Strategy Narrative [Text Block]	Under normal market conditions, the Portfolio pursues an active asset allocation strategy whereby investments are allocated among three asset classes: equity securities, debt instruments, and money market instruments. The Portfolio invests at least 50% of its total assets in common stocks. The remaining assets are generally invested in other securities, including convertibles, warrants, preferred stocks, corporate and government debt (including mortgage-backed and asset-backed securities), bank loans (which represent an interest in amounts owed by a borrower to a syndicate of lenders), futures and options, in keeping with the Portfolio's investment objective. The Portfolio may invest up to 25% of its net assets in foreign (non-U.S.) securities. The Portfolio may also invest in shares of affiliated and internally managed money market funds sponsored by T. Rowe Price. There is no limit on the market capitalization of the issuer of the stocks in which the Portfolio invests. The Portfolio's common stocks generally fall into one of two categories: the larger category is composed of long-term core holdings whose prices when purchased are considered low in terms of company assets, earnings, or other factors; and the smaller category is composed of opportunistic investments whose prices are expected by the sub-adviser or the sub-sub-adviser (together, the “Sub-Adviser”) to rise in the short-term but not necessarily over the long-term. The Portfolio may invest in bonds, convertible securities, and bank loans for their income, or other features, or to gain additional exposure to a company. Maturity and quality are not necessarily major considerations and there are no limits on the maturities or credit ratings of the debt instruments in which the Portfolio invests. Investments in a company may also be made through negotiated notes or loans, including loan participations and assignments. The Portfolio may purchase debt instruments of any maturity and credit quality. The Sub-Adviser may invest up to 30% of the Portfolio's assets in debt instruments that are rated below investment grade or, if not rated, of equivalent quality (commonly referred to as “junk bonds”). The Portfolio may invest up to 10% of the Portfolio’s assets in mortgage-backed and asset-backed securities. If a security is split rated (i.e., rated investment grade by at least one rating agency and below investment grade by another rating agency), the higher rating will be used for purposes of this requirement. The Portfolio may invest up to 15% of its total net assets in Rule 144A securities. The Portfolio may at times invest significantly in certain sectors, including the technology related sector. The Portfolio may invest in real estate-related securities, including real estate investment trusts (“REITs”). The Portfolio may also invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder. The Portfolio may invest in derivative instruments such as futures and options including puts and calls. Futures and options may be bought or sold for any number of reasons, including: to manage the Portfolio's exposure to changes in securities prices and foreign currencies; as an efficient means of adjusting the Portfolio's overall exposure to certain markets; as a cash management tool; to enhance income; and to protect the value of portfolio securities. Call and put options may be purchased or sold on securities, financial indices, and foreign currencies. Since the Sub-Adviser attempts to prevent losses as well as achieve gains, it typically uses a value approach in selecting investments. Its in-house research team seeks to identify companies that seem undervalued by various measures, such as price/book value, and may be temporarily out of favor, but have good prospects for capital appreciation. The Sub-Adviser may establish relatively large positions in companies it finds particularly attractive. The Sub-Adviser works as hard to reduce risk as to maximize gains. In addition, the Sub-Adviser searches for attractive risk/reward values among all types of securities. The portion of the Portfolio’s investment in a particular type of security, such as common stocks, results largely from case-by-case investment decisions, and the size of the Portfolio's cash reserve may reflect the Sub-Adviser's ability to find companies that meet valuation criteria rather than its market outlook. If there are remaining assets available for investment, the Sub-Adviser may invest the balance in any of the following money market instruments with remaining maturities not exceeding one year: (i) shares of affiliated and internally managed money market funds of T. Rowe Price; (ii) U.S. government obligations; (iii) negotiable certificates of deposit, bankers' acceptances, and fixed time deposits and other obligations of domestic banks that have more than $1 billion in assets and are members of the Federal Reserve System or are examined by the Comptroller of the Currency or whose deposits are insured by the Federal Deposit Insurance Corporation; (iv) commercial paper rated at the date of purchase in the two highest rating categories by at least one rating agency; (v) repurchase agreements; and (vi) U.S dollar and non-U.S. dollar currencies. The Sub-Adviser integrates environmental, social, and governance (“ESG”) factors into its investment research process for certain investments. While ESG matters vary widely, the Sub-Adviser generally considers ESG factors such as climate change, resource depletion, labor standards, diversity, human rights issues, and governance structure and practices. For certain types of investments, including, but not limited to, cash, currency positions, and particular types of derivatives, an ESG analysis may not be relevant or possible due to a lack of data. Where ESG considerations are integrated into the investment research process, the Sub-Adviser focuses on the ESG factors it considers most likely to have a material impact on the performance of the holdings in the Portfolio’s portfolio. The Sub-Adviser may conclude that other attributes of an investment outweigh ESG considerations when making investment decisions for the Portfolio. The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising. The Portfolio may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.
