London - August 6, 2015 - OM Asset Management plc (NYSE: OMAM) today reports its results for the second quarter ended June 30, 2015. 

“OMAM continues to execute across all elements of our growth strategy,” said Peter L. Bain, OMAM’s President and Chief Executive Officer. “Our core business generated strong results during the second quarter, driven by solid organic growth across our Affiliates. Our net client cash flows of $786 million for the quarter contributed $13.5 million to annualized revenue and, for the first six months, annualized revenue of $24.8 million from NCCF represented over 3% of beginning of year run rate management fees. In addition, during a period of flat returns in the equity markets, our Affiliates produced excellent relative investment performance; as of June 30, AUM representing 70%, 74% and 89% of revenue outperformed benchmarks on a 1-, 3- and 5-year basis. While we were pleased to realize a net extraordinary performance fee of $11.4 million, we are particularly encouraged that our ENI per share excluding that fee grew 14.3% year-over-year, to $0.32.”

Mr. Bain continued, “With the completion of our secondary equity offering in June, which resulted in Old Mutual plc’s sale of 15,295,000 shares, we augmented the liquidity of our stock and expanded our public shareholder base. We also deepened the capabilities of our Global Distribution team this quarter with the addition of Trevedi Tewari in London, who will focus on relationships with institutional investors and consultants in the U.K. and Ireland, and Steve Coyle in Boston, who will further develop our subadvisory new business initiatives. Assets raised by our Global Distribution initiative were approximately $1 billion in the first six months of 2015.

“In addition, our business remains well positioned to support our collaborative growth initiatives, as well as finance accretive investments in new Affiliates. We continue to make good progress in identifying and developing relationships with at-scale asset management boutiques who possess strong investment and executive talent and a vision to enhance and expand their businesses.”

Assets Under Management and Flows

At June 30, 2015, OMAM’s total assets under management (“AUM”) were $226.6 billion, up $2.6 billion or 1.2% compared to $224.0 billion at March 31, 2015, and up $11.7 billion or 5.4% compared to $214.9 billion at June 30, 2014. The increase in AUM during the three months ended June 30, 2015 reflects net market appreciation of $1.1 billion, net inflows of $0.8 billion and other movements of $0.7 billion.  Other movements primarily represent the AUM impact of the consolidation of a joint venture.

For the three months ended June 30, 2015, OMAM’s net flows were $0.8 billion compared to $(0.2) billion for the three months ended March 31, 2015 and $3.6 billion for the three months ended June 30, 2014.  Hard asset disposals of $(0.2) billion, $(0.3) billion, and $(0.6) billion are reflected in the net flows for the three months ended June 30, 2015, March 31, 2015 and June 30, 2014, respectively. For the three months ended June 30, 2015, the annualized revenue impact of the net flows was $13.5 million, as gross inflows of $7.5 billion during the three-month period were into higher fee asset classes yielding approximately 46 bps, versus gross outflows and hard asset disposals in the same period of $(6.7) billion out of asset classes yielding approximately 31 bps.  This is compared to the annualized revenue impact of net flows of $11.3 million for the three months ended March 31, 2015 and $18.4 million for the three months ended June 30, 2014 (see "Definitions and Additional Notes").

For the six months ended June 30, 2015, OMAM’s net flows were $0.6 billion compared to $2.6 billion for the six months ended June 30, 2014. Hard asset disposals of $(0.5) billion are reflected in the net flows for 2015 compared to $(0.9) billion in the net flows for 2014. For the six months ended June 30, 2015, the annualized revenue impact of the net flows increased to $24.8 million compared to $15.4 million for the six months ended June 30, 2014. Gross inflows of $14.5 billion in the six months ended June 30, 2015 yielded an average of 46 bps compared to 41 bps in the year-ago period while gross outflows and hard asset disposals of $(13.9) billion yielded only 30 bps in the six months ended June 30, 2015 compared to 37 bps in the year-ago period.

Balance Sheet and Capital Management

Selected Balance Sheet information as of June 30, 2015 and December 31, 2014 is provided in Table 3 below. The December 31, 2014 balance sheet is presented both on a U.S. GAAP basis, which includes Consolidated Funds, and on a non-GAAP basis which excludes those elements of Consolidated Funds which are not economically attributable to OMAM shareholders. As discussed below, in the first quarter of 2015, the Company adopted a new accounting standard which resulted in the de-consolidation of all Funds previously consolidated as of December 31, 2014. Therefore, the U.S. GAAP balance sheet as of June 30, 2015 is most comparable to the non-GAAP balance sheet as of December 31, 2014.

During the three months ended June 30, 2015 the Company made payments of $36.0 million and $32.0 million against notes payable to related parties and third party borrowings, respectively. As of June 30, 2015, the Company had third party borrowings of $145.0 million and shareholders’ equity of $106.1 million. The Company’s ratio of third party borrowings to trailing twelve months Adjusted EBITDA, excluding the extraordinary performance fee, was 0.6x, well below the maximum 3.0x leverage covenant under OMAM’s revolving credit facility. Of the Company's cash and cash equivalents of $178.3 million at June 30, 2015, $139.5 million was held at Affiliates and $38.8 million was available at the Company.

As of June 30, 2015, the Company had access to approximately $146 million of seed capital, provided by Old Mutual plc ("the Parent"), to invest in products managed by OMAM’s Affiliates. This seed capital is not reflected on the balance sheet of OMAM, as it is directly owned by a subsidiary of the Parent. In addition, at June 30, 2015, the Company had $34.4 million of co-investments in funds managed by its Affiliates on its balance sheet, with an off-setting liability to reflect those investments where economic ownership is retained by the Parent.

In February 2015, the FASB issued Accounting Standard Update 2015-02 ("ASU 2015-02"), Consolidation: Amendments to the Consolidation Analysis. The Company elected to early adopt ASU 2015-02 as of January 1, 2015, which has resulted in the de-consolidation of all previously consolidated funds as well as the removal of non-controlling interests on the Company’s balance sheet as of June 30, 2015 and statement of operations for the three and six months ended June 30, 2015. The Company elected to implement ASU 2015-02 using the modified retrospective method, which resulted in an effective date of adoption of January 1, 2015 and did not require the restatement of prior period results.

Financial Results: Non-GAAP Economic Net Income

In the second quarter of 2015, the Company recorded an extraordinary performance fee of $11.4 million ($0.09 per share), net of associated expenses and taxes. While all performance fees fall within OMAM's definition of economic net income, we believe that the unique characteristics of this fee, including its size and the extraordinary investment performance of the underlying product, make it unrepresentative of the Company's recurring economics. We have therefore presented our economic net income statement of operations with this extraordinary performance fee excluded from revenue and expenses and presented it on a net basis after economic net income before extraordinary performance fee. This presentation provides a more comparative view across reporting periods of the line items which make up ENI revenue and expense. Unless explicitly noted, the revenue, expense and key metrics discussed below exclude the impact of the extraordinary performance fee.

For the three months ended June 30, 2015 and 2014, diluted economic net income per share excluding the extraordinary performance fee was $0.32 and $0.28, respectively, an increase of 14.3%, on economic net income excluding the extraordinary performance fee of $38.0 million and $34.1 million, respectively, an increase of $3.9 million, or 11.4%.  For the three months ended June 30, 2015 and 2014, diluted economic net income per share (including extraordinary performance fee) was $0.41 and $0.28, respectively, an increase of $0.13, or 46.4%, on economic net income (including extraordinary performance fee) of $49.4 million and $34.1 million, respectively, an increase of $15.3 million, or 44.9%.  See Table 4 for a summary of economic net income and Table 12 for a reconciliation of U.S. GAAP net income attributable to controlling interests to economic net income.

For the three months ended June 30, 2015, compared to the three months ended June 30, 2014, ENI Revenue increased $17.3 million or 11.5%, from $150.5 million to $167.8 million, driven primarily by a 12.2% increase in management fees from $147.0 million to $164.9 million. Average assets under management in those respective periods, excluding equity accounted Affiliates, increased 8.8%, while the bps yield on these assets rose from 32.5 bps to 33.5 bps primarily due to an increase in average assets in higher fee rate global/non-U.S. and alternative products. Core operating expenses (before sales-based compensation and public company costs) increased 10.5% quarter-over-quarter. Including sales-based compensation and public company costs, total operating expenses grew 17.7% to $61.1 million, and total operating expenses as a percentage of management fee revenue increased to 37.1% from 35.3% for the three months ended June 30, 2015 and 2014, respectively. Total variable compensation grew 6.6% quarter-over-quarter to $43.7 million, while the ratio of variable compensation to earnings before variable compensation fell from 41.6% to 41.0%. The higher combined growth rate of operating and variable compensation expenses relative to revenue growth resulted in a decrease in OMAM’s ENI operating margin before Affiliate key employee distributions from 38.3% to 37.5%. For the three months ended June 30, 2015, expenses related to being a public company (excluding interest expense) totaled $2.8 million ($1.9 million of operating expenses; $0.9 million of variable compensation) and negatively impacted ENI operating margin by 1.7%. Affiliate key employee distributions increased 7.4% quarter-over-quarter to $10.2 million as a result of higher levels of Affiliate earnings, however the ratio of Affiliate key employee distributions over earnings before Affiliate key employee distributions fell from 16.5% to 16.2% primarily due to the repurchase of equity from an Affiliate in the fourth quarter of 2014.

For the three months ended June 30, 2015, Adjusted EBITDA, excluding extraordinary performance fee, was $54.4 million, up 9.7% compared to $49.6 million for the same period of 2014. See Table 13 for a reconciliation of economic net income excluding extraordinary performance fee to Adjusted EBITDA, excluding extraordinary performance fee.

For the six months ended June 30, 2015, compared to the six months ended June 30, 2014, ENI Revenue increased $39.1 million or 13.4%, from $292.0 million to $331.1 million, driven primarily by a 12.7% increase in management fees from $285.6 million to $321.8 million. Average assets under management in those respective periods, excluding equity accounted Affiliates, increased 10.1%, while the bps yield on these assets rose from 32.5 bps to 33.2 bps primarily due to a greater proportion of AUM coming from global/non-U.S. and alternative products. Core operating expenses (before sales-based compensation and public company costs) increased 11.1% year-over-year. Including sales-based compensation and public company costs, total operating expenses grew 17.0% to $120.6 million, and total operating expenses as a percentage of management fee revenue increased to 37.5% from 36.1% for the six months ended June 30, 2015 and 2014, respectively. Total variable compensation grew 8.6% period-over-period to $87.1 million, while the ratio of variable compensation to earnings before variable compensation fell from 42.5% to 41.4%. The consistent growth rate of operating and variable compensation expenses relative to revenue growth resulted in a slight increase in OMAM’s ENI operating margin before Affiliate key employee distributions from 37.2% to 37.3%. For the six months ended June 30, 2015, expenses related to being a public company (excluding interest expense) totaled $4.7 million ($3.4 million of operating expenses; $1.3 million of variable compensation) and negatively impacted ENI operating margin by 1.4%. Affiliate key employee distributions increased 6.3% period-over-period to $18.7 million as a result of higher levels of Affiliate earnings, however the ratio of Affiliate key employee

Exhibit 99.1

distributions over earnings before Affiliate key employee distributions fell from 16.2% to 15.2% primarily due to the repurchase of equity from an Affiliate in the fourth quarter of 2014 as well as the allocation of performance fee revenue.

For the six months ended June 30, 2015, Adjusted EBITDA, excluding the extraordinary performance fee was $107.9 million, up 14.8% compared to $94.0 million for the same period of 2014. See Table 13 for a reconciliation of economic net income before the extraordinary performance fee to Adjusted EBITDA, excluding the extraordinary performance fee.

References to “OMAM” or the “Company” refer to OM Asset Management plc; references to the “Parent” or “Old Mutual” refer to Old Mutual plc; references to the “Offering” refer to the Company’s initial public offering dated October 8, 2014 and references to the “Prospectus” refer to the Company’s Prospectus dated as of that date; references to the “Reorganization” refer to the steps taken by OMAM’s Parent prior to the Offering to reorganize the ownership of the business, as described in the Company’s Prospectus. 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, the fixed and variable components of compensation and benefits expense; and

• identify separately as Affiliate distributions the component of U.S. GAAP compensation that represents earnings shared with Affiliate key employee equity and profit-interest holders.

To reflect the Reorganization which took place at the time of the Offering, the Company has excluded:

i. notional corporate cost allocations which are non-cash expenses that will not recur following the Offering;

ii. interest expense historically paid to the Parent, as the related debt was restructured in connection with the Offering and thereafter has been eliminated from consolidated results; and

iii. historic mark-to-market co-investment gains and losses, because these investments and ongoing returns thereon have been allocated wholly to Old Mutual plc in connection with the Offering.

The Company also makes the following adjustments to U.S. GAAP results to more closely reflect its economic results by excluding:

iv. non-cash expenses representing changes in the value of Affiliate equity and profit interests held by Affiliate key employees. These ownerships 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.

v. 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. 

vi. 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.

Exhibit 99.1

vii. 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.

The Company adjusts its income tax expense to reflect any tax impact of its ENI adjustments.  Please see Table 12 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. For the period ended June 30, 2015, it is presented here excluding the impact of the extraordinary performance fee. 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 13 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.

ENI Operating Margin before Affiliate key employee distributions

ENI operating margin before Affiliate key employee distributions is a non-GAAP efficiency measure, calculated based on earnings after variable compensation divided by ENI revenue.

ENI Operating Margin after Affiliate key employee distributions

ENI operating margin after Affiliate key employee distributions is a non-GAAP efficiency measure, calculated based on earnings after Affiliate key employee distributions, divided by ENI revenue.

U.S. GAAP operating margin

U.S. GAAP operating margin equals operating income (loss) from continuing operations divided by total revenue.

Consolidated Funds

Prior to January 1, 2015, financial information presented in accordance with U.S. GAAP includes 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 which are not attributable to our shareholders.

Exhibit 99.1

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.

Hard asset disposals

Net flows in Table 2 and Table 7 include hard asset disposals made by OMAM’s Affiliates.  This category is made up of investment-driven asset dispositions made by 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. 34.3 bps in Q2 '15). For example, NCCF annualized revenue impact of $13.5 million divided by the average weighted fee rate of OMAM's overall AUM of 34.3 bps equals the derived average weighted NCCF of $3.9 billion.
