-tax differences.

The effective tax rate for year-to-date 2016 differed from the U.S. statutory rate of 35% primarily due to the effects of federal R&D credits and the tax benefit related to long-term incentive compensation offset by non-deductible Merger transaction costs (see ~~Notes 2 and 14~~ for further description). The effective tax rate for year-to-date 2015 differed from the U.S. statutory rate primarily due to tax expense related to long-term incentive compensation shares that vested below target levels.

TEC’s effective tax rates for the three months ended September 30, 2017 and 2016 were 38.73% and 32.53%, respectively. TEC’s effective tax rates for the nine months ended September 30, 2017 and 2016 were 38.61% and 34.59%, respectively. The increase in the three-month and nine-month effective tax rates in 2017 versus the same period in 2016 is primarily due to ~~four years~~lower AFUDC-equity, production deduction and R&D tax credit tax benefits.

TEC’s portion of the net periodic benefit cost for the three months ended September 30, 2017 and 2016, respectively, was $3 million and $4 million for pension benefits, and $1 million and $2 million for other postretirement benefits. TEC’s portion of the net periodic benefit cost for the nine months ended September 30, 2017 and 2016, respectively, was $10 million for each period for pension benefits, and $4 million and $5 million for other postretirement benefits.

For ~~the Jan. 1, 2016 measurement,~~2017, TECO Energy ~~used an~~ assumed a long-term EROA of 7.00% and a discount rate of ~~4.685%~~4.16% for pension benefits under its qualified pension plan. For the ~~Jan.~~January 1, ~~2016~~2017 measurement of TECO Energy’s other postretirement benefits, TECO Energy ~~assumed~~used a discount rate of ~~4.667% for the Florida-based plan and 4.687% for the NMGC plan.~~

As a result of the Merger, TECO Energy remeasured its employee postretirement benefit plans on the Merger effective date, July 1, 2016. As part of the remeasurement, TECO Energy used an above-mean yield curve to determine its discount rate. The above-mean yield curve technique matches the yields from high-quality (AA-rated, non-callable) corporate bonds to the company’s projected cash flows for the plans to develop a present value that is converted to a discount rate assumption, which is subject to change each year. TECO Energy previously used a bond model matching technique to determine its discount rate. The change in discount rate resulting from the different methodology used to select a discount rate did not have a material impact on the company’s financial statements and provides consistency with Emera’s method for selecting a discount rate. For the July 1, 2016 measurement, TECO Energy used an assumed long-term EROA of 7.00% and a discount rate of 3.72% for pension benefits under its qualified pension plan. For the July 1, 2016 measurement of TECO Energy’s other postretirement benefits, TECO Energy assumed a discount rate of 3.85%4.28%.

As a result of the remeasurement, TECO Energy’s net periodic benefit expense increased by $0.6 million for pension benefits and zero for other postretirement benefits for the three- and nine-months ended Sept. 30, 2016. TECO Energy’s liability for pension benefits increased by $61.7 million and $17.6 million for other postretirement benefits. The associated regulatory asset increased $54.0 million for pension benefits and $14.1 million for other postretirement benefits. Accumulated other comprehensive income decreased $7.7 million for pension benefits and $3.5 million for other postretirement benefits.

TECO Energy made contributions of ~~$37.4~~$46 million and ~~$55.0~~$37 million to its qualified pension plan ~~for~~in the nine months ended ~~Sept.~~September 30, 2017 and 2016, respectively. TEC’s portion of these contributions was $36 million and ~~2015,~~$31 million, respectively. ~~Additionally, NMGC made contributions of $2.7 million to its other postretirement benefits plan~~

Included in the benefit cost discussed above, for ~~the nine months ended Sept. 30, 2016 and 2015.~~

~~For~~ the three and nine months ended ~~Sept.~~September 30, ~~2016, TECO Energy and its subsidiaries~~2017, TEC reclassified ~~$0.8~~$3 million and ~~$1.8~~$8 million, respectively, of ~~pretax~~ unamortized prior service ~~benefit~~benefits and costs and actuarial gains and losses from ~~AOCI~~regulatory assets to net income, ~~as part of periodic benefit expense,~~ compared with ~~$0.2~~$3 million and ~~$2.4~~$8 million for the three and nine months ended ~~Sept. 30, 2015, respectively. In addition, during the three and nine months ended Sept.~~September 30, 2016, the regulated companies reclassified $3.8 million and $9.1 million, respectively, of unamortized prior service benefit and actuarial losses from regulatory assets to net income as part of periodic benefit expense, compared with $2.6 million and $7.8 million for the three and nine months ended Sept. 30, 2015, respectively.

The settlement cost recognized relates to the settlement of the SERP liability for the TECO Coal participants. An estimated curtailment loss for the SERP of $1.3 million was recognized in the second quarter of 2016 as a result of retirements expected in the third quarter of 2016 as a result of the Merger, which expected retirements occurred in the third quarter of 2016.

The company’s postretirement benefit plans were not explicitly impacted by the Merger. However, TECO Energy expects to recognize a settlement charge related to the SERP of approximately $8.0 million in the first quarter of 2017 due to retirements that have occurred as a result of the Merger.

At ~~Sept.~~September 30, ~~2016,~~2017, these credit facilities required commitment fees ranging from 12.5 to 30.0 basis points. The weighted-average interest rate on outstanding amounts payable under the credit facilities at ~~Sept.~~September 30, 2017 and December 31, 2016 was 2.07% and ~~Dec. 31, 2015 was 1.71% and 1.29%~~1.49%, respectively.

On ~~Mar. 14, 2016, TECO Finance~~March 22, 2017, TEC amended its $325 million bank credit facility, entering into a Fifth Amended and Restated Credit Agreement. The amendment (i) extended the maturity date of the credit facility from December 17, 2018 to March 22, 2022 (subject to further extension with the consent of each lender); (ii) included a $50 million letter of credit facility; and (iii) made other technical changes.

On November 2, 2017, TEC entered into a ~~one-year, $400~~364-day, $300 million credit ~~agreement. The credit~~ agreement ~~(i) has~~with a maturity date of ~~Mar. 14, 2017; (ii)~~November 1, 2018.

At ~~Sept.~~September 30, ~~2016,~~2017, TEC’s total long-term debt had a carrying amount of ~~$3,490.3~~$2,163 million and an estimated fair market value of ~~$3,911.2~~$2,377 million. At ~~Dec.~~December 31, ~~2015,~~2016, TEC’s total long-term debt had a carrying amount of ~~$3,822.5~~$2,163 million and an estimated fair market value of ~~$4,061.6~~$2,345 million. ~~The company~~TEC uses the market approach in determining fair value. The majority of the outstanding debt is valued using real-time financial market ~~data obtained from Bloomberg Professional Service.~~data. The remaining securities are valued using prices

obtained from the Municipal Securities Rulemaking Board or by applying estimated credit spreads obtained from a third party to the par value of the security. The fair value of debt securities ~~totaling $58.3 million is~~ determined using Level 1 ~~measurements; the~~measurements was $56 million and $58 million at September 30, 2017 and December 31, 2016, respectively. The fair value of the remaining debt securities is determined using Level 2 measurements (see Note 11 for information regarding the fair value hierarchy).

On Mar. 19, 2008, the HCIDA remarketed $86.0 million HCIDA Pollution Control Revenue Refunding Bonds, Series 2006 (Non-AMT) (the Series 2006 HCIDA Bonds) in a term rate mode pursuant to the terms of the Loan and Trust Agreement governing those bonds. The Series 2006 HCIDA Bonds bore interest at a term rate of 5.00% per annum from Mar. 19, 2008 to Mar. 15, 2012. On Mar. 15, 2012, TEC purchased in lieu of redemption the Series 2006 HCIDA Bonds. The Series 2006 HCIDA Bonds bore interest at a term rate of 1.875% per annum from Mar. 15, 2012 to Mar. 15, 2016. On Mar. 15, 2016, pursuant to the terms of the Loan and Trust Agreement governing the Series 2006 HCIDA Bonds, a mandatory tender occurred and a term rate of 2.00% per annum will apply from Mar. 15, 2016 to Mar. 15, 2020. The 2016 mandatory tender did not impact the Consolidated Condensed Balance Sheet. TEC is responsible for payment of the interest and principal associated with the Series 2006 HCIDA Bonds. Regularly scheduled principal and interest when due, are insured by Ambac Assurance Corporation.

As of Sept. 30, 2016, $232.6 million of bonds purchased in lieu of redemption, including the Series 2006 HCIDA Bonds described above, were held by the trustee at the direction of TEC to provide an opportunity to evaluate refinancing alternatives.

From time to time, ~~TECO Energy~~TEC and its subsidiaries are involved in various legal, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies in the ordinary course of its business. Where appropriate, accruals are made in accordance with accounting standards for contingencies to provide for matters that are probable of resulting in an estimable loss. ~~The company~~TEC believes the ~~claims in which the company or a subsidiary~~final disposition of ~~the company is a defendant in the pending actions described below are without merit and intends to defend the matters vigorously.~~

In November 2010, heavy equipment operated at a road construction site being conducted by Posen Construction, Inc. struck a natural gas line causing a rupture and ignition of the gas and an outage in the natural gas service to Lee and Collier counties, Florida. PGS filed suit in April 2011 against Posen Construction, Inc. in Federal Court for the Middle District of Florida to recover damages for repair and restoration relating to the incident and Posen Construction, Inc. counter-claimed against PGS alleging negligence. In the first quarter of 2014, the parties entered into a settlement agreement that resolves the claims of the parties. In addition, a suit was filed in November 2011 by the Posen Construction, Inc. employee operating the heavy equipment involved in the incident in Lee County Circuit Court against PGS and a PGS contractor involved in the project, seeking damages for his injuries. The suit against PGS remains pending, with a trial currently expected in February 2017. The company is unable at this time to estimate the possible loss or range of loss with respect to this matter. While the outcome of such proceeding is uncertain, management doesthese proceedings will not ~~believe that its ultimate resolution will~~ have a material ~~adverse~~ effect on ~~the company’s~~its results of operations, cash flows or financial ~~condition or cash flows.~~position.

In February 2011, NMGC experienced gas shortages due to weather-related interruptions of electric service, weather-related problems on the systems of various interstate pipelines and in gas fields that are the sources of gas supplied to NMGC, and high weather-driven usage. This gas supply disruption and high usage resulted in the declaration of system emergencies by NMGC causing involuntary curtailments of gas utility service to approximately 28,700 customers (residential and business).

In March 2011, a customer purporting to represent a class consisting of all “32,000 [sic] customers” who had their gas utility service curtailed during the early-February system emergencies filed a putative class action lawsuit against NMGC. In March 2011, the Town of Bernalillo, New Mexico, purporting to represent a class consisting of all “New Mexico municipalities and governmental entities who have suffered damages as a result of the natural gas utility shut off” also filed a putative class action lawsuit against NMGC, four of its officers, and John and Jane Does at NMGC. In July 2011, the plaintiff in the Bernalillo class action filed an amended complaint to add an additional plaintiff purporting to represent a class of all “similarly situated New Mexico private businesses and enterprises.”

~~In September 2015, a settlement was reached with all the named plaintiff class representatives in both of the class actions. The settlements were on an individual basis and not a class basis.~~

~~In addition to the two settled class actions described above, 18 insurance carriers have filed two subrogation lawsuits for monies~~

paid to their insureds as a result of the curtailment of natural gas service in February 2011. In January 2016, the judge entered summary judgment in favor of NMGC and all of the subrogation lawsuits were dismissed. The insurance carriers subsequently filed a timely appeal of the summary judgment. In late May 2016, a settlement was reached with all the named plaintiffs in the subrogation lawsuits. A motion to dismiss the appeal was granted by the court on Aug. 2, 2016.

Twelve securities class action lawsuits were filed against the company and its directors by holders of TECO Energy securities following the announcement of the Emera transaction. Eleven suits were filed in the Circuit Court for the 13th Judicial Circuit, in and for Hillsborough County, Florida. They alleged that TECO Energy’s board of directors breached its fiduciary duties in agreeing to the Merger Agreement and sought to enjoin the Merger. Several of these suits alleged that one or more of TECO Energy, Emera and an Emera affiliate aided and abetted such alleged breaches. The securities class action lawsuits were consolidated per court order. Since the consolidation, two of the complaints were amended. One of those complaints has added a claim against the individual defendants for breach of fiduciary duty to disclose. The twelfth suit was filed in the Middle District of Florida Federal Court and has subsequently been voluntarily dismissed.

The company also received two separate shareholder demand letters from purported shareholders of the company. Both of these letters demanded that the company maximize shareholder value and remove alleged conflicts of interest as well as eliminate allegedly preclusive deal protection devices. One of the letters also demanded that the company refrain from consummating the transaction with Emera. Both of these demand letters have subsequently been withdrawn.

In November 2015, the parties to the lawsuits entered into a Memorandum of Understanding with the various shareholder plaintiffs to settle, subject to court approval, all of the pending shareholder lawsuits challenging the proposed Merger. As a result of the Memorandum of Understanding, the company made additional disclosures related to the proposed Merger in a proxy supplement.

In September 2016, a hearing was held to gain preliminary approval of a negotiated stipulation of settlement. After that hearing, the judge entered an order granting preliminary approval of the class action settlement and scheduling a final approval hearing for December 2016.

There can be no assurance that the court will grant final approval of the settlement. However, while the outcome of such proceeding remains uncertain, management does not believe that its ultimate resolution will have a material adverse effect on the company’s results of operations, financial condition or cash flows.

~~As discussed in~~ ~~Note 15~~, TECO Coal was sold on Sept. 21, 2015 to Cambrian. On Mar. 18, 2016, Cambrian delivered a notice of a purported claim to TECO Diversified asserting breach of certain representations, and fraud and willful misconduct in connection therewith, of the SPA. While the outcome of such matter is uncertain, management does not believe that its ultimate resolution will have a material adverse effect on the company’s results of operations, financial condition or cash flows.

On Dec. 19, 2013, the ICSID Tribunal hearing the arbitration claim of TGH, a wholly owned subsidiary of TECO Energy, against the Republic of Guatemala (Guatemala) under the DR – CAFTA, issued an award in the case (the Award). The ICSID Tribunal unanimously found in favor of TGH and awarded damages to TGH of approximately U.S. $21.1 million, plus interest from Oct. 21, 2010 at a rate equal to the U.S. prime rate plus 2%. In addition, the ICSID Tribunal ruled that Guatemala must reimburse TGH for approximately U.S. $7.5 million of the costs that it incurred in pursuing the arbitration.

~~On Apr. 18, 2014, Guatemala filed an application for annulment of the entire Award (or, alternatively, certain parts of the Award) pursuant to applicable ICSID rules.~~

Also on Apr. 18, 2014, TGH separately filed an application for partial annulment of the Award on the basis of certain deficiencies in the ICSID Tribunal’s determination of the amount of TGH’s damages.

On Apr. 5, 2016, an ICSID ad hoc Committee issued a decision in favor of TGH in the annulment proceedings. In its decision, the ad hoc Committee unanimously dismissed Guatemala’s application for annulment of the award and upheld the original $21.1 million award, plus interest. In addition, the ad hoc Committee granted TGH’s application for partial annulment of the award, and ordered Guatemala to pay certain costs relating to the annulment proceedings. Because the Tribunal’s award of costs to TGH in its original arbitration was based on the Tribunal’s assessment that TGH had prevailed on liability and Guatemala had partially prevailed on damages, and the latter finding was annulled by the ad hoc Committee, the Committee also annulled the Tribunal’s award of costs to TGH. As a result, TGH had the right to resubmit its arbitration claim against Guatemala to seek additional damages (in addition to the previously awarded $21.1 million), as well as additional interest on the $21.1 million, and its full costs relating to the original arbitration and the new arbitration proceeding. Results to date do not reflect any benefit of this decision.

On Sept. 23, 2016, TGH filed a request for resubmission to arbitration. On Oct. 3, 2016, ICSID issued a notice of registration for TGH’s request for resubmission, officially commencing the new arbitration and starting the time periods for constitution of the new tribunal.

TEC, through its Tampa Electric and ~~Peoples Gas~~PGS divisions, is a PRP for certain superfund sites and, through its ~~Peoples Gas~~PGS division, for certain former ~~manufactured gas plant~~MGP sites. While the joint and several liability associated with these sites presents the potential for significant response costs, as of ~~Sept.~~September 30, ~~2016,~~2017, TEC has estimated its ultimate financial liability to be ~~$33.9~~$30 million, primarily at PGS. This amount

has been accrued and is primarily reflected in the long-term liability section under “Deferred credits and other liabilities” on the Consolidated Condensed Balance Sheets. The environmental remediation costs associated with these sites ~~which~~ are expected to be paid over many ~~years, are not expected to have a significant impact on customer rates.~~years.

The estimated amounts represent only the portion of the cleanup costs attributable to TEC. The estimates to perform the work are based on TEC’s experience with similar work, adjusted for site-specific conditions and agreements with the respective governmental agencies. The estimates are made in current dollars, are not discounted and do not assume any insurance recoveries.

In instances where other PRPs are involved, most of those PRPs are creditworthy and are likely to continue to be creditworthy for the duration of the remediation work. However, in those instances that they are not, TEC could be liable for more than TEC’s ~~actual~~currently assessed percentage of the remediation costs.

Factors that could impact these estimates include the ability of other PRPs to pay their pro-rata portion of the cleanup costs, additional testing and investigation which could expand the scope of the cleanup activities, additional liability that might arise from the cleanup activities themselves or changes in laws or regulations that could require additional remediation. Under current regulations, these costs are recoverable through customer rates established in subsequent base rate proceedings.

~~In connection with the Merger with Emera, TECO Energy made certain commitments approved by the NMPRC.~~ See Note 14 ~~for additional information.~~

~~A summary of the face amount or maximum theoretical obligation and the year of expiration under guarantees as of Sept. 30, 2016 is as follows:~~

TECO Energy and its subsidiaries must meet certain financial tests, including a debt to capital ratio, as defined in the applicable banking agreements. TECO Energy and its subsidiaries have certain restrictive covenants in specific agreements and debt instruments. At Sept. 30, 2016, TECO Energy and its subsidiaries were in compliance with all applicable financial covenants.

TECO Energy is an electric and gas utility holding company with diversified activities. Segments are determined based on how management evaluates, measures and makes decisions with respect to the operations of the entity. The management of TECO Energy reports segments based on each subsidiary’s contribution of revenues, net income and total assets as required by the accounting guidance for disclosures about segments of an enterprise and related information. Intercompany transactions are eliminated in the Consolidated Condensed Financial Statements of TECO Energy, but are included in determining reportable segments.

~~From time to time, TECO Energy and its affiliates enter into futures, forwards, swaps and option contracts for the following purposes:~~

TECO Energy and its affiliates use derivatives only to reduce normal operating and market risks, not for speculative purposes. The regulated utilities’ primary objective in using derivative instruments for regulated operations is to reduce the impact of market price volatility on ratepayers.

The risk management policies adopted by TECO Energy provide a framework through which management monitors various risk exposures. Daily and periodic reporting of positions and other relevant metrics are performed by a centralized risk management group, which is independent of all operating companies.

The company applies the accounting standards for derivative instruments and hedging activities. These standards require companies to recognize derivatives as either assets or liabilities in the financial statements, to measure those instruments at fair value and to reflect the changes in the fair value of those instruments as either components of OCI or in net income, depending on the designation of those instruments (see ~~Note 11~~). The changes in fair value that are recorded in OCI are not immediately recognized in current net income. As the underlying hedged transaction matures or the physical commodity is delivered, the deferred gain or loss on the related hedging instrument must be reclassified from OCI to earnings based on its value at the time of the instrument’s settlement. For effective hedge transactions, the amount reclassified from OCI to earnings is offset in net income by the market change of the amount paid or received on the underlying physical transaction.

The company applies the accounting standards for regulated operations to financial instruments used to hedge the purchase and sale of natural gas for the benefit of its regulated companies’ ratepayers. These standards, in accordance with the FPSC and NMPRC, permit the changes in fair value of natural gas derivatives to be recorded as regulatory assets or liabilities reflecting the impact of hedging activities on the fuel recovery clause. As a result, these changes are not recorded in OCI (see ~~Note~~ 3).

The company’s physical contracts qualify for the NPNS exception to derivative accounting rules, provided they meet certain criteria. Generally, NPNS applies if the company deems the counterparty creditworthy, if the counterparty owns or controls resources within the proximity to allow for physical delivery of the commodity, if the company intends to receive physical delivery and if the transaction is reasonable in relation to the company’s business needs. As of Sept. 30, 2016, all of the company’s physical contracts qualify for the NPNS exception with the exception of a minor amount of forward purchases and sales entered into by NMGC to optimize its gas storage capacity.

The derivatives that are designated as cash flow hedges at Sept. 30, 2016 and Dec. 31, 2015 are reflected on the company’s Consolidated Condensed Balance Sheets and classified accordingly as current and long-term assets and liabilities on a net basis as permitted by their respective master netting agreements. Derivative assets totaled $2.2 million and $0.2 million as of Sept. 30, 2016 and Dec. 31, 2015, respectively. Derivative liabilities totaled $1.7 million and $26.2 million as of Sept. 30, 2016 and Dec. 31, 2015, respectively. There are minor offset amount differences between the gross derivative assets and liabilities and the net amounts included in the Consolidated Condensed Balance Sheets. There was no cash collateral posted with or received from any counterparties.

All of the derivative assets and liabilities at Sept. 30, 2016 and Dec. 31, 2015 are designated as hedging instruments, which primarily are derivative hedges of natural gas contracts to limit the exposure to changes in market price for natural gas used to produce energy and natural gas purchased for resale to customers. The corresponding effect of these natural gas related derivatives on the regulated utilities’ fuel recovery clause mechanism is reflected on the Consolidated Condensed Balance Sheets as current and long-term regulatory assets and liabilities. Based on the fair value of the instruments at Sept. 30, 2016, net pretax gains of $0.5 million are expected to be reclassified from regulatory assets or liabilities to the Consolidated Condensed Statements of Income within the next twelve months.

~~The Sept. 30, 2016 and Dec. 31, 2015 balance in AOCI related to the cash flow hedges and interest rate swaps (unsettled and previously settled) is presented in~~ ~~Note 12~~.

~~earnings for the three and nine months ended Sept. 30, 2016 and 2015 is presented in~~ ~~Note 12. These gains and losses were the result of interest rate contracts for TEC. The location of the reclassification to income was reflected in “Interest expense” for TEC.~~

The maximum length of time over which the company is hedging its exposure to the variability in future cash flows extends to Sept. 30, 2018 for financial natural gas contracts. The following table presents the company’s derivative volumes that, as of Sept. 30, 2016, are expected to settle during the 2016, 2017 and 2018 fiscal years:

The company is exposed to credit risk by entering into derivative instruments with counterparties to limit its exposure to the commodity price fluctuations associated with natural gas. Credit risk is the potential loss resulting from a counterparty’s nonperformance under an agreement. The company manages credit risk with policies and procedures for, among other things, counterparty analysis, exposure measurement and exposure monitoring and mitigation.

It is possible that volatility in commodity prices could cause the company to have material credit risk exposures with one or more counterparties. If such counterparties fail to perform their obligations under one or more agreements, the company could suffer a material financial loss. However, as of Sept. 30, 2016, substantially all of the counterparties with transaction amounts outstanding in the company’s energy portfolio were rated investment grade by the major rating agencies. The company assesses credit risk internally for counterparties that are not rated.

The company has entered into commodity master arrangements with its counterparties to mitigate credit exposure to those counterparties. The company generally enters into the following master arrangements: (1) EEI agreements—standardized power sales contracts in the electric industry; (2) ISDA agreements—standardized financial gas and electric contracts; and (3) NAESB agreements—standardized physical gas contracts. The company believes that entering into such agreements reduces the risk from default by creating contractual rights relating to creditworthiness, collateral and termination.

The company has implemented procedures to monitor the creditworthiness of its counterparties and to consider nonperformance risk in determining the fair value of counterparty positions. Net liability positions generally do not require a nonperformance risk adjustment as the company uses derivative transactions as hedges and has the ability and intent to perform under each of these contracts. In the instance of net asset positions, the company considers general market conditions and the observable financial health and outlook of specific counterparties in evaluating the potential impact of nonperformance risk to derivative positions.

Certain TECO Energy derivative instruments contain provisions that require the company’s debt, or in the case of derivative instruments where TEC is the counterparty, TEC’s debt, to maintain an investment grade credit rating from any or all of the major credit rating agencies. If debt ratings, including TEC’s, were to fall below investment grade, it could trigger these provisions, and the counterparties to the derivative instruments could demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions. The company has no other contingent risk features associated with any derivative instruments.

Accounting guidance governing fair value measurements and disclosures provides that fair value represents the amount that would be received in selling an asset or the amount that would be paid in transferring a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based upon assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, accounting guidance also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

~~Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and~~

~~Level 3: Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.~~

~~Assets and liabilities are measured at fair value based on one or more of the following three valuation techniques noted under accounting guidance:~~

~~(A)~~ ~~Market approach: Prices and other relevant information generated by market transactions involving~~

~~(B)~~ ~~Cost approach~~: ~~Amount that would be required to replace the service capacity of an asset (replacement~~

~~(C)~~ ~~Income approach~~: ~~Techniques to convert future amounts to a single present amount based upon market~~

~~expectations (including present value techniques, option-pricing and excess earnings models).~~

~~The fair value of financial instruments is determined by using various market data and other valuation techniques.~~

The following tables set forth by level within the fair value hierarchy, the company’s financial assets and liabilities that were accounted for at fair value on a recurring basis. As required by accounting standards for fair value measurements, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

The natural gas derivatives are OTC swap, forward and option instruments. Fair values of swaps and forwards are estimated utilizing the market approach. The price of swaps and forwards are calculated using observable NYMEX quoted closing prices of exchange-traded futures. Fair values of options are estimated utilizing the income approach. The price of options is calculated using the Black-Scholes model with observable exchange-traded futures as the primary pricing inputs to the model. Additional inputs to the model include historical volatility, discount rate, and a locational basis adjustment to NYMEX. The resulting prices are applied to the notional quantities of active swap, forward and option positions to determine the fair value (see ~~Note 10~~).

The company considered the impact of nonperformance risk in determining the fair value of derivatives. The company considered the net position with each counterparty, past performance of both parties, the intent of the parties, indications of credit deterioration and whether the markets in which the company transacts have experienced dislocation. At Sept. 30, 2016, the fair value of derivatives was not materially affected by nonperformance risk. There were no Level 3 assets or liabilities for the periods presented.

As of Sept. 30, 2016 and Dec. 31, 2015, the carrying value of the company’s short-term debt is not materially different from the fair value due to the short-term nature of the instruments and because the stated rates approximate market rates. The fair value is determined using Level 2 measurements. See ~~Note 7~~ ~~for information regarding the fair value of the company’s long-term debt.~~

TECO Energy reported the following OCI related to changes in the fair value of cash flow hedges, recognized cost due to curtailment, change in benefit obligation due to remeasurement and amortization of unrecognized benefit costs associated with the company’s postretirement plans:

The determination of a VIE’s primary beneficiary is the enterprise that has both 1) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and 2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE.

Tampa Electric has entered into multiple PPAs with wholesale energy providers in Florida to ensure the ability to meet customer energy demand and to provide lower cost options in the meeting of this demand. These agreements range in size from 117 MW to 250 MW of available capacity, are with similar entities and contain similar provisions. Because some of these provisions provide for the transfer or sharing of a number of risks inherent in the generation of energy, these agreements meet the definition of being variable interests. These risks include: operating and maintenance, regulatory, credit, commodity/fuel and energy market risk. Tampa Electric has reviewed these risks and has determined that the owners of these entities have retained the majority of these risks over the expected life of the underlying generating assets, have the power to direct the most significant activities, and have the obligation or right to absorb losses or benefits. As a result, Tampa Electric is not the primary beneficiary and is not required to consolidate any of these entities. Tampa Electric purchased $19.1 million and $48.1 million under these PPAs for the three and nine months ended Sept. 30, 2016, respectively, and $10.7 million and $26.0 million for the three and nine months ended Sept. 30, 2015, respectively.

The company does not provide any material financial or other support to any of the VIEs it is involved with, nor is the company under any obligation to absorb losses associated with these VIEs. In the normal course of business, the company’s involvement with these VIEs does not affect its Consolidated Condensed Balance Sheets, Statements of Income or Cash Flows.

Pursuant to the Merger Agreement, upon the closing of the Merger, each issued and outstanding share of TECO Energy common stock was cancelled and converted automatically into the right to receive $27.55 in cash, without interest (Merger Consideration). This represents an aggregate purchase price of approximately $10.7 billion including Emera’s purchase price allocation for debt of approximately $4.2 billion.

On Apr. 11, 2016, Emera and TECO Energy filed with the NMPRC an unopposed stipulation agreement reflecting a settlement reached with certain intervening parties in the then pending proceeding seeking the approval of the Merger by the NMPRC. On May 2, 2016, the Hearing Examiner held a hearing to consider the stipulation agreement. On June 8, 2016, the Hearing Examiner filed a Certificate of Stipulation, recommending approval by the NMPRC of the stipulation with respect to which all intervenors had either consented or filed a notice of non-opposition. On June 22, 2016, the NMPRC approved the stipulation, and an order was entered on that same day.

~~As part of the stipulation agreement filed with the NMPRC, upon closing of the Merger, NMGC agreed, among other things, to:~~

The company recorded the pretax costs of $30.4 million (or approximately $17.7 million after tax) related to these commitments in the three months ended Sept. 30, 2016. The bill credit of $8.0 million was recognized as a reduction in “Regulated gas revenues” and the remaining items recorded in “Merger transaction-related costs” on the Consolidated Condensed Statements of Income for the three and nine months ended Sept. 30, 2016. As of Sept. 30, 2016, approximately $30 million remains to be paid and is included in “Other” in cash flows from operating activities in the Consolidated Condensed Statements of Cash Flows for the nine months ended Sept. 30, 2016.

In addition to the Merger-related regulatory matters above, during the three and nine months ended Sept. 30, 2016, TECO Energy also incurred approximately $15.5 million and $87.0 million, respectively, of pretax transaction-related costs ($9.6 million and $68.1 million after tax, respectively), compared with approximately $15.4 million of pretax transaction-related costs during the three and nine months ended Sept. 30, 2015. These costs are presented in “Merger transaction-related costs” on the Consolidated Condensed Statements of Income.

For the three months ended Sept. 30, 2016, the $15.5 million of costs are primarily for accelerated vesting of outstanding stock-based compensation awards in accordance with the Merger Agreement and other employee-related costs. For the nine months ended Sept. 30, 2016, the costs also include $27.7 million of investment banking, legal and other consultant costs, $42.4 million for change-in-control and other compensation payments, and $1.3 million for a non-cash SERP curtailment charge recorded in the second quarter. During the third quarter of 2016, Emera contributed $22 million to TECO Energy primarily related to funding accelerated stock compensation payments. Transaction-related costs expensed and paid through Sept. 30, 2016 have been reflected in cash flows from operating activities in the Consolidated Condensed Statements of Cash Flows for the nine months ended Sept. 30, 2016. As of Sept. 30, 2016, approximately $20 million remains to be paid. These remaining costs are expected to be paid primarily in the first quarter of 2017 and are included in “Accounts payable” in cash flows from operating activities in the Consolidated Condensed Statements of Cash Flows for the nine months ended Sept. 30, 2016.

~~See~~ ~~Notes 4 and 5~~ for information regarding ~~impacts to the company’s taxes and employee postretirement benefits, respectively, as a result of the Merger.~~

On June 22, 2016, in accordance with the Merger Agreement, the TECO Energy board of directors declared a special pro-rated dividend at the then-current rate of $0.002527 per share per day that accrued from May 16, 2016 (the prior TECO Energy dividend record date) until and including June 30, 2016 (the day prior to the effective date of the Merger). This dividend was accrued on the company’s Consolidated Condensed Balance Sheet as of June 30, 2016. On July 12, 2016, TECO Energy paid this dividend of $26.8 million to shareholders of record as of the close of business on the last trading day prior to the effective date of the Merger.

~~On Sept. 21, 2015, TECO Energy’s subsidiary, TECO Diversified, entered into~~ an SPA and completed the sale of all of its ownership interest in TECO Coal to Cambrian. The SPA did not provide for an up-front purchase payment, but provides for future contingent consideration of up to $60 million that may be paid yearly through 2019 if certain coal benchmark prices reach certain levels. The 2015 benchmark price was not reached and no contingent consideration payment was triggered. TECO Energy retains certain deferred tax assets and personnel-related liabilities, but all other TECO Coal assets and liabilities, including working capital, asset retirement obligations and workers compensation reserves, were transferred in the transaction. Letters of indemnity related to TECO Coal reclamation bonds will remain in effect until the bonds are replaced by Cambrian (see description of guarantees in ~~Note 8). The SPA contained customary representations, warranties and covenants (see~~ ~~Note 8~~ for description of a claim filed by Cambrian related to the SPA). The costs shown for 2016 in the table below reflects charges for personnel-related liabilities that remained with TECO Energy and legal costs associated with the claim related to the SPA.

Since the closing of the sale, TECO Energy has not had influence over operations of TECO Coal, therefore the contingent payments are not considered to meet the definition of direct cash flows under the applicable discontinued operations FASB guidance.

In 2012, TECO Guatemala completed the sale of its interests in the Alborada and San José power stations, and related solid fuel handling and port facilities in Guatemala. All periods presented reflect the classification of results from operations for TECO Guatemala and certain charges at Parent that directly relate to TECO Guatemala as discontinued operations. While TECO Energy and its subsidiaries no longer have assets or operations in Guatemala, its subsidiary, TECO Guatemala Holdings, LLC, has retained its rights under its arbitration claim filed against the Republic of Guatemala (see ~~Note 8). The charges shown in the table below are legal costs associated with that claim.~~

~~The accompanying notes are an integral part of the consolidated condensed financial statements.~~

~~See TEC’s 2015 Annual Report on Form 10-K for a complete discussion of accounting policies. The significant accounting policies for TEC include:~~

TEC is a wholly owned subsidiary of TECO Energy. For the purposes of its consolidated financial reporting, TEC is comprised of the electric division, referred to as Tampa Electric, and the natural gas division, referred to as PGS. For the periods presented, no VIEs have been consolidated (see ~~Note 13~~).

Intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, the unaudited consolidated condensed financial statements include all adjustments that are of a recurring nature and necessary to state fairly the financial position of TEC as of Sept. 30, 2016 and Dec. 31, 2015, and the results of operations and cash flows for the periods ended Sept. 30, 2016 and 2015. The results of operations for the three and nine months ended Sept. 30, 2016 are not necessarily indicative of the results that can be expected for the entire fiscal year ending Dec. 31, 2016.

On July 1, 2016, TECO Energy and Emera completed the Merger contemplated by the Merger Agreement entered into on Sept. 4, 2015. As a result of the Merger, the Merger Sub Company merged with and into TECO Energy with TECO Energy continuing as the surviving corporation and becoming a wholly owned indirect subsidiary of Emera. The acquisition method of accounting was not pushed down to TECO Energy or its subsidiaries, including TEC. See ~~Note 14~~ ~~for further information.~~

As of Sept. 30, 2016 and Dec. 31, 2015, unbilled revenues of $63.7 million and $53.7 million, respectively, are included in the “Receivables” line item on the Consolidated Condensed Balance Sheets.

~~Tampa Electric and PGS are allowed to recover certain costs from customers on a dollar-per-dollar basis through rates~~agreement approved by the ~~FPSC. The amounts included in customers’ bills~~FPSC to accelerate the amortization of the regulated asset associated with this liability.

TEC has commitments for ~~franchise fees~~purchased power and ~~gross receipt taxes are included as revenues on the Consolidated Condensed Statements of Income. Franchise fees~~long-term leases, primarily for land, building space, vehicles, office equipment, heavy equipment, other purchase obligations, long-term service agreements and ~~gross receipt taxes payable by Tampa Electric~~capital projects. In addition, TEC has payment obligations under contractual agreements for fuel, fuel transportation and PGS are included as an expense on the Consolidated Condensed Statements of Income in “Taxes, other than income”. These amounts totaled $32.6 million and $89.2 million for the three and nine months ended Sept. 30, 2016, respectively, and $31.7 million and $88.3 million for the three and nine months ended Sept. 30, 2015, respectively.

~~The new U.S. GAAP accounting policies~~power purchases that are ~~applicable to and were adopted by TEC are described as follows:~~

~~Interest – Imputation~~recovered from customers under regulatory clauses. The following is a schedule of ~~Interest~~

~~In April 2015, the FASB issued Accounting Standard Update (ASU) 2015-03,~~ ~~Interest – Imputation~~future payments under PPAs, minimum lease payments with non-cancelable lease terms in excess of ~~Interest~~, which simplifies the presentation of debt issuance costs. The amendments require debt issuance costs be presented on the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs is not affected. TEC adopted this standard in the first quarter of 2016, and Dec. 31, 2015 balances have been retrospectively restated. This change resulted in $18.1 million of debt issuance costs as of Dec. 31, 2015, previously presented as “Deferred chargesone year, and other assets”, being reclassified as a deduction from the carrying amount of the related “Long-term debt, less amount due within one year” line item on its Consolidated Condensed Balance Sheet. In accordance with ASU

~~2015-15~~ ~~Interest: Imputation of Interest~~, TEC continues to present debt issuance costs related to its letter of credit arrangements and related instruments in “Prepayments and other current assets” on its Consolidated Condensed Balance Sheets.

~~Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships~~

~~In March 2016, the FASB issued ASU 2016-05,~~ ~~Derivatives and Hedging Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.~~ The standard clarifies that a change in the counterparty to a derivative contract, in and of itself, does not require the dedesignation of a hedging relationship provided that all other hedge accounting criteria continue to be met. TEC early adopted in the third quarter of 2016 as permitted.

TEC considers the applicability and impact of all ASUs issued by FASB. The following updates have been issued by FASB but have not yet been adopted by TEC. Any ASUs not included below were assessed and determined to be either not applicable to TEC or are not expected to have a material impact on the consolidated financial statements.

~~In May 2014, the FASB issued ASU 2014-09,~~ ~~Revenue from Contracts with Customers~~, which creates a new principle-based revenue recognition framework. The core principle is that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to. The guidance will require additional disclosures regarding the nature, amount, timing and uncertainty of revenue arising from contracts with customers. This guidance will be effective beginning in 2018, with early adoption permitted in 2017, and will allow for either full retrospective adoption or modified retrospective adoption. TEC will adopt this guidance effective Jan. 1, 2018. TEC has developed an implementation plan and is continuing to evaluate the available adoption methods. While TEC does not expect the impact to be significant, it is continuing to evaluate the impact of adoption of this standard on its consolidated financial statements and disclosures.

~~Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities~~

~~In January 2016, the FASB issued ASU 2016-01,~~ ~~Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities.~~ The standard provides guidance for the recognition, measurement, presentation and disclosure of financial assets and liabilities. TEC does not have equity investments or available-for-sale debt securities and it does not record financial liabilities under the fair value option. However, it is evaluating the impact of the adoption of this guidance on its financial statement disclosures. This guidance will be effective for annual reporting periods, including interim reporting within those periods, beginning after Dec. 15, 2017.

~~In February 2016, the FASB issued ASU 2016-02,~~ ~~Leases.~~ The standard increases transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet for leases with terms of more than 12 months. Under the existing guidance, operating leases are not recorded as lease assets and lease liabilities on the balance sheet. The effect of leases on the Consolidated Statements of Income and the Consolidated Statements of Cash Flows is largely unchanged. The guidance will require additional disclosures regarding key information about leasing arrangements. This guidance is effective for annual reporting periods including interim reporting within those periods, beginning after Dec. 15, 2018. Early adoption is permitted, and is required to be applied using a modified retrospective approach. TEC is currently evaluating the impact of adoption of this standard on its consolidated financial statements.

~~In June 2016, the FASB issued ASU 2016-13,~~ ~~Measurement of Credit Losses on Financial Instruments. The standard provides guidance regarding the measurement of credit losses for financial assets and certain other instruments that are not accounted for~~net purchase obligations/commitments at fair value through net income, including trade and other receivables, debt securities, net investment in leases, and off-balance sheet credit exposures. The new guidance requires companies to replace the current incurred loss impairment methodology with a methodology that measures all expected credit losses for financial assets based on historical experience, current conditions, and reasonable and supportable forecasts. The guidance expands the disclosure requirements regarding credit losses, including the credit loss methodology and credit quality indicators. This guidance will be effective beginning in 2020, with early adoption permitted in 2019, and will be applied using a modified retrospective approach. TEC is currently evaluating the impact of adoption of this standard on its consolidated financial statements.

~~Classification of Certain Cash Receipts and Cash Payments on the Statement of Cash Flows~~

~~In August 2016, the FASB issued ASU 2016-15,~~ ~~Classification of Certain Cash Receipts and Cash Payments on the Statement of Cash Flows~~. The standard provides guidance regarding the classification of certain cash receipts and cash payments on the statement of cash flows, where specific guidance is provided for issues not previously addressed. This guidance will be effective for TEC beginning in 2018, with early adoption permitted, and is required to be applied on a retrospective approach. TEC is currently evaluating the impact of adoption of this standard on its consolidated statement of cash flows.

Tampa Electric’s retail business and PGS are regulated separately by the FPSC. Tampa Electric is also subject to regulation by the FERC. The FPSC has jurisdiction over rates, service, issuance of securities, safety, accounting and depreciation practices and other matters. In general, the FPSC sets rates based on a cost of service methodology which allows utilities to collect total revenues (revenue requirement) equal to their cost of providing service, plus a reasonable return on invested capital.

Tampa Electric and PGS apply the accounting standards for regulated operations. Areas of applicability include: deferral of revenues under approved regulatory agreements; revenue recognition resulting from cost-recovery clauses that provide for monthly billing charges to reflect increases or decreases in fuel, purchased power, conservation and environmental costs; the deferral of costs as regulatory assets to the period in which the regulatory agency recognizes them when cost recovery is ordered over a period longer than a fiscal year; and the advance recovery of expenditures for approved costs such as future storm damage or the future removal of property. All regulatory assets are recovered through the regulatory process.

~~Details of the regulatory assets and liabilities are presented in the following table:~~September 30, 2017:

Effective July 1, 2016 and due to the Merger with Emera, TEC is included in a consolidated U.S. federal income tax return with EUSHI and its subsidiaries. TEC’s income tax expense is based upon a separate return method, modified for the benefits-for-loss allocation in accordance with EUSHI’s tax sharing agreement. To the extent that TEC’s cash tax positions are settled differently than the amount reported as realized under the tax sharing agreement, the difference is accounted for as either a capital contribution or a distribution. Taxes accrued to affiliates was $14.2 million as of Sept. 30 2016.

TEC’s effective tax rates for the three months ended Sept. 30, 2016 and 2015 were 32.53% and 37.73%, respectively. The effective tax rates for the nine months ended Sept. 30, 2016 and 2015 were 34.59% and 37.15%, respectively. The decrease in the three-month effective tax rate of 5.2% in 2016 versus the same period in 2015 is primarily due to a tax benefit recorded in the third quarter of 2016 for federal R&D credits. TEC’s effective tax rates for the nine months ended Sept. 30, 2016 and 2015 differ from the statutory rate principally due to the tax benefit related to AFUDC-equity and federal R&D credits.

The IRS concluded its examination of TECO Energy’s 2014 consolidated federal income tax return in December 2015. The U.S. federal statute of limitations remains open for the year 2013 and forward. Years 2015 and the short tax year ending June 30, 2016 are currently under examination by the IRS under its Compliance Assurance Program (CAP). Due to the Merger with Emera, TECO Energy is only able to participate in the CAP through its short tax year ending June 30, 2016. Florida’s statute of limitations is three years from the filing of an income tax return. The state impact of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. Years still open to examination by Florida’s tax authorities include 2005 and forward as a result of TECO Energy’s consolidated Florida net operating loss still being utilized.

Authoritative guidance related to accounting for uncertainty in income taxes require an enterprise to recognize in its financial statements the best estimate of the impact of a tax position by determining if the weight of the available evidence indicates that it is more likely than not, based solely on the technical merits, that the position will be sustained upon examination, including resolution of any related appeals and litigation processes. As of Sept. 30, 2016 and Dec. 31, 2015, TEC’s uncertain tax positions were $6.5 million and zero, respectively, all of which was recorded as a reduction of deferred income tax assets for tax credit carryforwards. The increase was due to an uncertain tax position related to federal R&D tax credits. TEC believes that the total unrecognized tax benefits will decrease within the next twelve months due to the expected audit examination of TECO Energy’s consolidated federal income tax return for the short tax year ending June 30, 2016. As of Sept. 30, 2016, if recognized, $6.5 million of the unrecognized tax benefits would reduce TEC’s effective tax rate.

~~TEC is a participant in the comprehensive retirement plans of TECO Energy. Amounts allocable to all participants of the TECO Energy retirement plans are found in~~ ~~Note 5~~, ~~Employee Postretirement Benefits, in the~~ ~~TECO Energy Notes to Consolidated Condensed Financial Statements~~. TEC’s portion of the net pension expense for the three months ended Sept. 30, 2016 and 2015, respectively, was $3.5 million and $3.3 million for pension benefits, and $1.7 million and $1.4 million for other postretirement benefits. TEC’s portion of the net pension expense for the nine months ended Sept. 30, 2016 and 2015, respectively, was $9.6 million and $10.1 million for pension benefits, and $4.7 million and $4.3 million for other postretirement benefits.

For the Jan. 1, 2016 measurement, TECO Energy assumed a long-term EROA of 7.00% and a discount rate of 4.685% for pension benefits under its qualified pension plan. For the Jan. 1, 2016 measurement of TECO Energy’s other postretirement benefits, TECO Energy used a discount rate of 4.667%.

year. TECO Energy previously used a bond model matching technique to determine its discount rate. The change in discount rate resulting from the different methodology used to select a discount rate did not have a material impact on the company’s financial statements and provides consistency with Emera’s method for selecting a discount rate. For the July 1, 2016 measurement, TECO Energy used an assumed long-term EROA of 7.00% and a discount rate of 3.72% for pension benefits under its qualified pension plan. For the July 1, 2016 measurement of TECO Energy’s other postretirement benefits, TECO Energy assumed a discount rate of 3.85%.

As a result of the remeasurement, TEC’s net periodic benefit expense increased by $0.8 million for pension benefits and $0.3 million for other postretirement benefits for the three- and nine-months ended Sept. 30, 2016. TEC’s liability and associated regulatory asset for pension benefits increased $53.3 million and $12.4 million for other postretirement benefits.

TECO Energy made contributions of $37.4 million and $55.0 million to its qualified pension plan in the nine months ended Sept. 30, 2016 and 2015, respectively. TEC’s portion of the contributions was $30.9 million and $43.9 million, respectively.

Included in the benefit expenses discussed above, for the three and nine months ended Sept. 30, 2016, TEC reclassified $2.8 million and $7.6 million, respectively, of unamortized prior service benefit and actuarial losses from regulatory assets to net income, compared with $2.3 million and $7.0 million for the three and nine months ended Sept. 30, 2015, respectively.

~~Details of the credit facilities and related borrowings are presented in the following table:~~

At Sept. 30, 2016, these credit facilities required commitment fees ranging from 12.5 to 30.0 basis points. The weighted-average interest rate on outstanding amounts payable under the credit facilities at Sept. 30, 2016 and Dec. 31, 2015 was 1.32% and 0.89%, respectively.

At Sept. 30, 2016, TEC’s total long-term debt had a carrying amount of $2,162.6 million and an estimated fair market value of $2,505.6 million. At Dec. 31, 2015, TEC’s total long-term debt had a carrying amount of $2,245.0 million and an estimated fair market value of $2,433.3 million. TEC uses the market approach in determining fair value. The majority of the outstanding debt is valued using real-time financial market data obtained from Bloomberg Professional Service. The remaining securities are valued using prices obtained from the Municipal Securities Rulemaking Board or by applying estimated credit spreads obtained from a third party to the par value of the security. The fair value of debt securities totaling $58.3 million is determined using Level 1 measurements; the fair value of the remaining debt securities is determined using Level 2 measurements (see ~~Note 11~~ ~~for information regarding the fair value hierarchy).~~

On Mar. 19, 2008, the HCIDA remarketed $86.0 million HCIDA Pollution Control Revenue Refunding Bonds, Series 2006 (Non-AMT) (the Series 2006 HCIDA Bonds) in a term-rate mode pursuant to the terms of the Loan and Trust agreement governing those bonds. The Series 2006 HCIDA Bonds bore interest at a term rate of 5.00% per annum from Mar. 19, 2008 to Mar. 15, 2012. On Mar. 15, 2012, TEC purchased in lieu of redemption the Series 2006 HCIDA Bonds. The Series 2006 HCIDA Bonds bore interest at a term rate of 1.875% per annum from Mar. 15, 2012 to Mar. 15, 2016. On Mar. 15, 2016, pursuant to the terms of the Loan and Trust

Agreement governing the Series 2006 HCIDA Bonds, a mandatory tender occurred and a term rate of 2.00% per annum will apply from Mar. 15, 2016 to Mar. 15, 2020. The 2016 mandatory tender did not impact the Consolidated Condensed Balance Sheet. TEC is responsible for payment of the interest and principal associated with the Series 2006 HCIDA Bonds. Regularly scheduled principal and interest when due, are insured by Ambac Assurance Corporation.

As of Sept. 30, 2016, $232.6 million of bonds purchased in lieu of redemption, including the series 2006 HCIDA Bonds described above, were held by the trustee at the direction of TEC to provide an opportunity to evaluate refinancing alternatives.

From time to time, TEC and its subsidiaries are involved in various legal, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies in the ordinary course of its business. Where appropriate, accruals are made in accordance with accounting standards for contingencies to provide for matters that are probable of resulting in an estimable loss. The company believes the claims in the pending actions described below are without merit and intends to defend the matters vigorously.

In November 2010, heavy equipment operated at a road construction site being conducted by Posen Construction, Inc. struck a natural gas line causing a rupture and ignition of the gas and an outage in the natural gas service to Lee and Collier counties, Florida. PGS filed suit in April 2011 against Posen Construction, Inc. in Federal Court for the Middle District of Florida to recover damages for repair and restoration relating to the incident and Posen Construction, Inc. counter-claimed against PGS alleging negligence. In the first quarter of 2014, the parties entered into a settlement agreement that resolves the claims of the parties. In addition, a suit was filed in November 2011 by the Posen Construction, Inc. employee operating the heavy equipment involved in the incident in Lee County Circuit Court against PGS and a PGS contractor involved in the project, seeking damages for his injuries. The suit against PGS remains pending, with a trial currently expected in February 2017. The company is unable at this time to estimate the possible loss or range of loss with respect to this matter. While the outcome of such proceeding is uncertain, management does not believe that its ultimate resolution will have a material adverse effect on the company’s results of operations, financial condition or cash flows.

TEC, through its Tampa Electric and Peoples Gas divisions, is a PRP for certain superfund sites and, through its Peoples Gas division, for certain former manufactured gas plant sites. While the joint and several liability associated with these sites presents the potential for significant response costs, as of Sept. 30, 2016, TEC has estimated its ultimate financial liability to be $33.9 million, primarily at PGS. This amount has been accrued and is primarily reflected in the long-term liability section under “Deferred credits and other liabilities” on the Consolidated Condensed Balance Sheets. The environmental remediation costs associated with these sites, which are expected to be paid over many years, are not expected to have a significant impact on customer rates.

TEC must meet certain financial tests, including a debt to capital ratio, as defined in the applicable banking ~~agreements. TEC~~agreements and has certain restrictive covenants in specific agreements and debt instruments. At ~~Sept.~~September 30, ~~2016,~~2017, TEC was in compliance with all ~~applicable~~required financial covenants.

From time to time, TEC enters into futures, forwards, swaps and option contracts for the following purposes:

TEC uses derivatives only to reduce normal operating and market risks, not for speculative purposes. TEC’s primary objective in using derivative instruments for regulated operations is to reduce the impact of market price volatility on ~~ratepayers.~~customers.

The risk management policies adopted by TEC provide a framework through which management monitors various risk exposures. Daily and periodic reporting of positions and other relevant metrics are performed by a centralized risk management group, which is independent of all operating companies.

In November 2016, Tampa Electric and the other major electric IOUs in Florida signed a stipulation agreement approved by the FPSC calling for a one-year moratorium on hedging of natural gas purchases. In September 2017, Tampa Electric filed with the FPSC an amended and restated settlement agreement, which replaces the existing 2013 base rate settlement agreement and includes a provision for a five-year moratorium on hedging of natural gas purchases. The FPSC approved the agreement on November 6, 2017 (see Note 3).

TEC applies the accounting standards for derivative instruments and hedging activities. These standards require companies to recognize derivatives as either assets or liabilities in the financial statements, to measure those instruments at fair value and to reflect the changes in the fair value of those instruments as either components of OCI or in net income, depending on the designation of those

instruments (see Note 11). The changes in fair value that are recorded in OCI are not immediately recognized in current net income. As the underlying hedged transaction matures or the physical commodity is delivered, the deferred gain or loss on the related hedging instrument must be reclassified from OCI to earnings based on its value at the time of the instrument’s settlement. For effective hedge transactions, the amount reclassified from OCI to earnings is offset in net income by the market change of the amount paid or received

TEC applies the accounting standards for regulated operations to financial instruments used to hedge the purchase of natural gas for its regulated companies. These standards, in accordance with the FPSC, permit the changes in fair value of natural gas derivatives to be recorded as regulatory assets or liabilities reflecting the impact of hedging activities on the fuel recovery clause. As a result, these changes are not recorded in OCI (see Note 3).

TEC’s physical contracts qualify for the NPNS exception to derivative accounting rules, provided they meet certain criteria. Generally, NPNS applies if TEC deems the counterparty creditworthy, if the counterparty owns or controls resources within the proximity to allow for physical delivery of the commodity, if TEC intends to receive physical delivery and if the transaction is reasonable in relation to TEC’s business needs. As of ~~Sept.~~September 30, ~~2016,~~2017, all of TEC’s physical contracts qualify for the NPNS ~~exception.~~exception, which has been elected.

The derivatives that are designated as cash flow hedges at ~~Sept.~~September 30, ~~2016~~2017 and ~~Dec.~~December 31, ~~2015~~2016 are reflected on TEC’s Consolidated Condensed Balance Sheets and classified accordingly as current and ~~long-term~~long term assets and liabilities on a net basis as permitted by their respective master netting agreements. ~~Derivative~~There were approximately zero derivative assets ~~totaled $1.5 million~~ and ~~$0.0~~liabilities as of ~~Sept.~~September 30, ~~2016~~2017 and ~~Dec. 31, 2015, respectively. Derivative liabilities totaled $1.5~~$17 million ~~and $26.2 million~~of derivative assets as of ~~Sept. 30, 2016 and Dec.~~December 31, ~~2015, respectively.~~2016. There are minor offset amount differences between the gross derivative assets and liabilities and the net amounts included in the Consolidated ~~Condensed~~ Balance Sheets. There was no ~~cash~~ collateral posted with or received from any ~~counterparties.~~counterparties at September 30, 2017 and December 31, 2016.

All of the derivative ~~assets~~asset and liabilities at ~~Sept.~~September 30, ~~2016~~2017 and ~~Dec.~~December 31, ~~2015~~2016 are designated as hedging instruments, which primarily are derivative hedges of natural gas contracts to limit the exposure to changes in market price for natural gas used to produce energy and natural gas purchased for resale to customers. The corresponding effect of these natural gas related derivatives on the regulated utilities’ fuel recovery clause mechanism is reflected on the Consolidated ~~Condensed~~ Balance Sheets as current and long-term regulatory assets and liabilities. Based on the fair value of the instruments at ~~Sept.~~September 30, ~~2016,~~2017, there are no net ~~pretax losses of $0.1 million~~pre-tax reductions in fuel costs that are expected to be reclassified from regulatory assets or liabilities to the Consolidated ~~Condensed~~ Statements of Income within the next twelve months.

~~The Sept. 30, 2016 and Dec. 31, 2015 balance in AOCI related to the cash flow hedges and interest rate swaps (unsettled and previously settled) is presented in~~ ~~Note 12~~.

For derivative instruments that meet cash flow hedge criteria, the effective portion of the gain or loss on the derivative is reported as a component of OCI and reclassified into earnings in the same period or period during which the hedged transaction affects earnings. Gains and losses on the derivatives representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. For the three and nine months ended ~~Sept.~~September 30, ~~2016~~2017 and ~~2015,~~2016, all hedges were effective. The derivative after-tax effect on OCI and the amount of after-tax gain or loss reclassified from AOCI into earnings for the three and nine months ended ~~Sept.~~September 30, 2017 and 2016 ~~and 2015~~ is ~~presented in~~ ~~Note 12~~.$1 million or less for each period. Gains and losses were the result of interest rate contracts and the ~~reclassification~~reclassifications to income ~~was~~were reflected in ~~“Interest expense”.~~Interest expense.

The maximum length of time over which TEC is hedging its exposure to the variability in future cash flows extends to ~~Sept.~~November 30, 2018 for financial natural gas contracts. Due to low hedging volumes and low natural gas price volatility, TEC’s financial natural gas contracts resulted in zero derivative assets and liabilities as of September 30, 2017. The following table presents TEC’s derivative volumes that, as of ~~Sept.~~September 30, ~~2016,~~2017, are expected to settle during the ~~2016,~~ 2017 and 2018 fiscal years:

	Natural Gas Contracts				Natural Gas Contracts

TEC is exposed to credit risk by entering into derivative instruments with counterparties to limit its exposure to the commodity price fluctuations associated with natural gas. Credit risk is the potential loss resulting from a counterparty’s nonperformance under an agreement. TEC manages credit risk with policies and procedures for, among other things, counterparty analysis, exposure measurement and exposure monitoring and mitigation.

It is possible that volatility in commodity prices could cause TEC to have material credit risk exposures with one or more counterparties. If such counterparties fail to perform their obligations under one or more agreements, TEC could suffer a material financial loss. However, as of ~~Sept.~~September 30, ~~2016,~~2017, substantially all of the counterparties with transaction amounts outstanding in

TEC’s energy portfolio were rated investment grade by the major rating agencies. TEC assesses credit risk internally for counterparties that are not rated.

TEC has entered into commodity master arrangements with its counterparties to mitigate credit exposure to those counterparties. TEC generally enters into ~~the following~~standardized master ~~arrangements: (1) EEI agreements—standardized power sales contracts~~arrangements in the electric ~~industry; (2) ISDA agreements—standardized financial~~and gas ~~and electric contracts; and (3) NAESB agreements—standardized physical gas contracts.~~industry. TEC believes that entering into such agreements reduces the risk from default by creating contractual rights relating to creditworthiness, collateral and termination.

TEC has implemented procedures to monitor the creditworthiness of its counterparties and to consider nonperformance risk in determining the fair value of counterparty positions. Net liability positions generally do not require a nonperformance risk adjustment as TEC uses derivative transactions as hedges and has the ability and intent to perform under each of these contracts. In the instance of net asset positions, TEC considers general market conditions and the observable financial health and outlook of specific counterparties in evaluating the potential impact of nonperformance risk to derivative positions.

Certain TEC derivative instruments contain provisions that require TEC’s debt to maintain an investment grade credit rating from any or all of the major credit rating agencies. If debt ratings were to fall below investment grade, it could trigger these provisions, and the counterparties to the derivative instruments could demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions. TEC has no other contingent risk features associated with any derivative instruments.

Accounting guidance governing fair value measurements and disclosures provides that fair value represents the amount that would be received in selling an asset or the amount that would be paid in transferring a liability in an orderly transaction between market participants. As ~~such, fair value is~~ a ~~market-based measurement that is determined based upon~~basis for considering assumptions that market participants would use in pricing an asset or ~~liability. As a basis for considering such assumptions,~~liability, accounting guidance also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.

~~Assets and liabilities are measured at fair value based on one or more of the following three valuation techniques noted under accounting guidance:~~

~~(A)~~ ~~Market approach: Prices and other relevant information generated by market transactions involving~~

~~(B)~~ ~~Cost approach~~: ~~Amount that would be required to replace the service capacity of an asset (replacement~~

~~(C)~~ ~~Income approach~~: ~~Techniques to convert future amounts to a single present amount based upon market~~

~~expectations (including present value techniques, option-pricing and excess earnings models).~~

The fair value of financial instruments is determined by using various market data and other valuation techniques.

The following tables set forth by level within the fair value hierarchy, TEC’s financial assets and liabilities that were accounted for at fair value on a recurring basis. As required by accounting standards for fair value measurements, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. TEC’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

Natural gas swaps are OTC swap instruments. The fair value of the swaps is estimated utilizing the market approach. The price of swaps is calculated using observable NYMEX quoted closing prices of exchange-traded futures. These prices are applied to the notional quantities of active positions to determine the reported fair value (see Note 10).

TEC considered the impact of nonperformance risk in determining the fair value of derivatives. TEC considered the net position with each counterparty, past performance of both parties, the intent of the parties, indications of credit deterioration and whether the markets in which TEC transacts have experienced dislocation. ~~At Sept.~~As of September 30, ~~2016,~~2017, the fair value of derivatives was not materially affected by nonperformance risk. There were no Level 3 assets or liabilities for the periods presented.

As of September 30, 2017 and December 31, 2016, the carrying value of TEC’s short-term debt was not materially different from the fair value due to the short-term nature of the instruments and because the stated rates approximate market rates. The fair

value of TEC’s short-term debt is determined using Level 2 measurements. See Note 7 for information regarding the fair value of long-term debt.

A VIE is an entity that a company has a controlling financial interest in, and that controlling interest is determined through means other than a majority voting interest. The determination of a VIE’s primary beneficiary is the enterprise that has both 1) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and 2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE.

Tampa Electric has entered into multiple PPAs with wholesale energy providers in Florida to ensure the ability to meet customer energy demand and to provide lower cost options in the meeting of this demand. These agreements range in size from 117 MW to 250 MW of available capacity, are with similar entities and contain similar provisions. Because some of these provisions provide for the transfer or sharing of a number of risks inherent in the generation of energy, these agreements meet the definition of being variable interests. These risks include: operating and maintenance, regulatory, credit, commodity/fuel and energy market risk. Tampa Electric has reviewed these risks and has determined that the owners of these entities have retained the majority of these risks over the expected life of the underlying generating assets, have the power to direct the most significant activities, and have the obligation or right to absorb losses or benefits. As a result, Tampa Electric is not the primary beneficiary and is not required to consolidate any of these entities. Tampa Electric purchased ~~$19.1~~$5 million and ~~$48.1~~$13 million under these PPAs for the three and nine months ended ~~Sept.~~September 30, ~~2016,~~2017, respectively, and ~~$10.7~~$19 million and ~~$26.0~~$48 million for the three and nine months ended ~~Sept.~~September 30, ~~2015,~~2016, respectively.

TEC does not provide any material financial or other support to any of the VIEs it is involved with, nor is TEC under any obligation to absorb losses associated with these VIEs. In the normal course of business, TEC’s involvement with these VIEs does not affect its Consolidated Condensed Balance Sheets, Statements of Income or Cash Flows.

~~As disclosed in~~ ~~Note 1,~~ ~~TEC is a wholly owned subsidiary of TECO Energy.~~ 13. Subsequent Events

On ~~July 1, 2016, TECO Energy and Emera completed the Merger contemplated by the Merger Agreement~~November 2, 2017, TEC entered into ~~on Sept. 4, 2015. As~~ a result of the Merger, the Merger Sub Company merged with and into TECO Energy with TECO Energy continuing as the surviving corporation and becoming a wholly owned indirect subsidiary of Emera. Therefore, TEC continues to be a wholly owned subsidiary of TECO Energy and became an indirect wholly owned subsidiary of Emera as of July 1, 2016.

The Merger Agreement requires Emera, among other things, (i) to maintain TECO Energy’s historic levels of community involvement and charitable contributions and support in TECO Energy’s existing service territories, (ii) to maintain TECO Energy’s and TEC’s headquarters in Tampa, Florida, (iii) to honor current union contracts in accordance with their terms and (iv) to provide each continuing non-union employee, for a period of two years following the closing of the Merger,364-day, $300 million credit agreement with a ~~base salary~~consortium of banks. The credit agreement has a maturity date of November 1, 2018; contains customary representations and warranties, events of default, and financial and other covenants; and provides for interest to accrue at variable rates based on either the London interbank deposit rate, Wells Fargo Bank’s prime rate, or ~~wage~~the federal funds rate, ~~no less favorable than, and incentive compensation and employee benefits, respectively, substantially comparable in the aggregate to those that they received as of immediately prior to the closing.~~plus a margin.

This Management’s Discussion & Analysis contains forward-looking statements, which are subject to the inherent uncertainties in predicting future results and conditions. Actual results may differ materially from those forecasted. The forecasted results are based on ~~the company's~~ TEC's current expectations and assumptions, and ~~the company~~TEC does not undertake to update that information or any other information contained in this ~~Managements~~Management’s Discussion & Analysis, except as may be required by law. Factors that could impact actual results include: ~~the ability to retain and motivate the workforce during the period of integration with Emera;~~ regulatory actions or legislation by federal, state or local authorities; unexpected capital needs or unanticipated reductions in cash flow that affect liquidity; the ability to access the capital and credit markets when required; general economic conditions affecting customer growth and energy ~~sales at the utility companies;~~sales; economic conditions affecting the Florida ~~and New Mexico economies;~~ economy; weather variations and customer energy usage patterns affecting sales and operating costs ~~at the utilities~~ and the effect of weather conditions on energy consumption; the effect of extreme weather conditions or hurricanes; general operating conditions; input commodity prices affecting ~~cost at all of the operating companies;~~cost; natural gas ~~demand at the utilities~~;demand; and the ability of ~~TECO Energy's subsidiaries~~TEC to operate equipment without undue accidents, breakdowns or failures. Additional information is contained under "Risk Factors" in ~~TECO Energy’s~~TEC’s Annual Report on Form 10-K for the year ended ~~Dec.~~December 31, ~~2015 and the update in TECO Energy’s Quarterly Report on Form 10-Q for the quarterly period ended June 30,~~ 2016.

On July 1, 2016, TECO Energy’s Merger with Emera closed. Upon closing, TECO Energy became a wholly owned indirect subsidiary of Emera. Pursuant to the Merger Agreement, upon closing, each issued and outstanding share of TECO Energy common stock was cancelled and converted into the right to receive $27.55 in cash, without interest (see ~~Note 14~~ ~~to the~~ ~~TECO Energy Consolidated Financial Statements). The acquisition method of accounting was not pushed down to TECO Energy or its subsidiaries.~~

All amounts included in the operating company discussions below are after tax, unless otherwise noted.

Tampa Electric’s net income for the third quarter of ~~2016~~2017 was ~~$94.1~~$98 million, compared with ~~$82.1~~$94 million for the same period in 2015. Third-quarter net income in 2016 included $6.2 million of AFUDC-equity, which represents allowed equity cost capitalized to construction costs, and $6.2 million of federal R&D tax credits, compared with $4.6 million of AFUDC-equity in the 2015 quarter.2016. Results for the quarter reflected higher base revenue from higher base rates as a ~~1.6% higher average number~~result of ~~customers. Energy sales were higher due to above normal summer weather compared to~~ the ~~third quarter of 2015 when weather was only slightly above normal. Third quarter results also~~Polk Power Station expansion in January 2017. Results reflected ~~higher~~lower operations and maintenance expense, excluding all FPSC-approved cost-recovery clauses, and higher depreciation and property tax expenses. Third-quarter net income in 2017 included approximately zero of AFUDC-equity

compared with $6 million in the same period in 2016 due to the completion of the Polk Power Station expansion in January 2017. Results reflect a 1.7% increase in number of customers at September 30, 2017 compared to September 30, 2016.

In September 2017, Tampa Electric was impacted by Hurricane Irma. Incremental restoration expenditures are estimated at approximately $70 million pre-tax, with $60 million pre-tax charged to the storm reserve, $4 million pre-tax charged to O&M expense ~~than~~and $6 million pre-tax charged to capital expenditures. As discussed in ~~2015, as further discussed below.~~Note 3 to the TEC Consolidated Condensed Financial Statements, the storm reserve balance prior to Hurricane Irma was $46 million and therefore the difference of $14 million has been deferred in a regulatory asset for future recovery.

Total degree days (a measure of heating and cooling demand) in Tampa Electric's service area in the third quarter of ~~2016~~2017 were 8%7% above normal and ~~6% above~~equal to the ~~2015 period. Pretax~~2016 period, however total net energy for load decreased 0.9% in the third quarter of 2017, compared with the same period in 2016. This decrease was a result of lost sales due to outages associated with Hurricane Irma. Year-to-date, pre-tax base revenues were ~~$16.5~~$34 million higher than in ~~2015 due to higher energy sales from above normal weather, customer growth and a $1.5 million increase from~~2016, primarily driven by higher base rates ~~effective Nov. 1, 2015~~ as a result of the ~~2013 rate case settlement.~~

While net energy for load is a calendar measurement of retail energy sales rather than a billing-cycle measurement, the quarterly energy sales shown on the following table reflect the energy sales based on billing cycles, which can vary period to period. Retail energy sales to residential and commercial customers increased in the third quarter of 2016 primarily due to above-normal summer temperatures compared to the 2015 quarter when summer temperatures were slightly above normal. Sales to non-phosphate industrial customers increased due to the strengthexpansion of the ~~Tampa area economy. Sales to lower-margin industrial-phosphate customers increased as self-generation by those customers decreased.~~Polk Power Station in January 2017.

~~In the third quarter of 2016, operations~~Operations and maintenance expense, excluding all FPSC-approved cost-recovery clauses, ~~increased $4.0~~was $4 million ~~driven by~~lower than in the 2016 quarter, ~~higher employee-related accruals~~reflecting lower costs to operate and maintain the generation assets in ~~2016~~2017 compared to ~~2015.~~2016. Depreciation and amortization expense increased ~~$1.8~~$5 million in ~~2016~~the third quarter of 2017, as ~~a result of~~the Polk Power Station expansion was placed in service in January 2017 and from normal additions to facilities to reliably serve customers.

Tampa Electric’s ~~year-to-date~~ net income year-to-date 2017 was ~~$212.9~~$217 million, compared with ~~$198.0~~$213 million for the same period in ~~the 2015 period, driven by~~2016. Results reflected higher base ~~revenue~~revenues from ~~1.6%~~ higher ~~average number~~base rates described above, higher depreciation expense, higher property tax expense, and the impacts of ~~customers partially offset by higher operations and maintenance and depreciation expense.~~Hurricane Irma described above. Year-to-date net income in ~~2016~~2017 included ~~$17.8~~$1 million of AFUDC-equity, ~~and $6.2~~which decreased compared to $18 million ~~of federal R&D tax credits, compared with $12.1 million of AFUDC-equity~~ in the ~~2015 period. Energy sales were higher compared to 2015~~same period in 2016 due to the ~~above-normal third quarter temperatures and customer growth.~~completion of the Polk Power Station expansion in January 2017. Results reflect a 1.7% increase in the number of customers at September 30, 2017 compared to September 30, 2016.

~~Year-to-date total~~Total degree days in Tampa Electric's service area in the year-to-date period of 2017 were 6% above normal ~~but~~and 2% ~~below~~above the ~~2015~~2016 period ~~when~~as a result of warmer than normal spring weather offset by mild winter weather in the first quarter. Although year-to-date degree days ~~where 7% above normal. Total net~~were higher this year compared to the same period last year, the mix of heating and cooling degree days had an adverse effect on the residential sector's energy ~~for~~sales. The lack of heating degree days and heating appliance use as well as lost sales due to outages associated with Hurricane Irma resulted in residential sales lower than last year. In the non-residential sectors, which are not as sensitive to heating degree days, revenues were higher than in 2016. While total load ~~increased 1.8%~~was in-line with the amount in ~~the year-to-date 2016 period, compared with~~ the same period in ~~2015. In the~~ 2016, ~~year-to-date period, pretax base revenues were $20.2 million~~ higher ~~than in 2015, including approximately $4 million of higher pretax base revenue resulting from higher~~2017 base rates ~~effective Nov. 1, 2015 as~~were a result of the 2013 rate case ~~settlement.~~ settlement related to the expansion of the Polk Power Station in January 2017.

In the 2016 year-to-date period, retail energy sales to residential and commercial customers increased primarily from customer growth. Sales to non-phosphate industrial customers and to lower-margin industrial-phosphate customers increased as a result of the same factors as the third quarter.

~~In the 2016~~2017 year-to-date period, operations and maintenance expense, excluding all FPSC-approved cost-recovery clauses, was ~~approximately $5.0 million higher than~~slightly above the amount in ~~the 2015 period,~~ 2016reflecting higher costs to safely and reliably operate and maintain the generating, transmission and distribution systems and provide high-quality customer service; and higher employee-related costs, including higher short-term incentive accruals in 2016 compared to 2015.. Depreciation and amortization expense increased ~~$5.3~~$14 million in ~~2016,~~2017, as ~~a result of~~the Polk unit was placed in service in January 2017 and from normal additions to facilities to reliably serve customers.

As discussed in TEC’s Quarterly Report on Form 10-Q for the period ended June 30, 2017, on June 29, 2017, a tragic accident occurred during work being conducted at Tampa Electric's Big Bend Power Station Unit Two, resulting in employee and contractor fatalities. Although the financial impact to Tampa Electric has not been fully determined, any such impact is expected to be substantially covered by insurance.

~~NMGC reported a third-quarter~~ 2016 loss of $19.8 million, compared with a $2.8 million loss in the 2015 period. In the third quarter of 2016, NMGC recorded approximately $18 million of costs ($30.4 million pretax) related to the conditions contained in the Emera acquisition stipulation agreement approved by the NMPRC, of which the bill credit was recognized as a reduction in revenues and the remaining items recorded as expenses (see ~~Note 14~~ ~~to the~~ ~~TECO Energy Consolidated Financial Statements). Excluding the impact of the stipulation agreement, NMGC’s loss for the quarter was $1.3 million compared to the prior year quarter loss of $2.8 million.~~

Growth in the average number of customers in the 2016 third quarter and year-to-date periods were 0.6%. In the third quarter, heating degree days were above the 2015 quarter but 16% below normal. Excluding the costs related to the stipulation mentioned above, non-fuel operating and maintenance expense was slightly lower than in the 2015 quarter due to cost efficiency initiatives.

NMGC reported a year-to-date loss of $4.8 million compared with net income of $11.0 million in the 2015 period, due to the recording of costs in the third quarter related to the conditions contained in the Emera acquisition stipulation agreement. Excluding the impact of the stipulation agreement, year-to-date net income was $13.7 million compared to $11.0 million in 2015. Year-to-date results reflected customer growth and the benefit of heating degree days that were slightly higher than in 2015, but more than 4% below normal. Excluding the costs related to the stipulation mentioned above, operating and maintenance expense was slightly lower due to cost efficiency initiatives.

(1) The ~~segment data in~~ ~~Note 9~~number of 2016 customers reflects an updated customer count methodology due to the ~~TECO Energy Consolidated Condensed Financial Statements~~ ~~presents Other~~implementation of a new Customer Relationship Management and ~~Eliminations as separate segments. The discussion below nets the two segments.~~

The third quarter 2016 net loss for Other – net was $11.4 million, compared with $20.2 million in the third quarter 2015, which included $0.4 million income from discontinued operations. The third quarter 2016 net loss from continuing operations for Other – net was $11.4 million, which included $9.6 million of costs associated with the Emera transaction primarily for accelerated vesting of outstanding stock-based compensation awards, a $3.5 million tax benefit related to stock-based compensation awards paid in the third quarter, and a $3.2 million tax benefit related to recharacterizing certain prior year lobbying expenses as deductible for tax purposes. The third quarter 2015 net loss from continuing operations for Other-net was $20.6 million, which included $12.2 million of transaction costs related to the Emera transaction.

Year-to-date 2016 net loss for Other – net was $86.3 million, which included a $0.1 million loss from discontinued operations, compared with a net loss of $44.8 million for Other - net in the 2015 period, which included $2.4 million of income from discontinued operations related to TECO Coal. Year-to-date 2016 net loss from continuing operations for Other – net was $86.2 million, which included $68.1 of costs related to the Emera transaction primarily for employee-related and consultant fees, a $5.8 million tax benefit due to an accounting rule change related to stock-based incentive compensation recordedBilling System in the first quarter of ~~2016, lower interest expense as a result of refinancing debt maturities, and tax benefits recorded in~~2017.

For the third ~~quarter. In comparison, the~~quarter 2017 and 2016, other income was $2 million and $8 million, respectively, and included AFUDC-equity of zero and $6 million, respectively. For year-to-date ~~2015 net loss from continuing operations~~2017 and 2016, other income was ~~$47.2~~$7 million ~~which~~and $22 million, respectively, and included ~~$12.2~~AFUDC-equity of $1 million ~~of costs related~~and $18 million, respectively. The decrease in AFUDC-equity is due to ~~the Emera transaction and $1.2 million of NMGC integration-related costs.~~Tampa Electric’s Polk Power Station expansion being placed in service in January 2017.

The third quarter 2016 loss from discontinued operations was zero, compared with a $11.7 million loss in the 2015 period, which reflected TECO Coal’s operating results prior to its sale in September 2015 and a $7.7 million charge related to black lung liabilities. The year-to-date 2016 loss from discontinued operations was $0.1 million, compared with a loss of $67.2 million in the 2015 period, which reflected TECO Coal’s operating loss, net of impairment charges of $50.8 million and the black-lung related charge (see ~~Note 15~~ ~~to the~~ ~~TECO Energy Consolidated Financial Statements~~).

The provisions for income taxes ~~from continuing operations~~ for the ~~nine month~~2017 and 2016 year-to-date periods ~~ended Sept. 30, 2016 and 2015~~ were ~~$77.2~~$156 million and ~~$122.1~~$127 million, respectively. The provision for income taxes for the ~~nine months ended Sept. 30, 2016 was impacted by lower~~2017 year-to-date period increased due to higher pre-tax income and lower tax benefits related to ~~federal~~AFUDC-equity discussed above, the production deduction and R&D tax ~~credits and long-term incentive compensation, offset by the tax impact of the nondeductible Merger transaction costs (see~~ ~~Notes 2~~ ~~and~~ 14 ~~to the~~ ~~TECO Energy Consolidated Financial Statements~~).credits.

The table below sets forth the ~~Sept.~~September 30, ~~2016 consolidated~~2017 liquidity, ~~and~~ cash balances, ~~the cash balances at the operating companies and Parent,~~ and amounts available under the ~~TECO Energy/TECO Finance,~~ TEC ~~and NMGC~~ credit facilities.

Cash needs for the ~~March~~remainder of 2017 ~~maturity of the one-year term loan facility at TECO Finance~~ and ~~expect capital market conditions~~for 2018 will ~~continue to allow for a variety of financing options.~~

In 2016, TECO Energy had net cash outflows associated with the Merger of approximately $55 million. In 2017, TECO Energy expects to pay approximately $20 million, primarily representing transaction costs accrued at June 30, 2016. In connection with the stipulation agreement approvedbe impacted by the ~~NMPRC, pre-tax costs~~effects of ~~approximately $30 million were recorded~~Hurricane Irma and the increase in the third quarter of 2016, with associated cash outflows over a 5-year period. In addition, a $27 million pro-rated dividend was paid to TECO Energy shareholders in July 2016. During the third quarter of 2016, Emera contributed $22 million to TECO Energycapital expenditures primarily related to ~~funding accelerated stock compensation payments.~~ solar projects. The total cost of storm restoration to Tampa Electric’s system due to Hurricane Irma is currently estimated at $70 million. The amount of capital investments related to solar projects during 2017 – 2021 is currently estimated at approximately $850 million. See Note 3 to the TEC Consolidated Condensed Financial Statements and the Capital Investments section below for additional information regarding these items.

TEC expects to rely on cash on hand, internally generated cash from operations, borrowings under its existing credit facilities and the November 2017 credit facility, long-term debt issues, and equity contributions from TECO Energy to fund its needs in 2017 and 2018. TEC intends to fund these expenditures so that Tampa Electric and PGS maintain their capital structures consistent with the existing regulatory arrangements. See Note 13 to the TEC Consolidated Condensed Financial Statements for information on TEC’s credit facility entered into on November 2, 2017.

Cash flows from operating activities for the nine months ended ~~Sept.~~September 30, ~~2016 increased~~2017 were $462 million, a decrease of $240 million compared to the same period in ~~2015.~~2016. The ~~change~~decrease is primarily due to ~~a higher deferred recovery~~payments in 2017 related to significant December 2016 accruals for products and services; refunds to retail customers in 2017 for fuel clause ~~balance~~over-recoveries collected in 2016; lower fuel clause over-recoveries collected in 2017; and increased receivables due to over-recovery in 2016 as fuel prices were lower than projected, higher accounts payable primarily due to Merger-related transaction costs in 2016 and higher fuel and purchased power accruals, and lower fuel inventory due to increased use of coal units.delays resulting from Hurricane Irma.

In order to utilize ~~their respective~~its bank credit facilities, ~~TECO Energy and its subsidiaries~~TEC must meet certain financial tests as defined in the applicable agreements. In addition, ~~TECO Energy and its subsidiaries have~~TEC has certain restrictive covenants in specific agreements and debt instruments. At ~~Sept.~~September 30, ~~2016, TECO Energy and its subsidiaries were~~2017, TEC was in compliance with all ~~required~~applicable financial covenants. The table that follows lists the significant financial covenants and the performance relative to them at ~~Sept.~~September 30, ~~2016.~~2017. Reference is made to the specific agreements and instruments for more details.

On July 6, 2016, following the Merger with Emera, Moody’s downgraded the senior unsecured credit ratings of TECO Energy/TECO Finance to Baa2 from Baa1 and the issuer rating and senior unsecured ratings of Tampa Electric Company to A3 from A2. This concluded the ratings review commenced by Moody’s on June 2, 2016. Moody’s described the ratings outlook for the companies as “Stable”.

~~On July 1, 2016, following the Merger with Emera,~~ S&P ~~affirmed the issuer credit ratings of TECO Energy~~ and ~~the senior unsecured debt ratings of its subsidiaries, TECO Finance, Tampa Electric Company and NMGC, and maintained the ratings outlook at negative.~~

On Oct. 9, 2015, Fitch Ratings affirmed the issuer default ratings of TECO Energy at BBB and TEC at BBB+ and affirmed the senior unsecured debt rating of its subsidiaries, TECO Finance and TEC. Fitch Ratings also described the ratings outlook as "Stable".

~~S&P,~~ Moody’s ~~and Fitch~~ describe credit ratings in the BBB or Baa category as representing adequate capacity for payment of financial obligations. The lowest investment grade credit ratings for S&P is BBB-, and for Moody’s is ~~Baa3 and for Fitch is BBB-;~~Baa3; thus, ~~the~~both credit rating agencies assign ~~TECO Energy, TECO Finance, TEC and NMGC’s~~TEC’s senior unsecured debt investment-grade credit ratings.

A credit rating agency rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. Our access to capital markets and cost of financing, including the applicability of restrictive financial covenants, are influenced by the ratings of our securities. In addition, certain of TEC’s derivative instruments contain provisions that require TEC’s debt to maintain investment grade credit ratings (see Note 10 to the ~~TECO Energy~~TEC Consolidated Condensed Financial ~~Statements~~Statements)). The credit ratings listed above are included in this report in order to provide information that may be relevant to these matters and because downgrades, if any, in credit ratings may affect our ability to borrow and may increase financing costs, which may decrease earnings (see the ~~Risk Factors~~ ~~in Item 1A of~~ ~~Part II~~ ~~of this quarterly report). These credit~~

~~ratings are not necessarily applicable to any particular security that we may offer and therefore should not be relied upon for making a decision to buy, sell or hold any of our securities.~~

See Note 8 to the ~~TECO Energy~~TEC Consolidated Condensed Financial Statements for information regarding ~~the company’s~~TEC’s commitments and contingencies as of ~~Sept.~~September 30, ~~2016.~~2017.

On January 16, 2017, the expansion of Tampa Electric’s Polk Power Station went into service, resulting in a $524 million decrease in construction work in progress and increase in utility plant.

The 2017 forecasted capital expenditures shown below are based on current estimates and assumptions. The 2017 forecasted amounts have been updated from TEC’s Annual Report on Form 10-K to reflect expected increases in capital costs primarily related to land and equipment purchases for solar projects. Tampa Electric expects to spend approximately $850 million during 2017 through 2021 related to the 600 MW solar project recoverable under the SOBRAs as discussed in Note 3 to the TEC Consolidated Condensed Financial Statements. Actual capital expenditures could vary materially from these estimates due to changes in schedule, costs for materials or labor or changes in plans.

All natural gas derivatives were entered into by ~~the regulated utilities~~TEC to manage the impact of natural gas prices on customers. As a result of applying accounting standards for regulated operations, the changes in value of natural gas derivatives of Tampa Electric ~~PGS~~ and ~~NMGC~~PGS are recorded as regulatory assets or liabilities to reflect the impact of the risks of hedging activities in the fuel recovery clause. Because the amounts are deferred and ultimately collected through the fuel clause, the unrealized gains and losses associated with the valuation of these assets and liabilities do not impact our results of operations.

The valuation methods used to determine fair value are described in Notes 7 and 11 to the ~~TECO Energy~~TEC Consolidated Condensed Financial Statements. In addition, ~~the company~~TEC considered the impact of nonperformance risk in determining the fair value of derivatives. ~~The company~~TEC considered the net position with each counterparty, past performance of both parties and the intent of the parties, indications of credit deterioration and whether the markets in which ~~the company~~TEC transacts have experienced dislocation. At ~~Sept.~~September 30, ~~2016,~~2017, the fair value of derivatives was not materially affected by nonperformance risk.

~~The company’s critical~~Critical accounting policies ~~relate to deferred income taxes, employee postretirement benefits, long-lived assets, goodwill~~ and ~~regulatory accounting.~~estimates have not materially changed in 2017. For further discussion of critical accounting policies and estimates, see ~~TECO Energy’s~~TEC’s Annual Report on Form 10-K for the year ended ~~Dec.~~December 31, ~~2015.~~2016.

55On November 6, 2017, Emera announced that Nancy Tower, the current Chief Corporate Development Officer for Emera, will become the President and Chief Executive Officer of TEC upon Gordon Gillette’s retirement on November 30, 2017.

The change in fair value of derivatives is largely due to settlements of natural gas swaps and the ~~increase~~decrease in the average market price component of ~~the company’s~~TEC’s outstanding natural gas swaps of approximately 7%4% from ~~Dec.~~December 31, ~~2015~~2016 to ~~Sept.~~September 30, ~~2016. For~~2017. TEC decreased by 70% the natural gas ~~the company increased the~~ volume hedged as of ~~Sept.~~September 30, ~~2016~~2017 as compared to ~~Dec.~~December 31, ~~2015 by approximately 18%.~~2016.

The following tables summarize the changes in and the fair value balances of derivative assets (liabilities) for the nine-month period ended ~~Sept.~~September 30, ~~2016:~~2017:

As of September 30, 2017, there was a minor amount of unrealized derivative contract net assets. For all unrealized derivative contracts, the valuation is an estimate based on the best available information. Actual cash flows could be materially different from the estimated value upon maturity.

Where appropriate, accruals are made in accordance with accounting standards for contingencies to provide for matters that are probable of resulting in an estimable loss. ~~While~~TEC believes the ~~outcome~~final disposition of ~~such~~these proceedings ~~is uncertain, management does~~will not ~~believe that their ultimate resolution will~~ have a material ~~adverse~~ effect on ~~the company’s~~its results of operations, cash flows or financial ~~condition, or cash flows.~~position.

(1) These guarantees renew annually and are shown on the basis that they will continue to renew beyond 2020.
(2) The amounts shown represent the maximum theoretical amounts of cash collateral that TECO Energy would be required to post in the event of a downgrade below investment grade of its long-term debt ratings by the major credit rating agencies. Liabilities recognized represent the associated potential obligation related to net derivative liabilities under these agreements at Sept. 30, 2016. See Note 10 for additional information.
(3) These letters of indemnity guarantee payments to certain surety companies that issued reclamation bonds to the Commonwealths of Kentucky and Virginia in connection with TECO Coal's mining operations. Payments to the surety companies would be triggered if the reclamation bonds are called upon by either of these states and the permit holder, TECO Coal, does not pay the surety. The amounts shown represent the maximum theoretical amounts that TECO Energy would be required to pay to the surety companies. As discussed in Note 15, TECO Coal was sold on Sept. 21, 2015 to Cambrian. Pursuant to the SPA, Cambrian is obligated to file applications required in connection with the change of control with the appropriate governmental entities. Once the applicable governmental agency deems each application to be acceptable, Cambrian is obligated to post a bond or other appropriate collateral necessary to obtain the release of the corresponding bond secured by the TECO Energy indemnity for that permit. Until the bonds secured by TECO Energy's indemnity are released, TECO Energy's indemnity will remain effective. At the date of sale in September 2015, the letters of indemnity guaranteed $93.8 million. The company is working with Cambrian on the process to replace the bonds. Pursuant to the SPA, Cambrian has the obligation to indemnify and hold TECO Energy harmless from any losses incurred that arise out of the coal mining permits during the period commencing on the closing date through the date all permit approvals are obtained.
