          Report of Independent Registered Public Accounting Firm

To the Participants and Administrator of the
Albany International Corp. Prosperity Plus Savings Plan

In our opinion, the accompanying statements of net assets available for benefits
and the related statements of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of Albany International Corp. Prosperity Plus Savings Plan (the "Plan") at
December 31, 2005 and 2004, and the changes in net assets available for benefits
for the years then ended in conformity with accounting principles generally
accepted in the United States of America. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with the standards of the Public
Accounting Oversight Board (United States). These standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) as of December 31, 2005 is presented for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in the audit of the basic financial statements and, in our
opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

Albany International Corp.
Prosperity Plus Savings Plan
Notes to Financial Statements
December 31, 2005 and 2004
--------------------------------------------------------------------------------

1.    Description of Plan

      The following description of the Albany International Corp. (the
      "Company") Prosperity Plus Savings Plan (the "Plan") provides only general
      information. Participants should refer to the Plan agreement for a more
      complete description of the Plan's provisions.

      General

      The Plan is a defined contribution plan and is subject to the provisions
      of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan
      covers all full time domestic employees of the Company and its
      subsidiaries who are 21 years of age or older.

      Contributions

      Employees may make voluntary contributions to the Plan of 1% to 15% of
      eligible compensation, subject to certain limitations, on a before-and/or
      after-tax basis as defined in the Plan. Participants may also contribute
      amounts representing distributions from other qualified defined benefit or
      defined contribution plans. Participants direct the investment of their
      contributions into various investment options offered by the Plan. The
      Plan currently offers thirteen registered investment companies, a
      common/collective trust and Albany International Class A common stock. The
      Company makes a matching contribution to the Plan in varying percentages
      up to 5% of the participant's eligible compensation (which may be in a
      combination of both shares of Company Class A stock and cash). Employees
      may convert any of the Albany International Class A common stock in their
      match and profit sharing accounts into the other available investment fund
      options.

      During 2005 and 2004, the Company's matching contributions of $4,260,993
      and $4,211,728 included $3,985,319 (116,711 shares) and $3,869,896
      (125,578 shares) of Albany International Class A common stock,
      respectively.

      Profit-Sharing Contribution

      The Plan provides for a profit-sharing contribution. Profit-sharing
      contributions are based upon a minimum 1% employee participation in the
      Plan and are in addition to, and separate from, Company matching
      contributions. In order to receive a profit-sharing contribution, an
      employee must be an active contributing participant in the Plan during the
      final quarter of the year for which the profit-sharing contribution is
      made, unless the employee has been suspended from participation because of
      a hardship withdrawal. If an employee is eligible, yet chooses to
      participate for less than a full year, the profit-sharing contribution
      will be pro-rated. An employee who retires during the year is also
      eligible to receive a profit sharing contribution on a pro-rata basis. The
      amount of the profit sharing contribution is based on a formula stated at
      the beginning of the year. The Company's contribution for profit-sharing
      may be made in either cash or Albany International Class A common stock
      (or both) following the end of the year.

      The profit sharing contributions were $2,256,903 and $1,481,418 for the
      years ended December 31, 2005 and 2004, respectively. Profit sharing
      contributions paid during the years ended December 31, 2005 and 2004
      included $1,371,376 (40,087 shares) and $1,624,315 (51,526 shares),
      respectively, of Albany International Class A common stock.

      Participant Accounts

      Each participant's account is credited with the participant's contribution
      and allocations of (a) the Company's contributions and (b) Plan earnings.
      Allocations are based on participant earnings or account balances, as
      defined. The benefit to which a participant is entitled is the benefit
      that can be provided from the participant's vested account.

      Vesting

      Participants are vested immediately in their and the Company's
      contributions plus actual earnings thereon.

      Pension Purchase

      The Plan allows retiring plan participants to purchase additional pension
      benefits by transferring existing Plan account balances to the Company's
      Pension Plus Plan. The decision to make a pension purchase must be made 60
      days prior to retirement. Once the pension purchase option is elected, the
      election is irrevocable after retirement.

      Payment of Benefits

      Upon termination of service, total disability, death or retirement,
      participants have the option to receive an amount equal to the value of
      their accounts in a lump sum payment or, in the case of total disability
      or retirement, monthly installments over a period not to exceed 15 years.
      Participants may also elect prior to retirement to withdraw up to 100% of
      their after-tax contributions and up to 100% of before-tax contributions
      if the Internal Revenue Service's criteria for "financial hardship" are
      met.

      Plan Termination

      The Company intends to continue the Plan indefinitely but reserves the
      right to modify, amend, suspend or terminate the Plan. In the event of
      plan termination, distributions would be allocated based on the value of
      the participant accounts.

      Administrative Costs

      The Plan stipulates that all costs incurred in administering the Plan
      shall be borne by the Company or, if the Employee Benefits Committee so
      determines, by the Plan. The Company paid Plan administrative expenses of
      $23,082 and $29,832 during 2005 and 2004, respectively.

2.    Summary of Significant Accounting Policies

      Estimates

      The preparation of the financial statements in conformity with accounting
      principles generally accepted in the United States of America requires
      Plan management to make estimates and assumptions that affect the reported
      amounts of assets and liabilities and disclosure of contingent assets and
      liabilities at the date of the financial statements and the reported
      amounts of changes in net assets during the reporting period. Actual
      results could differ from those estimates.

      Risks and Uncertainties

      The Plan provides for various investment options in any combination of
      stocks, bonds, mutual funds and other investment securities. Investment
      securities are exposed to various risks, such as interest rate, market and
      credit. Due to the level of risk associated with certain investment
      securities and the level of uncertainty related to changes in the value of
      investment securities, it is at least reasonably possible that changes in
      risks in the near term would materially affect participants' account
      balances and the amounts reported in the statements of net assets
      available for benefits and the statement of changes in net assets
      available for benefits.

      Investment Valuation and Income Recognition

      The Plan's investments are stated at fair value.

      Investments in registered investment companies are valued at the latest
      quoted sales price on the last business day of the year, which represents
      the net asset value of shares held by the Plan at year end.

      The investment in the common/collective trust is recorded at fair value
      based on the Plan's share of the fund's net asset value.

      On December 29, 2005, The Financial Accounting Standards Board (FASB)
      released FASB Staff Position Nos. AAG INV-1 and SOP 94-4-1, Reporting of
      Fully Benefit-Responsive Investment Contracts Held by Certain Investment
      Companies Subject to the AICPA Investment Company Guide and
      Defined-Contribution Health and Welfare and Pension Plans (FSP). The FSP
      clarifies the definition of fully benefit-responsive investment contracts
      for contracts held by defined contribution plans. The FSP also establishes
      enhanced financial statement presentation and disclosure requirements for
      defined contribution plans subject to the FSP effective for financial
      statements for issued for periods ending after December 15, 2006.

      Management intends to adopt the FSP in the Plan's financial statements for
      the year ended December 31, 2006. The effect of the FSP on the Plan's
      financial statements is expected to be enhanced financial statement
      presentation and disclosure requirements.

      Common collective investment funds will be presented at fair value on the
      statement of net assets available for benefits. The amount will represent
      the difference between fair value and contract value of the collective
      investment fund shall be presented on the face of the statement of net
      assets available for benefits as a single amount. This will be calculated
      as the sum of the amounts necessary to adjust the portion of net assets
      attributable to each fully collective investment contract from fair value
      to contract value. The statement of changes in net assets available for
      benefits shall be prepared on a basis that reflects income credited to
      participants in the Plan. This statement will include net appreciation or
      depreciation in the fair value of only those investment contracts that are
      not deemed to be fully benefit responsive.

      The common stock of Albany International Corp. is valued at the latest
      quoted price on the last business day of the year.

      Participant loans are valued at cost which approximates fair value.

      Security transactions are recorded on a trade-date basis. Gains or losses
      on sales of securities are based on average cost.

      Dividend income is recorded on the ex-dividend date. Dividends declared by
      the Board of Directors of the Company on Albany International Corp. Class
      A common stock may be reinvested in the Plan or received as a cash
      distribution as elected by the participant. Total cash dividends received
      by participants included in payment of benefits is $311,145 and $288,196
      for the years ended December 31, 2005 and 2004, respectively. Interest
      income is recorded as earned.

      The Plan presents in the statement of changes in net assets available for
      benefits the net appreciation in the fair value of its investments, which
      consists of realized gains and losses and unrealized
      appreciation/depreciation on those investments.

      Payment of Benefits

      Benefit payments are recorded when paid.

5.    Participant Loans

      Participants may borrow from their fund accounts a minimum of $1,000 and
      additional amounts in multiples of $500 up to a maximum equal to the
      lesser of $50,000 or 50% of their account balance. Interest rates on loans
      are determined by the Employee Benefits Committee from time to time with
      the rate remaining constant throughout the life of the loan (rates range
      between 4.94% and 10.08% at December 31, 2005). Loans are to be repaid
      through payroll deductions, although they may be repaid in a lump sum
      amount, generally over a period from 1 to 5 years except for loans for the
      purchase of a primary residence. Home purchase loan repayments range from
      5 to 20 years.

6.    Related Party Transactions

      The Plan invests in shares of mutual funds managed by an affiliate of
      Vanguard Fiduciary Trust Company ("VFTC"). VFTC acts as trustee for the
      investments held by the Plan. The Plan also invests in shares of the Plan
      Sponsor's Albany International Class A common stock. The Plan purchased
      $7,837,853 and $6,365,343 and sold $10,005,497 and $9,173,984 of Albany
      International Class A common stock during the years ended December 31,
      2005 and 2004, respectively. Transactions in such investments qualify as
      party-in-interest transactions which are exempt from the prohibited
      transaction rules.

7.    Tax Status

      The Internal Revenue Service has determined and informed the Company by a
      letter dated January 31, 2004, that the Plan is qualified and the trust
      established under the Plan is tax-exempt, under the appropriate sections
      of the Code. The Plan has been amended since receiving the determination
      letter. However, the Plan administrator believes that the Plan is
      currently designed and being operated in compliance with the applicable
      requirements of the Code. Therefore, the Plan administrator believes that
      the Plan was qualified and the related trust was tax-exempt as of the
      financial statement date.
