Long-term product offerings include alpha-seeking active and index strategies.
Our alpha-seeking active strategies seek to earn attractive returns in excess of a market benchmark or performance hurdle while maintaining an appropriate risk profile, and leverage fundamental research and quantitative models to drive portfolio construction.
In contrast, index strategies seek to closely track the returns of a corresponding index, generally by investing in substantially the same underlying securities within the index or in a subset of those securities selected to approximate a similar risk and return profile of the index.
Index strategies include both our non-ETF index products and iShares ETFs.
Although many clients use both alpha-seeking active and index strategies, the application of these strategies may differ.
For example, clients may use index products to gain exposure to a market or asset class, or may use a combination of index strategies to target active returns.
In addition, institutional non-ETF index assignments tend to be very large (multi-billion dollars) and typically reflect low fee rates.
Net flows in institutional index products generally have a small impact on BlackRock’s revenues and earnings.
Equity Year-end 2017 equity AUM totaled $3.372 trillion, reflecting net inflows of $130.1 billion.
Net inflows included $174.4 billion into iShares ETFs, driven by net inflows into Core funds and broad developed and emerging market equities, partially offset by non-ETF index and active net outflows of $25.7 billion and $18.5 billion, respectively.
BlackRock’s effective fee rates fluctuate due to changes in AUM mix.
Approximately half of BlackRock’s equity AUM is tied to international markets, including emerging markets, which tend to have higher fee rates than U. S.  equity strategies.
Accordingly, fluctuations in international equity markets, which may not consistently move in tandem with U. S.  markets, have a greater impact on BlackRock’s equity revenues and effective fee rate.
Fixed Income Fixed income AUM ended 2017 at $1.855 trillion, reflecting net inflows of $178.8 billion.
In 2017, active net inflows of $21.5 billion were diversified across fixed income offerings, and included strong inflows into municipal, unconstrained and total return bond funds.
iShares ETFs net inflows of $67.5 billion were led by flows into Core, corporate and treasury bond funds.
Non-ETF index net inflows of $89.8 billion were driven by demand for liability-driven investment solutions.
Multi-Asset BlackRock’s multi-asset team manages a variety of balanced funds and bespoke mandates for a diversified client base that leverages our broad investment expertise in global equities, bonds, currencies and commodities, and our extensive risk management capabilities.
Investment solutions might include a combination of long-only portfolios and alternative investments as well as tactical asset allocation overlays.
Component changes in multi-asset AUM for 2017 are presented below.
## Table 0 ##
(1) FutureAdvisor amounts do not include AUM held in iShares ETFs.
Multi-asset net inflows reflected ongoing institutional demand for our solutions-based advice with $18.9 billion of net inflows coming from institutional clients.
Defined contribution plans of institutional clients remained a significant driver of flows, and contributed $20.8 billion to institutional multi-asset net inflows in 2017, primarily into target date and target risk product offerings.
Retail net inflows of $1.1 billion reflected demand for our Multi-Asset Income fund family, which raised $5.8 billion in 2017.
The Company’s multi-asset strategies include the following: ?
Asset allocation and balanced products represented 41% of multi-asset AUM at year-end.
These strategies combine equity, fixed income and alternative components for investors seeking a tailored solution relative to a specific benchmark and within a risk budget.
In certain cases, these strategies seek to minimize downside risk through diversification, derivatives strategies and tactical asset allocation decisions.
Flagship products in this category include our Global Allocation and Multi-Asset Income fund families.  ?
Target date and target risk products grew 16% organically in 2017, with net inflows of $23.9 billion.
Institutional investors represented 93% of target date and target risk AUM, with defined contribution plans accounting for 87% of AUM.
Flows were driven by defined contribution investments in our LifePath offerings.
LifePath products utilize a proprietary active asset allocation overlay model that seeks to balance risk and return over an investment horizon based on the investor’s expected retirement timing.
Underlying investments are primarily index products.  ?
Fiduciary management services are complex mandates in which pension plan sponsors or endowments and foundations retain BlackRock to assume responsibility for some or all aspects of investment management.
These customized services require strong partnership with the clients’ investment staff and trustees in order to tailor investment strategies to meet client-specific risk budgets and return objectives.

Contractual Obligations, Commitments and Contingencies The following table sets forth contractual obligations, commitments and contingencies by year of payment at December 31, 2017:
## Table 2 ##
(1) Amounts do not include $350 million of cash payment consideration and contingent consideration related to the Company’s agreement to acquire the asset management business of Citibanamex.
(2) The amount of principal and interest payments for the 2025 Notes (issued in Euros) represents the expected payment amounts using foreign exchange rates as of December 31, 2017.
(3) The amount of contingent payments reflected for any year represents the expected payments using foreign currency exchange rates as of December 31, 2017.
The fair value of the remaining aggregate contingent payments at December 31, 2017 totaled $236 million and is included in other liabilities on the consolidated statements of financial condition.
(4) At December 31, 2017, the Company had approximately $365 million of net unrecognized tax benefits.
Due to the uncertainty of timing and amounts that will ultimately be paid, this amount has been excluded from the table above.
Operating Leases.
The Company leases its primary office locations under agreements that expire on varying dates through 2043.
In connection with certain lease agreements, the Company is responsible for escalation payments.
The contractual obligations table above includes only guaranteed minimum lease payments for such leases and does not project potential escalation or other lease-related payments.
These leases are classified as operating leases and, as such, are not recorded as liabilities on the consolidated statements of financial condition.
In May 2017, the Company entered into an agreement with 50 HYMC Owner LLC, for the lease of approximately 847,000 square feet of office space located at 50 Hudson Yards, New York, New York.
The term of the lease is twenty years from the date that rental payments begin, expected to occur in
McKESSON CORPORATION FINANCIAL REVIEW (Continued) 46 In July 2008, the Board authorized the retirement of shares of the Company’s common stock that may be repurchased from time-to-time pursuant to its stock repurchase program.
During the second quarter of 2009, all of the 4 million repurchased shares, which we purchased for $204 million, were formally retired by the Company.
The retired shares constitute authorized but unissued shares.
We elected to allocate any excess of share repurchase price over par value between additional paid-in capital and retained earnings.
As such, $165 million was recorded as a decrease to retained earnings.
The Company anticipates that it will continue to pay quarterly cash dividends in the future.
However, the payment and amount of future dividends remain within the discretion of the Board and will depend upon the Company’s future earnings, financial condition, capital requirements and other factors.
Although we believe that our operating cash flow, financial assets, current access to capital and credit markets, including our existing credit and sales facilities, will give us the ability to meet our financing needs for the foreseeable future, there can be no assurance that continued or increased volatility and disruption in the global capital and credit markets will not impair our liquidity or increase our costs of borrowing.
