Table of Contents ACCENTURE PLC NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (continued) (In thousands of U. S.  dollars, except share and per share amounts or as otherwise disclosed) Investment Strategies U. S.  Pension Plans The overall investment objective of the defined benefit pension plans is to match the duration of the plans’assets to the plans’ liabilities while managing risk in order to meet current defined benefit pension obligations.
The plans’ future prospects, their current financial conditions, the Company’s current funding levels and other relevant factors suggest that the plans can tolerate some interim fluctuations in market value and rates of return in order to achieve long-term objectives without undue risk to the plans’ ability to meet their current benefit obligations.
The Company recognizes that asset allocation of the defined benefit pension plans’assets is an important factor in determining longterm performance.
Actual asset allocations at any point in time may vary from the target asset allocations and will be dictated by current and anticipated market conditions, required cash flows and investment decisions of the investment committee and the pension plans’ investment funds and managers.
Ranges are established to provide flexibility for the asset allocation to vary around the targets without the need for immediate rebalancing.
Non-U.
S.  Pension Plans Plan assets in non-U.
S.  defined benefit pension plans conform to the investment policies and procedures of each plan and to relevant legislation.
The pension committee or trustee of each plan regularly, but at least annually, reviews the investment policy and the performance of the investment managers.
In certain countries, the trustee is also required to consult with the Company.
Asset allocation decisions are made to provide risk adjusted returns that align with the overall investment strategy for each plan.
Generally, the investment return objective of each plan is to achieve a total annualized rate of return that exceeds inflation over the long term by an amount based on the target asset allocation mix of that plan.
In certain countries, plan assets are invested in funds that are required to hold a majority of assets in bonds, with a smaller proportion in equities.
Also, certain plan assets are entirely invested in contracts held with the plan insurer, which determines the strategy.
Defined benefit pension plans in certain countries are unfunded.
Risk Management Plan investments are exposed to risks including market, interest rate and operating risk.
In order to mitigate significant concentrations of these risks, the assets are invested in a diversified portfolio primarily consisting of fixed income instruments and equities.
To minimize asset volatility relative to the liabilities, plan assets allocated to debt securities appropriately match the duration of individual plan liabilities.
Equities are diversified between U. S.  and nonU.
S.  index funds and are intended to achieve long term capital appreciation.
Plan asset allocation and investment managers’ guidelines are reviewed on a regular basis.
Plan Assets The Company’s target allocation for fiscal 2017 and weighted-average plan assets allocations as of August 31, 2016 and 2015 by asset category for defined benefit pension plans were as follows:
## Table 0 ##
Expenses The following table presents information on expenses for the years indicated
## Table 1 ##
Property Operations—The increase in property operations expense consists primarily of an increase of $19,607 related to acquisitions completed in 2017 and 2016.
We acquired 46 operating stores during the year ended December 31, 2017 and 99 stores during the year ended December 31, 2016.
Tenant Reinsurance—Tenant reinsurance expense represents the costs that are incurred to provide tenant reinsurance.
The change is due primarily to the increase in the number of stores we owned and/or managed.
Acquisition Related Costs and Other—For the year ended December 31, 2016, acquisition related costs represented closing and other transaction costs incurred in connection with our acquisition of operating stores, which were accounted for as business combinations.
On January 1, 2017, we adopted the guidance in ASU 2017-01, "Business Combinations (Topic 805) - Clarifying the Definition of a Business," which resulted in our acquisition of operating stores being accounted for as asset acquisitions rather than business combinations.
Accordingly, closing and other transaction costs have been capitalized in 2017 as part of the acquisition price for asset acquisitions, rather than being expensed as incurred.
General and Administrative—General and administrative expenses primarily include all expenses not directly related to our stores, including corporate payroll, travel and professional fees.
These expenses are recognized as incurred.
General and administrative expenses for the year ended December 31, 2017 decreased when compared to the same period in the prior year primarily as a result of an expense of $4,000 that was recorded during the year ended December 31, 2016 as the result of a legal settlement.
There were no such expenses during the year ended December 31, 2017.
We did not observe any material trends in specific payroll, travel or other expenses that contributed significantly to the increase in general and administrative expenses apart from the increase due to the management of additional stores.
Depreciation and Amortization—Depreciation and amortization expense increased as a result of the acquisition of new stores.
We acquired 46 operating stores during the year ended December 31, 2017, and 99 operating stores during the year ended December 31, 2016.
EXTRA SPACE STORAGE INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) Amounts in thousands, except store and share data, unless otherwise stated 4 Earnings Per Common Share Basic earnings per common share is computed using the two-class method by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding during the period.
All outstanding unvested restricted stock awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common stockholders; accordingly, they are considered participating securities that are included in the two-class method.
Diluted earnings per common share measures the performance of the Company over the reporting period while giving effect to all potential common shares that were dilutive and outstanding during the period.
The denominator includes the weighted average number of basic shares and the number of additional common shares that would have been outstanding if the potential common shares that were dilutive had been issued, and is calculated using either the two-class, treasury stock or as if-converted method, whichever is most dilutive.
Potential common shares are securities (such as options, convertible debt, Series A Participating Redeemable Preferred Units (“Series A Units”), Series B Redeemable Preferred Units (“Series B Units”), Series C Convertible Redeemable Preferred Units (“Series C Units”), Series D Redeemable Preferred Units (“Series D Units” and together with the Series A Units, Series B Units and Series C Units, the “Preferred OP Units") and common Operating Partnership units (“OP Units”)) that do not have a current right to participate in earnings of the Company but could do so in the future by virtue of their option, redemption or conversion right.
In computing the dilutive effect of convertible securities, net income is adjusted to add back any changes in earnings in the period associated with the convertible security.
The numerator also is adjusted for the effects of any other non-discretionary changes in income or loss that would result from the assumed conversion of those potential common shares.
In computing diluted earnings per common share, only potential common shares that are dilutive (those that reduce earnings per common share) are included.
For the years ended December 31, 2018, 2017 and 2016, options to purchase approximately 36,075, 45,286, and 88,552 shares of common stock, respectively, were excluded from the computation of earnings per share as their effect would have been anti-dilutive.
For the purposes of computing the diluted impact of the potential exchange of the Preferred OP Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, The Company divided the total value of the Preferred OP Units by the average share price of $90.30 for the year ended December 31, 2018.
The following table presents the number of weighted OP Units and Preferred OP Units, and the potential common shares, that were excluded from the computation of earnings per share as their effect would have been anti-dilutive:
## Table 2 ##
The Operating Partnership had $575,000 of its 3.125% Exchangeable Senior Notes due 2035 (the “2015 Notes”) issued and outstanding as of December 31, 2018.
The 2015 Notes could potentially have a dilutive impact on the Company’s earnings per share calculations.
The 2015 Notes are exchangeable by holders into shares of the Company’s common stock under certain circumstances per the terms of the indenture governing the 2015 Notes.
The exchange price of the 2015 Notes was $92.80 per share as of December 31, 2018, and could change over time as described in the indenture.
The Company has irrevocably agreed to pay only cash for the accreted principal amount of the 2015 Notes relative to its exchange obligations, but retained the right to satisfy the exchange obligation in excess of the accreted principal amount in cash and/or common stock.
