The Executive also agrees that damages are an inadequate remedy for any breach of the restrictive provisions herein and that the Company shall, whether or not it is pursuing any potential remedies at law, be entitled to equitable relief in the form of preliminary and permanent injunctions without bond or other security upon any actual or threatened breach of the non-competition provisions herein. 12

Judgment upon the arbitrator s award may be entered in any court having jurisdiction thereof. 9. SECTION 409A COMPLIANCE 9.1 It is intended that compensation paid or delivered to the Executive pursuant to this Agreement is either paid in compliance with, or is exempt from, Section 409A of the Internal Revenue Code of 1986, as amended (the Code ) and the regulations promulgated thereunder ( Section 409A ). If the Executive notifies the Company (with specificity as to the reason therefor) that he believes that any provision of this Agreement (or of any award of compensation, including equity compensation or benefits) would cause him to incur any additional tax or interest under Section 409A and the Company concurs with such belief or the Company independently makes such determination, the Company shall, after consultation with the Executive, to the extent legally permitted and to the extent it is possible to timely reform the provision to avoid taxation under Section 409A, reform such provision to attempt to comply with Section 409A through good faith modifications to the minimum extent reasonably appropriate to conform with Section 409A. To the extent that any provision hereof is modified in order to comply with or be exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to both the Executive and the Company of the applicable provision without violating the 16

23 provisions of Section 409A but in any case Executive hereby agrees that all personal income taxes on his compensation under this Agreement and all penalties and interest with respect to such personal income taxes, if any, are his own responsibility. In no event shall the Company have any liability relating to the failure or alleged failure of any payment or benefit under this Agreement to comply with, or be exempt from, the requirements of Section 409A, or any similar Treasury regulations or IRS rules or regulations that replace or supersede Treasury Regulation Section 1.409A after the Effective Date and that relate to the same or similar subject matter as Treasury Regulation Section 1.409A. (i) Amounts Payable On Account of Termination: To the extent necessary to comply with Section 409A, for the purposes of determining when amounts subject to Section 409A that are payable upon Executive s termination of employment under this Agreement will be paid, termination of employment or words of similar import, as used in this Agreement, shall be construed as the date that Executive first incurs a separation from service within the meaning of Section 409A. (ii) Reimbursement: Any taxable reimbursement of business or other expenses as specified under this Agreement shall be subject to the following conditions: (A) the expenses eligible for reimbursement in one taxable year shall not affect the expenses eligible for reimbursement in any other taxable year; (B) the reimbursement of an eligible expense shall be made no later than the end of the year after the year in which such expense was incurred; (C) the right to reimbursement shall not be subject to liquidation or exchange for another benefit; and (D) in accordance with the policies, practices and procedures of the Company. (iii) Specified Employees: If the Executive is deemed on the date of termination to be a specified employee within the meaning of that term under Section 409A(a)(2)(B) of the Code, then with regard to any payment that is considered deferred compensation subject to Section 409A payable on account of a separation from service, such payment or benefit shall be made or provided at the date which is the earlier of (i) the expiration of the six (6)-month period measured from the date of such separation from service, and (ii) the date of the Executive s death (the Delay Period ). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this section (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum, with interest thereon calculated at the long-term applicable federal rate (annual compounding) under Section 1274(d) of the Code in effect on the date of termination of employment, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. (iv) Interpretative Rules: In applying Section 409A to amounts paid pursuant to this Agreement, any right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments. 17

25 Exhibit 99.1 Contact: Brett Perryman (617) OMAM Reports Financial and Operating Results for the Fourth Quarter and Year Ended December 31, 2017 Company Appoints Stephen H. Belgrad as President and Chief Executive Officer U.S. GAAP net loss of $(48.8) million ( $(0.45) per share) for the quarter, compared to net income of $25.3 million ( $0.21 per share) for the 2016 period, and net income of $4.2 million ( $0.04 per share) for the year compared to $126.4 million ( $1.05 per share) for full-year 2016 Economic net income of $48.7 million ( $0.44 per share) for the quarter, up 25.2% compared to the 2016 period, and $180.9 million ( $1.62 per share) for the year, up 24.7% compared to the 2016 period AUM of $243.0 billion at December 31, 2017 (reflecting the removal of $32.4 billion of Heitman assets in Q3'17) up 1.1% from December 31, 2016 Net client cash flows ("NCCF") for the quarter of $(3.7) billion with an annualized revenue impact of $6.8 million ; full year NCCF of $(6.0) billion with an annualized revenue impact of $32.9 million London - February 1, OM Asset Management plc (NYSE: OMAM) today reports its results for the quarter and full year ended December 31, OMAM had a strong finish to the year, posting year-over-year growth in ENI per share of 33% for the quarter and 34% for the year, while our U.S. GAAP earnings were impacted by tax reform in the U.S. said James J. Ritchie, OMAM s chairman and interim CEO. Our Affiliates continue to build on their long-term track records of outperformance, with assets representing 65%, 72% and 83% of revenue finishing the year ahead of benchmarks on a one-, three- and five-year basis, respectively. Although the fourth quarter was challenging from an AUM flow perspective, with net flows of $(3.7) billion, an average fee rate of 57 basis points on gross sales compared to 32 basis points on redemptions drove a positive annualized revenue impact of $6.8 million, continuing a trend which led to an annualized revenue impact of $32.9 million on net flows of $(6.0) billion for the year. While we remained committed to investment spending through collaborative organic growth initiatives, prudent expense management and scale have generated meaningful operating leverage, as our ENI operating margin increased 261 bps, to 38%, in We are also pleased with our progress executing on our growth strategy in We saw meaningful inflows in multiple Affiliate products that were seeded as part of OMAM s growth initiatives, including a large ACWI ex-us mandate sourced by our Global Distribution team. In addition, we benefited from our late-2016 acquisition of Landmark Partners, which diversified our business and meaningfully contributed to our earnings growth and margin expansion. We are committed to making additional, accretive investments in high quality boutique asset management firms, and are actively cultivating relationships with a wide range of entrepreneurial firms. "Finally, we are very pleased to announce the appointment of Steve Belgrad as our President and Chief Executive Officer, effective March 2, OMAM s Board of Directors considered a number of highly qualified candidates, and there was unanimous support for Steve. With Steve's appointment, following the completion of Old Mutual's sell-down in the fourth quarter, the Company has stability of ownership, governance, and management, and moves forward into 2018 focused on the continued execution of our growth strategy. In addition, I want to give my sincere thanks to John Rogers, who will be stepping down from the Board after successfully completing the CEO selection process as chair of the Nominating and Governance Committee. John will be replaced on the Board by Barbara Trebbi, a former portfolio manager and co-managing partner at Mercator Asset Management.

As previously noted, the difference between U.S. GAAP results and ENI increased between 2016 and 2017, primarily as a result of the treatment of the Landmark transaction. Please see Table 7 for additional details. (2) As previously disclosed, in August OMAM executed a non-binding term sheet to sell its stake in Heitman LLC to Heitman s management in a transaction that closed on January 5, Operational information (including AUM and flow data) excludes Heitman for the third and fourth quarters of 2017 (Heitman remains in operational information for the first half of 2017). Actual U.S. GAAP and ENI financial results continue to include Heitman through November 30, Please see "Definitions and Additional Notes." Please see Table 7 for a reconciliation of U.S. GAAP net income attributable to controlling interests to economic net income. 1

26 Assets Under Management and Flows In August 2017, the Company agreed in principal to sell its stake in Heitman LLC to Heitman s management. Pursuant to this term sheet, OMAM entered into a redemption agreement on November 17, Heitman continued to contribute to the Company s financial results through November 30, 2017 and the transaction closed on January 5, The Company has broken the Heitman assets under management ("AUM") and flows out of its AUM reporting as of July 1, 2017, in order to give the reader a better perspective of the ongoing business following the closing of this transaction. Unless specifically noted, flow information in this release includes flows from Heitman for the first half of 2017, but excludes it thereafter, and AUM data at September 30, 2017 and December 31, 2017 excludes the Heitman AUM. For a summary of the Company s AUM rollforward, please see Table 2 below. At December 31, 2017, OMAM s total AUM, reflecting the removal of $32.4 billion of Heitman AUM as of July 1, 2017, were $243.0 billion, up $7.1 billion, or 3.0%, compared to $235.9 billion at September 30, 2017, and up $2.6 billion, or 1.1%, compared to $240.4 billion at December 31, The increase in AUM during the three months ended December 31, 2017 reflects net market appreciation of $10.8 billion offset by net outflows of $(3.7) billion. For the three months ended December 31, 2017, OMAM s net flows were $(3.7) billion compared to $0.5 billion for the three months ended September 30, 2017 and $1.5 billion for the three months ended December 31, Hard asset disposals of $(0.1) billion, $(0.4) billion, and $(0.6) billion are reflected in the net flows for the three months ended December 31, 2017, September 30, 2017 and December 31, 2016, respectively. The net flows in the three months ended December 31, 2017 were impacted primarily by lumpy outflows in sub-advisory funds and the redemption of certain OM plc-related assets following the sale of Old Mutual's equity stake in the business. As of December 31, 2017, OM plc-related assets of $2.6 billion, with a weighted-average fee rate of 26 bps remain in the business. For the three months ended December 31, 2017, the annualized revenue impact of the net flows was $6.8 million, with gross inflows of $7.4 billion during the period into higher fee asset classes yielding approximately 57 bps, versus gross outflows and hard asset disposals in the same period of $(11.1) billion out of asset classes yielding approximately 32 bps. This compares to annualized revenue impact of net flows of $12.2 million for the three months ended September 30, 2017 and $14.6 million for the three months ended December 31, 2016 (see "Definitions and Additional Notes"). For the twelve months ended December 31, 2017, OMAM s net flows were $(6.0) billion compared to $(1.6) billion for the twelve months ended December 31, Net client cash flows before hard asset disposals were $(5.2) billion, compared to $2.3 billion in the prior year. For the twelve months ended December 31, 2017, the annualized revenue impact of the net flows was $32.9 million compared to $11.0 million for the twelve months ended December 31, Gross inflows of $31.0 billion in the twelve months ended December 31, 2017 yielded an average of approximately 51 bps compared to approximately 42 bps in the year-ago period while gross outflows and hard asset disposals of $(37.0) billion yielded approximately 34 bps in the twelve months ended December 31, 2017 compared to approximately 36 bps in the year-ago period. 2

As of December 31, 2017, the Company had $392.8 million of long-term bonds ($400.0 million face value, net of discount and fees), $0.0 million outstanding on its $350 million credit facility and $33.5 million drawn on a non-recourse seed capital financing facility (see below). Shareholders' equity (attributable to controlling interests) amounted to $75.4 million, which was negatively impacted in the fourth quarter by the Tax Cuts and Jobs Act (the "Tax Act"), which was signed into law on December 22, See below and "Financial Results - U.S. GAAP" for more details on the financial impact of the Tax Act. As a result of the enactment of the Tax Act, which reduced the federal corporate tax rate from 35% to 21% effective January 2018, the Company revalued its deferred tax assets and related liabilities as required under U.S. GAAP. Based on currently available information, the Company has reduced its deferred tax assets as of the enactment date of December 22, 2017, resulting in a one-time tax charge of approximately $121 million recorded in the three and twelve months ended December 31, The reduction in value of the Company s deferred tax assets is a non-cash charge required by U.S. GAAP and does not impact ENI. In addition, the Company recognized a one-time charge of $1.5 million in December 2017 related to the deemed repatriation of unremitted earnings of foreign subsidiaries. The reduction of the corporate tax rate and other provisions of the Tax Act resulted in a decrease to the Deferred Tax Asset Deed amounts owed by the Company to OM plc. As a result, a reduction of approximately $52 million was recorded to the Deferred Tax Asset Deed at December 31, 2017, however there remains a possibility for further reductions pending the continued evaluation of the Tax Act's impact on the value of the DTA Deed. The Company entered into the Deferred Tax Asset Deed with OM plc in October 2014 and amended the agreement in June Under the amended agreement, the Company agreed to make a payment of the net present value of its future tax benefits to OM plc valued as of December 31, This payment, originally valued at $142.6 million was to be made over three installments on each of June 30, 2017, December 31, 2017 and June 30, The initial payment of $45.5 million was paid on June 30, 2017; however as a result of the Tax Act, no additional payments have been made pending the continued evaluation of the impact of the Tax Act on the value of the Deferred Tax Asset Deed. The continuation of certain protections provided by OM plc related to the realized tax benefit resulting from the Company's use of deferred tax 3

28 assets remains unaffected. Additional information on the amended Deferred Tax Asset Deed can be found in the Company s Current Report on Form 8-K, filed on June 14, The impact of the Tax Act on the Company may differ materially from the estimates included herein and may be subject to further adjustments due to clarifications or guidance regarding the Tax Act and actions the Company may take in the future. As such, the Company will continue to evaluate the Tax Act to determine its impact on the Company and whether any further adjustments are warranted. As of December 31, 2017, the Company s ratio of third party borrowings to trailing twelve months Adjusted EBITDA was 1.4 x, below the Company s debt to trailing twelve months Adjusted EBITDA target range of x. Of the Company's cash and cash equivalents of $186.3 million at December 31, 2017, $114.6 million was held at Affiliates and $71.7 million was available at the Center. Following the closing of the sale of the Company's share of Heitman on January 5, 2018, the Company received $100 million in cash. Increases in other liabilities at December 31, 2017 reflect revaluation of the fair value of acquisition-related consideration and pre-acquisition employee equity related to Landmark. On July 17, 2017, the Company entered into a non-recourse seed capital facility collateralized entirely by its seed capital holdings and may borrow up to $65 million, so long as the borrowing does not represent more than 50% of the value of the eligible seed capital collateral. Since this facility is non-recourse to OMAM beyond the seed investments themselves, drawdowns under this facility are excluded from the Company s third party debt levels for purposes of calculating the Company s credit ratio covenants under its revolving credit facility. As of December 31, 2017, the Company has total seed holdings of $101.9 million.

29 Investment Performance Table 4 below presents a summary of the Company s investment performance as of December 31, 2017, September 30, 2017, and December 31, Performance is shown on a revenue-weighted basis, an equal-weighted basis and an asset-weighted basis. Please see Definitions and Additional Notes for further information on the calculation of performance.

The one-year results declined from the previous quarter due to several international strategies rolling off strong performance; however, the three-year period increased due to the strong returns of a domestic large cap value strategy, and the five-year period benefited from a managed volatility strategy rolling off negative returns. Financial Results: U.S. GAAP Table 5 below presents the Company s U.S. GAAP Statement of Operations. The Company's U.S. GAAP results for the three and twelve months ended December 31, 2017 have been negatively impacted by the Tax Act, as the Company had to write down the value of its deferred tax assets, which resulted in additional income tax expense. This writedown is somewhat offset by a reduction in amounts owed to OM plc under the Deferred Tax Asset Deed which resulted in increased income from continuing operations before taxes. The Company's net income tax expense was $131.3 million for the three months, and $132.8 million for the twelve months, ended December 31, For the three months ended December 31, 2017 and 2016, diluted earnings (loss) per share were $(0.45) and $0.21, respectively and net income (loss) attributable to controlling interests was $(48.8) million and $25.3 million, respectively, a decrease of $(74.1) million. U.S. GAAP revenue increased $62.6 million, or 33.5%, from $186.6 million for the three months ended December 31, 2016, to $249.2 million for the three months ended December 31, 2017, primarily reflecting higher bps on higher levels of average assets under management driven by rising markets and sales of alternative products. Operating expenses increased $66.7 million, or 42.7%, from $156.2 million for the three months ended December 31, 2016, to $222.9 million for the three months ended December 31, 2017, primarily due to increases in variable compensation, the revaluation of Affiliate equity and profits interests and higher Affiliate key employee distributions. As it relates to the Landmark transaction, under U.S. GAAP the fair value of both the contingent consideration and the portion of equity not acquired by the Company is recorded as compensation expense over the applicable term because service requirements exist for holders of these units. These units are also revalued each quarter, with any change recorded in that period as an adjustment to compensation expense. For the twelve months ended December 31, 2017 and 2016, diluted earnings per share were $0.04 and $1.05, respectively, a decrease of (96.2)%, and net income attributable to controlling interests was $4.2 million and $126.4 million, respectively, a 5

30 decrease of $(122.2) million, or (96.7)%. U.S. GAAP revenue increased $223.9 million, or 33.7%, from $663.5 million for the twelve months ended December 31, 2016, to $887.4 million for the twelve months ended December 31, 2017, primarily as a result of increases in management fees as a result of market appreciation and shifts into higher fee rate products, the Landmark acquisition and higher performance fees. Operating expenses increase d $308.5 million, or 60.7%, from $507.9 million for the twelve months ended December 31, 2016, to $816.4 million for the twelve months ended December 31, 2017, primarily as a result of higher compensation (see Table 6). The increase in compensation and benefits is predominantly due to increases in variable compensation, the revaluation of Affiliate equity and profit interests, and amortization of acquisitionrelated consideration and pre-acquisition employee equity associated with the Landmark acquisition. The effective tax rate increased to 96.8% for the twelve months ended December 31, 2017 from 25.3% for the twelve months ended December 31, 2016 due to the write-down of the value of the Company's deferred tax asset following passage of the Tax Act.

(2) For the twelve months ended December 31, 2017, $243.4 million of variable compensation expense (of the $252.2 million above) is included within economic net income, which excludes the variable compensation associated with the CEO transition costs. (3) Reflects amortization of contingent consideration and equity owned by employees, both with a service requirement, associated with the Landmark acquisition; revaluation of the Landmark interests is included in Non-cash key employee-owned equity revaluations above. Please see Definitions and Additional Notes Financial Results: Non-GAAP Economic Net Income For the three months ended December 31, 2017 and 2016, diluted economic net income per share was $0.44 and $0.33, respectively, an increase of 33.3%. For the three months ended December 31, 2017 and 2016, economic net income was $48.7 million and $38.9 million, respectively, an increase of $9.8 million, or 25.2%. Table 7 reconciles U.S. GAAP to economic net income for the three and twelve months ended December 31, 2017 and As was expected, the difference between U.S. GAAP net income attributable to controlling interests and economic net income increased between 2016 and This change was primarily related to the accounting treatment of the service component of the contingent consideration and employee equity in the Landmark transaction, as well as the level of non-cash key employee-owned equity revaluations, as the Affiliates grew their income and the corresponding value of employee equity. For the three months ended December 31, 2017, compared to the three months ended December 31, 2016, ENI Revenue (see Table 8) increase d $62.5 million, or 32.9%, from $189.8 million to $252.3 million, including an increase in management fees from $181.4 million to $233.9 million driven by positive markets and a continued shift into higher fee products. Average assets under management excluding equity accounted Affiliates in those respective periods (see Table 12) increased $34.0 billion, or 16.8%, to $236.8 billion, while the bps yield on these assets rose from 35.6 bps to 39.2 bps due to positive mix shifts related to markets and flows including the impact of higher yielding alternative assets. Performance fee revenue was $14.4 million for the current quarter, compared to $4.5 million in the year-ago quarter. The current quarter performance fees were principally attributable to strong performance from global/non-u.s. equity products. Other income, including equity-accounted Affiliates, includes $2.7 million for Heitman in each of the three months ended December 31, 2017 and 2016, respectively, representing 3.3% and 4.2% of economic net income on an after-tax basis in each respective period. Total ENI operating expenses (see Table 9) increase d 15.7% to $84.8 million, from $73.3 million in the prior-year quarter primarily as a result of ongoing investments in the business, however total ENI operating expenses as a percentage of management fee revenue decreased (415) bps from 40.4% to 36.3% as a result of increased scale in the business. Of the $11.5 million increase in operating expense between the three months ended December 31, 2017 and 2016, $5.1 million was due to higher fixed compensation and benefits as a result of new hires, CEO succession and annual cost of living increases and $5.6 million was attributable to increases in general and administrative expense, which rose 18.6% over the 2016 period, reflecting continued investment in the business. Total variable compensation increase d 43.2% quarter-over-quarter to $69.6 million, reflecting higher earnings before variable compensation, while the ENI variable compensation ratio (variable compensation as a percentage of ENI earnings before variable compensation) was stable at 41.6%. The sum of operating expense and variable compensation increased $32.5 million, or 26.7% period-over-period, while revenue increase d 32.9% over this period, resulting in an increase in OMAM s ENI operating margin to 38.8% from 35.8%. Included in operating expense and variable compensation in 2017 was $4.6 million related to severance for our former Head of Global Distribution. Affiliate key employee distributions increased 69.0% from the year-ago quarter from $12.9 million to $21.8 million, primarily due to higher ENI operating earnings and the levered structure of distributions at certain Affiliates. The ratio of Affiliate key employee distributions over ENI operating earnings increased from 19.0% to 22.3% due to higher earnings before Affiliate key employee distributions at Affiliates with higher employee ownership and leveraged equity plans which align incentives for growth. Net 7

32 interest expense was $4.4 million for the three months ended December 31, 2017, compared to net interest expense of $4.5 million in the prior-year period. The difference in net interest expense between U.S. GAAP and economic net income primarily relates to the financing costs of seed capital and co-investments held for the Company's benefit (see Table 21). Tax on economic net income for the three months ended December 31, 2017 and 2016 was $23.0 million and $11.6 million, respectively, an increase of $11.4 million or 98.3%, primarily reflecting higher pre-tax economic net income along with incremental U.K. taxes due to new U.K. tax legislation enacted in the fourth quarter. The Company's effective tax rate was 32.1% in the fourth quarter of 2017 compared to 23.0% in the fourth quarter of 2016 (see Table 23). For the three months ended December 31, 2017, Adjusted EBITDA was $79.4 million, an increase of 38.1% compared to $57.5 million for the same period in See Table 22 for a reconciliation of U.S. GAAP net income attributable to controlling interests to EBITDA, Adjusted EBITDA and economic net income. For the twelve months ended December 31, 2017 and 2016, diluted economic net income per share, was $1.62 and $1.21, respectively, an increase of 33.9%. For the twelve months ended December 31, 2017 and 2016, economic net income was $180.9 million and $145.1 million, respectively, an increase of $35.8 million, or 24.7%. Results for 2016 reflect the inclusion of Landmark from August 18, while 2017 results reflect ownership of Landmark for the full year. For the twelve months ended December 31, 2017, compared to the twelve months ended December 31, 2016, ENI Revenue increase d $222.2 million or 32.7%, from $678.5 million to $900.7 million, driven by a $198.1 million, or 30.0%, increase in management fees from $659.9 million to $858.0 million. Approximately half of this growth was related to the acquisition of Landmark, which increased both average assets under management and our weighted-average fee rate, with the remainder of the increase attributable to positive markets and asset mix. Average AUM excluding equity-accounted Affiliates increased 17.8% from the twelve months ended December 31, 2016 to $224.8 billion, and the bps yield on these assets rose from 34.6 bps to 38.2 bps primarily due to a greater proportion of AUM coming from global/non-u.s. and alternative products (see Table 12). Landmark contributed approximately 3 bps of this increase, with the remainder occurring as a result of a positive mix shift toward higher fee global/non-u.s. and alternative products due to flow trends and market movements. Performance fee revenue was $26.5 million for the current period, compared to $2.6 million in the year-ago period, reflecting a performance fee earned on an alternative product in the second quarter and strong performance from global/non-u.s. equity in the fourth quarter of Other income, including equity-accounted Affiliates, includes $12.0 million and $12.6 million for Heitman in the twelve months ended December 31, 2017 and 2016, respectively, representing 4.0% and 5.2% of economic net income on an after-tax basis in each respective period. Total ENI operating expenses (see Table 9) grew 18.5% to $314.1 million, from $265.0 million for the twelve months ended December 31, Total operating expenses as a percentage of management fee revenue decreased to 36.6% from 40.2% for the twelve months ended December 31, 2016, as management fee growth of 30.0% outpaced the 18.5% increase in operating expenses, partially reflecting efficiencies of scale following the Landmark transaction. Of the $49.1 million increase in operating expense between the twelve months ended December 31, 2016 and 2015, $26.0 million was due to higher fixed compensation and benefits as a result of the Landmark acquisition, new hires, CEO succession and annual cost of living increases. While total variable compensation increased $70.7 million, or 40.9%, period-over-period to $243.4 million, the ENI variable compensation ratio (variable compensation as a percentage of ENI earnings before variable compensation) decreased slightly to 41.5% for the twelve months ended December 31, 2017 compared to 41.8% for the twelve months ended December 31, The sum of operating expense and variable compensation increased $119.8 million, or 27.4% period-over-period, while revenue increased 32.7% over this period, resulting in an increase in OMAM s ENI operating margin to 38.1% from 35.5%. Affiliate key employee distributions increased 75.3% period-over-period from $41.7 million to $73.1 million, primarily due to the investment in Landmark, the levered structure of distributions at certain Affiliates and higher ENI operating earnings. The ratio of Affiliate key employee distributions over ENI operating earnings increased from 17.3% to 21.3% due to the effect of the Landmark transaction and the leveraged structure of certain equity plans in a rising profit environment. Net interest expense was $18.8 million for the twelve months ended December 31, 2017, compared to net interest expense of $8.4 million in the prior-year period, with the increase reflecting the July 2016 issuance of $400 million of senior notes. The effective tax rate of 28.0% for the period was higher than the prior year period of 23.9% primarily due to higher pre-tax profits in the U.S. and the change in U.K. tax law enacted in the fourth quarter. For the twelve months ended December 31, 2017, Adjusted EBITDA was $281.9 million, up 35.2% compared to $208.5 million in See Table 22 for a reconciliation of U.S. GAAP net income attributable to controlling interests to EBITDA, Adjusted EBITDA and ENI. Finally, as a result of the enactment of the Tax Act, the Company expects its effective ENI tax rate to decrease from approximately 32% in 2018 to between 23% and 24% and its U.S. aggregate marginal tax rate to decrease from 39% to 26%. 8

44 Definitions and Additional Notes References to OMAM or the Company refer to OM Asset Management plc; references to OM plc refer to Old Mutual plc, the Company's former parent; references to the "Center" refer to the holding company excluding the Affiliates; references to "Landmark" refer to Landmark Partners, LLC, acquired by the Company in August OMAM operates its business through seven boutique asset management firms (the Affiliates ). OMAM's distribution activities are conducted in various jurisdictions through affiliated companies in accordance with local regulatory requirements. Economic Net Income The Company uses a non-gaap performance measure referred to as economic net income ( ENI ) to represent its view of the underlying economic earnings of the business. ENI is used to make resource allocation decisions, determine appropriate levels of investment or dividend payout, manage balance sheet leverage, determine Affiliate variable compensation and equity distributions, and incentivize management. The Company s ENI adjustments to U.S. GAAP include both reclassifications of U.S. GAAP revenue and expense items, as well as adjustments to U.S. GAAP results, primarily to exclude non-cash, non-economic expenses, or to reflect cash benefits not recognized under U.S. GAAP. The Company re-categorizes certain line items on the income statement to: exclude the effect of Fund consolidation by removing the portion of Fund revenues, expenses and investment return which is not attributable to its shareholders; include within management fee revenue any fees paid to Affiliates by Consolidated Funds, which are viewed as investment income under U.S. GAAP; include the Company s share of earnings from equity-accounted Affiliates within other income, rather than investment income; treat sales-based compensation as a general and administrative expense, rather than part of fixed compensation and benefits; identify separately from operating expenses, variable compensation and Affiliate key employee distributions, which represent Affiliate earnings shared with Affiliate key employees. The Company also makes the following adjustments to U.S. GAAP results to more closely reflect its economic results by: i. excluding non-cash expenses representing changes in the value of Affiliate equity and profit interests held by Affiliate key employees. These ownership interests may in certain circumstances be repurchased by OMAM at a value based on a pre-determined fixed multiple of trailing earnings and as such this value is carried on the Company s balance sheet as a liability. Non-cash movements in the value of this liability are treated as compensation expense under U.S. GAAP. However, any equity or profit interests repurchased by OMAM can be used to fund a portion of future variable compensation awards, resulting in savings in cash variable compensation that offset the negative cash effect of repurchasing the equity. ii. excluding non-cash amortization or impairment expenses related to acquired goodwill and other intangibles as these are non-cash charges that do not result in an outflow of tangible economic benefits from the business. It also excludes the amortization of acquisition-related contingent consideration, as well as the value of employee equity owned pre-acquisition, as occurred as a result of the Landmark transaction, where such items have been included in compensation expense as a result of ongoing service requirements for certain employees. Please note that the revaluations related to these acquisition-related items are included in (i) above. iii. excluding capital transaction costs, including the costs of raising debt or equity, gains or losses realized as a result of redeeming debt or equity and direct incremental costs associated with acquisitions of businesses or assets. iv. excluding seed capital and co-investment gains, losses and related financing costs. The net returns on these investments are considered and presented separately from ENI because ENI is primarily a measure of the Company's earnings from managing client assets, which therefore differs from earnings generated by its investments in Affiliate products, which can be variable from period to period. v. including cash tax benefits associated with deductions allowed for acquired intangibles and goodwill that may not be recognized or have timing differences compared to U.S. GAAP. vi. excluding the results of discontinued operations attributable to controlling interests since they are not part of the Company s ongoing business, and restructuring costs incurred in continuing operations which represent an exit from a distinct product or line of business. vii. excluding deferred tax resulting from changes in tax law and expiration of statutes, adjustments for uncertain tax positions, deferred tax attributable to intangible assets and other unusual items not related to current operating results to reflect ENI tax normalization. 19

45 The Company adjusts its income tax expense to reflect any tax impact of its ENI adjustments. Please see Table 7 for a reconciliation of net income attributable to controlling interests to economic net income. Adjusted EBITDA Adjusted EBITDA is defined as economic net income before interest, income taxes, depreciation and amortization. The Company notes that its calculation of Adjusted EBITDA may not be consistent with Adjusted EBITDA as calculated by other companies. The Company believes Adjusted EBITDA is a useful liquidity metric because it indicates the Company s ability to make further investments in its business, service debt and meet working capital requirements. Please see Table 22 for a reconciliation of economic net income to Adjusted EBITDA. Methodologies for calculating investment performance (1) : Revenue-weighted investment performance measures the percentage of management fee revenue generated by Affiliate strategies which are beating benchmarks. It calculates each strategy s percentage weight by taking its estimated composite revenue over total composite revenues in each period, then sums the total percentage of revenue for strategies outperforming. Equal-weighted investment performance measures the percentage of Affiliates scale strategies (defined as strategies with greater than $100 million of AUM) beating benchmarks. Each outperforming strategy over $100 million has the same weight; the calculation sums the number of strategies outperforming relative to the total number of composites over $100 million. Asset-weighted investment performance measures the percentage of AUM in strategies beating benchmarks. It calculates each strategy s percentage weight by taking its composite AUM over total composite AUM in each period, then sums the total percentage of AUM for strategies outperforming. (1) Barrow Hanley s Windsor II Large Cap Value account AUM and return are separated from Barrow Hanley s Large Cap Value composite in revenue-weighted, equal-weighted and asset-weighted outperformance percentage calculations. ENI Operating Earnings ENI operating earnings represents ENI earnings before Affiliate key employee distributions and is calculated as ENI revenue, less ENI operating expense, less ENI variable compensation. It differs from economic net income because it does not include the effects of Affiliate key employee distributions, net interest expense or income tax expense. ENI Operating Margin The ENI operating margin, which is calculated before Affiliate key employee distributions, is used by management and is useful to investors to evaluate the overall operating margin of the business without regard to our various ownership levels at each of the Affiliates. ENI operating margin is a non-gaap efficiency measure, calculated based on ENI operating earnings divided by ENI revenue. The ENI operating margin is most comparable to our U.S. GAAP operating margin. ENI management fee revenue ENI Management fee revenue corresponds to U.S. GAAP management fee revenue. ENI operating expense ratio The ENI operating expense ratio is used by management and is useful to investors to evaluate the level of operating expense as measured against our recurring management fee revenue. We have provided this ratio since many operating expenses, including fixed compensation & benefits and general and administrative expense, are generally linked to the overall size of the business. We track this ratio as a key measure of scale economies at OMAM because in our profit sharing economic model, scale benefits both the Affiliate employees and OMAM shareholders. ENI earnings before variable compensation ENI earnings before variable compensation is calculated as ENI revenue, less ENI operating expense. 20

46 ENI variable compensation ratio The ENI variable compensation ratio is calculated as variable compensation divided by ENI earnings before variable compensation. It is used by management and is useful to investors to evaluate consolidated variable compensation as measured against our ENI earnings before variable compensation. Variable compensation is usually awarded based on a contractual percentage of each Affiliate s ENI earnings before variable compensation and may be paid in the form of cash or non-cash Affiliate equity or profit interests. Center variable compensation includes cash and OMAM equity. Non-cash variable compensation awards typically vest over several years and are recognized as compensation expense over that service period. The variable compensation ratio at each Affiliate will typically be between 25% and 35%. ENI Affiliate key employee distribution ratio The Affiliate key employee distribution ratio is calculated as Affiliate key employee distributions divided by ENI operating earnings. The ENI Affiliate key employee distribution ratio is used by management and is useful to investors to evaluate Affiliate key employee distributions as measured against our ENI operating earnings. Affiliate key employee distributions represent the share of Affiliate profits after variable compensation that is attributable to Affiliate key employee equity and profit interests holders, according to their ownership interests. At certain Affiliates, OMUS is entitled to an initial preference over profits after variable compensation, structured such that before a preference threshold is reached, there would be no required key employee distributions, whereas for profits above the threshold the key employee distribution amount would be calculated based on the key employee ownership percentages, which range from approximately 20% to 40% at our consolidated Affiliates. U.S. GAAP operating margin U.S. GAAP operating margin equals operating income (loss) from continuing operations divided by total revenue. Consolidated Funds Financial information presented in accordance with U.S. GAAP may include the results of consolidated pooled investment vehicles, or Funds, managed by our Affiliates, where it has been determined that these entities are controlled by the Company. Financial results which are attributable to controlling interests exclude the impact of Funds to the extent it is not attributable to our shareholders. Annualized Revenue Impact of Net Flows (NCCF) Annualized revenue impact of net flows represents the difference between annualized management fees expected to be earned on new accounts and net assets contributed to existing accounts, less the annualized management fees lost on terminated accounts or net assets withdrawn from existing accounts, including equity-accounted Affiliates. Annualized revenue is calculated by multiplying the annual gross fee rate for the relevant account by the net assets gained in the account in the event of a positive flow or the net assets lost in the account in the event of an outflow and is designed to provide investors with a better indication of the potential financial impact of net client cash flows. Hard asset disposals Net flows in Table 1, Table 2 and Table 11 include hard asset disposals made by OMAM s Affiliates. This category is made up of investment-driven asset dispositions made by Landmark, investing in real estate funds and secondary private equity; Heitman, a real estate manager; or Campbell, a timber manager. Derived average weighted NCCF Derived average weighted NCCF reflects the implied NCCF if annualized revenue represents asset flows at the weighted fee rate for OMAM overall (i.e bps in Q4 '17). For example, NCCF annualized revenue impact of $6.8 million divided by the average weighted fee rate of OMAM's overall AUM of 39.3 bps equals the derived average weighted NCCF of $1.7 billion. n/m "Not meaningful."

70 Definitions and Additional Notes 24 References to OMAM or the Company refer to OM Asset Management plc; references to OM plc refer to Old Mutual plc, the Company s former parent; references to the Center refer to the holding company excluding the Affiliates; references to "Landmark" refer to Landmark Partners, LLC, acquired by the Company in August OMAM operates its business through seven boutique asset management firms (the Affiliates ). OMAM s distribution activities are conducted in various jurisdictions through affiliated companies in accordance with local regulatory requirements. The Company uses a non-gaap performance measure referred to as economic net income ( ENI ) to represent its view of the underlying economic earnings of the business. ENI is used to make resource allocation decisions, determine appropriate levels of investment or dividend payout, manage balance sheet leverage, determine Affiliate variable compensation and equity distributions, and incentivize management. The Company s ENI adjustments to U.S. GAAP include both reclassifications of U.S. GAAP revenue and expense items, as well as adjustments to U.S. GAAP results, primarily to exclude non-cash, non-economic expenses, or to reflect cash benefits not recognized under U.S. GAAP. The Company re-categorizes certain line items on the income statement to: exclude the effect of Funds consolidation by removing the portion of Fund revenues, expenses and investment return which were not attributable to our shareholders. include within management fee revenue any fees paid to Affiliates by consolidated Funds, which are viewed as investment income under U.S. GAAP. include the Company s share of earnings from equity-accounted Affiliates within other income, rather than investment income; treat sales-based compensation as a general and administrative expense, rather than part of fixed compensation and benefits; identify separately from operating expenses, variable compensation and Affiliate key employee distributions, which represent Affiliate earnings shared with Affiliate key employees. The Company also makes the following adjustments to U.S. GAAP results to more closely reflect its economic results by: i. excluding non-cash expenses representing changes in the value of Affiliate equity and profit interests held by Affiliate key employees. These ownership interests may in certain circumstances be repurchased by OMAM at a value based on a pre-determined fixed multiple of trailing earnings and as such this value is carried on the Company s balance sheet as a liability. Non-cash movements in the value of this liability are treated as compensation expense under U.S. GAAP. However, any equity or profit interests repurchased by OMAM can be used to fund a portion of future variable compensation awards, resulting in savings in cash variable compensation that offset the negative cash effect of repurchasing the equity. ii. excluding non-cash amortization or impairment expenses related to acquired goodwill and other intangibles as these are non-cash charges that do not result in an outflow of tangible economic benefits from the business. It also excludes the amortization of acquisition-related contingent consideration, as well as the value of employee equity owned pre-acquisition, as occurred as a result of the Landmark transaction, where such items have been included in compensation expense as a result of ongoing service requirements for certain employees. Please note that the revaluations related to these acquisition-related items are included in (i) above. iii. excluding capital transaction costs, including the costs of raising debt or equity, gains or losses realized as a result of redeeming debt or equity and direct incremental costs associated with acquisitions of businesses or assets. iv. excluding seed capital and co-investment gains, losses and related financing costs. The net returns on these investments are considered and presented separately from ENI because ENI is primarily a measure of the Company s earnings from managing client assets, which therefore differs from earnings generated by its investments in Affiliate products, which can be variable from period to period. v. including cash tax benefits associated with deductions allowed for acquired intangibles and goodwill that may not be recognized or have timing differences compared to U.S. GAAP. vi. excluding the results of discontinued operations attributable to controlling interests since they are not part of the Company s ongoing business, and restructuring costs incurred in continuing operations which represent an exit from a distinct product or line of business. vii. excluding deferred tax resulting from changes in tax law and expiration of statutes, adjustments for uncertain tax positions, deferred tax attributable to intangible assets and other unusual items not related to current operating results to reflect ENI tax normalization.

71 The Company adjusts its income tax expense to reflect any tax impact of its ENI adjustments. Please see Slide 19 for a reconciliation of U.S. GAAP net income attributable to controlling interests to economic net income. Adjusted EBITDA Adjusted EBITDA is defined as economic net income before interest, income taxes, depreciation and amortization. The Company notes that its calculation of Adjusted EBITDA may not be consistent with Adjusted EBITDA as calculated by other companies. The Company believes Adjusted EBITDA is a useful liquidity metric because it indicates the Company s ability to make further investments in its business, service debt and meet working capital requirements. Please see Slide 19 for a reconciliation of U.S. GAAP net income attributable to controlling interests to ENI and Adjusted EBITDA. Methodologies for calculating investment performance(1): Revenue-weighted investment performance measures the percentage of management fee revenue generated by Affiliate strategies which are beating benchmarks. It calculates each strategy s percentage weight by taking its estimated composite revenue over total composite revenues in each period, then sums the total percentage of revenue for strategies outperforming. Equal-weighted investment performance measures the percentage of Affiliates scale strategies (defined as strategies with greater than $100 million of AUM) beating benchmarks. Each outperforming strategy over $100 million has the same weight; the calculation sums the number of strategies outperforming relative to the total number of composites over $100 million. Asset-weighted investment performance measures the percentage of AUM in strategies beating benchmarks. It calculates each strategy s percentage weight by taking its composite AUM over total composite AUM in each period, then sums the total percentage of AUM for strategies outperforming. ENI operating earnings ENI operating earnings represents ENI earnings before Affiliate key employee distributions and is calculated as ENI revenue, less ENI operating expense, less ENI variable compensation. It differs from economic net income because it does not include the effects of Affiliate key employee distributions, net interest expense or income tax expense. ENI operating margin The ENI operating margin, which is calculated before Affiliate key employee distributions, is used by management and is useful to investors to evaluate the overall operating margin of the business without regard to our various ownership levels at each of the Affiliates. ENI operating margin is a non-gaap efficiency measure, calculated based on ENI operating earnings divided by ENI revenue. The ENI operating margin is most comparable to our U.S. GAAP operating margin. ENI management fee revenue ENI Management fee revenue corresponds to U.S. GAAP management fee revenue. ENI operating expense ratio The ENI operating expense ratio is used by management and is useful to investors to evaluate the level of operating expense as measured against our recurring management fee revenue. We have provided this ratio since many operating expenses, including fixed compensation & benefits and general and administrative expense, are generally linked to the overall size of the business. We track this ratio as a key measure of scale economies at OMAM because in our profit sharing economic model, scale benefits both the Affiliate employees and OMAM shareholders. Definitions and Additional Notes 25 (1) Barrow Hanley s Windsor II Large Cap Value account AUM and return are separated from Barrow Hanley s Large Cap Value composite in revenue-weighted, equal-weighted and asset- weighted outperformance percentage calculations.

72 ENI earnings before variable compensation ENI earnings before variable compensation is calculated as ENI revenue, less ENI operating expense. ENI variable compensation ratio The ENI variable compensation ratio is calculated as variable compensation divided by ENI earnings before variable compensation. It is used by management and is useful to investors to evaluate consolidated variable compensation as measured against our ENI earnings before variable compensation. Variable compensation is usually awarded based on a contractual percentage of each Affiliate s ENI earnings before variable compensation and may be paid in the form of cash or non-cash Affiliate equity or profit interests. Center variable compensation includes cash and OMAM equity. Non-cash variable compensation awards typically vest over several years and are recognized as compensation expense over that service period. The variable compensation ratio at each Affiliate will typically be between 25% and 35%. ENI Affiliate key employee distribution ratio The Affiliate key employee distribution ratio is calculated as Affiliate key employee distributions divided by ENI operating earnings. The ENI Affiliate key employee distribution ratio is used by management and is useful to investors to evaluate Affiliate key employee distributions as measured against our ENI operating earnings. Affiliate key employee distributions represent the share of Affiliate profits after variable compensation that is attributable to Affiliate key employee equity and profit interests holders, according to their ownership interests. At certain Affiliates, OMUS is entitled to an initial preference over profits after variable compensation, structured such that before a preference threshold is reached, there would be no required key employee distributions, whereas for profits above the threshold the key employee distribution amount would be calculated based on the key employee economic percentages, which range from approximately 20% to 40% at our consolidated Affiliates. U.S. GAAP operating margin U.S. GAAP operating margin equals operating income from continuing operations divided by total revenue. Consolidated Funds Financial information presented in accordance with U.S. GAAP may include the results of consolidated pooled investment vehicles, or Funds, managed by our Affiliates, where it has been determined that these entities are controlled by the Company. Financial results which are attributable to controlling interests exclude the impact of Funds to the extent it is not attributable to our shareholders. Annualized revenue impact of net flows ( NCCF ) Annualized revenue impact of net flows represents the difference between annualized management fees expected to be earned on new accounts and net assets contributed to existing accounts, less the annualized management fees lost on terminated accounts or net assets withdrawn from existing accounts, including equity-accounted Affiliates. Annualized revenue is calculated by multiplying the annual gross fee rate for the relevant account by the net assets gained in the account in the event of a positive flow or the net assets lost in the account in the event of an outflow and is designed to provide investors with a better indication of the potential financial impact of net client cash flows. Hard asset disposals Net flows include hard asset disposals and fund distributions made by OMAM s Affiliates. This category is made up of investment-driven asset dispositions by Landmark, investing in real estate funds and secondary private equity; Heitman, a real estate manager; or Campbell, a timber manager. Derived average weighted NCCFDerived average weighted NCCF reflects the implied NCCF if annualized revenue represents asset flows at the weighted fee rate for OMAM overall (i.e bps in Q4 17). For example, NCCF annualized revenue impact of $6.8 million divided by the average weighted fee rate of OMAM s overall AUM of 39.3 bps equals the derived average weighted NCCF of $1.7 billion. n/m Not meaningful.
